stars seem to be changing

It used to be someone would enter the industry and do vanilla porn for a while, and eventually they may go anal, then maybe go all out, then you wouldn't ever hear from them again. Seems to be the opposite now days. Sure there are still some who work this way, but there are a ton of women I've seen who start at LegalPorno and other hardcore sites and go all out hard and fast, rough as fuck, then give it all up and stick to vanilla afterwards. And the stars who return, fuck, some of them are hotter than the last time you see them.
