I am your step sister and you are waiting for me in my room. Mom and dad think I am such a good girl but you know I am secretly a party girl and a slut. You catch me coming in wearing a slutty tight little dress with no bra or panties. I try lying to you and covering up, insisting I never went anywhere. I confess to going out and beg you not to tell mom or dad. I offer you money and tits...but I know what you want. I lift up my skirt, revealing that my pussy is already filmed with cum from at least one guy at the party I was at. You always knew I was a slut. You watch the cum drip from my pussy as I shake my bare ass for you. Then, I hop on your dick and ride you. I check back at you to make sure you are enjoying yourself and that you won't be telling our parents. The other guy's cum is still dripping out of me when I go to insert your cock in my tight little pussy. I ride you until you cum inside me too, and all the cum is just pouring out of my slutty little pussy. Please don't tell mom and dad I am such a slut!
