Doctor Anju and nurse Aya Sakuraba welcome disgusting men every day for medical examinations at their clinic. Among them is a man suffering from a rare condition known as "Tan-Tan Disease," said to cause both tongue and genital length to shorten with age. For these men, the daily measurement of tongue and genital length is a nerve-wracking experience. Additionally, a male AV actor visited the clinic after being criticized by a female performer for his poor tongue-kissing skills, leaving him deeply shocked. Doctor Anju and Aya Sakuraba use their lewd, skillful tongue techniques to heal and satisfy them all. This clinic, visited daily by men with strange ailments and insecurities, has become a place of humor and healing.
