Description: My stepsister and I were on vacation with mom and dad. They went down to the pool and her and I stayed in the room. Next think you know she's asking me to rate her new bikini when she took her towel off and I saw her big juicy ass in a G-string. I couldn't resist to get a hard on. She saw it and got immediately horny and started slobbering all over my cock, and boom that's all it took. We fucked for a while before mom and dad came back to the room. Stepsister is a super slut. We're gonna do it again for sure.
