Nana Yagi arrives in Shinjuku's Kabukicho district for her first genuine report on the sex industry. She explores an adult fantasy club, submissive men's service, an outcall host massage, and a swingers bar, taking turns acting as both worker and customer. The sexual atmosphere gets her so horny that she asks amateur participants for full sex, going at it without the venues' permission. Seasoned customers pound her with their amateur cocks until she cums again and again. Where will this fearless, hands-on investigation with her pussy lead?
