My fantasy

My wife admitted to me that - a few years after we married, she was having coffee with her college professor. She said she suddenly found herself desperately wanting to suck him off.
"Why?" I asked.
"I don't know. He just looked like he could really use a good blow job, honey. I'm sorry!"
"Why are you sorry?"
"Because I went back to his apt. and laid him on his bed, sat beside him and undid his pants. Took him out, and sucked him off. And, yes, I let him - actually, "made him" cum in my mouth He tried to be polite and pull out of my face - but I shook my head "no!"...and stayed there, fondled his big balls, until he came in my mouth. He sat up and looked at me - to see what I would do, with his cum in my mouth! I swallowed it, honey. I'm sorry - I just did!"
"He said 'thank you!'"
"I just smiled at him, let myself out as he lay there with a limp penis, and came home to you."
"And no - I do not remember if you and I made love that day. It was 2 yrs ago."

Just yesterday... the day before Valentine’s Day. After a couple of months of flirty texts. I walked into my bosses office towards the end of the day and I sucked him off. Well really he fucked my mouth more than I sucked him off. I’m married but I have always had the same urge as you. He used my mouth and filled my married mouth with cum.

Why is that bad? Most bosses would love that.
