A new video from the "publicly operated public housing complex" that is a hot topic among real-life enthusiasts. An "old man" repeatedly plays pranks and has sex with several tanned, shaved girls who are Kokoro about sex. The off-limits housing complex, which is scheduled for demolition, is the girls' secret playground. An old man appears there and repeatedly performs obscene acts, claiming that it is a game only adults know about. The girls are confused at first, not realizing that it is a sexual act, thinking "I'm doing something I shouldn't do," but they soon begin to feel an unknown pleasure and one after another become the old man's prey. *There are no performers under the age of 18 in this work.
