A/N: Had this one in stock for some time now - and I'm aware I've been saying that for the last week or two, but I've been posting a lot of fics I had on the reserve list but never got around to posting, hence the constant utterance.

That said, I do hope you enjoy some Mutsuki getting corrected lewds~

Corrective Punishment

It was a fairly quiet day for Sensei, all things considered.

A distinct rarity, that he knew, so he was determined to get through what little work he had so he could spend the remainder of the day out with some of his students. Such a plan, though noble, quickly found itself shelved as a certain gremlin came to visit his office and 'help out'. Mutsuki.

Whether she actually came to help out or just to tease him, that he didn't know. What he did know was that the elf-eared tease truly lived up to her reputation, constantly teasing him throughout the day and granting him very little time to himself. Sometimes she struck up a curious conversation, other times she called him name and flipped the back of her skirt up, revealing a pair of yellow panties that hugged her small rear – and if he dared stare for more than a second she giggled to herself, visibly smug.

After hours and hours of enduring it his patience quickly started to run thin. He could take a little teasing, he knew. He could handle some jabs at him or a bit of flirting. But for hours upon hours, wasting his time and constantly distracting him from actually getting through his work? It was really, really starting to get on his nerves.

''Mutsuki, please calm down.'' Sensei uttered out tersely as he signed off another document, eyes on the paper and not the teasing student halfway across the room, bored and playing with some folders. ''If you're not here to help, then leave.''

''Aw, don't be so uptight Sensei~'' The elf-eared Gehenna student replied, smirking. ''You've got a cute girl just lazing about in your office with nobody around. Isn't that something to enjoy?''

There was a playfulness to her words that just invited speculation, his thoughts naturally turning to a more lewd place before he firmly shook his head, banishing such lewd thoughts. That was made much harder though when Mutsuki winked his way and pinched the hem of her skirt, lifting it up just enough to show off her panties again, making him purse his lips and refocus back on the papers before him.

For another minute he worked away, his fingers tapping keys and his pen scratching across paper, marking quizzes or signing forms... when suddenly he felt movement by his knees.

Then less than a second later hands grasped his belt, unbuckling it. Startled Sensei leaned back into his chair and stared down his front, shocked to see Mutsuki under his desk; the petite mischief-maker on all fours and smirking mirthfully up at him, even as her lithe fingers finally got his belt buckle loose and let his belt hang apart – leaving nothing to stop her from pinching his zipper and pulling it straight down.

''M-Mutsuki?!'' Sensei called out, alarmed.

''Aw, don't look so flustered Sensei~'' Mutsuki tittered with amusement. ''I'm just gonna help you relax, that's all~''

''T-That's not the problem here!''

''Oh? So you're fine with me blowing you otherwise?''

''Ye- no! No, and stop with your- mn!?''

His attempt at scolding was harshly cut off as Mutsuki slipped her hand into his tight-fitting dress pants, undoing the front button of his boxers and pulling his cock out. To his embarrassment he was already quite hard, his dick standing at attention before her – something that visibly amused his gremlin of a student, her fingers curling around his swollen shaft and stroking it slowly.

It felt good. Far better than his own hand, in fact. Her touch was dainty and her skin soft as she squeezed his cock, stroking up to the head and then down to the base in a smooth, rolling motion, forcing a moan from his lips. The sound only emboldened Mutsuki to do more, another little snicker escaping her as she continued stroking his cock, using her other hand to push away his when he tried to stop her.

''Nn... Mutsuki, stop-''

''Hm? But why? You're clearly enjoying this, Sensei~'' Mutsuki teased.

Sensei had no retort to that beyond a strained groan – one that spiked into a gasp as Mutsuki suddenly leaned in and licked the tip. Her tongue was wet with spit, a fact he vividly learned as she dragged the appendage over the tip again and again, flicking it earnestly and forcing all manner of tight moans from his lips, the sounds filling the office despite his best attempt to quell them. What if someone was to come by right then and there? Or if someone like Kotama had installed audio devices to listen in? Or if Hare hacked the cameras? So many possibilities, so many risks.

Risks that Mutsuki seemed entirely oblivious to. Or rather, uncaring of. Something she proved as she wrapped her right arm around his thigh and kissed the tip – before taking him into her mouth. It felt hot, intense, and oh so wet; frying his mind for a solid second as pure pleasure overtook all rational thought, unable to think of anything but the wet warmth surrounding his cock. Her lips grazed the shaft down two-thirds of the way before she sucked smoothly back up to the tip, leaving spit clinging to his shaft in their wake before she inevitably went back down again.

Quite quickly the Gehenna student found her rhythm, humming a merry tune as she slurped his shaft. He gritted his teeth and tried to push her away, palm on her forehead, but Mutsuki used her free hand to bat his away – using that same hand to grab his shaft and guide it slightly to the side, allowing the tip to thrust in and bulge her cheek out. The sight alone burned itself into his memory but the feeling of her fleshy cheek rubbing against his cock-head felt utterly divine, his dick throbbing in her mouth from the blissful sensation.

''A-Ah... fuck...'' Sensei cursed under his breath, groaning.

Mutsuki just hummed, her eyes crinkling with mirth as she continued bobbing her head, those slim pink lips of hers raking along his cock and granting him pleasures unrivalled. Soon she aligned his cock with her throat though and went deeper, his cock-head thrusting over her tongue – until soon he hit the back of her throat. The sensation made her gag and him moan; the latter becoming much louder as Mutsuki repeatedly took him down to the back of her throat, her nose brushing against his groin as she throated him.

''Ghk, guh, mghk, hurk...!''

An assortment of hot wet sounds choked out of Mutsuki, yet the Gehenna girl didn't slow nor stop – going as far as to wrap her other arm around his thigh too, stopping him from shoving her away as she ruthlessly throated him. Sensei couldn't even find it in him to fight back, gasps of pleasure escaping him as he grabbed her head and yanked her down into his crotch; shoving his cock down her throat and feeling her throat muscles clench around it, pushing him to his peak-

''Fuck!''

-when with a hot curse, he busted his load straight down her throat. Mutsuki spasmed momentarily but didn't fight his hold; audibly gulping down gush after gush of semen that poured down her throat like molten magma, bitter as it was. The boiling embrace of her mouth and throat only served to coax out more of his semen too, his dick twitching mightily against her tongue as the appendage pushed up against the underside, working out all of his load.

Until with a staggered groan he released her head, and Mutsuki slurped her lips up and off of the tip – panting heavily immediately after. Slowly his white-haired student unwound her arms from his legs and wiped her chin dry of spit, a light twinkle of mirth in her eyes that only serve to reignite his prior emotions. Lust. Lust, and righteous anger.

''You...!''

Mutsuki squeaked as he suddenly grabbed her by the front of her dress, dragging her out from under his desk. Uncaring for decorum in that moment he grabbed her bodily, one hand grabbing her crotch and the other her chest, restraining her and groping her in equal measure. Mutsuki put up a token struggle but could do little to stop him as he shoved her against his desk, bending her over it at the waist and yanking the back of her skirt up, showing off her small perky ass hugged by a pair of yellow panties.

Panties that were unceremoniously grabbed and yanked down to her thighs, exposing her small rear in better detail along with her smooth, delicate-looking slit. Sensei spent only a single second to admire it before he stumbled behind her, keeping her pinned down with one hand whilst his right guided his cock against her nether lips, rubbing along her slit once, twice, thrice-

-and then at last he slammed inside of Mutsuki's pussy. His student cried out but not in terrible pain, and when he glanced up he noticed that despite a twinge of discomfort, she was grinning. Like this had been her plan all along.

''You brat...!'' Sensei growled, bucking his hips. ''Teasing me all day, you need... hnf, c-correction!''

Mutsuki offered no response other than a moan, making him growl and thrust harder. Her pussy offered only token resistance to his thick cock as it slammed between her folds, the molten warmth of her insides easily purging his mind of any other rational thought; able to do naught but buck his hips and stick his dick inside of Mutsuki's tight, willing pussy. The thought just irritated him more – he'd just bent her over his desk and shoved his cock in her, yet she was still smirking like she'd won. It infuriated him.

He took out that simmering irritation on her. Holding her lower back down against his desk his other hand settled on her hip, keeping her steady as he buried his cock into her – unable to stop himself from moaning as he felt her pussy clamp so tightly around him, like a slippery vice that was begging for dick. He provided it in spades, his thrusts harsh and only becoming more so as he went balls-deep in the petite Gehenna girl, his groin smacking up against her ass too and making ripples echo across her flesh.

''Did you plan this?'' Sensei growled out, shifting a hand down to grope her ass before giving it a firm smack. ''Huh?!''

''M-Mm!'' Mutsuki moaned out, peeking back at him with a cheeky smirk. ''Maybe~''

''You little slut!'' Sensei growled out, thrusting hard and making her cry out in pleasure.

Yet if anything the rough, almost insulting words seemed to turn Mutsuki on more; her pussy clamping tightly around his cock as if begging for more. And more Sensei gave, a growl bubbling out past his lips as he slammed his cock between her nether lips and hit her innermost parts again and again, every impact against her ass jerking her up against his desk and making her moan in shameless ecstasy.

The thought was equal parts arousing and irritating, enticing him to keep fucking her – but after such an amazing blowjob he was struggling to endure, pleasure rapidly surging down his length as he slammed between her glistening folds. He didn't relent though and certainly didn't prepare to pull out, a bubbling growl arising from the back of his throat as he kept railing her raw, his orgasm imminent-

-and then with a sharp shout he slammed inside Mutsuki and came, busting a thick load right up against her cervix. His student squealed in utter ecstasy as he creampied her, legs lifting off of the floor as he pinned her waist between him and the desk; every throb of his cock preluding the next load he shot inside of her – her clenching pussy helping squeeze it all out of him. Slowly some of the excess began to seep out around his shaft, trailing a thin line down her groin before dripping off onto the floor.

Then with a sharp exhale Sensei pulled out. Mutsuki moaned and went limp against his desk, her skirt remaining hiked up and presenting a nice view of her peachy ass cheeks; her right one reddening from the multiple spanks he'd given. Her pussy wept his seed in a steady flow and her legs hung near-limp, making no move to stand up.

Not until Sensei growled, sitting down in his chair. ''Stand up.''

Mutsuki moaned but complied, wobbling briefly but turning to face him, panting.

''Now strip.''

Pinkness painted itself across Mutsuki's cheeks, but with a wry smirk she complied. In seconds her skirt fell around her ankles, followed soon by her top and bra, baring her small, near-flat tits to him. Her panties dropped around her ankles and she stepped out of her clothes without losing her cheeky expression, going as far as to slip out of her shoes and socks too, leaving herself utterly nude in front of him. The thought made him shudder with arousal, the fact that he had one of his students naked in his office turning him on more than he thought possible.

''Ride me.'' He then ordered, voice low but commanding.

Mutsuki complied. With only a hint of embarrassment the cheeky bomb expert climbed onto his lap and laid her left hand upon his shoulder, her other hand dipping down between their bodies to grasp at his cock. Her touch was dainty but with how sensitive he was her mere touch left him twitching with lust, doubly so when she guided the tip up to her pussy; rubbing the head along her dripping-wet slit.

Then the tip slid between her petals, and he moaned as he was back inside his student's tight pussy. Mutsuki was more than enthusiastic enough for his tastes, mewling happily as she impaled herself inch by inch until he was fully inside her, wasting no time in lifting herself up and dropping herself back down, bouncing onto his cock slowly at first but quickly building momentum – wet enough that she clearly felt no pain. Sensei groaned at the idea and grabbed her ass, admiring her small behind before bringing his right hand down in a spank, eliciting a cute yelp from Mutsuki.

A yelp he stifled with a kiss. If she was startled by it Mutsuki didn't show it; merely humming as she reciprocated. There was no love or anything to it, just pure senseless want, but Mutsuki was perfectly fine with that and introduced her tongue into the mix – tempting his own past his teeth. Even as his student rode him their tongues tangled between their mouths, the kiss hot and wild but sill making him throb with need inside of her, the tight squeezes of her loins threatening to make him bust a second time so soon.

''Fuck, you're so tight.'' Sensei grunted; pulling back from the kiss and glaring lustfully at his cheeky student.

''Hehe~ Thank- mn~!'' Mutsuki's cheeky retorted melted into a moan as he spanked her, masochistic delight shining in her pink eyes.

Something that tempted the Commander to grab her by her sides – and then stand up. Taken aback Mutsuki yelped and clutched onto him with both arms and legs, only for a moan to be fucked from her lips as he started yanking her up-and-down his dick like she was his personal onahole, her snug pussy roughly stuffed with his dick and the tip battering up against her cervix. The initial shock wore off fast and more moans swiftly spilled past Mutsuki's lips, only growing louder when Sensei started to walk out past his desk and over to the nearby window.

A window he pushed Mutsuki up against, growling as he reclaimed her lips in a kiss and slammed his cock into her sopping pussy, the raw smacks of flesh echoing through his office. They were located so high up he doubted anyone would see but the thought, the risk of someone seeing him balls-deep in Mutsuki, fanned the flames in his loins and made him fuck the cheeky brat all the harder, railing her with gusto.

''M-Mmn~! Sensei~!'' Mutsuki wailed against his lips.

''Shut up! Teasing me all day, sucking me off when I tell you to stop, you, hnf, d-deserve this you little slut!'' Sensei growled against her lips, pounding her for all she was worth. ''Shit! G-Get pregn- NNT!''

He didn't even get a chance to say the famous line before his orgasm hit; pleasure shooting up his cock right before he bottomed out, busting the thickest load of his life inside of Mutsuki. His petite and stripped-bare student squealed in return, convulsing in his hold as she orgasmed with him; only enticing him to buck his hips in a string of short, frantic thrusts and empty his balls into her depths, her tight pussy helping squeeze out of all of his seed and delivering it into her womb.

Mutsuki shuddered, her loins tightening and relaxing at erratic intervals – until with a tight sigh he pulled out. The air felt cool compared to the heat of her pussy but Sensei hardly cared in that moment; too busy panting for breath to think coherently and just staring at Mutsuki's smooth, glistening sex as his cum drooled out of it.

''Hyaah~ You came so much, Sensei~'' Mutsuki mewled out breathily.

Sensei just grunted back, lowering her down onto the floor. Mutsuki wobbled on weakened legs for a second before steadying herself, flashing him a cheeky smile as she shambled back over to where she'd stripped naked. He followed her with his eyes, his dick soft but his lust still simmering beneath the surface as he stared at that pert, enticing ass of hers, her lithe frame slowly covered back up as she put her clothes on and brushed her hair back with her hands, looking little worse for wear by the end of it.

''Hehe, I'll be back tomorrow Sensei.'' Mutsuki winked back at him. ''Maybe then you can 'teach' me more about making babies~''

She licked her lips and flicked her skirt up – and revealed she wasn't wearing her panties, letting him catch a glimpse of his cum drooling down her inner-thighs.

''See ya~''

Sensei only groaned back, watching as his mischievous student skipped out of his office – already preparing what 'punishment' he wanted to give her the next day.

If she was fine with teasing him, then she would be fine reaping the consequences, that he was sure of.
