My ass must win the contest! Savannah Fox - Taboo Handjobs

You have to help me with something very important and you can't say a word of this to our parents. Remember that time when I caught you and your girlfriend in your bedroom and I didn't tell step-mom and step-dad? Well, there is a best ass contest going around campus and I need your help so I can win. You owe me some help for not squealing on you about the girlfriend incident. This is what stepbrothers are supposed to do, help their step-sisters. All I need you to do is take a few pictures of me so I can post them to social media. All this attention on my ass will be sure to get me the win plus maybe even a boyfriend. Eww, what is that happening in your pants? Are you getting turned on by all this ass talk and photographing my big round butt? This is certainly not what I expected to happen. You should probably rub that out real quick before you leave my bedroom just in case you run into our parents in the hall. You're too embarrassed to rub in out in front of your stepsister?
