For a little while, she watched him, eyes half closed, not expecting much. But then he put his tongue like that and a gasp escaped her, a shiver racing up her spine. She was used to putting on a bit of a performance. She didn't know when she'd started doing it, but putting in the appropriate moans in the appropriate places seemed to encourage some of the men she fucked, so she gave the full porn-star experience. It didn't feel right to do that now though- as he got more into it, her thighs parted more and her hips rose to meet him, and she flopped back onto the sheets with her eyes closed, a real moan of appreciation coming out without her even trying.
