Striptease is an art. the girls in my opinion do a fine job of seducing the eye and heart, without having some nuance lacking checklist to obey. There are sufficient barefoot scenes already, to satisfy the most ardent foot fetishist.

Personally I find bare-ass butt nakedness boring. I like seeing breasts and ass and other parts as revealed in glimpses or while the model is in heels or stockings. Tripple X content is sufficiently arousing regardless of the degree of undress the model exerts. I think they get it right presently.
