A J● relaxation parlor located in Ikebukuro. The shop officially enforces strict rules: no ejaculation, no touching. However, an unexpected reality exists—every girl working there negotiates private, off-the-record services behind closed doors. A popular urban legend claims, "Cute J● girls probably do backdoor services all the time," and we decided to go undercover to verify its truth. Our subject was S-chan (pseudonym). We managed to gather information without her knowledge. The result? She frequently performs private extras. What followed was not only shocking but also strangely amusing. After intense, intimate contact, she even allowed creampie ejaculation. It turned out to be an extremely satisfying experience.
