ZOZO-049 Kanna Shiraishi's Anal Examination at School

During a mixed-gender health checkup, Kanna Shiraishi, a class representative, is examined anally. She confesses to masturbating twice a day, and her pale skin shows red bra marks. She squats, embarrassed, as her pink anus is shown on a monitor. A finger is inserted for a rectal exam, and she feels a strange sensation. Various instruments are used to check her sphincter, and she climaxes in shame. No anal sex is included.
