She's just started an underground part-time job on weekends. One day, as she headed to the changing room as usual, the store manager instructed her to go to a different room. Inside stood someone dressed in a white coat, looking just like a doctor. Apparently, due to regulations related to the adult entertainment law, she must undergo a health check once a month. Sitting on the examination bed, she removes her bra and takes off her panties, then follows instructions to spread her legs and close her eyes. Next, she gets on all fours as her anus is carefully examined. Then she's told she must masturbate for a bodily fluid test. Though slightly surprised, the awareness of being watched excites her, causing more fluids to leak out than usual. What kind of health check is this, exactly?
