Visiting my house, my mother's friend always caught my eye with her magnificent big ass. The monthly drinking party at home was my only chance to make a move. After bringing over some snacks and subtly seducing my mother, I finally found the right moment—until an unexpected incident occurred. Someone broke into the room, leading to sudden sex. A few days later, after an argument with her husband, Ms. Nagasawa let herself be flattered and persuaded, agreeing to just one time. They ended up enjoying sex together in my mother's bedroom.
