I had email correspondence with two women who work together (ads on BP) and they both asked for detailed specifics about what I was looking for.  I decided there was a not insignificant chance of police entrapment and so broke it off, although I suppose they could have been worried about me being the police and thought getting what I wanted in writing would mean that I wasn't the police.  I don't think that would protect them though as I am sure the police would be happy to tell them exactly what they wanted before they busted them.

This could have been a very innocent error by two very new providers who have NO clue how to screen.  Or could be LE looking for you to set up an appointment.

Either or any way...RUN like hell.  I can't imagine any good would come from pursuing this!

Given:
1. Two women work together
2. On Back Page
3. And send you personal questions

I'd hypothesize that they have no reviews here on TER? Else, your question would be "I thought TER ladies didn't do things like that..."

The conclusion should give you the answer you seek. This (discussing sexual acts by phone or email) is very out of the ordinary, in my experience.
