My wife and I sharing the experience

The sensation of Gina riding my cock as I licked my wife's pussy, while I watched her in turn suck someone else's cock was intense.
What's the term? Pulling a train? It had been great screwing Gina on my own, and a lot of fun having a threesome with my wife and Gina, but this was something else. Somehow the addition of a fourth person seemed to make it even hotter, even though it was a guy. A guy that happened to be my boss, and have a really thick cock. That kind of made it weird, but not weird enough to counter the incredible eroticism of watching my wife stroking and sucking his dick.
"Fuck baby," I said as I paused licking her tasty slit, "you look incredible doing that."
She paused and looked back underneath herself, "oh really? What is it you like?"
"I dunno..." I began, "just seeing you let yourself go and really enjoy it I guess. It's so fucking sexy."
"Hah," Dan snorted in reply. "You think that's sexy? You should see it from my point of view. Not to mention feel it."
I have you idiot I thought, she's my wife remember
"Yea, she's not bad at that, huh?" I said instead.
"Not bad? She's more than just 'not bad'. She's so into my dick, she's fucking amazing."
"Yea, she is," I replied as my wife grinned from ear to ear.

I manoeuvred out from between her legs and sat up, then gently lifting Gina off, moved to the sofa beside Dan. It was kind of weird sitting beside him, both of us naked with our hard shafts at full attention, but the sight of the two naked women with us was enough to keep things focused.
"Come up here, Gina," I said, looking over to her and offering her my hand. "Come and suck me again as Melanie sucks Dan's cock. She didn't need anymore encouragement and came over and knelt between my legs beside my wife. Gina grasped my shaft with one hand, and gently licked from my balls to the tip of my cock. Her tongue swirled around and over the tip, and probed gently at my opening. Just as quickly as she'd started, she stopped, and sat back up. She turned to Melanie and pulled her in for a kiss. Their tongues dancing against each others as Dan and I watched. After a few hot seconds she pulled away, then placing her hand behind Melanie's head, pulled her gently down toward my cock.
"Lick it, suck him," she instructed and my wife willingly obliged.
"Can you taste me on him? Does your husband's cock taste like my pussy?"
"mmmmhmmmm," my wife moaned in reply, her mouth never leaving me.
"Do you like that, babe?" I asked.
"mmmhmmm," she replied again, still sucking me deeply into her mouth and licking my balls as she did so.
"You're so bad, baby"
She pulled her head off me, "hey, you started all this remember!"
I smiled at her. She was still worried about what I thought of her. "I know, I don't mean it like that. I love it."
"Oh, well in that case, I'm going to be even naughtier. I'm going to fuck Dan while you watch."
"Oh, are you?"
"Yes," she stated firmly. "I'm going ride his dick, while Gina rides yours. And he's going to cum inside me too."
Dan finally spoke up again, "That sounds great. But, what are you waiting for?"
"You guys to follow me," my wife replied, jumping up and racing to the door, where she paused and turned back towards us, "let's move this to the bedroom."
