Hey can you help me out quick? I'm going to a party and I need help picking a dress.. and since you're my step brother I figure you'd give me an honest opinion. I undress in front of you and show off my first dress.. then I notice you're hard.. omg! I did that? Your sis got you hard? Well then.. how about you take it out and stroke it for me. I tell you I'm going to be slutty at the party, no panties or bra.. all the guys are going to want to fuck me. This gets you even more turned on.. knowing your sis is super naughty. I tell you to cum while bent over on the bed showing you my pussy and ass!
