A chilldo is a dildo filled with silicate gel which can reach subzero temperatures. If placed in a deep freezer, ultimate pleasure can be achieved.
Damn, Dawg, that chilldo froze her pussy up real good. I thought my dick was gonna fall off from frostbite.
I wish Richard Gere hadn't shoved that chilldo up my ass. I've been shitting ice cubes for a month.
