I've actually used A LOT of BP Female providers, so I speak from about roughly 30 encounters. It's really hit and miss. I notice that most of them actually look like their photos. There is a whole group of Thai/Pinay women who know each other, but work for different companies, who advertise. They often share hotel rooms. So, when you actually show up to the place, they wait to give you their room number and you can often see the other girl in the photo, walking out into the lobby if it's a "1-on-1" session and you've not selected both providers. One of my favorite encounters has been from one of these providers and so has one of the worst.
Also from my experience, they usually rotate around meaning that they come back, after about a month or so. I've noticed that most of the one's I've used, have narrowed down to use Shinjuku Granbell Hotel or one of the APA branches. There is also a lot of "fake moaning" sometimes even without penetration. Some providers get really moody, if you squeeze their tits because they're often fake enhancements. A lot also double book for the same time with clients so if you're lucky you're the first one, otherwise not.
Almost all, have not been time watchers with me. They've let me stay about 10~15 minutes overtime. I would rate their services on average a 6/10 from the thirty or so I have seen. They are also more likely to form LT relationships with you if you see them often enough. I meet two of my providers for lunch or dinner, when they are in Tokyo (at no cost).
A tip: I've often negotiated their prices WAY down from their original advertised. Usually 10,000 yen less. It's comparable to going to a Chinese bargain market.
Hope this helps! All the best.
