I saw Rosa once, a few years ago, at B&S.
Unlike the rave reviews that she typically gets on massageplanet.net, my session was not only fairly lacklustre, it was, well, just plain odd.
It was fairly late that night, and while she didn't say that she was tired, it became evident that she was exhausted. After I disappointed her by answering "uh, no, not really" to her "are you kinky question", she essentially fell asleep on top of me during our session...
As for her looks, I don't want to be impolite, but she must be looking rather old by now (although I expect that she still has a great bod).
