Kinktober Day 4 - Hate Sex

Sanemi X Fem!Giyuu

A/n: Ngl, this is one of my favorite stories i've written for kinktober. I need to write hate sex more often, it is so fun! Also sorry for the radio silence on here, I've moved to a new county so XD A touch busy with life. But anyway, enjoy!

Gluck glurck gluck.

Sanami laughed as the filthy sounds echoed throughout the air, tossing his head back as he took pleasure in the situation. He always loved it when he won the bet, his pride swelling as he got the bratty woman to submit to him.

Giyuu was between his legs, her pretty pink lips stretched around his cock, a blush on her face as she deep-throated him. His cock was drenched in her saliva, dripping down his balls and making a mess of the mattress he was reclined on, but Sanemi didn’t mind. Was it truly a good fuck session if the sheets didn’t need changing after? Leaving her dressed in only her panties and her top, he got quite the view from where he sat, her perky ass perched up in the air as she bent on her knees to suck him off. He was completely naked, enjoying the power as he got to order her around the whole night.

The black haired woman glared up at him as she heard him laugh, her blue eyes would have been intimidating were it not for her dilated pupils. She pulled off of his cock, a string of saliva connecting his cockhead to her lips for a second before it broke apart. “Don’t act so fucking smart.” She said, cursing at him even as she jerked his cock up and down. “Why not?” Sanemi retorted, always enjoying when Giyuu was a mouthy brat at him, “Actually, be a good girl and remind me what the price of winning the bet it?” She simply clicked her tongue, averting her gaze from his prideful smirk. But of course, Sanemi wasn’t going to just let her be. His hand shot out to grip her face, squishing her cheeks together and forcing her lips to pout, making her face him. “I asked you a question.” The man growled, pressing on her face tighter, “Where’s my fucking answer?” Giyuu whined, trying to break away from his grip but failing. She huffed, the action looking quite adorable with her pouty face, before she answered:

“Whoever kills the most demons submits to the other for a day.”

“Exactly.” Sanemi said, pushing her face a bit as he let go, “Now enough with the attitude and get back to sucking.”

“You’re an asshole.”

“And I’m going to fuck yours with no lube if you keep running that mouth of yours.”

With another click of the tongue, Giyuu once again placed her mouth on his cock, Sanemi tossing his head back as she started taking him in again. He got comfortable against the headboard, his hand coming up to grab the base of her ponytail, ignoring her whine of protest as he helped her deep throat his cock once more.

He disliked Giyuu the second he met her. Sure, she might have been a Hashira for a bit longer than him, but her high and mighty attitude mixed her with a sarcastic tongue quickly put her on his shit list. Sure, he might have thought she was beautiful, with her dark raven, spikey hair put up in a ponytail and her deep, blue eyes but her looks weren’t enough for Sanemi to like her. And it was no surprise that she wasn’t quite fond of him either.

Giyuu disliked Sanemi the second she met him. Not only did he snap at Ubuyashiki, but he was also violent, loud and had a short temper- all attributes that she did not have the patience to deal with. Sure, she thought he was handsome, his stark white hair and his piercing eyes which she found to be attractive rather than scary and not to mention the scars on his toned body that made him even more manly- but his looks weren’t enough for Giyuu to like him. And she didn’t care that he disliked her too.

But it was after a drunken night where everyone was tipsy from the alcohol, that their little bet first came to fruition. The rest of the Hashira were either passed out or flat out drunk, Sanemi and Giyuu being one of them. With one brash insult after another, the two of them were close to fist fighting were it not for Uzui stopping them:

“Shame on you, Sanemi!” the man said, loud and drunk, his words slurring, “No man should ever- ever fight a woman!”

“She’s not a woman.” Sanemi responded with a sneer, “She’s a rabid bitch!”

“And you’re a pissy little cow who throws a temper tantrum every time something doesn’t go your way.” Giyuu retorted, “even babies are more mature than you are.”

“The fuck did you say?!”

“Now, now.” Uzui said, trying to calm them down by ruffling both of their heads, “let’s not fight. Both of you are frustrated with each other and there’s a very simple way to resolve this tension.” He paused, making sure both of them were listening before he continued:

“You just have to fuck it all out.”

“What?” Giyuu asked, “HUH?!” Sanemi barked.

“You two always butt heads and it can be solved if you just fuck.” Uzui continued, taking another shot, “Trust me, a long night of rough sex is the perfect remedy.”

“Hah! Like I’d ever sleep with this pig.” Giyuu snapped, “I bet he’s not even good in bed.”

“Please- My dick works just fine as long as I’m sleeping with a beautiful woman and not some witch that was fished out of a well!”

And thus, the bet was born. Whoever got the most kills on a mission would be in charge in the bedroom and fuck the other however they please. Sanemi won the first round and he couldn’t be happier rubbing it in her face, the man going wild as he fucked her, insults and curses spewing from both their mouths. It was a fun and intense night but it proved Uzui wrong. It didn’t resolve anything- but rather- made them even more competitive.

Giyuu demanded a rematch. Which she won. So Sanemi demanded a rematch but Giyuu won again. So he demanded another. And then she demanded another. And she wanted a rematch after that one and well- now they’re here.

“Fuck yeah,” Sanemi growled, fucking Giyuu’s face mercilessly, his hips leaving the mattress to fuck into her mouth, “That’s it- take it- take it you nasty bitch!”

Giyuu couldn’t even glare at him, her eyes watering as his cock slid down her throat over and over again, her gagging adding more pleasure. His grip on her hair was unrelenting, using her mouth like a toy as he mercilessly pounded into her, his balls slapping against her chin. Giyuu assumed she’d be used to the sensation considering the number of blowjobs she’d given the man but, apparently not. Sanemi had a deliciously big cock (not that she’d ever tell him that) with a long, thick shaft and an angry red head with heavy balls. The first time she saw him, hard and dripping with pre-cum, she had to try her very best to not look fazed, lest the man get an ego about it.

“G-Gonna cum!” Sanemi moaned, tossing his head back, eyebrows furrowed as he felt the tell-tale signs of an orgasm rush over him, “Swallow every drop like you fuuuucking love it!”

Giyuu groaned around him and that just increased the pleasure, his balls clenching as he got ready to unload. A couple more thrusts and a loud shout later, Sanemi climaxed. He moaned loudly, toes curling and eyes rolling to the back of his head as he came, pulling at Giyuu’s ponytail and keeping her flush against his abdomen. Cock shoved deep, deep down her throat, her fingernails digging into his thighs, Giyuu gagged around Sanemi’s cock as he came. Rope after rope of cum shot down her mouth, her throat constricting around him with each gulp, the man so far down she could barely taste him.

His balls throbbed with each pump, Sanemi lightly rolling his hips against her as he milked his dick for every drop, letting out a satisfied sigh as he watched the woman take him so perfectly. “There we go…that’s it…yeah, you fucking love it~”

She couldn’t help but roll her eyes as Sanemi eventually let go of her hair, strands of it having been pulled out of her ponytail. She gently detached herself for his cock, leaving behind a sloppy, slobbered on mess. His dick was still hard, needing several rounds before it went limp thanks to his line of business and the stamina he built. Not that Giyuu was complaining of course.

“So full of yourself.” She teased, giving him another eye roll. “Oh yeah? Then maybe don’t enjoy it so much.” Sanemi retorted. “You think I’m enjoying this?” “I do. But please, take those panties off and prove me wrong.”

Giyuu pouted, knowing full well that her panties were drenched, her pussy dripping. Sanemi laughed, giving her a light pat on the face, “That’s what I fucking thought. Now show me those tits.” Still pouting, Giyuu straightened up and sat on her heels, fingers getting to work on her uniform. Sanemi continued to recline against the headboard and enjoyed the view, peeks of her skin getting revealed as she unbuttoned her top. So many people in the corp were head over heels for Mitsuri, Sanemi having to scare of many a perverts to keep the pink haired woman safe as the Love Hashira was too nice to actually hurt humans. But he always thought people were blind for not realising just how sexy Giyuu was.

An ample chest, toned body with beautiful curves and a nice ass- she was stunning. Not that he’d tell her that, of course.

“You’re staring like an old pervert.” Giyuu said once she tossed her top and bra aside, her bare breasts out for Sanemi to enjoy as she crawled towards him, already knowing what he wanted. “Yeah, well.” The man said, eyes indeed glued to her breasts, plump with cute, pink nipples that were already hard as she sat on his lap, straddling him, “You’re good for something.”

“I can say the same thing about you.” Giyuu said, grinding her panty covered pussy against his cock, making him hiss at the sensitivity. He smacked her ass harshly, making her gasp from the contact, the pain getting dulled as he grabbed a handful of the cheek he just spanked, groping it like a toy. Two fingers slipped into the fabric of her panties, caressing her soft skin, inching closer and closer to her wetness. Deciding that he wanted boobs more than to retort, he simply ignored her comment in favour of opening his mouth and sealing his lips against the tit that was right in front of his face.

Giyuu bit the inside of her cheek to prevent herself from moaning, refusing the let Sanemi know just how sensitive her breasts were- or rather- just how good he made her breasts feel. The way he sucked at her nipple was addicting, his hot tongue running over the hard bud in circles before flicking it mercilessly, each flick making her body shudder. Her hands ran up his shoulders to clutch at his hair as he suckled on a nipple, his long eyelashes tickling her skin as she grabbed onto fistfuls of his silver locks.

“’Not enjoying this’ my ass.” Sanemi growled as he pulled away from her nipple with a pop before running his tongue over her breasts to make his way to the other bud, “I’m not even touching your pussy but I can feel how wet you are.”

“Sh-shut up- ah!” Giyuu gasped as he licked at her other nipple, giving it a gentle nibble before wrapping his lips around it and suckling harshly. All the while, without her knowing about it, her hips were grinding against him, her body aching for pleasure. She hated that he could see right through her, but she did get turned on by sucking his cock. No- she was turned on the second he got her in his room. Pushing her in, ordering her to strip while he took his clothes off- the passionate way he kissed her before pushing her onto the bed-

“Sa-aah-nemi.” She called out with a gentleness he rarely heard from her, the woman tugging at his hair, “I- fuck- I want a kiss.”

“Hmm? What was that?”

“Y-You heard me, asshole.”

“Fine. Have it your way.” He sucked on her nipple again, ignoring her request entirely which made her groan in frustration. “Fuck- fine- I- I want a kiss.” Giyuu relented. “You want to kiss me?” Sanemi asked, flicking her nipple with his tongue and loving the way she jumped. “Y-Yes. I do.” “Then kiss me, bitch.”

He grabbed her by the back of her head and roughly pulled her down, making Giyuu yelp at the sudden movement. He crashed his lips against hers, immediately slipping his tongue in and swallowing her little moans. He loved it when he got her like this. Needy and desperate with just enough attitude to make things fun. She moaned against him as he continued to grope her butt, her pussy grinding against his cock shamelessly, her cute whines for more was music to his ears.

“Ah-ah!” she squealed, feeling dizzy as Sanemi’s hand slipped into her panties just as he started biting her tongue. She could feel him snicker as his rough, thick fingers touched her bare pussy, the sound of his digits rubbing against her wetness already loud. He rubbed at her clit, giving it quick strokes before rubbing rough yet slow circles on her sensitive bud. Oh he couldn’t wait to get his mouth on it, but that would come later. For now, he wanted to move on with the main course.

Giyuu pulled away from the kiss to moan, overwhelmed by the sensations as Sanemi suddenly slipped two fingers inside her, her pussy so wet he didn’t need to work up from one. He watched as she rested her head against his shoulder, his other arm wrapping around her waist as he fingered her open, her juices dripping down his hand.

But he wasn’t going to let her off that easily.

“What was it you did the last time you won?” Sanemi asked, a knowing smirk on his face as he pressed a kiss to her shoulder, “Oh, that’s right. You tied me up, rode my cock and came over and over again- but you didn’t let me cum even once.”

“That’s-“

“And what was it you called me? Your personal dildo?”

“Uh-“

“Now, convince me.” Sanemi said, stopping his fingers as he looked up at her, nudging her so she’d move her head from his shoulder, “Why should I let you cum, hmm? Right now, you’re my personal pussy and do toys deserve to feel good?”

Giyuu bit her tongue before an insult could escape, Sanemi’s hand on her hip preventing her from grinding against his fingers. If she wanted release, she’d…have to submit.

“I-If you let me cum- I’ll let you cum inside me.”

“I was going to do that anyway.”

She mewled as Sanemi started to lightly thrust his fingers, not moving enough to truly give her pleasure, but enough to remind her of her fingers stretching her pussy and that his cock would feel even better.

“Y-You can fuck my ass?”

“I think you’d enjoy that more than I will.”

She bit her lower lip, gnawing at it before she threw away her pride and said:

“Th-Then…the next time we bet…we’ll consider you the winner.”

Sanemi raised an eyebrow, a smile on his face, “Three times.”

“Two. Take it or leave it.”

“Oh, you think you’re in a position to negotiate?” Sanemi asked, curling his fingers just right inside her, hitting her g-spot and making her gush like a fountain.

“F-Fine! Three times! The next three bets- you’re the winner.”

“You better not fucking forget it!”

Taking his fingers out of her, Sanemi pushed her, both of them tumbling into a new position. Giyuu grunted as her back met the mattress, her legs spread wide for the white-haired man to tower over her. His hands grabbed at her panties and pulled them apart, ripping them like paper. She had to remember to chastise him for ruining another pair of her undergarments but for now, she was too desperate to care.

Sanemi licked his lips as he grabbed her legs and spread her apart even more, his dick twitching with excitement as he gazed at her pussy. Perfect, juicy and oh so fuckable, he had spent many an hour eating her delicious cunt and even more time stuffing his cock inside it. He gripped at his member, giving it a few tugs before he placed it at her entrance. Giyuu watched, excited as both of them didn’t care for words anymore.

She gasped as he started to push in, his fat cock splitting her apart deliciously. She’d never get used to his girth inside her and Sanemi would never get used to her tightness. He grit his teeth to stop himself from moaning as he pushed inside her, her pussy so wet the glide was smooth and so, so deliciously hot. Eventually, he bottomed out, both of them gasping and panting like virgins doing it for the first time.

Seeing Sanemi on top of her, the mans face flushed red and eyebrows furrowed, clearly overtaken by pleasure was a sight for sore eyes. Sure, it was fun seeing his hungry expression as she ordered him to eat out her ass or the frustrated look in his eyes as she rode him without giving him release- but she might enjoy this a bit more. She wrapped her arms around his shoulders and her legs around his waist, pushing him even deeper inside her and making both of them moan as his cock touched the entrance of her womb, her body aching for more.

And more he was going to give.

With a grunt, Sanemi started to thrust, muscles tightening as he worked his body the way he knew she liked. With her gummy walls milking him, he rolled his hips against her, smirking triumphantly as she let out a sweet moan, letting him know he found her g-spot. Aiming for that spot inside her, he picked up the pace, snuggling his face into her neck as he fucked her- no- as they made love. “S-Sanemi- Sanemi!” Giyyu screamed, balls slapping against her as he pounded into her, his cock leaving her breathless, “Yes- yes- oh yes!” “Yeah, scream for me baby~” Sanemi cooed, not missing the way her pussy tightened around him as he called her the adoring nickname, “Milk my cock like a goooood fucking girl~ You like my cock? Hmm? Oh, you love it, don’t you?”

Ever defiant, Giyuu shook her head, making him laugh out loud but this time, she laughed with him, even if her laugh was jumpy due to the force of his thrusting. “Th-there’s n-no way your c-cock will- oh fuck- hnng- make me feel g-good!” “No way huh?” Sanemi asked with a snicker, knowing the woman was full of shit, “Then should I stop?” “No!” Giyuu protested, eyes wide as she wrapped her arms around his tighter, “No- No please-“

“Then beg me for it.” Sanemi snarled, looking her right in the eye, sweat dripping down his brow as he continued with his pace, “And- fuck me- apologize.”

“I-I’m sorry for l-lying.” Giyyu said, tears in her eyes over the pleasure, feeling his cock throb inside her, “I want you- I want your cock to f-fuck me silly!”

“Good girl~” Sanemi pepper her cheek with a few kisses before he took her lips again, picking up the pace of his thrusting. Giyuu dug her nails into his back, leaving behind bright red marks- scars that he’d wear with pride. There was no more talking- just lust. The room was filled with the sound of skin slapping against skin, of moans, of cries and of kisses, both of them going dizzy from their desires.

“G-Gonna cum!” Giyyu whined, panting heavily, feeling like she wasn’t taking enough air into her lungs from how much Sanemi had ruined her. She didn’t know how much time had passed, but she didn’t care. All she wanted was him. “Me too!” Sanemi said, his hips almost a blur with how passionately he was pounding her pussy. He was determined to make her unable to walk tomorrow, “Fuck- fuck! Cum around my cock, baby~”

“Cum inside me!” Giyuu begged, tossing her head back as her tits bounced up and down, Sanemi occasionally taking a greedy grope, “Want you- inside me.”

“Fuck- cumming!”

“Cumming- cumming!!”

With a scream, the two of them climaxed simultaneously. Giyuu screamed, eyes rolling to the back of her head and her back arching in a perfect ‘C’. Her muscles tensed and her toes curled, her legs shooting out straight and her fingers digging even harder into Sanemi’s back. Her orgasm hit her like a truck, taking away her breath as all she could do was cry and moan, her body trembling like a leaf. She giggled happily as she felt him cum inside her, pumping her womb with his seed. He filled her up deliciously, Sanemi always cumming gallons. He came and came, filling her up so much she felt him spill out a bit. Sanemi wasn’t any better. The man bit into Giyuu’s neck, marking her as he moaned into her skin, the slightly pain turning into her pleasure. His balls clenched as he shot out ropes of thick, hot cum into her eager cunt, filling up her baby maker. Was it risky? Absolutely. Was it fun? Absolutely.

Would Sanemi be upset if he got her pregnant? Absolutely not.

His body tightened, his muscles spasming as he came, hugging her tightly as he rolled his hips, pumping every last drop inside her of her, refusing to let any of it go to waste. Eventually, both of them came down from their highs, Sanemi completely collapsing on top of her once they were done cumming. Giyuu winced at the pain on her neck, grateful that the uniform would cover it up but that was a problem for future Giyuu. For now, she simply caressed Sanemi’s hair, his cock still stuffing her cunt as they returned back to Earth.

“That was…fuck…” Sanemi said, voice slightly muffled.

“That was great.” Giyuu agreed, pressing a kiss to his head.

“…finally got you to admit it.”

“I didn’t admit shit.”

“So you don’t want me to fuck your ass?”

“…I didn’t say that.”

“Of course not.”
