It's Olympic Gold medalist on rings Arthur Nabarrete Zanetti nearly crushing his own skull with his obscenely developed muscles. He's a solopecocrushophiliac. Allegedly.
He's from Brazil, and his win marked Brazil's (and South America's) first Olympic gymnastics medal. I imagine that with his muscles, some tasks are quite difficult, like finding a suit that fits, and not constantly staring at himself in the mirror and masturbating. His grip strength alone could create awkward genital sensations.
I know it's 2013 and he won in 2012. Forgive me. I watched all the women's gymnastics first because I'm gay. And now I got around to watching the men's event finals [YouTube link] where I found this moment. Go team!
