There are plenty of decent busty british blondes in london and the majority of them are just more than amazing.  
Allow me to introduce a few of them.  

One I do particularly like is Charis. As a Chinese who lives in the UK, in my opinion she has everything that required from an english woman. SOOOO Gorgeous and always willing to play.

Masseuse & Escorts

Hi hunny!  You’ll find quite a few masseuse’s are happy to offer escorting services ( usually at a higher rate )
 You will also find many escorts who offer massage services. Whoever you go with I would recommend you communicate with them upfront about what you’d like to experience and if they think you’ll be compatible in a polite respectful way. That’s the best way to ensure you have the best chance of experiencing what you’d like. Also have in mind some masseuse’s may take offence ( not all however ) if you ask about escorting services but if you search for an escort who is a trained masseuse or that offers massage, I doubt very much an escort would take an offence to such an enquiry before meeting.  
I was once contacted by a polite gentleman a few years ago asking if I could offer him a Nuru massage. I was honest and said I didn’t know how to do Nuru massage but was willing to research it and give it a go! he agreed and I had the pleasure of meeting him over the years giving him Nuru massages which was wonderful & for me to learn a sexy new skill  
Find someone passionate about what they do & keep communication clear and you can’t go wrong!

Thai Escorts give great massages and are a good price as well no extra charges
