Living with my mother-in-law and wife, i couldn't take my eyes off her. One day, i saw her sweating and pleasuring herself alone. That sight stayed with me. One night, my wife tried to initiate sex, but i was too tired to respond. My mother-in-law overheard our conversation and confessed that she couldn't stop thinking about me. She quietly led me to her bedroom, saying it would only be for today, just once.
