At a certain hospital in Tokyo, the examinations being conducted were far removed from actual medical treatment. The specialist in anorectal medicine wore a suggestive smile as he instructed his patients to await their next appointment dates. Female patients counted the days eagerly, longing for their next examination. Amid whispers of "Sensei... no... this is so embarrassing..." the doctor's fingers slid into their loosened, massaged anuses. Women trembled from the intense, virgin sensations, their anuses crudely exposed as they became enslaved by pleasure. The scene unfolded into an erotic spectacle that hardly resembled a medical examination.
