This is so bizarre and over the top that I think the far more likely scenario is something consensual. Maybe he was a dick to her afterwards and this is revenge or maybe she's just crazy also. All kinds of crazy things happen in this world, but I think the possibility of this being some crazy chick is much higher.
Yeah, this story doesn't jive. Maybe there was subtle jokes and she saw an opportunity to set him up for a law suit. Blow the guy, save some his jizz and make an easy buck.
It's hard to believe a guy would just turn around, jack off and then turn back to face her for the money shot. I mean, if you're going to make a move there so many better ways to do it.
Either way, even if it's consensual, you can't be having sex with your patients during an office visit or treatment. The guys an idiot and just ruined his life.
I swear, I wish we could just turn our cocks off or on depending when it's needed.
