My son's wife, Hoshina-san, is a very attractive wife. I ended up having forbidden feelings for such Hoshina-san. Whether she knew it or not, Hoshina-san started to seduce me. When my son goes to work, she teases me with body touch, making me uncomfortable, and that escalates to the point where she shows me masturbation and even sex with my son... My reason was about to reach its limit...
