Gettin Boned @ MMU! (Patreon)

The MMU Naked Spelunking Club visits a mysterious cavern hidden in the mountains of the lonely Serpent's Isle, far out in the Southern Ocean of Maria IV, only to discover that one of the most fearsome beasts of ancient key'vin'ta mythology is actually real! Not one of the interlopers escapes being boned, their souls becoming eternally trapped in new vertebra which form in the tails of the spine-serpents who boned them.
