Author's Note: This story is in part inspired by the hentai Mija Beautiful Demon. This is the prologue and from there, the series should have about five chapters.

Five figures stood in a circle on the roof above Francis Dee Academy. Above them, the first thunderstorm of spring raged. The wind howled. Lightning jumped from cloud to cloud. Cold, hard rain splattered every surface. It was a perfect night.
On the ground in the space between the figures was carved an intricate seal. The figures chanted together and as they did so, the seal began to glow like a hellish ember. Nearby, a bolt of lightning arced through the sky and struck a couple dozen feet away from the party.
One of the figures, a younger woman, yelped, drawing nasty looks from her fellow chanters. The baleful light of the seal wavered. She immediately fell back in line with the others and before long, the light of the seal was brighter than ever.
Soon, the chanting reached a fever pitch. The figures each reached into the pockets of their cloaks and pulled out an item. Every item was different. One figure held a family photo from Christmas. Another held an ornate hairbrush. Each figure eyed their respective item with a sense of longing and sadness. Then, after a moment's pause, they all threw their items into the glowing circle in front of them and chanted louder than ever.
The glowing circle erupted in light as a single bolt of lightning struck its center. The roof of the academy flashed with blinding light for several seconds.
When the light faded, a new figure could be seen crouching above the glowing circle on the ground. There were gasps from the group of five figures as they all took notice of the newcomer.
Particularly, the young woman from earlier yelped and fell backwards onto her butt. Her eyes were wide with terror and disbelief as she looked at the shadowy being in front of her. She tried to stand, but her feet slipped on the wet ground.
One of the other figures, this one an older man, spoke up.
"Mrs. Carraway, you are disrespecting the master!"
The young woman ignored him. Her gaze was fixed on the hunched figure in front of her.
"It's-it's real! I didn't think it would be real!"
"Being new is no excuse, Mrs. Carraway. You knew what you were getting into, no show some-"
The figure in the middle of the circle stood up, silencing the man immediately.
Mrs. Carraway saw as the figure stood that it was a woman - almost a woman. She had a feminine figure with generous breasts and a slender yet curvaceous body. Her skin was a light violet color and her hair a billow of black shadows. On her purple skin were many black markings or tattoos. From the sides of her head protruded two forward facing horns.
The young woman mostly focused on the being's face. It was a gorgeous face touched by supernatural beauty with full lips and high cheekbones. As Mrs. Carraway drank in the demon's beauty, she felt an odd stirring between her legs. A giddiness that made her temporarily forget her loving husband at home.
The older man spoke up.
"Master Zadza, I apologize for her impudence. She's new and -"
"Shut up, Anderson," the demon said. Then she turned her attention back to Mrs. Carraway. "What's your name, dear?"
Despite her overwhelming fear, Mrs. Carraway felt compelled to answer the demon.
"My name is Susan."
The demon seemed to taste this bit of information, weighing it in her mind before turning back to Mrs. Carraway and smiling. As she did so, she revealed long, razor sharp canines.
"A pretty name for a pretty woman."
The demon snapped her fingers and before Susan knew it, she was naked. Her robe and clothes were piled up underneath her. The cold rain stung at her exposed skin.
"A very pretty woman," the demon said.
"We can provide Mrs. Carraway as an offering, Master Zadza," the man, Anderson, said.
Without sparing a look to the man, the demon held up her index finger and fired off a bolt of lightning at the man. It struck him plain in the chest and sent him flying backwards.
Then the demon lowered herself on all fours above Susan Carraway and ran her clawed finger along the woman's midsection. Where the demon touched, Susan felt a pang of intense, tingling pleasure. She moaned softly.
"Mrs. Carraway," the demon said. "Does that mean there is a Mr. Carraway?"
Again, Susan felt compelled to answer the demon.
"Yes. My husband, Mark."
"How sweet. Does he pleasure you properly?"
The demon's claw came dangerously close to Susan's crotch.
"Yes! Of course!" Mary insisted.
The demon shook her head and frowned. Susan found she could not take her eyes off the demon's cherry lips. Although she knew it was wrong, she wondered what it would feel like to kiss those lips. What would the demon taste like?
"Your husband doesn't satisfy you," the demon said. "I can read it in every twitch of your beautiful body."
"What? No! Mark satisfies me just fine!"
"Oh?"
The demon shoved her clawed index finger between Susan's pussy lips, causing her to buck and squeak. Susan's pussy immediately grew hot and slick as it tingled with supernatural pleasure.
"Stop! Only he's supposed to touch there!" Susan cried.
