For seven days of complete confinement, one woman is subjected to a 5-liter enema torture, forced to continuously leak, while the other is tormented with vibrators and hot candle wax, twisting her body in pain. They are made to drink urine, gagging and choking in distress, then made to piss into a large bottle, their faces contorted in humiliation. Both are hung upside down, completely naked, and flogged with whips. Their labia and clitorises are manipulated like puppets, and they are assaulted in midair with double-headed vibrators. Through this intense training, jealousy and competitiveness awaken within them, their eyes gleaming with desire. Deep in their bodies and minds, the women come to crave not just being displayed, but being dominated. But in the end, which one will truly be chosen as the submissive?
