"Good evening, Professor."

Sputtering, he set the glass down sharply and whirled towards his bed. There, under the comforter with her glossy head full of curls splayed out over a pillow, lay Hermione smiling sweetly at him.

Stalking over to the bed, he roared, "Get out of my bed this instant!"

Grabbing the corner of the comforter, he yanked it back and froze, feeling his mouth drop open. With the exception of the carefully applied eye makeup, Hermione lay naked as the day she was born.

Battling instant lust and anger, Severus grabbed the top sheet and threw it back over Hermione. Raising his eyes to the ceiling, he spoke in a low, pained voice. "Up. Out. Now!"

Sitting up slowly, with her eyes on his upturned face, she put her legs over the edge of the bed and stood, letting the sheet fall from her. She let her eyes rove over his body and felt her mouth watering at the sight of his broad shoulders and narrow waist. My goodness, what he's been hiding beneath that robe! Walking up to press boldly against him, she pulled his head down to force his gaze on her.

"Still immune to my charms?" she asked huskily.

Gritting his teeth, he shut his eyes, and growled, "I'm giving you one last warning. Get dressed and leave!"

Melting her body into his, she clearly felt his response against her belly and her heart rate doubled. Reaching up to plant a soft kiss on his jaw line, she purred into his ear, "Or you'll do what? Spank me?"

Lowering his head, he gazed down at her nakedness with a dark intensity, eventually raising his eyes to hers. The long silence very nearly unnerved her. Taking slow, measured steps forward, he backed her into the wall, resting one hand on each side of her head. With a voice of rough silk, he rasped "You have no idea what you're playing with."

Swallowing hard, Hermione felt her knees weaken. Reaching her hands around his back, she reached up and drew her nails down his back, feeling his shivering response. "Maybe you can teach me," she said in a shaky voice.

It was the tremor that caused him to snap. Swiftly grabbing her arms, he raised them above her head, clasping her slender wrists in one large hand. Pressing the lower half of his body sharply against hers, he roughly ran his hand over the smooth contours of her hip, waist and full breast, keeping his intense gaze locked on her face. Thumbing her nipple, he took advantage of her indrawn breath by tilting his head to thrust his tongue into her mouth, closing his mouth hotly over her own. Feeling her muscles turn liquid, Hermione stepped on tiptoe to press back against him. Being held naked in the arms of a fully dressed man added a sharp edge to the already erotic.

At the sound of her low moan, Snape jerked back, and breathing heavily, backed away from her with dark, furious eyes. Running a shaky hand through his hair, he pivoted and stalked over to the fireplace, tossing down the rest of his drink in one shot. Feeling like a complete pervert, he uttered, "Forgive me. I forgot myself."

Stepping forward, Hermione started to protest. Halting her words with a raised hand, he spoke, "It won't happen again."

Frustrated by the turn of events - her body felt like one throbbing nerve - Hermione strode over to him and shoved her hands against his chest. "You want to bet?"

Catching her wrists once more, he snapped at her, "Until you're of legal age, you are a child. It would behoove you to act like one. I certainly plan on treating you like one."

"Meaning?" she growled.

"Meaning … the next time you attempt to throw yourself at me, you'll find yourself over my knee so fast your head will spin. And this time, I won't be gentle."

Crying out in frustrated rage, she raised a foot and brought her heel down on his instep, pulling her wrists at the same time. Grunting in shocked pain, he held onto her wrists in a deathlike grip, amazed at her temerity.

Limping and dragging her towards the bed, he ground out between clenched teeth, "Fine! Have it your way."

Sitting on the corner of the bed, he tossed her squirming and kicking, over his lap. Pressing one hand firmly on the small of her back, and shifting his thigh to place her in the best position for attack, he raised his hand and brought it back down on her naked buttocks in a tremendous smack, perversely pleased at her cry of outrage. Putting more strength into each swat than he had on the previous occasion, he spanked her fast and furiously, tunneling his sexual frustration into each powerful swat. He stopped only when he became aware of her helpless sobbing, noting the extreme redness of her abused backside.

Lifting her to curl up crying on the bed, he strode over to grab his robe where it lay, and draped it over her naked form. Wrapping her in its folds, he picked her up in his arms, awkwardly tossed powder into the fireplace with a short command, and stepped inside with his burden.

Exiting the fireplace in Hermione's room, he placed her in her own bed, covering her before spinning to make his exit. With her quiet sobs echoing in his ear, he returned to his room, and cursing foully, walked over to punch his fist into his chest of drawers, knocking the contents along the top onto the ground.

He needed advise. He needed to speak to Dumbledore.
