WRAPPED IN SIN {18+}
AU (Professor!toji x fem!reader)
————————————————————————————
Toji Fushiguro was the kind of professor who made the entire lecture hall sit up straighter the second he walked in. Late thirties, broad-shouldered, scarred, and built like a man who’d spent more time throwing punches than grading papers.
His dark hair was always a little messy, his sharp green eyes half-lidded in perpetual boredom or disdain and his voice carried that low, gravelly drawl that sounded like he was constantly on the edge of telling everyone to fuck off. He didn’t smile. He didn’t joke. He was the no bullshit History professor who seemed like he’s seen war, death, and worse, and now he taught because the university paid him enough to not give a shit about anything else.
Everyone knew to stay on his good side. He was tolerable with most students gruff, direct, occasionally even fair. But not you.
You were a solid third-year, top of most of your classes, the kind of girl who turned in immaculate assignments and never caused trouble. Yet from day one, Professor Fushiguro had it out for you specifically.
He’d bark your name during lectures for the smallest thing posture, a question phrased “wrong,” even the way you took notes. Your essays came back covered in red ink and insultingly low grades despite being flawless. “This is garbage,” he’d growl, tossing the paper on your desk while the rest of the class stared. “Try harder, or drop my class.”
You didn’t understand it. You weren’t the only one who noticed. Whispers followed you… ‘What did you do to piss him off?’
The tension had been building for months. Late office hours one rainy Thursday evening were the breaking point.
You knocked on his door with your latest project clutched in your hands—twenty pages of meticulously researched material on feudal Japan that you knew was perfect. The rest of the building was empty. Thunder rumbled outside.
“Enter.”
You stepped inside. Toji was leaning back in his chair, legs spread wide, dress shirt unbuttoned at the collar, revealing the hard planes of his chest and the edge of old scars. His tie was loose, sleeves rolled up over thick forearms. He looked like a predator pretending to be civilized.
“Professor Fushiguro, I wanted to discuss my grade on the last assignment. I—”
“Close the door.”
You did. The click sounded too loud.
He didn’t invite you to sit. Instead he stared at you with those sharp eyes, jaw tight. “You really don’t get it, do you, princess?”
Your heart hammered as your face did a thing like ‘huh! What did he called me.’
“Get what, sir?”
Toji stood up slowly, all six-foot-something of solid muscle towering over you. He circled his desk like a shark, stopping right in front of you. Close enough that you could smell his cologne mixed with something darker you weren’t able to name.
“You walk in here every day looking like a fucking wet dream. Tight little sweaters, those skirts that ride up when you sit, legs crossed like you’re begging someone to spread them. Perfect grades everywhere else. Teacher’s pet everywhere but my class.” His voice dropped lower.
“You think I don’t see how you look at me? Like you want me to bend you over my desk and ruin that good-girl act.”
Your face burned. You hadn’t—well, maybe you had stared a little too long sometimes those biceps looked too good to be true. He was terrifyingly hot in that dangerous way.
“I—I don’t—”
“Bullshit.” His big hand shot out, grabbing your chin roughly, forcing your head up. His thumb pressed against your lower lip. “I’ve been hard as a fucking rock every lecture watching you squirm under my stare. You’re distracting me. So I’ve been making your life hell to keep you at arm’s length. But I’m done pretending.”
Before you could respond, his mouth crashed down on yours. It wasn’t gentle. Toji kissed like he fought brutal, demanding, all teeth and tongue. He tasted like black coffee and sin. His other hand gripped your waist, yanking you flush against him so you could feel the thick, heavy bulge straining against his slacks.
You whimpered into his mouth. He groaned, low and filthy. “That’s it. Make that pretty noise again.”
He shoved you back against the desk, papers scattering. In one motion he lifted you onto it, stepping between your thighs and hiking your skirt up to your hips. His palm slid up your inner thigh, rough and calloused, until his fingers pressed against the soaked fabric of your panties.
“Already dripping for your professor? Nasty little slut.” He chuckled darkly, shoving your panties aside and dragging two thick fingers through your folds. “This tight cunt’s been aching for me to wreck it, hasn’t it?”
You moaned, hips bucking. He pushed both fingers inside you without warning, curling them deep and pumping hard. The wet, obscene squelching sound filled the office. Toji watched your face with a smug, predatory grin, scissoring his fingers while his thumb rubbed brutal circles on your swollen clit.
“Look at you. Perfect student falling apart on my hand. Bet you touch yourself thinking about this, don’t you? Fantasizing about your mean old professor stuffing you full.”
“F-Fuck—Professor—”
“Call me Toji when I’m knuckle-deep in your pussy,” he growled, adding a third finger and stretching you mercilessly. You cried out, gripping his shoulders. He was relentless, finger-fucking you until your thighs shook and you came hard, gushing around his digits with a broken sob.
He didn’t give you time to recover. Toji yanked his belt open, shoving his slacks and boxers down. His cock sprang free. Thick, veiny, and intimidatingly long, the head already leaking. He stroked himself once, smearing precum.
“On your knees. Now.”
You slid off the desk on shaky legs and dropped. He fisted your hair, not gentle, and slapped his heavy cock against your cheek.
“Open that smart mouth.”
You obeyed. He thrust in deep, hitting the back of your throat immediately. “Fuuuck, that’s good. Take it all, baby. Choke on professor’s fat dick.”
Tears pricked your eyes as he fucked your face, hips snapping forward with zero mercy. Saliva dripped down your chin. He groaned every time you gagged, praising you in that rough voice… “Good girl. Such a nasty throat for me. Knew you’d look perfect with my cock down it.”
He pulled out suddenly, strings of spit connecting your lips to his glistening shaft. Toji hauled you up, spun you around, and bent you over the desk. Your cheek pressed against scattered papers as he kicked your legs wider.
He rubbed the fat head of his cock along your soaked slit, teasing your clit before pushing in—slow at first, letting you feel every thick inch splitting you open.
“Shit— so fucking tight. Gripping me like a vice.” He bottomed out with a grunt, balls deep, your walls fluttering around the intrusion.
His massive bicep suddenly hooked around your neck from behind, yanking your upper body up and back against his solid chest. His thick arm crushed your face into the crook of his elbow, squishing your cheeks together painfully while his forearm pressed firmly against your throat. The pressure was immediate and overwhelming—your face trapped, cheeks mashed, lips parted in a forced pout as he choked you with raw muscle. You could barely breathe, just desperate little gasps, your vision blurring at the edges.
Then he started moving. Hard. Deep. Animalistic thrusts that made the desk creak. His hips slapped against your ass, the sound wet and filthy. One hand gripped your hip hard enough to bruise; the other reached around to rub your clit.
“No more bullshit grades. You’ll get an A every time you come in here and let me fuck you stupid.”
You were moaning loudly, uncontrollably, pushing back to meet every brutal thrust. He leaned over you, biting your shoulder through your shirt as he pounded you.
“Gonna fill this cunt up. Breed you right on my desk like the little whore you are for me.”
The angle hit that perfect spot over and over. You came again, screaming his name, pussy spasming around his cock. Toji snarled, slamming in deep and staying there as he unloaded—hot, thick ropes of cum flooding you, so much it leaked out around his shaft.
He stayed buried inside you for a long moment, catching his breath, then pulled out slowly. You felt his cum drip down your thighs.
Toji smirked, tucking himself away and pulling your skirt back down like nothing happened.
“Fix your lipstick before you leave. And next time you turn in an assignment…” He leaned in, voice low and dark against your ear. “Wear something easier to rip off. Class dismissed, princess.”
You stumbled out of his office on trembling legs, his cum still leaking out of you, already wondering when you could piss him off again.
