you pay for sex.  When was the last time you picked up a girl in a club or bar?  I agree that these are about as stale as they come.  You DO need some new material.

If I had a hammer

I'm telling you guys, I  am pretty sure I would have made one hell of a cocksmith!  I'm entirely convinced of it..  

And if given the chance in another life.. when I would decide to break some biddies off real proper like (paid or not)  
I would undoubtedly say things like..
"You like when daddy's deep inside you?"
"Do you get this wet for all your dates?!"  
"You feel so hot inside" "Look it's dripping it needs it"
"You're pussy is milking me it's so creamy and tight"
"Clench that pussy tight for me..that's right. Now tighter, make this hard dick cum!"
"I'm going to bring you right to the edge and pull back just so you can beg for my cock." "You like begging for this hard prick?!?"
"Make yourself cum for me like you do when you're all alone"  
 
Or how about..  " Don't feel guilty giirrl, everybody deserves some level of job satisfaction." Hope this helps

Heck it was your idea.

Whether it's me saying it or her.

The lines almost don't matter ..... it is all in the delivery.  If you are confident and your delivery is great, it is over.  But if you look like you don't know what you are doing or sound awkward, you probably look like a schmuck.  

You're not sticking that thing in me ... lol
