When my wife was hospitalized after giving birth, my mother-in-law forcefully came to the city from the countryside. She seems concerned about her daughter after childbirth and about how I'm doing. I started living alone with my mother-in-law. She changes clothes in front of me, and her revealing clothes and lack of caution arouse my desire. I end up spilling my seed on my mother-in-law, but she understands and says, "What nonsense are you talking about? You're going to be a father soon. My mind can't keep up right now. Just today…" and allows me to have sex with her.
