A new video of the "joint ward housing complex" that is a hot topic among real enthusiasts. "Uncle" who repeats mischief and sexual activity to multiple tanned shaved girls who are curious about sex. The off-limits housing complex, which has been decided to be demolished, is a secret playground for girls. An uncle who repeats obscene acts appears there as a play that only adults know. Even though they don't understand sexual activity, the girls who are initially confused as "doing something they shouldn't do" feel an unknown pleasure and become prey to their uncle one after another.
