A/N: Rare Mash story~ Felt fitting for winter considering the pic that inspired it~

Do enjoy~

Snow Plum

Ritsuka got a holiday.

A rare thing, considering how many disasters and world-ending events seemed to happen at Chaldea, though perhaps that was just because they were tasked with handling such problems that it seemed common. Nevertheless Leonardo had seen it fit to grant him a few days away from the place to cool off and rejuvenate himself. As such, he'd opted to take a small holiday to the Alps, whisking Mash along with him for company.

Leonardo handled all the financial stuff so they had nothing to worry about, simply taking a plane and travelling over to France with nary a delay in sight – though whether that was good luck or Leonardo's hand, he neither knew nor really minded. All that mattered was that the two of them soon arrived at their lodge for the next few days, the wooden structure isolated from any other buildings by a good distance but still within reception range in case they needed help.

And after settling in and exploring their home, they decided to make use of one of its amenities; the outdoor onsen.

''Ah, is this the room?''

Mash's comment flowed lightly through the crisp air as Ritsuka pushed the wooden door open, his gaze wandering over the interior. It was small, almost cramped in a way, but that was to be expected for a changing room meant for just one or two people. The smooth chocolate-hued walls flowed up into an arched roof, a light dangling from above and with little in the way to spruce up the room; just a row of hooks for coats and such with a bench underneath, matching the same on the other side.

''I would've thought that they'd be divided...'' Ritsuka murmured, some warmth colouring his cheeks. ''You go ahead Mash, I'll wait outside until you're done.''

''Y-You don't have to, senpai...'' Mash said embarrassedly. ''We could just turn our backs and not look? That would be fine, right?''

Ritsuka paused to consider that, some warmth colouring his cheeks just as it did Mash's – leaving him torn between denying and hurting her feelings or accepting and risking an embarrassing situation.

In the end he chose the latter. ''S-Sure. I guess that could work.''

Smiling demurely up at him Mash stepped past him into the room, her pace slow and a bit shuffling, but any embarrassment she felt was muted somewhat by her excitement to try out the onsen. He had to admit he felt the same; managing to swallow the bashfulness rising within him and stepping inside the cramped room, pulling the door shut.

Glancing briefly back at Mash to make sure she wasn't looking, Ritsuka began to strip. Slowly at first, fiddling with his jacket and tugging it off with more lethargy than he truly felt, but when he heard the sounds of Mash also getting undressed he picked up the pace a little. The black thermal top he wore came over his head easily and was shaken, folded and then set aside on the bench, his thick cargo pants soon coming down as well. Without his winter boots to get in the way they came off easily, ending around his ankles and allowing him to thumb the waistband of his boxers.

It was then he chanced a peek back at Mash.

It was worth it. Clad in just a pair of white panties and a bra she struck an inviting figure – especially as she bent over, emphasising her shapely ass that dug into her panties, a slight camel-toe visible from her position. He looked away before she could notice but her figure was burnt into his mind, from her taut back muscles to her thick thighs, every aspect of Mash leaving Ritsuka pursing his lips to contain the sudden arousal filling him.

Perhaps sharing a changing room wasn't the best of ideas.

Nonetheless both of them finished shortly, a faint hiss filling the room as Mash took her underwear off, the fabric sliding across her skin. He reached over to the left where the stack of towels were - and brushed hands with Mash as she did the same. He pulled his hand back as did she, his gaze reflexively darting her way.

Boobs. Large, plump and pushed up by the arm pressed against them, they looked divine.

''S-Senpai!''

''Sorry!'' Ritsuka looked away, but the image of her chest filled his mind. ''Didn't mean to look.''

''...you're forgiven, but please don't do that again, it's embarrassing.'' Mash said with a light sigh, picking up her own towel. ''You can take your towel now, senpai.''

''Right.'' Managing not to stutter Ritsuka plucked up one towel at random and all but threw it around his waist, tying it firmly at the hip. Last thing he wanted was for it to fall off.

Mash on the other hand tried to wrap it around her front, but due to the towel's size and her bust, couldn't. After a bit of audible fumbling she gave up with a sigh. ''Senpai, you go first.''

Wisely not questioning her Ritsuka bobbed her head, keeping his eyes mostly closed until he reached the door, allowing him to pull it open with a firm yank. Immediately cold air wafted inside, nipping his exposed chest – but any such discomfort was immediately blown away compared to the view presented before him.

The wooden balcony stretched out just a dozen feet, a wide but narrow rectangular onsen present – and beyond that laid a vast, snow-covered valley, the mountains on either side glittering as the evening sunlight spilt upon them. The amber rays were warm against his skin and the pinkening horizon added a soft sort of look to it, the sky gradually darkening as night neared. Countless trees were dotted about, the ones nearest to the lodge barren and with branches bearing snow, whilst along the mountainsides were lush pines that hinted at the greenery hidden beneath the blanket of glimmering white.

It was beautiful. Plain and simply, beautiful.

''Wow...'' Mash breathed from behind him.

Glancing behind himself Ritsuka noted she held her towel to her front, covering most of herself but leaving her legs and hips bare, a hint of some side-boob also present. However all those details were secondary to the wonder on her face; eyes wide, a slight, growing smile, the relaxed expression and the quiet contentment in her eyes... she looked even more stunning than she usually did.

Wordlessly Ritsuka offered her a hand, drawing Mash's gaze away from the horizon – and with a demure smile she accepted his hand, letting him lead her over to the onsen. Even in this cold weather the water still steamed from whatever was heating it, the air around it losing some of its nippiness. Sitting down on the edge Ritsuka dared to dip his toes in and found the temperature pleasantly warm, immediately enticing him to sink down into the warm onsen water, sighing in content.

Mash joined him a moment later, sighing in equal bliss. ''Ahh... finally.''

''Not like the cold?'' Ritsuka asked lightly, reclining against the wooden edge.

''I don't mind it, per se. If I'm active it's fine, just...'' Mash seemed to struggle for words.

''...just you don't like standing around in the cold?'' He finished for her.

''Yes, that's exactly it.'' She blushed lightly. ''And being... unclothed, outside is a bit embarrassing too.''

''I get what you mean.'' Ritsuka hummed.

The two of them lapsed into a comfortable silence, neither really in a rush to break it; they'd worked together for so long, been friends and partners for so long, that neither really needed to say a word to convey what they felt. And right now, cosying up in a warm onsen and overlooking a gorgeous view, the silence between them amply conveyed the quiet wonder that such a view gave them.

How much time passed like that neither were really sure, losing themselves in the moment, but as they listened to the gentle howl of the wind and occasional flutter of a bird, Ritsuka stole glances over at Mash. She looked stunning in the waning sunlight, and the way she gently kept the towel flush against her front only enhanced that beauty; his gaze unconsciously tracing all of her curves. He'd been doing that more lately, he knew, but it was an insatiable sort of action; never able to get enough of just looking at her, clothed or not.

Mash happened to glance his way then. Immediately both of them blushed a light pink and averted their eyes... only to glance at one another and repeat the process again a split-second later. After a second Mash responded by rising to her feet and sitting down on the edge of the rectangular onsen, either not noticing or not minding the way Ritsuka looked at her thigh. The young man in question soon joined her, water sloshing as he sat up beside her, the two of them looking over the valley.

''...senpai...'' Mash's hand slid over his own, her fingertips curling under his. ''Thank you for bringing me.''

''Of course.'' Ritsuka answered with equal softness. ''It's nice to see the world when it's not on fire, isn't it?''

Mash smiled faintly. ''Mm, it is. It makes me want to protect it even more, to make sure everyone else can enjoy a view like this. Do you... do you think that's possible?''

''With you by my side? Guaranteed.'' Ritsuka said warmly.

Mash smiled adorably at that, a light flush to her cheeks that only accentuated how inviting her pink eyes were in that moment. His heart thumped loudly in his chest and for a moment Ritsuka wasn't sure what he was doing, his hands reaching out to her subtly as if to hold her... before he let instinct take control and went with the flow, snaking one arm around her lower back and cupping her cheek.

The sudden closeness made Mash blush, her cheek hot against his palm, but Ritsuka couldn't tear his gaze away from her alluring pink eyes... and without stopping to think, he leaned in and kissed her. It felt like time stopped for a brief instant, his lips pressing against her own – and then time resumed as Mash tentatively pushed back, reciprocating the kiss. It lasted just a few seconds but by the time both drew apart their eyes were locked onto one another, too enraptured by the other to look away.

''Senpai...'' Mash breathed, leaning in.

Ritsuka met her halfway, lips mashing against her own and making Mash mewl softly. His hand slid from her cheek down to her side, touching wet flesh but not going further than her underarm, but the way his palm inched towards her chest made his want apparent. Wordlessly she let her towel go, the soaked-through material bundling over her thighs and leaving her plump, full breasts bare to him, immediately tempting Ritsuka to lean back just so he could get an eyeful of them.

Mash blushed, about to cover her breasts with an arm but pausing mid-motion – demurely setting her arm back down, letting him look. Ritsuka savoured the adorable motion and responded by reclaiming her lips in another kiss; both of his hands coming up to grope at her large tits, squishing them between his fingers and groping a moan from his partner; their lips drawing apart for a brief moment before reconnecting in the next, their locked lips muffling their moans.

''Mmph...'' Mash didn't resist as he moved his hands onto her sides, gradually easing her onto her back, leaving him atop her. ''Ah... senpai...''

Ritsuka shuddered at the way she breathed the honorific out; how she looked at him from under her fringe with open affection, open love. Unable to resist her adorable charm he dove back down and kissed her passionately, devouring the surprised mewl that arose within her throat, her hands pawing over his chest and sliding down until she reached his towel, her slender digits hesitating. Ritsuka helped her along, guiding her hand into his towel and tugging her wrist, pulling it with her until it loosened and fell to the floor.

The air was cold, frigid even – but in that moment it barely mattered, the heat of their bodies keeping it at bay for the moment; aided by the warm onsen beside them. Pressing himself down against the naked Shielder Ritsuka deepened the kiss, intimately feeling her skin in contact with his own – her thighs rubbing his hips and his groin flush against hers. Undoubtedly Mash felt his erection pressing against her but she didn't pull away; if anything she seemed to like the sensation, a happy moan escaping the Servant as she kissed back.

''Mmph... senpai...'' Mash mewled into the kiss, pulling back with a slight, breathless smile. ''Don't stop...''

In response Ritsuka immediately reconnected his lips with hers, devouring her moan and dragging the kiss out – only to break it off and go lower, taking her right nipple into his mouth. The Shielder moaned in surprise, her back arching as he suckled on her tit – her voice freely spilling the air when she had no fear of being overheard, isolated from civilisation as they were. Ritsuka felt the same, one arm sliding under her back and his hips starting to rock, grinding himself against her.

Popping his lips off of her nipple he swapped over to her other breast, peppering her creamy flesh with kisses and leaving Mash moaning in bliss, her hands blindly running over his back and her nails gently scraping his flesh – not enough to hurt or even leave marks, but enough to be felt, to let her ground herself on something. Those same nails dug into his shoulders as he shifted further down, his kisses tickling her stomach and then her groin.

And then Ritsuka buried his face into her crotch, dragging his tongue up her slit. Mash cried out, voice sweet and shaky as she felt his tongue flick again; moving in quick, eager strokes, making up for a lack of experience with earnest desire. His hands ran along her creamy thighs and groped as he went, committing every curve, every inch of detail of memory. His tongue worked furiously, stroking up her slit or teasing her folds.

''M-Mn~'' Mewling in response Mash ran her fingers through his hair, pushing him down into her crotch. ''S-Senpai~''

Just hearing Mash call him in such a manner made Ritsuka's cheeks burn, carnal desire flaring hotly in his chest as he continued eating her out – letting instinct guide him. He pulled his tongue away from her pussy briefly and replaced it with his fingers instead, sinking two digits inside of her and thrusting them in, allowing him to kiss at her inner-thighs instead – eliciting all manner of moans from the Servant, her head tossing from one side to the other as his fingers explored her sex, twisting and scissoring apart.

Kissing his way along her groin Ritsuka met Mash's half-lidded eyes, both of them blushing at one another... before with a whimper Mash covered her face with an arm, too embarrassed to continue the stare-off. Smiling sheepishly Ritsuka responded by scissoring his fingers apart inside her, immediately coaxing a moan out of his partner – one that spiked in pitch when he brought his tongue down upon her clit, licking the little nub and making her whole body spasm briefly.

Mash's moans filled the air as she tipped her head back; a strained, whimpering sound fleeing her lips as she breathed out his name. ''S-Senpai~''

Ritsuka raised his head at that, closing the distance between them in a second and mashing his mouth against hers, muffling Mash's moan as he pulled his fingers out. She threw her arms around him in an instant, hugging his body against hers, their skin flush together as if to stave off the chill with nothing but their body heat. Moments later they broke off the kiss with a mutual moan, their eyes drawn instinctively to one another's even as Ritsuka shifted into position, her legs laying on either side of him.

''Mash...'' Ritsuka swallowed. ''Can I...?''

''...mm.'' Mash smiled – a small, infinitely beautiful smile. ''Be gentle, senpai.''

Ritsuka blushed and murmured an agreement, grasping his cock and guiding himself to her entrance, the tip rubbing along her smooth nether lips and nearly dipping in once, twice – and then on the third go he pushed inside. Mash gasped, then whimpered; back taut as it arched and her fingers curling into fists, enduring the initial discomfort as he sunk inside of her. Ritsuka on the other hand held onto Mash tightly; groaning in total bliss as he felt her wet heat gradually engulf his erect shaft, the sensation unlike anything he'd felt up to that point.

Until soon most of his cock was buried inside of her. Hissing out a soft breath he pulled out until just the tip was inside before spearing back in Mash, feeling her slick insides part for his intruding length. He was careful not to be too rough but staying still bordered on impossible; her insides caressing his cock in such a way that it felt more natural to move, to glide between her wet walls. Mash moaned at the sensation, biting her bottom lip for a moment before lolling her head his way, holding his gaze as she slowly pistoned in-and-out of her tight tunnel.

''Senpai...'' Opening her arms Mash managed a smile for him. ''Kiss me...''

Ritsuka complied, leaning down on one elbow and kissing his newfound lover, both of them moaning into it as he continued thrusting into her. There was no rush, no haste, and with every roll of his hips any discomfort Mash felt melted away bit by bit, her hands sliding over his torso with growing confidence – touching and feeling him freely. Ritsuka responded by daringly picking up the pace, his slow thrusts quickening and fucking a gentle moan out of the Shielder, her insides clenching down on his cock tightly.

Breaking off the kiss Ritsuka groaned, his flesh smacking against Mash's own as he got more into it – everything beyond the two of them seeming to fade from his perception. He leaned down but instead of kissing her on the lips he dove down and attacked her neck, peppering her smooth skin with a slew of kisses. Mash squirmed under him, moans tumbling freely from her lips before they pursed, holding the flood back for only a mere second before more tumbled forth, as endless as they were erotic.

''Mn, Mash...'' Planting one last kiss on her neck Ritsuka grabbed her thighs and raised them. ''Sorry, I can't hold back, you're too cute like this.''

''Senpai don't say that, it's embarrass- mn~!'' Mash's embarrassed mewl escalated into a yelp as he folded her legs over herself, shifting more on top of her – and with renewed vigour Ritsuka started pistoning down into her tight tunnel, mating-pressing her into the wooden deck. ''Ah!''

The sound of slapping flesh echoed throughout the crisp winter air; each smack loud and resounding. His hands left her legs quickly and planted themselves on the warm deck, his hips in constant motion and driving his swollen shaft deep inside of Mash – knocking on her cervix as he went to town on her, railing her like he was a beast and she was his mate. A role that Mash succumbed to willingly, her shrill cries and throaty moans permeating the air.

Air that became short in supply as he kept up the rapid tempo; every guttural grunt and breathless groan leaving Ritsuka panting for air. However he refused to stop or slow, pleasure pulsating along his cock as he plunged between her clenching inner walls, the slippery, seizing grip feeling more and more intense by the moment. His orgasm began to near but he kept moving, ramming himself down into her clenching tunnel, her insides clamping down on his dick-

''S-Senpai~!''

-until with a cry Mash climaxed, her insides seizing around his cock. Suddenly holding back wasn't an option and Ritsuka bucked his hips back, gasping as he grabbed his cock and jerked off – and with a throaty moan he unloaded right up her stomach; thick white streaks painting themselves up her stomach and over her breasts, each rope hitting her skin with an audible splat. Mash quivered at the feeling, eyes half-lidded as she peered down at him, mewling as he shot another couple spurts onto her stomach and groin, leaving her entire front sticky with his load.

''Ah... senpai...'' She breathed.

Ritsuka just flashed her a breathless smile, getting one in return; both of them too busy panting to really form words. Ritsuka's gaze though descended back to the mess he'd made on her stomach, the mere sight – the mere reminder that he'd just fucked Mash getting his dick perked right back up in moments. The stiffness of his shaft didn't bypass Mash's notice either, the Shielder silently blushing as she noticed... before with a bitten lip she shuffled over to the onsen, sliding down into the water.

She rose back up after a second, the brief dunk in the water washing away most of his load – but what solidified his attention the most was how Mash stood up, baring her behind to him as she bent over the railing; overlooking the valley and presenting herself to him at the same time, water glistening across her fair skin. Hypnotised by the sight Ritsuka sunk back down into the water as well and shuffled behind her; just enough room present between them for him to move, his cock rubbing along her ass as he got into position.

Just before he stuck it inside, Mash spoke. ''Senpai... please, can you finish inside this time?''

Ritsuka paused. ''Is it safe...?''

''I'm not sure.'' Mash admitted, a bit meekly. ''But even if it's not... I don't mind if it's you, senpai.''

The honest affection she looked at him with instantly made the decision for him, and whilst he held her gaze Ritsuka speared back inside of her – stuffing Mash to the brim in a single, clean thrust. The Servant cried out in pleasure but Ritsuka was past the point of taking things slow; both hands settling on her hips as he pounded her raw. The water around their thighs sloshed from the force of his movements, his cock seamlessly sliding out to the tip and ramming back in until he practically kissed her cervix, stuffing her to the brim.

Mash told him how she felt about that; loud, blissful cries echoing through the air as he clapped her cheeks, her rear jiggling from the force of his quick thrusts. Ritsuka paid it little mind though and ran his hands up her front until he could grope her breasts, practically spooning her from behind as he felt her up mid-fuck, the overwhelming barrage of sensation rendering Mash little more than a moaning mess, her hair becoming dishevelled as their bodies jerked back-and-forth.

''Hah, a-ahh~! Mash threw her head back and moaned, glancing back at him from the corner of her eye. ''S-Sen- mmph~!''

A hand to her cheek pulled Mash right into a kiss, the surprise in her eyes fading in a heartbeat as she reciprocated, her lips mashing against his. Even as he kept pounding her from behind they dragged it out, their tongues soon getting involved and wrestling between their mouths, both equally inexperienced with it but tongue-wrestling as best they could; a feat in and of itself with how many moans bubbled up their throats, forcing them apart several times before mashing their lips back together.

Breaking off the kiss first Ritsuka groaned, leaning back upright a bit and peering past Mash's sweaty form at the valley, the picturesque scene only amplified when a naked Mash was bent over in front of him, love in her eyes as she peered back at him. Smiling tightly back at her Ritsuka unhanded her sizeable tits and laid his palms upon her shoulders instead, bracing her as he sped up; his thrusts becoming shorter but faster as he focused just on jamming his dick into her tight, velvety tunnel, moaning freely as pleasure seared his nerves.

''Mm! Hn! Ah- oh!''

The array of noises he fucked from Mash's lips were as exciting as they were erotic, the noise only fuelling his thrusts and making him hilt in her with every ounce of strength he had; confident Mash could handle it. She did and with ease; pushing herself back onto his dick with a needy whimper, her womanhood pressing down upon his length as if to massage the cum out of him, to get the creampie she asked for.

The mere thought only hastened his end. Of cumming inside of Mash. Of knocking her up. Of watching her stomach swell as the two of them prepared their own home for the baby. Of introducing his Servants to the baby. So many thoughts, equal parts lewd and wholesome, circled in Ritsuka's lust-addled mind and just added fuel to the fire, primal instinct egging his hips forth, his swollen shaft ramming deep inside Mash with the single-minded desire to knock her up.

And soon, he couldn't hold the urge back.

''Mash-!''

''Senp- iyee~!''

His cock hilted inside her just as he came – and Mash squealed as he emptied his balls inside her, unloading gushing ropes of cum that splattered across her inner walls and pumped deep into her womb. The tip of his cock pushed against her innermost parts, spurt after spurt of his warmth pouring inside her as he came harder than he ever had before, filling her willing womb until could take no more; all the excess semen leaking out around his erect shaft.

Gritting his teeth Ritsuka managed to rock his hips just a little longer before his stamina ran dry, and with a deep moan he pulled out; stumbling back a step and leaning against the edge of the onsen. Mash stayed where she was, clinging onto the railing for support and unintentionally presenting him with a nice view of her peachy ass; a thick dribble of cum spilling from her pussy as she stood, some of it seeping down her thigh.

''Mn... senpai...'' Her delicate voice drew his gaze to her face; one eye visible from beneath her hair. ''...I love you~''

Ritsuka blushed at the confession, but a light smile curled at his lips – the words coming to him easier than he expected. ''I love you too.''

The delighted giggle that escaped Mash was music to the ears.
