#monster school

You have a crush.

A very, massive, humongous crush.

A wonderful crush on your monster biology teacher, Dr Lis.

Whenever a student struggled with the complexities of biology, he took his time to explain in a way that anyone could understand. He excelled at his job and was passionate about teaching. Dr Lis was intelligent, patient and gentle. But beneath that academic poise, you found yourself wondering if that same patience would apply to… other things.

Those were the things that made you fall hard for Dr Lis, especially his appearance; he was a beautiful fox guy with dark fur that had purple and pink hues here and there. His eyes were a mix of violet and bright pink, and you could've sworn they sometimes flickered in certain moments. Especially when they were directed at you...

But it is a secret, you don't want anyone to know. You don't want to ruin his reputation! So all you do is pretend to be a teacher's pet, in an academic sense!

No one knows of your secret crush.

Or so you thought...

Recently, you started to notice the subtle signs—small, flickering changes in Dr Lis’s composure. Every time you answer a question correctly, his thick, distinguished white tail gives a sharp, involuntary twitch…

After each homework paper return, the Foxian teacher gives you a mysterious smirk that barely exposes his fangs, and you find enigmatic notes on them that are a bit more personal.

"The anatomical rendering you did of the werewolf pelvic region was… impressively firm. You have a keen eye for where the true strength of a creature lies."

"Your description of vampiric vision is masterful; it felt almost hypnotic to read. It makes me wonder what else you see when you look at someone so closely…"

"Your knowledge of aphrodisiatic fluids is exceptional. You seem to have a natural instinct for the chemistry of desire—a very dangerous talent for a student to have."

You also noticed how Dr Lis lingered a moment longer whenever he leaned over your shoulder during a dissection, or as you examined cells and samples under the microscope. You could feel the radiating heat of his body and the faint, earthy scent of his fur, turning a simple biology lesson into an exercise in holding your breath.

Maybe this was a sign...

You decided to be bold. You slipped into the classroom after the final bell, your heart thumping a rhythm that matched your confidence. You watched his velvety fox ear twitch—a sharp, directional snap that told you he’d caught your scent long before you spoke.

"Soooooo, Dr Lis~ I know we had a class on Kitsune beasts, buuuuut~" you drawled, a playful smirk dancing on your lips. "I’m not quite sure I grasped how their reproduction works."

You sank into the chair by his desk, steepling your fingers and resting your cheek against them, looking up at him through your lashes. "Since you’re a fox-beast yourself, I hoped you could explain it in greater detail to me… I’m really struggling to wrap my head around it~"

"My sweet butterfly," he hummed, the sound vibrating with a knowing smirk on those devilishly tempting lips. "I am quite certain you are already well-versed in their reproduction process…"

Dr Lis levelled the stack of papers in his hands with slow, deliberate precision. You couldn't help but let your eyes linger on his long, delicate fingers—the way they moved was as hypnotic as his scent. You forced a swallow, the saliva thick in your throat, as the silence in the classroom began to sizzle.

In those seconds, the sterile, sharp smell of the lab was completely drowned out by his scent—something musky and sweet, like crushed dark plums and a trace of expensive incense. It was a heavy, intoxicating aroma that made your heart hammer against your ribs.

The presence of the Foxian teacher was overpowering, a weight that felt as heavy as his scent. Your wings vibrated with a frantic, hidden energy, spilling a fine shimmer of biological dust onto the floor, while your antennae shivered under his dominating gaze. You squirmed softly in your seat, your cheeks and eyes flushing a deep, betrayed pink that mirrored the hues of his own fur.

You refused to submit completely. Steeling your nerves, you crossed your arms beneath your plum-colored chest, a gesture that served only to present yourself more boldly. Your red school tie draped over your bosom, outlining your form as you shifted your weight. With a deliberate slowness, you crossed one leg over the other, allowing your skirt to slide juuuuust enough to reveal the curve of your thick, succulent thighs. You weren't just a student anymore; you were a challenge.

Dr Lis read your nonverbal message and smirked, deliberately exposing his fangs this time. He leaned in close—trapping you by placing the stack of papers on the desk behind your back—until his presence was even more delicious than you had anticipated. His sharp, vertical pupils never left your frame.

"Perhaps..." he purred, his eyes narrowing as his nose stopped mere millimetres from yours, "you want more... practical examples, hm~?"

Your face flushed a bright, burning magenta, and you could barely register the way your antennae were flitting in a shy, frantic rhythm against the air between you.

Since you struggled to speak, Dr Lis outstretched his arm to caress your smooth cheek. The touch was agonisingly gentle—sensual enough to send your mind racing and your heart into a frantic, drumming rhythm. You hadn't expected it to go this far; not that you wanted to complain, but you weren't ready for the sheer weight of his attention! Your poor, beating heart felt as though it couldn't possibly hold such a surge of excitement without breaking.

You tried to ground yourself by looking directly into Dr Lis’s eyes; that was your mistake. The moment your widened gaze locked onto his, you felt utterly hypnotised, pulled toward him by a force stronger than gravity. The rest of the world dissolved into the shadows, your vision tunnelling until there was nothing left but the violet glow of his eyes and the intoxicating scent of dark plums.

Like a moth drawn into a flame.

Then you felt it—something impossibly soft brushing against your back. You jolted at the sensation, your head turning involuntarily to find your teacher’s thick, white fox tail winding around you, embracing your waist from behind. While you were momentarily entranced by the luminescent glow of the fur and its twirling tuft tip, Dr Lis took his advantage. He leaned in until his hot, steamy breath tickled the sensitive curve of your human ear, the heat of it so intense you had to bite back a moan.

"Firrrrst~" he began, the word vibrating with the unholiest, deepest purr you’d ever heard, "you must seduce your mate... or your prey, whichever you prefer, dear~"

Dr Lis’s long, delicate fingers snaked up your neck, finally coming to rest in an animalistic caress against your throat. You felt the slight pressure of his palm—not enough to hurt, but enough to make you hyper-aware of your own pulse. As his palm settled against your skin, a fresh shiver of biological dust escaped your wings, coating his dark sleeve in a faint, silver-plum shimmer—a physical mark of your surrender.

"You need to make them feel relaxed... safe," he whispered, the tip of his nose nudging at your jawline in a light, rhythmic nuzzle. "We Kitsune beasts can feel our mate's pulse, their every breath... and exactly how high their arousal has spiked~"

At his last words, you froze. The realisation hit you like a physical weight—had he figured out your crush? How long had he been watching you, scenting your desire from across the classroom? You weren't sure if it was the sting of embarrassment or the sheer electricity of excitement, but one thing was certain: you loved the feeling of being his prey...

The Foxian teacher continued to trace your sensitive pulse with his expert nose. "You smell so divine, my sweet darling~" he purred against the shell of your ear, his voice a low, vibrating hum. "So butterfline... so lepidopterous~"

He continued to murmur these sweet, scientific endearments while his fingertip began to trace your rami. He moved with a scholar's precision, parting each delicate branch like the barbs of a feather’s vane, smoothing them like the bristles of a fine brush. Each stroke sent a jolt of pure, unadulterated sensation straight to your core.

Dr Lis exhaled directly into your antenna, the heat of his steamy breath condensing against the delicate rami until your feathery whiskers felt heavy, warm, and wet. You trembled like a lone autumn leaf caught in a storm—or rather, your antennae vibrated with such intensity they looked like leaves tossed by a sudden, violent gale. The sensation was overwhelming, a flood of warmth that made your entire body feel dangerously fluid.

Now that the Foxian was this close, his scent became an intoxicating, lustful weight in your nasal cavities. You had always known his mysterious, light musky aroma, but now—held in his shadow—you could distinguish the delicate top notes of crushed sakura blossoms. Beneath that lay something deeper and slightly pungent: the tart sweetness of dark cherries and the comforting, simmering spice of baked apples. It was a scent that didn't just fill your head; it settled into your very marrow, demanding you stay right where you were.

All this sensory overload finally broke you, forcing a pathetic, whimpering moan from your throat—though you didn't think of complaining. You felt raw, exposed, and utterly humiliated. Then, the sharp sound of footsteps echoed from behind the classroom door.

You froze, your heart stopping, but your stillness was rendered useless. Dr Lis suddenly yanked your antennae—not harshly enough to damage the rami, but firm enough to make you tremble and let out a sharp squeak. Before you could react, he manhandled you, pulling you off the chair and pinning you down until your head was pressed against the cool, sterile floor. Horrified, you squeezed your eyes shut, praying that whichever students were lingering in the hallway hadn't heard your betraying sounds...

"D-Dr Lis... t-there are people around..." you whispered, your voice barely a breath, but his sharp Kitsune hearing caught every trembling syllable.

He smirked, the expression dark and predatory, and tightened his grip around your antennae just enough to send a fresh wave of heat through your frame. He leaned down, his lips brushing the shell of your human ear as he whispered huskily:

"And? We are having an important lesson here, my dear mothling~ If you want no one to interrupt us, you’d better stay very, very quiet then~"

Those were the words of your crush—the very Foxian who made your heart rumble and squeal like a pathetic schoolgirl. The humiliation coiled deep inside you, growing heavy and thick, only to turn into a sharper embarrassment as you realised your body was betraying you completely. Down below, you felt the unmistakable, heavy heat of your panties becoming obscenely drenched, a physical testament to how much you craved his "important lesson."

Then, you felt something slithering beneath you. You realised with a jolt that it was Dr Lis’s tail, teasingly brushing against you to feel the damp heat of your drenched panties. The mischievous, luminescent tuft began to draw slow, deliberate circles over your clothed clit, sending sparks of fire through your nerves. Meanwhile, he shifted his weight, his upper torso looming over you as he nuzzled deep into your ink-black hair. You let out a shaky breath as his true goal became clear: he was moving to lick the base of your antennae—the place where you were most agonisingly sensitive.

You shuddered violently, your moth-wings flitting in a frantic, spasmic rhythm from the sheer weight of the overstimulation. A thick cloud of shimmering dust erupted from your wings, coating both you and your crush in a fine, glitter-plum powder. Your bright magenta eyes rolled back into your head as you bit your lip—hard enough to taste the metallic, chalky tang of your own blood. The sharp sting and the strange flavour only served to heighten your arousal further, sending a surge through your nerves that made your brain nearly short-circuit.

"Then..." you finally heard Dr Lis' silken voice, a sound that mixed with the rush of pleasure until it became just another intoxicating ingredient in the arousal cocktail brewing in your brain. His hand coiled firmly around your waist, his long fingers sinking into your soft skin as he began fondling your chubs with a slow, possessive rhythm. "We prepare our prey for mating~"

You could feel your erogenous zones swelling, pulsing with a sensitivity that was becoming almost unbearable. Then, Dr Lis rolled his hips, brushing the heavy, hardened heat of his bulge against your soaking groin.

You arched your back painfully, your spine snapping into a desperate curve as a deep, guttural moan tore from your throat. All pretence of the "student" vanished; your tongue lolled out, a string of lewd saliva dripping onto the pristine, clean floor as your body completely surrendered to the Kitsune’s rhythm.

You tried to push away the terrifying possibility of being exposed, but the danger only served to fuel your sinful, insectile brain. Your violent shivers were expertly restrained by the Foxian’s strong yet delicate arm, pinning you to the floor as he maintained control by pulling your antennae.

He began hungrily sucking on your scapes, his tongue swirling around the sensitive bases until your mind went blank. In response, your body began to betray you by exuding a heavy cloud of sex pheromones that filled the small space between you. The scent made you feel mellow and docile, yet left your core desperate and aching for the final strike of Dr Lis.

The atmosphere was now completely infused with the heavy, cloying scent of sex and pheromones—the perfect biological setting for mating. You could sense how your scent was intoxicating the beast above you; his pupils blown wide as his tail began sliding your panties down with agonisingly teasing slowness.

Even as his hands moved with deliberate care, his dry humping grew more relentless, a primal rhythm that demanded surrender. The moment you felt his soft, thick fur press against the sensitive skin of your thick thighs and ass, your knees finally gave way, leaving you completely at the mercy of the Foxian’s hunger.

Then, you heard a solid growl you didn't recognise.

"Brace yourself, mothling."

You weren’t given a single second to react before your core was instantly filled with a delicious hardness, striking every one of your sweet spots at once. You tried to scream, the sound tearing from your throat, but beautiful, long fingers thrusted into your mouth, muffling your euphorically defiant moan. As the beast claimed you, your antennae were pulled and gripped with a new, bruising intensity, and you felt the sharp fangs pierce the skin of your shoulder, tethering you in a surge of pain and pure ecstasy.

The classroom was now a sanctuary of lewd, primal sounds—a hot cacophony that echoed off the cold lab tables. There was the frantic, soft flutter of lepidopteran wings against the floor, the rustle of thick fox fur, and the rhythmic, skin-to-skin plapping of the Foxian’s relentless pace. This symphony of the beast was underscored by your own broken whimpers and his low, gentle growls, all while the thick scent of sex and pheromones rose around you like a sweet, suffocating intoxication.

The tension was tightening to a breaking point, the knot in your belly coiling with a sharp, masochistic pleasure as your teacher pinned you harder to the floor by your throat. Dr Lis picked up the pace, his movements becoming a frantic, rhythmic blur as he chased his own release.

The closer he got to the edge, the harder he pinned you and the deeper he thrusted, his desperation mirroring your own. Meanwhile, his luminescent tail caressed your shuddering body with its strangely cold, glowing fur—a dizzying, electric contrast to the searing heat of the beast currently claiming you.

Finally, Dr Lis delivered one last, violent thrust that almost knocked the breath from your lungs. His Kitsune knot plopped firmly into place right inside you, the sudden expansion making you choke on an inaudible gasp as your mind finally snapped.

He spilt his warm seed deep inside your core, and you could feel his cock pulsating deliciously against your vaginal walls, a rhythmic thrumming that matched the frantic beating of your own heart. He kept you pinned firmly to the cool floor, his weight and the biological lock of the knot claiming you completely, leaving you anchored to the beast in a state of helpless, liquid bliss.

While the Foxian was still filling you up, he began using his long, wet tongue to lick your sweat-covered skin. The act seemed odd, almost primal at first, but you soon realised the secret of his Kitsune biology: his saliva had a profound cooling effect. As Dr Lis licked your neck and shoulders, the "burn" of the animalistic mating began to fade, replaced by a soothing, icy relief that calmed your overstimulated nerves.

Soon, with agonising and painful slowness, Dr Lis finally removed himself from your pretty, abused hole. The sudden void left you feeling cold and hollow, and you let out a pathetic, high-pitched whine, your body already yearning for the return of his heavy Kitsune cock. You felt ruined, yet entirely his—a moth caught in the silver silk of a Foxian’s desire.

Then, you felt his massive frame looming over you once more, his presence feeling even more dangerous and intoxicating than before. He leaned down, his voice a sultry purr against your human ear:

"I shouldn't stay too long inside you, my butterfline dear~ We wouldn't like you to get pregnant, now, would we~?"

Your eyes widened and your cheeks burned a fierce magenta. Dr Lis knew. He knew your anatomy—the complex, hidden secrets of your reproduction. He knew that for a "mothling" to conceive, you needed to be plugged by the shaft—"corked"—ideally for the entire night. The realisation that he had intentionally studied how to "fill" you without "claiming" you permanently made your brain melt and spin in a dizzying, pleasant haze.

Lost in a heavy, euphoric daze, you barely noticed that you had been pulled into the sanctuary of Dr Lis’s soft, thick tail. Its snowy tuft caressed your flushed, magenta cheek with rhythmic gentleness, while his lean yet strong arms cradled you into a warm, living cocoon.

The Foxian teacher leaned down, his chest vibrating as he let out a mysterious, low purr against your temple. The sound carried a strange, buzzing frequency that resonated through your rami, acting as a natural sedative that calmed your frantic heart and left you drifting in a state of absolute, sheltered peace.

Dr Lis' purr vibrated against your skin one last time before his voice returned to that professional, silken tone you knew so well. He pulled back just enough to look into your hazy, magenta eyes, a playful yet dominant glint in his own.

"Now, my dear mothling student... did I give you a sufficient lesson about the Kitsune’s reproduction?"

Your liquified, insectile brain couldn’t begin to form a coherent thought, but the surge of safety and happiness was so overwhelming that you simply gave him a wide, drunken smile of approval. Your antennae, once rigid with overstimulation, now drooped and brushed gently against the Foxian’s strong arms in a sweet, rhythmic touch of devotion. Dr Lis chuckled elegantly—a sound of pure, dark satisfaction—and nuzzled your temple one last time, marking the end of the most important lesson of your life.

"I will take that as a yes~" he purred, his voice thick with a dark, gratified warmth. He tightened his hold on your "cocoon" for just a moment longer before whispering against your skin: "I hope you will remember this lesson well, my darling student~ After all, we wouldn't want all this... extra credit... to go to waste~"

The light in the classroom was beginning to fade, stretching long shadows across the floor and signalling the quiet closing of this scene. As the room succumbed to the dark, the Foxian’s physical form blurred into the gloom, leaving only his violet eyes visible—burning with a steady, monitoring pink glow from afar. Even in the silence, you could feel his gaze, a final, glowing mark of the lesson that would never truly leave you.
