Adult track-team role-play. The cocky team ace who mocks her teacher is imprisoned, dressed in crotchless bloomers, and subjected to brutal orgasm torture with an iron hook. Vaginal pressure makes her convulse, climax, and lose control of her bladder again and again. Even when she begs for it to stop, concrete weight is added so the steel rod pounds deep inside her, pushing the awakened masochist through relentless forced orgasms.
