GRMO-203 Human Observation A big-breasted erotic woman who becomes a training ground for a male friend who started working in a sex industry for women, and inadvertently craves pussy sex and asks for her friend's dick.

The two seem to have an open friendship, even talking about how the woman has recently become addicted to adult entertainment for women. It seems that the man started working as a woman, but was not popular, so he came to her for advice. While practicing the massage, the two of them came into contact with each other's skin, and it became a bit uneven. It gradually escalated, and they even practiced real acts that would be inappropriate for a woman's style.
