Twenty-five-year-old Rino Sakai was once an active model and is now married to an older successful businessman. Although she thought she would live happily thanks to her wealthy husband, in reality, he continued his wild affairs even after marriage, leaving Rino constantly feeling lonely. One day, she heard from a friend from her modeling days that women's-only brothels were extremely erotic, so she decided to try it for the first time. Initially nervous, Rino's suppressed desires exploded the moment she entered the hotel. Her erotic switch flipped ON, leading to a forbidden bareback experience with slick, oily lotion covering her body. She experienced intense, genuine orgasms, convulsing from overwhelming pleasure. In the end, she was thoroughly creampie-filled, making it a deeply satisfying experience.
