My wife and I will be visiting San Fransico next week and are interested in having another women join us for a couple of hours of fun. Any recomendation would be appreciated!

Natalee at http://san-francisco-escorts.cityvibe.com/escorts/list/120940.htm is excellent.  Also, try Natasha at http://www.natashanz.com/ as she is highly regarded, extremely beautiful, very expensive and truly bisexual.  Lastly, for a completely different experience, you might contact Sadie Red at  http://tasteofburlesque.com/.
