y'know, for me it makes the visual even hotter when they are so concerned and nervous about *possibly* showing even a glimpse of something....the look on the face, the constantly attempts to hold the skirt down... this visual is
incredible.
(*I think that on a psychological level, it's probably because this adds to the "forbidden fruit" aspect of the visual....it sells the pic even more as something hot that we're *
not supposed to see* at that moment.)
