You know you're dating the wrong step-sister, don't you? I see the way you look at my tits and ass - which are WAY better than hers! Unlike most of the losers my step-sister dates, you're actually kind of cool. Too bad you don't have the guts to be with a bad bitch like me. Not that I'd actually want to date my step-sister's sloppy seconds, but I'll fuck you just to show you how much better I am than her. I bet that prude doesn't even suck your dick right. I'll suck you good and then titfuck you - something my flat-chested step-sister can't do! After that I'll ride you in cowgirl and reverse cowgirl so you can see my DDD tits and thick, juicy booty bounce while I talk smack about my step-sister/your girlfriend. I like to be on top so I can be in control and I'm not getting off until I'm done with you - not even if she walks in and catches us!
