Hello, also new to this site. So, Baker Street Massage Parlours.
There are three near the station, two on Marylebone Road on the North side walking from Baker Street station. The first is Thai Spa which is a bit of a mystery and offers nothing, the second is Natural Ways which offers HJ (£20) and B2B (£40) with £40 for 45 minutes. Who you get and what they are like is pretty random, but the massages are generally good and firm and the HJ usually superb (Ruby, although not the most attractive creature to have walked this planet) is particularly good. Everyone is friendly.
The other the name of which I forget is actually on Baker Street near the Sherlock Holmes 'Museum', opposite the Lost Property Office. I went there recently for 30 mins. The woman I was allocated was friendly enough, not particularly pretty though. After ten minutes of amateur 'massage' she took my hand and put it on her knickers and moved it up and down. Same with the other hand. She then said "Do you want sex?" "What?" "Sex, I do everything, fifty pounds."
I didn't want to do it with her and made an excuse for 'no', I wanted a massage as my back was stiff (and my cock wasn't going to be with her). She went back to a hopeless massage, pestering me about having sex or Happy Ending with her until she finally stopped the shifting of oil on my back and walked out in a huff. Some service!
If you don't want to waste time (and money), go to the second shop on Marylebone Road, next to the sweet shop. You won't be disappointed.
