RS-287 Movie – Blue Thong Bodysuit
Mina dons a blue thong bodysuit over black tights. She is bound with thin red rope at multiple places around her elbows and sits straddling a bench, a tight crotch-rope digs deep as she moves around, which is tied off to the rear of the bench so any forward movement bites deeper. She is gagged in a harness ballgag.
