Aika Yamagishi who is messed up by a beautiful older sister in a state where she can not move

Yuka Yamagishi, a beautiful and famous older sister, is in a situation where she needs a fake boyfriend to avoid a blind date set up by her parents. She asks her younger counterpart, Aika Yamagishi, to pretend to be her boyfriend for three days and two nights. As they spend more time together, Yuka takes advantage of Aika, tying her up and making her watch as she masturbates, and eventually forcing Aika to perform a blowjob on her. The central kink of this movie involves coercion, manipulation, and non-consensual acts between the two sisters, exploring themes of power dynamics and control within their twisted sibling relationship.
