I told Barbara to have a seat on the stool as I started snapping some pictures. I spent about 15 minutes taking various poses when I asked Barbara, " ...What did you have in mind with your comments earlier." "Are you interested in more erotic modeling?" Sure, why not," she replied. "Okay, then",I said, "pull those bikini bottoms aside. Let me see your pussy." Without hesitating Barbara took one finger and pulled the flimsy bikini bottoms aside exposing her cunt for me to see. I snapped a couple. ..I didn't know you had your brother with you....isn't he 14 now.....heshould be able to stay by himself at 14.....you're right, I know how yourparents are......He needs to learn to stay out of trouble.

The number, density, and quality of my sperm cells were not relevant measures of success. What mattered was the number of embryos emerging from a controlled sample of eggs and semen.

As my effectiveness was dropping, I felt uneasy and couldn't always provide the semen.
