I loan my step-SISTER Money -- Guess What I Want as Payment

Description: She and her friend borrowed her friend's parent's car, and she wrecked it.  she really needs to get it fixed before they get home, and before our step-parents find out what happened.  she comes to me for help, since i still lives at home and have a good job.  i decide to help her out, but she thinks it was just out of love.  when i starts going to her for repayment, i make sure she realizes i have a lot to hang over my head.  first i ask to touch her, and then i want her to strip for me. eventually i tell her i want her to fuck.  she reluctantly agrees, and even though she demanded i wear a condom.  i just pretended to put it on, and then ends up giving her a creampie!
