You say David1970 has exaggerated a bit ... I would say he's exaggerated a great deal...to the point of sounding very much like a big fibber. I have seen Busty Charlotte a few times 2 or 3 years ago ... around 2012/2013 in Slough. She was working under a different name then ... I think it was Busty Suzanne or something like that ... and she was nothing like he has described. She had silky black hair back then, was a size 14 , fantastic big tits, was chatty, friendly and spoke excellent English. Furthermore she was happy to give OWO. I visited her several times sometimes 30 mins, sometimes 1 hour, and I found her eager to please and no clockwatcher.
Just thought I'd give a bit of balance. But my experience with this WG is as far removed from the OP's experience as is possible to be.
I'm not sure I'd like to punt with her in her current premises ... if it is so dark... unless he has exaggerated that as well. In Slough she had a nice light airy flat and I could appreciate and worship her incredible rack in broad daylight.
