I've mostly only been to Foxx Parties events, and sadly pussy licking seems pretty rare there. I don't think I've ever seen any of the other attendees partake, which is something of a mystery to me, as it's a pretty much essential part of the sex act to my mind.
It varies from girl to girl, a few were happy to do so, but that just makes it all the more awkward having to keep asking, and it all seems very odd to me given how rare it is to find a girl who won't receive oral in one to one meets.
Anyway, I'm just one data point, for all I know things are quite different at other parties.
