Fans who love Shione IN GENERAL tend to 'forgive' her the smut more likely.
I'm in that category. I see some of the stuff she's done for Puta Locura and, well, it's not my first choice of content style. That said, because it's Shione, I check it out anyway.
I see what you're saying about the concern that it might "burn her out". There's models that keep their act quite clean that stick around a long time, but equally I think there's models that get into serious filth and make a long career of that too.
Whatever the outcome and her choice of modelling, I hope we see a lot more of her.
