Just a great looking thong rear. If your butt looks anything like this one why would you ever want to cover it. With all the extreme mens swimwear designs this standard thong cut mens swimwear design seems very tame.
I would venture to say that a thong like this would be at home at almost any beach or pool. Girls where these swimwear designs everywhere without a thought.
More and more guys are switching over to thong cut mens swimwear designs to get a great tan and show off excellent assets like this one.
