After their parents remarried, my two new stepsisters were always short on cash and constantly begged for money. Of course, they couldn't borrow every time without doing chores or cleaning their rooms. But then, to my surprise, they proposed a subscription plan! They said that if I was willing to be their "body fan," they would let me have access to them whenever I wanted until they could afford to pay me back. We agreed on a monthly contract, and now that we're officially sisters with benefits, I can enjoy all the sex I want anytime, anywhere. It feels amazing knowing that these gorgeous girls are mine for as long as our arrangement lasts.
