My wife is pregnant and will soon give birth. She is full of anxiety as it is her first birth. Perhaps knowing my wife's anxiety, my mother-in-law has been supporting her. One week before the due date, my wife went into labor. In contrast to my wife and the panicked me, my mother-in-law was very calm. In the end, it was decided that the baby would not be born that day, so I left my wife at the midwife's clinic and went home with my mother-in-law. Then my mother-in-law invited me to have a drink together. I told her that I felt like I was doing something naughty, and she kissed me saying that she would try something even naughtier. My mother-in-law's kiss was lewd but stimulating, and since I hadn't been with my wife for a while, I got an erection right away. Then my mother-in-law happily took my dick in her mouth and sucked it slowly. I couldn't hold it in and ejaculated, so my mother-in-law sucked my dick again. Then my wife called. I answered in a hurry, but my mother-in-law buried her face in my crotch again and started licking it with a happy look on her face...I never knew my mother-in-law was so lewd... Even though my wife was about to give birth, I was drowning in my mother-in-law's eroticism...
