Our parents went out of town for the weekend and Courtney and I figured we'd go to a house party instead of being cooped up. It was a fun time, Courtney looked so hot in her dress and all the dudes were trying to hit on her, but I wasn't going to have any of that. I kept her close to my side and made sure the horny bastards wouldn't be getting ANYTHING from my little step-sister. We arrive home, I head to my bedroom and in comes tipsy Courtney flopping on my bed tits falling out and all. Maybe this is my chance to fuck her. I lean in and kiss her. It's on now, she pulls out my cock and starts sucking. She is amazing! I love watching the way she sucks and takes me all the way down her throat. She gets on top of me and rides me, leaning back so I can see my cock slip in and out of her tight pussy. I need to pound her so she lays back and moans while I fuck her hard and crazy. My little step-sister's pussy feels so tight and wet. I can't believe it's even better than Iv'e imagined.
