This is the first in a series of oneshot gifts for my good friend Herves Vuin. This is in misc crossovers because the next one will have characters from different genres in it, not just Harry Potter. Also, I don't own Snape. I just wish I did.

Get well soon, dear!

Yawning, Mary took the package from the delivery person, opening the box curiously once she got inside. It was a book, with a green leather cover, very tattered and worn. A letter fluttered out and to the ground, making her set the book on the table as she bent to pick it up. She turned the parchment in her hand as she sat down on the couch, reading it silently.

Only read this when you are alone, and are not to be disturbed.
It will bring a dream to life for you. Look for more volumes in
the future. It would be wise to tell no one of this.

It was unsigned, and Mary didn't recognize the handwriting. With a shrug, she stood and moved to her bedroom, settling down with the book. As she opened it, a wind swept through the room, ruffling her hair and sending the pages of the tome flipping wildly. Mary closed her eyes, shrieking a little as the wind continued.

When it finally died down, she opened her eyes, gasping as she looked around; she was no longer in her room, but in a dimly lit class room, with cauldrons set around the work stations. At the front of the room, she could see a tall figure dressed in black, with dark hair hanging down to his shoulders. Mary stepped closer, biting her bottom lip as she walked, stopping dead when the figure turned around. She immediately recognized the pale face and dark eyes, the high buttoned collar with the dark cloak; Severus Snape.

"This is impossible.... You aren't supposed to be real!" she gasped, walking closer again. He smirked, flicking his hair from his eyes as he strode toward her.

"This book brings a dream to life, as you should have read in the note that came with it," he said softly, wrapping his cloak around himself, staring down at her. "The setting and your companion are described, but what happens is up to you."

"But how-" she began, cut off by Snape's raised hand. She watched in shock as his hand moved to brush over her cheek, curling gently into her light brown hair, dark eyes meeting her aquamarine ones.

"Do you always question everything? This is your fantasy... I wouldn't squander it on curiosity." He bent to her level, his lips brushing hers for a moment before crashing down on them. Mary moaned softly into the kiss, arms moving around his neck as his slid around her waist and tugged her closer. He broke the kiss as he backed her into his desk, setting her back on it as his hands traveled over her thighs slowly, his eyes never leaving hers. "You bewitch me, my dear... I hardly can keep my hands from you, and I have no desire to try..."

Mary gasped as he bent in, biting her neck somewhat roughly, his tongue laving where his teeth marked her. The gasp turned into a moan as she felt his hand moving up her thigh to probe under her skirt. He slowly massaged her sex through her underwear, pushing them aside to rub her properly. Her breath hitched as he removed his hand, sliding it up to hook in the waistband of the panties, dragging them down over her legs. She leaned back, bracing herself against the desk, watching as he bent to unbutton her blouse, kissing each inch of revealed skin.

"My turn," she whispered, sitting up and sliding her hands over his chest. She began working at the tiny buttons, shuddering as he stroked his fingertips over the sensitive skin of her stomach. Even before she finished with the black shirt, she saw she would have to unbutton the white one underneath; she was far too impatient for that; she simply ripped open the shirts in one go, leaning in to kiss the smooth, alabaster skin revealed to her. He growled softly, lifting her hips as he slid down her skirt, tossing it away with the rest of her clothes. Lastly, he unhooked her bra, pulling it down over her arms, then pushed her back down onto the desk, his lips closing over one dusky peak.

Her hands tangled in his hair, holding him to her as his other hand massaged her breast. His head raised as he moved to stand between her legs, pushing down his pants. "So beautiful... Mary..." he whispered, sliding in gently. She groaned as he filled her so completely, she thought she would burst. Then, he began to move. Her back arched, knees wrapping around his waist to hold him to her as he thrust within her, slow and deep. Severus' dark eyes looked into her blue-green ones, one of his hands caressing her cheek gently. She gasped as she heard him growl low in his throat and begin to thrust harder into her, the gasp turning into a moan, the moan turning to a cry. She clung to him tighter, his teeth at her neck driving her pleasure even higher.

"Severus... I..." She was cut off by her own pleasure, her body trembling in Snape's arms before she broke around him, her cries turning into screams as he continued to push his long, hard length into her. She gasped as he groaned and shuddered, thrusting into her one last time and flooding her with his heat. She fell back panting, moaning as he pulled out of her. Her head raised in alarm as she felt him kneel between her legs, kissing over her thighs. "Oh my God...." she moaned, arching as she felt his tongue tracing over the petals of her sex, only to plunge inside her a moment later. She whimpered softly as he moved to trace over her bud, slipping two fingers within her.

His dark eyes looked up at her, his intense gaze boring through her as his skillful touch and tongue stroked her ever on. Mary's body tightened as he flicked his tongue rapidly, arching and bucking against him as the waves of pleasure crashed over her again. She fell back, panting as he moved back up over the desk, placing one hand on either side of her head. He bent to kiss her forehead as the room swirled, taking him with it.

Mary gasped and sat up on her bed, panting softly. She looked down at the book, still open next to her. On the page was a sketch of Severus Snape in his potions classroom, just as she'd seen him when she'd first entered the fantasy. She closed the book, putting it beside her bed and walked out with a smile on her face.
