It's not innocent at all. She's a middle aged adult mother, he's a teenager, barely an adult. I never bought the counseling stuff. It sounded like yet another reason given by the M's who are full of explanations that may work in their world, but in the real world they come off as big time lie tellers.
I am sorry she lost her life. You have to wonder about the decisions she made as she opted to immerse herself into the unthinkable world of regularly paying lots of cash for "merchandise" to a teenager in a park.
