You guys may be right. He probably let her in on his revenue. They do have a pic of him taking a selfie while she's giving him a bj so she's at least aware of that.
It's a bit sus but I still think it's real, just two cringey individuals lol. As for the selfie, it's not unusual to take one during a BJ/doggy, and if they find out just play it off or delete. Travelvids does this all the time.
