GRMR-153 Human Observation: A Night Alone in the clubroom with a shy, modest busty girl who has little experience with men, teaching her the proper way to appreciate a big chest and the appeal of a man’s body.

After a party in a university club room, a man and a woman end up falling asleep. When they wake up, they start drinking together again, and the alcohol gradually leads to increasingly suggestive conversation. The woman says she has little experience with men and is not good at intimate matters, but the man insists that he can help. Her plain appearance hides a striking figure, and as his excitement grows, they begin getting carried away in the club room, even though someone could come in at any moment.
