Sensual Jane may have had a decent figure, but yeesh her face (and arguably hair) did her no favors whatsoever. Put another way, I submit that sufficiently beautiful models don't need to (and also argue they shouldn't want to) shoot porn.
Think about it. There may often be severe social consequences for it (beyond nude model, I think? In some American cases, family members want nothing to do with them), and "pornstar" has a very non-negligible chance of, shall we say, extremely-curtailed life expectancy, whether through drug overdose, or self-deletion.
In any case, I maintain that so far, Mysti has come across as "all show, no go". When Luna is practically naked in front of her and that does practically nothing for her? Yeah, something's not right there.
