GFE Sheffield used to advertise Mckenzie as being mid-thirties and you can clearly tell she is a bit older. Still looks great though and an excellent shag, very different to Sophie funnily enough, more PSE to Sophie's GFE.
I agree, particularly about the GFE/PSE. I definitely prefer Sophie in the looks department, I'd say McKenzie is just "good".
This may sound dumb but I've never really known the difference between fk and dfk, I mean it's all tongues isn't it? I'm happy with whatever variation they want to give.
Yeah that's a very good point you raise and you are essentially right. The way I see it is:
Kissing: Just lip-kissing with perhaps the odd, infrequent flick of the tongue at most.
French Kissing (FK): Tongue kissing, sensual, pleasant but not deep/passionate. No "tonsil tickling" here.
Deep French Kissing (DFK): Deeper tongues, passionate/more "tongue wrestling" (can sometimes be almost aggressive on her part), could involve some "tonsil tickling".
There is a level above that too, which is too much for my tastes but pretty much all escorts will tone it down when they see you're not reciprocating.
It's probably ridiculous that I've gone into such detail but I think it's fairly important for such distinctions to be made, especially for some people even though others won't care.
