Some guy off the streets getting a massage w/release and she loses control and wild porn sex ensues?? In your wet dreams, you've been watching wayy too much porn.
Actually I've had it happen to me a few times that I was going the CBJ route, and the girl got lazy and said "fuck me instead". They usually tried to upsell it, but I didn't go for it so they just did it for the CBJ rate.
Every time but once the girls claimed it was because they were tired or sore jaw or whatever. One time the girl said "Here, I'll give you a present" and climbed on.
Thinking about it, though, I don't think it ever happened in BC. Only in Montreal I think.
I have always wondered about the fact that SPs and girlfriends are opposite on the BJ vs FS issue.
With an SP, the BJ is cheaper and FS is more.
With a girlfriend, it is MUCH easier to get FS than a BJ, because the BJ is more work for her (and probably less fun too).
So, why do SPs charge less for something that is more work for them? Never made sense to me.
