I've been to Boonma a couple of times as it is just a short walk away from where I live.
There is only the one Thai lady who is also happens to be the owner working there right now. Sorry I can't remember her name. And it is all the legit stuff she does. Nothing more.
I visited Boonma A week ago, took over by new owners 2 months ago.
25 half hour, I dont waste time these days getting down to asking about extras, so i asked straight out 15 mins in, and got a no, I dont understand, I do relaxing massage for you. Anyway after 30 mins, was up she suggested full hour to which i replied no thanks, and this indicated some swipes, 80 quid later, got a b2b fingers outisde, and happy ending and another 20 mins.
I initially did get the feeling these things werent on offer even though the massage was shit.
I dont like to share the girls names here any more in case it causes problems, so you can pm if you like.
