Could someone tell me a fictional story about what is a pv?

Private Viewing is defined differently from provider to provider.  Typically it is an erotic session with dancing, lap dancing, adult toy play and you will be satisfied. Some private viewing providers are also skilled at domination and fetishes.  By no means it is a full service experience.  If you are looking for full service, do not go to a private viewing provider.

PV, in my experience, has meant that you get to the girl's room and pay her, and then she tells you that no service comes with that--the fee was just for a private viewing, and you must fork up more for some actual service.

Might have other meanings.
