Has anyone any good ideas for ways in which bondage can be done discretely whilst in public?

Master once bound my legs together (above my knees) under my skirt and took me out for dinner. I could walk but negotiating the stairs was another matter entirely We certainly attracted some strange looks lol.

I have always fancied the idea of having my nipples tied and accessible for Master to pull, use thread perhaps?

Master has just bought me a leather harness to wear under clothes when we're out, hopefully we can find some way of attaching some "buzzy" friends to the crotch strap

Any other ideas would be gratefully appreciated.....
