It's on their site under 'rates and services'.
Basically $10 more for half hour session.
I think that the rates for all of their durations have technically increased, but they also had tiered rates before, and even the highest tiers of service (bodyslide, or fetish) put them as some of the lowest for a legit spa. I can’t see that being good for attracting new girls, or keeping talent.
I do think they shot themselves in the foot in some way, however. I am in favour of generally all-inclusive pricing. Though they apparently forbid girls to charge extra for fetish sessions, whereas most other spas have a $20-$40 surcharge (the only $20 one is Allure, which likely has to do with them having the highest rates, to begin with), so I can’t see that not narrowing the number of clients that will be fetish-friendly, at least with a first time client.
