There has been lots of talk in prior threads about "what is GFE". I personally don't expect BBBJ if a SP says she is a GFE. I think LFK, DFK, are the bare mininum. I also would expect that the SP's would respect the full appointment time so that in the case that the "main event" is finished, there would be continued caressing, massage, or otherwise contact until the appointment time had been fully utilized -- as opposed to the sp getting dressed right away and hustling the client out the door once the "shot on goal" was done.
It's a bonus when MSOG/extraball, or BBBJ is part of what the SP defines as the GFE experience for her. In some ways I think those two things cross into the PSE experience but for me are appreciated when are part of the GFE experience.
There are some SPs who offer a "gfe session" for "extra", and/or to also charge extra for BBBJ. For me personally, I would rather that sp's offer one straight up price for a session and what services she's comfortable with rather than booking a "reduced service" sesson where the sp spends a lot of her time trying to "upsell" you to other services (that is SUCH a mood killer). The one service that I don't expect to be included in prices and where I would expect an extra charge or at least require some pre-communication in advance, is for travels to Greece.
Again, just my 2 cents - take it for what it's worth.
