Not sure whether this fits here, but I would appreciate it if someone could help me identify this guy (i.e his instagram or twitter handle).

Any idea who these guys are or what the name of the movie is? I'm pretty sure they're Japanese.

Does anyone know who the bottom in this video is? https://xhamster.com/videos/strong-daddy-5-9719958#mlrelated
There are a lot of videos of him getting fucked by different daddies out there, so I'm pretty sure he has an xtube channel or something like that. I saw somewhere that his name is Eric but I don't know much more than that.
Thanks in advance.

No idea what that last one is, but the first two are from BEAR1978_ on xtube. https://www.xtube.com/profile/bear1978_-17570311#videos
