Sons friend

I was pretty anti gay for the first 40 years of my life.
I got married. We had a son and daughter.
When my son was about 12 or 13 he started bringing a little boy home from down the street. They became close friends. Over the next few years I kept telling my wife he was gay and didnt want him around my son. But my wife didnt believe it.
Then before they graduated my son said he admitted that he was gay. They remained friends. The next few years he turned more flamboyant and the whole world new.
My son moved to another state for school. They didnt see much of each other.
Fast forward 10 years. I was divorced. I had started reading craigslist. Got curious about getting my dick sucked from a guy. Tried it and slowly got into it plus more.
I started getting my cock sucked and topping a guy a of the internet but semi local. One day he asked if I would be interested in a 3 sum with his friend. Both bottoms and they liked to have 3somes. Heck yea. Who wouldnt like that.
So the night in question. I went to his house. He said his friend was running late. We got naked and started. He was laying on the bed and I was fucking his mouth when his friend walked in the bedroom. Yea you know where it's going. It was my son's old friend.
We both stammered for words.
Then he said it was a child hood dream. He said he had a childhood crush on me in high school.
They both sucked my cock and I fucked the guy we knew. He started calling me and sucking my cock pretty regularly the last year.
