Gymnasium Genetics

I saw these shots on a message board, and had to save them.  Although this bodybuilding father and son are not nude, they're incredibly hot!  I think the shots of them flexing in their skimpy baby blue posing thongs actually elevate both their muscles, and their hotness!  I also love their identical adorable smiles.

I had a bit of difficulty however, finding out who they are.  The shots are on several sites, but none that had credits that I could find.  One person replied that they looked like fitness champions David and Dylan Tepera Check, but I don't think that's who they are.  If anyone has any idea, please let me know.
