Pegging on LetMeJizz
Strap-on clips often pair two women, but the defining move here is a woman fucking a man with one. He takes it bent over or flat on his back while she works his ass, the role reversal carrying as much weight as the act itself. Reactions run from him stroking through it to full submission, but the man on the receiving end is non-negotiable.
