A hard cock is good for a lot, not least of which is acting as an improvised flagpole. If this package can hold a flannel shirt representing all hipsters and rednecks, we're sure we can sit on it, too.
Lest we forget, the human penis is technically an organ. Still, it's pretty hot to watch a guy lift things with his erect dick like he's flexing a big, veiny muscle. The fact that Xtube user jrwoods337744 is covered in otherwise big, veiny muscles certainly adds to the effect.
