Now this story wasn't (at least for the first 3 chapters) entirely my idea, it was from a guy from fimfiction who had this idea, but he hasn't been on the site for a long time and I wanted the story to continue but it wasn't happening and so I decided to step in, since I'm taking a hiatus from my other story for a little while.

For the first 3 chapters some credit goes to him,

Enjoy…

Rarity was reading one of her romance novels, lying in her almost queen sized bed. The story in general was about a beautiful dark queen, who just wanted to be loved, but had no experience in proper socializing, because of the dark history of her kingdom.

As the high school girl was absorbed in her book, she didn't noticed the black smoke entering her room through the open window. It didn't had any kind of form, yet it's "head" seemed to be looking around, before quickly hiding under the bed. Rarity looked up from her book, thinking to have heard something. Her gaze fell upon the window and she concluded it just had been the wind.
Shrugging to herself she returned to her book, while the black cloud looked up from under the bed.

About thirty minutes later Rarity closed her book and laid it aside. Before shutting off the light on her nightstand, Rarity put on her sleep mask and laid back, snuggling into her blankets and entering a blissful slumber.
In the meantime under her bed, the black cloud waited for another hour or so until it made its move.

Flying upwards it watched the sleeping human for a few seconds. Then the cloud lowered and then wrapped itself around Rarity's and lifted her up off the bed.

Careful not to wake her up, it then tilted Rarity's head a little, then it absorbed itself into her head, so it could enter her mind. Once completely inside, Rarity's body unceremoniously hit the mattress.

Inside her dream, Rarity was wearing a beautiful blue dress complete with blue diamonds adorning it just at the right places. She was watching herself in the mirror, posing like a supermodel would do, when suddenly a woman walked up from behind. Startled a little, Rarity turned in order to greet the woman, but somehow couldn't bring herself to speak a word. Instead she stared at the woman, who quite easily was the most beautiful woman she had ever seen, even rivaling supermodels like Fleur De Lis. She wore a blue dress, which revealed quite a bit of her naked body, black stockings with high heels and black gloves. Around her neck was a black collar with a blue diamond in the middle. She wore blue lipstick, her hair was violet with white streaks in it and when one looked carefully, you could see that the eyes of the woman were draconian like and glowing in a faint blue.

"You're quite beautiful." The woman spoke, putting a hand on Rarity's cheek. "But something is missing." she continued moving her hand under the chin of the girl and forcing her to look into the eyes of the woman. "A certain touch..." the woman brought her face closer to Rarity, their lips only inches away from each other. Rarity didn't care. She was too enthralled in the beautiful eyes of the woman. "A certain touch of...darkness." The woman then gave Rarity a gentle kiss on the lips.
Rarity wasn't sure if this was reality or a dream, but she didn't really care. As soon as her lips and the lips of the woman had met, she had felt something inside her. And she liked the feeling. The woman gently kissed Rarity's lips again. And again. And each time the feeling would become stronger. A dark, exciting feeling.
The high school student dared to move closer to the woman, who seized the opportunity to wrap her arms around the girl and this time passionately kissed the girl on the lips. At first Rarity was taken aback, but after a moment she started to kiss back just as passionately, her lips fighting with those of the woman.
Rarity let out a moan, when she felt something inside her pussy! In fact the woman had put two of her fingers inside the pussy of the girl, who was now standing naked in front of the just as naked older woman. Hadn't they both been wearing clothes only a few minutes ago? Rarity didn't care. She didn't know why, but she felt so alive, so sexy and goddamn it, she was horny. She moved her arms around the woman and forcefully grabbed both ass cheeks with her hands. Unfazed the woman continued with her two finger assault, while at the same time starting to kiss down Rarity's neck.
The girl moaned in pleasure and cried out loud, when the woman added two more fingers. It didn't take long for Rarity to reach her climax with those skillful fingers of her sex partner. Throwing back her head, she let out a scream, as the juices floated out of her pussy. The girl leaned against the woman's breast, who was stroking Rarity's head and chuckling darkly. The woman snapped with her fingers and suddenly she and Rarity were lying on a bed, with Rarity being at the bottom of the woman. The woman then opened her legs, inviting Rarity to lick her pussy.

The high school girl didn't need anything else as a command. She quickly crawled over and started licking. The woman in return squished her own breast, while at the same time pressing the school girl's head between her legs.
"Oh yes, that's a good girl. Hmm, I wonder...oooh...are you a natural or do you perhaps...yesssss, that's it...do you perhaps have experience in this kind of activity? Ahh...I beg to the latter." The woman moaned.

Rarity blushed, not that her partner could see her. The juices she was licking up tasted like the divine nectar of the gods. Unbeknownst to her, the woman was mumbling an enchantment, which caused Rarity's entire body color to slowly turn from white to a deep black. Not only that, but she also grew in size a little, her hair was getting longer and changing color and her breast were now as big as the ones of the woman receiving pleasure. As said woman began to reach her climax, she got up and pressed Rarity's face against her pussy.
"Now drink Rarity. Drink and be reborn as the one and only Queen of the Night. Accept the darkness! Accept MEEEEEEEEEEE!" The woman screamed as the juices flooded into Rarity's mouth, who devoured it all, while pleasuring herself with two of her own fingers. She moaned uncontrollably as she felt herself all of the sudden becoming stronger, her soul being corrupted by the very essence of the Nightmare. She couldn't get enough, she needed more darkness, more pleasure, more power. Both Nightmare and Rarity let out a final scream, before it turned into one and Nightmare Rarity woke up…
