You arrive at house of the man that knocked you up on a one night stand months before. You tell him "look what you did to me," as you show him your growing belly. You tell him he is going to pay for what he did, or you are going to tell his wife. You are so horny and you haven't had sex since he knocked you up, so it's only fair that his first payment will be just that. You proceed to ride him hard to satisfy your sexual craving. As you leave you tell him you will be seeing him again you receive more "payments".
