I planned a hot spring trip to cheer up my mother-in-law, who was still depressed several years after her father-in-law passed away, and to enjoy some relaxing mother-daughter time. - My mother-in-law is still young and beautiful, and I have always wanted her to become healthy. - After arriving, I immediately went to the bathroom. - When I saw my mother-in-law after taking a bath, I was shocked. - I was surprised at how cute and sexy my mother-in-law was, with her slightly pink face and her big breasts peeking out from her yukata. - After dinner, I wanted to have a light drink, so I received a drink. - My wife, who doesn't have a strong tolerance for alcohol, went to bed first and was alone with my mother-in-law. - My mother-in-law stares at me with moist eyes. - That's when I fell in love. - When I put my drunk mother-in-law to bed, she called out my father-in-law's name and hugged me. - When my soft lips touched my sanity, my mind collapsed. - My stepmother realized that it was me and not my stepfather, but I couldn't stop her and crossed the line. - This is the story of my mother-in-law's first night with me. - I'm having fun with my mother-in-law so that my current wife won't find out. - Because a mother-in-law is much better than a wife.
