While I like watersports(one of the threads I follow here is the megathread for it), I hate "fake squirting". Women sometimes actually squirt, it is still piss but it is just one quick release, not a steady stream. It is an involuntary spasm of their urethral sphincter, usually caused by pressure from the inside towards the pubic mound and massaging the urethra. You pretty much never saw it in porn from the 90's or earlier, then suddenly one or two pornstars started doing it and now there is a glut of "faking it".
I also hate "faking it" by loudly exclaiming how good they are being fucked, when you can see in their eyes, it is just a normal, everyday fucking. Whereas, when it is real, it is spectacular. I know it is tougher when you do sex for a living. I have known a few "escorts", even dated one once and heard their stories, so I imagine it is much the same in porn, even if they get bigger dicks attached to dudes with better sexual stamina. Still, wish they would not "overact".
