The younger generation is seeing an increase in cancer. 'Please! Cooperate with the government's investigation,' they said, and a mixed-gender anal health checkup was organized. However, even if it's an examination of the anus or rectum, female students would have resistance... So, to alleviate the students' anxiety, the new English teacher, Mr. Shinami, was asked to undergo the examination first. Gently palpating the lymph nodes. Sticking out your butt and doing squats. The embroidered panties are sexy. The waist, buttocks, no lumps, feels good. Well, shall we take a look at the anus? Oh, there's bleeding. 'Wai... in front of the students... it's embarrassing.' 'Get on all fours. You can check for yourself on the monitor.' Counting the anal wrinkles, covering in shame with your hands. But if you resist, they'll do it forcefully! Covering with your hands. If you resist, they'll do it forcefully. After thoroughly checking for polyps and abnormalities in the sphincter, a special device (live penis) is used to examine deeper inside! 'What is this... Ugh... Ah... What is this?' 'Shall we check the birth canal at the same time?' Simultaneous dual-hole stimulation! Using another special device to change angles for re-examination. 'Move your hips and feel for any discomfort? You're quite skilled!' 'Wa, is my body okay...?' Yeah. It's fine. Finally, medication is injected into the depths of the uterus and it's over. Everyone, did watching Mr. Shinami's examination alleviate your anxieties? ※In this work by Shiraishi Kanna, anal sex is not included.
