Work Text:

“Are you sure you're okay?” Sienna's voice is filled with concern, and while a part of him fills up with warmth, the other part curses himself as he holds back another yawn.

It's been a rough couple of weeks in the Fleet, managing drills, scheduling deployments, reading through and signing reports. Just the thought of seeing a sheet of paper gives him a headache now. His eyes were tired from staring at his holographic screen for too many hours, dark circles more prominent than he liked. Caleb always struggled with sleep. He was just better at hiding it than his meimei was.

He forced a chuckle, rubbing the bridge of his nose. “If I'm not, I will be one hundred percent a-okay once you're here.” Her sceptical hum was his only answer, the little seed of doubt had landed in her mind, so he scrambled to not let it take root. “I promise I'll give you anything you want. No matter what. I always keep my promises, don't I?”

A smile stretches on her lips, she looks around her, excitement and anticipation bubbling inside her.

“Anything?” She asks, her voice lowering to a more sensual ring. Caleb swallows thickly, recalling their texts from last night. The pictures she sent, the ones he responded with, the dirty words exchanged, both of them needy and charged with sexual tension.

He palms his semi-hard cock, clearing his throat. “Anything, baby. I'm all yours.”

“I'll hold you to that, Colonel.” She hums, smiling to herself, a small blush dusting her cheeks.

He shakes his head, the tips of his ears tinted pink, a smile taking purchase on his lips. “Are you sure you don't want me to pick you up?”

She shakes her head, before remembering he can't see her. “No it's okay. If you did we'd never make it home.”

“What's that supposed to mean? Are you doubting my ability to drive us back safely?” She giggles at how offened he sounds. That little bit of worry lifts off her shoulders. If he can joke like this, whatever is weighing him down isn't as heavy as she feared. “Pipsqueak, did you forget? I'm a pilot. I can manage a car.”

“That's not what I meant!” She snorts, biting her lip again. “...I don't trust myself to not climb in your lap and give everyone a show.”

On the other side of the line, all is quiet for a few moments. Worried, she shifts her weight on her feet, her grip on her suitcase loosening, then tightening again, playing with it.

“... Caleb?”

She hears shuffling. “I'm on my way–”

“No! I told you–”

“Trust me, my car's windows are so tinted it's illegal–”

“My cab is already here!” The lie slips out easily. “Just wait for me! I'll be there in a few minutes! Sit on the couch and relax or something! Don't come! Bye, Gege!” She hangs up quickly, turning her phone off because she knows he'll try to call back.

Her hand covers her mouth, muffling her laugh. He sounded so eager, she could almost see the moment he connected the dots, and how he probably sprang to his feet from where he was sitting. Hopefully he doesn't come looking for her.

She had worked herself up last night, even obeying him when he said no touching yourself and kept on denying her despite her protests. She slept uncomfortably, with her panties changed after ruining the other pair, but still hit and bothered, aching for relief.

When a honk pierced the air, she almost thought Caleb was there, raising her head but being met with her cab driver. She loaded her case in the back and climbed inside, giving the address to the driver and sitting back on her seat, her foot tapping anxiously as the minutes go by.

It almost feels like it takes forever, but when she finally punches in the code to his house, the door opening, she's a little disappointed to not find him waiting for her on the side. She did tell him to relax but Caleb always greets her at the door. Maybe he's cooking something and he didn't hear the door?

Sceptical, she abandons her shoes and luggage at the entrance, walking down the hall.

“Caaaleeeb~.” She calls out sweetly, stopping in her tracks when she reaches the living room. There on the couch, Caleb's chest rises and falls slowly, his eyes closed, long lashes fanning over his cheeks, his faint freckles barely discernible to the untrained eye, but Sienna can make them out perfectly.

She smiles, making her way over to him, sitting next to him on the couch, her hand gently shaking him. “Gege, I'm home.” She whispers softly, pecking his lips, but the boy barely stirrs. She giggles when he makes a soft sound, grabbing a pillow to support his head, cuddling into his side.

“If you were so tired, why didn't you say anything?” She pouted at him, even if he couldn't see it. “Caleb, you big dummy.” Her hand reaches up, brushing his bangs from his forehead. “It's not fair… You talked so big last night and now you're sleeping.” She huffs, leaning her head on his shoulder, her eyes trailing his body, stopping at his waistband. Caleb's shirt is riding up just enough to show a sliver of skin, the prominent veins on his lower stomach and happy trail all peeking through, as if taunting her.

Stupid Caleb, how could he be asleep right now and after everything he promised her? After all the dirty words, the photos he sent, making her promise not to cum unless it was his fingers, his tongue or his cock so he could feel her. And yet here he was, dozing off, completely oblivious to the sexual frustration making her thighs rub together.

I promise I'll give you anything you want. No matter what. I always keep my promises, don't I?

His voice echoes in her mind, mocking her, a small frown scrunching up her brows. Sienna decided then. She was going to ‘help’ Caleb keep his promise.

She peeled herself off his arm, her hands undoing the loosely tied bow of his pajamas, dragging down then down along with his boxers, revealing his flaccid cock. The sight alone made saliva pool in her mouth, her hand taking a hold of him, lips parting, taking his tip in. She glanced at him out of the corner of her eye, seeing no reaction, no microexpressions on his handsome face, only the dark circles under his eyes and the steady rise and fall of his chest.

Making a small sound of frustration, she took more of him in, rubbing whatever inches were left with her hand. Her tongue swirls around him, all her cheeks hollowing as she sucks wherever she can fit, drooling all over him, coating him in her spit, letting it drip down to the base. Her head bobs, letting him hit the back of her throat, tearing up as she gags, hearing quiet sounds coming from him, gradually getting bigger between her lips.

Relaxing her jaw more, her other hand tucks hair behind her ear, attempting to get him past her throat, with little success. She couldn't fit him, not all the way, even with his help and how patient he was (a rare phenomenon when it can to this specific kind of foreplay), it was a challenge. Her hand sneakily slipped under his shirt, pushing it up, exposing his tight abs, his chest, a tingle of pleasure in between her thighs calls her attention.

Sienna watches Caleb's expressions, a subtle twitch of his sharp brows, his nose scrunching a little, but his eyes remain closed, and his chest rises and falls, slow and steady. She smiles a little around his glands, popping him off her mouth, stroking him languidly as she starts kissing his stomach, hearing him mumble and hum but not move a muscle. Her lips find his left nipple, her tongue flicking out to lick and suck on the little nub, feeling his cock throb in her hand, a barely there frown on his face.

“You're really not going to wake up?” She whispers with a pout. She tuts at him, letting go of his stiff cock and rising to her feet. “Fine. Have it your way.” Her hands undo the buttons and zipper of her shorts, dragging them down her soft thighs along with her underwear, reaching for her t-shirt next. “But you can't be mad at me for doing this when you wake up.”

Climbing on his lap, she took him in her hands, angling her hips so she could grind against him, her slick that had gathered between her swollen folds coating his underside. A whimper slips from her wet lips, his taste still lingering in her mouth as she presses down harder on his cock, making sure her clit presses right on his tip before it catches at her entrance. Slowly, she lowers herself down on his shaft, gradually taking more, the slight sting of her walls as they stretch to accommodate him only makes her want more of it. More of Caleb. When she reaches the base of him, her head falls back, her face hot, her heart racing in her chest.

Somewhere in the back of her mind, she knows she shouldn't be doing this. He's vulnerable; unconscious, but she knows he'd want this. Of course he would. He's her Gege, he always goes the extra mile just to see her smile. He'd no doubt want her to take whatever she needed from him, hell, he'd encourage her (enable her) to take charge and use him.

“Letting me do all the work for once, huh?” Sienna grumbles, trying and failing to glare at him, the tip of his cock pushing right up against the soft entrance of her womb, making her shiver and falter a little. She's not usually on top (not from her lack of trying, but thanks to a certain greedy Colonel who can't seem to keep his hips and hands to himself), a little unfamiliar with the added pressure, thanks to her own weight.

She starts slow, her hips moving lazily, back and forth, making sure the curve of his dick rubs against every crevice, every sweet spot, making her thighs tremble, her clit begging for relief. She doesn't wait till it gets unbearable, playing with herself, matching the rhythm to her rocking on his cock. Little sighs and whines leave her freely, caught up in the moment, the sensation of being so utterly filled makes her head spin. Leaning back, she supports herself on his knee, watching him, still sleeping peacefully, his shirt still up for her hungry eyes to ogle him freely.

Caleb's hands twitch at his sides, a muffled sound making its way in his throat and getting trapped behind his closed lips. His brows twitch again and his stirs, head rolling to the other side, before going still again. Sienna doesn't even notice, caught up in her own little world of pleasure, her cunt soaking him with her juices that pool at the base of his cock and stick to her inner thighs in thin, clear and white strands of cum.

Sweat builds up over Sienna’s brow, her hips this time lifting up and sinking down, ripping an unexpected moan from her, her eyes closing tight. She leans forward, using both her hands to support herself on Caleb's shoulders, biting her lip, so close to his face, his breath fans over her mouth. She starts raising her hip to fuck herself harder, faster, with more urgency, more energetic now that she's found a rhythm.

Leaning forward a little more, she leaves small kisses on his cheek and neck, biting back a strangled whimper when her clit grazes against his pubic bone. But that alone is not enough. She's been so wound up and stressed lately, teasing herself and taking it slow is not going to cut it, not even close. Breathing heavily, her hand slips between their bodies, once again finding her slit and rubbing while she bounces on his lap, the wet squelch of her pussy hugging Caleb's cock loud in her ears.

Her ass jiggles when she forces herself to go faster, her walls fluttering when she hears a groan next to her ear. “Gege.” Sienna whispers, her lips grazing the side of his mouth. She pinches her clit like he would, mewling, her thighs burning from the exertion, yet she can't stop. Driven by pure desire and lust, she leans back, the strap of her bra slipping from her shoulder, her delicate fingers twisting one nipple, looking down at Caleb, who's starting to get a little noisy himself.

“Caleb.” She moans, trying to think of what he'd say to her in the moment. Would he praise her for riding him so nicely? Would he scold her for doing whatever she wanted again? Her mouth opens wide, no longer able to keep her volume in check, her own nails digging in the softness of her breast when his hips subconsciously buck up into her once. “Mmmn…!” Hand to her mouth, she switches to moving up and down instead, eyes nearly crossing when her full weight slams down on him, the tip of his cock nudging her sweetest, deepest place.

“Fuck…” Her clit is so slippery, her fingers gliding over creating more lewd noises to deepen the blush on her face. “Ngh! Ah– Leb!” His hips push up again, but when she opens her eyes, it sees his clenched tightly fists, his chest rising and falling faster, eyes moving behind his eyelids, lips parted and dry.

Is he dreaming?

Sienna’s panic dissipates easily, returning to her current position: spelling her name with her hips on his cock.

“Mn, wake up already.” She pants, eyes barely able to stay open, greedily pushing harder to take him impossibly deeper, his leaking cock giving little kisses on her womb, the lower stomach tight with tension. Her walls cling to his girth, her movements getting sloppy, once coordinated and timed thrusts now have no synchronization, her body painting a clear picture of desperation as she helplessly humps him.

“Caleb… I can't take much more.”

Her untrained legs are vibrating with exhaustion from maintaining this position, another swipe over of her hand on her clit, the caresses turning frantic, hurried, the coil that's been wound up in her lower stomach is begging for that one push. Tears of frustration build up in her violet eyes, she keeps looking at where their bodies meet, trying to slam herself harder on him, faster, but her body is failing to obey her.

“Please.” Her voice cracks. “Ge…”

Suddenly, a pair of callused hands grab her waist, lifting her up and bringing her back down with more force than she could muster. The kind her body has grown accustomed to, the one her body craves and unknowingly seeks out, no longer able to be satisfied with fleeting touches, the same roughness and necessity that mirrors her own hunger.

“Sienna.” Her core clamps down tight at the growl of her name, the low tone sending a swarm of butterflies to her stomach. Her head snaps up, meeting stormy purple accompanied by bright rose gold suns. Her arms immediately reach for him, their lips crashing in a mess of teeth and tongues, moans and groans swallowed behind wet lips.

Hands messing up his soft hair, nails gently scraping his scalp, she pulls back with a gasp, rocking her hips hinting at her need, the tangible desire that bubbles dangerously between them.

“Caled, need to cum, please make me cum.” Soft lips peppering kisses on his own, his grip on her hips turning demanding, possessive.

“Naughty girl, mei.” There's no bite in him, his own body responding so willfully, ridden with tension. This is not a dream, Caleb concludes, feeling her nails dig into his shoulders. “I don't remember teaching you this kind of wake up call.” As he talks, he picks up speed, seeing her eyes lose focus, feeling her body give way easily for him to reach deeper. Just how long has she been up to this?

He wants to pull his hair out. His most precious treasure was needing him to fuck her silly and he fell asleep and forced her to take matters into her own hands. He couldn't be mad at her, naturally, he was mad at himself for missing out on the look on her eyes when she took him inside her, missed all the sounds, all the sensations of her adjusting to fit him. He won't miss this. No, he was going to make her cum, and he was going to see everything, with as much a clear mind as he could…

His lower stomach is spasming, the release building slowly, now at the precipice of dragging him under. Caleb's thighs flex and relax, his hips bouncing her on his lap, feeling a sense of pride in his chest when the faintest of smiles lift up Sienna's parted lips.

“Yes–” She cries, her orgasm, forehead tapping his, every snap of his body sending electric shivers of pleasure up her spine. “ ‘m gonna… Caleb, I'm cum–!” A gasp cuts her off but he can already feel her about to fall apart.

“Go ahead.” He encourages through gritted teeth. “Cum. Make a mess on my cock. My sweet, beautiful girl. Claim my cock with your pussy, baby.” Make me all yours.

Her body seizes, her head dipping down and taking a good chunk of his shoulders between the teeth. She bites down, milking him for every drop. His eyes roll up and back, the vibrations of her moans coming from her mouth on his skin tickling his head just right, his own nails digging into the skin of her waist. He spills everything he has to offer inside her welcoming channel, the velvety feel of her massaging his spent member even after she's let her body mold onto his own.

Wrapping both arms around her back, Caleb turns his head, lips finding Sienna's damp with sweat hairline, and pressing kisses all over. Her breathing still irregular, body relaxed and mind blank, her only response is to him, and close her eyes, burrowing close in his neck, tucking her face in as she used to do when she was small.

The action tugs at Caleb's heartstrings, his stomach doing a flip. Tucking hair out of her face, he basks in the after glow, the golden setting sun pouring in from his window only further softening her features. His smile is wide, almost hurting his cheeks as he gazes at her, full adoration, full of wonder.

He kisses the tip of her nose, seeing her eyes blink open, big and wide, staring up at him, a slow smile stretching to copy his own. “What?” Sienna giggles, a little flustered, feeling vulnerable thanks to the tender look in his eyes.

“Welcome home.” He says simply. But that one sentence, the two words burrow deep in her chest and wrap around her heart like sweet, thick honey, soaking in their familiarity. Content, see cuddles closer, tracing patterns over his heart. But Caleb recognizes them almost immediately.
