My wife and I were worried about something. In the middle of that, I was surprised by my mother-in-law's sudden visit. Then my wife appeared from the back with a slightly lonely face. My wife had called my mother-in-law to ask her for something. My wife told her that she was infertile and asked my mother-in-law if she could be a surrogate mother. My mother-in-law was surprised and asked me if it was okay, and when I nodded, she thought for a moment and agreed for the sake of our daughter. I checked my mother-in-law's health and ovulation date, and finally the day came. I asked my mother-in-law if it was okay, and she quietly nodded, and my wife left the room. I caressed my mother-in-law nervously, and although it was an awkward act, I released my sperm inside her. After that, I continued making babies with my mother-in-law almost every day. I think it was around the third time that my mother-in-law changed, and she tried various things to please me, and sad moans began to leak from her mouth. However, my mother-in-law still had a sense of obligation and a business-like atmosphere about the act. So I made the following suggestion to my mother-in-law. Since we were going to have a good time, I thought it would be easier to get pregnant if we had fun. After that, we pursued each other like lovers. My mother-in-law greedily pursued me, as if her previous behavior was a lie, and I released a large amount of sperm into her. A few months later, my mother-in-law gave birth to a child, and my wife held him happily. The happy time passed, but I could not forget my mother-in-law's body...
