GRMO-203 Human Observation - A busty pornographic woman becomes the training ground for a male friend who has started working in the female sex industry, and unintentionally craves vaginal intercourse and demands her friend's penis.

The two seemed to have an open friendship, even discussing how the woman had recently become addicted to female adult entertainment. It appeared the man had started trying to be a woman but wasn't accepted, so he sought her advice. During a massage session, their skin came into contact, becoming somewhat uneven. Gradually, things escalated, and they even practiced some realistic movements unsuitable for a woman's style.
