The Unseelie Queen was quite pleased with her new slave. A mistress of Black Magic, Rachel Black was the perfect avatar.
"My young slave, you have done well in subjugating your mother. You are now tasked with dominating and impregnating your Aunts and Cousin. The Baron already wants me to lend your services, but I don't share," said the Queen.
"As you command, Mistress," said Rachel, bowing and taking off into the night.
She landed before Malfoy Manor and knocked on the door. Narcissa Malfoy opened the door. "Rachel, what brings you here?" asked Narcissa.
"Aunt Cissy, you," said Rachel, drawing Narcissa in for a kiss, preparing to dominate her Aunt. "Your pleasure is now mine." Reaching down, she fingered her aunt to completion, leaning down to lap up her Aunt's sweet juices. Equipping the strap-on, she fucked her aunt to completion, releasing into her aunt's waiting womb. She then fucked her aunt's ass until she was a moaning wreck. "Did you enjoy being dominated by your loving niece?"
"Yes," replied Narcissa, hugging her Niece in the afterglow.
Rachel's next stop was the Tonks family home. She quickly found and dominated her cousin Nymphadora. The metamorphmagus was putty in her hands.
Dominating Andy was next. She fucked her aunt into a coma, leaving her sated aunt unconscious as she returned to her mistress.
The next six years flew by, as Rachel was trained by her mistress in both magic and pleasure. Her mistress fucked her regularly, and she gave birth to five children.
Then came Hogwarts, and thus her trip to Knockturne Alley with her mistress.
Her mistress first had her fitted for robes in Proper Wizarding Wear. She had her sword remastered at the Blacksmith's shop. At Fine Wands, she got her wand a tune-up. At Fine Staves, she got a staff. At the Apothecary, she got potion ingredients. At the supply shop, she purchased a golden cauldron, golden scales, crystal vials, a telescope, and potion knives. At the broom store, she purchased a Peregrine Falcon Racing Broom. At the Knockturne Menagerie, she purchased an actual Peregrine Falcon.
At Gringotts, Rachel and the Unseelie Queen met with the Black Family Account Manager, who also managed the Potter accounts. The goblin, known as Sharpdeath, was quite intimidating to the young Black.
"Miss Black, your parents left you with quite a fortune, and your godfather has given you even more. Your godfather has given you full access to the Black Family Vaults. Now to determine your heritage," said Sharpdeath, pricking the girl's finger, allowing the blood to drip down onto a yellow sheet of Parchment."

"The wand wavers won't know what hit them," grinned Sharpdeath. "You are eligible to claim ladyship for all of your houses. Here is the Black Ring, the Slytherin Ring, the Gryffindor Ring, the Ravenclaw Ring, the Peverell Ring, and the Potter Ring." Rachel took the Black ring, the Potter Ring, and the Slytherin Ring. "I am proud to present you with a goblin knife. Allow me to place your wand in your vault."
Rachel took the knife, handing her wand and sword over to the goblin. She would honor the Goblin Nation by casting spells with a goblin-crafted focus.
Her mistress was with her as she boarded the Hogwarts Express. "Don't worry, mortals cannot comprehend my presence."
She met a muggleborn named Hermione Granger, who was a lovely, brown-haired witch.
"Nice to meet you Hermione, my name is Rachel Black," said Rachel before leaning in to capture Hermione's lips. She kissed the bushy-haired bookworm passionately, and snaked her hand under the girl's skirt to rub her pussy.
Pushing Hermione back into the seat, she knelt between Hermione's legs and ate the witch out. Hermione moaned and Rachel's mistress watched with interest as her slave dominated her new friend.
"Rachel, you are quite good at this," Hermione moaned, "fuck me." Rachel equipped her strap-on and proceeded to fuck Hermione. The bushy-haired witch moaned in pleasure as her new friend dominated her. "So good!" Rachel released her seed into the Brunette witch, impregnating her.
The Hogwarts Sorting Ceremony went smoothly. Rachel and Hermione made it into Slytherin. That night, in the Slytherin dorm, Rachel dominated her dorm-mates, Hermione, Pansy, Daphne, and Millicent.
Classes began the next day. Transfiguration, followed by Charms, followed by Potions. In Transfiguration, they transfigured matches into needles. In charms, they levitated feathers. In Potions, they brewed the Cure for Boils.
That night, Daphne had Rachel's undivided attention as she went down on Rachel and took it up the ass until she was a moaning wreck.
The next day started with Herbology, followed by History of Magic, followed by Defense Against the Dark Arts.
That night, Pansy was Rachel's fucktoy, taking it in both holes like a champ.
The following day started with Potions, followed by Charms, followed by Astronomy.
That night, Hermione and Rachel made passionate love, frantically scissoring until they both came.
The following day started with Transfiguration, followed by Herbology, followed by Astronomy.
That night, Rachel's mistress showed the young witch who was in charge, dominating Rachel with the strap-on until the young witch passed out.
Thus was the pattern for the next few months leading up to the winter holidays. Rachel returned home for the holidays. Her mistress and her mother commandeered her time, she spent the entire break either being dominated or dominating.
The rest of the school year went by quickly, Rachel dominated every female in her year, and several years above. The summer holidays came quickly.
Over the summer holidays, Rachel did jobs for her mistress, from covert spy work to political assassination.
Rachel's years of schooling went by quickly. She was the witch in every other witch's pants, and she loved it. Her mistress demanded that her grades be stellar so they were. Every summer, her mistress sent her on missions.
