does the idea of being naked with your hands bound behind hour back while someone pulls you along by a dog leash through a crowded public place turn you on? if it were legal (aka, you wouldn't get in trouble) would you do it ever?
If there wouldn't be any negative repercussions, then definitely sign me up!
did these questions inspire you to get naked outdoors? if so please share your experience (what happened, how you felt etc)
When I have time again it definitely will
