Whipping her ass

Berni was lying calmly on Snape\'s chest his breathing soothing her, his fingers running lazily through her soft hair. She kissed the base of his neck, his breathing increased. His fingers ran under her hair to the warm skin underneath, her mouth slowly teasing his skin all the way up to his jaw-line. She reached his ear and began nibbling at it, his ear was always a very sensitive area to him.
\"Are you in the mood tonight?\" she asked before continuing.
\"Once you start you know I can\'t resist you.\" he replied, his deep baritone suddenly husky.
He ran one finger down her warm skin, moving his other hand to the back of her head, he pulled her forwards so their mouths met their tongues twisting endlessly around each other, they broke his black eyes staring deep into her blue ones.

\"How would you like your sex tonight?\" he asked.
\"Slow but intense.\" they had been together long enough now to know what that meant. She slide her body down his muscular stomach and came across his quickly becoming erect cock, she looked back up his body and saw the trail of wetness she’d left over his beautiful body, his fingers had followed the trail and they were now being smoothered by his tongue as he took in the taste of her arousal.
He moaned his erection becoming complete, especially as she took the silky head into her hot mouth, slowly sucking and licking away his pre-cum. She pulled away, licking her lips. \"Mmm... something stirs in the woods.\" she whispered as she took his helmet into her mouth again.
\"Ohhhhhhhhhhhhh\" he moaned, his hands clasping around her head and his mouth gasping open in the pleasure of it all.

She pulled back tasting the nearness of his orgasm, his head was resting heavily on the pillow his eyes shut she had been right to stop at that moment his face was in that pleasure position it goes into just before an orgasm. (the calm before the storm!)
He opened his eyes, she was looking straight back at him, \"you\'re so good at that.\" his voice really showing his extreme arousal.
*Slight pause*
Before she suddenly thrust her hips forwards and his hardness slide into her, filling her to the brim, she rocked her hips slowly backwards and forwards. His hands running all over her body sliding over her silky skin.

She took it slow, letting him feel every stroke, every twitch of her muscles as she was beginning to reach for her goal. She was rising with him up to heaven, his eyes had closed again as she quickened the pace somewhat.
His normally regular and controlled breathing had gone out of the roof, his whole show, the sadisticness and the hardness, it just fell to pieces with her in his bed. But that didn\'t mean that he was going to give any gryffindor any lenience when it came to teaching mode.
He was so close, she was so close, their moaning if the door hadn\'t of been warded would surely have carried into the Slytherin common room nearby.

Then he released, his cock thrust completely inside her, his white hot semen driving her muscles into a complete frenzy. His groan of pleasure way out-striping her own, as her body collapsed onto him for the second time this evening.
