I got married and live with my wife and mother-in-law. I'm in a situation like Masuo-san. I get along well with my wife, but she doesn't seem to like nighttime activities, and we haven't had sex for a year. I tried to ask her for it again, but she refused because she wasn't in the mood. As I headed to the living room feeling a little irritated, my mother-in-law asked me what was wrong. I hesitated for a moment when she said we're family, but I told her that we haven't had sex. My mother-in-law was surprised, but she looked at me and said, 'I'm sorry, my daughter, but if I can help you feel better?' My mother-in-law is fair-skinned, has big breasts, and I've always wanted to squeeze them from behind, but when she said she could help me feel better, I didn't know what to do. She smiled and licked my nipple, then grabbed my erect penis. She said it would be a secret from my wife, and the blowjob felt so good that I came in no time. I did feel better, but I still felt a little empty, and I was tempted to play a prank on my mother-in-law.
