Alz'zethar was none too pleased with his new lot in unlife.

Not too long ago, the resplendent daemon had been a noble in one of the realms of Hell. A warrior, specially bred for battle against forces both hellish and divine, he had earned acclaim over several wars as a true agent of entropy known as a Tempest Hound. His body was tall, lean and muscular. His fur was the color of storm clouds and sparks of lightning would routinely zip across the contours of his flesh. His head was angular, almost jackal like, and his eyes swirled like the eponymous part of a hurricane. He was loyal to his mistress, the regent of his realm, and served her in several different ways.

"Alz! Alz! Come here, it's time to hunt!"

That all changed when some novice witch from the mortal realms bound him as her familiar. He was ripped from the comfort of his kingdom and thrust into servitude. His new mistress, perplexed as Alz'zethar, thought the spell was bringing an actual monstrous canine into her service. She had even built a shed for him in her garden as a hovel. Alz'zethar seethed at the tiny domicile he had tried to sleep in the first night.

Over the ensuing days the witch started to recognize her error and his true station, but relished in treating him like a pet. His new mistress was preparing for something, either a grand spell or an epic quest, and her need for a protector and companionship had brought her to summon the daemon who ended being Alz'zethar. It was clear that whatever was approaching had made her nervous, cautious, and lonely.

"Good boy. Look at that hare. We'll feast tonight!"

How embarrassing.

Alz'zethar served his mistress as was the bond in their contract, but he still sought his release. Although after dinner when the witch shed her robe to reveal her nude form underneath, welcoming him to her bed for the night, the demon hound noted that things could be much worse.

A witch summons a hell hound for companionship (and more) but ends up with a jackal headed warrior of hell in her servitude. But she isn't convinced he isn't an actual hound. Hilarity - and smut - ensues. Reddit PMs are preferred and if another prompt catches your eye please let me know.
