Open 365 days a year, 24 hours a day, easing the pain of any anus! (Offer limited to beautiful girls.) The main character is a doctor with a childish face. His specialization is girls' buttocks, but girls don't want to be examined by a male doctor. So he writes a sign that the clinic is run by a female doctor, and the first girl shyly opens the door.
