A/N: First time writing Atsuko, so not too sure if I got her persona right here, but one can only try~

I do hope you enjoy~

Flower Bride

It was Valentines in Kivotos.

Coming around once a year in February it was a day to celebrate love, romance and all things related to it. Couples went about to theme parks and restaurants, friends hung out and snacked on the plentiful supply of chocolates on sale, and the whole place was dressed up in romantic pinks and reds; banners draped over streets and stores supplying specialised, thematic gifts or sweets.

Sensei hadn't had the pleasure of experiencing it before, but even just standing out on a street-corner watching couples pass him by, he couldn't help but smile fondly. The atmosphere was a cosy one, and not even the usual thugs were immune from it – he'd even seen a couple such thugs on dates themselves, often wearing much cuter clothing and acting much more demure with their dates. Amusingly, they still wore their face-masks.

Dispelling the memory with a slow shake of his head Sensei swept his gaze around the busy city street, looking about for a certain someone – and a second later spotted her bobbing through the crowd, her white hood enabling her to blend in well, but her lavender hair unfortunately made her stand out quite a bit. At least to his eyes.

''Hm? Ah, there you are, Sensei.'' Atsuko noted as she got within speaking distance, looking up at him with a curious expression. ''You wanted to see me?''

Sensei smiled and greeted her in turn. It had been some time since the whole incident at Trinity and since then he'd been spending a lot of time with the four former students of Arius. Saori had arguably been the easiest to work with; she was stern and a bit dense, but she had a good heart and her denseness actually came in handy more often than not, allowing her to work odd jobs without thinking about it twice, sans the time she had to wear a girly apron and promote a store. He took a picture to immortalise her flustered blush, sharing it with the other three gladly.

Hiyori had been a bit trickier, due to her chronic state of anxiety, but once she got used to him she was mostly fine, albeit with the tendency to run off in the wrong direction. Out of all of them though Misaki was the hardest to get through – she defaulted to closing herself off when she didn't know how to deal with something, and was aloof pretty much every other time, so conversation between them was short and often stiff. Nevertheless she'd defrosted somewhat over the preceding weeks, willing to stand and chat with him over meaningless things like TV shows and all that.

Atsuko though was different. She had a cute charm that wormed its way into his heart from the day they met, and the feelings of affection he held for her only got stronger since then. It took a conscious effort to make sure they didn't shine through, that he didn't show too much favouritism, but it got harder as time went on. Atsuko was just so pure, so charming, that she really did deserve the nickname of 'Hime'.

Chasing away such thoughts Sensei smiled down at his favourite student. ''Mm. I hope you weren't busy or anything.''

''Not really. Saori has work today due to the rush and Misaki is staying inside, so Hiyori is too.'' Atsuko noted lightly.

He hummed, privately relieved he wasn't ruining any plans she had. ''I see. Well, I remembered that I never got to show you around Kivotos, so I thought that today would be a good day for it?''

Atsuko blinked, slightly surprised... before a little smile curled at her lips. ''Are you asking me on a date Sensei?''

''A-Ah, nothing like that, I was just thinking, y'know...''

''Mmhm.'' Atsuko mercifully nodded, mirth twinkling in her eyes. ''I get it.''

Wordlessly she offered her hand, and with a sheepish smile of his own Sensei took it – leading her down the street, and onto their quasi-date.

X-x-X

Atsuko was a quiet girl, but a good one.

And also a curious one.

Thus Sensei saw it fit to whisk her around to a range of places, both fitting for the day and also less so. From popping into an arcade to having lunch at a fast-food place, to going to a petting zoo and then their current location – the botanical gardens located not far from Schale itself.

''So how's Misaki doing?''

''Mm. Good.'' Atsuko hummed, walking by his side and staring at a row of purple flowers off to their right.

Sensei smiled and nodded, content with the knowledge. Around them a few other people walked about but it was mostly staff members – the gardens were, surprisingly, quite empty. Maybe it was because there was no eating allowed indoors so most couples gravitated towards the parks for a romantic picnic, but the botanical gardens were serenely quiet, made only more so by how large they were.

The main building itself was a large dome with two branching arms to either side, gradually forming a wide circle around the gardens themselves that were easily the size of a park. However unlike a park the interior of the circle wasn't an open plain of grass with the occasional tree, but a menagerie of plants, flowers and trees all artistically laid out with winding cobblestone paths leading between them, the occasional bench the only seating available and encouraging visitors to keep moving; to see all of the gardens before they left.

And while Atsuko didn't jump for joy or smile broadly, the gentle gleam in her eyes, the upwards quirk of her lips, all of it spoke volumes to how much she liked being in such a place. Every so often they slowed their walk so she could inspect a flower or two; lifting the head up gently and admiring the pretty colours in its interior before moving on. He didn't rush her, following her more than anything and just letting her take things at her own pace. The lack of chatter might be uncomfortable to some, he knew, but Atsuko was never the most talkative person so he didn't take it personally.

As if jinxed by his thoughts, Atsuko spoke up. ''Sensei... do you want to take a seat for a bit? You look a little tired.''

Admittedly walking around Kivotos to various places did that to people, but he just smiled and waved her off. Atsuko however hummed under her breath and took his wrist in one hand and pulled him bodily over to the nearest bench – and by the time they reached it he succumbed to her whims and sat down, smiling wryly as she sat down next to him.

''You didn't have to.'' He murmured to her.

''Sensei needs a rest, so it's alright.'' Atsuko said simply as she sat next to him... before falling onto her side and laying her head on his lap. ''Pet me if it makes you feel better.''

With a sigh and a smile he complied, petting Atsuko's head and brushing his fingers through her hair, enjoying his short rest..

X-x-X

Eventually day turned to evening, and it was time to head back to Schale.

By the time they actually arrived at the giant building it was already nightfall, and as such Sensei invited Atsuko to stay overnight given it was dark out – while he was confident Atsuko could handle herself just fine against most opponents, that didn't change the fact he wanted to keep her away from danger. Atsuko gladly took him up on that offer, hand-in-hand with him as he led her into the elevator and took them to the uppermost floors, safe and sound from both attacks, and prying eyes.

With a ding the elevator doors slid open and Sensei walked out, leading Atsuko down the desolate hallways of Schale's residential wing. His own room was at the far end, the biggest on the floor, with mirrored rows of doors flanking the walls leading to it, able to house about thirty or so students max; more if they shared rooms. Naturally, he chose the door nearest his own to house Atsuko for the night.

'Or you could invite her into your bed...' A little whisper tickled his mind.

Sensei shook his head to rid himself of the tempting thought. Atsuko looked up at him with a raised brow but he just smiled, quelling whatever curiosities the lavender-haired girl had as they continued to walk in comfortable silence, making their way down to the door in question. A swipe of his card was all it took to open it and he led her in, their eyes adapted enough to the darkness to easily make out the modernist interior; a comfy double bed, basic furniture and window, of which the moonlight was currently pouring in through.

''Here you are.'' Sensei remarked warmly, letting go of her hand. ''The mini-fridge should be stocked with drinks and the little cupboard next to it has some snacks in it; should keep you going until morning.''

''Mm. Thank you, Sensei.'' Atsuko smiled warmly up at him, her red eyes seeming to twinkle with something else. ''Before you go, could we do the snoot challenge?''

Sensei blinked, surprised, before vaguely recalling the aforementioned 'challenge' from a video Aris showed him – involving making a circle with one's fingers and prompting their partner to stick their face in it like a cat. He'd never done it before, and the request came out of left field, but it spoke to how used to surprises he'd become that he didn't think twice before murmuring an agreement, raising both hands and forming a circle.

Atsuko smiled, her red eyes rich with amusement as she leaned in, grasped his wrists-

-and then pulled them down and kissed him.

His brain simply didn't function for a moment. Only after several seconds did he register that Atsuko was kissing him, his heart leaping up into his throat... before with a silent gulp he reciprocated. Her lips felt so small but so very soft against his own, only tempting him deeper into the kiss, every second seeming to drag on into an eternity as they just shared a moment. Eventually the need to breathe forced them apart but Sensei didn't pull away too far, just enough to refill his lungs.

And then he closed the distance of his own volition, kissing Atsuko. The lavender-haired girl smiled into it and she unhanded his wrists to cup his cheeks instead, letting out a happy hum as she kissed him back, their lips mashing together tenderly but with a hint of something more passionate. He shuddered at the thought and laid his hands upon her shoulders, keeping the kiss going for a little bit longer.

Eventually they drew apart for real, their lips a mere inch or two apart as they panted, collecting themselves. Sensei wanted to speak but couldn't find the words; losing himself in Atsuko's eyes and just wanting to do all sorts of things to her in that moment – he wanted to hold her, hug her, kiss her, strip her naked and make love to her until the sun came up – but his thoughts were put on-hold as Atsuko caressed his cheek, her dainty touch truly earning her the nickname of 'Hime'.

''Sensei.'' Atsuko breathed out, her other hand taking his right and guiding it to her cheek, allowing her to nuzzle it. ''Stay with me tonight.''

It wasn't a confession outright, but the gentle tone and warm eyes conveyed her true feelings well enough, easily making his heart skip a beat. Faced with such a sight he could only murmur an agreement and lean back in, reclaiming Atsuko's lips in a deep, passionate kiss, muffling the cute hum that arose from her throat. One that turned a pitch deeper as he grabbed her ass and picked her up, carrying her the short few steps over to the bed.

The kiss was broken off as he eased her down, his cheeks red and her own turning pink as she laid back onto the simplistic grey quilt. He left her laying there for no more than a second before daringly getting on top of her, balancing himself with one hand whilst his other slipped down, right palm pressing flush against her left and his fingers interlocking between hers, holding her hand.

''Tell me if I'm going too far.'' Sensei whispered. ''I don't want to hurt you.''

''...hehe.'' Atsuko tittered softly, eyes becoming half-lidded. ''Silly Sensei, I know you won't~''

Another shudder roiled through him, his mind almost fogging up like her words were putting him under a spell. He pushed back against the enthralling fog though and instead kissed the dainty princess under him, the gentle smacking of their lips ringing out in the quiet even as he slowly began to work on her white jacket, removing it little by little until Atsuko could simply roll her shoulders and slip out of it. Once it was out of the way he worked on her white dress next, hauling it over her head after removing her plate carrier and pouches.

Under it she wore a tight-fitting leotard, the material hugging her slender figure very nicely. Everything from her narrow hips up to her slim sides and medium-sized bust was emphasised by the material. It also carried up to her shoulders and along her arms, preventing him from simply pulling it down, but he didn't need to – something he proved as he instead slipped his hands around the open sides, groping her breasts.

''Mn...'' Atsuko shivered under him, but her smile didn't wane one bit. ''Do you like them, Sensei?''

''Mm.'' Tugging her leotard aside slightly he leaned down and kissed the top of her right breast. ''They're beautiful, just like the rest of you Atsuko.''

''Heehee, I'm glad~''

Smiling wryly Sensei peppered her smallish breast with an array of kisses both light and firm, soon working his way down to her nipple – pink and perky as he expected. His lips pursed around it and he gave it a tender suck, instantly earning a moan from Atsuko herself; one that gently spiked in volume as he flicked it about with his tongue, teasing more adorable sounds from her lips.

Swapping over he gave her other breast the same treatment, gently groping her tits as he did so and earning a small, dreamy smile from Atsuko that just encouraged him to keep going; his tongue working its magic dutifully and coaxing out all manner of lewd noises from the lavender-haired girl. However soon he craved more than just teasing her breasts, tempting him down between her legs, a simple tuck of her leotard all it took to get it out of the way, her simple black panties lasting only a second longer before finally revealing her pussy; smooth with a small tuft of lavender above her sex.

''Ah, Sensei... you're starin- mn!''

A cute moan wriggled its way out of Atsuko as Sensei's tongue flicked along her slit, the lick ticklish and quick but no less enthusiastic than those that followed. He held onto her thighs and kept them open, his eyes closing as he just focused on eating his student out, his licks leaving her slit wet with spit. He didn't content himself with just that though, his head tilting slightly as he went further up and attended to her clit, coaxing the little nub out of its hood and finally making Atsuko moan in utter delight.

The sound fuelled the excitement pulsing through Sensei and he upped the ante; his tongue going back down and licking at her entrance, his tongue slithering this way and that in a constant, tumbling motion, his right thumb soon coming up to rub at her clit too and making Atsuko flinch with pleasure, her moan soft and laboured.

''Ah, haah... it feels so strange...''

Sensei flicked her clit with his tongue before leaning back, rubbing her slit with his fingers as he spoke. ''In a good or bad way?''

''Good.'' A smile curled at her lips, warm and a touch mirthful; the corners of her mouth curving up. ''Very, very good.''

The way she managed to come off as simultaneously seductive yet innocent really got him going, his pants tight, but he resisted the urge to take her right then and there. Instead Sensei gently parted her folds and went down on her once more, his tongue in constant motion and eliciting a constant stream of gasps and whimpers from Atsuko, her face scrunching up from the pleasure she felt and her gloved hands coming to rest upon his head, gently pushing him into her crotch.

He was all too happy to continue servicing her; his licks switching between shorter, faster flicks or longer, deeper strokes, never giving Atsuko time to adjust to the sensations and sometimes going higher to kiss and suck on her clit. He felt her slender thighs tense and jerk as pleasure shot through her and her whines became increasingly breathless, her perky chest heaving with every quick breath she drew in, her light blush long since replaced by a rosy one.

Spicing up his tongue motions he threw his fingers into the mix; inserting two fingers inside of Atsuko and pumping them in or twisting them about within her, the slightest scissoring motion instantly making her loins clamp around his digits, the moist heat of her insides tempting him to curl his fingers and tease out a trembling moan from his lover, his tongue dragging itself over her clit at the same time; making her spasm and writhe with pleasure.

''Mn! S-Sensei, I'm- ah~!''

A girlish cry escaped Atsuko as she finally orgasmed, pulling him into her crotch even as he tongued her clit, making her squirt from the force of her climax. Sensei kept jamming his fingers inside of her as she came, relentlessly working his wrist and making Atsuko spasm under him, every jolt of her slender body intimately felt and tempting him to push his face into her groin, kissing it heatedly and making her moan tightly.

Gradually he slowed his fingers down, gently letting her down from her high before eventually Atsuko eased back down against the bed, panting heavily from the force of her orgasm. Only then did Sensei pull away from her crotch and sat back, wiping his chin dry with one hand and just admiring her flushed face and soaked sex, his pants feeling decidedly tight at that moment – his formal pants straining against his erect cock.

Something that Atsuko noticed, her cheeks darkening but a lazy smile crossing her lips. ''Sensei... you can put it inside me, you know.''

''Ah... are you sure you wanna go that far...?''

Atsuko simply bobbed her head, not bothering to vocalise her want – doing so by opening her legs wide, inviting him between them. When faced with such a sight Sensei couldn't hope to resist, quickly undoing his pants and kicking them off alongside his shoes, his boxers the last to go and leaving his lower half bare. Atsuko blushed at the sight of his dick but didn't stop him as he got on top of her, his shaft pushing against her loins and making her quiver with anticipation.

''You ready?'' Sensei asked caringly, rubbing his cock up against her folds.

Atsuko let out a staggered breath and nodded, holding her right hand out. With a smile Sensei laid his left palm against her right and held her hand once more, squeezing it reassuringly even as his other hand guided him down, his cock-head sliding along her slit once, twice-

-and then on the third go he pushed inside, claiming her first time.

''Mn...!'' Atsuko winced slightly as it went in, drawing in a shuddering breath.

''You okay?'' Sensei inquired immediately, concerned.

''...yes, it just stings a little.'' A small smile twitched across her lips and she squeezed his hand tighter. ''The pain... just means Sensei and I are really one, heehee~''

Sensei blushed at her playful remark and responded by leaning down, claiming her lips in a kiss. Atsuko hummed happily into it and clutched onto his shoulders, drawing the kiss out for a few more seconds before both finally pulling back – only then nodding her head, telling him to go ahead. Something that Sensei complied with immediately, rearing his hips back and pulling out to the tip before burying himself back inside of Atsuko, parting her tight vaginal walls inch by inch with his dick.

Though Atsuko was a very tight fit the foreplay helped ease him into her; every roll of his hips inching him in deeper and deeper until the tip was kissing her innermost parts, eliciting a cute moan from his lover. Propping himself up on both hands Sensei peered d own at the leotard-wearing student, holding her aroused gaze as he pumped between her petals, her pussy gripping him ever so tightly yet causing no discomfort, only pleasure.

Puffing out laboured breaths Sensei kept moving his hips, the mattress giving a quiet squeak of protest yet not a single one came from Atsuko's lips, her entrancing red eyes half-lidded as she kept staring at him, as if not wanting to miss a single moment. Responding to her unspoken want he leaned down and kissed her once more, squeezing her hand one more time before releasing it and groping her breast instead, his thumb flicking her nipple repeatedly until she moaned.

''Hn... Sensei, you can... ah, go faster...''

''You sure...?''

Atsuko just levelled him with an amused look, as if he'd said something silly. Blushing with embarrassment he uttered a quiet apology before kissing her once more; dragging it out as he continued pumping himself into her slick, gripping depths, her walls clinging to his cock every time he pulled back and just encouraging him to slam back in with more force, fucking moans and sighs of satisfaction from her lips.

Growing more confident when she showed no signs of pain Sensei leaned back, his hands sliding up her thighs until he grasped her knees; holding onto them as he pumped himself inside of her more roughly, stuffing himself up to the hilt in her narrow pussy and fucking cries of pleasure from Atsuko's lips, her pitch rising and falling with every thrust and her expression twisting too; lips pursing, brows knitting, her whole face scrunching up before she relaxed with a breathy moan.

''S-Sensei...'' Atsuko called his name, her thighs brushing against his hips before slowly wrapping around it, her shoes bumping together behind his back. ''Finish inside of me...''

A shudder travelled through him, her mere request a sin, but one ever so tempting. ''I'm not wearing any protection Atsu-''

''Good.'' Her ankles interlocked behind him. ''My wish, is for Sensei... mn, to become... my prince, and mine alone...''

The words reached his mind, and any fear of consequences evaporated. With a tight, lustful groan Sensei lifted Atsuko's thighs and folded them over herself, mating-pressing her into the bed right before he started to pound her with renewed conviction – flesh loudly smacking against flesh as he went balls-deep in her over and over again. The position knocked gasps of pure bliss from her lips, her eyes widening and her lips parting as her voice filled the air around him, each sharp gasp or budding cry sweet on the ears.

The bed continued its protests, squeaking and rocking under them, but with nobody around to overhear he had no fears about going balls-deep in his student, in Atsuko. His cock-head reached her innermost parts and banged on the gates of her womb whilst his weight pressed down upon her folded thighs, squishing her down into the bed and leaving the leotard-wearing girl struggling to breathe, yet so totally stuffed she could hardly find it in her to care.

''Ah! Ah! S-Sen- sei!'' Atsuko cried out to him, her loins coiling tightly around him, squeezing him, begging him to empty himself within her-

-and with a shout, Sensei gave it – sheathing himself up to the hilt inside of Atsuko and unloading a thick torrent of cum that splashed across her inner walls and utterly flooded her womb. Her own orgasm struck nary a second later, her walls seizing tight around him as she thrashed under him; gasping in wordless, unrivalled bliss. He managed to keep moving, somehow, and slammed his cock down into her with a vigour befitting a man possessed, the uneven smacks of skin echoing out.

Until with one final thrust he slammed inside Atsuko and went still, groaning deeply – a finality to the sound. Pleasure twitched along his swollen cock, a few beads of semen dripping into her and adding to the thick amount he'd shot inside of her. With her ass raised up though none seemed able to leak out so he kept her there; pulling out but keeping her mating-pressed into the sheets.

''Atsuko...'' Sensei panted out, staring down into her half-lidded red eyes.

Red eyes that warmed with a gentle, unadulterated affection, ''...call me that more, Sensei...''

''Atsuko.'' Sensei murmured her name again, letting her legs fall limp only to bury his face into her neck, kissing just under her ear and earning a little moan from her. ''Atsuko, Atsuko...''

Every utterance of her name only turned the lavender-haired girl on more, a cutesy whimper escaping her lips as she ran her hands over him, pawing at him with no direction or real intent, just senselessly want. He replied in kind, kissing along her jawline until he met her lips in a deep, passionate sort of lip-lock, the two of them smacking lips for a few moments before he went down and attacked her right breast, kissing and nipping gently at the flesh, knowing a hickey or two might form. He wondered what Saori and the others would think if they saw it.

He pushed such thoughts of her friends from his mind though, kissing further down to her stomach – before a hand in his hair pulled him back up, their lips mashing together. Sensei groaned and pushed himself against Atsuko, almost spooning her as he humped her ass and coaxed her onto her front, his weight pressing down upon her. That was until she raised her ass up, pushing it against his cock and almost grinding herself back against him, tempting him to pull back long enough to guide his cock into her wet, dripping hole-

''Ah...!''

-and then he was back in her snug pussy.

''Sensei~'' Atsuko almost whined his name – her tone taking on a slightly shy, yet undeniably aroused note.

One that Sensei found himself loving, pushing his face into her hair and inhaling her scent, a faint flowery perfume that mixed with her natural smell. He brushed her hair aside with his nose and kissed at her nape, teasing her smooth flesh even as he started to thrust into her once more – slow but strong roll of his hips burying his meat inside of her, her loins squeezing him tightly in return as if to encourage him, some of his cum load scraped out by his thrusts, but he knew most of his seed would stay within her cradle. Whether he'd knocked her up or not, he didn't know, but by the end of the night he was going to make sure she was.

Capitalising on that lustful though Sensei pressing himself against Atsuko more, almost spooning her as he did her doggystyle – his thrusts quickening and becoming shorter, clapping her perky ass at a steady pace and coaxing out a stream of moans from his lover, her arms quaking briefly before she reaffirmed her grip. In response Sensei reached around and laid his hands over hers, his fingers slipping between hers too and just pinning them to the bed, keeping her on all fours as he mated with her like a dog.

''A-Ahh... I like this, Sensei...'' Atsuko breathed out, a moan carrying itself out past her lips. ''I can feel your warmth behind me, and inside me... teehee~''

The playful words only aroused Sensei more; a low, eager growl escaping him right before he pounded Atsuko with renewed effort, burying his cock between her slippery walls and bumping on her innermost parts like a battering ram, every impact jolting her petite form forth before Atsuko pushed herself back onto his cock, moaning happily as she felt his cock-head nuzzle her innermost parts. The cum inside her sloshed about from his constant thrusting too, some of it spilling out but much remaining inside her womanhood, making her pussy feel delightfully sloppy.

Every impact against her ass made it ripple nicely too, the position allowing him to admire her cute behind and smooth back, his lips soon coming down and attacking her nape once more – a slew of kisses peppering her flesh and soon joined by multiple quick hickeys, coaxing out even more adorable moans from his lover. Arching her back slightly Atsuko pressed her lips against his in an over-the-shoulder kiss, the position made a bit awkward with him holding her hands down, but they managed and just shared a quick moment.

Then their lips broke apart and he went back to railing her like there was no tomorrow. Atsuko let out a gasping cry and bowed her head, only serving to expose more of her neck that he could kiss, his breath washing over it with every exhale and his lips peppering her flawless flesh, marking it with rougher kisses, marking her.

''Sen... S-Sensei...!'' Atsuko cried out, her fingers digging into the bed. ''I-I feel... strange, a-agai- ahn~!''

A sharp, choked cry, a seizing tightness – and with a low groan of his own Sensei sheathed himself balls-deep in her and busted another load between her clenching walls. Relief washed over him in waves and his muscles tensed and relaxed at just the right intervals, pleasure shooting down his cock as he just poured all of his seed inside Atsuko, her womb a cradle for the baby he was putting inside of her.

Releasing a shuddering breath Sensei rolled his hips a few more times, feeling her loins squeeze his cock lovingly before finally he pulled out, exhaling a heavy breath. Weakness twitched at his thighs and he eased himself down onto the bed next to Atsuko, one arm wrapping around the lavender-haired girl and pulling her into his chest, her own arms wrapping around his chest and her cheek pressing against his pectorals.

For a long moment, they laid there just panting.

Then Atsuko gently broke the quiet. ''Your heartbeat... I can hear it.''

''Do you like the sound of it?''

''Mm. It's comforting.'' Atsuko emphasised that as she rubbed her cheek into his torso, inhaling his scent. ''Sensei... I love you...''

''I love you too-'' He kissed her forehead. ''-Atsuko''

At that, Atsuko only smiled and cuddled herself into him, the two laying there until eventually falling asleep, waking up the following day in one another's arms.
