My stepsister always takes advantage of people's good will. We recently went to dinner and she told me she forgot her wallet, so I paid, and today she comes to my house saying she's going to stay with me for a few months! Before things get out of hand, I decide to demand a way for her to pay me, and the only way we can think of is with sex, of course. She knows that I always wanted to fuck her and that I have been masturbating spying on my horny stepsister, and today my wish came true.... For 3 months I'm going to fuck her every day, all the time!
