Just was wondering what “secret g” means with this girl? https://www.theeroticreview.com/reviews/sky-2133209456-355440

Sky aka Jasmin aka Silk is a provider who has advertised Greek in the past.

Thank you. I was just about to delete this since a found another site that stated Greek and figured it was that. Good to have confirmation that my assumption was correct tho.

Any idea why it's advertised as "secret G" instead of "Greek"?

I can’t speak for the thought process of the copy writer. But anal is frequently talked about as another way of stimulating a woman’s g spot.

Any word if shes staying in LA or coming back to the BA?

Its another way of saying YMMV and that there are more guys who DON'T get Greek with  her then do.  Hence, its a "secret" shared by a few.  In other words, she will do it if she's not intimidated by how much sausage you're packing, but she has to see you first, so there is no way to book it in advance and be guaranteed to get it.  

I’m a standard size issue white boy in the pants and I’ve had a couple sessions with MistressX where anal was enjoyed but a couple where she wasn’t into it. If you go in jack hammering them most will pass.
