Rei Aino, a beautiful woman who gained attention as Miss Campus, is attacked by a stalker while returning from shopping and wakes up in a prison cell. Surrounded by grinning men in black suits, she is forced to drink a powerful aphrodisiac designed to strip away her reason. Immediately afterward, Rei is subjected to repeated forced orgasms, loses all sense of self, and is chained to a toilet, eagerly licking the men's filthy feet and anuses. Used like a toy in gang rape sex, she is drenched in massive amounts of semen, growing increasingly depraved with each assault, ultimately depicted as completely dominated.
