I've had a look around for a good massage with happy ending and I'm not sure you'll find what you're after.
There's a forum all about it called fbsm
but after registering with them and reading a few posts it seems to be a niche market.
Mostly with clothed massage and HR.
Apart from that the girls on AW who offer nude massage are £100 +, then you may as well just go and get laid!
best to have a good massage in a normal professional place and then go for HR elsewhere. IMHO
