Listens to his wife.

Talia whispered, "Do it." My orgasm hit me so hard it hurt a little. Load after load shot out into Amy's waiting body. Her panting slowed, and we held each other for a moment.

I rolled off, and sat up to get a look at my cum dripping out of Amy's beautiful pussy. Talia smiled, and we kissed, and settled in to watch Rachel fuck Corrine. It was a study in contrast, the petite, short-haired Rachel pounding away at the statuesque, blonde bombshell. Before too long, Corrine reached her second climax of the night.

Then we all piled into the bed as best we could.

Elizabeth mused out loud, "Guys, I think I'm bi."

Everyone laughed. Rachel snorted, "No shit!"

"I'm not, but I do appreciate head well done." Corrine added.

"I'm so grateful to my wonderful husband for understanding that I want a woman sometimes."

"Just one woman?" Rachel looked across to Talia.

"OK, many women."

I paused a minute to reflect on how fortunate I've been to know these extraordinary women, how glad I was that we were all still so intimate. "Best birthday ever."

Stephanie answered, "You're a lucky guy, Ian."

A thought occurred. "Amy," I asked, "did you offer a blowjob just to get the condom off?"

"What, can't a girl get a creampie every now and again? I'm on the pill."

There was a moment of silence.

"Actually, I have a confession." We all stayed still. "Ian, I'm... I'm pretty sure that you're Adam's father."

We all froze. "How...?"

"Do you remember when I came to see you right before finals? I think... I might have missed a pill or two around that time. I was hardly sleeping." Emotion crept into her voice. "Don't hate me. I'm sorry I didn't tell you sooner. There was another guy right after that, but I found out recently that he's... sterile or something. I'm rambling."

I moved to hug Amy, and Talia joined me. Three naked bodies pressed together.

"We don't hate you," Talia said. Ian told me all about it years ago. Hell, I got off on thinking about it."

"What really?"

"I seem to recall logging off of AIM and having a good time with my dildo."

Amy kissed me passionately, then kissed Talia. Next I felt Elizabeth's lips, and saw Talia with Stephanie. Then I found Rachel, and Talia found Corrine. Finally, I met my wife in the middle.

"I want a large family with Ian, and I already consider you girls family. I think that wouldn't be so bad, having a blended family with all of you. I really hope..."

She trailed off, and we all fell asleep.
