Best Friend Fantasy

I want to make my best friend cum with my hands and my mouth. He and I are both married and we both have families. We have been friends since middle school and remained close for decades now. We live in different states so we only see each other a few times a year, at most. For years now I have been fantasizing about pleasuring him and it has become an obsession. I don't know how to tell him what I want to do to him. I don't want to ruin our friendship because a fantasy isn't worth what we have. But I can't stop thinking about it. I jerk off all the time thinking about him and his dick. Hearing him moan, making him cum. It drives me crazy. I don't want some affair and I'm not into other guys. I just have a desire to play with him once.

I've shown him pics and vids of my wife's body because him being turned on really turns me on. Once I showed him a video of me fucking my wife and while he watched, I rubbed my dick through my shorts. He watched me a little but focused mainly on the video. It was such a turn on doing that in front of him. I was hoping he would start rubbing himself as well but we were only a few mins from seeing our families again so nothing else happened.

I want him to watch porn and when he is really turned on, I want to stroke his cock for a while and then take him in my mouth until he explodes and I swallow every last drop of his cum.
