They cuddled for a while.

Emma stiffened and shivered when her orgasm washed over her. She threw her head back and let out a scream of erotic bliss. When she finished climaxing she fell forward and kissed me. I was taken aback by the kiss.

I had read that prostitutes don't kiss their clients because they find it to intimate, even though they let strangers stick their dicks into their mouths and pussies. I can understand that thinking -- even though my wife and Emma have known each other since they were little girls and they had sex with their husbands, it was decided that the line drawn was kissing. The intimacy of kissing during the heat of carnal passion was too great of a risk for their marriages. But I guess the loophole was when I was having sex with Emma to try to get her pregnant -- the girls being eternal romantics wanted the baby to be conceived from love making.

I kissed her back.

We kissed like lost lovers reunited after years apart. Even though we had sex many times over the years we never had this kind of intimacy before. We finally broke our kiss when we heard Sam moaning, snapping us out of our own little world. Looking over we saw Bill continue to pound away at my wife, who was digging her nails into his muscular back. Emma and I watched with perverted fascination Bill bring Sam to another orgasm before he followed suit.

"Shall we go upstairs where it's more comfortable?" Emma giggled while Bill and her dismounted off of Sam and me.
