MUSUME-042123_01 How girls work: Physical examinations with beginner students

Nakamura Noriko, a student with wide, sharp eyes, appears in Onna no Shikaku. Noriko has silky straight black hair and a neat and tidy appearance, but her pussy is completely shaved. We place a ruler over her pussy and measure its size. We also measure her cute nipples with the ruler. After taking a good look at her vaginal temperature with a thermometer and her vagina with a speculum, we give her a blowjob, insert a raw penis, and have creampie sex. So, how will her size change after sex?
