We don't usually have occasion to use the words "spanking fetish" and "environmentally friendly" in the same sentence, but then we've never seen anything quite like the nifty custom paddles at Burning Rubber before: a complete line of spanking toys made from recycled tire treads and street sign aluminum. As our friends at Boing Boing so economically put it, "Your ass may not be sustainable, but the product design is!"
