True swallowing videos where the cock stays in mouth while cumming

A classic. Does anyone know the actual original story behind this one?
I genuinely have no idea but I know I've seen it a handful of times over the years but kept losing my bookmark to it. Finally found it again! There's a longer one with the guy setting up the camera and everything here:

Blonde twink is sucking his co-workers dick in the office

I couldn't download that one though, so had to hunt down one I could to share it with everyone.
 
Wonder if the sucker has any other content anywhere. It kind of feels like he recorded it just in case the guy he was blowing tried to do anything shady — based on the "do you promise to take this to your grave" comment he made and the wedding ring, he was definitely cheating. Maybe the boss?
