To anyone reading this thread that doesn't know RevSand, he is one of the nicest and most professional people I have worked with in the adult biz. Sandy's honesty and integrity make it unlikely that he has embellished or made up anything which he wrote (indeed, he has the event on video as well).
I'm also not surprised that he didn't hit her back.
I probably wouldn't have hit her either - I was raised to not hit girls, and unless I felt I was in imminent danger of serious injury, I would likely do no more than block punches or restrain a girl.
I don't know Tanner, but it sounds as if she seriously needs some help...
