Could you post here some pornstars and/or pics of pornstars who has their asshole visible without cheeks coming into way or without spreading with hands. I think it is about shape of butt mostly but lets try can we find any!
What are you asking? Lady is just standing there, not bent over and not spreading her butt cheeks, and you can see her asshole? I don't know any like that. Can she be bending over? Post us an example of what you're looking for (with proper attribution).
Very good. Any more those where the woman is just standing? (Some have so tight cheeks that asshole is visible even not bending or spreading, rare species but possible)
Not to be too pedantic, but for us fans of this, having just one thread would probably be better. If nothing else, it will avoid duplicate threads, which the Mods frown on. There is a more established thread that fits what this one is looking for:
