After marrying my wife, my father-in-law passed away. To help my mother-in-law who lives alone in the countryside, we decided to live together. I found a job in the countryside for this purpose, and my mother-in-law was very happy. We were living a smooth life... But then, a problem arose. I couldn't get an erection with my wife anymore. I hadn't been aroused by her for months. Instead, thinking about my mother-in-law made me hard. I couldn't tell my wife about this, so I spent my days imagining being with her. One day, my mother-in-law was napping on the sofa. A mischievous thought crossed my mind, and I started touching her body. I touched her breasts and ass, but she didn't wake up. I became bolder and started playing with her. When I removed her underwear, a lewd scent filled the air. I buried my face in her crotch and started licking her passionately. Eventually, she woke up and scolded me, but I pinned her down and forced myself inside her. I was so excited to have sex with my mother-in-law that I couldn't hold back and came inside her. Overwhelmed with guilt, I quickly retreated to my room. That night, I couldn't sleep due to the guilt and went to the living room. I peeked into my mother-in-law's room and saw her pleasuring herself. After a while, she reached an orgasm. I embraced her and got lost in the act again. However, my wife saw us...
