From the looks of it, I think it may be filmed in Hungary, Czech Republic, Serbia, or Russia. I looked around and found similar videos featuring the two perpetrators. It seems they pay these people before doing anything with them, so this guy probably did give consent beforehand. Don't take my word for it though.
I am still trying to find the source of these videos if anyone knows anything.
P.S. As to the young man in the video, I think he's kinda cute. The guy receiving the BJ is somewhat hot, but he's a creep.
