This guy is not a cuckold. He just loves sex experiments and money, so when some rich dude from an Internet site offers him some cash to fuck his pretty girlfriend he is quick to agree. He even stays home to hold her in his arms and watch her suck dick and get fucked from every angle. He knows his future wife always wanted him to watch her fuck another guy and now it finally happens. What a perverted way to make enough money for a new TV!
