My sister's friend's big ass gets taken advantage of by her stepbrother

My sister's friend is a total hottie, and I've been eyeing her luscious ass for a while now. She's got this petite frame with a juicy ass that just begs for attention. One day, I decided to make my move and hit that ass. I knew her stepbrother would be home, so I had to be quick and sneaky. As soon as he walked in, I wasted no time and started riding his monster cock. The risk of getting caught only fueled my excitement, making the experience even more intense. I hope my ride satisfied him because his cock felt so good inside me. I hope he doesn't tell my sister because then it would be a whole other ball game. But let's be real, who would blame him for taking advantage of such a hot ass?.
