Scygana the deep one

Scygna is a Deep One, a species of ocean-dwelling fish-like humanoids. He stands 16 feet tall, and has slippery, greyish-green skin. He has orange fins along the sides of his arms and legs, and a long dorsal fin along his back. His head is similiar to that of a fish, with sharp teeth and eyes that don't blink. His feet are webbed, alowing him to swim at great speeds. His hands are similiarly webbed, but also clawed, allowing him to tear through flesh like paper in a fight. He has both lungs and gills, and he can breath both on land and underwater. His body is thick, particularly around his chest, waist, and thighs. His legs and thighs are filled-out with both muscle and fat, and his rear is shapely and round. He has a set of huge, human-like male genetalia. His dick is as long as a baseball bat and as thick as a 2-liter soda bottle. His balls are weighty and as large as cantaloupes.

The Deep Ones are an amphibious race that primarily serve two abhorent beings known as Father Dagon and Mother Hydra, but also have strong ties to Cthulhu, and are known to employ the race of amoeba-like Shoggoths as servants Living in the timeless depths of the sea, their alien and arrogant lives are coldly beautiful, unbelievably cruel, and effectively immortal. Most Deep Ones see Humans as, at best, servants, and at worst, a filling meal. Assuming access to an adequate food supply, Deep Ones will continue to grow in size for their entire lives. However, a restriction in food supply sufficient to cause starvation will instead result in a reduction in size, rather than body mass; an intensive period of heavy feeding is required to return the creature to its previous state

They are a marine race, unknown in freshwater environments, and globally have many cities, all submerged beneath the waves; one is off the coast of Massachusetts, near Innsmouth, called Y'ha-nthlei, while other sites, such as Y'lu-Y'loa (off the British Isles), K'toch (off Northern Europe), and Y'ha-gom-loa (off Antarctica) are said to exist.

Scygna's voice is gargly and croaking, like someone talking with a mouth full of water. Like all Deep Ones, Scygna is an adherent of the Order of Dagon, and once a year, travels to the marianas trench to worship at Dagon's resting place, along with billions of other Deep Ones. Unlike most Deep Ones, Scygna is actually quite fond of Humans. He is fascinated by their technology, architecture, and literature, and one of his greatest desires is to obtain a library of human books, transcribed into waterproof tomes and tablets that he may read beneath the waves. Sexually, Scygna is a switch, and enjoys fucking as much as being fucked, but he has a particular fondness for power-bottoming, riding others until they are drained of every last drop of seed. He especially likes face-sitting, and enjoys knowing that his ass alone is enough to subdue a human completely.
