I thought I'd tap the wealth of knowledge you perverts have on a situation I find myself in. I have a civilian f-buddy who dabbled with girls in her early twenties ( she's 40 now) prior to her getting married.  She knows about my hobby and is interested in me setting up a threesome with a provider so she can walk on the wild side once again.  

Any practical suggestions on how to make this the best experience for the civie?  She's a great girl and I'd love for her to have the time of her life.  I know I'll have to change condoms between girls but is it typical for the provider to DATY without protection?  I would think that if she provides BBBJ then BBDATY (is that an acronym) is on the menu as well. Any other tips? I'm still on the fence on if this is even a good idea so feel free to share your disaster stories as well.      

 Many thanks!
