Ridden off the stepsister's horny friend

My stepsister always had the better guys at sex, I only got the 2nd choice, but that was about to change this time. I was on vacation, my stepsister wasn't and that Dave was always horny and always looked at me horny, I knew now or not at all. Outside in the meadow when the weather was nice, he first licked my pussy wet so that I could then saddle him up nicely and rode his hard thong off him. Oh yes, what a hard cock Dave has, you forget everything around it. First I ride him off nicely to then be taken doggy style and blow him until he spits his sperm on my big firm tits
