URVRSP-581 I’m secretly having an affair with my brother’s wife, who lives with us, and whenever I find a chance, we sneak away for intimate moments. Yoba Mami

Two years after getting married, I moved to Tokyo with my older brother and his wife after his job transfer. My sister-in-law, Mami-san, has a bright personality and has always been friendly with me. But Mami-san and I have a relationship that we can’t tell our partners about. It’s an affair under the same roof.

Since I mainly work from home, we spend a lot of time together. She was the one who made the first move, and we discovered we were very compatible, so we kept seeing each other from that day on. We can’t let anyone find out, even though her husband and my wife are right nearby. That secrecy has started to excite us both, and today too, we keep looking for chances to be alone together.
