I was horny. My stepbrother masturbates all the time and it s so annoying. This time I decided to give him a taste of his own medicine and I started masturbating right in the living room. when he walked up on me though, I decided it would be a lot nicer to just let him fuck my pussy. Masturbating doesn t feel nearly as nice as a cock and I am only his stepsister after all. It took a moment to convince him but with my legs open all splayed out he didn t have to think about it for long.
