Billy lay side-on to his aunt. He swivelled his face to smirk at her, his long cock leaking pre-cum so the head was all shiny and the shaft slick and ...reasy in his fist.“Why should I stop?” Billy said to his aunt. “I like it.”“You’re disgusting,” she said.Billy shrugged. “Everybody does it. I didn’t invent it.”He was right, of course. But there were limits.“I’m your aunt, Billy. I don’t want to see it.”“No?” he said, raising an eyebrow. “So why do you leave the door open when you’re getting. Since you indicated that you were a breast man, and I am well-endowed, I will assist you with your donations. I assume that you like making out a lot."John had only read about making out. It seemed the impossible dream. Monica the nurse helped John produce his first sample to be tested. All she had to do was show a little cleavage and he got off. The sample was poured over hamster eggs and it fertilized them. He was in.He was to come in Monday, Wednesday and Friday at 7:00 am. Later he would. I could hear her squelch. I knew she was turned on.I was mesmerised. There was my quiet wife getting fingered whilst I watched. God, I was turned on and hard. John stopped and I thought that would be it but Ann turned to Sam and smiled and said to her,“Are you up for it?”Sam smiled and reached out for Ann. They looked at each other and they started to kiss slowly at first, their breasts just touching, nipple on nipple and they were into it. Their hands were all over each other. I watched as Ann. When her expanded womb would no longer permit vaginal penetration, she insisted that I do her up the rear, while fingering her in front. A couple of times, she came so hard, I thought she'd expel the baby just from the strength of her orgasm.When I raised the issue, she just grinned and said her OB had told her to do whatever was comfortable. Her body would tell her what she couldn't do.OK. I could live with that... I was still getting the best sex I could imagine.Near the end of April, Hanna.
