I hid in the closet to prank my step-sister. Instead, she caught me and surprised me with dirty talk and masturbation. She's curvy with natural tits and a big, fat ass. We had wild sex, and she rode my monster cock hard.
I decided to play a prank on my step-sister and hide in the closet while she was changing. My plan was to scare her, but she surprised me by getting up from the bed and starting to masturbate. This was not what I expected, but it turned out to be a very hot turn-on for me. She started talking dirty to me, telling me to come and fuck her. I could not resist her and I got hard instantly. She was very horny and ready to get fucked. I started to fuck her hard and she loved it. She was moaning with pleasure as I was fucking her. She is a very sexy girl and her fat ass is amazing. I enjoyed fucking her and I came inside her. She is not my sister but she is very hot and I would love to fuck her again.
