My wife and her mother live together in a two-person household. I married my wife in a sort of crash-the-party way. My wife has always had little sex drive, and even when I try to initiate, she rarely responds. Today, after being rejected again, I left the room in a bad mood. I noticed faint breaths leaking from my mother-in-law's room and couldn't help but peek. Since we started living together, I've heard her breaths many times, but this time I couldn't hold back and ended up entering her room. My mother-in-law was surprised and said no, but since my body was already sensitive, I let her touch my rock-hard cock, and despite her confusion, she listened to what I said. The next day, I couldn't stop thinking about my mother-in-law and desperately wanted to have sex with her. So, I left work early and timed it so that my wife was out of the house before returning home. As I secretly watched my mother-in-law cleaning, she sighed deeply and wriggled her body. I immediately embraced her and asked if she couldn't forget what happened yesterday. She said no, stop, but opened her body to make it easier for me to touch her. I forcefully inserted myself into her wet vagina, and she smoothly accepted me, tightly gripping me. My mother-in-law, who said we should take it slow because it had been a while, had a lewd expression on her face.
