Velvet and Claws

Professor Snape was sleeping peacefully within the darkness and silence of the dungeons, blissfully unaware of the intruder within his rooms. Nearly silent, the intruder pushed aside the dark velvet curtains guarding his bed. With a practiced spring, she landed beside him, stalking up his chest to lick his impressive nose. When this had no effect, she took out a single claw, running it from his ear down to his exposed collarbone. This had the effect she sought. Severus Snape's eyes slowly opened, narrowing at the intrusion.
“Hello, Pussy,” he purred at her. Behind his velvet tones lay both menace and promise. He knew what this intrusion could only mean. He knew he was like catnip to her. The impatient and hot tempered witch chose that moment to return to her human form, the change tearing the breath from him as her body pressed suddenly into his. “Severus,” she purred at him in return, noting just how happy he was to see her.
Reaching up, he pulled the pins from her tightly bound hair, allowing it to cascade down her shoulders and softening her schoolmarm appearance. She chuckled, her voice warm and throaty with her Scottish accent, and leaned in for a deep, demanding kiss. It was all the convincing he needed. He held her lips firmly to his, hands slowly running through her hair, down her neck, over her shoulders. She began peeling the bedclothes away from his lean but masculine form, fascinated as always with the scars he still bore, despite magic's healing capabilities. She ran her fingers over them, ending with the dark mark he bore on his left forearm. The pull of the darkness within him was not something she could easily shrug off. Nor admit to.
Noting her preoccupation, he picked her up, hoisted her over him and landed neatly above her,reversing their last position. His dark curtain of hair fell over one eye, a wicked expression on his face. This was not enough warning for the Gryffindor who suddenly found her legs above her head, resting neatly upon his shoulders as he went straight for the first course. Delighted to find her knicker-less, he still could not help but comment on the tastelessness of her tartan garter belt. He wondereded aloud if she would attempt to change the school uniforms to tartan, given the headmistressship. “This from the man who is terrified of color,” she responded tartly, pulling him closer with her legs, still wrapped 'round his neck.
Always a subtle man, he had no trouble understanding her Gryffindor hint. He licked her delicately, teasing her folds and nosing her clit. Delving deeper, he was rewarded with a throaty moan. He could feel her gripping him closer, clenching around his intrusion. Encouraged, he generously inserted one of his long, shapely digits deeply within her, stroking her smooth, damp tunnel. Severus knew how to make a kitten purr.
However, his concentration was broken when he felt her fingers softly cup his balls on the way to his erect and throbbing manhood. She softly kneaded his flesh, sighing as she felt him grow within her grasp. As she stroked him he grew damp, her hand sliding over the silky skin. Reaching for her own moisture, McGonagall augmented the wetness glistening along the length of his hefty rod.
“Ah dinna think ah kin wait inna lönger.” McGonagall purred. She twisted within his grasp, becoming a cat once more, then swiftly reforming into a very lusty Scotswoman. She mounted him, teasing his impressive erection for a few moments before her impatience got the better of her. Snape pressed upward, forcefully inserting himself into her channel. She groaned and bucked, pulling him forward for a forceful kiss as she ground her hips against his. Sensation rendered them both inarticulate. All arguments and rivalries were lost to the pleasure they gave one another. Hot, desperate, wet, hard. The two of them were lost within the storm, emerging from its center only after it was spent.
Panting, they broke apart, only to settle themselves comfortably. No one would notice the cat with the spectacle markings around her eyes leaving the dungeons in the first light of morning. No one ever had.
