Obsessed Since Having A Dream.

I considered myself a happily married man...very straight. But then I had a dream a few years back.
In the dream I walked down a long hallway and as I neared a door I could hear a woman having an orgasm. The door was slightly ajar so I pushed it open and walked in.
At the far side of the room as a bed and on the bed a guy with a big thick cock and a woman riding him. Her back was to the door all I knew about her was she had a nice ass and long blonde hair.
I approached the bed and came up close behind her and got down low so I could get a close up view of this guys cock stretching the blonde's pussy.
I got my own cock out and started to wank myself. At this point the woman glanced over her shoulder and saw me wanking while looking at her gorgeous pussy wrapped around the guys thick cock. I was shocked and excited to see that the woman was my wife. She didn't seem surprised to see me.
I looked past her to see who the guy was and it was a friend of ours and an ex work colleague of mine.
My wife started to grind hard against his upward thrusts and was soon orgasming again.
She moaned so long and loud and then told me to lick her clit while she rode our friends cock.
Naturally I licked her, but at the same time couldn't help licking his shaft as he pushed in and out of her. The dream was so real. I could taste her juices on his cock.
This got me very hard.
Our friend (obviously the Alpha male in this dream) then told her to lift up off him, which she did. He then told me that since I'd licked his shaft I made it obvious that I wanted to suck him.
I started to deny that, but then thought why not?
I put my mouth over the end of his cock just in time for him to ejaculate into my mouth. This shocked me awake and I was very surprised to find that I myself was cumming right then in bed next to my sleeping wife. I gripped my cock and dashed to the bathroom trying not to shoot cum all over the place as I went.
Since then I have been obsessed by my friend and wanting to suck his cock.
More to be revealed about this in later confessions.
