A/N: Aha, meant to upload this yesterday, but must've forgot... did a fair bit of writing so it probably just slipped my mind. Apologies~

Blowing Off Steam

Hunting Lamia could be bothersome at the best of times, especially the stronger varieties.

Hunting a Lamia who had sucked the mana out of numerous wizards and had, as a result, become immensely powerful and intelligent was quite the frustrating task indeed. From scrambling through brush trying to chase the sneaky snake attempting to both attack and avoid its retaliatory attack; it was an exercise in frustration. It wasn't even difficult per se, just frustrating as they tried, failed, and failed again to land a hit.

Mercifully the mission didn't last more than a few days, as soon they managed to corner the beast and, after a violent struggle, put it down with minimal injuries. Between Siegfried, Jeanne, Jack The Ripper and Yu Mei-Ren they were able to beat the beast down and overwhelm its regeneration ability; ending the mission and allowing the team to return to Chaldea practically unharmed.

''Haah...''

Ritsuka sighed as he meandered out of the teleportation room, tugging on his tight-fitting clothes uncomfortable. Fighting in a jungle had nothing but drawbacks, and the worst of them all was the wet heat in the air, leaving everyone sweaty and tired just by being there. The rest of the team behind him were similarly tired, slouches to their shoulders and all of them complaining about the heat, Siegfried suggesting showers and Jeanne mumbling about dragging Jeanne Alter to the nearest pond regardless of her sister's wishes – but the only one silent was Yu.

The dark-haired Master looked back at her. Yu met his gaze, silent even as she dipped her head in the shallowest of nods, prompting him to return the gesture and start walking off in the direction of the personal quarters. Moments later Yu caught up to him, speed-walking by his side – and the moment they were out of view from anyone else she grabbed his arm and dragged him, compelling him to speed up. Ritsuka didn't resist, following after the stoic Assassin as they made their way down the long, winding halls of Chaldea.

And soon reached his room. With an unchanged expression Yu came to a stop next to his room, giving him a disinterested look even as he unlocked said door and pushed it open – her brows raising somewhat when he boldly grabbed her hip and pulled her against his front, causing some pinkness to warm her cheek as he guided them both inside; shutting and locking the door behind them.

''Shower?'' Ritsuka murmured under his breath, all-too-familiar with their routine.

''Shower.'' Yu confirmed with a hum, still bearing a vaguely-disinterested expression.

With a smile Ritsuka complied, hand still around her waist as he escorted Yu towards the bathroom. The white-painted door was pushed open casually, revealing the white-tiled interior, his gaze sweeping over the basic amenities within, from the sink to the toilet – his gaze focusing instead on the shower at the far end of the small bathroom, slipping his arm out from behind Yu. Instead he stepped inside the shower stall and turned the shower on, uncaring of the cold water that sprayed over his shoulder and torso, instead listening in to the sound of ruffling cloth as Yu stripped.

He himself began to strip the moment he was sure the temperature of the water was good, the uncomfortable sweat only hastening his movements as he tugged his buttons undone and stripped himself of his outer layers, his undershirt soon following and tossed aside. Leaning forwards slightly he yanked his belt off and shoved his pants down, his underwear soon following and leaving him naked - tempting him to all but jump into the now-lukewarm spray of the shower, groaning as it washed away the icky sweat that had accumulated over three days of jungle Lamia-hunting.

''Move over.''

Behind him Yu joined him. Only then did he turn to face the beautiful woman, his eyes landing on her face before quickly and unashamedly dropping south, looking at her bare chest. Plump and round her breasts were emphasised by the arm she had slid under them, propping them up almost undoubtedly to get his attention. Yu didn't care for his staring, remaining unphased even when he kept staring, eyeing her from head to toe as she stepped up next to him and groaned, washing away the sweat too.

However neither had climbed into the shower together just to save water, and both knew it. Though there was no romantic feelings between them that didn't stop their basic needs, needs that they found best to simply solve with each other rather than deal with it themselves – it was practical, plain and simple. Thus it was with little hesitation that Ritsuka grabbed Yu by the arm and turned her to face him, and then shoved her up against the wall.

''Hey- Mmph!'' Yu's words were immediately quenched as he mashed his lips against hers, kissing her deeply.

The Servant melted into the sudden kiss, growling softly and grabbing onto his shoulders, digging her nails in. Ritsuka didn't mind, lust taking root in his mind and washing away any niceties – leaving sheer, unbridled horniness left. He didn't resist; eagerly giving into the carnal hunger within him and prodding at Yu's lips with his tongue, one hand rising up and grabbing her right breast, sinking his fingers into her plump breast roughly and hefting her tit about, relishing its weight.

Yu got him back, letting her lips part and inviting his tongue inside, only to bite his tongue. Grunting Ritsuka reared his tongue back and Yu capitalised on it, shoving her own tongue into his mouth and wrestling with his tongue, forcing a low moan out of his throat. The small cut on his tongue wept blood, the taste of copper rich between their tongues as they dragged out the heated French-kiss, dragging it out even as their lungs burned for more oxygen, one of her hands darting down and grabbing him by the balls, squeezing.

''Mn-!'' Ritsuka broke off the kiss, panting. ''Hah-''

He had barely drawn a breath before Yu grabbed the back of his head, yanking him into a kiss so roughly their teeth nearly banged together, muffling their mutual moans. She squeezed his balls near-painfully, prompting him to reach back and grab her ass, releasing it only to bring his hand right back down and spank her roughly, eliciting a gash from her throat. She took the hint and unhanded his balls, gripping his semi-erect shaft instead and jerking it short tugging motions, smirking into the rough kiss when he moaned.

Ritsuka retaliated swiftly, breaking off the kiss and burying his face into her neck, kissing it aggressively. The young woman moaned into his ear in retaliation, shuddering when his free hand slid down to her sex and rubbed it, fingers sliding along her folds passionately before jamming two digits inside her, making her hiss from the sudden entry. She endured it however, tugging on his cock as he paid her back in full with snappish thrusts of his fingers, getting her off.

''Hah, yes...'' Yu breathed heavily.

''Been needin' this?'' Ritsuka grunted questioningly.

''Mn.'' She jerked her head in a nod. ''Was planning on jumping you when we got the mission. Tempted when we had alone time in the jungle.''

''It was too hot there for that.''

''That's how pent-up I am, Master.''

Ritsuka just shuddered, easily able to imagine Yu stripping herself naked and straddling him, riding him despite the heat just to get off. The thought only fuelled his arousal, tempting him to slide a third finger into her snug sex and jam all three digits into her weeping slit, relishing the stiff moan he forced out of the Servant, his cock throbbing into her stroking hand. Scissoring his fingers apart earned him a spontaneous kiss, teeth soon sinking into his bottom lip and making him bleed; teeth digging deeper when he flicked her clit as payback.

''Nn!'' Breaking off the kiss Ritsuka mashed his lips against hers more properly, forcing her head back against the wet tiles from the intensity of it.

Yu moaned into the kiss, grunting when he yanked his fingers out – and shuddered at the feeling of both hands grabbing her ass, lifting her up. Yu was far from a heavy woman and he had quite a bit of strength of his own, allowing Ritsuka to bodily lift Yu up to eye-level and let her rest on his shoulder, his head between her legs; and without hesitation he buried his face between her thighs and buried his tongue inside of her.

''Mn! Fuck!'' Yu spat out, jerking her head back.

The curse rang through the bathroom, hot and violent. Ritsuka relished the sound and eagerly moved his tongue around her wet womanhood, slithering his tongue along her walls or wiggling it about, feeling her insides press down upon his wiggling appendage. Not a moment later a hand grabbed his head, slender fingers weaving into his hair and pushing his head deeper between her legs, groaning gutturally as he tongue-fucked her.

''Mn, hah... yes... use that tongue you mo- guh...!'' Yu gritted her teeth and hissed as his nose rubbed against her clit, pleasure making her tense up.

Ritsuka just hummed back, fingers digging into her ass as he held her up, eating her out with feverish passion. His tongue, skilled from many rounds of oral, expertly slithered around Yu's insides and lapped at her smothering walls, unrelenting in pace and tonguing out another hiss of bliss from her throat. She pulled on his hair and he replied by releasing her ass, bringing his hand back down before she could slip and spanking Yu's ass, earning a whispered curse from the Assassin.

Until with a low growl Yu pushed on his head, forcing his tongue out of her. Without missing a beat she wrestled herself out of his grip, back to the tile wall as she slid down it, his hands sliding along her slender body and shamelessly groping her breasts when he could. Yu didn't protest that, instead grabbing hiss erect cock and jerking him off. Her hand was soft and slender but her tugging movements rough and fast, jerking out a groan from his throat, unable to keep his voice to himself.

''C'mon.'' She growled, pushing her face in and planting a kiss on the underside of his cock.

Then with little warning Yu took his cock into her mouth, lips sliding over the head and engulfing his girth. Even as she roughly sucked back up to the tip and plunged herself back down again there was a bit of sensuality to her movements, teeth only just barely grazing his shaft as she sucked him off, saliva wetting his shaft and forcing a low groan out of his throat. Laying a hand on the back of her head he shoved her down deeper, grunting gutturally as he felt her tongue warm up the underside of his cock, his shaft grazing it as he pistoned back-and-forth.

A rougher shove made Yu deep-throat him, his cock shoved fully down her throat and his hand holding her down. She grunted wetly, throat convulsing around his shaft several times, before with a growl she bit his dick – teeth nipping dangerously at his shaft and making him loosen his hold on her. She slurped back up to the tip and popped her lips off, coughing raggedly and glaring at him even as she kept jerking him off, hand getting sticky with her own spit as it slid along his girth.

''Bastard.'' Yu snapped at him, taking the head back into her mouth – and shoving herself down this time, deep-throating him and roughly bobbing her head into his crotch.

Ritsuka groaned, planting both hands on the wall and watching her work. The shower's spray was warm against his right side but it hardly compared to the inviting warmth that repeatedly engulfed his cock, slurping up to the tip and then down to the base. Her movements were quick and passionate, her tongue not idle as it pressed against the underside of his girth or licked up the sides, the erotic movement coaxing out a strained hiss from his throat.

And when Yu grabbed him by the balls and squeezed, demanding he just cum already, he paid her back by shoving her head down his cock. The Assassin coughed around his shaft, unable to breathe with it down her throat, but he didn't hold her to his crotch and let her bob her head freely along his cock, moaning from the sensation. Adding to the erotic sight he got a good view down her front, his eyes lustfully watching as some beads of water ran down over her breasts or between them, her skin glistening wet.

''Mmph- hah...'' Yu pulled her lips off of his cock, panting. ''Pervert. Fine.''

Without needing to either ask or offer Yu sat up more on her knees, hands on her breasts – and with a slight bend to his knees he lined his cock up with her tits and slid his shaft between them. The feeling was lewd; her flesh wet and warm, amplified further when Yu deliberately pushed her breasts together and moved them up-and-down a little, the friction slight but the erotic motions pulling a groan out of him regardless.

''Ah, crap...'' Ritsuka breathed, cock burning and tingling as he held back his mounting lust.

''Cum.'' Yu demanded, glaring spitefully.

The anger, the disdain – feigned or not Yu looked downright sexy with such an expression on her face, his gaze torn between her irritated visage and her plump breasts as his cock slid between them, the shower's spray hitting the tip of his dick when it poked out from her cleavage and tickling his cock, hastening his end; and soon reached it.

''Mn!'' With a sharp grunt he rocked his hips back and stood up straight, hand grabbing his dick – before with naught but a flurry of quick strokes he came, blowing his load.

Yu got to feel it first-hand; thick, hot ropes of cum hitting her face. They splattered against her nose and lips, one long rope hitting her brow and dripping down over her eye, forcing her to screw her eyes shut. A wise move as it turned out as another rope hit her other eye, the milky load dribbling down her cheek whilst several shorter ropes hit her chin or fell short and landed on her breasts, his semen sticky and wet against her heaving tits.

''Mn... ah, hah...'' Slowing his strokes Ritsuka groaned, his orgasm waning.

Shuffling slightly to the side Yu stuck her head directly under the spray of the shower, grumbling something incoherent as she washed away the cum in her eyes, allowing her to actually open them. Putting her feet beneath her the Assassin stood, her slender frame slick with water as the liquid ran down her toned back or over her curvy hips, the sight too attractive for Ritsuka to resist – his lust far from satiated by a single orgasm.

Thus with little hesitation he pushed Yu against the wall. Yu grunted, cheeks flushing a dark red hue as he guided his cock down and slid it between her thighs – his hips lustfully bucking forth and plunging his cock between her thighs, fucking them. The lewd feeling only embarrassed Yu more, a growl of annoyance escaping her, but he prevented her from resisted by pinning her wrists to the wet tile wall, his breath hot against the back of her neck.

''Just stick it in already.'' Yu hissed at him, breathing heavy as she felt his cock rub against her folds slightly – not enough to get her off, but enough that she couldn't ignore it.

In response Ritsuka pulled back, cock pressing flush against her ass for a moment before he whisked her around to face him, pinning her to the wall. Growling Yu hopped off the floor and wrapped her legs around his waist, one of his hands reflexively grabbing her ass to hold her up while his other guided his cock to her wet entrance, pushing in – and Yu spat out a sexy curse as he penetrated her. She was tight, even more so with how tense she was, but the tightness just encouraged him to pull her down onto his cock, forcing himself into her.

''F-Fuck...'' Yu grabbed the back of his neck. ''Fuck me.''

Without another syllable hissed she yanked him in, mashing her lips against his. Ritsuka groaned into the feverish kiss, pushing her sweaty back against the tile wall before pulling his hips back, the motion preluding that of his cock spearing back into her clenching tightness. She felt so hot that he drove himself into her eagerly; cock prying her tightness apart and hitting her deepest parts after just a scant few thrusts, fucking out a string of jerky, breathless curses from Yu, the sound muffled by the kiss.

Keeping just one hand on her rear Ritsuka snapped his hand up, grabbing her right breast and squeezing her plump tit, fingers sinking into her doughy tit. She growled and paid him back by grabbing his hair, pulling it roughly as they kept making out; lips parting only long enough to suck in some much-needed air before they went right back to making out, tongues getting involved with a growl. Yu took the lead with it, tongue shoving itself into his mouth and wrestling with his, but experience let him fight her tongue out and wrestle with it being their mouths, their mutual groans lost to the spray of the shower.

''Mm- haah!'' Yu exhaled sharply as she broke off the kiss, glaring spitefully at him. ''This all... you got?''

In response he unhanded her breast and brought it down on her ass, spanking the Assassin. Yu tightened sharply around his girth and groaned gutturally, her dark eyes alight with carnal need, her legs wrapping around his waist to make sure he wouldn't pull out. Given her nature as a Servant the risk of her getting pregnant was practically nil, giving him all the reason he needed to blow his load inside of her; the thought igniting a primal arousal within Ritsuka, his pelvis smacking against hers as he railed her raw.

Yu grunted sharply, grabbing his shoulder and digging her nails in, drawing blood. Ritsuka hissed and spanked her as payback, gazing into her glaring eyes as he pounded her – taunting her by leaning in for a kiss but leaning away when she did, earning a snarl from Yu. She pulled his hair but he refused, lips coming ever so close to hers but denying her the pleasure of a kiss, leaving her to content herself with the cock that plunged between her lower lips.

Until soon she employed some of her superhuman strength, yanking his head in and mashing their mouths together, banging their teeth together from the sheer roughness – neither caring in that instant. Ritsuka groaned and groped her right tit, squishing her plump breast beneath his fingers and ramming himself into her harder, forcing his hips to slam forth as roughly as physically possible; the ensuing smacks of flesh carnal in their intensity and bouncing off the walls of the bathroom, echoing in their ears.

''Hah, fuck...'' Ritsuka grunted against her lips, the inviting heat smothering his cock melting his mind. ''Gonna cum.''

Yu growled. ''I'm not close yet.''

Ritsuka just pinched nipple, earning a hiss from the Assassin. ''I'll finish you afterwards.''

A snarl answered him, the sound muffled as Yu yanked him into another kiss, her back arching slightly as he kept pounding her pussy, the engulfing heat becoming too much for him to resist – his shaft aching as he held back the urge to just blow his load. However he was left too sensitive after her blow-job, unable to hold out as long as her. And soon he reached his limit, the heat rushing up his cock intense and raw.

Before with a gasp he slammed into Yu and came. Her walls tightened up around his girth, pressing down and squeezing out thick ropes of semen that splattered deep into her; several slow, jerky thrusts slamming his cock in and fucking out stiff moans from Yu, their lips sealed together as he climaxed inside of her. She raked her nails down his back and rocked her waist, wringing as much of his seed out of him as possible.

And at last with a gasp they broke apart, panting heavily. ''Hah, haah...''

Ritsuka rocked his waist, hissing as he slowly pulled out of the Assassin. She loosened her legs and let him pull out fully, his cock slipping out of her tight sex – her feet touching the floor as he lowered her back down. Yu still glared at him but was too out-of-breath to speak, taking a long few moments to just breathe, before soon turning her back on him and planting both hands on the wall, presenting her ass to him.

He knew an invitation when he saw one. Groaning he grabbed her hips and pressed himself flush against her ass, grinding on her rear as he got himself rock-hard for her again – high mana reserves helping with that, his dick soon returning to its fully-erect state after just a bit of grinding. Yu huffed at that and leaned forwards more, arching her toned back and waiting for him to finish her off, impatient... only for her eyes to widen when he lined up with her asshole.

''Hey, wait- Mmph!''

Pursed lips muffled Yu's sharp, throaty moan as he so suddenly pushed into her asshole; cock sliding into her tight hole slowly but firmly. Behind her Ritsuka let out a moan of his own, the ungodly tightness of her ass only encouraging him to start moving right off the bat; hips rocking and pistoning his length in-and-out of her, his slow thrusts picking up speed quite quickly. The mixed fluids smeared on his cock acted like a good-enough lubricant, easing him into her; any discomfort Yu felt turning into carnal pleasure.

And soon his thrusts hastened, his pelvis slapping against her shapely ass as he buried himself balls-deep in her asshole. Yu hissed, pushing back against him and getting his dick in her sooner than anticipation, forcing tight moans and low hisses out of the pair of them, both stubbornly refusing to admit how good it felt doing it anal. Though whilst they refused to admit it their bodies didn't lie; pleasure sparking across their nerves and encouraging them to keep moving, to keep fucking like animals in heat.

''Mn, b-bastard...'' Ritsuka hissed under her breath, glaring back at him from over her shoulder. ''Give me some warning next time.''

''Yeah, sure...'' Ritsuka breathed back, clearly intending not to.

Yu opened her mouth, but anything the Assassin wanted to say was lost amidst the resounding smack as his hand came down onto her ass, spanking her. Groaning Yu just pushed her ass back against him, her body jolting forth momentarily when he thrust back; a sharper hiss of bliss escaping her when he snaked a hand up her front, grabbing ahold of her hanging breast and fondling it mid-fuck.

Only to then drop his hand down between her legs, mercilessly shoving three fingers into her sex. Yu buckled, a sharp moan tumbling out of her throat before she consciously quietened it, her throat closing up and withering the sound into a lower, more rasping groan. Ritsuka smirked tightly at that, burying his cock into her tight ass and fingering her at the same time, her creampied walls stirred up by his thrusting fingers.

''Fuck, hah...!'' Yu tightened and tensed, her breathing raspy. ''H-Harder...!''

With a groan Ritsuka agreed, his pace increasing – as did the sound of smacking flesh. With one hand on her hip he helped yank her back towards him, their bodies sweaty under the warm spray of the shower as he fucked her ass, his hand sometimes darting up to grope her plump boobs before returning to her waist, his other hand busy finger-fucking the panting and gasping Assassin, the quiver to her legs betraying her nearing end.

Yet she didn't admit it. Gasping, hands sliding down the wet tiles and fingers curling into fists, she refused to concede – taking the ass pounding with gritted teeth and laboured breaths. Ritsuka held out for as long as he could, ramming the Assassin from behind relentlessly, not a second of pause even as curling licks of heat shot up his cock, the tightness of her ass too pleasurable to resist.

And soon Yu peaked. ''Mn!''

Wet honey gushed around his thrusting fingers, a thumb to her clit making her cry out at last – her asshole becoming ungodly tight around his shaft. Ritsuka barked out a curse and slammed into her, a shudder lancing through his body before he unloaded his seed into her ass. He couldn't even thrust further; simply pressing himself against her rear and riding out his climax.

''Mn...'' Until with a low groan he pulled out, his cock escaping her tight ass. ''Ah... hah...''

Yu was similarly out of breath; laboured, panting breaths punctuating the quiet. The spray of the shower fell over them constantly, heating their bodies up further until Ritsuka reached over and dialled it down to a more lukewarm temperature, cooling them a little.

''Well...'' Yu turned and put her back to the wall. ''That's enough de-stressing for one day, wouldn't you agree... Master?''

''Yeah.'' With much less roughness Ritsuka agreed, making room for her to join him in the spray. ''Your shampoo and stuff is still here if you wanna use that.''

''Sure.''

Then with remarkable casualness despite the rough sex that had happened, both showered up and soon parted ways – their bout of de-stressing told to nobody.
