Shunsuke, attempting receptive sex for the first time, visits what appears to be an oil massage parlor—but in reality, it's an illegal establishment specializing in lewd acts. Inside, a handsome esthetician lays Shunsuke face-down and begins an oil massage. Gradually aroused, his blood rushes to his groin, swelling with each stroke. Having abstained for four days, Shunsuke's cock starts throbbing obscenely under the treatment. Unable to resist, the esthetician abandons professionalism and gives Shunsuke a blowjob. Oil is then slathered onto his ass, followed by finger penetration. His anus is thoroughly massaged, slick and wet as fingers stir inside, preparing him for full anal stimulation. Shunsuke cries out, "Damn, my ass feels amazing!" Completely reprogrammed, this straight guy becomes a regular at the shop.
