One day, a sudden mixed-gender health checkup is held at the office. Set in 2020, this features Horikita Wan, the beloved new female recruit. Popular among her coworkers, Wan questions the presence of male employees during the examination but ends up being forced to endure it anyway, her small breasts pressed tightly against the X-ray plate as she undergoes the exam wearing only her panties. During the checkup, she playfully says things like "Make sure to look carefully, okay?" while also expressing embarrassment with lines like "Eh... looking at myself... no way..." During the anal examination, her tight, inexperienced anus is displayed on the monitor, exciting the male employees. Continuing the scene, she reluctantly submits to foot stomping, asking, "Eh, do I really have to do this?"—her awkward expression bringing humor. During the vaginal pressure test, fingers are inserted into her pussy, and as she moans "Ah... ah... ah...", she becomes increasingly aroused, eventually reaching a squirting orgasm. Her pussy is then spread open for measurement, revealing a petite size of 3.6cm. Using a speculum and CCD camera, the deepest parts of her vagina are thoroughly checked for abnormalities. After receiving an internal vaginal wash, she leaves the clinic feeling pleasured and satisfied.
