i am completely bare and have been for about a month or so. usually we like to have a little triangle or something but lately i've been given a rule to stay completely bare. i personally don't care either way, i just do what my owners want me to do... and lately this is what they want!
as to relation to spanking or D/s... i guess it can contribute to vulnerability-- i think that's why my owners want it on me (plus they like the view). but as for whether more spanko girls do it than regular girls... i'm not so sure about that. wouldn't you say, Rg, that you do more of this kind of information sharing with spanko girls than any other?
i think here may be your explanation. although i do appreciate your effort to give us a more R-rated topic.
