I found a lead with this video being on MyVidster with the the title "An evening in the Mark and Marc household part 2".
In the comments for that vid someone posted this: The Top, Marc Christensen is Father Fiore in the YesFather gay porn series.
Searching for "Marc Christensen" I come up with nothing but I did find a couple YesFather episodes and the Father Fiore figure could be him. As Father Fiore may be a bit older, hair is slicked down, wears glasses and has a moustache making it hard for me to tell but hair is same solo and looks similar, nose and ear looks the same so could be.
Looking further, I found this account on MyVidster with several vids by these two:
Mark Marc
Appears they also had a MarkAndMarc twitter profile at one point now deleted. All there vids are rather short clips but maybe something longer will turn up. Didn't find anything on OF with the MarkAndMarc name.
This is progress anyway. Looks like they both were in vids made by SayUncle (which the YesFather vid were done by).
