At the mercy of a certain trainer, "Makina" and "Momo" undress each other and wait in full nudity, kneeling. When their master arrives, he treads on their heads with his shoes on, yet their excitement only intensifies. With clips attached to their nipples and clitorises, their lewd hip movements are exquisite. The training progresses with lesbian commands, candle play, anal training, and even sex on a sex slave bicycle. As mere tools for one man's pleasure, the two constantly pursue new forms of ecstasy.
