In this adult athletics role-play, coaches run a one-on-one lower-body training camp for female track members. During the wall-sit drill, any athlete whose shaking thighs give out drops straight onto a waiting cock. One after another reaches muscular failure and is penetrated, then pounded repeatedly in the name of building stronger legs until her lower body convulses in orgasm. The session continues at night in the communal bath, where the exhausted women are pushed beyond their limits in a small group-sex drill.
