Takeshi dates Momo, a busty masochist from the same university. He is gentle in everyday life, but sex brings out his dominant, sadistic side, and his demands keep escalating because Momo obeys every order. He makes her suck him while she cooks and relentlessly toys with her pussy using an eggplant. Craving even stronger stimulation, Takeshi strips, blindfolds, and restrains Momo, then calls over friends to torment her with three cocks.
