My wife is pregnant and is about to give birth. We and my mother-in-law, who live together, and three of us went to the hospital. However, there was no sign of birth yet, and my mother-in-law and I returned home. At dinner, my mother-in-law said that it was still okay, and the two of us had a drink. When I said that I seemed to be doing something wrong, my mother-in-law kissed me when I tried to do something worse. My mother-in-law's kiss is disgusting but stimulating.
