A/N: First time writing a lemon story. I've always been intrigued by the idea of Hermione and Snape together. This will also have some scenes with other characters in future chapters. Until then, I hope you all enjoy the lemony goodness. All feedback is greatly appreciated!

Chapter One
Giving into Desire

Hermione slammed the door behind her, the sound echoing in the nearly empty hallway.

"This is ridiculous," she snapped, tossing her bag onto the chair across from his desk. "I deserve at least an E (Exceeds Expectations) on that paper."

Snape didn't even look up from the stack of essays he was grading. "Your essay was poorly written, considering your reputation, Miss Granger. Everything about it seemed to lack any effort. An A (acceptable) was generous." His voice was low, controlled—completely unfazed by her outburst.

Her hands curled into fists. "You're being unfair. You've been on my case all year."

He finally lifted his gaze, and the moment their eyes met, something crackled between them—sharp, electric, undeniable.

He exhaled, setting his quill down with deliberate slowness. "If you think I'm treating you unfairly, Miss Granger, then prove me wrong."

She didn't back down. Instead, she stepped closer, pressing her palms against the desk. "Maybe if you weren't so determined to find flaws in everything I do, you'd admit that I'm one of your best students."

A muscle ticked in his jaw. His patience was wearing thin. But she was right, she was the brightest in her class. Her wit matched that of Lily Potter. And her attitude reminded him of her very much. He noticed her from the moment she stepped into his classroom. But she was far too young. Over the years, she had her body began to develop maturely. It pained him so much that he started to despise her.

"That confidence of yours is impressive," he murmured, leaning back in his chair. "But confidence isn't the same as competence."

Her breath hitched. He was infuriating. He was also dangerously attractive—his sleeves rolled up, the top button of his shirt undone. She hated that she noticed. She hated him even more when his eyes had dropped to her lips for the briefest second. Ever since her first potions class, she had found herself attracted to him. But with her friends, she couldn't say anything. Over the years, her yearning increased, and she found herself having fantasies about him. Slightly turned on every time he looked at her. What's worse was that last year, while they were in Grimmauld Place with the order, she found herself looking at him more desperately.

The air between them shifted, heavy with something unspoken.

She should walk away, but something inside her burned.

Instead, she pushed him. "You love this, don't you? Holding all the power. Watching me squirm."

His expression darkened. He stood, the space between them shrinking in an instant. He wasn't going to let her intimidate him, even though all he wanted was to take control of her body.

"Is that what you think?" His voice was dangerously quiet now.

She swallowed hard as she stood her ground. "I think you like getting under my skin."

His fingers brushed her wrist, just barely, but it was enough to make her shiver. "And what if I do?"

She knew this was wrong. But when his lips hovered inches from hers, daring her to pull away, she didn't.

Instead, she tilted her chin up, breathless, and whispered, "Then stop pretending."

The last shred of restraint snapped. Snape lost all his control and let his lust take over.

His mouth crashed against hers, fierce and unrelenting, as his hands gripped her waist, pulling her flush against him. She gasped into the kiss, her fingers tangling in his hair, giving back just as much as he demanded.

This wasn't a mistake.

It was inevitable.

Snape broke off the kiss as they both gasped for air. She should leave, he thought. It was too risky, having an affair with a student. He could get in serious trouble. Hermione thought the same thing, but her arousal took hold of all her senses. She sat on the edge of his desk, her skirt bunched high on her thighs, staring up at him with a challenge in her eyes.

"Tell me to leave," she murmured.

Snape's jaw was clenched so tight she thought he might break. His fists curled at his sides like he was physically restraining himself.

"You don't know what you're asking for," he said, voice low, dark.

She leaned closer, lips barely brushing his ear. "Yes, I do."

Something snapped when he felt her hot breath against his skin. She was so close to him, he could taste her perfume. A growl rumbled in his chest as his mouth crashed against hers, hands gripping her waist, pulling her flush against him. She moaned into the kiss, tangling her fingers in his hair, gasping as his hands roamed lower, squeezing, claiming.

Then, suddenly, he was lifting her—her legs wrapped around his waist as he set her on the desk, scattering papers to the floor. His lips trailed down her jaw, her throat, her collarbone.

"You drive me insane," he muttered, his fingers already working the buttons of her blouse.

She shivered as the fabric fell away, leaving her in just a black lace bra. His breath hitched. "Merlin."

His hands slid up her stomach, teasing over the curve of her breasts before he pulled the straps down her shoulders. Then, with one flick of his fingers, he unclasped her bra, revealing her taut nipples. She gasped as the cool air kissed her bare skin, but then his mouth was on her, hot and wet, his tongue flicking over her nipple before sucking it between his lips. He swirled his tongue as his other hand massaged her other breast. She could feel herself getting wetter with all the pleasure she felt.

"Ahhhh," A broken moan escaped her throat as she arched into him.

"Please..." she whimpered.

His hands slid lower, unzipping her skirt and peeling it off completely. A sharp inhale left him as he took in the sight of her—spread out on his desk, wearing nothing but lace panties that were already damp from his touch.

"Fuck—" he groaned, palming himself. His member already rock hard from just the sight of her.

She bit her lip, eyes locked on the hard length straining against his pants. "Take them off."

His gaze darkened.

Slowly, deliberately, he unbuckled his belt, the leather sliding free with a whisper of sound. Then the zipper. Then his pants hit the floor, leaving him in just his briefs—thick, hard, the outline of him making her thighs clench.

She reached for him, but he grabbed her wrists, pinning them above her head.

"Not yet," he rasped. "I want to take my time with you."

Her breath caught. "Severus—"

But then his fingers hooked into the waistband of her panties and dragged them down her legs, leaving her completely bare beneath him.

He stared, heat flaring in his eyes."So fucking perfect."

She barely had a second to breathe before he was on his knees, spreading her thighs and running his tongue over her slick folds.

"Oh my—" Her head fell back, a desperate moan ripping from her throat.

He licked, sucked, teased, his tongue swirling around her clit before dipping lower. She was already trembling, her body wound tight, pleasure building too fast.

"Severus, I—"

He gripped her hips, holding her down as he devoured her. "Cum for me."

And she did—her back arching off the desk, her legs trembling as she shattered beneath his mouth.

He didn't stop. Not until she was whimpering, her body too sensitive to take any more. Then he stood, yanked down his briefs, and positioned himself between her legs. Her eyes dropped to his cock—thick, hard, the tip already smirked, stroking himself as he watched her squirm. "You ready for me?"

She nodded, breathless. "Please."

With one slow, torturous thrust, he pushed inside her, stretching her inch by inch until he was buried to the hilt. She gasped, nails digging into his shoulders. "Fuck—"

Snape groaned, his head falling forward. "Uhhh. So fucking tight," he muttered, pressing a kiss to her throat. "So perfect."

Then he pulled back and slammed into her moaned louder, hands gripping his back, hips meeting his thrusts as he fucked her hard and pace was brutal, relentless. The desk creaked beneath them. Papers scattered to the floor. She clung to him, moaning his name like a prayer.

"Say it again," he demanded, voice rough.

"Severus!"

He groaned, gripping her thigh and pulling her leg higher, hitting even cried out, body tightening around him, pleasure winding sharp and hot in her core. "I'm gonna—"

"Cum for me," he growled.

And then she was gone—blinding pleasure crashing through her as she came hard, her walls pulsing around him. A deep, shuddering moan tore from his lips as he followed, his body tensing before spilling inside her, his breath ragged as he collapsed against her. For a long moment, neither of them moved.

Then, slowly, he lifted his head, brushing a kiss against her swollen lips.

"That was…" he started, but words failed him.

She let out a breathless laugh. "Yeah. It was."

Reality started creeping in—the weight of what they'd just done.

The air between them was thick with heat, the scent of sweat and sex lingering as they caught their breath. Snape was still inside her, his weight pressing her into the desk, his forehead resting against hers.

He should stop.

They both should.

But when she shifted beneath him, squeezing around his still-hard cock, a sharp groan ripped from his throat. His hands gripped her hips like a warning. "You're playing a dangerous game, Miss Granger."

She smirked, breathless. "Maybe I like danger."

His restraint a word, he flipped her onto her stomach, her bare skin flush against the cool wood. She gasped, barely able to process the shift before he grabbed her by the hips, dragging her back onto his cock in one ruthless thrust.

A sharp, broken moan escaped her lips.

"Fuck—"

"Too much?" he rasped, voice thick with lust, but he didn't stop.

She whimpered, pushing back against him, desperate for more. "No—don't stop."

He groaned, his grip tightening. He pulled almost completely out before slamming back in, the force of it making her cry out. His pace was rough, brutal—no more hesitation, no more restraint. Just raw, desperate need.

The desk creaked beneath them, the sound of skin slapping against skin filling the office along with her moans, his groans, the sheer filth of clawed at the desk, her body on fire. "Severus oh, fuck—"

His hand slid up her spine, pressing her down, trapping her beneath him as he fucked her harder, deeper.

"You feel that?" he growled, his breath hot against her ear. "You're dripping down my cock."

She moaned helplessly, her thighs trembling as pleasure coiled sharp and tight in her core. His fingers tangled in her hair, yanking her head back just enough to make her gasp. "You love this, don't you?"

"Yes—Merlin, yes."

His free hand slipped between her legs, his thumb pressing against her whole body jerked, her moans turning into desperate, high-pitched cries.

"Cum for me," he ordered, voice rough and commanding.

She shattered. A strangled moan tore from her throat as her orgasm ripped through her, her body tightening around him in waves.

"Fuck—" Snape groaned, slamming into her one last time before he followed, his grip bruising as he spilled inside her, his body shaking from the force of it.

For a long moment, neither of them moved.

Then he collapsed onto her, both of them spent, breathing heavy, skin slick with sweat.

She let out a breathless laugh, still trembling. "I— I can't feel my legs."

He chuckled, pressing a lazy kiss to the back of her neck. "Good."

Silence settled between them, thick and should have sunk in by now.

The consequences. The lines they'd crossed.

But as he pulled her against him, his hands roaming her body like he still wasn't done, she knew one thing.

This was far from over.
