My friend's mother has a strange sense of chastity.

Okuyama is the first time he goes to Yuichi's classmate to visit him. He casually crosses Yuichi's house, but there is a sight that makes you doubt your eyes! When I opened the entrance, I found <menstruation products> casually placed. Yuichi's mother Yukiko greets Okumura wearing no bra. Okumura is a little confused by the extraordinary family environment, but afterwards, seeing Yukiko masturbating openly, she realizes everything. "Yuichi's mother's chastity concept is strange."
