What if you had an older sister like this? Mao Kurata plays an exhibitionist older sister who will stir up your fantasies! Whenever the married older sister has a dispute with her husband, she stays at her younger brother's house and even relieves her stress by having sex! She always wanders around the house dressed provocatively, and it's natural for her to give him a blowjob when she wakes up. She even forces him to give her an erotic massage in see-through loungewear, and even sneaks in and has sex with him when his girlfriend comes over! We bring you a completely subjective view of a dreamlike cohabitation life!
