2 Bi ladies for sure.
Except for something that I heard about.
There was a provider that always wanted to taste another woman but never got up the nerve.
So...a gent and two bi ladies introduced her to the other side so to speak.
Did I mention one of the bi ladies was a Dom?
No one was in a hurry and what a day it must have been.
She never did say and I never asked but I think she is bi as well so I guess it really wasn't an exception after all. I vote for bi ladies.
