i recently revisited Naga's Den and found an entire section i had missed; a collection of images based upon the wonderfull idea of a magical latex brush that allows anyone to painted with it be altered temporarily.
"This mysterious magical item is the center piece to a weekly bondage party held in a secret location. No ones sure where it came from nor even what all its powers are. It looks like a normal brush with a rubbery handle whose bristles are constantly wet with liquid rubber. This Brush never runs out of magical latex which can be brushed on to any part of a person. The latex can change the body upon which it is painted, making it into solid inanimate but living rubber, or making it into pure air leaving the victim a living inflated doll, as well as leaving it as normal flesh underneath, or any mix there of. Any body part painted with the brush can be reshaped, or painted completely away. A person could brush their legs into those of a satyr, or add a rubber tail, or could have a part removed completely with only a patch of rubber to show where it had once been."
