Mijn stiefmoeder gaf me een prachtige aftrekbeurt voor huiswerk

My sisters step-daughter needed some help with her college math homework and I needed some help with my cock. So it worked out quite well. Ever since my step-sister married her husband I have been rock hard for his step-daughter. She is young and slutty, exactly how I like them. I could tell she liked me and was eager to show me as much skin as possible without incriminating herself. I mean, I am almost old enough to be her step-dad.
