A gay bar in Shinjuku Ni-chome has a secret menu that only a select few customers know about. It's making customers cum with your hands and mouth! In reality, you can make more money by using your ass as well, but Yoshino, the waiter, is afraid of sex and doesn't want to do it... But then his favorite customer, Mikado, who requests him every week, starts targeting his ass! "Does it really feel good?" -- Will Yoshino finally give in...?
