I have only seen the trailers on that site but they have the guy handing her the donation, which is a no no.
I don't like how they show the woman getting dressed and made up in the bathroom before the sex. It makes it look too much like a job. Would rather see her come out of there then watch the clothes come off. I've been with a couple porn stars and the sex depicted is realistic from my experience.

TNG does a pretty good job in accurately portraying a typical outcall expeience with upper tier Providers. The exceptions are

[1] Handing the cash to the lady who quickly makes her way to the bathroom so she can count it. In real life the fee is always in an envelope and the lady discreetly slips it  into their purse or bag.
[2] Usually there is no excusing herself to the bathroom to change into a sexy outfit. But that does happen on occasion. Especially if the gent has made a special request. Not too many ladies are gonna walk through a hotel lobby wearing a school girl or sexy nurse outfit...lol
[3] Of course BBFS is fictional

I like the site. Quality production and outstanding selection of stars. However it is kinda pricey considering only one new scene is introduced per week. Plus they could mix up the formula now and then. Like maybe have the gent meet the lady in the hotel bar  or  forget the changing to a different outfit and do the traditional transition from sipping a glass of "get to know ya"  wine to making out.

Maybe I ought to become a porn critic...lol

I used to be a big fan of this series but got bored with it and cancelled my membership long ago. It's expensive considering you don't get access to other content besides just TNG like other porn sites. Loved the concept though with the hotel room, phony exchange of money, lady calling her handler to say everything is kosher. It's obvious the producers were trying to appeal to hobbyists like us but didn't do all their homework.

It also seems like the quality of talent has gone down hill over the years, but that's not just TNG it's porn overall. I see very little new talent emerging that I find sexy or interesting to watch. Honestly all the pornstars that I would consider paying 1k+ an hour to see have all long since retired. Sad but true. There are a few exceptions, but not many. Just my 2 cents.

I'd say it's pretty accurate including bareback. Most porn stars at least those that I have seen will allow bareback with a current test. Maybe one aspect that's different is if the pornstar is touring then you go to her hotel.

Not too accurate, really

First, the guys are crazy hot.  Providers wish!  Second, the first few minutes are a bit more awkward, the chit-chat a bit more nervous, and the conversation throughout is more real.  Often a main topic is the industry itself.  But I like the series.  Girls will sometimes want to excuse themselves to change.  I always tell them no, all I want is them in their birthday suit.  if you let a girl in the bathroom like that you are going to burn up at least ten minutes off your clock and that is an expensive waste of time given their rates.  I find the actual conversation with real girls much more interesting and fun.
