Time flies when you're having fun.

Even though I had continued to meet up with Emma during our lunch breaks at the motel and later in the evening gathered with our spouses -- taking turns hosting -- there was nothing boring about the repetitiveness of always having sex twice a day every single day for a week. I could not think of a single negative thing of having to fuck a gorgeous, voluptuous former lingerie model. Well, it wasn't a negative thing but it would have topped off the week if I could fuck both Emma and Sam at the same time.

I was very anxious at work on Friday, realising it would probably be the last time I would ever fuck Emma again. With her pregnant, all four of us would be typical responsible parents living in the suburbs, albeit with a shared secret sexual history. I love my tall, beautiful redhead wife with all my heart and I sensed other men's envy and lust of her, so I would never cheat on her lest I wanted a divorce. But the past week brought up memories of carefree sex with Emma, memories that were the embodiment of a "Dear Penthouse" letter fantasy come to reality -- I got to fuck my wife's best friend with her permission and encouragement. Part of me secretly hoped that Emma wouldn't get pregnant by the time she ovulated so we could continue swapping spouses under the guise of knocking Emma up. But I wanted to make my wife happy which meant making Emma happy and the only way to do that was to get her pregnant.

Right on schedule about half an hour before lunch I got a text message from Emma.

Emma: r u rdy 4 lunch?

Me: Sure

Emma: cu! :)

I told my co-workers the same excuse I had used all week, that I was going out to lunch with my wife. They've met my wife before so they perfectly understood and didn't suspect I was actually fucking my wife's best friend.

I drove up to the motel room that Emma had booked for the week and spotted her SUV parked out front already. Out of habit I knocked.

"Come in!" Emma answered.

"Holy shit..." I mumbled when I opened the door.
