Creampie incest mother and child humiliating copulation

I broke up with my husband 12 years ago. I took in the only son I had with my estranged husband, and the two of us have worked hard together. There have been many difficult times, but I have turned down all offers of remarriage out of concern for my son. To be honest, I'm also a woman, so there were some lonely nights. At times like that, I used to comfort her alone. One day, when I was masturbating as usual, my son caught me. And then my son attacked me, his mother.
