Three girls attending a girls' school were starved for men. They get excited talking about masturbation like male middle school students. Shiori has a younger brother, right? They get hyped wanting to see her little brother's dick, and under the pretense of having him model for an art homework assignment, they make him strip naked, and surprisingly he has a big dick!! Their horniness escalates—and he becomes a toy for his big sister's friends, used for raw insertion creampies... 'Huh? Big sister??' After the two leave, his horny big sister also attacks him!??
