That hasn't been my experience. My most recent encounter ended early. After a couple gags and released saliva she got up and said. "This is fucked up, dude. I can't do this. Just pay me for a blowjob and we'll call it even."
You gotta get better whores, who realize they are nothing besides worthless fuck meat, to be used and discarded.
