Work Text:

The House of Lamentation was as lively as ever. 

 

With her sudden disappearance from the human world to Devildom for well over a year, Diavolo thought it would be much better and safer to have common visits to Devildom until he came up with a permanent solution that could have Tsuki living in Devildom for the rest of her life if they desired to. She needs to give it much thought since she would be leaving behind the life she only knew, the life that she grew up in. 

 

But for now, visits would do.

 

It has been three months since they have last been down here and by everyone else's standards, it was simply a crime to be away for too long.

 

“Tsuki! Ya can’t just leave me alone like that! I hate it when you go to the human world! Yer so fragile and everything! What if you choked on something and your favorite guardian demon wasn’t there? Or even worse, a crying woman was looking for her drowned children and found you instead!”

 

“I missed you too, Mammon. I can handle myself, I promise.” Tsuki wrapped her arms around Mammon and gave him a tight hug. He towered over her, as everyone else did in the House of Lamentation. Mammon awkwardly held her back before he pulled away from her and looked up and down the hallway they were in. “What was that about a crying woman?”

 

Mammon gave them a sheepish smile. “There was this movie me and Satan watched the other day and it scared the crap outta me. He convinced me to watch it with him, saying how if I’m so tough and shit I could watch something small like this. Now I’m fucking paranoid!”

 

“Relax Mammon, she only appears near rivers and such. Don’t be such an idiot. Do you see any rivers in the House of Lamentation?” Popped in Satan as he gestured around in the hallway. A trail of floating candles and quills followed behind him, something that did not phase Tsuki as much as before.

 

“Satan, be nice to Mammon.” Tsuki sternly said to Satan. Satan followed her voice underneath him and widened his eyes when he realized it was Tsuki that spoke. A flash of regret showed in his eyes before he quietly spoke to her.

 

“. . . Sorry Tsuki. I didn’t know you were here.”

 

“It doesn’t matter if I’m here or not, you still gotta ease up on him, ok?” Satan nodded his head at her before looking back up to Mammon.

 

“Sorry, Mammon. I’ll try not to tease you so much. Fair enough?”

 

Mammon pointed his finger at Satan. “Fair enough my ass! You literally made me watch that movie! How were you not scared?” Mammon huffed out as he crossed his arms and pointedly looked away from Satan.

 

“I thought it was funny to see how you reacted. I wasn’t really bothered, especially with us being demons.” Satan grinned out.

 

“It wasn’t for me! It was horrifying! What if she comes after me? I mean . . . not like I couldn’t take or anything. She’s just a withered, old ass ghost that is still determined to find them . . . no matter . . . what . . .'' Mammon's eyes widened as his overactive imagination went into overdrive. Tsuki could see the gears spinning in his mind as thought of all of the horrible ways this woman could hunt him down and end his sinful life. Tsuki needed to make him snap out of it before he started begging for mercy.

 

“Mammon, do you want a hug?” Tsuki offered sweetly to him. Mammon looked at her with tear-stricken eyes and nodded. Tsuki walked over to him to wrap her arms around him but was suddenly pulled into his warm chest in a tight embrace. Mammon buried his face into her red hair. They felt him relax against them and squeezed him back.

 

“I got you, Mammon. I’m here, ok? And all in one piece too. I’ll be here to chase all the monsters away.”

 

“I’m still your number one, right? Even when you got Lucifer basically going crazy for ya even if he doesn’t want to admit it. He says he’s fine, that we should go back to doing our tasks and shit but I can see how restless he gets every day that you’re not here. His little brother knows him the best.” 

 

“What about me going crazy and restless, Mammon?”

 

Mammon jumped at Lucifer’s presence, breaking their embrace while Satan simply rolled his eyes. Tsuki turned to see Lucifer and realized how much they have ached for him. 

 

He wore his casual attire, his two-piece suit, except this time he didn’t have his heavy long coat. He still had his ever-present frown, however. 

 

“No-nothing at all Luci! I didn’t see you there, you sneaky little bastard.” Mammon nervously wiped his sweaty hands on the front of his jeans before looking down at his wrist to his imaginary watch. “Oh geez, look at the time, I got a modeling shoot to do. You know how I am. Busy, busy, busy!” Mammon nervously chuckled out before trying to slip past Lucifer before being caught by his forearm. Lucifer leaned down and whispered something in Mammon’s ear that made the nervous smile go away.

 

“Any-anyways Tsuki, good luck with dealing with Lucifer, haha. I need to clean the stupid kitchen. Beel raided the fridge again and I got stuck with cleaning the dishes so you know how it is. You’re gonna hang out with me later to make for this!” Mammon said as he slinked away to the kitchen, dreading to clean the mountains of dishes.

 

Taken aback at the sudden flip of attitudes, Tsuki dumbly nodded. “Of course, wouldn't want to miss it.”

 

“Insufferable, as always,” Satan muttered underneath his breath. “I’ll catch you later, Tsuki.” 

 

“You’re not free from this either, Satan. I’ll have a word with you later. Tsuki. My room. Now .”

 

“Looking forward to it.” Satan sarcastically said as he left the hallway, off to do God knows what.

 

Once everyone had left the hallway, Tsuki crossed her arms and stared at Lucifer. “And it’s nice to see you too, Lucifer.”

 

Lucifer brushed past them, heading towards his room. “Let’s go, we have many things to catch up on.”

 

All Tsuki could do was follow, going through the door when he opened it for her. She could have sworn that she saw Lucifer look down both sides of the hallways before closing the door and locking it, not wanting any interruptions from anyone.

 

“Ok, Lucifer, can you please tell why you were acting like that mmph !” Lucifer pinned Tsuki against the door, fiercely kissing her as his hands grabbed at her waist. Tsuki was stunned at his reaction before quickly melting into the kiss, her arms loosely wrapping around his neck as high as she could as they tried to keep up with his desperate kisses.

 

“Why didn’t you come straight to me?” He said in between kisses. “I missed you so much.” A tug at her lips. “Three months are unbearable without you.” His hands gripped her ass through her dress, making her gasp into his mouth. 

 

“Luci—wait, Lucifer.” Tsuki gasped out, weakly pushing Lucifer away to give her some breathing room.

 

“You’re mine . You belong to me . I don’t want anyone else having you today. Today, you’re staying with me, locked in my room until I say otherwise.” A harsh bite at the side of her neck, blood slipping down her dark skin. Lucifer licked the side of her neck, tasting her. If it wasn’t for him pinning her against the door they would have collapsed from how quickly sensitive they had become. 

 

“Lucifer stop, please .” Tsuki commanded him. Lucifer stilled at his actions and slowly moved away until there was space between them. Tsuki breathed in some much-needed air, not making eye contact with him. Lucifer let her take her time to steady herself before he let himself speak.

 

“I’m sorry love, I didn’t mean to jump onto you like that. It’s just that,” Lucifer heavily sighed as he looked away from her, “I really missed you, and seeing you with my brothers made me feel like . . . like I just wanted all of them gone and just wanted you to myself.” Lucifer’s words hung in the air as the silence stretched on between them. Tsuki looked towards him, towards shy and embarrassed Lucifer. He felt guilty for his actions, she can tell. They cupped his cheek and made him look down at her so that she could properly look at him. Lucifer leaned to her touch, nuzzling against the palm of their hand.

 

A warm smile appeared on Tsuki’s face, her brown eyes looking into Lucifer’s red ones. “It’s okay Lucifer. I don’t blame you at all. I would have liked some sort of warning, that’s all. I forgive you.” Lucifer leaned down to kiss her brow before resting his forehead against hers.

 

“I love you, Tsuki. Irrevocably so. You’re the only one who I would give this blackened, sinful heart that I have.” Tsuki opened up her arms and Lucifer dove himself right into them, burying his face onto the top of her head, red hair tickling against his cheek, and breathing her in. He was soaking up their warmth, apologizing for lost time. 

 

It always surprises him but he can never get over how small they are compared to him.

 

Lucifer shifted into his demon form and wrapped his wings around her. He wanted all of him to hold her, to shield her away from the world, to have her for just himself. The tips of Lucifer’s wings tickled against Tsuki: the small of her back, behind her neck, the sides of her arms and legs. Every touch was appreciated and loved. She loves how Lucifer puts all of his trust and heart in her fragile, human hands and she puts all of her in his bloodied, scarred hands.

 

They wholeheartedly belonged to each other.

 

“Luci?” Tsuki quietly asked.

 

“Yes?” Whispered out Lucifer against the top of her head.

 

“I want you. Please. I’ve missed you so much . . .” A sharp intake of breath was heard above her and Lucifer’s grip on her waist tightened. Tsuki softly gasped at his grip and slightly squirmed. 

 

“Tsuki . . . You cannot just ask me things like that out of nowhere. You’re going to drive me insane. Can’t I just hold you and appreciate you?” Lucifer breathed out, finally looking down into her eyes.

 

“Well,” Tsuki said with a sly smile on their face, pushing her lower half against Lucifer’s front. Lucifer hissed at the friction and a sudden shift in his eyes told Tsuki they were getting into dangerous waters. “You could appreciate me in other ways, Luci.” Wrapping her arms around his neck, Tsuki pushed Lucifer down to kiss him, slowly and sensually. Lucifer was quick to kiss her back, his tongue sliding against the bottom of her lip. 

 

“Vixen.” Lucifer whispered out between kisses. Tsuki opened her mouth and let Lucifer deepen the kiss, his long tongue swiping over the roof of their mouth. Tsuki squealed at the feeling, gripping his shoulders as he guided her towards his closet, his lips never leaving hers.

 

“Strip. You know what to do.” Lucifer said before he pulled away from her, opening his closet to look over at the various bondage equipment he had collected over the centuries. He heard the rustling of clothes behind him and smiled to himself.

 

Such a good girl.

 

Lucifer looked for the thigh cuff bondage that he couldn’t stop fantasizing Tsuki in. It made him shift in his seat whenever thoughts of her would flow by. The leather squeezing around her thighs as he drove himself ruthlessly into her warm heat, Tsuki crying out from him to go harder sir. It made him palm himself, clothes and all until he was panting against his desk. 

 

He found what he was looking for: four straps of brown leather with gold rings and chains. He turned around to see that Tsuki was already on her knees, bare with her hands neatly tucked behind her back and her head lowered, waiting for her master’s orders. Her clothes were also neatly folded.

 

The perfect picture of submission. 

 

Well . . . almost.

 

She kept her black, lacy panties on.

 

“Didn’t I tell you to strip?” Lucifer said as he raised an eyebrow at her. Tsuki looked up to him with a gleam in her eyes.

 

“Yes, but I thought it would be better if you took them off yourself. I’m such a poor human who can’t do anything for herself.” Tsuki grinned out to him, widening her legs ever so slightly.

 

“If you want to be a tease then so be it. Get up.” Tsuki did what she was told and got herself up, looking up towards Lucifer’s intimidating glare. 

 

“Sit at the edge of the bed.” 

 

Tsuki slid her gaze away from Lucifer without saying much of a word and headed towards the bed. She sat down on cool, dark, satin sheets and spread her legs, a small rebellion of how the thing Lucifer desires the most is hidden behind a flimsy piece of cloth.

 

“Aren’t you going to take these off of me, Luci?” Tsuki innocently asked him. “Or are you going to put that on me first?”

 

“I’m glad you asked, dear . I’m going to put these on you first since you’re acting like a damn brat .” Lucifer said as he quickly took off his gloves, his black claws coming out in full display as he pocketed them in his back pocket. He stood over Tsuki and grabbed her leg, fastening the leather around her thigh, not breaking eye contact with them at all.

 

“You want to tease me? Play this little game with me?” He switched to the other leg and harshly tighten the leather around her. “Fine. I hope you know what you have gotten yourself into. Wrists.” 

 

Tsuki felt fuzzy from the way Lucifer was treating them that she almost didn’t hear what he said. She put her wrists at her sides and let Lucifer cuff her.

 

“Too tight?” 

 

Tsuki gave an experimental tug. They couldn’t move her writs more than six inches away from her thigh but other than that, they were comfortable. “They’re fine. Thanks, Luci.”

 

Lucifer gave Tsuki a light kiss on her forehead, mirroring the same place that his black diamond would be, before he grabbed them by the waist and switched their positions, Lucifer sitting at the edge of the bed and Tsuki on his lap, both of her legs on his right side.

 

“Why won’t you be a good girl and take off my pants for me? I’m quite busy at the moment.” Before Tsuki could ask how he’s busy she felt a bite on the same place on their neck that he bit earlier, his teeth sharper than before. She moaned at the feeling before remembering that she was supposed to take Lucifer out of his pants. 

 

Being bound that she is, it was hard to maneuver her hands and even harder to focus when Lucifer was sucking her most sensitive spots on purpose. But if she shifted here and moved their closest hand over there she could slip off the button, tug on one side of his pants so the zipper would slide down, and then she can grab the elastic band of his underwear and pull them down to the top of his thighs but no further.

 

“Luci, you’re gonna have to move. I can’t pull them down.” Without missing a beat, Lucifer grabbed them by their waist with one arm and lifted them until there was enough space to slip his other hand between them to grab and pull down both his pants and underwear to his knees.

 

“Spread your legs.”

 

“Huh?”

 

Lucifer grabbed one of their legs with his now free hand and spread them apart. He lowered her onto his lap, sliding his cock between their thighs. Tsuki was not a stranger to seeing Lucifer’s demonic features but it always made them hornier whenever they saw his monster dick, knowing that sooner or later it was going to be inside of them. It was a deep red and it was bigger than what Tsuki felt when they were feeling him up. The base of his cock, his pubic bone, was black, just like his claws. “See? Was that so hard?” The feeling of his dick pressing up against their clothed sex made them rock her hips against him. She fluttered her eyes at the feeling and did it again, making them both groan.

 

“Stop being a tease.” Lucifer gritted out.

 

“And where’s the fun in that?” Tsuki grinned out.

 

“That’s it, you had your fun.” Before Tsuki could say anything she felt herself being pushed onto the bed, her bare back falling onto the mattress before being dragged to the edge of the bed to where Lucifer was standing. He grabbed her legs and threw them on his shoulders, one hand sliding down to her hip to dig his claws onto to. He slides his cock over her clothed clit and groaned, the fabric teasing him. Tsuki didn’t realize how much she wanted to be touched and unknowingly spread her legs open for more. 

 

“Lucifer . . . please don’t stop.” Tsuki whimpered out.

 

“This is what happens to brats that tease.” Lucifer began to slowly thrust between her thighs, a dribble of precum smearing against her panties, mixing with the dampness on front. Every movement, every slide had Tsuki biting her lip and fisting the sheets. He barely even started yet she still wanted more.

 

“Faster, please. I need more.” 

 

“Even though this is your punishment you ask to be rewarded? Clearly, you’ve been away for too long.”

 

“And clearly, you were desperate to get your hands on me— ack! ” Tsuki’s words were cut off as Lucifer completely wrapped his hand around their throat, his claws pinching her skin.

 

“You need to check your tone with me, Tsuki. Now, be a good girl and take all of me, and maybe I’ll go faster. Deal?” 

 

All Tsuki could do was nod, the pressure around her throat and the steady decrease of oxygen making her twitch and leak against her underwear. Lucifer noticed and quietly chuckled to himself, shifting her legs on his shoulders into a better position before dragging his cock against her sex.

 

“You really thought you could tease me? Make me bend to your will and give you what you want? Ever since you left, I’ve been getting off like a bitch in heat. It was never enough for me. You made me like this.” His grip around her throat tightened, the friction on her clit quickened, and the claws on her hip dug deeper. Tsuki weakly grabbed at the sheets, the oxygen in her brain limiting as she felt a twinge of fear at the edges of her mind. She felt the knot of pleasure twisting into a tight ball, her eyes fluttering shut as she lifted herself higher onto Lucifer’s shoulders. Lucifer noticed Tsuki’s unfocused eyes, the way she was subconsciously grinding onto him and pulled away from her, dropping her legs and letting go of her throat in the process.

 

“Are you done misbehaving?”

 

“Are you gonna fuck me now?” Tsuki breathed out. 

 

“Pity.” Lucifer chuckled out as he moved her panties off to the side. “And here I thought you learned your lesson. Look at you, you’re so desperate.” He said as lowered himself onto his knees, down toward her cunt. He ran his claws down her sex, collecting her arousal. His horns brushed against their thighs, the cool and ridged texture tickling her. Tsuki bit her lip as she felt his fingers tease her. “You’re making such a filthy mess of yourself.” 

 

“Didn’t you just say you were getting off like a bitch in heat? It sounds like you’re the desperate one Luci— ohh !” She felt Lucifer’s lips wrap around their clit, sucking and rolling his tongue around her. Tsuki desperately wanted to grab his horns so that she could push him closer but with their hands cuffed to her thighs, she couldn’t have even brushed their fingers against him.

 

The way he flattened his unnaturally long tongue against them before swiping against the sensitive bundles of nerves with the tip of it made them want to close their legs from how much the feeling was.

 

Lucifer gripped her inner right thigh with his claws, piercing her dark skin, and spread them apart.

 

“If I were you I would keep still. I wouldn’t want to hurt you more than I have to.” Lucifer breathed out against her, his warm breath tickling against her sensitive skin. He kissed on their inner thighs, teasing her with his soft, warm lips that were so close yet so far away from her desires. Tsuki tried to keep still but she couldn’t help but squirm whenever he licked a stripe up her cunt, lapping at her like he couldn’t get enough of them no matter how much he drank them in. His wings were showing signs that he loved doing this with how much they were softly flapping. 

 

If there is one thing that Lucifer liked doing during sex other than teasing was eating someone out. Just the thought of them shaking by just his tongue made his cock twitch. He slipped his tongue inside of them and felt them clench around him. Everything was becoming too much for them and if he kept going like this she might cum.

 

He made direct eye contact with her and smiled as he continued to lick them, both inside and out.

 

“Lucifer,” Tsuki breathed out, pressing themselves closer against his mouth, “think I’m gonna come.”

 

Lucifer hummed around them, the vibration going through her clit and up her spine but other than that, he didn’t respond to them. She wanted to grab something solid other than flimsy sheets but with their wrists bound she was completely helpless. 

 

“Sir? Can I come, please?”

 

This time Lucifer acknowledged her and pulled away but not before he used his tongue to lick up the juices that Tsuki left on his face, effectively cleaning all of himself.

 

If Tsuki wasn’t trying so badly to be his good little girl and wait for his command they would have cummed right then and there. 

 

Lucifer thought to himself as Tsuki took deep breathes in what seemed like forever. She also wanted to ask if he could take off the thigh cuffs so that she could properly hold and scratch him just like they both like it but she didn’t want to push her luck. He looked at them with a smirk tugging at his lips.

 

“You only behave for me when you want something from me. You even called me sir. It’s amusing to think your actions could sway me.” He was massaging their thighs, a sign they knew very well that they weren’t going to get what they want. Tsuki thinks that Lucifer doesn’t even know he subconsciously does it.

 

“So . . . is that a no?”

 

“Why would you even doubt it? Of course it’s going to be a no.”

 

Lucifer dove back between her legs, his horns now scraping against her skin. If Tsuki thought he was being rough with them before this would be considered murder. He devoured them, sucking their soul out of their sinful body as he bobbed his head between their legs. He used the same technique of flatting his tongue against them before flicking the very tip of it onto their clit. Tsuki moaned and strained against the leather, their wrists now irritated from the constant friction.  

 

He spreads their legs even wider, wanting to take everything he can. Their moans, their pleas, the arousal that’s spilling from between their legs, the way that they’re sighing out his name, his name, over and over again. 

 

He absolutely loves breaking them into his obedient doll.

 

“Lu—Luci, please . . .” Tsuki whined out.

 

Lucifer pulled away from her, now kissing her vulva, away from her throbbing sex. His fangs bite down on the meat of their inner thighs, beads of blood slowly rising until it fell onto the sheets. He wanted to leave teeth marks only they would see, only they would feel when they rubbed their thighs together. He wanted to edge her until she was incomprehensible, saying things that they wouldn’t have thought of saying.

 

“What is it that you want from me?” Lucifer whispered out against their skin as he toyed them with his teeth, kissing and sucking wherever he pleased.

 

“Fuck me. Please, please, please. I can’t take it.” Whispered Tsuki.

 

Lucifer finally pulled away from them and shifted his weight on his knees ever so slightly before climbing onto the bed. He was hanging over them as he placed his forearm on the side of their head, his wings blacking out the dim light of the room. 

 

“Do you know how much your taste is driving me mad?” He grabbed Tsuki’s chin and leaned down to deeply kiss them. Tsuki parted her lips in response, letting Lucifer make her taste herself. She felt Lucifer’s hand that was on her chin travel down their body, a trail of goosebumps following his claws. Tsuki moaned in Lucifer’s mouth as he easily slid two fingers inside of them. His fingers were thick and the way his claws gently scraped their insides were not unpleasant by the way they squeezed around them. 

 

“You could have gotten what you wanted if you had simply obeyed my commands. Is it that hard to follow a simple order?” Lucifer breathed out against them with a smile on his lips. Tsuki moved her head away from his mouth to say something back but was interrupted when Lucifer slipped a third one in, curling them against her g-spot. Tsuki let out a cry while Lucifer simply grinned, his fangs on full display as he stretches and thrusts his fingers faster and faster.

 

“Just look at how you swallow around me. You’re desperate for this.”

 

Tsuki rolled her eyes as she felt their orgasm creeping up again. She wanted to cum so badly they didn’t care if they disappointed Lucifer. His fingers felt so fucking godly, as expected from what God created for His favorite. Their toes were curling, their hands were gripping the bedsheets, and they were arching their back.

 

“Lucifer! I’m gonna— no! ” Tsuki screamed out when Lucifer pulled out his fingers. He sucked them clean with a smile, taunting her. Her legs were shaking, she didn’t know how much they can be edged for. 

 

“I thought you wanted me to fuck you. Did you already change your mind?” He said teasingly. If Tsuki’s hands weren’t held back by chains she would have smacked him across the face.

 

“Lucifer, I swear to fucking God—”

 

“I wouldn’t bring His name in the conversation when you’re begging me to fuck you.” Lucifer smirked out above her.

 

“I swear, once I get my hands on you I will— God !” Lucifer finally lined himself into Tsuki’s hole and pushed all the way in, inch by throbbing inch until the base of his pubic bone was right against their’s.

 

His cock was hot and heavy, dragging and hitting against their sweet spots over and over again, making them drool. The lewd sounds of sex came in between their heated breathes, loud moans, and grunts.

 

“Please cut the chains,” Tsuki whined out. “I wanna hold you, please.” Not even a moment later and Tsuki felt their hold loosen. She quickly wrapped their arms around his back, dragging their nails to the base of the first pair of wings. She gripped them, making Lucifer moan loudly next to their ear.

 

“Don’t stop, please. I want more. I want everything, please Lucifer.”

 

“Do you have any idea of what you’re doing to me? Of what you’ve done to me? Take responsibility.” Lucifer gritted out as he slammed more forcefully into them. “Keep grabbing my wings like that.” 

 

Tsuki grabbed more harshly on his wings, moving her hands into his feathers and tugging them. She started kissing wherever she could reach: on his collarbones, his throat, the sides of his neck. Every single kiss had Lucifer humming and sighing. 

 

“Please kiss me Lucifer. I want you closer to me, please.” Right when those words left Tsuki’s mouth Lucifer smashed his lips on theirs, tongue going straight down their throat. They kissed back as much as they could, running their tongue over his sharp fangs. Lucifer’s tongue played against hers, lightly sucking and tugging them. 

 

“Feel like— hah —Feel like cumming. Don’t stop— aah —need more.” Tsuki mewled out. She wrapped her legs around his waist, trying to lock him into place but suddenly felt Lucifer pull away, now fucking between her thighs, both of their arousal sliding between them, his dick rubbing against her clit ever so lightly.

 

“Why!?” Tsuki cried out, her hands going straight to her hair to pull at it. She is now fully sobbing, wanting this torture to finally end. 

 

“I want to see how far I can break you. I want to see you cry and beg for it.”

 

“Please just fuck me, Jesus—fuck! Stop!” Lucifer grabbed the bottom of their right thigh and pushed it as far as he could to their chest, putting her on display, now rubbing against their lips. 

 

“Not enough. You know you can do better.” He harshly spat out.

 

Tears were running down their cheeks onto their knotted red hair on the bed as garbled noises came out when she tried to speak.

 

“Fuck me, goddamnit. I don’t care if you have to breed me just please, sir, please, Lucifer, please just fuck me until I cum.” Tsuki brokenly, barely sobbed out.

 

A switch flipped inside of Lucifer as he heard the word ‘breed’ mixed with the sound of her sobs. He quickly moved into a mating press, shifting her legs onto his shoulders as he leaned down onto his knees and shoved himself into her. Skin slapped onto skin as his balls hit against her cunt.

 

“Such a good girl, begging for me like that. You know what those words do to me. I’m going to give you everything you want.” Tsuki barely heard a word of what he said as she was now quickly approaching her orgasm with loud babbles.

 

It came so suddenly and so powerful that she gripped on Lucifer’s neck, breaking her nails as she let out a silent scream, her eyes rolling to the back of her head. She was squeezing around him so tightly he felt that his head was going cloudly. 

 

Sweat clung to his bangs as he pounded inside of her, ignoring her orgasm. He bowed his head against their forehead as he panted and grunted above her. Loud moans were slipping out of his mouth as he tried to hold them back. 

 

Lucifer didn’t want to admit it but there were times where he wanted to snap out of the teasing and edging and just give in to the temptation to just fuck Tsuki to his own needs. She looks so beautiful with her red hair splayed out on his bed as they made expressions that he only imagined. 

 

But he knew that it would be all worth it in the end when Tsuki would be sobbing, pleading for him to just do it already and that is the moment when he can fully go all out without his pride getting in the way.

 

“I’m going to breed you like the filthy slut you are. Fill you up with my seed. You would like that, wouldn’t you?”

 

Tsuki moaned in response, her legs shaking as Lucifer continued his brutal pace. He stretched around her so well she felt full.

 

Suddenly she felt herself being choked by Lucifer’s hand, quite literally stealing her breath away.

 

“When I ask you a question you answer it. I do not like repeating myself.” He gritted out, stilling his movements. She tried to take his hands off of her but she was too weak, their arms feeling like jello after their orgasm. His grip around her throat tightened before he leaned down against their ear.

 

“Do you or do you not like being fucked pregnant?” He spat out. 

 

Tsuki dumbly nodded her head, already feeling the building oversensitivity.

 

Lucifer scoffed at them before taking away his hand from their throat, leaving dark prints on their skin. “What I thought. You are such a damn whore. I know more succubi with more dignity than you. You’re taking my cock so well, so well , darling.”  

 

His black, scarred claws laced with her smooth, brown fingers. His knuckles turned pale and if this wasn’t Tsuki’s first time with him she would have cried out in pain. But she didn’t mind the harsh squeeze because his hand was the only thing bringing her into the moment. They hazily looked down between their legs and saw Lucifer’s deep red cock covered in her cum, sliding down towards her ass. 

 

Lucifer’s wings stiffened as he felt his orgasm coming in. He knew he couldn’t last long. He went harder and deeper inside of them, wanting to come at the same time as them, her breasts bouncing with every deep thrust.

 

“Gonna fill you up with our kids. Make everyone know who you truly belong to. Make you focus on just me.” He quickly moved his claw to their throbbing clit and harshly rubbed at them. “You would never think of another person, another demon , who can fuck you this well.” A hoarse scream left Tsuki’s throat as another orgasm hit her, their toes curling, their back arching, and fists curled so tightly that warm liquid ran down their palms, not that they noticed at all. A deep, guttural moan left Lucifer’s throat from the way Tsuki was just squeezing him dry. Lucifer bites down on the first thing he landed on, his fangs digging deep into Tsuki’s shoulder, and rolled his eyes as he let his cum fill her deep in their womb. 

 

Lucifer slumped on Tsuki’s chest, letting the high wash over them in waves. Lucifer was the first one to move, gently removing his fangs from Tsuki’s skin, the blood falling towards their knotted red hair.

 

“Are you okay, darling?” Lucifer quietly whispered out. “I bite you too many times. I didn’t mean that to happen.” Tsuki made a hum that sounded like they were fine. “I’ll clean and bandage you right now. Can you move?” Tsuki hummed a no as they left Lucifer slowly pull away, shifting back to his human form. Tsuki felt their mixed cum slowly ooze out of their hole and Lucifer held back the need to clean them up with his mouth. 

 

“We need to give you a bath and to make sure we disinfect the bites. I’ll be right back.” Tsuki softly nodded her head, feeling sleep tug the edge of her consciousness. He quickly went to his private bathroom and turned on the bath, making sure the water was suitable for Tsuki. He was about to leave when red caught his eye. He turned toward the mirror and noticed dried blood followed by red streaks on his pale, scarred back. He softly smiled to himself. 

 

They are always full of surprises.

 

He let the water running as he went back into his room and easily picked up Tsuki to the bathtub to where he gently laid them down. He turned off the water and joined them right behind with a soft towel in hand. He first worked with all the bite marks, being gentle as he can with how guilty he felt. He worked on their hair, untangling and tugging on stubborn knots that had dried blood on them. When he was finally done he massaged their scalp with shampoo, ridding the sweat from them. Tsuki quietly groaned at the feeling, leaning back onto Lucifer’s warm chest.

 

“I’m so proud of you. Bratty yes, but you did so well. That fire inside you have amazes me. I never thought a human would make me fall so terribly in love with them.” Lucifer kissed the top of their head as he wiped their neck, down their chest and between their armpits, to between their legs with the towel. He cupped a handful of water and rinsed them, making sure that every part of them was clean. 

 

“I’m going to get you a towel now. I’ll be right back, love.” Lucifer stood as he got out of the bathtub but felt something grab his hand. He looked down at Tsuki and felt them tug him closer. Lucifer complied and softly kissed their lips, his hand cupping their face. The kiss was full of admiration and trust, something that they felt the universe graciously let them experience in their lifetime. They both separated as Lucifer looked into Tsuki’s tired brown eyes. They were so full of life and beauty.

 

“I love you so much, Tsuki. You bring me so much light in my world.” Lucifer whispered in the space between them. He gently picked them up from the water and carried them to the top of the bathroom counter. He wrapped a warm, black towel around them, drying as much as he could with their body and hair. He found the med-kit he recently bought for the sake of Tsuki and got to work on their bandages, gently massaging in ointment around their thighs and wrist and then wrapping them around with gaze.

 

Proud of his work, Lucifer quickly wrapped a towel around himself as he filled a glass of water.

 

“Here, drink this. It’ll make your throat feel a little better.” He slowly let Tsuki drink the cup with his help and let out a hum when they were satisfied. “I’m just going to change the sheets. Don’t you dare fall asleep on the counter.” Tsuki nodded her head and shut her eyes. Lucifer quickly went to his bedroom to strip the stained sheets to change them into clean ones, throwing back all the pillows that has fallen off the bed. When he came back to the bathroom he noticed Tsuki was fighting from falling asleep.

 

“Let’s go to bed, love.” Lucifer said as he carried Tsuki back to his now clean bed, leaving both of their towels behind. He tucked Tsuki in first, making sure her pillows were exactly where she liked having them. He snuggled in front of them, wrapping his arms around the small of their back. Tsuki slowly blinked her eyes, trying so hard to stay up with him.

 

He kissed their forehead before placing her head on the nape of his neck. 

 

“Do you forgive me for hurting you?” 

 

Tsuki barely nodded her head, her hand clutching around his arm.

 

“That’s all I needed to hear. I missed you. So much. More than anyone else. Even Mammon noticed, saying something on how I was ‘mopping around like some fool who was not given his favorite treat.’ The things he says are ridiculous.” This sentence woke Tsuki up as she stared into Lucifer’s eyes with an are-you-kidding-me-face.

 

“Well . . . I supposed both of you are right. You always had a soft spot for him.” Lucifer sighed out, tugging Tsuki’s bare form closer to his. “Now go to bed. I’ll make sure no one else disturbs you. Sleep well, my beloved.” And with that, Tsuki finally let her mind drift, letting the sound of Lucifer’s heartbeat lull her to sleep.

 

Oh, how much they loved this stubborn demon with all of their heart.
