You smile as you stand naked by your Olympic-sized pool. It took some serious magic for you to upgrade your lair, but it will all be worth it. Filled to the brim with salt water, you prepare a series of spells. Your water-breathing spell is a must, but your mind-link spell as well. With your protective wards in place, you begin the summoning ritual and in a flash of light, the object of your desire appears.
Her massive, almost serpentine body glides effortlessly through the water. You marvel at the beauty before you. She must be at least sixty meters long! Her body is covered with a rubbery, black skin. Her head a spade-shaped carapace, with rows of red, lateral denticles running down her sides. Three sets of eyes stare at you curiously as you jump into the pool. Her segmented legs twitch around the luminescent, blue mouth which undulates on the underside of her massive frame.
"You look more like a meal than a mate," her voice rings a bemused tone in your mind. "Perhaps not even that."
The Shadow Leviathan nuzzles into you, pushing you around like a toy with her spade-shaped head.
"But I am intrigued," the voice continues. "I shall allow you to please me. Perhaps if I am satisfied, I shall see to your needs as well."
The Shadow Leviathan gives you a gentle slap with her tail. Although it's clear she was being playful, her size makes the strike sting. You smile internally, knowing this experience will be one like no other.
She reclines in a corner of the pool and you swim down to her. You run your hands along her massive, aquatic body, noting the thin membrane of mucous that seems to coat her skin. She makes a sound akin to a purr as you rub your hands down her lateral line, pressing your hands hard on her to get any sensation through her thick skin.
Her black, lidless eyes stare up at you as you begin to move from her tail back towards her head.
"This feels... good," her voice rings in your mind. "I've never had a mate who could touch me like that. I need more."
