Have her move in with you

As a breeder, you can tell right after ejaculation whether or not the girl got knocked up. Scientists still don't fully understand how, but rigorous testing has shown that a breeder's instincts are never wrong. You know right off the bat, Beth has your child inside her right now.

However, women who used to be infertile can have complications with the baby that would normally be impossible, as a baby born from a breeder is always perfectly healthy. The one way to ensure that doesn't happen is to keep dumping load after load into her body, and eventually your powerful semen will correct her body chemistry. It's possible that you could even cure her with your cum.

You sit down the couple and explain everything to them. They follow along well and understand everything.

"All that being said, I think the best scenario for you, beth, and the baby," and you, but no need to say that, "is for her to live with me for a few weeks so I can make sure she is healthy."

Jack and Beth talk quietly to each other for a moment before Jack comes up to you. "We both agree that it's for the best. Are you sure you don't mind having her over? You've already done so much for us."

Oh the burden of having a beautiful, curvaceous blonde at your beck and call. "Really, it's nothing. I don't mind at all."

Jack smiles at you. "You're too kind. Beth is packing her bags right now." He hands you his business card, "Please call if you have anything you want to talk about. And don't forget to bring her back for church on Sunday!" The both of you laugh.

You let the two of them say their goodbyes while you wait in the car. Before long, she comes out to the car with her husband, who you help put a few suitcases in the trunk of your car. They kiss goodbye for the final time and Beth jumps into the passenger seat. They wave to each other as you drive away.
