Paying the debt with a fuck

I crashed my dad`s car and now I`m in trouble, so I asked my stepsister to help me out. She gave me some cash to fix it, but now that I still don`t have any there`s just one way I can pay her back. Man, it`s so obvious this bitch wants my big cock and she ain`t leaving my room until I fuck her good. Damn! She just won`t abandon hitting on me until I put her on her fours and fuck that tight slurping pussy to orgasm! Debt paid in full, fuck yeah!
