Facesitting on LetMeJizz
Control is the hook, one partner flattened on their back while she lowers her full weight down over their mouth. She grinds against a working tongue and dictates every bit of the rhythm from up top, leaving the person underneath to breathe whenever she allows it. Viewers come for that reversal, somebody smothered and serving while she takes her pleasure without asking.
