Focus, mate!
The process is fine.
The problem is to do with actual application; the models you listed-having "experimented" with hardcore, quickly went back to doing their standard "softcore" stuff!
The problem is they failed to actually make the Transition-basically, they were only using yet again another form of the teasing-technique! Not cool!
Had they stayed the course and continued their hardcore route with equal enthusiasm as they had with their softcore approach-it goes without saying that they would be just as (if not) more successful!
You can't say with a straight-face, that fans prefer being teased over seeing the real-thing!!! If you do-either you're a glutton for punishment or you're just a ball-face liar!!!
A nude Nikki is a dream come true-a hardcore Nikki is heavenly-it's as simple as that!
Tease-nude-lesbo-hardcore, that's the way you do it.....uh-huh, now!!!
