Zenless Zone Zero: "The Harem Theory (Advanced Studies)"

Summary:

Xavier Storm is a quiet, nerdy student at New Eridu University—barely 5'5", always buried in textbooks, and armed with mismatched eyes that seem to pierce through façades. But beneath the awkward hoodie and glasses lies something dangerous. Something… irresistible.

It started with Jane Doe, the flirtatious, whip-smart Rat Thiren who just wanted a little fun with her tutor. But what was supposed to be a tease turned into submission—her first fall. And she wouldn’t be the last.

As more of New Eridu’s most powerful, seductive, and dangerous women cross paths with Xavier, they discover the truth: beneath the awkward posture is a quiet storm they’ll never recover from.

A slow-burn, harem-style, erotic college AU filled with tension, flirtation-

How many “good girls” does it take to break the calmest nerd on campus?
Spoiler: none. He’s breaking them first.

Chapter 1: Chapter 1 (Lesson One: Obedience)

Notes:

Howdy, Howdy alright so let me explaining to do. This...this wasn't suppose to be a book!?! In fact it started out as a one-shot! A complete one and done!! But one of my best lawyer (my girl) decided to tempt me to continue with a bit of aftermath/aftercare for the care and it just spiral out of control!

So here we are with another long book but this time LEMON/SMUT mainly! Honestly not expecting my first main smut plot driven fic would be an Zenless Zone but here we go! To Help you all understand a bit better.

If you have READ any LONG 18+ hentai comic or mainly 'THOSE' MAWAHA then you understand as you reading this! How this going to go or the main driving factor. So I will put this here as a Disclaimer

DISCLAIMER: This is a SMUT/LEMON driven book, where the main focus is 18+ OC x Zenless Zone Zero characters is a Modern/College AU. There is a plot but it heavy lemon base, if that isn't what you came for PLEASE LEAVE this won't as deep as you might have hope. DO NOT TAKE THIS FANFIC SERIOUSLY at the end of the day this is nothing more to be fun and the author to be horny. Please be respectful and if this isn't your cup of tea, there are plenty other good Zenless Smut fic's out there. Thank you.

Beside that;

Enjoy.

Chapter Text

The study room smelled faintly of old coffee and sun-warmed paper, a quiet corner of campus that felt suspended in time. Dusty shelves lined the walls, their books untouched for years, while a soft amber light from the overhead fixture pooled over the cluttered table. Flashcards were scattered among annotated printouts and a single half-empty mug — steam still curling from the rim.

At the center of it all sat Xavier.

Back straight. Glasses slipped slightly down the bridge of his nose. Sleeves rolled neatly to his elbows. A pencil tucked behind one ear. His mismatched eyes — one a crimson, the other a richer, verdant orange — flicked between his tablet and the scribbled notes beside him. He tapped something onto the screen, lips parting in a soft murmur only the silence could hear.

He didn’t expect company. He didn’t want company.

Not usually.

Then the door opened with a click, and everything changed.

Xavier looked up — and nearly dropped his stylus.

Jane Doe leaned against the doorway like she owned the room. Her expression was the same confident smirk she always wore, but tonight, there was something else behind it — something daring. The hem of her uniform skirt hovered far too high on her thighs, swaying just enough to tempt. Her blazer was worn loose, the zipper halfway down, revealing the plunging neckline of a dark, fitted tank top beneath.

“Hey, genius,” she said casually, twirling her lanyard around one finger like it was a weapon.

Xavier’s throat tightened. “H-Hey… didn’t think you’d be here so early.”

“I couldn’t wait,” she replied, pushing off the doorframe and sauntering toward him, each step deliberate. Her hips moved in rhythm, a sway that seemed far too practiced to be anything but intentional. “Guess what?”

He blinked, shoulders tensing as she got closer. “Uh… you finally read that supplemental chapter I sent you?”

She laughed — a husky, teasing sound — and dropped into the seat beside him. Too close. Her knee brushed his. “Wrong again. I aced the test.”

She slid a paper onto the table with a satisfying slap — bold, red ink scrawled at the top.

100%.

Xavier’s eyes widened behind his glasses. “Wait… you’re serious?”

Jane leaned in, chin resting in her hand, her gaze fixed on him with shameless amusement. “Dead serious. Looks like your tutoring sessions paid off.” Her voice dipped lower, more intimate. “Or maybe I just really like the way you explain things.”

He flushed, ears burning. His eyes darted to her lips before quickly returning to the page. “I—I mean, I just helped outline the core concepts. You… did the real work.”

“Mm. Don’t be modest.” She trailed one finger along the paper’s edge, then up to his wrist. “You saved my grade. Maybe even my semester. That deserves a reward.”

Xavier tried to form a reply, but the words stuck somewhere in his throat.

Jane stood up before he could think of anything.

SlowlyDeliberately.

She circled the table like a predator eyeing her next move — then stopped in front of his chair. One brow arched. She was still smiling. Mischievous. Knowing.

“Well?” she asked. Her voice softened, dipped into something silkier. “Aren’t you gonna congratulate me properly?”

Xavier tilted his head up to look at her — and that was his mistake.

Because the moment their eyes met — hers glowing with anticipation, his wide with barely-contained tension — she moved.

She dropped to her knees.

Right between his legs.

Still grinning.

“You gonna give me an A…” she murmured, fingers sliding up his thighs, slow and featherlight, “...or an O?”

Xavier forgot how to breathe.

“J-Jane—” Xavier’s voice cracked as her fingers drifted across the inside of his thigh, a featherlight touch that moved like sin in slow motion. She traced the fabric of his pants with the easy confidence of someone who’d done this before—though with her, it was always impossible to tell where the teasing stopped, and the truth began.

She looked up at him from her knees, lashes dark and low, amber eyes glinting with mischief. Her grin was sharp enough to cut through steel. “Relax, nerd,” she purred, her voice softer now, intimate, coaxing. “I told you—I’m just saying thanks.”

Xavier’s mouth opened. Closed. His hands gripped the edge of his chair like it might anchor him, but Jane’s fingers kept climbing, brushing higher, teasing toward dangerous places.

“I-I don’t think this is how students usually—”

“Oh please,” she interrupted, voice velvet-slick. “You’re not just a tutor, Xave. You’re a damn academic miracle. You took me from scraping bottom to straight A’s in two weeks.” She gave his thigh a firmer squeeze, her hand hot through the fabric. “That deserves more than a gold star.”

Xavier made a soft, pitiful sound in his throat — somewhere between a laugh and a plea — as she leaned in and pressed a kiss just above his zipper. His breath caught. His knuckles turned white where they clutched the chair.

“And besides…” she added, her voice now a sultry whisper that buzzed right into his nerves, “you’re cute.”

That did it.

His entire face lit up like a siren — bright red across his cheeks, ears glowing, glasses fogging slightly as he looked down at her like he couldn’t believe this was real.

“M-Me? Cute?”

Jane’s grin widened — hungry now, edged with heat. “Don’t act like you don’t know,” she murmured. “You and your perfect little shirts, those mismatched eyes—” Her gaze lingered on his right eye, crimson like coals, then shifted to the left, a softer, burning orange. “—looking like trouble without even trying.” She leaned forward, her fingers already sliding up to his waistband. “And you’re packing something serious under all that shy-boy armor, huh?”

Xavier blinked. “Wait, what—”

The button popped. The zipper came down, slow as a tease. And then, with practiced ease, she slipped her fingers beneath the band of his briefs—

paused.

Her breath hitched.

“…Holy fuck,” she whispered, eyes suddenly wide with awe. “This… has been under those tucked-in polos? You’ve been walking around campus like this?”

She pulled his cock free with both hands, letting it rest in her palm—thick, hot, heavy. It throbbed once in her grip, and she stared at it like it was some sacred relic of an ancient god. “God damn,” she muttered, her thumb brushing across the flushed tip. “You could ruin someone with this…”

Xavier made a strangled noise as she started to stroke him, slow at first, fingers curling with just the proper pressure. His hips twitched. His breath stuttered.

“I—I didn’t think you were actually going to—”

“Too late to back out now,” she murmured, eyes half-lidded. Her grip grew firmer. “Not when you’ve got this monster sitting in your lap. And here I thought you were all brain, no bite.”

Whatever words he’d meant to say melted into the air as his hand lifted—tentative at first—then gently cradled the back of her head. Not rough. Not pushing. Just guiding.

Jane paused. Her breath caught again but for a different reason this time. “…Oh?”

Xavier’s mismatched eyes were lidded now, the red one glowing faintly in the low light. His voice, when it came, was deeper. “Show me how grateful you really are,” he said.

Jane’s pulse jumped. Her smile softened into something darker, more deliberate. “Yes, Professor,” she whispered, lips brushing the tip. Then she wrapped them around him.

WarmWetSlow.

She took him inch by inch, tongue swirling, mouth stretching to accommodate the size of him. Her cheeks hollowed as she sucked gently, building a rhythm.

Xavier groaned low, fingers threading through her hair — still not forcing, just guiding, giving her the pace but staying close. Above her, his breath was ragged, his body tense, muscles flexing under his rolled sleeves. His other hand gripped the chair’s arm, knuckles tight.

Jane moaned softly as she worked him deeper, the vibrations making him twitch in her mouth. She bobbed her head slowly, letting drool spill from her lips as she sucked him in again, deeper this time.

“God…” he muttered his tone somewhere between stunned and reverent.

Jane just smiled around his cock.

She loved seeing Xavier like this—. Falling apart, inch by inch. And yet, she had a feeling…

He hadn’t even begun to show her how far he could push back.

Jane’s lips stretched wide around the thick weight of him, the heat of Xavier’s cock pulsing against her tongue as she dragged slow, deliberate licks along the underside. Each pass was practiced but hungry, her tongue curling to map out every vein, every twitch, every subtle reaction he gave. At first, her eyes glimmered with that same playful arrogance — pleased at the way his breath hitched, how his thighs tensed ever so slightly under her fingers. She knew what she was doing. She thought she had the upper hand.

But then—

His hand moved. Fingers slipped gently into her hair, slow and careful. Not yanking, not demanding. Guiding. And something about that shift — the quiet control of it — made Jane’s pulse skip.

“Just like that…” Xavier murmured, his voice low and rough. His thumb traced along her cheek and brushed her jaw, so tender it almost felt reverent. Jane paused for a split second, surprised by how steady his tone was. Then—

“Good girl…” The words hit like a shot to the spine.

Her breath caught around him — and then she moaned. A low, wet sound vibrated around his cock as she eased him deeper, her pride melting beneath the warmth spreading in her chest. She didn’t expect the praise to hit that hard. But it did.

God, it did.

Xavier’s fingers tightened gently in her hair as she sank farther down, his mismatched eyes locked on her face. Red and orange, intense and unreadable. He watched every little twitch, every flutter of her lashes as she worked to take more of him. His hips shifted just slightly, a soft grind forward, his voice curling down her spine like silk-wrapped steel.

“You’re doing so well…” he whispered, thumb now stroking behind her ear. “Taking me so good…”

Jane whimpered again — small, needy — and her hands gripped his thighs tighter, anchoring herself as she started to bob her head, slow and smooth, keeping perfect pace with the subtle pulls of his fingers. The rhythm wasn’t hers anymore. Not fully. It belonged to him now. And that realization sent a rush of heat down between her thighs.

“Don’t stop now,” he breathed, voice firmer, more sure. Another light pull, another inch. “Just a little more…” His praise was like a leash she wanted to tug tighter.

“Such a good girl for me…”

Jane’s eyes fluttered. Her brows furrowed slightly. The smugness from earlier had faded into something else — something needier, deeper. She wanted to impress him. She wanted to hear more of that voice. That tone. She wanted to be the reason his control started to crack.

She adjusted her angle and slid farther down, her throat beginning to stretch. Her lips sealed tighter around him as spit dripped from her chin, coating his shaft as she took him deeper still. Her lashes fluttered, cheeks flushing, lungs working overtime through her nose.

Xavier groaned above her, the sound dark and heavy. His head tilted back, jaw flexing as he felt her throat begin to tighten around him. “Fuck… that’s it, Jane…”

His hips began to move on their own — not hard, just enough to meet her motion, to push a little farther, to feel more of her. The soft, wet sounds of her mouth filled the room now, mingled with the faint, guttural noises he let slip.

He still hadn’t lost control.

Not yet.

But Jane was getting there.

She was panting now, tears prickling at the corners of her eyes from the stretch and the heat and the praise — so much praise — spilling from his lips in that smooth, commanding voice. And all Xavier did was keep guiding her.

GentleSteadyDevastating.

Jane had found her rhythm — but it was his rhythm. And she was falling under it.

Jane's fingers dug into Xavier's thighs, knuckles white as she bobbed on his cock with increasing rhythm, each movement deeper than the last. Saliva clung to her lips and dripped down her chin, strings of it glistening under the study room lights. Her muffled moans vibrated along his shaft, trembling with desperate need—like she was trying to earn every word of praise he gave her.

And he gave them, low and fervent. "Good girl…"

"Just like that…"

"You feel so fucking perfect."

Those words were everything to her. They lit her up and drove her. She chased them like air, like a girl starved for approval, addicted to every dark syllable he fed her. So focused was she on pleasing him—on milking each groaned compliment—that she barely noticed the shift in his grip on her hair.

It tightened. His fingers curled at the base of her skull, steadying her, and then, without a word, Xavier moved.

In one fluid motion, he stood, towering over her, his cock never slipping from her lips. Jane gasped, but the sound was swallowed instantly by the thick length stretching her jaw. Her wide eyes flicked upward, dazed and glistening, as she instinctively planted her palms against his thighs to steady herself.

She didn't even get a chance to adjust.

He angled his hips down—and drove himself forward.

Hard.

His cock slammed down her throat, his pelvis mashing against her nose as his balls slapped her chin with a slick, devastating sound. Her whole body flinched, a sharp gag catching in her throat, but she didn't retreat. Couldn't. Her eyes flew wider, glassy with shock, but there was no escape—only the weight of him, buried deep, and the harsh grip in her hair holding her in place.

Xavier groaned low, his free hand sliding down to her throat, fingers splayed over the bulge of his cock inside her neck. He pressed, slow and possessive, thumb brushing where her skin stretched tight around him.

"Fuck…" he breathed. "Look at you… taking it all…"

Tears pricked at the corners of her eyes, but she refused to pull away. Even with her throat clenching involuntarily, even with every breath stolen from her, Jane knelt, jaw stretched, throat full.

And Xavier started to move.

Slow thrusts at first—short, controlled, each one deliberate. Then faster. Rougher. He fucked her mouth from above, using her like she was made for this, as she existed solely to please him. Her moans became soft, frantic vibrations around his cock, each one laced with desperation and unrelenting want.

SlapSlapSlap.

His balls struck her chin again and again, loud in the silence. Her throat clenched with every thrust, slick sounds of spit and skin filling the room. She was a mess—mascara streaked, lips stretched, drool dripping freely down her chest.

"You wanted to tease?" Xavier growled, voice rough as gravel. His palm still pressed against her throat, feeling himself slide deeper. "Now you're gonna worship every fucking inch…"

Her fingers clawed at his thighs—not to push him away, but to hold on, to ground herself. Her body trembled beneath the relentless pace, but she didn't stop. She wanted this. Needed it.

He held her there, hips snapping forward in brutal rhythm, hand locked in her hair, the other stroking her throat like it was the most precious thing he'd ever claimed.

Wetbrutalobscene.

Her moans broke around him—needy, choked, raw. Every thrust pushed her further, every second another crack in the polished, teasing girl she'd been before. Now, she was his. On her knees, broken open and ruined by the nerd, she thought she could fluster.

"Fucking perfect," he growled, eyes burning. "You look so good like this… drooling on my cock…"

She was past thought, past pride, spit bubbling from her lips, tears streaking her cheeks as he kept going, driving into her with no mercy. Her jaw ached. Her throat burned. Her brain barely processed the pace—but her body stayed locked in place, moaning around him like it was the only thing keeping her together.

"You wanted to walk around like I wouldn't snap someday?" Xavier snarled, slamming forward again. "That I'd just sit there, pretending not to see what you were doing every time you leaned over in my damn shirt?"

He held her deep, cock buried down her throat as her entire body shuddered. Her moan came out like a garbled cry, muffled and soaked with spit, throat bulging obscenely beneath his hand.

"I held back for weeks, Jane…" he hissed, thrusting again, now with tight, punishing force. "You have no idea what I've imagined doing to you in this fucking room…"

She sobbed around him, her body trembling violently, her mouth never leaving his cock, even as it pulsed thick and heavy between her lips. She was gone.

And he wasn't even close to done.

Xavier groaned deep in his chest, voice thick and strained as he thrust one last time—grinding against her face, cock lodged deep down her throat. His fingers tightened in her hair. His hips jolted once, then again.

And then—

He came.

Hard.

His entire body stiffened as his cock twitched deep in her throat, thick spurts of cum shooting straight down as he grunted through clenched teeth. Jane’s eyes flew wide as she felt the warmth flood her throat, thick and heavy and impossible to stop. She swallowed instinctively, her throat constricting around him with every pulse, her entire body trembling from the overwhelming intensity.

She couldn’t breathe—not really. Her nose was clogged with spit and tears, and her throat was stretched so tight it burned. But she still didn’t pull away. She held onto his thighs, nails digging into his skin, body shuddering with the effort to stay upright, to take every drop.

By the time he finally eased back, slowly withdrawing from her mouth with a wet pop, Jane collapsed forward onto her hands, coughing softly, drool and cum spilling from her lips in sticky, glistening strands. She was a mess—completely and utterly ruined.

Her breath came in shallow gasps, lashes wet with tears, throat raw and aching most deliciously. Strands of spit hung between her lips and his cock, pooling on the floor below. She blinked up at him with glassy eyes, cheeks flushed a bright, feverish red, makeup streaked and smudged in chaotic lines across her face.

And then—gently, almost tenderly—Xavier reached down and stroked her cheek with the back of his fingers, his thumb brushing just beneath her eye. “…You really are a good girl.”

The words shattered something inside her.

Jane coughed again, still breathless, still glowing from the praise. Her lips—slick and red—quirked up into a trembling smirk as she leaned back on her heels, trying to catch her breath, trying to recover some semblance of composure. Her chest rose and fell in sharp little bursts. Her mascara was a disaster. Her throat was on fire. And she had never felt so turned on in her entire fucking life.

She swiped at her mouth with the back of her hand and let out a breathless, shaky laugh. “...Jesus fuck, Xavier.” Her voice cracked on the last syllable.

She looked up at him again, still looming over her, his expression unreadable—eyes dark, breathing controlled, as if he hadn’t just face-fucked her to tears. His cock was still thick, still heavy and flushed, glistening with her spit and his release. And she couldn’t stop staring at it.

“You’ve been walking around like some shy-ass honor student,” she rasped, voice rough and hoarse. “And now you’re face-fucking me like you’ve got a damn vendetta—what the hell...?”

She trailed off when he moved.

No words. No warning. He reached up and slowly removed his glasses.

Click.

The sound was quiet, but it echoed in her ears like the snap of a lock being undone. Her mouth parted slightly, heart thudding. And then—he began to unbutton his shirt.

One button….Two….Three…

The fabric parted to reveal smooth, toned muscle—his torso lean but cut, every line sculpted and tight beneath the soft cotton. His chest rose slowly with every breath, and Jane’s eyes followed the motion like she was hypnotized. His arms flexed from restraint and carried subtle power—like a man who spent time in control, even if he never showed it.

“The fuck…” she whispered, throat still raw. “When the hell were you hiding all that?”

Xavier didn’t answer. He just let the shirt fall from his shoulders, tossed it aside, and set his glasses down on the nearby desk like they belonged to a different person entirely. The nerdy boy with the quiet voice and nervous blush?

Gone.

The man before her now was something else entirely—sharp, silent, and terrifyingly in control.

And his cock—God, his cock—was still hard. Still pulsing. Still towering in front of her flushed ruined face.

Jane blinked, lips still parted, her voice barely audible. “...Wait. Did you—” She cut herself off, eyes narrowing in disbelief. “Did you get harder?”

Again, no response. He didn’t need one.

Instead, Xavier stepped forward, grabbed her by the waist with both hands and lifted her like she weighed nothing.

“W-Whoa, hold on—!” she yelped, arms flailing slightly.

He set her down atop the table, the wood warm from the heat of their earlier study session, her thighs falling open instinctively as he stepped between them. Her skirt hiked up around her hips, panties soaked and clinging to her, thighs slick with arousal.

She wasn’t ready. She wasn’t prepared. And yet her body screamed for more.

“You don’t get to look at me like that,” Xavier murmured, voice low, close to her ear now. “Tease me. Strut in here the way you did and expect me not to snap.”

His hands roamed—slowly, reverently—down her sides, fingers curling beneath the hem of her ruined blouse. He dragged it up over her torso, baring her chest inch by inch until she was stripped bare before him, panties the only thing separating her from complete exposure.

Jane swallowed hard, eyes wide. “I didn’t think—”

“Exactly,” he cut in, voice darker now. “You didn’t think.”

He grabbed her hips and pulled her forward until her ass reached the edge of the desk until the soaked fabric of her panties brushed the head of his cock. Her legs wrapped around his waist without thinking, heels digging into his lower back.

“You wanted to play games?” he whispered, tilting his head. “Then playtime’s over.”

He reached between them and dragged his cock slowly up the soaked crotch of her panties, the thick head rubbing between her folds through the fabric, pressing against her clit in slow, purposeful strokes.

Jane gasped—legs trembling, head falling back. “Oh f-fuck—”

“Shh…” He leaned in, lips brushing hers. “Be a good girl again. Just like before.”

She whimpered, hips rolling up against him as he rubbed harder, the pressure unbearable now.

“I’ll ruin you properly this time,” he whispered, voice like velvet over steel. “And you’re going to thank me for it.”

“I—Xavier—wait, just give me a second—”

But she didn’t get one. He stepped forward, his grip tightening around her hips—and in a single, devastating motion, he slammed into her.

“F-Fuck!” Jane’s scream tore out of her throat as her back snapped off the table, the sheer force of him stealing every ounce of air from her lungs. Her legs flew around his waist, thighs trembling, heels digging in on instinct as her hands shot over her head, gripping the edge of the desk like it was the only thing keeping her anchored to reality.

No pause. No easing in. No moment to breathe.

He just claimed her.

Thick, hot, and impossibly deep—he filled her in one smooth thrust, bottoming out so hard she saw stars. Her mouth fell open, eyes wide and glassy, brain stuttering on blank static as the whole stretch of him registered like a shockwave through her body.

He didn’t slow. Didn’t let her adjust.

He pulled out just far enough to tease—then drove back in with a brutal snap of his hips that sent the table groaning beneath them.

Jane gasped, voice splintering into a ragged moan. Her body jolted under him, breasts bouncing with force, her soaked pussy sucking him back in with a sound so wet and obscene it made her thighs twitch.

He was everywhere—inside her, over her, around her. And she was helpless.

Her hands scrabbled at the desk. Her eyes rolled back. Her whole body tightened as her core tried to process the relentless, perfect rhythm he was building.

“X-Xavier—!” she cried, the syllables slurred. “Too—ah—too fucking deep—!” But he didn’t stop.

His hips snapped forward again, cock dragging hard against her walls, hitting something sharp and explosive deep inside her.

Her breath hitched. Her head rolled back. She was already close. Too close. It wasn’t fair. He’d caught her off guard, turned her inside out with just a few strokes, and now her climax was coiling low in her belly, wild and unstable.

The room spun. The lights blurred.

The wet slap of their bodies collided with the sound of her ragged moans, her thighs trembling around his waist as he rammed into her with brutal, precise control.

Each thrust was another detonation, each movement tore a new cry from her lips.

She couldn’t hold it together. Couldn’t think. Her whole world had narrowed to the heat between her legs and the sound of his breath—low, rough, controlled.

“Xavier—please—” she gasped, not even sure what she was begging for. “I—I can’t—!”

“Yes, you can.” His voice was low, hoarse—dripping with dark satisfaction. “You teased me for weeks, Jane. You knew exactly what you were doing.”

Her nails bit into his shoulders. Her voice caught in her throat.

Every thrust jolted her body like she was being pulled apart and put back together again. Sweat beaded between her breasts. Her shirt had long since ridden up around her waist, her chest bared, nipples sensitive and bouncing with every slam of his hips.

“You walked around like I wouldn’t snap.” He leaned closer, mouth brushing her ear as he whispered, “But you wanted me to. Didn’t you?”

She sobbed—eyes squeezed shut, too overwhelmed to answer.

He kept going.

His cock dragged along her walls; each thrust striking that same raw, unbearable spot inside her. Her pussy clenched around him, greedy and fluttering, already fluttering from the edges of release.

“You feel that?” he growled again. “Every time I drive into you?”

She nodded frantically, tears brimming in her eyes, mouth open in a silent cry as another thrust knocked the air from her lungs.

“I’m gonna make sure you never forget what I do to you.” He punctuated the promise with another savage thrust, and her orgasm snapped like a whipcrack through her body.

Jane screamed.

Her legs locked tight around him, thighs quivering as her pussy clamped down in fluttering waves, milking his cock. Her back arched off the desk, breasts bouncing as every nerve in her body lit up and burned from the inside out.

She couldn’t breathe. Couldn’t see. All she could do was feel.

Xavier didn’t stop.

He fucked her through it—through the shaking, the twitching, the helpless sobs spilling from her throat. Her body trembled beneath him, overstimulated, soaked. Her hair stuck to her cheeks, sweat dripping from her neck down to the small of her back.

She whimpered his name. Over and over. Like it was a lifeline. Like it was the only word she had left. And still—he didn’t stop.

His grip on her hips was bruising now, but she didn’t care. Her fingernails clawed across his back, searching for something to hold onto—anything to ground her. But Xavier?

He was relentless.

His eyes—those mismatched, molten eyes—were locked on her face, watching her come undone again and again. There was nothing shy or soft about him now. No glasses. No hesitation. Just focus. Hunger. Control.

Her body tried to flinch away, muscles twitching from overstimulation, but he only pulled her closer—kept her flush against him, kept pounding into her as he owned her.

Because, at that moment, he did.

“F-Fuck—” he growled, hips slamming forward harder now. “You’re so fucking tight…” She could feel it—the throb of his cock inside her, the heat building, the way his abs flexed as he fought to keep control. His breath was ragged, his voice cracking.

And then—without warning—he reached between them, found her clit, and pressed.

Jane broke.

Her second orgasm ripped through her with no warning—violent and full-body. She wailed, her pussy spasming uncontrollably around him, walls locking down like a vice as her vision blurred and her thighs clamped around his waist with crushing force.

Her head rolled back, eyes wide and unseeing, her mouth open in a choked cry. The world went white. She convulsed under him, sobbing, twitching, soaking, her juices spilling down her thighs and over his cock with each deep, dragging thrust.

Xavier groaned—deep and guttural—fucking her through it like a machine, never giving her a moment to come down. Her body jolted with every movement, the desk beneath them shaking with the force.

And all she could do was cling to him, fingers clawing at his back, legs trembling, Mouth panting open with every breathless moan.

He slammed into her again, grinding hard, and her back arched one more time—body locking up, another orgasm threatening to spiral without end. She was past thinking. Past words. Her brain had melted, and her mouth could only moan, whimper, sob. And through it all—

Xavier’s rhythm never faltered.

If anything, he was fucking her harder now.

His jaw was clenched tight, breath hot and ragged, the muscles in his arms flexing with each thrust. Sweat ran down his chest in thin rivulets, dripping onto her flushed skin, mixing with hers in a slick, intoxicating heat. His grip shifted, hands gliding down to her waist, fingers digging into her hips like he couldn't bear to let go.

Jane moaned louder—louder than she had before—her cries dissolving into ragged, breathless sobs. Her eyes fluttered open and shut in helpless rhythm, every exhale broken by the slap of her back against the desk. She couldn't form full words anymore—just whimpers, gasps, and choked syllables. She was floating, burning, unraveling completely under him.

Then—

He lifted her. Not all of her. It's just the lower half.

Her ass lifted off the table as he adjusted his stance, angling her hips upward in one fluid motion. Her legs spread wider in the air, dangling slightly before hooking around his waist again. She could feel everything—more of him, deeper than before. The position was devastating. Her slick entrance opened to him perfectly, her body tilted just right, completely exposed and helpless in his grip.

And Xavier slammed into her from above like he'd been holding back the entire time.

The sound was thunder—sharp, wet, filthy echoes of skin meeting skin, filling the room with every punishing snap of his hips. The desk creaked beneath them, its legs shifting slightly under the force. Jane's fingers scrambled against the wood above her head, nails clawing uselessly as her body arched up into him, suspended by his hold and his cock and absolutely nothing else.

Her chest bounced with every brutal impact. Her nipples, glistening with sweat, dragged softly against the air. Her stomach tensed, then clenched, muscles twitching as her orgasm began to build again, hotter and harder than before.

"F-Fuck—fuck—" she sobbed, her voice cracking apart into raw syllables. She was gone. Gone. Brain fried. Muscles locked. And Xavier? He saw it.

He knew what her trembling thighs meant. Knew what the broken pitch in her moans signaled. Knew exactly where she was in that fragile moment before total release. So he leaned in close, mouth brushing against her ear, voice like gravel and smoke.

"Cum for me, Jane…" That was all it took.

One more thrust. Her body seized.

Jane shattered with a scream—loud, hoarse, and torn from the very center of her being. Her back arched violently, toes curling, her thighs clenching tight around his hips. Her walls clamped down on him in powerful, pulsing waves, each one stronger than the last. She jerked beneath him, her whole body trembling as she came so hard it stole her breath and every coherent thought along with it.

"Ah—fuh—Xav—!" Her tongue lolled from her mouth as she screamed again, eyes rolling up, muscles twitching out of control.

It was too much—too intense. The kind of orgasm that left her vision fuzzy and her limbs numb. And then—

He came.

With a ragged groan, Xavier slammed deepall the way—and stayed there. His arms locked around her hips, and his abs flexed as he held her against him. She felt the moment it hit him—the way his body stiffened, the sharp inhale between his teeth.

Then he pulsed.

Thickhot spurts flooded her, heat rushing deep inside her twitching walls. She could feel it, every rope of cum pouring into her, filling her, claiming her from the inside. Her pussy fluttered around him, milking him for every last drop as her climax rolled into smaller, uncontrollable aftershocks.

Her breath caught, Her eyes fluttered, Her whole world went white.

Her body collapsed backward onto the desk, arms limp, chest heaving in ragged bursts. Her legs dangled over the edge, twitching in the aftermath. Her mind was blank—totally, deliciously blank—as her muscles gave up completely. Her tongue was still hanging out slightly, lips parted, drool glistening at the corner of her mouth.

Xavier didn't move right away, he just breathed.

Chest rising and falling in slow, uneven pulls. His arms trembled slightly from holding her up. He was still buried inside her—deep, warm, pulsing. His hands gripped her thighs, thumbs brushing her skin, not possessive now, but reverent.

Jane was wrecked. A soaked, twitching mess of sweat, cum, and breathless, shattered satisfaction. Her hair stuck to her face. Her makeup was gone. Her entire body was trembling, her thighs still quivering from the intensity of her orgasm.

She couldn't speak. Couldn't think.

And then—she felt him move. Her body jolted slightly, nerves raw, overstimulated.

She blinked slowly, dazed, as Xavier finally pulled out. The sensation made her gasp—wet and thick, a slow, sticky slide as he withdrew, leaving her aching and empty. Her hips dropped to the desk with a soft thud, legs too weak to hold themselves up.

For half a second, she thought it was over.

‘Oh, thank god’, she thought, her breath coming in ragged little shudders. Maybe now I can—

Flip .

She yelped—more a squeak than a scream—as Xavier's hands returned to her hips, grabbing her with renewed force and turning her over in one swift, firm motion.

Her chest met the desk, her cheek pressed to the wood, and her hair spilled across her face. Her legs dangled off the edge, thighs parted slightly. She was still soaked. Still twitching. Her ass—red, flushed, glistening with cum—was now fully exposed to the air. Xavier stepped in behind her again.

And Jane's breath hitched.

“W-wait—Xavier—” Jane gasped, finally finding her voice for half a second.

But he didn’t wait, didn’t ask, didn’t hesitate.

She felt it—the heat of him, the pressure—stroking against her soaked entrance as he aligned himself again. Her heart slammed against her ribs, panic, and pleasure indistinguishable in the white-noise haze flooding her brain.

“No—wait—I can’t—” And then he slammed into her.

“F-FUCK!” she shrieked, her entire body jolting forward as his cock buried itself back inside her with unrelenting force. The sound of his hips crashing into her was immediate, obscene—his balls smacking against her overstimulated clit with a sharp, wet clap that made her cry out again. Her hands splayed against the desk, trying to find leverage, trying to breathe.

She failed on both fronts.

Her voice shattered into a hoarse, choked gasp as Xavier began pounding her; no mercy, no restraint. Rougher. Faster. His thrusts were a storm—feral and animalistic, shaking the table beneath them as he fucked her with the kind of desperation that felt like punishment and worship all at once.

Her ass clapped with every impact, cheeks jiggling wildly, the sound of wet, brutal collisions filling the room like thunder. She couldn’t think. Couldn’t speak. Her mouth was open, but no words came—only air. Wheezes. Sharp, sobbing little moans that broke off mid-breath.

Her body was done.

Ruined.

But Xavier wasn’t, his fingers dug into her hips tighter, dragging her back onto his cock with each punishing thrust, splitting her open over and over like she wasn’t already wrecked. Her tail betrayed her—twitching wildly, then wrapping around his wrist as if her body was begging for him, clinging to him, even when her thoughts couldn’t keep up.

Her forehead pressed to the desk. Her hands curled into fists.

‘Fuck… fuck… this nerd is going—’

He slammed into her again, hard enough to punch a sob from her throat.

‘—to fucking break me.’

The room was chaos now—an orchestra of slick, wet slaps, sharp gasps, and the relentless creaking of the table legs beneath their bodies. Jane’s voice was gone, reduced to broken sobs and guttural moans that echoed between breathless, twitching gasps. Her pussy was red, swollen, soaked. Her ass bounced violently from the sheer pace Xavier was drilling into her with—flesh clapping, legs wobbling, slick dripping down her inner thighs.

He leaned over her, breath hot against her ear. His voice was lower now—raw and feral, edged with the restraint he no longer cared to maintain.

“This…” Slam “This is for every time you bent over in my hoodie…” Slam “…every time you leaned in and whispered those filthy little lines while I was just trying to focus…” SLAM “…for every fucking time you said I was cute like I wouldn’t pin you down and ruin you…”

She moaned—high, desperate, brain short-circuiting—because this was so much worse than anything she’d imagined. Or better. She didn’t know anymore.

His pace got faster. Harder. The rhythm of his hips reached a fever pitch—plap plap plap—each impact deeper than the last, angled to devastate. Her vision blurred. Her toes curled. Her body braced, but it wasn’t enough.

“You think I didn’t notice?” Xavier snarled, voice cracking as he rammed into her again. “Think I didn’t jerk off to the sound of your voice moaning through my head every night after study sessions?”

She tried to scream into the desk—a high, broken wail—but it barely made it out. Her lungs weren’t working. Her mind wasn’t working.

“Think I didn’t imagine fucking you stupid just like this—over and over—until you couldn’t fucking walk?”

And then—she clenched.

Hard.

Her orgasm detonated like lightning in her core. She didn’t have time to warn him. Didn’t even get a word out. Her body just seized—thighs locking, back arching, pussy clamping around his cock with a wet, fluttering squeeze that made her see stars.

“AH—!”

Her voice cracked into a ragged, throat-torn scream, her mouth frozen open in a silent, shocked expression as she trembled violently in his grip. Her body jerked and twitched as wave after wave of release surged through her. Her thighs gave out. Her knees buckled. Her arms collapsed.

Her slick squirted down her thighs—hot, wet, gushing as her walls fluttered around him, pulsing like they were begging him not to stop.

And Xavier? He groaned—deep and low—but he didn’t stop, didn’t slow. Her orgasm was just his signal to fuck her harder.

She was gone.

Her face was mashed to the desk, hair plastered to her cheeks, lips parted in a breathless, soundless cry. Her chest rose and fell in stuttered gasps, her entire body slick with sweat and overwhelmed by touch.

Her pussy clenched again and again—overstimulated and dripping—still trying to grip him, suck him back in every time he pulled out. It was reflex now. Need. And Xavier? He wasn’t done.

His thrusts stayed sharp and brutal, measured only by the primal need carved into every line of his body. His grip stayed locked to her hips. His cock drove back into her with a punishing rhythm—full length, full stretch—until the only thing she could do was lie there and take it.

And she did.

Tears slid from the corners of her eyes. Her tail spasmed behind her, curling with each thrust. Her body flinched from overstimulation, but she couldn’t move away. She didn’t want to move away.

Because the truth was undeniable now. She’d teased the wrong boy. And now? Now she was paying for it—moaning, twitching, breaking on his cock like he was the only one who’d ever known what to do with her.

If anything, he was fucking her harder.

His grunts came sharp through gritted teeth, his breath ragged, face twisted with effort as he gave her everything he had. His hips slammed into her with a punishing rhythm, the wet smack of skin on skin echoing through the ruined silence of the study room like a war drum. His hands never loosened—wrapped around her hips with bruising force, dragging her back onto his cock with every raw, furious thrust. Like her body owed him. Like her moans were confessions. Like every inch he sank into her, it was earned.

“Look at you…” he snarled, breath hot and broken. “Fucking ruined… and still taking it…”

Jane could barely make a sound. Her voice had collapsed into nothing—just weak, ragged sobs and broken, breathless gasps. Her throat was raw. Her body trembled with overstimulation. Her ass clapped wildly with every impact, cheeks bouncing, rippling with each brutal slam of his hips. Every thrust forced more slick to spray between her thighs, her juices coating his cock, the desk, and the floor.

She was soaked, RuinedDestroyed.

And yet, her tail betrayed her again—whipping and curling before it wrapped itself tight around his forearm, clinging like it didn’t want him to stop. Like it was the only part of her that still knew what she needed. Not rest. No mercy. But more.

Xavier’s eyes burned. His mismatched gaze—red and orange—never left her. He stared down at her with something primal, possessive, something past hunger. She was red. Shaking. Wrecked. Her legs hung limp, knees weak, her body twitching beneath him like she’d been dismantled and rebuilt by his hands alone.

And still—she was clenching around him, still begging.

“You think I’m done?” he hissed, voice guttural, animal. “You think I’m gonna stop before I fucking fill you up?

She tried to respond. A high, broken moan ripped from her throat, involuntary and desperate, her body sagging under the weight of her own need. She couldn’t form words. Couldn’t even beg. She just opened her mouth and hoped he’d read it in her eyes.

He did. One hand slid down, fingers hooking under her thigh. He lifted her leg just enough—angling her hips upward—and then slammed into her.

Balls deep.

Her whole body jolted, her spine arched. Her mouth fell open in a soundless scream as her pussy clenched hard around him, deeper than before, fuller, every thrust angled to break her apart from the inside. The sound of their bodies colliding filled the room—raw, slick, filthy.

And he kept thrusting. HarderFaster.

Every movement shoved her farther into the desk, her breasts dragging against the cool wood, her nails leaving faint, useless scratch marks. Her vision blurred. Her tail writhed. Her thighs were slick and trembling, coated in their combined mess.

Then—his breath hitched. His hips lost their rhythm and turned sharp. Urgent. Wild.

“Fuck—fuck, Jane—” he gasped.

His grip tightened like a vice, dragging her into him one last time. He slammed forward—deep, so deep—and held.

His whole body locked. And then he came.

A guttural, raw groan ripped from him as his cock twitched violently inside her, jerking with each pulse as he emptied himself. Thick ropes of cum poured into her, coating her insides in heat, her pussy milking every drop as her walls fluttered around him uncontrollably. She felt it.

All of it.

The way he pulsed—the heat of it inside her. The mess of it leaked the moment he started to soften. Her legs gave out again, dangling uselessly off the edge of the desk, thighs trembling as her body twitched beneath him. Her mouth hung open. Her tongue slipped from between her lips, drool joining the sweat already dripping from her chin.

Eyes glazed, Mind blank.

Gone. Completely. Utterly. Fucked.

Xavier collapsed over her, his cock still buried deep, breath ragged and uneven as he leaned his chest to her back. Sweat dripped from his brow onto her shoulder, mingling with hers, both of them coated in heat, in effort, in each other.

His hands trembled slightly—still locked to her hips, still holding. Still owning.

“You’re mine now…” he breathed, voice low, guttural. His lips hovered near her ear. “Every last fucking inch of you…”

And Jane? She couldn’t say a damn word. She moaned—soft, wrecked, barely audible—and maybe she nodded. Or maybe her body just twitched in response, nothing left in her but muscle memory and instinct.

Because she couldn’t think anymore, couldn’t speak, couldn’t move.

The study room was silent now, save for their breathing. The air was thick, humid with sweat and sex, heavy with the echo of everything that had just happened.

Her tail loosened from his wrist, and she fell limp.

Her fingers slipped off the desk, arms giving up entirely.

Xavier stayed inside her. Still full. Still hard enough to twitch. He didn’t move—not yet. His hips pressed gently against her ass like he wasn’t finished. Like he was still deciding whether round three would start now… or in a minute.

Jane didn’t care, she couldn’t care, she was ruined—and she liked it.

She had teased him for weeks, never realizing that beneath that quiet, nerdy exterior was something relentless. Something unshakable. Something that had waited—not because he was shy, but because he was calculating.

And now?

Now she knew, Xavier wasn’t just dominant. He was methodical.

And she? She’d walked willingly into the lion’s mouth—laughing, teasing, half-naked in his clothes. And now she was nothing but a mess. One that he had made.

And one he clearly wasn’t finished with.

The study room was quiet again.

Sort of.

The air still clung heavy with the scent of sweat, sex, and scorched dignity. The desk creaked ominously beneath Jane’s weight—like it had witnessed too much and wasn’t quite sure it would ever recover. But for the most part, calm had returned.

Jane lay draped across the abused furniture, legs still twitching faintly, her body completely boneless. A dazed, blissed-out smirk was frozen halfway across her lips as she blinked at the ceiling in silence.

“…Okay,” she finally breathed, voice rough but amused. “So… what the fuck was that?”

Xavier, nearby and trying very hard not to look directly at her naked body, fumbled with the last button on his shirt. His cheeks were still flushed, and his hands still shook slightly as he tucked himself back in and reached for his glasses.

“I… might’ve gotten carried away,” he murmured, slipping the lenses back on with a sheepish clearing of his throat. He still couldn’t meet her eyes.

Jane let out a short, breathy laugh and reached out to slap his thigh—though the hit landed with more of a flop than any force. “Carried away?” she echoed, still grinning. “Nerd, you rearranged my guts and melted my spine. I’m pretty sure I hit the astral plane somewhere between the second and third orgasm. I’m still waiting for my soul to download back into my body.”

That made him blush harder. He rubbed the back of his neck, suddenly looking like the Xavier she’d first met—quiet, awkward, adorably unsure of what to do with his hands.

Jane watched him for a beat, the corners of her lips curling up. Then she tried to sit up, propping herself onto one elbow—only to immediately flop back with a groan. “…Still can’t feel my legs.”

“Sorry,” Xavier said quickly, panic flashing across his face as he knelt beside her with a towel in hand. “Here, let me—”

She blinked as she realized what he was doing. “Wait… is that from the—”

“I ran and soaked it from the washroom,” he muttered, face red as he began gently dabbing at the sticky mess between her thighs with meticulous care.

Jane stared at him. Then she laughed.

A soft, breathless laugh that bubbled up as he wiped her down like she was a porcelain doll instead of the girl he’d just bent over and fucked into next week. “Oh my god,” she giggled, her hand brushing through his hair as he worked. “You’re back to being my sweet, flustered, overly-prepared tutor again. You’re adorable.”

He didn’t look up. “I’m still the guy who made you drool on your own desk.” Jane blinked.

Her face flushed. “Okay… fair. Point to the nerd.”

He chuckled awkwardly. “Thanks.”

She grinned. “Still cute though.”

That got him. He stilled—ears turning crimson, lips parting like he wanted to say something but couldn’t quite process how to respond. He stood there for a second, fidgeting, hovering… caught between crawling back into his shy shell or just disappearing into the carpet fibers altogether.

Then, without warning—

He stepped forward. Bent down. And scooped her into his arms. Bridal style.

Jane squeaked.

“W-wait! What are you—?!” she yelped, clutching his shirt as he lifted her like she weighed nothing.

“Carrying you,” he said, adjusting his grip without effort. “It’s my fault you can’t feel your legs, remember?”

Her eyes widened in stunned silence… then softened. “Oh.” Her hand slid gently across his chest, fingertips brushing the fabric over his heart as she looked up at him. Her expression turned quiet, warm. “You’re full of surprises today, Xavier.”

He began walking toward the hallway that led to his room, his gaze forward but his voice steady. “I’ve had time to think about them.”

Jane’s heart fluttered. She rested her cheek against his shoulder, her tail wrapping lazily around his back like it belonged there. Her smile was slow, genuine.

“…Quite a charming nerd you are.”

Xavier didn’t reply. But his ears were red again.

And when she leaned in to kiss his cheek—soft and slow, lips lingering just long enough to make him shiver—he smiled.

For real.
