Either he's making an ultimatum to her that he has to appear in her photos now or he gets off on the idea of dudes jacking off to him? He should start his own OF at this point.
Yeah, you're over or under thinking shit. Dude's wife is dressin in sexy outfits, taking pictures and making bags for it. She's probably horny as fuck from the piles of money and the thought of all the hard guys that're givin it to her. I'm sure they fuck like rabbits after these and if they're smart and have even a thought of going hardcore they could be stockpiling content. He also probably helps keep her confidence up and what not. They're fucking married, this is what a healthy relationship looks like.
