HMN-889 I Became the Practice Partner for My Older Sister and Her Friends — Karin Kitaoka, Yumi Nijimura, Shiori Yorimoto

Three girls who attended an all-girls school were starved for male attention. They got carried away talking about self-pleasure like a group of boys. They asked Shiori if she had a younger brother and got excited at the thought of seeing him, then used an art assignment as an excuse to have him pose nude. To their surprise, he turned out to be quite well-endowed. Their excitement kept escalating, and he ended up being taken advantage of by his older sister’s friends. After the two left, he was then approached by his aroused older sister as well.
