Work Text:
It was commonplace for Sensei to have an 'assistant' while he worked at Schale.
Officially, the position was one that gave good life experience to the students who helped them, teaching them how to work in an office environment, how to organise files and manage duties, all that – but unofficially it was a way for Sense to spend some time with the various students under his umbrella, getting to know them better and helping work through their problems in a safe environment, away from their peers or tutors. It worked well, from helping Yuuka de-stress or helping Momoi focus on something other than video games.
Mari was no stranger to the job. Originally assigned as per the usual rotation, she often came in voluntarily in the months following, working by his side diligently. She had somehow gotten it into her head that the best way to make him happy – and herself happy, by extension – was to make his life as easy as possible, namely by helping him with work. He couldn't deny that it worked; though she wasn't as work-efficient as Yuuka or as wise as Hina, she had an sunny earnestness to her that helped keep his fatigue at bay.
''Sensei, here's the files you wanted.''
''Mm. Thanks Mari.''
''Hehe~''
Mari's bright, adoring smile brought warmth to his heart and coaxed light chuckle out of Sensei's lips, his gaze falling down to the documents she'd handed over. Just some files on misbehaving students that he had to look over, given to him to decide their punishments since they'd graffitied the side of the Schale building. Nothing too bad, but he had to set an example with them lest others be enticed to do it. Schools were one thing, but doing it to a central authority like Schale risked setting bad precedent.
Humming he read through the documents and slowly rose to his feet, pausing long enough to take a sip of his coffee before making his way across his spacious office, heading for the filing cabinets over to be the corner. A potted plant rested on top of them, a painting hung by the wall, he even had a little charm dangling lightly from one of the cabinet handles courtesy of Chinatsu. Little bits of colour that brought a lot of life to the office.
''Um, Sensei...'' Mari suddenly spoke up, a bit shy all of a sudden.
''Hm? What is it?'' He inquired without looking up from his work, idly tugging on one of the drawers.
''Erm, well, I wanted to... no, I need to tell you something.'' Mari inhaled a quick, fortifying breath... before whimpering and squirming in place. ''A-Actually I'll tell you later, I don't want to distract you during your work!''
He glanced up then, smiling. ''Really, Mari, it's fine. Speak your mind.''
Unbeknownst to Sensei his insistent tugs on the stiff filing cabinet drawer rocked the potted plant, the sound muted by Mari's words. ''W-Well, if you insist... it's just that... I really lov- Sensei!''
Faster than he could even process her words the potted plant slipped, and banged against the back of his head. The hard plastic pot rolled across the floor, spilling soil as it went, but Sensei barely noticed – stumbling and wobbling dangerously. He leaned over to put a hand on the wall but misjudged the distance, falling over and sliding partway down the wall with a pained groan.
''S-Sensei!'' Mari was by his side in a heartbeat. ''A-Are you alright?! S-Stay with me!''
''Myn, I'm not gonna die from this...'' Smiling tightly Sensei reached out, attempting to pet her arm but ending up petting her shoulder, his vision overlapping slightly. ''Ow... is my head bleeding?''
Worriedly Mari straightened up and leaned over him somewhat, tenderly poking the back of his head – profusely apologising when he hissed. ''S-Sorry... um, I don't see any, but it might take a few minutes for it to start?''
Not risking nodding lest it upset his pounding headache more Sensei just grunted. ''Can you get me a wet cloth? From the bathroom down the hall?''
''Y-Yes!''
With haste befitting of someone as easily-panicked as Mari the orange-haired nun ran off, the tap of her shoes easily heard down the hall. Rushing water soon joined it, and then barely a full minute later the nun was rushing back into the room; now equipped with a damp cream-coloured cloth, one that Sensei gratefully took off her and held to the back of his head. The cold cloth was nippy but it soothed the throbbing ache there, giving him the chance to think a little.
For a long few moments they sat there in silence, their own breathing the only real sound. After a full minute Sensei felt well enough to tilt his head, turning his gaze over onto Mari herself – somewhat surprised to see a guilty look on her face. She hadn't done anything to feel guilty about, he felt, but then again Mari was always the type to blame herself for the slightest pain others felt. She could accidentally startle someone and feel guilty about it for weeks, such was her bleeding heart.
''Hey, you alright?'' Sensei murmured, nudging her.
Mari bit her lip. ''I... I'm sorry, Sensei. I shouldn't have distracted you like this.''
''This isn't your fault. Don't blame yourself, now.''
Mari however already seemed entrenched in her guilt. ''But had I not started talking, distracting you, you never would've looked away from the cabinet, you'd have seen the pot coming and could've avoided, or even caught it – now there's soil all over the floor and you're badly hurt...''
''Badly hurt is an overstatement.'' Sensei chuckled wryly, reaching up and petting her head. His vision was returning to normal now. ''It's just a bump. I don't think I'll be doing any more work today, but that's a plus in my book, heh.''
''Sensei.'' The attempted-scolding tone was ineffectual when she was smiling exasperatedly like that, simultaneously relieved he didn't hold it again her and wanting to scold him for getting out of work like this.
Chuckling softly Sensei pulled the wet cloth back. No bloodstains were to be seen, which was good. He had to praise Hina's foresight to use plastic plant pots rather than ceramic – had that fallen on him he was under no delusions he might need a quick trip to the ER, or maybe a call to a certain omnipresent healer with pink hair. He never did figure out how she always popped out of nowhere to help him when he felt unwell.
Pushing the thought of Serina from his mind Sensei slowly started to stand up. ''Mn... mind helping me back to my room? Might as well lie down for a bit.''
''Y-Yes!''
With hurried effort Mari grasped his arm and helped haul him to her feet and, though she was a lot shorter than him and didn't have the same muscle mass as him, he just needed someone to help balance him. Together they exited the office – making sure to lock it behind themselves at Mari's insistence – before making the journey up to the next floor where his lodging was. Nothing grand, closer to a small apartment than anything else, but it was enough to suit his needs.
Unlocking the front door Sensei led his assistant inside, the pristine hallway floor giving way to light-brown carpet. Pale grey walls gave it the apartment a more modern feel, emphasised by the bits of furniture that dotted the halls or the adjoined bedroom as she helped him into it. The paned windows opposite his bed let in some sunlight, but due to the angle his side of the building was cast in shade, leaving the room nice and cool – a fact he appreciated as Mari helped sit him down on his bed and laid him down on his back, the bed itself tucked into one corner and reducing the risk of him falling off it and hurting himself more.
''There...'' Mari whispered softly, straightening back up. ''Um... is there anything I can get you, Sensei?''
''No, no, it's alright.'' He murmured, exhaling a breath as he looked up at her. ''If anything I'd like you to just stay here and keep me company.''
Mari blushed at that but a small smile graced her features as well, her head bowing in acceptance. Wordlessly she removed her shoes and he kicked his own off, the nun finding a seat at the bottom of his bed and just listening to the distant sounds of vehicles outside or the birds cawing overhead. This high up all of it was muted, but that only made it more entrancing; like a subtle background track they had to consciously listen for.
After a long minute, Sensei spoke. ''By the way... what was it you wanted to tell me?''
Mari's face heated up and she immediately looked aside. ''Oh... it was nothing.''
''Clearly not.''
''Well, the last time I tried to tell you...'' The nun tapped the back of her head, reminding him of how they got into this situation in the first place.
Sensei smiled wryly at that. ''Does it look like there's any plant pots that could fall on my head here?''
Mari tried to hide her smile, she really did, but it twitched across her lips all the same. ''I suppose not. It's... it's just embarrassing to tell you, you know?''
''Then getting it off your chest will be good for you.'' Sensei countered lightly, shifting upright.
Mari turned to look at him then. Her face was warm and her eyes stared down at the bed – raising only when he reached out and cupped her chin with a finger. He could see the nervousness in her plainly; from how her pupils dilated to how she was repeatedly swallowing the spit in her mouth, undoubtedly trying to find any excuse to speak. Laying his thumb across her lips he rubbed them, making her pause, then shudder as he ran that same thumb down to her chin, stroking her soothingly.
Finally then, Mari spoke. ''I... I wanted to confess how much I... how much I care for you, Sensei.''
''M-More than a regular student, that is!'' Mari hurriedly added, flustered as she broke eye-contact. ''I know I shouldn't be saying something like this, you might not want to see me again, b-but I... I can't bear to see you sad, to see you stressed. I want to stay by your side, to be the one that wakes you in the morning with a smile, who can watch over you as you sleep and chase away your nightmares, I...''
She swallowed then, head bowing. ''I... I think I love you, Sensei.''
It was a honest confession, no hint of joke or mischief to be found, not that he would expect Mari to do any such thing. Rather than react immediately Sensei took a few moments to soak it in, not wanting to blurt something out and hurt her feelings. Mari seemingly was glad for that, using the brief silence to gather her wits, her face getting redder as she awaited either his acceptance, or his rejection.
Moments later he spoke. ''So that's what you wanted to tell me... I can see why you were hesitant about saying it during work. It's definitely distracting.''
Mari squirmed. ''S-Sorry.''
''It's alright.'' Cupping her cheek he made the nun look up at him, his other hand settling on her lower back and pulling her closer; onto his lap. Mari didn't resist, her gaze locked with his own. ''Truth be told, Mari... while I have many favourite students, and many favourite assistants... you've always been different to me. Always... higher, than the rest.''
Mari's eyes widened a little. ''Y-You mean...?''
He chuckled sheepishly, caressing her hair. ''Mm. The feeling is mutual.''
Mari stared at him for an amazed moment, as if she'd just had a dream come true – and then with a sound that could only be called pure delight she threw herself at him, her arms wrapping around him and her face burying itself in his shoulder, squeezing him tightly. Sensei didn't protest and held her in return, feeling the love she had for him pouring out in waves, such was her endless affection.
The hug lasted for a few more moments before Mari leaned back, her cheeks rosy but a smile staying glued to her lips – one that became a touch more shy as she peeked down at his lips. ''S-Sensei, could you... kiss me?''
Rather than reply with words Sensei did so by cupping her cheek and leaning in, his lips brushing over hers – and with little hesitation he sealed the deal at last. Her lips were soft against his own, parting slightly to let out a cute moan of happiness, her own hands remaining on his shoulders as she returned the kiss wholeheartedly. It was evidently her first kiss and he made sure to be gentle, letting her savour the moment for as long as she needed, waiting until she slowly pulled back.
Mari flashed him a sweet smile, squirming – and with a knowing chuckle Sensei leaned back in and gave her a second kiss. She melted into it, mewling adorably and snaking her arms around his neck, pushing herself against him just so they lips could mash together more. They pulled apart for a quick breath before invariably connecting their lips in yet another kiss, the intimacy to each action only exciting Mari more. It was so rare to see her buzzing with happiness that he couldn't help but indulge her more and more, happy to make her happy.
''Mm... ah~'' The little moans she made though were particularly sinful; taking on a lewd edge.
As were her next words. ''Sensei... I've heard some use their tongue, in a kiss... can we...?''
Her cheeks grew redder, aware on some level of how lewd that request was, but Sensei just hummed and complied – kissing her once more. This time though he introduced his tongue into the kiss, slithering it past her lips and prodding her teeth; tempting them apart and allowing his tongue to push against her own. Mari moaned, the sinful sound so erotic when his tongue was pushing and wrestling against Mari's own, the nun so out of her depth all she could do was helplessly wiggle her own tongue back against his.
The need to breathe forced them apart, but the moment they both caught their breath they were back at it again, wrestling tongues in her mouth. Mari picked up a trick or two and started to wrestle back, the motions inexperienced and uncertain, but earnest in how she tried to curl her tongue around his, his own tickling the underside of hers before pushing it about with the tip. The endless motions seemed to make the moment last forever, both of them soon pulling back from the kiss breathing heavier for it.
''Mm... Sens-'' Mari shifted then, and squeaked. ''S-Sensei?''
It took Sensei a moment to realise what Mari was startled about; becoming aware of it when she shifted her hips again, causing her inner-thigh to rub up against his crotch. His bulging crotch. ''Ah... I'm sorry.''
''No, no, it's alright...'' Mari meekly assured, looking off to the side... before peeking back at him. ''I-In fact... perhaps I could...?''
She trailed off, too embarrassed to even think about saying what she could do, but he answered all the same. ''You don't have to...''
''A-And if I want to...?'' Mari demurely countered.
At that, Sensei just caressed her cheek. ''Then I won't stop you. Just don't force yourself, alright?''
Smiling lovingly up at him Mari whispered an agreement, shifting back down the bed. She was totally out of her depth but did an admirable job, keeping calm as she unbuckled his belt and pulled his black work pants down, blushing at the mere sight of his striped boxers. Deciding to help Sensei lifted his waist up off the bed and shoved his boxers down to his thighs, revealing his erect cock – the sight of which turned Mari's face an atomic red hue, her gaze glued to his dick as she burned it into her mind.
''Mari?'' He verbally prodded her.
Startled out of her thoughts Mari whispered a sheepish apology, pulling his pants and boxers down until they were off his legs, leaving him bottomless. Only then did Mari tentatively shift on top of him, his legs parting and giving her easy access to his sizeable shaft – her hand tentatively curling around it. She leaned back a bit, perhaps startled by its firm heat, but after a second she reaffirmed her hold and slowly started to stroke it – sliding her hand up to the head before sliding back down to the base, her movements slow and almost careful.
''Like this...?'' Mari murmured, uncertain.
Sensei let out a soft sigh of bliss. ''Yes... just like that. Take your time.''
Nodding faintly Mari didn't take her eyes off of his cock, tentatively stroking him off. It didn't take her long to get used to the motion and when she did so Mari dared to get a little more bold, her grip becoming firm and her strokes a tad faster, pumping his cock. Her hand was slim and his cock was thick, forcing her to readjust her hold several times, but it never dissuaded her and the nun continued getting him off. Her other hand settled on his thigh and aimlessly stroked it, more just to keep that hand busy than anything else, but it was arousing all the same.
''What next?'' Mari broke the quiet.
''If you want, you could use your mouth.'' He offered, but didn't force her to do it. Mari was like a flower; something to be treated gently, if only because she deserved such kindness and care.
Nodding slightly Mari leaned down more on her front, embarrassed but earnest in her desire to make him feel good, to soothe his evident lust. Moving her hand down to the base of his cock Mari kept pumping him but now also planted some kisses on the very tip, one smooch after another tickling the head. He stifled a groan but couldn't entirely muffle the sound, the slightest grunt escaping him and bringing a renewed blush to Mari's face. It also emboldened the nun, her kisses becoming quicker and more deliberate, pouring her love into each and every one and making sure he felt it.
Then she started working her way down. Lips pecked down the side of his cock before circling around to the other side and kissed back up, her tongue tentatively slipped out and licked the head, she even adjusted her hand solely so she could lick every part of his cock. Only once she'd kissed and licked every bit of his cock did she return to the head, her lips kissing the tip once more before parting – spreading over the bulbous tip and sliding down to the crown of his cock, grazing over it and settling under the head.
''Slrp...'' Staring up into his eyes Mari sucked up to the tip once more, before promptly going back down his cock.
Sensei pursed his lips, trying to endure the pleasure – but one more suck was all it took to coax a deep, shaky moan out of him, pleasure written across his face. Mari blushed a rosy hue at that but was encouraged all the same, her eyes closing as she focused solely on giving him head; lovingly sucking on his cock. Gradually the nun took him in deeper, her pink lips pursing further and further down his shaft before she sucked back up it, her saliva clinging to his cock and turning each soft suck into a gentle slurp, the lewd noise sounding so loud in the otherwise-silent bedroom.
Resting his right hand upon her head Sensei gently pushed her down, moaning when Mari obliged without a hint of resistance – sucking him off with rhythmic bobs of her head. Her mouth felt so hot and wet it was incredible, pleasure searing up his shaft as those lips of hers grazed along it, teasing out all manner of grunts and groans from his throat. Despite her inexperience she was so earnest with it that it felt absolutely blissful, the wet heat of her mouth engulfing his cock repeatedly and her nose tickling his pelvis as she nearly deep-throated him.
''Ahh... Mari, don't stop...'' Sensei breathed, pleasuring pulsing up his cock. ''You're doing good...''
Delighted by that Mari continued bobbing her head with renewed enthusiasm, a soft hum escaping the back of her throat as she tilted her head a little, and then finally deep-throated him. She resisted the urge to gag for the solid second she kept him down her throat before hurriedly leaning back, her brows knitting together, but with remarkable endurance she went back to sucking him off without even breaking out into coughs; sliding her lips along his shaft faster than before.
The movement coaxed waves of heat up his shaft, doubly so when Mari slurped up to the head of his cock and popped her lips off it entirely – stroking him off with quick, full-length rolls of her wrist, her hand becoming sticky with her spit. Pre-cum gleamed across the tip of his dick until Mari licked it back up, staring into his eyes the whole while. Her curled fingers soon came to rest just under the crown of his cock, her tongue licking and lashing at it earnestly like a cat licking up its milk – before in a single seamless motion she slurped down his length, the spit in her mouth audible as she slurped up-and-down his cock in quick bobs, her fingers curling around the base of his shaft and sliding up-and-down his cock in tandem with her mouth, making sure not an inch of his dick was exposed.
The assault of pleasure it brought was too much, throbs pulsing up his cock – before he peaked. ''M-Mari!''
Mari's eyes widened as ropes of semen splattered onto her tongue, the nun freezing solid for a good second. She relaxed in the next moment, humming softly and keeping her mouth where it was – instead jerking him off with quick rolls of her wrist, helping wring out spurt after spurt of cum. It went on her tongue or shot down her throat, both inevitably swallowed down when she could catch a breath.
Until soon his orgasm waned and Mari popped her lips off of his dick, audibly swallowing the last of his seed and exhaling a heavy breath. ''Haah... d-did that feel good, Sensei?''
Sensei responded with a deep, throaty groan. ''Incredible... hah...''
Mari blushed scarlet, but smiled all the same. ''T-Thank you. I'm glad.''
Sensei smiled breathlessly at that, sitting up on his elbows. For a long moment he just sat there catching his breath, but after the amazing blow-job she'd just given, he felt compelled to pay her back. ''Here, let me...''
''Ah, Sensei...'' Mari blushed red as he held her sides and turned them around; laying her down onto the bed. ''U-Um... you don't have to.''
''And if I want to?'' He cheekily parroted the words back to her.
Mari smiled cutely at that, looking off to the side. ''I-I suppose it's okay then...''
Stifling a chuckle Sensei slid his hands up her dress, gently bundling it up around her waist until he could see her underwear. It was black, simple in colour and somewhat low-legged, but otherwise fairly unassuming. Hooking his fingers into the waistband he peeled her panties down Mari's creamy thighs and down her legs, taking the time to kiss her thighs as he went and coaxing out several soft moans from his partner, her cute squirming only endearing him more.
Tugging her black panties off of her ankles Sensei ran his hands back up her slender legs, nudging them apart and laying eyes on her pussy. She was mostly smooth, just some orange hairs above her sex, but he found her beautiful all the same – tempting him to lay down between her thighs. Just feeling his hot breath on her sex was enough to make Mari whimpered with anticipation, her breathing quick – and a soft, sweet moan tumbled off of her tongue as he licked her.
''A-Ah, Sensei~'' She whimpered out, squirming.
''Ssh.'' He soothed, kissing her folds once more.
Mari mewled but obliged, shivering as his tongue dragged itself along her slit with slow, lustful intent, teasing a stifled moan out of the student. Keeping his hands upon her thighs he kept her legs spread, taking the time to grope her thighs and occasionally lean over and kiss them too, the little bits of stimulation making Mari moan – her voice quaking when he returned his attention back to her pussy, kissing her folds or licking her slit. Despite her evident embarrassment the nun got used to the intense stimulation and settled down quickly, encouraging Sensei to be a little more bold.
Shifting his right hand over her he laid two fingers on her folds, spreading her open more – and then put his tongue to work. A sharp squeak escaped Mari before it inevitably melted down into an adorable moan, her voice trembling as his tongue drew wet circles upon her sex, teasing her entrance relentlessly. He teasingly wiggled his tongue side-to-side or moved it up further to her clit, flicking the little nub and instantly making Mari spasm, the foreign bolt of bliss so intense she moaned unashamedly – clasping a hand over her mouth an instant later.
''A-Ah, Sens- ei~'' Her voice melted as he pushed two fingers inside her womanhood. ''O-Oh... ahn... myn~''
The slew of cute sounds he fingered out of Mari only encouraged him to do it more, his twin digits thrusting and twisting around her pussy whilst his tongue attended to her clit, licking the little nub or drawing lewd circles around it, leaving a glint of spit where his tongue went. His lips moved down to her folds from time to time, kissing them or giving them the gentlest of nips, her inner-thighs proving to be an alluring target as well and getting an equal amount of treatment.
His fingers though were relentless, pumping into her in short, quickening thrusts – curling when Mari least expected it and never failing to coax a moan out of her throat, strained and embarrassed as the sound was. Smiling at that Sensei went back to teasing her lips, daring to kiss the little nub and sucking lightly, his nose tickled by her orange pubes as he moved his head side-to-side languidly, taking his time with pleasuring her. He paid close attention to her reactions as well, waiting until her body started to tense before slowing his movements, giving her enough time to cool off before he immediately sped back up again, teasing her but letting her enjoy it all the same.
''Don't hide your voice.'' Sensei hummed against her clit, moving down – his fingers tugged out and spreading her nether lips apart. ''I want to hear it.''
Then without another word he went back to tongue-fucking the virgin nun. She gasped, clutching at the sheets on either side of her and pulling them for support, her stomach depressing and her upper-back lifting off of the bed. She went slack in the next moment but tensed in the one after that; pleasure rippling through her body in waves as he ate her out, the sloppy sounds of his tongue turning her on more as he lapped up her juices, making a mess across his chin he made no move to wipe up yet.
The invisible knot inside her stomach grew tighter as he started wiggling his tongue about in a vague, erratic figure-eight; the motion more an idle spice-up than a proper technique, but one that made Mari moan all the same – her voice rising in pitch as he groped her thighs at the same time. His nose brushed against her clit and his breath washed over her quivering, dripping sex in waves, no longer giving her a moment to catch her breath, to relax, the pressure inside her rapidly mounting into a foreign, intense rush-
''S-SENSEI!''
-until with a girlish squeal Mari orgasmed, throwing her head back and pushing his face into her sex. Her legs tensed and her body lifted and dropped back onto the bed repeatedly, desperately humping his body as she had her first ever orgasm, and orgasmed hard. The intensity of it purged her mind of all thought and left her mouth hanging open in a near-ahegao of bliss, a very unsaintly look for such a pure nun that only made it more arousing for Sensei.
Leaning back from her crotch Sensei took a moment to wipe his chin dry, admiring her glistening pussy and flushed face – nudging her thigh and helping snap her out of it. ''Like it?''
Mari blushed scarlet, a half-giggle, half-laugh escaping her. ''Y-Yes... it felt as if I was on cloud nine... erm, please don't tell anyone I said that, that's embarrassing, actually...''
Sensei just hummed, stroking her thigh. His cock stood erect, recharged after the quick break; something that Mari herself had noticed.
''U-Um... Sensei...'' Still out of breath but with tentative affection in her eyes she opened her legs once more. ''...would you be my first?''
He smiled warmly down at her. ''Of course.''
Mari smiled back, offering her left hand and interlocking her fingers with his own; holding hands as he shifted between her thighs. Holding his cock in his right he guided himself to her entrance, the head of his cock pressing against her orange tuft before sliding down over her clit and down to her entrance, pressing firmly against it. He met some resistance despite how wet she was but he put a little more effort into it, finally sinking in – and then pushed his shaft inside her.
Blissful, ungodly hot tightness clamped down on him in an instant. It felt like he just stuck his dick in a furnace, such was her heat; her inner walls constricting his shaft as he buried himself in inch by inch, a moan bubbling up his throat. Beneath him Mari let out a softer whimper, grimacing, but otherwise didn't seem to be in much pain – her arousal helping ease his dick in despite how narrow her pussy was, her walls forced apart by his sizeable shaft.
Until soon he was most of the way inside her. Sensei paused, giving the nun some time to adjust to losing her first; but with a tender, loving smile she just reached up and caressed his cheek, luring him down until their lips could meet in a loving kiss. Leaning down on his elbow he dragged the kiss out, their interlocked hands squeezing each other lovingly throughout. Only after a prolonged kiss did they draw apart, a mutual breath escaping them and their gazes locked onto one another.
''I'll move now.'' He whispered to her.
''Mm.'' Nodding Mari leaned up and gave him one last kiss to the kiss. ''Be gentle.''
Humming an agreement Sensei leaned up a little; balancing himself as he slowly pulled out of her tight, formerly-virgin pussy – and with a groan buried himself back inside her. His movements were stiff and slow, struggling not to just lose himself in the pleasurable tightness clamping down on his dick, but one look at Mari's pleasure-filled visage was more than enough to keep him grounded. He continued to keep a close eye on her as he started to pick up speed, falling into a rhythm that saw his cock spearing deep into her clenching tunnel, the last inch of his cock pushing in too and filling her to the brim.
Mari moaned deeply at the feeling, back arching off of the bed briefly before she flopped back down again; total bliss on her face as her pussy was filled to the brim. Sensei didn't stop nor slow though, his cock stirring up her quivering insides with every rock of his waist, pumping into her clenching depths and lightly slapping his flesh against hers. When he put more force into his hips his pelvis practically grinded up against her clit, the little spike of pleasure easily worming another adorable mewl out of Mari, her eyelashes fluttering and her eyes soon screwing shut from the intensity of it.
''Ah, a-ahh~'' Cute moans spilled from Mari's lips. ''Sensei, I-I can feel you... deep inside me, it feels so h-huge~''
The way her words stuttered and slowed, drawing out into arousing whines, turned him on more than he expected. Rather than respond he did so by moving his right hand further up her body, bundling her dress up around her stomach until he could hold her waist – his other hand soon joining it. With both hands caressing her sides he picked up the pace, plunging himself into the gasping nun and hitting her innermost parts with his cock, soon fucking a cry of pleasure out of Mari's lips.
Emboldened by the sound he kept up the pace, being mindful not to be too rough lest he hurt her – she was a lot more petite than he was, after all, and her pussy felt so narrow compared to his cock. That though only made it more pleasurable for them both, his cock scraping her walls every time he jammed it into her tight hole, stuffing her with his meat. He lifted her lower half off the bed slightly so he could get a better angle too, his thrusts driving himself in just the right manner to rub against a sweet spot, fucking higher-pitches moans out of the nun, her eyes screwing shut.
Shifting his hands down he held her hips, grunting as he slammed into her. ''M-Mari... you doing alright?''
Unable to speak Mari just jerked her head in a nod, breathing sharp and quick between moans. Her wet walls constricted his cock, the tight clamp purging his mind of all thoughts every time it happened, instinct taking over and controlling his movements. Heat rolled up his cock in waves and grew more powerful by the second, pressure climbing his shaft and leaving him grunting, barely resisting the enthralling tidal wave of pleasure begging for release-
''Ah, a-ah~! S-Sensei! Sen- SEI~!''
That became impossible as Mari's cute cry pierced the air, and the nun climaxed for the second time that day. Her pussy tightened sharply around him, the ungodly tight squeezing pushing him to the edge and forcing a shout from his throat – and with a gasp he slammed back inside her on instinct alone and delivered a thick shot of semen into her depths, cumming inside the nun.
Mari writhed from the sensation, eyes wide and lips ajar as she felt him spurt in her. He pulled back, the tip staying inside her as he spurted more in her, every throb of his cock punctuating another rope of warmth in her - and just before another throb he pulled out, letting the tip slide from her wet folds and spurt a rope of sticky white cum up into her orange pubes, another smaller spurt joining it a second later.
''Ah... hah... haah...'' Panting so heavily it took Mari a good few moments to be able to speak. ''Sensei...''
Her hand slid to her stomach, and a smile curled at her lips, sweet and full of love. ''You better take responsibility, hehe~''
A low chuckle answered her; one that became muted as their lips met in a kiss and they rolled over, his cock soon to graze her nether lips and sink back inside her warmth; the two of them doing it again with a more deliberate intent.
