My wife and I finally got our dream home, even though it was small. My mother-in-law, who lives in the countryside, came to visit. However, we couldn't prepare a guest room, so my wife suggested that we all sleep side by side. My mother-in-law was wearing a chemise as a pajama. I was a little excited by the sight of my mother-in-law. However, I couldn't look at my mother-in-law with such a lewd gaze, and I couldn't sleep on the first day. The next day, I asked my wife to help me out, but she told me to do it myself. With indescribable feelings, we all went to sleep side by side. In the middle of the night, I was surprised to wake up with a strange feeling in my lower body. My mother-in-law was licking my crotch and stroking me. It seemed that she had heard my conversation with my wife, and I felt sorry and asked her to at least make me feel refreshed, so I let her do as she wanted and ejaculated into her mouth.
