A/N: Sorry to keep you guys waiting. For two days. Hope it wasn't that bad. Thanks for reviewing, if you hadn't, I wouldn't have written these chapters. ;-) Enjoy. Snape is one dirty professor, non?

He squeezed them lightly, his thumb flicking over her nipple as it hardened. Then he moved his mouth to her breast, and with his teeth grazing over the top, pulled down her bra with his teeth. She shuddered.

"Gods, you're sexy, Professor," Hermione whispered.

Snape paused and looked up at her, her mouth slack with pleasure. "I'm just warming up," he purred. He took her breast into his mouth, lightly sucking and nibbling with his teeth, as Hermione grew more and more aroused. Her hands moved up and down his back as he moved to her other breast. Hermione started shuddering, and Snape took advantage of this moment to sweep his experienced fingers, delicate yet determined, down to her heated core, and he flicked at her clit with her breast still in his mouth.

"When you come, I want you to scream my name," he hissed, taking a breath. "You wanton little..."

But Hermione had kissed the words right out of his mouth. The Potions Master welcomed the kiss, and explored her mouth gently, insistently, taking time to savor the sweet taste and all the fiery passion. Hermione had never been kissed like this before, and her whole body was alight with the sensation. She tingled all over, not just from his kiss, but from his ministrations below. She couldn't keep still and wiggled, trying to get away from his fingers but also trying to mash them against her harder.

Hermione buckled again and then came, so completely at his mercy. "Oh, Severus," she panted, the orgasm wracking her body with pleasure as the sensation slid to her toes and back again in waves.

Without giving her the time to recover, Snape placed his hot, hard organ at her entrance, almost devouring Hermione with his gaze. She stared at his torso, littered with scars, and was so hungry for it she almost pulled him into her. She wrapped her legs around his torso, but he resisted.

"When I'm ready, I'll let you know," The Potions Master said cruelly, and then, with a brutal stroke, he rammed into the hot witch. Her tight sleeve was welcoming to him as he slide in and out of her heat, pounding her until her eyes rolled up in her head. It was warm and it shuddered around his cock, squeezing delightfully. The perfect amount of pleasure.

"You are exquisite," Snape hissed at her. Hermione couldn't answer. All words had been lost as the Professor pummeled her into an even higher state of arousal. Every stroke, every hot dirty word he whispered into her ear, made her yearn for him even as he was driving her against the desk. "Shit," she murmured. His cock stroked against her clit and she came again. Severus resisted the urge and rode her out.

"I treasure this moment," he whispered, "rendering the little know it all speechless. Turns out all you needed was a good dose of this hot, hard, cock." Hermione couldn't help it, she came again and her walls clamped tight against Severus. He almost lost it, but drove her one more time, brutally, to the edge of consciousness, her body a delicious check on him. He came, filling her body with it, and pulled out with a satisfying sound. He groaned and put his head down next to her, his body still between her legs. He fondled her breast again and she smiled as he moved his head there and bit it slightly. She had one last orgasm, riding out the final waves, and sighed.

"Fuck," she whispered. "I have never been... gods. You're amazing, Severus."

"You don't have to tell me twice," he smirked, wickedly. "This is only the beginning."

That night, Hermione arrived back in the common room, sweaty but looking very satisfied.

"What are you smirking about?" Ron gaped at her. "Weren't you just in the dungeons?"

"No, Sev- I mean, Snape let me out earlier, I decided to have a walk around the Quidditch field."

"Oh really? You didn't want to head to the library for some mental exercise?"

"Stop giving her such a hard time," Harry chastised Ron. Harry looked at Hermione. "He's still upset because you didn't listen to him complain about Lavender today. Boy, you really missed out." Ron roughly elbowed Harry in the ribs, and Harry, despite himself, laughed.

Hermione smiled gently at her friends, all the while secretly remembering Snape, only an hour before, taking her brutally, mercilessly, against the desk. She almost came again just thinking about it.

"I have to go upstairs, I'm worn out," Hermione said to the boys, and walked up the stairs. She couldn't sleep, though, as visions of Severus continued to flit through her brain. Every hot, dirty word had burrowed itself into her mind, and her brain had decided to be on "repeat" all night.
