Good Auntie (R18+)

Bellatrix had been having a strange week. Her last memory before her traitorous husband froze her in stasis was of him going hunting for someone important. He said the war would soon be over, but he never returned. He took everything from her. Her daughter, her time, and her life. All gone.

Now, a decade and a half later, Bellatrix finally saw some hope on the horizon. Her niece, Nymphadora, was powerful and she driven. They only spent a few hours per day together, but Bellatrix knew she was something special.

In the Black family, to show emotion was considered weakness. The tender care Nymphadora had heaped upon the former servant of the Dark Lord quickly wore down her walls. The two were soon as close as true family members, much like Bellatrix and her sisters before the blood war.

Bellatrix asked about her sisters from time to time, but Nymphadora never answered. She shut down all such conversations with a flawless smile and promises of answers in the future. Bellatrix was a little suspicious, but wouldn't dare to question her niece, her benefactor.

Bellatrix still wasn't sure how exactly they'd ended up in bed together. It had been an ordinary evening. They'd trained their bodies and magic, followed by a scrumptious dinner prepared by Dobby. One glass of wine turned into an entire bottle. Before Bellatrix could protest, they were naked and embracing in her childhood bedroom.

Bellatrix had messed around with her sisters when they were younger, but never anything too serious. Some kisses, maybe some hormone-fueled teenage groping, but that was as far as it went.

This was the first time Bellatrix had ever seen another woman completely nude. Definitely the first time she'd been this turned on by another woman.

Nymphadora stood in front of her kneeling form, showing off her perfectly proportioned body.

"Like it?" Nymphadora asked, shaking her hips along with the very real cock that was now standing at attention between her legs. "I made it just for you, auntie," she breathed.

Bellatrix was completely lost as she stared at the jutting rod that had appeared out of nowhere. It was bigger than the Dark Lord's! Harder too... It definitely smelled better, she thought as she unintentionally inhaled its heady musk.

Bellatrix was shocked out of her trance when her niece slapped her across the face with her considerable cock.

"Oh, auntie! I love seeing my cock on your pretty face. You should see your expression. Don't worry, I'll fuck you while you watch this scene in a pensive later. Our first time, recorded forever~" she said teasingly.

Bellatrix lightly slapped her on the leg, pouting, "You know why we're doing this, darling. The house of Black needs to be repopulated! Don't embarrass me too much..."

Huh. Nymphadora had forgotten she'd added that kind of setting. To be honest, she had added so many small details to her auntie's mind that she could barely remember half of them. Luckily, she always did like surprises. They kept her on her toes! Life was always more fun with a little uncertainty!

"We're going to have lots of fun together, Bella," she said, rubbing the head of her cock against her face for a moment before moving her hips forward and sliding into her mouth.

Her new cock was so sensitive she almost came on the spot, just from the slightest hint of oral. Damn. Is this what men felt all the time? No wonder they were so obsessed with pussy. She could definitely get used to the new perks of her metamorphmagus powers.

Tonks had never experimented like this. She barely explored the possibilities of her inborn gift, too wrapped up in the stigma that it had painted on her back.

Bella was important to Nymphadora. In addition to her large magic reserves, she was a truly unique beauty. It was no wonder even Tom couldn't resist bringing her to bed. This was a woman that she wanted to add to her life, whatever shape it may take. She wanted to knock her up, and she wanted to bind them together, permanently.

That would all come later. First, she was going to make this slut gag around her cock like a cheap whore. All for the Black family, apparently. She could work with that.

Sliding her cock down her throat and trying to make her gag proved to be a challenge. Her throat was very resistant, and they were limited to her mouth, for now. Looks like the proper pureblood heiress had never learned to suck cock. Luckily for her, Nymphadora had plenty of time and loved to teach. Especially when her student was such a slutty little princess. 

It might require some effort, but she wasn't going to let anything stop her. Not when Bellatrix was so happy and willing to take her cock down her throat.

Nymphadora stared down at her aunt in pure unadulterated lust as she watched her cock sliding into her hot, wet mouth, deeper and deeper until Bella balked.

Not content with only having half her cock in her aunt's mouth, Nymphadora wrapped her fingers in Bella's hair, pulling herself forward. She thrust hard, forcing her cock into her aunt's throat, making the witch gag at first, but soon the elder Black woman had relaxed her throat, taking her full length in one inch at a time.

Bella could feel the hardness filling her mouth and throat. She surrendered herself to her niece's control, letting the girl skull fuck her as the urge to fuck overcame her. Bella was in bliss at being controlled like this, having her mouth being used as a surrogate cunt for her niece to bring herself pleasure.

Bella was loving the feeling of her niece's fingers running through her hair as she drove herself deep into her gullet. Before long, Nymphadora's cock started to expand. With a guttural moan, the metamorphmagus emptied her searing hot cum directly into her aunt's stomach.

After a few blasts were shot down her throat, Nymphadora relaxed her hold, allowing Bella to slide off her cock until only the tip was in her mouth. Bella moaned as she felt her mouth filled time and time again with her beloved niece's hot sticky cum, gulping it down as quickly as she could. Still, some gushed out of her mouth and fell into her heaving breasts.

As Nymphadora's climax was almost over, she pulled herself completely free from Bella's mouth, letting the last few shots of jizz splatter across her face and on her breasts, marking her as her own.

"Morgana's tits, auntie. That was the sexiest thing I've ever experienced," Nymphadora said hotly. Bellatrix moaned in response, nearly cock-drunk from the amount of cum splattered over her body.

Nymphadora swung her dick back and forth, reveling in the heavy sensation as it slapped against her thighs. This thing was so much fun!

"There's plenty more where that came from!" she promised, "I don't have any of the performance issues that plague wizards and men, alike. I can keep going all night long, baby. I bet I could pull off some crazy shit..." she trailed off, daydreaming about all of the sexual possibilities granted to her by her metamorph powers.

Nymphadora pulled Bella over to the bed, feeling up her curves and palming her ass as she went. She pushed Bella down onto her back, crawling between her legs and up her body, locking them in an embrace.

She pressed their lips together, both radiating an intense desperation. Bella hadn't been touched in over a decade and Nymphadora... In this life, Nymphadora was a virgin? Huh, that was a surprise. Tonks hadn't found anyone worthy enough to grace her bed, it seemed. Not that she had much to choose from in terms of men. To not be attracted to women in the world of Harry Potter? Poor girl. 

"That was fun for me, auntie, but now I want to do something that will make us both feel good..."

Nymphadora's hands rubbed circles over Bella's exposed nipples. The petite pebbles were puffy and raw, sitting atop her perfectly formed breasts. She played with them, making Bella squirm in arousal. Nymphadora couldn't resist any longer. She was going to lose her dick V-card right this second.

They were already in missionary position, hugging and kissing intimately, so Nymphadora only had to shift slightly to get things started. She rested the tip of her cock on Bella's slick folds, staring deep into her eyes.

"If you doubt that I can get you pregnant with this monster, I'll be more than happy to prove you wrong," she said. "I'm not going to go easy on you. By the end of the night, we'll have made more than enough progress with repopulating the Black family." she guaranteed with a sultry smirk.

"Toujurs Pur, right auntie?" Nymphadora whispered as she thrust her hips forward. She pushed her cock into her, and they groaned at the moment of penetration.

Bellatrix was frozen in shock, but only for a second. After the initial deep, nearly painful penetration, Nymphadora morphed her magical cock to match Bella's insides perfectly. The tip of her cock just barely brushed against Bella's cervix, teasing her and driving her wild with desire.

Her cock was a perfect fit for Bella's pussy, which squeezed around her and offered a tight, snug, wonderful pressure. It was perfect. She could slide her cock as deep as she wanted, she could rock her hips as hard as she pleased, and Bella took it all. Their compatibility was off the charts, though that was to be expected when Nymphadora could shift her cock to any size or shape.

She wouldn't ever be able to forget the pleasure she felt with every thrust, as well as the obvious impact it had on Bella. Bella might have agreed to this out of a desire to be pregnant, to rebuild her house, and get another chance at motherhood, but now her niece was giving her something else. Something she doubted her husband was even capable of giving her.

She was giving her a hard fuck, driving into her with all of the force, speed and skill she had between two lives. Bella was grunting in an unladylike fashion every time their hips smacked together, and she stared up at her lover with her mouth hanging open as if she couldn't believe what was happening to her.

"You really are an unfaithful slut, aren't you?" Nymphadora asked, sadistically. It never hurt to remind a woman writhing under you about her absent husband. Angry sex was the best.

Bella looked at her, surprised, "I'm only doing my duty to our house!"

Nymphadora chuckled, sliding her cock in and out of her aunt's pussy with deep, unrelenting strokes.

"Duty, huh?" she asked, "Was it duty that drove you to swallow my cum? I don't think a belly-full of seed will help you much with getting pregnant..." Bella moaned as she was forced to listen to her niece's filthy mouth degrade her.

"More importantly," Nymphadora began, "How are you feeling right now, auntie? Am I making you feel good? Do you like my girl-cock thumping you deep in your slutty pussy?" She thrust deeply and held herself there, mashing their tits together as Bella tightened in a sudden orgasm.

"You can say you're doing this for the family as much as you want, but I can tell you're feeling it. I want you to look me in the eye. Can you tell me you've ever enjoyed sex with your precious Dark Lord as much as you're enjoying this?"

Bella was lost. She'd never cum like this in her life. She'd thought she knew of sex and desire, but really she knew nothing. The paltry intercourse she'd suffered through before this couldn't even be counted as sex when compared to the vigorous lovemaking she shared with her niece.

Bella didn't answer, but she didn't really need to. Her moans were answer enough.

For the entire night, those moans never stopped. Nymphadora fucked her new lover into a near coma and imprinted their marathon lovemaking on Bella's mind, forever. They both lost track of how many times they finished, ending their coupling covered in each other's cum.

Even if Bella didn't get pregnant that night, she soon would be. Nymphadora had no plans of letting her leave Grimmauld place in the near future. She would live out the coming days as Nymphadora's live-in training partner and sex-toy. From their first time, she knew that neither of them would have any problems with the situation.

Nymphadora was determined to reunite her family. One bitch at a time.
