Mine (no pay/tricking involved either):

Been with 2 once...could've been 3, but one didn't really get along with the other, so she only brought her friend along.

I couldve been with 2 on another occasion, but one kinda had a b*tchy attitude, so I just stuck with the one.

And the BTG I had a TS 3some with also almost hooked me up with a TS/Genetic Girl 3some! We was at a club, and they wanted to go get a room with me...but I had to work the next day. Too bad, b/c I never got that chance again.

So that's my next goal...to had a 3some with a TS and a real girl!
