I recognise her. She has been around for a long time, is very experienced, and has always used the name Tammy. Maybe six or seven years, and started in Pimlico. She is Czech, but has been in London a long time and there are no language issues. I'm sure she's independent and pre-dates the influx of EE's. Agewise she was about 26/27 so I guess she would be 32/33 now.
She's a bit expensive for me, but I saw her a few times. Extremely good oral and swallow. I never experienced anything like it. Never met anyone else as good orally. She had me lie on my back with my legs apart, and crouched between my thighs. She gives a kiss and a cuddle but then goes straight to the cock. The foreplay is all in the oral. She will make it last a long time if you want, but I found it becomes so intense I can't take it for more than about 15 mins.
Good luck if you try her. Worth experiencing at least once.
