Despicable

Author's Notes: written for slowlange for 2023 wordcrimes! my first work for this fandom and i'm glad its my fave ship!

Loid Forger was a despicable man.

Yuri Briar knew little more than that but what else did he need? Admittedly, he dipped into his records and found nothing incriminating. It was frustrating. How could such a supposedly perfect man exist? Yuri didn’t know. He did know, however, that his big sister, Yor, deserved better.

Yuri knew they couldn’t be together. He dreamt about it but he knew they couldn’t. It just wasn’t possible without the two of them running away together. He couldn’t ask that of her, even if he found out that she had felt the same way about him. He couldn’t be so selfish. He wanted to be. He oh-so-wanted to be that selfish man who drank from his sister’s overflowing cup. He wanted to drink and drink and drink until there was none of her left. None of her left for the cruel world that didn’t deserve an angel like Yor. They didn’t deserve her sweetness. Her smile. Her presence. Her anything and everything.

He wanted to keep her safe. His job didn’t allow him to be with her as much as he wanted to. It was why he reluctantly pushed her to find someone.

It was too bad that she did. It was even worse that she didn’t tell him about it until the very last minute. The worst possible thing was that he had to hear about it from his friend. No, it was the fact that he saw that they couldn’t run away anymore.

Still, Yuri could dream. He dreamed all the time.

This lovely apartment could be theirs. This tranquil life where the hardest thing they had to deal with was their child’s poor grades could be theirs.

He bent over Anya, Loid Forger’s brat, as she scribbled in the margins of her notebook. A scowl spread itself across his face. “That doesn’t look like studying.” Anya sputtered and flailed about as she rushed to cover the incomprehensible doodles and scrambled to scratch down a few answers. He sighed. “It’s important to your mother that you do well in school. How are you supposed to be able to support her later on in life if you can’t even make it through kindergarten?”

The girl sniffled.

Guilt panged in his heart at her expression. It was important to be firm with children but Yor had shown him such kindness and encouragement when trying—and failing to—help him with his studies as a youth. It wasn’t like it was this child’s fault that her father stole his sister from her. Hesitantly, he placed a hand on Anya’s shoulder and gave it a rub. “What I mean is... If you do well in school and focus... you will be able to provide a better future for yourself and your family. Keep trying.”

“Okay, Unkie.”

“Try to finish the next three problems and you can take a break. I’ll check up on you in fifteen minutes. Call me if you need anything.”

“Okay, Unkie,” she repeated.

Without a word, Yuri slipped out of his niece’s room and into the living room. His sister turned towards him and smiled. “Thank you so much, Yuri. I know how hard it is for you to find some free time...”

He lifted his hands. “I’d do anything for you, Big Sister. This is nothing.”

Her smile, her radiant smile, softened as she patted the seat next to her. His heart raced as he rushed to sit next to her. An arm reached around his shoulders and pulled him into a tight embrace. Blood rushed to Yuri’s face and boiled in his ears as euphoria rose inside his chest. Her softness sank into his body. Warmth enveloped him. His eyes fluttered shut as he slumped against her. The scent of her floral perfume permeated his senses. The sensation of her bare skin, the area surrounding her collarbone, burned into his cheek as he drank in her softness.

Yor, Yor, Yor, Yor Yor. What did he do to deserve such treatment?

“I love you, Yuri. You’ve done so much for me and Mr. Loid. How can I ever repay you?”

He swallowed.

She could leave this wretched man. She could abandon this life. She could run away with him to a small town in the north. She could be his wife. She could be safe. She could be happy. She could be the mother to his children. She could be with him. She could be his.

Yuri simply smiled. “I love you too, Big Sister.”

She giggled and hugged him tighter. His bones creaked but he didn’t care as long as he got to stay like this. Unfortunately, all good things had to come to an end as the brat came out with her notebook.

“I’m done, Unkie.”

Before he could even go to check it, Anya rushed to the TV and turned it on. The noisy intro to her cartoon filled the room as the Forger’s dog padded across the room and dropped next to the little girl. Anger broiled inside of him, only for it to be extinguished as soon as he heard his darling, dearest sister’s laughter bubble up inside her ample chest.

The day passed by uneventfully. That bastard Loid Forger did not return home. Yuri didn’t know whether to be grateful or disgusted by this. What kind of man didn’t at least call to say he was going to be late? What could possibly be more important than Yor?!

Frustration bubbled and broiled inside of his chest as the hours passed. He managed to convince Anya to study a bit more after dinner, which was takeout from a nearby bistro. He wasn’t sure if he was thankful for that or not. There were so many memories associated with Yor’s cooking. He loved every bite even if he couldn’t keep it down for longer than a minute. The enthusiasm he had for anything his sister did carried him throughout his childhood. Still, it was nice to be able to actually have a full belly. Anya seemed to think so too. The spoiled child actually reacted poorly to the idea of Yor’s cooking! The nerve of Forger’s kid. What did he teach his daughter?

Of course, the studying didn’t go very well. Yuri wondered if she was a lost cause.

Again.

Once the child was tucked in and asleep, the two of them were alone. This was the end goal. The only thing that could ruin this moment is if that bastard suddenly came home. Was it selfish to spend the whole day with his sister and still want more? Yuri wasn’t sure. He also didn’t care.

He needed more of Yor. The longer they spent away from each other, the greater his need grew. He wanted to hold her. To hold her so tightly that her bones would crush into his. That their souls would merge. To be together forever as one being. Of course, this wasn’t possible. It just wasn’t tangible.

All he could do was fantasize about their possible life together in the north. It was something that used to be tangible. It was taken away from him though. These small, bite-sized moments alone together were all he had left. He was going to make everything count.

Yor smiled at him as she placed a tray of tea and her despicable husband’s cookies from the night before onto the coffee table. Her beautiful eyes drifted towards the clock on the wall before she sat down next to him. “I guess you’ll be leaving after some tea?” she asked.

“No,” he replied. “I... I can’t leave you alone at night.”

The lovely sound of her laughter, warm and tickling like the summer’s sunlight in the morning, filled the room and made Yuri’s heart flutter. “Oh, Yuri, I can take care of myself. I used to live on my own after all.”

He huffed. “I was worried about you then, Big Sister.”

Her smile softened as she pulled him into another embrace. “You’re always looking out for me. Don’t you ever take time for yourself?”

“...It’s the least I could do.” Words spun inside his mind and his throat as he tried to think of something to say that wasn’t horrifically obvious or would make her hate him. Yor was the kindest person Yuri knew but he couldn’t risk her knowing how deep his affection for her ran. He had fantasies of them together, of course, but most sisters wouldn’t be willing to make those a reality. He liked to imagine that Yor would. He couldn’t risk seeing a possible rejection though. He’d stay by her side and protect her by any means necessary even if she told him to stay away from her. It was the least he could do for the most precious person in the universe. “...After everything you did for me growing up. I want you to have a good life and be safe. At least let me stay until your husband is home.”

Her arms tightened around him. Then, something soft and amazing and dreamlike and wonderful brushed against his forehead. Her lips. She kissed him. It was just on the forehead, right where his scalp met his face, but she kissed him. Kisses were peppered along his hairline then along his cheeks and nose. Their eyes locked onto each other’s before she pecked him on the lips and grinned. “Alright.”

Obviously, she didn’t mean anything from it besides sisterly affection.

However, it was enough to get Yuri’s blood pumping. His heart pounded. Heat pulsed through his body and pooled in his groin. His cock throbbed as his palms grew sweaty. He swallowed, his throat suddenly dry and his mouth sticky. He was disgusting. He was perverting her purity with thoughts like this.

“Well,” she started as she pulled away from him. She reached for her cup of tea and brought it to her soft, kissable lips. Yuri watched as her lips parted for the tea and how gracefully her throat moved as she swallowed. His nails dug into his palms at the thought of Yor’s lips wrapping around his cock and how elegant she must look while swallowing his load. He would brush her slightly mussed hair out of her eyes and lean in for a kiss, uncaring that he had just ruined her mouth with his seed. It’d be a real kiss. One that he longed to give her and unlike the chaste innocent ones she gave him. “We should drink up before it gets too cold.”

He shook the perverse thoughts from his head and nodded. The cup clattered noisily on its saucer—damn his still lingering arousal—as he brought it to his lips. Warmth, a softer gentler warmth, spread across his chest as he drank the black tea. The two of them talked about nothing and yet it was everything to him. She asked about his job and his latest business trip. He gave her the standard rehearsed lies that his superiors fed to him. She mentioned her three coworkers. The ones that liked to pick on her—he didn’t understand what Dominic saw in Camilla, personally—but she didn’t realize it. Camilla was going to give her another cooking lesson this weekend so she’d be able to cook something other than stew. He smiled at that thought. The childhood stew she prepared for him back then was delicious. Then, it turned into stories about Anya, their family outings, and other nonsense that made his heart ache.

Over time, Yor’s eyes grew heavier and contagious yawns escaped her. The pot of tea was emptied after what seemed to be a dozen cups on her end. He kept her awake with more lies about his job, trips, and coworkers mistakes. Soon, she leaned against him and closed her eyes. “I’m just resting my eyes,” she murmured before drifting off.

Yuri swallowed.

It was just him now.

His cock throbbed as if it was reminding him of the still lingering arousal from that kiss. That damned kiss. His eyes drifted towards the door and then the telephone that continued to be silent.

Where the hell was that Loid Forger? Disgusting. Absolutely disgusting. Despicable. Such a useless and thoughtless man should just do him a favour and die.

He looked at his sister, sleeping and serene, and drank in the details of her beauty. Her eyelashes were so long that they cast shadows upon her smooth cheeks. Her lips were plump with a dreamlike softness. A soft smile crept across those lovely lips as she muttered something he couldn’t quite comprehend. The elegant slopes and curves of her body... the heaviness of her breasts that hung underneath the sweater she wore.

The thought of them got him going properly now.

Images of him tearing off her clothes and kissing every inch of her body and worshipping her properly flashed in his mind. Thoughts of him rubbing his aching cock against her porcelain skin and staining her with another shade of white soon followed. Then came the lurid dreams of her dripping cunt enveloping his prick...

He couldn’t.

He wouldn’t.

He did.

Carefully, oh so carefully, he laid Yor on her back, regretting it the entire time as it meant her delicious warmth and weight weren’t resting against his side. He fanned her beautiful hair out across the throw pillow and watched to see if she awoke.

Mercifully, she didn’t.

His pulse quickened as he hooked his fingers under her clothes, pulling and shifting them out of the way or entirely off. Every inch of porcelain that was revealed to him made him pant. Soon, he was like a dog in the hot sun. Pre dripped from the tip of his twitching dick.

His heart hammered inside of him as dozens of fantasies flashed through his mind. They were all going by so fast that he couldn’t even make sense of all of them. He wanted to rub his cock against every nook and cranny of her body. He wanted to kiss and lick and nuzzle every inch of her. He wanted to make her fall apart at the seams, show her pleasure that that bastard Forger could never give her. He wanted to fuck her. He wanted to breed her.

Sucking in a deep, shaky breath, Yuri calmed himself. Or tried to anyway. He couldn’t let himself get too out of control. It wasn’t like Yor was drugged or in a coma or something. She could wake up at any point. As enticing as the thought of her waking up right as she orgasmed and seeing him be the reason why she came was... it was too likely that she would despise him.

He wouldn’t be able to take that.

The world meant nothing to Yuri Briar if his sister hated him.

He swallowed as he looked her over. His shaking hands hovered above her heavenly body. He was scared to actually touch her. What if this was all some dream that’d end as soon as he laid his disgusting hands on her? Would she crumble into dust? No, she had hugged him earlier. She didn’t collapse or turn into ash. It’d be OK. He just had to commit. He had gone this far already. It’d be OK.

Finally, he stroked her cheek. His thumb swiped just below her eye before he dragged his hand downward. Down the slope of her pretty neck, her shoulders and upper arms which were firmer than he would have thought, before lacing his fingers with hers. He brought her hand to his lips and kissed the tips of her digits, her knuckles, her palms, and wrists before slipping her fingers into his mouth. The taste of rose-scented lotion stained his palate but he didn’t care. His tongue swirled around the slim, delicate finger as her short nails scraped against the sensitive roof of his mouth before he suckled around the base. The sensation of her wedding ring was unpleasant in every sense of the word but he couldn’t risk taking it off and losing it. She’d wake up and notice something was up. With a lewd ‘pop’ that almost echoed in the quiet apartment, he pulled his lips from her. Panting, he watched her sleeping expression to see any sort of reaction.

Nothing. She didn’t even scrunch her face in what was surely a cute way.

Emboldened, Yuri gently placed his sister’s arm back on the couch and dove in for a kiss. His hair framed their faces as his lips clumsily mashed against hers. It wasn’t the kiss that he always dreamed of giving her but he poured every drop of his love, his soul, his everything into it. His hands ran through her hair before going down to grope her supple breasts. The firm softness that his fingers sank into was everything that he had wanted. Her nipples—large and dusty pink—bit into his palms. Whether or not she was aroused or she was simply reacting to the semi-cool air of the loft was a mystery that he didn’t care to solve. He pulled away from the kiss only to dive back in and smother her lips, nose, eyelids, and cheeks with dozens of butterfly kisses.

Oh, he loved her. He loved her so, so, so much.

Panting, he pulled away again but kept his hands on her breasts. Her marvellous breasts. He watched as his fingers sank into the soft flesh. How they wobbled in his grasp. How she did huff and shift ever so slightly when he teased the stiff buds. He huffed. His cock jumped as he pinched her nipples and heard her groan. He held his breath and stopped. She stirred and relaxed. Unable to take it anymore, he captured one of her nipples between his lips and gave a harsh suck. His tongue ran circles around it and flicked it between sucks. Precum dribbled freely from his cock and seeped through his underwear and surely through his slacks. Reluctantly, he moved his left hand from her breast and groped himself through his pants.

He wanted relief. He wanted it almost as badly as he wanted her.

One final suck was given to her before he pulled back to undo his pants and release his dripping cock. It bobbed once it was free. His essence rolled from the tip and dripped onto the upholstery. Whatever, he didn’t care. He simply was incapable of caring at that moment.

He stroked himself as he watched her sleeping form. Each stroke sent flecks of pre flying across her body. Every bit of her was absolutely erotic. The curves, the way the light hit her soft skin, the way her chest rose and fell with every deep breath, the way saliva dripped from her open mouth as she slept...

Once more, he kissed her lips before swiping his tongue across the rivulet of drool and savoured the taste. He shuddered. Divine. Absolutely divine. He hungered for her. His body ached for her in a way that reminded him of a deep, dry thirst that could only be quenched by ice-cold water. Huffing, he pulled himself off the couch and readjusted her body so that she was sitting up against the backrest.

He parted her legs, taking note of how her trim thighs still squished and spread across the seat, and stared at her bare mound. He wondered if he could get away with pocketing Yor’s panties on his way out. It’d be a reminder of this night. Something tangible. A souvenir. Swallowing, he leaned forward to get a closer look at her cunt. Thick, unruly pubic hair greeted him. Hesitantly, he parted her lips and drank in the rich sight of her deep, healthy pink folds, clit, and twitching entrance. The heady scent of her sex flooded his senses. It flipped a switch in his head and he was unable to take it anymore.

Like a beast with a ravenous appetite, Yuri dove his face into his sister’s cunt. His lips smashed against hers as his tongue ran along her slit. He had no finesse. No technique. It was all about devouring her. She tasted so human. So real. The tang of her arousal that dribbled onto his eager tongue and lips only fuelled him further. His hands gripped onto her thighs as he noisily drank from her cunt. He shuddered as the now slippery with slick textures ran along his tongue. He dragged his tongue from her asshole, taint, and then to her clit.

Tremors wracked his body as sheer pleasure pulsed through his body. He wasn’t touching himself. Yor wasn’t touching him either. Just the fact that he was able to touch her, taste her, smell her, look at her, and experience this with her at all was enough to make him want to cum.

He wasn’t going to though.

Not until he got Yor to cum first.

Hungrily, he kissed her slit. Her pubic hair tickled his face as he pressed himself firmer against her. He kissed her once, twice, three times before suckling on her clit. Suddenly, Yor let out a noise that could only be described as a gasp and a high-pitched whine, as she writhed above him. He heard her breath quicken as juices gushed onto his eager lips. The taste and scent of her was so strong. He was going crazy!

More. More. More!

Yuri wasn’t even the one being pleasured but he swore he could feel how good Yor did at that moment. Every sound, every movement, every pulse of her cunt, it drove him mad. Soon, he didn’t even care about her waking up. He just needed her to reach her peak. To shower him with her pleasure.

Small, almost pathetic whines slipped from Yor’s drooling mouth as her brother worked her clit. Her toes curled and her hips squirmed and bucked against his damp face. Sweat rolled down her face as her arousal gushed onto the couch. She trembled violently as her clit continued to be assaulted. Her cunt spasmed around nothing as even in her sleep, she felt an ache rumbling inside of her core. Pressure built itself inside of her. One white-hot that burned the bottoms of her feet and made her muscles spasm as it continued to grow and grow. It wasn’t one she was super familiar with. She had experienced it a few times at her own hands. She didn’t let other people touch her. The other pressure, one she knew all too well, lapped at her insides. It sloshed inside of her with every movement she made. The muscles in her groin clenched as she felt something suck around and bounce against her most sensitive of areas. Her squirming only got worse as that pressure continued to ebb throughout her lower half.

Yuri pulled his mouth away, strings of saliva and her slick connecting them, and panted. He licked his lips, causing the strings to snap between them, as he stared up at her sleeping face. Her eyebrows were furrowed and her teeth ground against each other as her hips desperately bucked against the air. His hands shook as he pulled one away from her thigh and slid it between her legs. The pad of his middle finger ran along her folds before tracing along the twitching entrance of her cunt. His breathing slowed as time seemed to stop. Then, he pushed it inside of her. She was so hot and so wet that he sank to the last knuckle easily.

He was inside of her. He was inside of his sister!

A maniacal grin split itself across his face as he slipped another finger inside and then another one. His cock ached as he imagined this velvety heaven enveloping it instead of his fingers. The other hand slipped downwards to grip his cock. He stroked himself madly as he tried to thrust inside of Yor at the same time. The rhythm was off and all over the place but he didn’t care. Yor probably didn’t either. His fingers stretched her wide as he stroked her sensitive and unknowingly pristine walls.

He looked up at her again, watching for any sort of reaction in case he needed to stop. That was, if he was capable of stopping. Then... her eyes fluttered open for a moment and he felt his heart stop. Ice water pulsed through his veins as his sister’s wine-coloured eyes locked with his own... and yet his fingers continued to move.

“Y-Yuri?” she mumbled sleepily.

“Go back to sleep,” he muttered in a panic.

She stared at him a little longer before closing her eyes. “But... I... Need to...”

Then, she was out.

He huffed as adrenaline pulsed through his veins. Sweat rolled down his flushed face as he buried his fingers as deeply inside as he could get. A voice in the back of his head told him to pull out and fill her properly. Fuck her. Fuck her and mark her as his. Impregnate her and have that bastard Forger have to deal with the fact that Yor had his kid and not his. He wanted this. He oh-so-wanted this so badly. But he couldn’t. He couldn’t do that to Yor.

Gritting his teeth, Yuri pumped his cock madly as he imagined how good she’d feel around him. She felt heavenly around his fingers. Slowly, he stood up and slid his fingers outside of her—unknowingly making her feel woefully empty in the process. His thumb bumped against her clit and rolled it around in circles as he jerked off above her. Once again, flecks of precum flew onto her thighs and seeped into her pores.

A keen slipped past her lips as pressures continued to build and build inside of Yor. It was too much. So, she came.

A gush of urine splashed against Yuri’s hand as her cunt clamped tightly around nothing inside of her. It was a short, almost abortive, gush. One that her body desperately tried to keep inside.

Yuri knew that something was wrong with him long before this night but the sight of his big sister pissing all over his hand made him feel something. He should have been disgusted. He should have stopped. But he didn’t. He wanted more of it. He wanted to see Yor completely debase herself.

He ground his thumb against her clit like a madman. Part of him knew that this probably was unpleasant but he wasn’t willing to stop. He needed her. He needed to see more of it. He needed to feel more of her piss. More, more, more. That was all he could think of.

Another spritz of piss splattered onto his and the floor in golden droplets. Then another and another before she finally came undone. A long, drawn-out cry escaped the sleeping woman as piss sprayed across the couch, floor, and Yuri’s pant leg. The pressure in her full bladder eased as her brother drained her.

The air smelled heavily of piss and sex and Yuri didn’t care. At least not at that very moment. It was all because of him. He reduced his sister to such a state. He doubted that Loid could ever do this. The man couldn’t even call home to say he was going to be late. He doubted that he even touched his sister. Sure, Yuri couldn’t stand the thought of the two kissing but he knew, or rather he hoped, in his heart of hearts that he was right and he was the only one that got to see Yor like this.

Eventually, the stream of piss slowed to a trickle and then a few drops.

His thumb dragged itself downward and pulled her labia to the side to reveal her slit once again as he stroked himself off once again. His eyes flickered to Yor’s face once again before staring at her dripping cunt. His hips humped his hand as he imagined flooding her with his seed.

Then, he came.

He shuddered as his orgasm ripped through him. Cum splattered across Yor’s body and painted it a milky white. The furthest load reached just above her navel while the rest of it landed on her thighs, pubic hair—where it contrasted prettily against the stark black—and her spread pussy.

Yuri huffed as he wiped the spatter off her lips and onto his already ruined pants.

A moment passed before he realized what he just done. Guilty panic shocked through his system as he rushed to clean up the literal mess he had made. The heady scent of sex and urine hung in the air as he pulled the somehow still sleeping Yor into his arms and led her to what he believed was her and her husband’s room. Delicately, he washed her thighs, hips and wherever else he could think with a damp wash cloth and yanked a nightgown over her head. He was in such a rush that he didn’t notice the distinct lack of frilly, over-the-top lovey-dovey decorations that were there the first time he visited. The room was... passable after a few moments with the windows open and one of her perfume bottles practically emptied to try to cover up the smell.

Then he left.

The next morning, Yuri awoke to the sound of his phone ringing. Guilt hammered inside of his chest when he heard Yor’s sweet voice on the other end. She apologized for falling asleep on him and then asked if he helped her get to bed. He answered... sort of truthfully. He did do that.

“You were just too tired to remember changing, I think,” he said as he gripped his thigh.

“That makes sense...” she said with a small laugh. “I... I feel. Never mind.”

“What’s wrong?”

“I had a strange dream about you is all. It doesn’t mean anything. Well, I don’t want to keep you, Yuri. Thank you for helping Miss Anya yesterday. Would you mind coming over again next week? Mr. Loid is going to be out for work... and you know I’m not good with helping with that sort of thing.”

Yuri swallowed. “...Sure, perhaps I could stay the night then.”

“That’d be fantastic! I’ll see you then. Goodbye, Yuri!”

“Goodbye, Big Sister,” he muttered before hanging up. He had gotten away with it and could perhaps, get away with it all again.
