I don't get to "play" much so I'm very hesitant to post here; I'm wondering if anyone else happens to share this particular kink (one of my favorites). Leading a girl around by a leash on all fours or upright with hands bound behind them, or holding a tight lead during sex or is a huge turn on; I guess I'm just wierd that way.
It's a sensation of power and humiliation, I suppose, but most people don't seem to enjoy this activity (even many who are into bdsm) and I would never ask someone to do something they weren't comfortable with. It can hurt, too; when pulling on a lead, it should be done from the front to avoid hurting one's partner.
Since most people here are far more active or knowledgable than I am, I wonder what you think--should a good sub be allowed to go around unleashed?
