Mom had just sucked my cock until I came all over face.
Once I finsihed, I knew I wasn’t going to down like usual. So I took this opportunity and picked mom up and pushed her onto the bed. I think she might have thought I was going to eat her out from behind, but when she felt my cock press against her wet pussy I heard her gasp “oh shit” followed by an “oh my god!” as I entered my mother completely.
I slowly began thrusting my cock in and out. And I could feel my mother begin to press back into me. We had finally crossed the final line between a mother and her son.
