  Session 1

Eren doesn’t start out wanting to manipulate his patients into fucking him, really, it’s an honest mistake, an accident.

She comes to him through Armin, a good friend of his he’d met in graduate school, they’d both done their Master’s together and subsequently their practicum at the Shiganshina Wellness Centre.

It had actually been a favour to the blonde to take Mikasa on, Eren had more than enough on his plate after starting up his own practice a year out of school, he’d had no idea just how in demand therapists were these days.

It was a pleasant surprise to find out all the money he’d forked out to his university was finally paying off.

Armin of course couldn’t treat her himself, she was one of his best friends after all, so Eren had obliged, doing his friend a solid.

He’d actually been quite curious to meet the infamous Mikasa Ackerman, Armin’s childhood friend, only a few years younger, the girl he always spoke about with such fondness. In fact, Eren had wondered what she even had to talk to a therapist about at all. The way Armin told it Mikasa was a bit of a princess, came from a rich family, her mom from old money, and her dad, well he didn’t really know but it sure sounded like she lived a cushy life. 

What he did know about Mikasa was that she had attended Ivy League schools all her life, smart as a whip and at the ripe old age of 23 had climbed her way up high at some fancy investment company easily making six figures a year.

So, despite Eren’s code as a mental health professional to remain kind and nonjudgmental, he was judging, but only a little bit.

What the fuck did a pretty rich girl with everything going for her have to talk to him about?

For a full ten minutes before their first appointment he’d seriously questioned why he was bothering at all, glancing at the clock on the wall, leaning back in his chair impatiently, he had more important, more serious clients he could be dealing with.

And then, she’d walked in and very suddenly, it had all made sense.

Mikasa Ackerman was stunning, of course she was, it fit right in with everything else about her, made perfect fucking sense that on top of being smart, rich and successful she’d also be beautiful.

With eyes that glinted silver, hair that shined like stars in the night, and a body he wanted to lick every square inch of, he was tenting his pants almost immediately.

“Hi,” she’d said, her pretty face pulling up into a polite smile, delicate hand stretched out for a shake, “I’m Mikasa, Armin’s friend.”

“Eren,” he’d responded, his hand taking hers firmly as he stood from his chair, getting a better look at her, and fuck those tits, barely restrained by the casual white t-shirt she’d been wearing.

He’d known he was fucked almost immediately, his brain already trying to figure out ways to tell Armin it wouldn’t work out in a nice way, and not an ‘I want to fuck your best friend so badly I can’t be her therapist’ sort of way.

But not five minutes into the session, it had become immediately clear why Mikasa was there, her body language, the way she wouldn’t always meet his eyes when she talked, the obvious vulnerability in her voice as she awkwardly tried to explain her purpose for the session.

Mikasa Ackerman had daddy issues, and big ones as Eren learned only fifteen minutes into their first meeting. She didn’t have a dad, had been abandoned at the tender age of seven, just old enough for her to remember the man who’d been her father, just old enough for it to hurt, to cause permanent damage, abandonment issues galore.

And thirty minutes later, when their time is almost up, approaching the forty-five-minute mark is when Eren realizes just how easy it is to manipulate her, just how unbelievably damaged the sweet little thing is as she tearfully tells him about her most recent boyfriend, Porco. She details just how many times the dumbass cheated on her, how many times she went back, and now, how she’s been having trouble trusting again, opening up to someone even though there’s a nice new boy at her office who asked her out.

Mikasa is probably the finest specimen he’s ever seen, she’s fucking gorgeous, and exactly his type.

Sweet, beautiful, smart and subby as hell.

She craves a male authority figure in her life like she needs air to breathe, wants it more than anything, more than any other girl he’s ever seen.

It’s fucking hot.

It’s not really a conscious decision on Eren’s part as he wraps up the session, inviting her to take a seat next to him on the couch. She’s quick to do as she’s told, looking up at him with bated breath, like a puppy waiting for a treat, waiting to be told she’s a good girl.

He’s harder than he’s ever been in his life. She looks up at him with big watery grey eyes, plump lip quivering and downturned into a pout as she whispers the feared words, “Dr. Yeager, can you fix me?”

She looks utterly fuckable in that moment, and he thinks Dr. Yeager could sound a lot like ‘Daddy’ if he really wanted it to.

No, it’s not a conscious decision at all, because there’s no fucking way he could ever refuse this pretty girl, begging for his help, basking in his undivided attention, her every hope and desire pinned on him.

He’s going to fix her alright, make her perfect, just for him.

Session 2

“Good afternoon Mikasa,” Eren smiles as she steps into the room, her breathing heavy as she shuts the door behind her, breathless and late by only a few minutes. She collapses into the chair he gestures to across from him, the plush burgundy love seat moulding naturally to her form, like she belongs there.

And as she settles in, her black pencil skirt riding up, exposing a tantalizing glimpse of her thighs, Eren thinks she does, belongs just there right across from him.

“Hi Eren,” she tells him dropping her briefcase to the ground with a light thump, “Sorry I was a bit late I—”

“Dr. Yeager,” he corrects her, they can’t be too familiar, not yet, he needs to work her up to it, he needs to be her authority figure.

“Dr. Yeager,” she corrects herself with an exhausted smile, sinking further into the couch, her breath finally beginning to even out.

She looks even prettier today than she did last week during their first meeting, her pencil skirt sculpted to her form beautifully, showing off her ever curve, the plump of her ass to the delicate line of her waist. Eren licks his lips, mouth suddenly very dry as Mikasa makes herself comfortable. Toeing out of her heels, she exposes delicate feet, the backs of her ankles coloured slightly red from the harsh angles of her shoes. She hurriedly tucks her feet underneath her on the couch, showing off miles of smooth skin, and shapely calves, if she moves just so he knows he’ll glimpse a pair of panties.

The little minx, fuck.

She shuts her eyes for a moment, relaxing further into the couch before her delicate fingers begin deftly undoing a few of the buttons on her blouse. He cannot help but stare, especially as the tantalizing curves of her breasts are bared, pressing insistently against the fabric, just one more button and they’ll spill out, he can practically taste it.

She breathes a delighted sigh of relief as she’s freed from her confining top, opening her eyes finally to look at him, “Sorry Dr. Yeager, I’m just exhausted, I’ve been at work since five am this morning, it’s been a long day, and traffic was hell on the way here.”

Eren gives her a careful smile, thankful that he’d worn his looser slacks today so she can’t see how unbelievably turned on he is. She looks so fucking sexy, deliciously rumpled now that she’s made herself at home on his couch, like she’s just been freshly fucked after a hard day at the office.

Just like she fucking deserves.

God, this might be harder than he thought.

He remains composed, unaffected by her state of undress, how utterly fuckable she looks, Dr. Yeager the picture of professionalism. 

“That’s fine, Mikasa, but why don’t we start? Do you want to chat about your day or finish where we left off last session?” 

He’s quick, thorough, almost harsh in his dismissal of her day, almost mean, but that’s how it needs to be, he can’t be soft on her, not yet. 

She sits up a little in her seat, no longer so relaxed as the topic of discussion switches, a light frown puckering at her lips, “Sorry, yeah we should start from where we left off.”

She’s quiet, not elaborating, so Eren does it for her, “The intimacy issues you’ve been facing.”

She bites her lip, shrinking in on herself slightly, no longer the charming businesswoman fresh from work, her confidence leaking out like air from a balloon, “Yeah.”

“And what do you think triggered that?”

She sighs, deflating, “My relationship with Porco, all the cheating.”

“Hmm.”

That’s all it takes, so fucking easy, barely a murmur from him and she’s baring her soul, “But more than that it’s that I stayed with Porco for so long isn’t it?”

She looks up at him, grey eyes earnest, sparkling with the need for approval, her desire to be right, to be praised and rewarded for her insight and Eren is more than happy to give it to her.

“Exactly right Mikasa, good girl.”

She perks up at his praise, giving him a faint smile. 

“And why do you think you stayed for so long?”

Her brow furrows at this, “I don’t know I guess, I just, I needed someone, Armin is always busy and my mom is away on business, I’ve been lonely, and Levi well he’s deployed right now.”

Eren hums, “Your brother right?” 

“Yeah, I just feel so alone, so it was nice to have someone for a while, even when he did cheat I could look past it.”

God, she’s so fucking perfect, so utterly alone, she has friends sure, Mikasa did her fair share of chattering about what an amazing best friend she has. Sasha, if he can recall correctly, but she doesn’t really have any men in her life she can count on, no one that sticks around.

“I see,” Eren says, scribbling a quick note down into the margins of his notepad, and Mikasa immediately looks concerned as she hears the scratch of his pen but he’s quick to reassure her.

“It’s nothing Mikasa, don’t worry sweetheart,” he stands, discarding his notebook as he comes to kneel in front of her on the couch. Gently, he places his hand on her knee, a soft comforting touch, but just enough pressure to let her know he’s there, get her used to it. 

She nods, assured, barely flinching at the term of endearment, unphased, she’s like his perfect patient, everything he could have asked for and more. 

“Thanks, Eren I just–.”

“Dr. Yeager,” he corrects again and she smiles, bashful, mumbling her correction back, “Dr. Yeager.”

He smiles, “Yes.” 

“I just, I get nervous when you write stuff down, it’s silly actually, I feel like I want to be good at everything,” she laughs, “even therapy, it’s dumb really.”

“No it’s okay,” he tells her, rubbing circles over her knee, soft, unblemished, and she relaxes a little more. 

“It’s normal in therapy, a lot of patients feel like that, but I promise this is a safe space. I’ll never judge you. I’m here for you Mikasa,” he tells her, green eyes locked on her own silver ones, imploring her to believe him, to understand how seriously he takes his job.

“Thank you,” she tells him finally and he nods, giving her knee a gentle squeeze before moving back to his seat, “Of course Mikasa, now let's continue.”

She nods resolutely.

“So Porco cheated on you a lot, and you stayed because you felt lonely, were you two engaging in a lot of intercourse at the time?”

Mikasa blushes bright pink, her cheeks colouring slowly, pinking up the tops of her breasts and down her neck, so fucking pretty. 

She struggles to answer for a moment, “I umm–” 

“It’s a completely normal question, remember no judgment, Mikasa.”

“Well I erm, I guess, it wasn’t as much as it was before, but we still had sex a fair amount.”

“How often?”

“A few times a week.” 

“Hmm, interesting.”

“Why?” Mikasa practically bursts out and Eren gives her an amused smile, “I wouldn’t exactly consider that often.” 

Her cheeks are permanently red at this point, her face the colour of a fire truck, and Eren thinks it’s cute how easily she blushes. 

“So then what would you consider often Dr. Yeager?”

He shrugs, blasé, “It’s different for everyone, I myself am more of a daily kind of guy though if I’m being honest.”

“Oh,” she whispers, her mouth parting into a sweet little ‘o’ as she thinks on that, and he watches smugly as her eyes dart over his form, evidently sizing him up, seeing him as a man and not just her therapist, just like he wants.

“Were you sexually satisfied during most of these encounters with your ex?”

Eren is quick to jump to the next question and Mikasa is spooked almost immediately, coming out of her shock, “What? How is that relevant?”

Eren quirks an eyebrow at her, “Well Mikasa, in my humble opinion at least, it brings a whole new level of dysfunction to your relationship if not only is he cheating on you, but the sex is also bad.” 

“Umm, right,” she mumbles in embarrassment, “I guess, it was a pretty dysfunctional relationship then because no, I usually wasn’t sexually satisfied.”

And what a crying fucking shame that is, jesus christ, he has half a mind to beat her shitty ex to a pulp for just breathing the same air as her now. He can practically feel the veins in his forehead becoming more prominent as he struggles to keep his composure, leaving a masterpiece like Mikasa unsatisfied is truly a crime. 

“Do you think that might also have something to do with your current inability to initiate a relationship?”

“Maybe,” she whispers after a long moment, surprised at her own admission, and already Eren know this is going to be everything. 

  Session 3

“So Mikasa,” Eren prods, his legs crossed as he sits in the chair across from her, slacks stretched tight over his thighs, he’d had to wear his smaller ones today, running out of laundry as he hits the end of the week. He’d felt uncomfortable at first, wondering if it was too much but somehow, as Mikasa’s eyes fight not to look at his obvious dick print, he doesn’t think she minds so much. 

“Do you think the psychological challenges you’ve been facing, your fears of intimacy, have been hindering you physically as well as mentally?”

Her gaze snaps up to his face as she takes in his statement, her expression curious as she tries to figure out what he means by that, “I don’t understand.”

He hums contemplatively, how should he say this?

“Do you think that you’ve been having a hard time performing sexually because of your intimacy issues?”

“I mean I think so? Otherwise, I wouldn’t be here right, I’d be out with Colt.” 

Eren sighs in exasperation, “That’s not what I mean.”

“Please explain,” Mikasa tells him sweetly, so eager to understand, always such a good fucking patient, she makes it so unbelievably easy.

“I mean, and forgive me for being crude Mika, but are you feeling healthy, sexually I mean? Are you able to get turned on? Do you get aroused like you used to, or has that been hindered as well?”

“Oh, oh no, not at all, I mean umm yes, yes I can still–” She cuts herself off, her hands coming up to hide her face as she pinks up, “Yes Dr. Yeager, I still get turned on.”

“Well, I’m happy to hear it,” he chuckles.

“Yeah,” she slowly brings her hands down, “Everything is completely normal.”

“Perfect, so nothing different then, you haven’t noticed yourself being aroused by any new or different stimuli?” 

She laughs nervously, her hands fiddling with the hem of her dress, “Sorry, it’s just such a weird conversation to be having with your therapist.” 

He leans over the coffee table to place a careful hand on her knee, “Not at all, you don’t have to be embarrassed with me Mikasa, what do I always tell you?”

She sighs, shaking her head fondly as she repeats his words back to him, “This is a nonjudgmental zone, I’ll be safe.”

He gives her leg an affectionate pat, “Good girl.” 

Eren relaxes back into his seat, reluctantly pulling his hand from the smooth skin of her leg. He slips his glasses up his nose before grabbing for his pad and paper again, “Now, tell me Mikasa, have you noticed any differences when you touch yourself?”

She takes a deep breath, crossing her legs at the thought, the sweet little thing getting squirmy as she thinks about it, god she’s probably wet right now, he’s sure of it. Dressed in that tiny little blazer dress today that barely covers anything, she’s borderline indecent, the V of the neckline plunging so low and the hem so short, he can see every inch of her perky tits and just the edge of that plump little ass on display. 

He wonders if she’s wearing panties at all, what colour they are, are they lace? Or better yet, if she’s wearing none at all, her essence leaking onto his couch, fuck.

Eren discretely adjusts himself in his pants as Mikasa answers him, “I umm, I guess sort of, I haven’t been doing it as often, nothing has really been doing it for me lately.”

“Speak clearly Mikasa, what do you mean?” He prods her, his tone sharp, she needs a firm hand, and just like always the authority in his tone bolsters her, her reply immediate this time if a little breathless, “I can’t get off.” 

He nods, writing it down in his notebook and as always Mikasa pouts a little, ever the eager patient, wanting to be the best, perfect even at therapy. 

She’ll never know it but she already is, the best patient he possibly could have asked for. Eren snaps his notebook shut, looking over at the time, they’re almost done for today, a short session he’d squeezed in before the end of the week.

“I’m afraid we’re almost out of time Mikasa.” 

“What?” She gasps, looking up at the clock, her expression frantic, “No, that can’t be it, Dr. Yeager please just a few more minutes I think we’re really getting somewhere today.” 

He gives her a gentle smile, leaning over the coffee table for another touch to her knee, his hand resting a little higher this time, skimming the hem of her dress, his thumb rubbing soothing circles along her inner thigh, “Don’t worry Mikasa, it’s not over yet sweetheart, I have some homework for you, actually.”

She looks at him, her expression unsure, wanting to continue and Eren wants nothing more than to sit here for the rest of the afternoon and let her tell him about how she can’t get off, but really, it’s better if he makes her wait, lets her go home pent-up and frustrated. 

He reassures her again, looking deep into her eyes, his other hand betraying him, coming up to cup her cheek, “This is a perfect place to end, don’t worry ‘Kasa,” he whispers, “Would I ever steer you wrong?”

“No,” she murmurs back, leaning into his touch and he smiles, so fucking perfect and responsive.

“Of course not, so why don’t I tell you about your homework?”

She nods, whimpering as he removes his hands from her and Eren takes it as his opportunity to sit next to her on the couch, shushing her quietly as he grabs for his laptop. He tucks her under his arm on the couch under the guise of showing her the homework he’s come up with for her. 

“I think an important part of improving how open you are sexually is exposing you to new stimuli Mikasa,” he tells her as he opens his browser, typing in his favourite porn site.

“Oh,” she gasps under his arm, the sweet little noise going straight to his dick as a host of videos appear on the screen, girls getting fucked in all variety of ways, she’s jarred by the image.

He balances his laptop on his knee with one hand, his other coming around to her hip, a comforting touch as she takes it all in, “I know it’s a lot, a bit unorthodox,” he chuckles, “but I think this could really work for you Mikasa, there's been great success with this in the therapy world lately.”

“Really?” She looks up at him, innocent, earnest and so fucking willing, willing to do whatever he says and just the hint of lust in those silver eyes of hers as he cuddles her closer. He knows she’s not unaffected by him, by his body, is fighting so hard against it, but as he rubs at the curve of her hip he wants her to submit, be attracted to him. 

“Yes, I think it’s really important for your treatment in particular Mikasa, it’s not just about the psychology of it all, I don’t want there to be any long-lasting effects either, it’s important to nip this in the bud now so we can move on to more serious matters.”

“Like my abandonment issues,” she mumbles mournfully and Eren tugs her closer, “Anything you need sweetheart.”

She nods into his chest, relaxing into him, her gaze drawn back to his laptop as she scans over the many videos on the front page of the site. Almost unconsciously, she reaches out, a delicate manicured finger trailing along the screen as she looks over the videos. Her finger stops on one particular image of a large man fucking into a pretty dark-haired girl from behind and Eren can barely restrain himself at her reaction. Mikasa’s breath hitches as she admires the image, her hand tracing down the large form of the man and Eren hovers the mouse over the video, watching in interest as the thumbnail plays a short snippet. 

“Wow,” Mikasa whispers, entranced as she watches the expression of complete bliss on the girl’s face, the brief glimpse of the man’s thick girth before he slips back inside her.

It’s perfect, she’s already drawing comparisons between them, that could be him and her in that video, it’s exactly what he wants, but just as he’s about to say something about it, make her pretty little brain really think about it, she changes the subject, clearing her throat, “So umm what exactly should I be doing? Going home and watching porn?”

He makes a clicking noise with his tongue, “Of course not, there is a method to my madness Mikasa, I’ve curated some specific videos for you to watch.”

“Oh?” She murmurs, her finger falling from the screen as she looks up to him for guidance, that pretty face, so ready and willing to listen to him, the petal pink of her lips, that cute little nose to the little scar on her cheek he wants to lick, she’s fucking perfect.

“Yes, I want you to tell me which ones turn you on the most, what you notice about the videos, how you feel watching them. Keep a journal and next session we’ll go over it all.”

She swallows, “Okay, I- how do I know which ones to watch?”

“I’ve sent them all in an email to you.”

She nods just as the timer on his desk goes off and he snaps his laptop shut, placing it on the side table next to him. She’s still tangled in his arms, her cheek pressed against his chest, looking up at him so prettily, and he thinks she’d look even prettier on her knees, that sinful mouth wrapped around his cock instead.

He gives her hip a squeeze as he slowly detangles himself from her, and he adores the little pout that mars her face as he pulls away, god it’s so fucking obvious how much she needs him, craves his touch, his approval. Giving her up after every session is hell itself, but it’s a necessary evil because one day she’ll stay forever, and that’s all he really needs. 

“I think this is as good a place as any to end for the day Mikasa, do you have any other questions at all about your homework?”

She shakes her head as Eren pulls away fully, standing up to grab her coat for her, “No, but I’ll get started right away Dr. Yeager.”

So fucking eager, and if possible he gets ever harder in his pants, imagining her going straight home to watch the videos he’s chosen for her, to touch herself thinking of him. 

“Of course Mikasa,” he shoots her a charming smile, patting her head approvingly, “Such a good patient.”

She lavishes under his praise, “I’ll do everything you said, write it all down, I’m going to ace it, I’ll think of you.”

Her eyes widen as soon as the words leave her lips and she makes an adorable little ‘oof’ noise as she struggles to recover, stumbling over her words, “Sorry I didn’t mean it like–”

He gives her an amused smile, waving off her apologies, “You should think of me Mikasa, you need to in order to complete the assignment properly. As your therapist I need to know every detail, don’t leave anything out.”

His hand slips from her head down to cup the nape of her neck almost possessively, his thumb tracing the line of her jaw, “I need to know if you cum, how it happens, how many fingers you use, if you use any toys, and if you’re thinking about anyone in particular.”

He looks at her seriously, “That part is really important ‘Kasa, I need to know if you think about Porco, or someone else, another man in your life, an authority figure, it’s very integral to exploring the depth of your issues.”

“Of course Dr. Yeager,” she whispers breathlessly, “I’ll do it all, I won’t leave anything out.”

“Good girl,” he praises her, his hand still stroking her jaw before he reluctantly pulls away.

“Make sure it’s done by next session.” 

“I will,” she promises him and Eren turns away, back to his desk, because he has to be the aloof authority figure she needs, the man she craves approval from, just like her dad.

Fuck. 

Session 4

“Did you watch them all?”

Mikasa nods, uncharacteristically shy today, she’s huddled up on the corner of the love seat where she usually sits in the middle, a little closer to him, but today her body language is shy, closed off.

He’ll have to change that, especially if they’re going to go over her homework assignment.

“I presume you have the journal?”

She nods again, before reaching into her bag to hand the leather bound journal to him weakly.

Perfect, he’ll have to read it later.

He takes it from her hands, leaving it on his desk and Mikasa frowns as he puts it away, “We’re not going to go over it?”

“Not today, I’m going to read it myself first. Today, we’re just going to discuss the assignment.”

“Oh, okay,” Mikasa mumbles, huddling back into the corner of the couch.

“So, what did you think?”

“It was umm, illuminating I guess?”

“What did you think of the videos I selected?”

She swallows, her throat bobbing with the motion. 

“They were nice,” she responds vaguely and Eren’s brows furrow, she’s being a pain today, so unlike his favourite patient, but he supposes he should have expected some barriers, at least with this part.

“Let me rephrase Mikasa, did you cum?”

“Yes,” she whispers, turning to look out the window instead of meeting his eyes.

“How many times?”

Her gaze shoots back to glare at him, her brow scrunching up in annoyance, and how fucking cute, she’s so embarrassed she’s angry about it, “A lot.”

“Did you orgasm to every video?”

“Yes,” she grits out and Eren can’t help a wide smile, that means she liked them, every one he’d chosen. This pleases him immensely, the list had been curated very carefully.

“Good girl, I’m so happy for you.”

“Thanks,” she tells him somewhat sarcastically as she turns back to the window.

Now she’s just being a brat though and he can’t have that, “Mikasa,” he says harshly, “If you’re not interested in engaging in the session today feel free to leave, I have other clients I could be seeing right now.”

At this her attention is all on him, desperately shaking her head, “No, no I’m sorry Dr. Yeager, I’m just really embarrassed.”

His nostrils flare in irritation and he barely has to say a word before Mikasa is already apologizing again,

“I know, I know this is a safe space, I’m just -I’m a little shy, I’m sorry.” 

Tears leak from those pretty grey eyes of hers, turning them silver as she pleads with him not to end the session, “I’m sorry, I’ll be good I promise, I’ll engage.”

“Oh sweetheart, don’t cry, come here,” he gestures for her to come to his chair, sit in his lap and she comes so willingly, like a puppy to its owner. 

“Oh sweetheart,” he comforts her as she goes into his arms, allowing him to take her into his lap, “Would you feel more comfortable here, could you tell me now?”

She nods meekly and he drops a light kiss to her forehead as he settles her into his lap, her head tucked under his chin, legs splayed out over the arm of his chair. He rubs along her calves and up to her thighs, long, slow strokes she’d never mistake for anything but innocent, comforting.

“So tell me love, which was your favourite?”

“The one with the therapist,” she whispers breathlessly and Eren hides his smile in her hair, humming to her in response.

“And why do you think that was?” 

She squirms in his lap as she thinks on it, Eren fighting not to press her closer, let her really feel what she’s doing to him, the obvious bulge in his pants.

Finally she answers, breathless and worried about his reaction, “I just umm, I liked their dynamic,” she tells him vaguely and Eren frowns but doesn’t press her more on the topic.

Although it’s progress that she’d so obviously been interested in the video involving the fake therapist, he’d hoped she’d have a better reason for it than that, but he supposes not everything can be perfect.

“What else did you notice ‘Kasa?”

“Umm,” she swallows, “I noticed that in a lot of them, they called the guy ‘daddy’.”

“I hadn’t noticed that, great observation, Mikasa.”

She turns to him, surprised, her expression bewildered, “You mean you didn’t choose them for that reason?”

Eren looks at her with faux surprise, “Of course not, I chose at random, made sure I had some variety, I just wanted to know which ones stood out to you. But it’s really interesting that that’s what you picked up on.”

Sure, interesting, as if he hadn’t handpicked every fucking video with the express purpose of bringing out her daddy kink. It’s a good thing he’s a good liar. 

Mikasa winces, “Is that okay? Why is it interesting?”

“Not to worry Mikasa there’s nothing wrong with you,” he soothes, “It’s just interesting that you’d notice, tell me did you enjoy it when they spoke like that?”

She squirms a little in his arms and Eren holds her tighter, “If I’m being honest, yes, I umm especially liked that one video.”

“Which one?”

“The third one on the list,” she murmurs and he can feel how heart rate picks up at the mere mention of it, and that’s exactly the one he’d liked most too, the one he’d been hoping she’d have a reaction to. 

“What did you like about it baby?”

He just slips, it’s an honest mistake and Mikasa, so engrossed in the discussion, is none the wiser. 

“I just thought it was really nice how they took care of each other.”

“What do you mean?”

“Well, he went down on her and she seemed to like it, which Porco never did for me–”

Eren cuts in, “And that’s not okay, remember what we talked about before Mikasa, you deserve pleasure too.”

“Yeah,” she continues, “And then when they had sex, that was umm really hot, but most of all, at the end I liked how she umm returned the favour.”

Mikasa skips over the lewd act like it’s taboo, like she’s not adding fuel to the fire of his libido, even better than he could have hoped. 

“So you enjoy that it was reciprocal, that they both enjoyed themselves.”

She nods but Eren continues, wanting the words said in the open, “You liked that afterwards she got down on her knees to give the man a big thank you for giving her such nice cock.” 

She nods again, unable to say more and Eren smiles, and he knows it’s sharp, that his edge is showing but he can barely help himself, she’s so fucking perfect. 

“That’s wonderful Mikasa,” He murmurs, “You’re so giving and that’s great to hear, it shows me that even though you’ve been through so much that you’re not afraid to give.”

“So I’m not a lost cause?” She asks, a note of excitement in her voice and Eren smiles, “Not at all, I think with some good exposure therapy and continuing our sessions we can get you back on the right track.”

“Oh Dr. Yeager that’s wonderful.”

He grins wickedly, all teeth, “Yes, now why don’t you tell me exactly what else you liked about that video?”

Session 5

Through Mikasa’s journal and her complete devotion to therapy Eren learns several things about her. First and most obviously, she has a major daddy kink, wants nothing more than to be taken care of, likes to be ordered around. She’d all but admitted it, telling him rather candidly that she just wanted to lose herself during sex, let her partner take the reins, her everyday life was stressful enough. 

Mikasa wanted a daddy, someone to take care of her, love her, make everything okay, she just hadn’t admitted it to herself quite yet, and well, that was where Eren came in, he was her therapist after all. His whole job was to help her discover new things about herself and he was more than happy to oblige.

Her journals also yielded some new information as well, he’d barely made it half a page before he was palming himself just to find some relief while reading her detailed analysis of each video.

Mikasa liked big dicks, that became obvious after reading pages and pages of her salivating over the sheer size of the men in the first four videos he’d recommended. How her writing would sometimes cut off, and she’d restart a few lines later, unable to articulate herself, probably having to watch it again.

He was fucking elated, because his length was nothing to sneeze at, and surely it would tempt her towards the path of no return. 

But there were other things too, things he had yet to even explore with her, and today, he planned on furthering his plan to seduce his patient. Today, he was going to tackle her self-esteem. 

For all intents and purposes Mikasa was a beautiful, smart and confident woman, she had a high-powered career and knew how to hold her own in the corporate world. But with him, with him she melted, soaked up every word of praise he gave her, basking in it, so intent and adoring. 

With him, she was no longer the confident corporate businesswoman, she was Mikasa, the fatherless little girl who craved daddy’s approval, to understand why she was left in the first place. She was insecure, unsure of herself, stuttering, fumbling over her sentences in embarrassment, fucking adorable sometimes. 

And today, he was going to push her on it. 

He wanted to see those fucking tits, and if he had it his way, he would. 

“Good afternoon, Mikasa,” Eren greets her casually as she steps into his office, before going back to his work at his desk while she gets settled.

He doesn’t acknowledge her again for several minutes as he finishes writing out his notes from his last session, completely ignoring his favourite patient, the room quiet save for the tick of the clock on the wall.

He can tell it’s bothering her, how she fidgets, looking around the room nervously, wanting his attention but unsure how to get it. 

But she says nothing, trying to be good, that deep part of her ingrained to obey his silent order to be quiet, wait to be acknowledged, listen to Dr. Yeager, please Dr. Yeager.

He inhales sharply as his imagination starts to get the better of him, her obedience going straight to his head. 

Mikasa clears her throat, restlessly readjusting her position for the third time and Eren fights the urge to look up, he can’t give in, not just yet.

Finally, a very meek whisper follows when he doesn’t give her the attention she longs for,  “Eren?”

“Dr. Yeager,” he corrects easily before looking up at her, “Are you ready to begin love?”

She nods quickly and he gives her a smile, “Thank you for waiting, I appreciate your patience.”

“Of course,” she replies and Eren takes his place in the large armchair across from her. There he can stretch out, size her up, make her the centre of his attention. 

“Today Mikasa, I want to discuss something different than last time, something I’ve been noticing a lot with you lately.”

“What is it?” She questions anxiously, her hands twisting together with nerves at the very idea of disappointing him somehow, that there could be something wrong.

“Your self-esteem.”

She looks surprised, her full lips parting in shock, “But I think my self-esteem is fine?” 

“It’s not,” Eren tells her sternly, “I can see it just in your body language love, you’re very insecure, especially with men and we’ll need to change that if you plan on ever being intimate with someone again.”

Her mouth snaps shut, brows furrowing as she looks down at herself contemplatively, “You really think so?”

“I know so, Mikasa, you wouldn’t even meet my eyes last session when we were talking about sex.”

“Wow,” she murmurs, tearing up slightly, “You really think I have low self-esteem?”

He nods, cementing it into her pretty little brain, “I can tell just by the clothes you wear Mikasa, you’re especially insecure about your body, your breasts.”

Mikasa looks down at herself self-consciously, her eyes bright as he catches on a nerve, her arm coming up to try and hide the breasts she’s so shy about.

“Oh sweetheart,” he murmurs lovingly and already he can see the tears slipping down the apples of her cheeks. 

Eren is quick to come to the rescue, moving to the seat next to her, caressing down her arms, “But we’ll fix it, don’t worry. You’re such a pretty girl Mikasa, you deserve so much, you deserve a boyfriend who appreciates you.”

She sniffles, subconsciously inching closer to him, aching to be in his arms, the comfort he provides and Eren is happy to give it to her, allowing her to burrow into him. 

He kisses her forehead as her lithe little body cuddles in, practically in his lap, one hand wrapped around her waist, caressing over the divots of her spine, just under her t-shirt feeling at soft skin while he continues his charade.

“I know you’ll come out of therapy fine baby, you deserve everything, to be able to find a partner again, no intimacy issues.” 

She sniffles as he takes her into his arms, “They’ve always just been so big, and other girls used to make fun of me about them.”

She hiccups as she continues, tears flowing freely now, “Especially in high school, mom would tell me they were just jealous, but they were always so mean.” 

“Shh,” Eren soothes, combing her hair back, “They were jealous baby, jealous of such a pretty girl.”

“But Porco too–” Mikasa breaks off on a sob, “He told me they made me look fat, that I should lose a few pounds.”

Eren clenches his fist, fighting not to go and find this man, burn him to the ground, but he has Mikasa in his arms to think about, “He’s an idiot.”

Mikasa chokes on a laugh, “But he’s an idiot I dated, I wanted him.”

She breathes in harshly as she struggles through her sobs, getting out all her truths, her makeup running down her cheeks, ruining her mascara but only accentuating just how pretty she looks all ruined, “It’s so stupid now, I wanted him to want me so bad Eren.”

He doesn’t even try to correct her this time, quick to reassure her, taking his perfect opportunity as he shushes her, running his fingers through her hair comfortingly, “That’s normal Mikasa, you cared for him, but you have to remember baby you deserve more.”

He pulls back, reassuring her, his gaze locked on hers, “Such a pretty girl like you deserves to be fucked how she wants, to be taken care of, to feel comfortable in your body, and we’ll work on it okay, I promise.”

He tilts her chin up, forcing her to look at him, watery grey mixed with speckles of obsidian, coal eyes emphasized even more by her running mascara, she’s breathtaking as always, even prettier when she cries.

“We just need to work on it, get you comfortable in your own skin.” 

She sniffles and he swipes the tears from her cheeks roughly, cupping her jaw in his hand, he fucking owns her, especially when she nods, so obedient, willing to do whatever he says, “How should we do that Dr. Yeager?”

“Let’s start right now sweetheart, why don’t you take off your shirt?” 

She looks shocked and for a moment, Eren worries he’s fucked up, that he’s gone too far, but before his panic can truly set in Mikasa is pulling back, moving away from him and Eren watches in horror as she stands from her perch on his lap.

Fuck, it’s all over.

But, then to his amazement, she grabs for the hem of her t-shirt, standing tall in front of him, giving him a prime view as she takes her shirt off, exposing the full rounds of her breasts, held up only by a lavender bra.

She’s stunning, even better than he could have hoped, he can see the dark spots of her nipples barely hidden by the light colour of her bra, how pretty pink they are, a nice blush colour. 

“Bra off too,” He murmurs almost in a trance and Mikasa is eager to obey, her hand nervously slipping to the back of her bra to unclasp it.

She unveils herself slowly, unsure, the heavy weight of her tits sagging just slightly as she’s released from her bra, and fuck she’s all-natural.

Some part of him had wondered, tits like that, just had to be implants, but no, not hers, perfectly round and full, just begging to be touched, suckled at, fuck. 

He can barely stop himself as he reaches out, skimming the pad of his index finger along the tops of her breasts and Mikasa shivers in response, her eyelids fluttering at the sensation. 

“Don’t you ever hide these Mika, they’re a gift, show them off.” 

She inhales sharply, eyes flying open as she looks at him, and he can feel her heartbeat just under his hand as his fingers trail to her nipples, teasing at the dusky pink tips. Her nipples harden expectantly under his touch, just begging for his attention and he fights the urge not to take one into his mouth, she probably tastes just as sweet as she looks, he wants to fucking know.

He almost slips, mindless as her body is revealed to him, but some distant part of him knows he has to maintain at least some ridiculous semblance of professionalism. 

He cups the weight of her breasts in each hand, filling each of his palms easily, “They’re perfect Mika, so full and perky, do you agree?”

She nods bashfully, and Eren’s smile widens as he continues to play with her tits, testing the weight in his hands, fuck she definitely has the best rack he’s ever seen. He pinches at her nipples experimentally, curious at her level of sensation, and almost immediately she lets out a little whimper that goes straight to his dick.

“And so sensitive too,” he murmurs dazedly, god she’s perfect, “That’s so wonderful Mika, your tits are truly perfect.”

She says nothing, her eyes focused on the wall behind him, her cheeks pink and Eren tuts, “What do you say when someone gives you a compliment, Mika?”

“Thank you,” she whispers quietly, her eyes finally focusing on him and she smiles hesitantly.

“Do you believe it when I say it baby, is that the problem?”

She nods meekly, “I never realized how insecure I was about them until now.”

The silver of her eyes turns watery as she struggles not to cry, his perfect crybaby, “It’s just nice to be appreciated.”

Eren hums in approval, continuing his lavish exploration of her boobs, kneading the soft flesh lovingly, enjoying her every reaction, how just the slightest twist of her nipple can have her keening. 

“They’re perfect Mikasa, don’t ever hide them, not from me.” 

She nods, leaning into his touch, the warmth of his hands as he cups them in his palms, content to let him do as he wants, completely devoted to him.

“You know what,” he breathes, thumbing over one of her nipples, feeling it pebble up beneath his finger tip.

“What?” Mikasa whispers back, and Eren replies distractedly, already lost to his daydreams, “I bet they look so pretty when you’re getting fucked Mika.”

He can already imagine how they bounce with every thrust, how good they’d feel under his palms while he fucks into her, how easily he’d be distracted by them all the fucking time.

“Probably look even better if you were getting tittyfucked.”

Mikasa gasps at his lewd comment and he snaps out of it, fearful that she’s realized he’s really just a pervy loser playing at psychiatrist. But no, she’s flushed, all the way down to those tits he’s so obsessed with, pretty pink, the same colour as her nipples colouring her cheeks, her pulse throbbing against her neck, breathing coming just a little too fast.

“You like that huh Mikasa?”

She nods almost involuntarily, and Eren decides to cut it there, if this goes any further his plans are going to go up in smoke.

It takes great self-restraint to remove his hands from her breasts, to stop teasing at her nipples, watching all her sweet little reactions because she’s so fucking sensitive. He feels almost bad, leaving her cold and bereft of the warmth of his hands. She shivers when he pulls away, her shyness coming back as she immediately moves to cover herself, but he won’t let her go quite so easily.

He stops her before she can cover her breasts, trailing his hand along her sternum, he lovingly traces the impressive teardrop shapes.

Circling her nipple with his thumb, he gives her one last parting shot, something to think of before they go back to the boring parts of his plan, “Next time you’re feeling insecure baby, about anything, I want you to text me, send me a picture. I’ll be sure to tell you how pretty you are.”

She opens her mouth, as if to protest but Eren cuts her off, “Think of it as positive reinforcement.” 

It’s all fun and games until he gets a text at 11 pm of her cunt soaked with nothing but her fingers inside, desperate and needy and totally innocent because she’s just that fucking dependent on him.

Dr. Yeager am I pretty here too?

He’s going to hell for this one, Eren thinks, he’ll probably see Freud there. 

Session 8

"Good afternoon, Mikasa," Eren greets from his seat upon the entrance of his favourite client.

She looks particularly delectable today, dressed in a pair of high-waisted jean shorts and a tiny little tube top that barely restrains her perky tits.

He smirks as he leans back a little, happy he wore his tighter slacks today as his dick presses against the fabric at just the sight of her, let her look.

He knows he looks good as he looks over his glasses at his favourite patient.

She blushes, "Hi Dr. Yeager, sorry I had to reschedule earlier."

He brushes her off, smiling as he readjusts his glasses, "It's fine, I'll always make time for you Mikasa."

She beams, "Thanks, Dr. Yeager."

He used to love that title, but now he hates it, he wants her calling him his name, or better yet, something else entirely.

"So Mikasa, how have you been since our last session?"

She settles herself in the seat across from him, putting her purse down, her expression lighting up as she discusses her progress,

"I've been doing so well! Just like you suggested, I'm really trying to think about intimacy and relationships differently."

Eren nods along, happy their sessions have been working, that she's starting to open up a little more. When she'd first come she'd been so closed off to any future relationships, riddled with trust issues from an ex-boyfriend who liked to cheat too often and more daddy issues than he'd ever seen in his life.

"I've even been considering going on a few dates recently."

He curses in his head, he doesn't want it working too well.

He cuts her off slightly, "That's wonderful Mikasa, but I really think before you re-enter the dating pool that we have to deal with the root cause of the problem here."

She nods solemnly, already guessing at what he's talking about, "My daddy issues."

"No," Eren hums, "Let's not call it that, how about your lack of positive male role models."

Mikasa chuckles, shaking her head, more than comfortable with her own label, it's a recurring fight they have every session. She calls it what it is and Eren prefers more mild language, and not such a degrading label.

"Yeah, whatever Dr. Yeager, that."

"Yes, I'd love to discuss that today."

She nods, taking a deep breath as she centres herself for the session and Eren is quick to launch into what he hopes is the final phase of his plan, because god he wants her to stop calling him Dr. Yeager.

"Have you ever actually called anyone 'Dad', Mikasa?"

She shakes her head, "No, never. I mean with Levi, I got close, but you know he works in the military now, I never see him."

Eren nods encouragingly, "So it's safe to say you've never really had a positive male role model in your life that stuck around, someone to really commit to you."

She shakes her head sadly.

"I think that's really the root of your issues with commitment and intimacy, you've never had a man do that for you, so why would you feel safe committing yourself to a man."

Mikasa nods thoughtfully, "That makes sense, I was always really scared with Porco you know, and he told me part of the reason he cheated so much was because I never gave myself to him fully."

Eren fights the urge to scoff, what a load of crap. The kid was a narcissist for sure, he's sure he would have cheated on his patient regardless of if she had daddy issues or not.

"Yes, you fear commitment because no one has ever committed to you in the long run."

"Yeah," she sighs, "I'm not sure how exactly to fix that though Dr. Yeager."

"Well Mikasa, the solution starts with identifying the problem so you're doing a great job already, I'm so proud of you."

Her whole face lights up with his praise and he smiles right back, God this will be easy.

"Thank you so much Dr. Yeager."

"Of course Mikasa, as you know I think it's so important to recognize progress and you've been doing so amazing in our sessions, you've been such a good girl, I'm so proud of you."

She nods a little tearfully, "Thank you, that means so much."

He smiles at her as he takes his glasses off, uncrossing his legs and spreading wide, giving her a glance at his large form, let her look, he knows she thinks he's good-looking. Her body language gives it away every session.

"ON that note, I think a starting solution is actually for you to recognize others, men that you feel comfortable with, people you would consider calling Dad, Daddy, you know?"

"Like Levi?"

Eren hums in disagreement, "Not Levi."

Absolutely fucking not. Definitely not Levi, that's not who he wants her calling 'Daddy'.

"Someone you feel comfortable with, someone you talk to often, that you feel you can divulge anything to, someone you really trust, someone you'd feel comfortable calling 'Daddy.'"

"Oh," she murmurs, her brow scrunching up as she tries to think, "I don't think I really have anyone like that."

"It can be anyone Mikasa, just someone you'd feel comfortable calling 'Daddy', someone you could go to regardless of the situation, nonjudgmental."

Someone to whisper 'Daddy' to in the throes of passion while he fucks her into the mattress so hard she sees stars.

"Anyone?" Mikasa clarifies, looking at him a little too curiously, her eyes flicking over his form and Eren gets more comfortable in his chair, stretching out long legs and stretching his arms, stretching his white button-down across his chest.

"Anyone," he repeats, his voice infused with just an edge of the lust he feels.

She looks up at him shyly, "Even... even you?"

Eren allows a pleased smile to bloom across his face, "Of course Mikasa, I'd be honoured if you felt that comfortable with me."

"Then I choose you," she says bashfully, a shy smile on her face, cheeks tinged pink and god he's never been happier.

"Then say it Mikasa, test the word on your lips, see what it's like."

"Daddy," she murmurs and fuck now he's at full-mast in his pants, just the way she says it, such a pretty breathless sound, and fuck he can already imagine how she'll sound screaming it when he's inside her.

"In a sentence 'Kasa," he directs and fuck she's so submissive, so read to take orders.

"Umm," she gets slightly flustered and Eren whispers an example, "Daddy could you pass me a pen?"

MIkasa laughs nervously before repeating his sentence, "Daddy could you pass me a pen?"

He's quick to pull one from behind his ear, "Of course baby."

She takes the pen tentatively, looking up with a big smile before responding in kind, "Thank you Daddy."

He's so fucked.

Session 11

“Darling I’m worried about you,” her mother tells her over the phone, the concern in her voice real for once and Mikasa fights the urge to snap back. 

“I’m fine mother.”

Of course she’s fine, she’s finally getting the treatment she needs to heal herself, feels the best she’s ever felt, confident, beautiful, loved, appreciated. 

And it’s all thanks to Dr. Yeager. 

His sessions have improved her so much, her physical and even mental well-being showing so many signs of improvement. 

It’s amazing, how confident she feels in her body, even sexually, she feels charged, ready to go. 

Ever since that one session, she can’t stop looking in the mirror, can’t stop thinking about how reverently Eren had cupped her tits, how he’d felt every inch of her breasts, held them in his hands like they were weighted gold. She can’t get the starstruck look on his face out of her head, how his eyes had glazed over just slightly, slipping from emerald to a sleepy jade, adoring. Fuck, how he’d touched her, massaging her breasts with such gentleness, fuck. 

Her only regret is that he didn’t kiss her there too, and just thinking about his mouth on her tits has her breasts tingling. She’s felt amazing ever since, has started wearing low cut tops just so he can see them better, and it’s amazing because before she never would have worn something so revealing, not the v-neck bodysuit she’s wearing right now. 

But Mikasa remembers Eren’s words whenever she doubts herself, ‘Show them off, don’t ever hide them’, how intently he’d said it, the finality in his tone that left no room for her to doubt herself. Eren was completely supportive of her.

Her mom on the other hand would call her a whore if she could see her, and Mikasa thanks god they’re not video calling right now.

Her mother drones on in her ear and Mikasa can’t help but be resentful. Here she is, feeling the best she has in years since business school, finally getting help, and her mom is hounding her about her every move.

It’s infuriating. The woman who’s barely given a shit, done the bare minimum required to raise a child is now finally worried about her. She’d spent Mikasa’s childhood jet-setting off to far away countries and remarrying far too many times, and now when Mikasa no longer wants her attention, she’s finally interested. 

“Mom, I’m really fine, can we just stop discussing it?”

She can practically feel her mother’s eye roll on the other end of the line, “Young lady, if you continue to take that tone with me I’m going to hang up.”

“I’ll do you one better,” Mikasa responds and before her mom can say another word she’s clicking the bright red ‘end’ button on her phone and it’s finally over.

She sits outside Eren’s building for a moment, taking deep breaths in her car, her beloved red mini cooper. She just needs to breathe, inhale, exhale before the panic sets in, before the fear of the repercussions because she just hung up on her mom and she knows the shit storm that’s going to come afterwards.

Levi will call, her mom will call again, everyone will berate her, she can hear the lecture already, ‘where is the respect?’. They’ll probably get stepdad number five involved, and it’s too late, the panic is already setting in, her vision going spotty as the world begins to blur around her. 

She just needs a moment, just one second, just needs the safety, the calm, needs the peace she’d had before she’d picked up the phone, Eren, she needs Eren. 

Dr. Yeager, no one has ever made her feel safe like him. 

Blearily, she makes her way into his office, barely remembering to lock her car, bypassing his receptionist without a word. 

She staggers into his office, barely feeling like herself, an out of body experience, until finally she sees him, sets eyes on his handsome face and suddenly it’s all okay.

She collapses onto his love seat in relief, the scent of his office comforting, familiar, the faint smell of leather and essential oils wafting from his diffuser, because as he says, he’s a therapist, his office should be calming. 

“Mikasa?” He questions, and his voice is like a balm to her psyche, the rich timbre vibrating to her very core, she practically melts into the couch, already at ease.

“Are you okay?” He asks, and suddenly he’s above her, crouched down next to her on the couch, checking her temperature with the back of his hand, a concerned look marring his pretty face. And really, he’s so pretty, even today, a Friday when he’s more casual, slightly dishevelled from the week he’s had. Unshaven, stubble coating the line of his jaw, his tie loose, like he’s been tugging at it. 

She can’t answer him, too absorbed in his presence, admiring him as his glasses slip down the bridge of his nose, green eyes filled with nothing but concern, how his hair is swept over his eyes, exposing his undercut and the lone piercing in his right ear.

“Miki,” he hums, his hand slipping down to cup her cheek and she leans into it, enjoying the warmth of his hand, the rough callouses of his palm. 

A relieved smile lights his lips as she finally reacts, “Baby, don’t scare me like that, I was worried.”

“Mmm,” she turns her cheek to press her lips against his palm, just barely a kiss, not enough to incriminate her if he were to say anything, “I feel better now.”

“Good, were you having a panic attack?”

He slips effortlessly into his role and Mikasa mourns the loss of her casual Eren, the brief glimpse she’d had of him. 

“Yeah,” she mumbles in embarrassment, “It was my mom.”

“You know how I feel about your level of contact with her.”

Mikasa deflates a little, she knows, Eren has been encouraging low contact for weeks now and with her reaction just now, she can’t say she disagrees.

“But she’ll worry if I stop.”

The rough pad of his thumb traces her cheek bone lovingly, “But baby this is what’s best for you, for your mental health and that’s what’s important here. Remember that okay?”

She nods, but already Eren is getting up, leaving her without his touch. She feels lonely, bereft as he takes his seat across from her, so far away when more recently he’d been sitting on the love seat with her for every session. 

She resists the urge to pout, trying to maintain her dignity. 

Eren looks disappointed as he grabs for his notepad and Mikasa can hardly bear it, she hates to disappoint him.

“I promise I’m trying, it’s just really hard Dr. Yeager.”

He looks up at her sharply and she quickly corrects herself, the new title rolling off her tongue with reverence, “Daddy.”

He nods approvingly, writing something down in his notebook before settling into his chair, spreading his legs wide, exposing ever inch of thick thighs and the obvious line of his dick.

“I’m not going to make you do anything you don’t want to Mikasa, but seriously consider how your mother’s presence in your life seems to affect you.”

She nods morosely, he’s not wrong, but she’s not entirely ready to cut out her mom just yet.

“Can we talk about something else?”

He nods, “Of course, how about we pick up where we left off last session?”

Mikasa nods eagerly, “Yes, daddy.”

Eren gives her a fond smile, “Do you like saying it?” 

“Yeah, it’s nice to finally say, I like it.”

Eren is nodding, continuing to write something in his notebook and not paying her as much attention as she’d like, so before she can stop herself, her next words slip out, “I get why the girls are always saying it in porn.”

Eren lets out a startled laugh, shaking his head at her fondly, “Yeah, it’s a pretty common thing.”

Usually she’s more reserved than this, doesn’t let herself be so bold, after all Eren is supposed to be her therapist, strictly professional, but she can’t help it, “Does anyone, does anyone ever call you that during sex?”

Eren hums in contemplation, “Sometimes.”

He’s quiet for a moment and Mikasa deflates, she just wants to know if she’s special, if he’s even remotely interested, considers her more than a patient at all, more than some pathetic charity case Armin had pawned off on him.

“Depends on the girl though,” he says after a pause and Mikasa looks up to see a wicked smirk carve his lips, his tone suggestive, “For you Mikasa I think I’d tolerate it.”

Her heart skips a beat as he looks at her over the rims of his glasses, those eyes flashing dark, mischief, promising trouble. But just as quickly as it appears, it’s gone, Eren returning back to her ever professional therapist, “So your relationship with your mom, you’re going to cut her off right?”

“Yes daddy.”

Session 13

Mikasa tempts Eren in ways he’s never dealt with before. On every level she’s a tease, sent from hell just to torment him and today is no exception.

She waltzes into their session in a pair of long flowing dress pants that accentuate her waist and are glued to her ass in a way he knows means she’s not wearing underwear, her tits just barely concealed by the deep V of her navy bodysuit. 

She’s dressed appropriately for work, business casual but just fucking barely, one little slip of that bodysuit and he’ll see the blushing bud of her nipple because she’s not fucking wearing a bra either. 

But then, as if to add insult to injury, ten minutes into their session she asks, and derails his entire train of thought, all the progress he’d been building towards her letting him fuck her, she throws it all out the window. 

“Daddy, umm do you think if I’ve made enough progress that I could maybe try and go out with Colt tonight? He asked me but I thought I’d get your okay.”

Apparently, the progress Eren had thought they’d been making was actually progress towards her fucking Colt, her new coworker, the dreamy prince charming she wouldn’t shut the fuck up about sometimes.

Shit, this was not what he had planned for and Eren fights to keep the calm expression he has on his face, unphased, “Of course baby, I don’t see why not. If you feel you’re ready for that level of intimacy, of course.”

“Thank you,” she replies, relieved, “I’m so excited about it, it’s been so long. At this point, I’d love just for a kiss even.” 

Eren’s nails dig into the fabric of the recliner as he struggles not to rebuke her, he’s the only one she should be receiving kisses from and they haven’t even done that yet. He’d thought they’d been making progress, thought after cooing over pictures of her pretty cunt, holding her fucking tits in his hand, calling him fucking ‘Daddy’, that she’d realize he was the one she should be moving towards intimacy with. 

But apparently not. 

Mikasa beams at him, woefully innocent as she chatters about her excitement over the date, overanalyzing what she’ll wear, how she’ll act, if she should let him fuck her. All the while Eren fumes, and he schemes, because apparently his plan isn’t so perfect after all, his star patient is going down the wrong path. 

He’s fed her a steady diet of carefully curated porn, delicate girls being properly fucked by men with big dicks, pounding them into the mattress, against the wall, just like they deserve, he knows it must be getting to her. How her eyes glaze over just slightly when she sees his muscular form clad in a tight button down and slacks that mould to his legs, how her eyes are always drawn to the heavy line of his dick in his pants, she’s so fucking obvious. 

It had all better be worth it. 

He’s going to have to speed up the process. 

Mikasa sits primly over her nice dinner, waiting for Colt to come back from the washroom. The waiter has dropped off the check and it’s time. The bill is paid, courtesy of her very lovely date and now she knows she should go back to his apartment, reward him for his chivalry. 

Some deep part of her wants it, especially with how keyed up she’s been lately. Masturbation doesn’t do it for her anymore, all the porn Eren has had her watch, it’s nothing compared to the real thing now, she needs it, has spent far too long imagining it, being fucked again. It’s all she wants.

Her phone pings with a notification and she’s quick to distract herself, picking up the phone, she smiles as soon as she sees it’s Eren’s number. He’s probably worrying over her, wondering how her first date went.

But as she opens up the conversation, it’s not that at all, no, instead it’s a dick pic. She’s already salivating over the image, thick and heavy, and the length easily passing his belly button, up, up, up. And she knows it’s Eren, it’s so obvious in the way he holds his dick, grip rough, just like him. The slight scars along his knuckles she’s memorized, wondering where he got them from all the way to the watch he’s wearing, his signature Rolex, and fuck he looks hot. His hands so big, but even they can hardly grasp the heavy girth in his hands. Mikasa knows she could probably barely wrap her fingers around it, the crisscross of veins along the underside to the weepy pink tip. 

She feels like she’s overheating. 

To her delight his first text is quickly followed by a video, and this time she gets to see him in action, the way he fucks his hand with such wild abandon, the sounds he makes, harsh grunts and quick breaths as he gets close, only to spill all over his hand, white-hot spurts of his seed. He cums so beautifully somehow, painting the hard lines of his abs with streaks of white, his fingers sticky with his seed, fuck. 

Mikasa thinks it’s a travesty that it all goes to waste, her heart pounding because what if that was her instead, she wouldn’t let it go to waste, would suck him off till he came down her throat. A dick like that deserved to be swallowed and she can barely concentrate on anything but her phone.

By the time Colt comes back to the table Mikasa has worked herself up so much her fingers have unconsciously slipped under the hem of her dress, comforting touches to her pussy as she tries to sate herself for the moment.

“You ready to go Mikasa?” 

She looks up at him, such kind eyes, the perfect boy for her, but all she can see is how he doesn’t measure up, how he’s not Eren, not Daddy. A text chimes in, and Mikasa spares it a glance before replying to Colt, her heart constricting in her chest at the message. 

Sorry baby, those were meant for someone else, have fun on your date ;) 

“I’m actually not feeling so great Colt, I might just catch an uber back to my apartment if that’s okay?”

His face falls for a minute, and Mikasa feels bad but she can’t go with him, not like this, she barely feels in control of herself, she needs to call Eren, to hear his voice, talk to him, something.

As soon as she’s in the Uber she tries, but all her calls go to voicemail. Her head is pounding with the idea that he’s with someone else, ignoring her in favour of sexting some skank, blood pressure through the roof.

And yet, the most reassuring part of it all is that Eren never deletes the pictures from their chat, doesn’t even bother to ask her to. He just lets her keep them, her hoarded treasures, an up close shot of his dick and a video of him jerking off.

But Mikasa will happily accept them, if that’s all she gets for now, it’ll have to tide her over. 

Session 14

“So why didn’t you sleep with him?” 

Eren asks almost immediately, before she’s even told him about her night and she shrinks under his scrutiny, he knows her so well.

“I just, I wasn’t comfortable,” she lies, “I was nervous.”

Eren looks pleased at her admission, a smile crossing his face briefly but it’s gone in an instant before she can be sure it was there at all.  

Eren nods, “I see, were you worried about your umm performance?”

She shakes her head, thinking on the question, “Maybe a little but I just didn’t think I was ready Daddy, I think we need more sessions.” 

At this, she gets a real smile and he pats her knee approvingly, “Of course Mika, I’m glad to see our appointments are having such a profound effect.” 

She beams, “I feel like a new woman.”

Eren coos at her in agreement, “You’re perfect baby, my best patient.”

Mikasa basks in his praise and approval, her head feeling light, her heart pounding against her chest at how she’s pleased him, she’s his favourite. 

“So you felt uncomfortable?” Eren asks tentatively and Mikasa nods, “It just didn’t feel right to go home with him Daddy, and I was umm,” she blushes, trailing off as she tries to figure out how to word it.

“Yes?” Eren prompts and Mikasa wrings her hands together nervously as she fights to get the words out, “I was already thinking of you Daddy, I mean umm after the-” Mikasa stumbles over her words, unsure what to call the accidental texts Eren had sent her, would it be correct to categorize them as dick pics? Should she just call them pictures? She doesn’t want to make Eren uncomfortable.

“Go on sweets,” Eren encourages, “The pictures I sent you, the ones of my cock.”

Her breath hitches in her throat as she listens to how his voice wraps around the word, obscene, dirty, and she wants it whispered in her ear, fuck.

“Yes, those ones.”

“Say it,” Eren commands, and when she looks up, his eyes are shaded dark, hungry, like a predator and she responds before she can even think about it, “The pictures of Daddy’s cock.”

“Yes,” he breathes, “Go on Mikasa, what were you saying, you were thinking of me?” 

She nods eager to continue, “I was thinking of you and I umm, I didn’t want to disappoint you, I know you said I should be taking things slow, so I stopped, I went home.” 

“Oh baby,” Eren whispers, almost involuntarily, his eyes glazed slightly, “You’re such a good girl.”

She smiles at him genuinely, feeling more confident now that she has his approval. 

Eren releases a long breath, and it feels charged, like one wrong move and he’ll snap, and maybe she wants him too, she’s not sure.

It’s quiet for a moment and Mikasa holds her breath, waiting, waiting.

But when he looks up, his green eyes are clear again, as a spring day, and Mikasa wilts as he regains his control, ever professional Dr. Yeager. 

“That’s so great to hear Mikasa, I’m glad you were able to maintain control, but I have to apologize again, I’m so sorry about those pictures last night Mikasa, those were meant for the girl I’ve been seeing,” Eren says, coming back to himself.

“No it’s fine,” she deflates slightly, they were meant for another girl, “Please don’t worry about it.”

She doesn’t want him to prod too much on the topic or he’ll realize she’d kept the pictures, might ask her to delete them and she doesn’t want that.

“It’s really not, I apologize, I got your numbers mixed up. I hope they weren’t too much of an inconvenience, that they didn’t interrupt your date.”

“Not at all,” Mikasa lies, “Please, don’t worry about it.” 

She bites her lip as Eren shuffles some papers on his notepad, flipping the page as he prepares to go back into therapy mode, probably continue to grill her about the date, but Mikasa doesn’t want it to end just yet, “You umm, you have a really nice cock Dr. Yeager.”

“Daddy,” she corrects herself, before he can correct her and she waits with bated breath for his response, she’s crossed the line so many times today and yet she can’t stop herself, her chest filled with butterflies as she waits for his reaction. 

He looks caught off guard, a reluctant smile coming over his face, a refreshing change from his previously serious expression, and he chuckles. It’s like a hit for her, that smile, the timbre of his laugh, how those eyes light up with approval. 

Her eyes are drawn to his hand as he almost instinctively cups himself over his slacks, proud, bunching the fabric up just enough so she can see the shape of him, just a taste of what she now knows hides under those pants. Her mouth waters at just the thought, he has such a nice dick, she wasn’t lying, a pretty cock, the tip a weepy pink. He's long enough that she knows she’d feel it deep in her guts, and thick enough that she’d probably be ruined for other men, have trouble walking the next morning, his place carved out inside her. 

“I know,” Eren replies, his voice gravelly and Mikasa squeezes her thighs together impatiently, his words going straight to her core, he’s so fucking confident. She loves it, knows he’d give her the night of her life. 

Eren makes a humming noise, choosing not to acknowledge her blatantly inappropriate compliment any further, instead choosing to move on, or so she thinks.

“Mikasa, can I ask you a question?”

“Of course.”

“How did you feel when you received that picture yesterday?” 

She’s startled, unsure how to respond but Eren presses on, “Did it turn you on?” 

“Yes,” she whispers shamefully, her response quick this time, the truth pulled from her, “I’m sorry.”

Eren is quick to soothe her, his hand moving to cup her knee, “It’s okay you have nothing to be embarrassed about, it was an accident but it was actually a good test.”

“Really?”

“Yes, it’s perfect, I know it’s been a while since you’ve had real stimulation other than porn and clearly nothing happened with Colt, so tell me Mika, did you enjoy feeling that way?” 

She squirms in her seat, thighs pressing together to repress the ache, the delicious heat licking at her centre, “I loved it, I’ve missed it so much Daddy.”

“Of course, sweetheart, I know you must have missed it.”

“So much,” Mikasa whispers breathlessly, the reply just slipping out, a plea.

The hand on her knee begins stroking up, long soothing motions that have her melting with little effort, “I understand love, I’m sorry I’ve deprived you for so long, c’mere why don’t you get more comfortable.” 

She goes to him easily, it’s so normalized to her now, sitting in his lap during their sessions, it’s warm, comforting even to be so close. She’s so starved for attention, for intimacy, she’ll take whatever she can get. She’s more than happy for it to be his calloused fingers palming over the curve of her ass, murmuring sweet nothings into her hair while she babbles about her mundane problems.

She’s blessed that Dr. Yeager had even taken her on as a patient, she feels so lucky.

“Daddy,” she whimpers pathetically as he takes her into his arms, like she weighs nothing, she cuddles right in, this is where she belongs, snug in his lap.

He brushes a kiss over her forehead, “I’m here Mika, baby.”

She melts into him, allowing him to do as he likes, re-situating her so she’s facing him, her thighs parted over his thick frame, straddling him on his chair, the heavy bulge of him pressed right against her core. 

Her hands toy with the buttons of his shirt nervously, they’ve never been in such a position before, so obvious, but she’s loving it, can barely resist pressing herself closer, feel him more. Her brain is already mush with images of what would happen if she were naked right now, riding him in his office, the lewd noises as he fucked into her, how his secretary would probably hear. How the little bitch would realize she has no chance, that it’s Mikasa who’s getting fucked. 

She doesn’t want there to be any distance, wants to forget where she ends and he begins, needs him so desperately, and before she realizes it, she’s rocking into him, just unconsciously, enjoying the friction against her cunt, the button on his slacks bumping against her panties deliciously in her tiny little t-shirt dress.

She regrets wearing panties at all. 

“Sweetness,” Eren startles her out of her trance, calling her attention up to his face and Mikasa hums in response, capable of little else. 

“I think I have an idea of why you couldn’t have sex last night.”

She cocks her head at him, wondering if he’s figured her out, fuck she hopes he has.

“Why?”

He leans in, so close they’re almost forehead to forehead, she can almost feel the rough of his stubble tickling against her cheek, smell the gum on his breath, mint, wintergreen.

His hands settle on her hips, pressing her closer, just slightly, “You’re out of practice baby, how long has it been?”

She gasps at his unexpected assertion, he’s not exactly wrong, but he’s also not right.

Her hands turn to fists in the silken fabric of his shirt while his own dip down the curve of her waist to cup her ass. 

“A few months at least,” she breathes and Eren grunts, pleased with her answer and she can feel the vibrations under her fingertips. 

Oops, one of the buttons of his shirt comes undone, but she can’t find it within herself to care, not while his hands are fondling her butt, and the planes of his chest are exposed, his collarbones, his pecs, the sliver of bronzed skin, she desperately wants more. 

He tilts his head down, nosing at her cheek, stealing her breath as he speaks, so close, just a hairsbreadth from her lips, she can practically taste him, the softness of his lips, the mint of his gum. 

“In my professional opinion,” he murmurs, his eyes intent on her lips, his words whispering against her cheek, “I think you need to get used to it again, the intimacy I mean.”

Mikasa nods, her nose bumping against his, pressed so close together, she needs a kiss, craves it, and finally Eren’s eyes slip up to her own, dark evergreen with lust.

“I think you need practice, Mika, you need to get used to it.” 

Her eyes flutter shut as she waits desperately for him to close the distance between them, she wants it so badly, needs his touch.

“I could help you,” Eren offers charitably, his hands rubbing soothingly up and down her back, slipping effortlessly under the fabric of her shirt so she can feel the warmth of his palm, his other resting comfortably on her ass, teasing at the waistband of her jeans. 

“I dunno if you can feel me Mikasa,” he intones against her cheek, pressing her more harshly against him to feel every inch of his impressive cock, “But I’m pretty big.”

She considers it for a moment, as if her brain isn’t screaming yes, her cunt soaked with arousal, hot through her jeans, just begging to have him inside her. 

“If you can take me Mika, you can take anyone,” he rumbles, one last little push and Mikasa falls over the edge willingly.

“Yes Daddy, thank you, that would really help.”

Her words are distant, far off, and already Eren is unzipping his fly. 

She can barely contain herself as he undoes his slacks just enough to showcase a pair of blue boxers with a very obvious tent, fuck she wants it.

He chuckles at her laser focus, and Mikasa looks up, pouty. Is he making fun of her?

“Baby you have to take off your pants too.”

“Oh,” she murmurs, moving to undo her jeans, but his hands are already tugging at the button, his thumb caressing over her stomach, teasing at her belly button ring. 

She lets him takeover, she feels so relaxed, dropping her head to nestle against his shoulder, listening to the beat of his heart interwoven with the sounds of her zipper coming undone. 

Her breath hitches when he finds her panties, deft fingers quick to sleep under the lacy garment, and she’s so thankful she’d worn the pretty blue ones today, the thong she hasn’t had use for in forever. 

“Fuck,” Eren curses above her as his fingers meet smooth skin, her pussy shaved bald just in case, because she’s sure Dr. Yeager likes things pretty and pristine, just like his meticulously kept office, his usually impeccably shaved beard. She’s noticed her therapist has just a touch of OCD, and it all works to her favour, because the first touch of his fingers to her delicate mound is like heaven.

She’s so sensitive, it’s been so long, his fingers mapping out the dewy folds of her cunt and of course he finds her soaked and wanting.

“Oh baby you’re so wet,” he groans, almost in a trance as his fingers move to find her clit expertly, rubbing soft circles at the sensitive bundle of nerves. Already Mikasa is in heaven, her hands fisted in the fabric of his shirt for purchase, barely able to respond because he’s right, she’s so ready, it’s been so long.

“I’m sorry I made you abstain for so long baby, it must have been so hard.”

“It was,” she whines, delirious already and even more so when he slips a digit inside, and his hands are so much bigger than her own, it feels nothing like when she touches herself at home. 

“Don’t worry Mikasa, Daddy is gonna make sure you can get back out there, get you comfortable with intimacy again, now why don’t you sit up for me sweetheart so we can start?”

She obeys him easily, desperate for his cock, and she knows the stretch will hurt especially after so long without it, but she also knows it’ll be so deliciously painful, fulfilling.

She’ll be whole again, full of him, and the idea is intoxicating. 

She sits up on her knees, watching almost obsessively as he frees his cock from his boxers, still mostly clothed, the thick of him jutting out from a well groomed patch of hair and fuck he’s even bigger than she thought.

He gives himself a couple experimental strokes and Mikasa can’t help but think how much prettier it is in person, the shiny beads of pre slipping from the tip, the crisscross of veins running down the underside. 

She lets out a little involuntary whimper as she looks him over, her hands slipping from his shoulders unconsciously for a touch, she just wants a feel but Eren bats her away. 

When she looks up he’s smiling, “You want a touch sweetheart?”

She nods desperately, she needs to feel it in her hands, it’s been so long. She’s always had a bit of an oral fixation, Porco had thought it was weird, but sometimes it was just nice to hold, to touch, to suck someone off, and with Eren’s dick, she can barely contain herself.

“How about another time sweets, for now we have work to do, we need to get you accustomed to the feeling again.”

Eren works her jeans off, and quickly slips her panties to the side, not even bothering with taking them off, and it feels dirty, hot. How he’s almost fully clothed, his dick laying hard against his stomach, staining his button down with pre, while she’s lost her pants, wearing little but her panties and her pathetic t-shirt. 

His hands find her thighs, and before she knows it, it’s happening. Eren barely bothers to prep her, she’s so wet for it, arousal dripping down her thighs, he gives her no time to second guess herself as he positions her over his cock.

Her cunt spasms as she looks down, the sight so erotic, the heavy jut of his cock so close to where she needs it, just inches away, if she dropped all of her weight right now he’d slip in so easily, she knows it, bullying his way inside. 

However, Eren goes slow, teasing her with the thick head of him, tapping against her clit, wedging between her swollen lips, but never doing more.

“Eren,” she whimpers desperately as he slicks himself up with her arousal, easily slipping through her folds.

“Manners baby.” 

“Daddy, please?” She begs, her hands clenched around his bicep and finally, finally he gives her what she needs.

It’s slow, and he stretches her out so much more than she thought he would, pressing his way inside her, slowly impaling her on his cock. 

She’s a slump in his arms, can barely hold herself up, she’s so unbelievably full, has never felt like this before with anyone else, no matter how healthy the relationship. 

It’s almost a relief once he’s inside her, her insides welcoming him gratefully, like he was meant to be there, to carve her out. She clings to the nape of his neck as he inserts the full length of him, he wasn’t joking he really is that big. She knows he was right, no other man will ever hold a candle, will ever be a problem because she’s taken him, every single inch, his balls pressed against her ass, their hips meshed together. 

He bottoms out easily, the blunt tip of his cock bumping against her cervix, and oh she was right she can feel him in her guts, knows if she were to press at her stomach that she’d feel the bulge of him inside her. 

She holds onto him for dear life, just basking in the feeling of it, how each little movement sends sparks of pleasure shooting through her. 

“How’s it feel Mika?”

“Good,” she whimpers as he moves slightly and she can feel the line of his smirk on her neck, “Nice to have a dick inside you again?”

“So nice,” she sighs out, euphoric. 

It takes her a few minutes to adjust, just having him seated fully inside her, how nice it is to have sex again, just the steady beat of his heart against her own, his laboured breathing in her ear.

“You can move now,” She whispers against his ear, dropping just the smallest of kisses against his neck, he deserves it for being so sweet, such a good therapist, she’s never felt this good in her life, this sure of herself.

“No Mika, I can’t, we’re gonna stay just like this.”

“What?” She grits out desperately, she feels like she’s going to die if he doesn’t move soon, her oversensitive cunt begging to be used, to be fucked by this monster of a man. She craves a proper orgasm, knows he’d ruin her, that she’ll feel it deep tomorrow morning, wake up with the delicious ache of him inside her. 

He massages her hips lovingly, the vivid emerald of his eyes wicked, cruel as he smiles at her, “Well I’m not going to fuck you baby, that would be unethical, I’m just reminding you what it feels like, exposure therapy.”

He makes her sit like that, for the rest of the session, impaled on his cock, tsking her every time she tries to move, tries to find the friction she needs, and she ends up a sobbing broken mess in his arms.

“Daddy,” she whines, tears slipping from her eyes as she sits, her weepy cunt stretched around his dick, oversensitive.

“Shh sweetheart, just stay there like that, sit pretty on my cock, appreciate the feeling. Daddy has to write some notes on our session.”

Session 15

“So Mikasa, how did you feel after our session last week?”

He watches in amusement as she struggles to find words, her face pinching up at the memory.

He’d left her desperate and wanting, her panties soaked with her essence, painfully unfulfilled. She’d looked so pretty leaving the office, her outfit rumpled, hair a mess, cheeks permanently coloured pink, and the desperation in her eyes. How she’d lingered in his doorway after, looking like she wanted to say something, eyes sparkling with arousal, desire that he wouldn’t allow her to act on.

“Go on baby,” he’d sent her off, “I have other clients to get to.” 

She’d left the session looking a little more upset than he’d intended.

She’d even rescheduled this week’s session once and Eren had worried that he’d pushed her too far.

But now, as she sits across from him he realizes he’d worried for nothing, of course she’d come back. He’s basically trained her into it.

“It was good,” She tells him vaguely and Eren quirks an eyebrow at her lack of detail, just good? 

He says nothing and Mikasa takes that as her cue to continue, “I just, I needed it so much Daddy but I couldn’t cum, I was so desperate.”

“Of course baby, I'm sorry about that you deserve to have an orgasm too but it wouldn't be right, you're my patient."

She nods in acceptance, looking defeated and Eren is quick to bring her back to him, "Did you touch yourself when you got home?”

“Yes,” she confesses shyly and Eren is so pleased with her, she couldn’t be more perfect if she tried. 

“Did you feel better after?”

She nods earnestly, “It felt so good Daddy.” 

“But?” He prompts and Mikasa slumps into the couch, “But I couldn’t cum, it wasn’t the same as having you inside me.”

“Of course not, nothing can compare to the real thing Mika,” he scoffs and she deflates even further into the couch, ashamed. 

He hums, “I can tell you’re a needy little thing, need to be fucked well and often.”

She perks up slightly, nodding in agreement, he knows he’s fucking right, it’s what had been missing in her last relationship, he’d bet her douchebag ex could have kept her a lot longer if she was sexually satisfied.

“Is that a bad thing? Is it because of my daddy issues?” 

“No darling it’s not a bad thing at all, it just means you require a little more attention than most and some men are more than happy to provide it.”

Some men like him. 

“You just need a firm hand is all, tell me how are you feeling today, do you need it again?”

She tears up, breaking down in front of him, “Yes Daddy, I need it so much, I need to cum.” 

He smirks, “Then come here darling, today I’m going to make you cum, so you can remember exactly what it’s like, how much you need it."

Mikasa’s always been pretty, since she first walked into his office all shy and telling him she was Armin’s friend. 

She’s always been fucking pretty, and every session is a test of his restraint not to bed her over his desk and see just how pretty she can be.

But truly, nothing is prettier than her in the throes of orgasm, completely at his mercy. 

He’s been edging her for probably a half an hour now, milking every moment of the session she’d scheduled and cursing the fact that he has another appointment afterwards.

She’s completely naked, her pretty matching bra and pantie set discarded soon after he’d proposed that he give her some relief from her sexual frustration.

And now here she is, nude in his arms, her nubile young body his to control, like an instrument he’s an expert in.

She’s so fucking sensitive, even more so than he first thought, just sucking at those pretty tits had her keening as soon as he’d had his first taste.

And of course, she was just as sweet as he’d thought, like fucking candy. 

Her eyes are pale now in the light, a soft dove grey, glazed over with orgasm.

He’d rewarded her tenfold for sitting on his cock like such a good girl last session, has lost count of the number of times he’d made her cum.

He’s too busy basking in the sweet little noises she makes, how she likes it when he thumbs at her clit and sucks at her nipples at the same time. Learning all the little things that make her tick, how she likes three fingers not two, prefers to be as full as possible, enjoys the stretch, the pleasure balanced with the pain.

That she has an oral fixation, will happily suck on his finger if she wants, would probably adore choking on his cock, she’d licked her essence from his fingers with such gusto he’d barely restrained himself from forcing her to her knees right then. 

She’s everything, and he’s even more obsessed with her as she cums again from nothing but a brush to her clit, so sensitive and overstimulated it’s easy now.

“Oh Miki baby you’re so pretty,” he whispers and she gives him a sleepy smile, “Thanks Daddy.”

It’s in that moment, that he decides he’s going to give her fucking everything, and she’s never going to belong to anyone but him. 

Session 17

"Daddy-- I mean Dr. Yeager," Mikasa corrects herself and Eren smirks, god she's so easy, so obedient, knows how to be a good girl.

"Where are you going?" She finishes tentatively, it’s the end of their session and it’s evident she doesn’t want to leave, wants just a few more minutes and Eren struggles with his next words, hoping they have their desired effect, "I have a date."

"Oh," it's soft and defeated and god he loves how forlorn she sounds.

"Yeah, so I have to head out, sorry I’d love to extend the session but I can’t be late.” 

"Oh I don’t want to keep you I’ll um, I'll see you in our next session then I guess."

"Of course," He stands up, courteously reaching out a hand to help her up. 

She takes his hand gratefully, and even her hands are so pretty, delicate and manicured to perfection, but all he can think about is how they’ll look so pretty wrapped around his cock instead, clawing down his back because he’s fucked her too hard. 

He shakes his head a little, startling himself back to reality. 

“Actually, it’s been a few sessions since we last discussed Colt, how is that going?” He asks in passing, under the guise of curiosity but really, he just wants to know if the little thing has continued to abstain, his dick the only one she takes. If their appointments have been enough to tide her over or if she’s just that greedy, just that needy for it that she’d caved. 

It had been a risk to take her that day, let her warm his cock while he pretended to write notes about their session, the sweetest kind of torture. He’d given her what she’d been craving, missing from her life, but now he’s worried it’s backfired, that she’s been seeking gratification elsewhere, that he hasn’t been enough for her. The only reason he hasn’t properly fucked her yet is his desire to maintain some pathetic excuse for professionalism. 

But he’s hoping today he can push it farther, she just has to let him, she needs to be the one to do it, to push it past the bounds of therapy. 

Mikasa stumbles over her words, surprised at the abrupt topic change and struggling to come up with something that'll satisfy him.

"It's okay."

He frowns, tugging her up from her seat rather abruptly, "You're not happy?"

He fucking hopes she’s not happy, she’d better not be seeing him at all. She’d fallen apart on his tongue last week several times, and Eren has it on good authority that he’s brilliant with his mouth, she shouldn’t need anything more, the little brat should have been satiated. 

Mikasa makes a little ‘oof’ sounds as she stumbles into his chest with the momentum, falling into him. 

Her hair is ruffled as she tries to compose herself, her answer honest, "I don't know we went out again. But I feel like I just, I don't know what guys want anymore, it's been so long. I know we have our umm sessions.”

Her cheeks flush pretty pink as she recalls their time together, “And it's so helpful, really Daddy thank you. But I umm I still feel so inadequate, and before you say anything," she holds up a finger to stop him, "I know it's not me, I know I'm great, I guess I'm just struggling and a little afraid of the dating pool."

Eren hums, urging her to go on and as usual she doesn't fail. 

"I guess, I'm asking what guys want these days, I feel like there’s some unspoken expectations I can’t live up to."

Eren chuckles, "Well as your therapist, I'll say you're perfect just as you are Mikasa, and you don't need to change yourself to fit into the current societal mould of what women should be like to get a date."

"But?" Mikasa prompts and Eren grins, "As a man, I want my dick sucked."

Mikasa gasps at his unexpected answer and he laughs, "I want a good girl of course, nice, sweet, just like you. But I also want a girl who's obedient, who knows what I need, can help me relax you know," he continues, slipping the final nail in the coffin,"I get tired after a long day and my job is just so demanding, I'm exhausted."

"Of course, you need a break Daddy."

"Yeah, Daddy just wants to go home and get sucked off while he watches TV."

Her cheeks are lit pink and fuck does he hope she gives into this sooner rather than later, there's only so long he can play this game.

"I umm, is that what you're gonna do on your date?"

Eren shrugs, "Maybe, depends on the girl, it's a blind date, I'm not sure if she'll measure up you know. Not all girls can be like you Mikasa."

She gasps slightly, a sweet little noise and fuck come on Mikasa, give him something to work with here, some little hint that he can invite her back home.

"Yeah, well, I mean, I'm pretty great."

"You are,” he agrees, and he’s fucking begging here, he wants so badly to blow off his date for his favourite patient, c’mon Mikasa. 

"So ugh, you don’t know much about this girl?”

Eren shakes his head, leaning back against his desk, taking her with him slightly as he leaves their hands interconnected, mindlessly playing with her fingers. 

“Well, how do you know she’d be a good match?” Mikasa asks confrontationally, and he can see how she’s getting huffy, competitive.

He can’t help his smile, teasing her, “You want only the best for your favourite therapist?” 

“I just think it’s a risk, what if she’s awful.”

Eren shrugs, “I don’t really have a choice, I’ve been really pent up lately Mika, your case especially has been on my mind and I just want to relax tonight.”

She bites her lip, pretty white teeth nibbling at her full bottom lip, smearing her gloss around and Eren wants to bite it for her. He’s just fucking waiting, she needs to be the one to do it, to propose what he needs.

“I see, I didn’t realize I was taking such a toll on you.”

He brings her hand up to his lips for a brief kiss to her knuckles, “Of course not baby, you’re not a burden, but tonight I just need to chill out, get my dick sucked by a pretty girl, maybe fuck her if I feel like it.” 

Her breath hitches and he can see how she’s melting, he’s begging her with his eyes, just fucking ask. 

And finally, through some sweet merciful god she grants his wish, “Well, I mean, what if I could help?”

“What do you mean?”

“I think maybe I could help you relax, you know after all, it’s my fault you’re feeling like this.”
 

He drops his head in relief, bringing her hand up to his cheek for a kiss to her palm, fucking finally, he really wants his dick sucked.

“Oh, that would be wonderful, baby.”
