When my slaves get naughty I like to dress them in leather and attach weights to their nipples and clit. Nothing makes me happier than placing my slaves hot tits in my metal breast bondage device. I also really love to wrap my naughty slaves in leather and watch them try in vain to squirm. Leather is the pre-eminent BDSM material. It works for garments. It works for collars. It works for leather belts to whip someone with, and for proper leather whips as well. It works for straps. I have even seen leather corsets. I mean, what would BDSM be without leather?!
