Ask her to stay with me, while Gina and Dan use the guest room

"Oh, well, I was kind of hoping to spend some time alone with you honey," I replied. "Why don't Dan and Gina use the spare room at least for a little while."
"Aww, that's so sweet, honey," my wife replied smiling, I want to spend some time alone with you too, but we've got plenty of time for that!"
She came over and kissed me, tugging Dan along as she did so having not let go of his now fully hard dick.
It was a little weird being able to taste Dan in her mouth, but not too bad all things told.
She stood back up and continued, "But, right now, I'm going to play with Dan some more while he's here, and you spend the night with Gina okay?"
"Okay, I guess"
"And I want to be able to hear Gina cum, so make sure you do me proud!"
She led Dan out of the room, leaving me alone with my sexy young colleague.
Oh well, I guess I should just enjoy myself

Gina was still lying on top of me, my semi-flacid shaft beginning to slide from her. She lifted up and looked into my eyes, "I'm so glad they're off in the guest room, I wanted to be alone with you. Just lying together like this; it's wonderful."
She didn't seem to mind that I'd wanted her to go with Dan, and leaned down again and kissed me. There was no lust this time, it was a slow intimate embrace as I wrapped my arms around her.
"I needed this, Alex. Sex is fun but I've missed intimacy. The way you hold me and look at me, I see affection there. Thanks." She leaned in and kissed me again.

Oh damn I thought, she's getting a little bit too much too fast
I had wanted to reconnect with my wife like this, but I couldn't deny that I was attracted to her too. More than just sexually, and I wasn't sure if that was a good thing.

We lay together, not doing anything other than just enjoying the feel of each others' nakedness against us. Gina's beautiful soft breasts were pressed against my chest, their warmth pleasurable against the cooling air as we lay exposed on the bed. We were both enjoying the moment together when Gina broke the silence.
"Can you hear that?"
"No, what is it?"
"Just listen for a minute," Gina replied as she slid off me to lie beside me. I lay still in silence, listening, then I realised what she'd heard. A subdued rythmic thumping.
"You hear it now, right? Gina asked. "Dan is giving it to your wife."
She was right, the headboard of the relatively cheap guest bed was obviously banging against the wall as my wife was busy getting her pussy pounded by my boss.
What a change I mused, thinking about how different my life was than only a few days ago.
As I continued listening, my wife's moaning now audible, a hand made its way down and started gently stroking me. I hadn't realised I'd got hard again as I'd been listening, but I was. Moments later, the hand was replaced by hot wetness as Gina began sucking my entire cock into her mouth.
