Super set of pics! Nipples and dicks can take huge amounts of pain, extremely sensual pain. At least mine can. Pins, needles, nails, clamps, pliers, vice grips. And thorns, like on a blackberry stalk.....Pure Heaven!!! These can even be inserted into the pee hole, but must remove them very carefully. I've never worn a crown of thorns but have had sex lying on a bed of thorns. Man on top, layer of thorns between, man on bottom, bed of thorns beneath. Indescribable sensation. Liked the pic of the stapled dick. Never tried that but will now. Thanks, Neon!
