I really like the little straight massage places that are peppered around Bangkok.
The ones where the ladies wear the cute uniforms and the massage takes place in a tiny booth or behind a curtain.
You never know for sure what you're going to get.
Sometimes you get a great professional massage, sometimes the girl just rubs oil on your skin.
Most often you are offered a hand job, but sometimes more.
Sometimes you get offered nothing by way of a happy ending but I'm fine with that, there's usually a blowjob bar nearby to take care of things in those rare cases.
I still remember one lady in a very formal looking straight massage place beside the Asia Hotel. She would have been in her 30s, very cute, great body, nice natural milk. The massage was great and I was thinking there was no happy ending coming then she asked and I said yes. Once she got underway she wanted to "upgrade" the happy ending to a visit to my hotel - unfortunately I wasn't travelling alone so it wasn't an option and she seemed very disappointed. Maybe I had "potential sponsor" written all over me. She was tiny, about 140cm or 4'7" to my 199cm, if I'd stood on my toes she wouldn't have needed to bend down to suck my dick. I love short curvy women with big milk so that's one I'll always regret missing out on.
Had the switcheroo a couple of times as well, cute girl beckons you in and takes you to a room and tells you to undress and lay face down, next thing you're getting fondled by a katoey (not that there's anything wrong with that if you like that kind of thing). Once they start nudging the tackle I suddenly remember I'm meeting someone for lunch. :)
