Eggs are, by far, my favorite substance to use, specially in BDSM contexts and humiliation scenes. Besides fun, egg someone can turn on a very humiliating scene, of course that should happen between consenting adults. But I must confess that I prefer to use the shells, for me, they're part of the mess and it's amazing when all those shells get entangled on a girls long hair, and, when an egg is cracked not on, but over the head, and the eggs slip down directly to the floor, it's just a wasted egg. I would love to see and buy more scenes with eggs and shells used in large quantities.
