A bisexual trainer introduces her submissive partner to the world of pegging, humiliating him by forcing him to lick and suck her strapon before fucking his ass with it. The bi-sexual power dynamic intensifies as she commands him to pleasure her with his mouth and hands while she teases his prostate with the strapon. They switch roles, the submissive now dominating his trainer, strapon-fucking her and bringing them both to an intense, bisexual climax.
