When right before allowing her to have the big "O", I tell her the envelope is empty and I'll catch her next time...The BUCKING of that kind of cowgirl is tremendous!!
Rules will make me stop a session and roll out with the quickness. I think we all understand that there are certain no-no's in this business. But I've gone to see providers that just have a terrible case of the no's. No I don't do this, no I don't do that, it costs extra for that, you can't touch me here, no DATY without a dental dam, NO,NO, NO.
If I wanted to hear all of that shit I could stay home and fuck my wife for free. I'm not going out and spending money to have something provided to me that I can't get. No thanks, I'll go see someone who doesn't have as many rules.
