DASS-388 | I don't listen to what my butt says. The temptation of a plump older sister who is dominated by her big butt and cannot resist her instincts. Kana Morisawa

Kana had a secret that she couldn't tell anyone. Her own instincts manifest in the movement of her butt, and when her hoop comes off, her consciousness is dominated by her butt, contrary to her own will. One day, a man moves in next to her and falls in love with her butt at first sight, and Kana's consciousness is taken over by her butt.
