When Lavender spread her legs like that for him, his eyes rolled up in to his head and his breath came out in a rasp. "Oh dear gods, further," he instructed, placing his hands on the inside of her thighs and stretching her more. She was so wet she glistened in the moonlight and her moved down the bed, achingly out of her grasp. Cormac dipped his head and licked up her inner thigh quickly, taking a quick taste of her next. He positively throbbed at her reaction before pushing his tongue flat against her sex and sliding his body down the bed to lie between her legs and continue teasing her with his tongue. Before long he could feel her tightening but he didn't want her coming just yet so he stopped, crawling up her body while licking his lips of the taste of her and then kissing her, hard.
While they kissed, he used his knees to spread her legs once more and then thrust into her, putting all of his body weight and momentum into the movement, keeping his word about fucking her straight into the bed and beyond.
