I can't believe I have to stay home and babysit my little brother, UGH. All my friends are going to the movies, but I'm stuck at home because of you. Uh, why are you staring at me like that? You're my little brother, you aren't supposed to be checking me out. God, I didn't know my little bro was such a fucking pervert. Well, if you like this so much, then I'm going to tease you. Stroke it for your sister. I want you close to orgasm. I want you to cum in your big sister's mouth.
