check out Sugarbabes International..

It seems that many Euro porn stars have made videos in the US or with US companies. Isn't it possible that the main PS escort agencies (TLC, etc.) will at least know or have contact info for some Euro babes in Europe? It shouldn't hurt to ask. With enough notice, they might be able to make some contacts and arrange for someone to be in Paris to meet you, even if she has to travel from a few countries away. (For some reason, I'm thinking of the amazing Eastern Euro girls, like Gina Gerson / Doris Ivy. It seems that a lot of Euro porn comes from Budapest. Are you Hungary for someone from Budapest?)
.
If things work out, as you leave your Euro babe, you'll be able to say to her, "We'll always have Paris."

And for the Bogart flashback.  Yes, apparently there are a ton of PS based in Budapest but traveling, even in Europe, seems a bit much and I'm only available for 2-3 hour meetings at most . The sites I've found feature reasonable rates for quality performers, for instance Sharon Lee and Aletta O but not as many in Paris as I'd imagined.  I'll check Sugarbabes now.

Following up...reached out several times and several ways to two of the only recognizable porn stars in Paris during my brief visit -- Katia de Lys and Monica Santhiago -- and did not hear back from either.  Ended up going with two TER reviewed non PSs and had a great time with one and a decent time with another.   I believe that language is definitely a contributing factor, as my Google translated texts and emails clearly didn't get the job done.
