Bred By The Minotaur - Creatures of the Night

Lily was barren with no medical treatment available that could heal her. Witchcraft is her final option and she sets out to summon a demon that can give her what she wants. The ability to become pregnant. But the demon has a price to heal her. She will have to let the demon breed her and then have her give birth to their offspring. The small demon she had summoned didn't seem like someone that would cause her any trouble breeding offspring. Little did she know that the demon had a bigger form, a much bigger form that would be the one taking her, stretching her body to its limits with an appendage that matched the size of the real demon.
And from big demons comes big offspring. Offspring with only one way to leave her. Will Lily find the price for her fertility too high or will the witch embrace her fate as a breeder of demons?
