Mixed-gender health checkup 2020, peak summer, featuring Mio. Beautiful Mio, who looks stunning in her school uniform, appears with an adorable ponytail that radiates innocence and good upbringing. During the physical examination, she hesitates and feels shy about undressing, causing the male students to get extremely excited. A seasoned nurse scolds, "Boys, stay quiet! Keep your social distance!" When pressured with, "Don't you want to get into a good university through recommendation? Your evaluation will suffer if you don't cooperate!" she stammers, "I-I'll undress myself..." but still resists, eventually being forcefully stripped. During the body check, her underwear is pulled down as she undergoes a spinal examination, enduring the scrutiny of onlookers with a touching sense of vulnerability. During the breast cancer screening, she turns her face away in distress as her breasts are palpated. As her breasts are squeezed and her nipples pinched, hidden pleasures begin to awaken within her. Then comes the vaginal examination—her newly grown pubic hair and glistening, slick pussy on full display. With a thermometer inserted into her vagina and a speculum used for internal inspection, she suffers intense humiliation in front of a crowd of men. She's then made to crawl on all fours for an anal check and pinworm examination, whispering, "I've never even shown this to my father..." Her embarrassment is evident, yet arousal is clearly building. A finger is inserted for cervical cancer screening, and she struggles to suppress her moans. Even as she pleads, "Stop, sensei... if you put fingers inside, I'll break apart," she loses control, sweating and blushing intensely. As her cervix is examined, she climaxes from fingering, her anus and pussy fully exposed. After squirting, she undergoes final vaginal irrigation with a douche. The nurse instructs, "You have to wash your labia properly, or it'll stay dirty," and adds, "Ask the nurse how to clean yourself properly before you go home."
