The hellhound looked like a shadow wreathed in fur. Powerful muscles rippled as it shifted its weight. It crouched on all fours, looking up at its master, amber eyes glowing with a baleful light. The scent of a female in heat drew the hellhound's attention, and it turned its wolfish head to gaze across the room. Master had to tug on its chains to keep the hellhound in place.
A young woman, barely out of her teenage years, was being forced down on the thick wooden table that occupied the middle of the room. Master's helpers - the tyrants, he called them - were holding her in the correct position; bent over the table with her feet on the ground and her face pressed against the rough wood. The hellhound stood in excitement, straining against the chains, and whimpered with desire. Standing upright he was much taller and larger than his master, but he knew better than to struggle free; disobedience would be harshly punished.
"Calm, Shadow." Master crooned, stroking the hellhound's jet black fur. Hellhounds were what happened when a werewolf was resurrected by a necromancer. They were violent, dangerous beasts with no memory of their human life and no mercy upon their victims. Only through continual satisfaction of their sexual desires could they be rendered somewhat tame, and taught to follow orders.
Shadow shifted his weight from foot to foot impatiently. His erection strained against the chains wrapped around his thick black cock. This was a method of control; Master had the key that unlocked the chains, Master controlled whether or not Shadow could use his favourite toy, and so Master had to be obeyed or the desire would build and build until Shadow was a writhing mess of desire and longing, locked in a tiny cell, aching to rut against something but unable to move. That had been his fate once when he had accidentally torn apart a prisoner of war Master hadn't wanted harmed; he would be careful not to disobey again.
"I am going to free you, now." Master breathed in Shadow's ear, and the hellhound's tail wagged excitedly. "You must not kill this one. Understand?"
Shadow was too distracted by the scent of the girl, and he whined, tongue lolling out of his mouth. Master slid his hand in between the wolf's powerful legs and squeezed Shadow's balls, making the hellhound yelp.
"Understand?!"
"Yes!" Shadow panted. "Yes, Master, please...!"
