Mông của tôi phải giành chiến thắng trong cuộc thi! Cáo Savannah

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 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.
