Mixed male and female anal health checkup at a co-ed school! "You saw the teacher's test first, didn't you? You don't have to worry about anything, right?" Kanna, the class representative, is the first student to receive a diagnosis. She confesses that she has a bowel movement twice a day, and when she is shirtless, her skin is so white that the marks on her bra look red! "Don't look at the boys..." I squat while enduring her gaze.You are quite shy! "Isn't it important to check it yourself?"The super beautiful pink anal is fully visible on the monitor. "If you haven't seen it, let's see it. If you move like that, you won't be able to see the anus..." Insert her finger for a rectal examination. "Ugh... I have a strange feeling..." "Everyone is like that at first."The back of the anus is also shown on the monitor, various instruments are inserted, and the condition of the sphincter muscle is examined... Come on!Boys!Don't peek through the partition (laughs) *This work by Kanna Shiraishi does not include anal sex.
