Rachel Black was a five-year-old girl and the pride and joy of her godfather, Sirius Black. She was the spitting image of Bellatrix. "You must have got it from Dorea," he often said.
The truth, that Rachel's looks were due to her being the bastard child of James Potter and Bellatrix Lestrange, was never spoken. Rachel grew up believing Lily Potter to be her mother. Lily Potter, the woman who had sacrificed her life to protect Rachel from Voldemort. She had loved Rachel as her own. Rachel had easily figured out her true parentage, tho. It was quite obvious that she was Bellatrix's doppleganger. She loved her mother and wanted to be just like Bellatrix.
Bellatrix often visited Rachel, and had tutored the girl in dark magic from the age of three, to Sirius' constant ire. He hardly wanted his goddaughter to be a dark witch, but had little choice in the matter, as Bellatrix was Rachel's mother. Mother knows best, after all.
Despite himself, Sirius was proud of his goddaughter's skill in the dark arts. In just two years, Rachel had mastered hundreds of dark and black spells, over thirty dark and black rituals, and had forged her own magical sword. She had the skills of a master, but was a bit lacking in power and strength.
Today's lesson was different than usual. "You must now bond with your chosen dark power."
"Yes, mum," Rachel nodded. "Almighty protector of the moonlit sky, I beg of thee please heed my cry. Transform thy servant into fae of night, and bless me now with darkness nigh. I beseech thee, envelop me with thy flame, but first I shall call out thy name: Queen Fae of the Night!"
Black energy enveloped Rachel's prone form as she fell into unconsciousness. Her shirt was torn as black fairy wings grew on her back.
"Awaken, my love and take to the sky,
"Come to me now as the night draws nigh,
"Newborn Fae unfurl thy wings,
"To serve the Queen above all Kings."
Rachel woke and took to the sky. "I'm coming my Queen." Landing before the Queen's throne, she bowed. "My Queen."
"Call me mistress, my dear," said the Queen.
"Yes, mistress," said Rachel. The picture of complete submissiveness before her caused the Unseelie Queen to burn with desire for her newest servant.
"Come, my lovely, service thy mistress," ordered the Queen, spreading her legs, revealing her wet heat to her new toy. "Eat my pussy, slave." Rachel knelt down, shoving her face into her mistress' sex and pushing her tongue in. "Fuck yeah. Fuck me with your little tongue." Rachel continued to pleasure her mistress, earning moans of approval. "I'm cumming."
The Unseelie Queen came into her newest slave's mouth. "I want you to dominate your mother like I'm dominating you, understand?" Rachel nodded.
"Lay across my throne as I fuck you, slave," ordered the Queen. The Queen equipped a strap-on and plunged into her slave's young pussy. "Fucking tight. This is why I fuck my slaves when they're young, and keep my slaves young forever." As Rachel came, the Queen pulled out and prodded her slave's back door. "Relax." As her slave complied, she pushed into her slave's tight asshole. She dominated her slave, fucking the young girl's ass until the girl was a moaning wreck, and then pulling out. "Take the toy with you, and don't return until you've dominated your mother completely, before you go, clean the toy with your mouth. The Unseelie Queen moaned as Rachel sucked off the strap-on, using her magic to cum in her slave's mouth. That gave her an idea. "Before you leave, I'll impregnate you."
Rachel moaned as her mistress fucked her pussy again. She felt complete bliss as her mistress implanted her with her seed, impregnating her. "You will impregnate your mother soon. Now leave."
Rachel bowed before taking flight once more. "I'm coming for you, mother." The cool night air chilled her bones as she flew back to her mother, the toy under her arm. She swooped down from the air and tackled her mother to the ground. Sitting on her mother's face, she said, "pleasure me, bitch." Bellatrix complied, eating her daughter's pussy, savoring the taste. Her daughter soon came, drenching her face with her juices. Rachel then moved down, guiding her mother's hand to her dripping pussy. "Finger me, bitch."
Bellatrix grinned as she fingered her daughter's dripping snatch. "Does that feel good, my dear?"
"Yes, mum," moaned Rachel, "fuck me." Rachel panted, as her mother added fingers, stretching out her already used pussy. She went crazy when her mother began to fist her. "Damn it, mum, you're fucking me so good!" Rachel screamed her mother's name as she came. Putting on the strap-on, she pushed into her mother's pussy. As she fucked her mother, she squeezed Bella's breasts, causing her mother to moan. As her mother came, she said, "I'm going to knock you up with my little brother or sister." As she released into her mother's pussy, she pulled out, before pushing into her mother's tight asshole. She fucked her mother into a moaning wreck before pulling out and re-entering her mother's pussy. "Do you like being dominated by your little girl, mother?"
"Fuck, yeah." Bellatrix was on cloud nine. Her daughter, now a full-fledged black witch, and a Fae at that, was fucking the daylights out of her. Many a witch in the Black family had lost their virginities at a young age as their dark power claimed them. They were then tasked with dominating their close family members. Rachel would be sent after Sirius next, if Bella was right.
After completely dominating her mother, Rachel returned to her mistress for further orders.
