[HMN-889]

I became a raw creampie practice dick for my older sister and her friends: Karin Kitaoka, Yumi Nijimura, Shiori Yorimoto

Three girls attending an all-girls school were starving for men. They got excited talking about masturbation like male college students. "Shiori, you have a younger brother, right?" They got worked up wanting to see her little brother's dick, and under the pretense of having him model for an art homework assignment, they made him strip naked—only to find he was unexpectedly well-endowed!! Their horniness escalated, and he became a raw creampie toy for his older sister's friends. "Huh? Older sister??" After the two left, even his horny older sister attacked him!??
