Sit on his face.

Now or never. you think to yourself, then mount the bed and put one leg over your husband, turning so that you're facing toward his feet. His body stiffens a little in surprise, but he doesn't say anything. You slowly start to lower yourself down on his face, feeling a little nervous and self-conscious. Then you feel his tongue on you. At first it's a tentative little touch, then he starts getting more aggressive, going deeper and harder like he's never done before. It's actually turning you on, which you didn't expect. You also see his cock quickly grow hard again, so apparently it's turning him on too.
