Was it at the end of your time or shortly after the flip? Just wondering because about a year ago she told me there was oil as she was walking out the door but never mentioned it again. But other reviews seem to suggest they do it with her in the room. If you get a chance soon let us know
I had a session with Susan about 6 months ago which was exactly like yours- she told me about oil and tissues / towels as she was leaving the room. There was probably 5-10 minutes left on the clock. I haven't seen her since. During that session she was an incredible tease and I thought I might pop even without her touching me.
I did have Amy for one session since then, It was DIY and I haven't been back.
That said, if Susan turned the lights down for Dartspool, it sounds like she will stay in the room for DIY. There is no reason to turn the lights down if she leaves the room and you are the only one there.
Another review implied she was in the room, but the monger had to ask for DIY. And he said he had seen her a few times before this happened.
