It is not uncommon for women entering the lifestyle to feel self conscious about their body. It's a recurrent thread here. Bottom line, she's got nothing to worry about. There's plenty of potential play partners who will find her very attractive.
I get the feeling that she's concerned about the lifestyle because she only wants to do oral sex. That's perfectly fine. Really. It's called soft-swapping, and there's plenty of couples that engage only in soft swapping.
And an accent? Even if she didn't speak English I don't see it as a problem, so long as she trusts you and you translated everything for her
The accent isn't a problem.
I'd say go to a club. You don't have to do anything. There's no requirement you do anything at all once you get in the door. Nobody's going to demand she take her clothes off, fool around with someone other than you, etc. Just like nobody forces you to take a drink if you walk into a bar, nobody's going to force her to play if she walks into a swinger's club. It's fun. Go. Relax. Enjoy.
I have to agree with fun4ds. Fooling around with a co-worker can be a recipe for disaster. The doctor's office? So long as there's a lock on the door and no internal windows
