I did it!
Pretty straightforward. Met up at a hotel, he took his pants off, I got down on my knees and went after it.
He was an older gentleman, I'd say 65ish average height an build, healthy side of average cock.
Tried to remember things I like, paying attention to the balls, tongue flicks etc. He pushed it down my throat and made me gag, which he seemed to like and hit my face with it and when he was ready I knelt below him and he came on my face. The heat of it was kind of neat, he took some pics and I left.
