It's been a week since I took care of my brother-in-law Yasuyuki from my husband's parents' house. My wife, Riko, was a little overwhelmed by my brother-in-law, who was a little withdrawn. For the past few days, I've been masturbating and letting go of my feelings because of the stress I've been taking care of without knowing it, but Yasuyuki witnessed it all the time... Riko, who was overwhelmed by her husband's absence, was easily raped. From that day on, Riko's shameful days began as she couldn't talk to anyone and was raped by Yasuyuki's orders.
