I believe the place you describe as a PV is more typically called a "jack shack."
In California these are usually set up as "Lingerie Modelling" in small shops, often attached to sex toy stores. You enter, meet a model or line up of models, review a price list of room type and times available, then make your selection.
The model will take you to a room that normally has a door (maybe with a "safety" window) and inside is a comfy couch for you. She then plays some music and does a fairly shitty strip show with different sets of lingerie until your time is up. She continuously hints that "tips will get you a better show," and that's when you notice the small table next to the couch. It has a box of tissues and maybe an industrial size bottle of lube with a pump spout as well. IF you tip, she invites you to "get comfortable" which is code for whip it out and start jerking. If you tip even more, she MAY offer to help you, either by coming closer or even giving you a HJ (really BIG tip needed) until you blow.
It very rare, at least in CA, to get more than a HJ. And most models will try to suck you dry - of cash - before they will do anything. IME, rooms rent for $40 for 15 mins to as much as $100 for an hour or more. The models range from 5 to 7, with an occasional 8-9 in looks. Tips are almost always required to get her naked and BIG tips are required to get extras. I've heard of guys who dropped $200-$400+ for a HJ, which is rather sad (no, not me). Generally if you match the room rent rate you can get her naked, but she will try to entice you to tip more and may never deliver.
I stopped trying these locally when I realized there are much better options available. But over the years I've seen these and tried them in Austin, Dallas, Nashville, Louisville, Phoenix, San Francisco, and a few other cities. Generally not recommended unless you have no other viable options.
