Chapter Text
Y/n fidgeted with the hem of her skirt as she stood outside Severus Snape’s office, the heavy oak door looming before her like a barrier between her and the rest of the world. She had messed up her potion again—this time, the cauldron had exploded in a puff of purple smoke, coating the ceiling and half the classroom. She swallowed hard, her stomach twisting with nerves. Detention with *him* was always worse than a week of detentions combined.
She knocked once, her knuckles trembling.
"Enter," came his dry, commanding voice from within. The door swung open under her touch, revealing the dimly lit office, the scent of old parchment and something musky—his cologne, maybe—filling the air
The flickering torchlight in Severus Snape's office cast long, ominous shadows across the stone walls, the air thick with the musty scent of old potions and damp earth.
Y/n stood just inside the heavy oak door, her heart pounding like a trapped bird in her chest, the hem of her school skirt brushing against her knees. At this point, she was no stranger to this room; detention had become a familiar ritual, her defiant streak clashing with the rules of Hogwarts in ways that always landed her here. But tonight felt different—the way Snape's dark eyes bored into her from behind his desk, his thin lips curled into a sneer, sent a shiver down her spine that wasn't entirely from fear. She shifted on her feet, her cheeks flushing as she met his gaze, her shyness warring with the spark of rebellion that had gotten her into trouble again.
Severus sat behind his desk, his dark eyes lifting to meet hers with that infuriating, knowing smirk. "Ah, Miss Y/n. Right on time." His gaze raked over her, slow and deliberate. "Come in. Close the door."
She obeyed, her pulse hammering in her throat as she stepped forward. The floorboards creaked under her feet, the silence between them thick with unspoken tension.
Snape leaned back in his chair, fingers steepled under his chin. "You know why you’re here."
Y/n bit her lip, her cheeks burning. "Yes, sir."
"Another detention, Miss Y/n," Snape drawled, his voice a low, malicious purr that echoed in the confined space. He rose from his chair, his black robes swishing like a predator's cloak, and circled around the desk toward her. At thirty-six, he exuded an authoritative presence that made the room feel smaller, his sharp features and hooked nose giving him a hawk-like intensity. "Your insolence knows no bounds. Perhaps it's time for a lesson that will finally make you compliant."
Y/n's breath hitched as he loomed over her, his tall frame blocking the light, and she opened her mouth to protest, but the words died on her tongue when he grabbed her wrist. "Bend over the desk," he commanded, his tone brooking no argument, though a cruel glint in his eyes suggested he relished any she might offer.
She hesitated, her shy nature clashing with the defiance bubbling inside her, but the firmness of his grip left little choice. "But Professor, that's not fair—I didn't mean to—" Y/n stammered, her voice a mix of complaint and reluctant submission as she leaned forward over the cold wooden surface, her palms pressing into the scarred desk.
Snape wasted no time, his long fingers hiking up her skirt to expose her white cotton panties, the fabric clinging to the curves of her ass. With a swift, authoritative pull, he yanked them down to her thighs, the cool air hitting her bare skin and making her pussy lips twitch with unwelcome exposure.
She gasped, mortified. "Sir—!" She squirmed, her face burning with humiliation, but his hand on her lower back held her in place. "Quiet, you insolent girl," he snarled, his voice laced with snark. "This is what happens to naughty students who think they can defy me."
There was a moment of pause. The first smack landed with a sharp crack, his palm connecting solidly with her right ass cheek, the impact sending a jolt of stinging pain through her flesh.
Y/n gasped, her body jerking forward, the sensation radiating outward like fire, her skin blooming red under his touch. He didn't pause, delivering another blow to the left cheek, harder this time, the sound echoing off the walls like a whip. Her ass jiggled with each strike, the soft flesh reddening and swelling, and she bit her lip to stifle a whine, her pussy growing slick against her will from the mix of pain and something deeper, more primal.
Snape's breathing grew heavier, his cock stirring in his trousers as he watched her reactions, his hand rubbing roughly over the heated skin before the next slap. "Take it, you little brat," he growled, his voice thick with malicious pleasure, "feel every bit of this punishment."
As the spanking continued, Y/n's complaints turned to muffled whimpers, her initial defiance melting into reluctant compliance with each punishing strike. Her ass was on fire now, the cheeks throbbing and sensitive, and she could feel the wetness between her legs seeping onto her thighs, a betrayal of her body's response.
Snape paused for a moment, his fingers tracing the welts he'd left, dipping lower to brush against her pussy lips, already swollen and slick. "Look at you, getting wet from this," he sneered, his tone dripping with contempt and arousal. "You're more of a slut than I thought."
Without warning, he roughly took both of her hand and tied them behind her back and spread her legs wider, then his hand came down directly on her cunt, the slap against her sensitive folds making her cry out. The pain was sharp, intense, her clit pulsing under the assault as he spanked her pussy repeatedly, the wet sounds of his hand meeting her soaked flesh filling the room.
By the time he stopped, Y/n was trembling, her hands tied behind her back with a length of cord he'd conjured, her body a mess of aching heat.
Snape's cock strained against his robes, and with a rough grunt, he freed it, the thick, veined shaft springing out, precum glistening at the tip. "Enough games," he muttered, positioning himself behind her, his hands gripping her hips as he thrust into her tight cunt in one brutal stroke. She screamed at the sudden fullness, her puffy and red pussy stretching around his dick, the pounding rhythm he set making her sore ass cheeks slap against his pelvis. "So fucking tight, you little whore," he groaned, his balls slapping against her with each thrust, "taking my cock like you were made for it."
Each thrust sent a jolt of pain and pleasure through her, her clit rubbing against the wood with every movement.
After a bit of pounding his grunts and moans started getting more frequent. His fingers found her naked clit, rubbing it roughly as he fucked her harder, her moans echoing in the room.
She sobbed, her body trembling as pleasure coiled tighter and tighter until she shattered around him, her cunt clenching as she came, and he followed, filling her with hot cum, his own release spilling inside of her.
"This is your punishment," he panted, pulling out slowly, watching his seed drip from her reddened pussy.
He tucked his cock inside of his robes again and untied her hands. Before she could process what had just happened, he helped her up, turning her to face him and settling her onto his lap. Her skirt was a lost cause, riding up to expose her bare, and exposed well-used pussy. Snape’s fingers traced idle patterns over her skin, his touch almost tender now. “There,” he murmured… "Was that so hard?”. Y/n shook her head, her cheeks still flushed, her body humming.
He cupped her face, his thumb brushing her bottom lip. "Good girl," he murmured, his voice thick with satisfaction. "Such a *good* girl."
His hand slid up to cup her breast under her blouse his thumb pinching her nipple and massaging her breast briefly.
She whimpered, her body still trembling from the aftershocks as he pulled her closer, his hands roaming her back, her thighs, squeezing her sore ass.
"You’ll be back for more," he murmured against her ear, his breath hot and possessive. "Won’t you?"
She nodded, unable to form words, her body still humming from his touch.
He smirked, pulling her skirt back down with a slow, deliberate tug. "Good. Because next time, I won’t be so gentle."
He crouched down, picking up her panties from the floor. "A reminder of who you belong to," he murmured, tucking them into his pocket. Then, with a smirk, he added, "And don’t think this means you’re forgiven. Next time, it’ll be worse."
Y/n could only whimper in response, her body still trembling from the force of her orgasm. She knew she should hate him. But as she pulled her skirt back down, her pussy still throbbing, she couldn’t deny she wanted more.
"Next time, Miss Y/n, *listen*" His voice was a dark promise. "Or I’ll make sure you regret it even more." Making her get up from his lap.
Y/n’s face burned as she straightened her skirt, her legs still weak from pleasure.
Snape watched her with cold amusement. "Dismissed."
And as she sat lies in her dorm bed, her pussy still throbbing, her ass still stinging, she couldn't help but wonder what other lessons Snape had in store for her.
