Story

The Yosugara siblings (elder brother Hikaru, younger sister Mioto) and the Sugihara siblings (elder brother Hakuro, younger sister Akimi) are childhood friends. Mioto and Hakuro are dating, and today too the two are absorbed in fierce sex in Mioto's room. Pressing his forehead to the wall and watching them through a peephole, breathing hard and rubbing his own crotch, was the elder brother Hikaru. Hikaru ejaculates at the same moment the two of them climax. Then, curling up on the floor, he mutters, "Mioto..." Hikaru was in love with his younger sister Mioto. At night, alone in bed picturing Hakuro and Mioto's sex, Hikaru hears a knock on the window glass, and Akimi climbs into his room. Akimi says she has something to consult him about. The matter is that she wants his cooperation in breaking up Hakuro and Mioto. Akimi, too, was in love with her elder brother Hakuro. When Hikaru refuses to help, Akimi says, "Even though you're the same as me..." and "I saw you peeping on the two of them having sex... and doing that." Enraged, Hikaru pins Akimi down. On the condition that she keep quiet about the relationship he forced on her, Hikaru agrees to help Akimi...
