Jotaro, a freelance writer, has moved out and returned to his parents' house. On a tropical midsummer night, Jotaro spies on his younger brother and his wife, Nozomi, making love, and when they are alone together in the afternoon, he can't help but rape her. From that night, the two of them devour each other's bodies as if in a fever. Dripping sweat... gushing desire... an intense summer love affair!!!
