OFKU-080 While my stepfather wasn't looking, with my daughter-in-law's mother... Kyono Mirei (44)

My wife went on a two-night, three-day hot spring trip with a friend. My mother-in-law is 44 years old and in her prime. She has youthfulness and charm, making her very feminine and attractive. My mother-in-law has a slim figure but with just the right amount of curves; I've had lustful feelings for her... My wife's family treats me like their real son. However, I have impure thoughts about my mother-in-law and want to make her interested in me somehow…
