Holy FUCK that dude looks a lot like me, though I have bigger arms and a better-looking beard. Jesus on a skateboard. It's like an ugly long-lost twin.
But yeah, he's getting cucked HARD. He obviously rolls the red carpet out for the slut and she makes the most of it while taking two dozen Chad cocks behind his back.
I find that any ugly dude with a hot GF is instantly taken down a peg when you ask "when was the last time she blew you or took it in the ass from you?" The answer is usually something like "for my birthday". Femoids love gobbling Chad cocks though, so unless the answer is "when we last fucked", cuckery and betabuxery is afoot.
