They went upstairs.

I tucked my cock back into my pants and offered a hand to Sam to help her off the chair. She was a bit wobbly on her feet after getting pounded a couple of orgasms by Bill. I helped her up the stairs, leading Bill and Emma to our master bedroom. I'm sure Bill would have agreed with me that we would take each other's wives to separate bedrooms to bang but the girls insisted that we all be in the same room as the possible conception.

Sam and Emma laid next to each other -- luckily at four months pregnant Sam could still lie on her back -- and spread their long legs apart. Bill and I exchanged nods and knelt between each other's wife's thighs. All four of us were excited and nervous doing something that we had done dozens of times before we settled down and tried to become parents. The girls held each other's hands and smiled at each other before looking up at Bill and I to tell us, "We love you."

"I love you, sweetie," I said, looking across to my wife as I pushed my cock deep into her friend's tight cunt.

"Honey, I love you," Bill grunted over Sam's moan as his cock stretched her pussy.

Balls slapped ass cheeks as Bill and I sped up our thrusts. I hooked Emma's legs over my shoulders so I could lean forward to penetrate her cunt at a better angle. Bill on the other hand decided to hold Sam's thighs wide apart, probably to allow him visualizing his cock inside my wife's growing belly.

After several minutes of non-stop thrusting, the girls stiffened and cried out, begging us to fill them with our spunk. With Sam already pregnant and Emma desiring to be knocked up, there was no greater incentive for Bill and I to satisfy our wives' wishes. The two of us roared within seconds of each other and released torrents of semen into our wives' cunts.
