Well, the open mouth is kind of her trademark.
For me it often works (e.g. all three HOTEL covers look fine with it, especially CD only, where it feels kind of mysterious - her stare is just fascinating). But I wish for some more variety. Seriously, sometimes I roll eyes. Kuu, get out of your comfort zone!
But I can totaly see, where you`re coming from and that you don`t like it. We`re sadly just able to ignore it. I guess I`m used to it. Or often I don`t associate it like that, cause of the whole (mostly normal) setting of the pics, I assume. And overall I`m pretty open to sexual pics and images. As long as it`s somehow tasteful and combined with a strong woman. I totally don`t like sexual mixed with cute e.g. I always get a weird feeling with that...
Summer Trip covers were flat out porn.
