Sure.

"Sure," I replied. I wasn't jealous of Bill fucking my wife since I was fucking his but I was curious what the two of them were doing in the basement.

Not bothering with modesty to cover ourselves, Emma and I walked downstairs with my softened cock flopping with each step. We didn't hear anything when we opened the door to the basement.

"Bill did a great job of sound proofing the room," I noted when we reached the entertainment room. Not wanting their families to know about their secret sex den, Bill used his skill and experience as a renovations contractor to make the wine rack into the hidden door to the hidden room.

Emma swung open the secret door to reveal the sounds of flesh slapping flesh that almost drowned out the loud grunts and moans. Stepping inside the secret sex den, with its blood red wallpaper and mirrors next to and above the king size four poster bed, I saw that Sam was strapped into the specialized seat of a swing Bill had added after our swinging days. He was standing between my wife's outspread thighs and was furiously pounding away at her pussy. Emma and I watched with fascination Bill, with a firm grip on Sam's slender waist, rock her back and forth along the length of his cock. Strangely enough, Emma and I were often too busy screwing each other to ever watch our spouses fuck. My once flaccid cock was hardening again.

"Oh God!" Sam repeated as she was continuously skewered by Bill's long, thick veiny rod. Good thing Bill had the room sounds proof because my wife is a screamer when she cums.

"Fuck!" Bill roared right before he ejaculated into my wife.

"That was hot," Emma purred, aroused at seeing her husband bang her best friend. It was only then did the two of them finally noticed Emma and me.

"Hey, guys," acknowledged Bill, shivering a bit before finally pulling out his softening cock from Sam's reddened snatch. Jizz oozed out from her slit and dripped to the puddle of cum beneath her. With her cervix sealed closed from her pregnancy it was not surprising Bill's load -- which despite his low sperm count he could still release a large wad of semen -- would leak out of her.

"Hi, honey," Samantha smiled at me with tired eyes.

"Do you want to rest a bit?" I asked her. It was clear that she enjoyed being fucked silly as much as possible before her small baby bump morphed into a large back pain inducing belly and sex would be that last thing on her mind after the birth of our baby.

"I'm okay," she replied, rubbing her sore pussy with one hand while caressing her stomach with the other. Good thing the baby was only about three inches long.

"Sweetie, relax while I get the boys hard again," Emma giggled as she knelt between Bill and me.
