Catherine TOG
I have seen Catherine TOG more than once and I believe she would allow MSOG because she is very accomodating. But Catherine isn't very friendly. Amazing skills, amazing ass, amazing menu, just isn't overly friendly. But, with Catherine, she will never fuck around with your time and play games like many SPs do. Catherine is very professional. She won't talk behind your back, won't play games on the board, won't get involved in drama. She is a great SP overall.
Ziri
Ziri, I don't recommend. She told me she did BBFS with a client once, so I always stayed away from her. She told me it was a 1 time slip-up and she hasn't done it ever again, but I don't want to engage with any SP that does BBFS with any client - even if it was just once.
Cici Palmer
I suspect Cici wouldn't allow 3 - 5 shots in 1 hour. She asks for $300 per hour and usually the higher end girls don't allow that sort of thing. Just my suspicion though as I have never seen her, so I can't comment on whether she would or not.
In general, as you mentioned, most girls don't allow more than 2 shots in an hour and most guys can't produce more than 2 shots in an hour. On a good day, i might be able to get 3 shots in an hour out, but I wouldn't want to. I am more of a 1sog guy with pillow talk for the remainder. Problem is that most girls play the 'I am a dumb blonde' routine when you try to have a conversation with them. Massage parlour girls are more likely to have a convo with a client. One of the reasons I like MPAs better than escorts.
