Scorpio
Scorpio is one of the Zodiacs, the scorpion boy who belongs to the dwellers of the deep caves and other abyssic creatures. His element is Water and his most flexible body part is the genitalia, which is lessay quite stretchy XD
Like many abyssic creatures, he has an obscure fetish for compressing into small spaces, squeezing through tight tunnels and other claustromaniac tendencies. He very much love contortion and stretching of any kind as it allows to pack even tighter or and conquer even more sophisticated passages.
