I got all dressed up and yet again my boyfriend ditched me. You hate the way he treats your step-sister but I love his big cock so I accept any treatment he gives me. But I'm still horny and needing cock up my ass tonight. You say this can't happen again but I say it can. I tease you with my asshole and pussy until I convince you to pull out your cock and go down on you just enough to get you rock solid. You then fuck my asshole until you bust a massive nut and I play with all that delicious asshole flavored cum and clean up your cock. You know you'll never get tired of fucking your own step-sister.
