So...here is what I remember.
When Nick entered the room, I was already naked and sucking David's dick.
David was on the couch, and I was on the floor in front of him.
I remember looking at Nick as he walked past me, handed David a beer, and then sat down next to him. I did not stop fellating David, or speak to Nick.
"That 12th hole kicked my ass today" David said, speaking to Nick.
"Yeah, they have done something different to that green, and it did not break the way it usually does" Nick replied.
Then David's cell phone rang. He glanced at it and announced that he had to take this call, pushing my head away from his penis, as he rose and walked across the room.
"Wanna blow me while he is on the phone?" Nick asked, now talking to me.
Without responding verbally, I wiped David's pre-cum and my own saliva from my mouth and chin with the back of my hand.
Nick stood up briefly and unbuttoned his shorts, letting them fall to the floor. He returned to his position on the couch, without ever removing the beer from his hand. I moved to my left and between his legs. I grasped his penis and stroked it slowly, licking the length of it as I did.
I remember Nick's penis got hard pretty quickly, and I slobbered on it as I forced more and more of it into my mouth.
For a while, I could hear David in the background, talking on his phone, and then I could not hear him anymore.
I alternated between stroking Nick's penis, and sliding my mouth farther and farther down it until I finally had it all down my throat.
I remember Nick wrapping his legs around me, and squeezing me tighter and tighter, and then he began to rhythmically thrust his penis, in unison with my sucking and stroking...and then he stopped.
Nick grabbed the top of my head and held it securely against his penis, as he began to cum in my mouth. I could feel his cum bounce off the roof of my mouth and then sluice down my throat. I swallowed more than once before the flow of semen finally subsided, and then carefully licked any remaining fluid from his penis.
"What the fuck?...I leave the room for a few minutes, and this is what you guys do?" David shouted from behind me. "What goes on when I am away for two days?"
And that is all I remember...I awoke to ESPN blaring some nonsense on the television, and both dogs lying next to me on the bed.
Honestly, I spend a lot of time imagining how an actual threesome with David and Nick might go down. I don't know how David would respond, and I am not sure how Nick would handle the whole experience.
I showered and went to work. I smiled each time I recalled this little dream the rest of the day.
When I got home, I sat down to write what you have just read. 
I should also mention that I went to a happy hour with Nick, the day of this dream. There was the usual innocent flirting and banter back and forth. I am beginning to realize that this flirting is something more than disingenuous.
David got home Friday evening. We went to dinner and had some normal sex afterwards.
Saturday night, Nick and some girl named Julie joined us for dinner, and we all went to a sports bar afterwards. I am sure Nick had the sex with Julie, and I would have loved to watch him dominate her…but that did not happen. When David and I got home, we had great sex. While I was on top of him, I whispered my dream into his ear as he fucked me. He spanked me and told me what a bad girl I was for dreaming what I did.
I am a big fan of dreams, but I am not sure what they mean...usually.
I think I do know what this one means.
