My husband and I returned to my wife's parents' home for the first time in a while. My parents-in-law welcomed me warmly. During the gathering, when my father-in-law started saying that he wanted to see his grandson, my wife suddenly became displeased and left the table. I told my confused parents-in-law that my wife was refusing to spend the night and that it was no good even if I invited her. I felt sorry for my stepparents' disappointment.

It was getting late at night, but my father-in-law did not return. I made up my mind and headed to my mother-in-law's bedroom. He gently lifts the bedclothes of his sleeping mother-in-law and caresses her. Before long, my stepmother's private parts began to make a clicking sound. My mother-in-law wakes up and is surprised. I couldn't hold back anymore and inserted it into my mother-in-law as if to attack her...
