This is my favourite of your ALL your comments, Miss Squires.
It's so obvious to you ( and I for that matter ) that if a gentleman has requested S & S, he wants these to stay on throughout "proceedings" ! As you point out, quite tricky to "geremoff" if worn beneath the S & S, unless tie-sided !
The fact that you wear the panties UNDER the S & S in your AW Gallery is probably because you were trying to achieve the best "alluring photo" rather than being "ready for action", which is just fine by me, as I think this is a superb photo, anyway !!
