I think this is one of Nathan's best videos. Usually, once he brings his dick out he'll start jerking it and forget about flexing. In this one, his dick is out the entire video and he doesn't even touch it, he just keeps flexing. And what a fine body he has to flex. He's really RIPPED here, in his best shape, and those ABs - God, I want to bury my face there and lick all of those ridges.
