A popular okonomiyaki restaurant in Tokyo has a rumored shop girl who gives erotic services to regular customers she gets close with! Hearing the rumor, I visited repeatedly and eventually built relationships with two beautiful female staff members, successfully having sex with them. The shop is run by a cheerful, radiant 20-year-old girl and an elegant, gorgeous 30-year-old older sister type. An AV actress goes undercover to expose their hidden, sensual sides. The older sister-type employee boldly calls customers into the bathroom, lets them touch her body, and gives blowjobs. Meanwhile, the fun-loving 20-year-old easily agrees with a laid-back "Sure, it's fine," readily engaging in sex.
