DASS-388 My ass doesn't listen to me. The temptation of a chubby older sister who is dominated by her big ass and can't resist her instincts. Kana Morisawa

Kana has a secret that she can't tell anyone. Her instincts are expressed in the movement of her butt, and when she lets go, her butt takes over her consciousness against her will. One day, her butt falls in love at first sight with a man who moves in next door, and Kana's consciousness is taken over by her butt.
