I'm living as a son-in-law at my wife's parents' house. Both my mother-in-law and wife are kind, and I'm grateful every day.

Unable to sleep, I went alone to the living room. Then, my mother-in-law woke up. Seeing my face, she asked what was wrong, and I ended up telling her about the lack of sex with my wife. My mother-in-law looked at me sadly and said, "That girl is sorry, if you don't mind, it must have built up quite a bit," as she touched my crotch. Saying today was special, she took my dick in her mouth and sucked on it. My mother-in-law's slurping fellatio was exquisite, and I came immediately. Although I felt relieved, after such a long dry spell, I couldn't help but want to have sex with my mother-in-law, so the next day, when I saw my wife leave, I pounced on her…
