Secret Sex Room

Hikaru's got a problem that only his long-time friend can solve! Newly single, Hikaru confides in Shinori how hard bachelor life has been since he was dumped. Because with no outlet, his body is pent-up from a lack of exercise! Shinori, also in a sexless marriage ever since having her daughter, jokingly offers to help ease his tension, which Hikaru joyfully accepts. To discharge all that thick energy, Shinori starts a new secret club where they can "exercise" whenever they can, but their time together isn't enough.

Shinori knows some other high-spirited women who'll be more than willing to wear his batteries down to zero!
