Reservations are flooding in and there are many repeat customers!! The busty massage parlor that everyone is talking about actually exists!? She was supposed to be examining and treating men who were suffering from dysfunction, but instead, her penis got so big that it made the men embarrassed. The therapist, Riho Hoshiyama, is highly praised by the store manager, who says, "Although she's new, she has the service and technique to attract more and more repeat customers every day." In addition to her warmth and devoted service, her biggest charms are her "sweet hands," which are fingertips that make you feel tingly just by touching them, and her large breasts that stick out so far that you can't see what's underneath. However... it seems that she has a "secret treatment" that doesn't end there!?
