Compensând datoria cu un futai

I crashed my old man's car and now I'm in trouble, so I asked my stepsister to help me out. She gave me somethink to fix it, but now that I still don't have any there's just one way I can compensate 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 quit hitting on me until I put her on her fours and fuck that tight slurping pussy to orgasm! Debt in full, fuck yeah!
