It took her a while to figure it out, but she finally got me. Having my stepmom next to her always made her hard on me, but being able to see her big ass while she was laying down made her unable to help but jerk me off. She caught me and I tried to hide it by covering myself, but she had seen me and that made me even more horny. Finally the bitch was the one who looked for my cock to jerk me off, but it didn't take long for her to put it in her mouth. She sucked me off and then I put it in her pussy. My slutty stepsister liked that, in the end I went to cum and she decided to put it in her mouth so that when she ejaculated she could taste my cum..
