A friend of my girlfriend is a hairdresser and works from home. I went to get a haircut with him, and we were alone.
While I was getting my hair cut, I felt his cock touching in my arm and it was hard.
We were talking while he was cutting my hair about experiences and curiosities, and he asked if I had ever had an experience with another man before meeting my girlfriend and I replied that no, I hadn't, but I wouldn't rule out the idea if I were single. Then he said, “Too bad you're not single,” and laughed.
Since then I can't stop thinking about the hard cock touching my arm and about sucking it.
