A patient books the final appointment of the day so dermatologist Dr. Yuriha Aoi can take her time examining the skin on his cock. He makes sure he is healthy, chooses a complaint unrelated to an STI, and stays fully erect throughout the consultation. As she applies the medicine, her touch gradually becomes more erotic until it feels more like a handjob than treatment. Alone together in the examination room, he removes her white coat and the appointment turns into sex.
