Stepsister Brianna wants me to help her choose outfits. The thing is, she wants to change in front of me... I didn't think it was very appropriate, but she convinced me otherwise when she clarified we are not related at all. As she is changing outfits I get super horny seeing that big ass of hers. She notices quickly how hard I got. She doesn't want me to have blue balls so she goes quickly to get some oil to give me a handjob. Again, I was taken back by the idea, but she reiterates that we are just step siblings-no relation whatsoever. Once she gets on the handjob it quickly goes into her rubbing those nice pair of tits on my hard cock. Then things get wilder, she puts oil all over her big ass and bounces it on my dick. From there,we have a hard fuck session, where she gets fucked from all positons until I cum all over her pretty face and mouth.
