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 family 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 a cock and we are only step family 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.
