This guy should have never let his girlfriend tie him up, but it's already too late to regret it. Now all he can do is stand there and moan of despair watching this slut get her brains fucked out by some horny douchebag she brought in to satisfy her. That's what you get for cheating on a vindictive slut who loves to fuck and knows a thing or two about revenge. Welcome to cuckold club, dude! Payback's a bitch just like your girlfriend.
