I have no idea where this is but I’m sure these guys were just using the mud for it’s mineral content and the benefits for their skin, right? Surely! Guys don’t just get nude and muddy for a laugh do they?
It’s a shame they left their shorts on for the mud application, would have been cool to see them completely covered in mud, but their white butts do look funny this way I guess.

Either way, nice butts! :-)
I’m guessing this was the Dead Sea in Israel. They have mud pits where you slather yourself with mineral-heavy mud that is supposed to be therapeutic. Just don’t have any cuts or it stings like a mo-fo.
