OMG why did I do that? She'll never forgive me, but I couldn't help it. The guy suddenly stood behind me and put his hand in my panties, how can I resist? I was just too horny and my stepsister's husband used it mercilessly. He had been keeping an eye on me for a long time and was constantly staring at my huge boobs, even then I knew he wanted to fuck me and now he finally managed to seduce me, even while my stepsister was upstairs. We fucked across the house and my big natural breasts rocked in time with his bumps, I just hope she didn't hear us or maybe I did?
