Satisfying my horny little stepsister

I'm lying on my bed talking with a friend when my Stepsister comes into the room. I know what kind of mood she's in by two things. 1st she lights up a cigarette in the doorway and second she isn't wearing any pants or panties. She comes over to my bed and straddles me rubbing her pussy against my crotch. She tells me to take off my clothes and starts to suck and stroke my cock before I can get them all off. She lays on her back with her legs spread, smoking. She slaps and plays with her pussy and tells me she wants me to eat it. Amy tells me what she likes and what she wants me to do to her pussy. I start to finger bang her and then we get into a 69 position and give each other oral pleasure. Time for some fuckin so I lay Amy on her back and start to put the meat to her. Amy's favorite position is doggie style and when I start to fuck her in that position, she pulls her ass cheeks apart and lets me ram it home. I finally jack myself off all over Amy's beautiful ass.
