Sudden offer too good to refuse

I'm a high school dropout and exercise to keep a great body shape, which helps me get by. I attend hen's parties and strip and even fuck women who attend the party. That's how I survive financially. Anyway, I attended a party nothing out of the usual and as usual I leave a few businesses cards to encourage more work for myself. As a solo performer everything helps. A few days later I receive a call from a woman who had attended the party, and she wanted to meet me with a job offer privately. A motel room rented by her was the meeting place. The woman was 37 slender okay looking and successful and very confident person. At first, I thought she just wanted sex, and I was somewhat wrong. Sex was involved but it was just to get her pregnant. She just wanted a child not marriage and I was on her list of possible fathers of her child. Providing I passed all medical tests first, she paid for my tests at doctors of her choice, and I passed every test. No problems medical wise, a contract was produced, and I signed it. I liked the payment clause; sex was to get on deliver the sperm then get off. No foreplay just enter her leave my sperm get off. It took 5 deliveries before she got pregnant, all tests showed a healthy baby and I was paid, deal complete. A month after the birth of her son she contacted me again, no more sex just to enquire if I might be willing to make another child with her, same deal. I was very interested as the payment was excellent.
