There's also a surprising amount of bullshit in the listings.
I have had dozens of two girl experiences over the years, and I could count the amount of interaction between the girls on one hand, even though most claimed to be bi beforehand.
And of all these only one was what I would call truly no holds barred full on g/g action, although at least I enjoyed these ladies several times.
If you want a decent threesome with good Girl Girl interaction then the way to do it is arrange it yourself, pick two girls you have seen before but that do not know each other or work together, then arrive wioth one of the girls to see the other.
The reason this works is that BOTH girls know you and as such will not want to disappoint you, their loyalty (for what its worth) i to you as opposed to the other pro$$ie, I have done this a few times and if the girls are genuinely bi they really enjoy it and a good session follows.
Pro$$ies & pimps will make all sorts of excuses liek they like to work with their friend (They mean run through a pre arranged fake interaction) or they need to fancy the other girl, that is all bollocks as pro$$ies dont have to fancy clients to see them. Or of course they say it won't work as they are not bi and just fake it.
Genuinely bi girls will be up for it, and girls getting into each other for the first time is very horny.
