Rough Sex with Busty step-mom in Tights

Have you ever had a muscle jammed because of an unsuccessful movement? That's what happened to me... fortunately, my step-son was at home and was able to help. He stretched my ass very well and, (don't tell my husband) climbed into my pussy with his fingers. I immediately got wet and I didn't care that I was his step-mother and just began to enjoy how he used me.
