[Semi-Twinning, Roleplay, Filth]
"Happy Birthday, Blair."
A little music box started to play a dainty tune as the white-haired keeper of the Forbidden Archive smiled towards her guest. Not that she bothered dressing up for the occasion, she was still clad in her usual robe with the same silly eyepatch that she liked to wear whenever she was getting nice and cozy.
But it was still a bit of a special occasion. Her guest, her patron, her good friend and continued supporter, the almost ethereal Blair, was celebrating their birthday once again. It marked the start of a brand new year for their continued partnership, a year that would be filled with the two ruining their favorites again and again and again. As they had done over the last year, and the year before that.
"...That's it?" Blair asked as they tilted their cute dark-skinned and frizzy-haired head. "Just happy birthday? You're that busy?" They continued, pouting a little. Not that they had been expecting any sort of big gift or anything, but they were expecting something. Maybe a kiss. Maybe even a hug. So it was a little strange to not get anything besides congratulations...
Hato narrowed her exposed eye a little as she turned around in her chair, gently looking at the massive stack of books on her table. As well as the stack of games that were collecting dust, and then the computer in the corner that was currently blowing out so much dust that it was almost impossible to think. Well, if you weren't used to the sound.
"I mean you can see how much I'm working on." She muttered as she quietly took a sip from her cup of coffee. "Yours is somewhere in there too. You wouldn't want me to avoid working on all that good horny stuff that you've been waiting for, right?"
Blair nodded a little. Yeah, Hato needed to finish all of her work before they could truly play. But she would honestly never finish if she never bothered to try and just have a bit of fun. And since it was their birthday, it meant that they were the ones setting the pace. "I guess, I guess. Can I just ask for one thing?"
Hato paused. She knew better than to give them an inch. The last time they gave them an inch, the whole archive ended up ruined and she had to pull Mikai out from one of her stories so she could try and clean the damn place up. But at the same time, she did feel a little bad over practically just giving her nothing as a real gift. Which prompted her to let out a sigh and slowly look towards Blair. "Alright, what's-"
She didn't even get to finish. Blair immediately launched forward and planted their succulent and plush lips right up against Hato's own, letting their tongue slip in through those lips so she could cover the inside of the sweet writer's mouth with their saliva. All while pouring lots and lots of their essence right into her. It's fine, she could handle this kind of treatment. She was a durable sort. Definitely the type that wouldn't fall prey to any sort of temptations!
Hato should've seen this coming. She had specifically anticipated that Blair would do something once she gave them a chance. But here she was. Underestimating them, and getting filled by all sorts of horny energy as a result. Concentrated horny energy too. The kind that very quickly filled her mind with all sorts of dirty ideas that hadn't yet been carried out. Ideas that were begging to be made a reality. Not through text, but through action.
As she absorbed more and more of that energy, her body started to change at the same time. And the most egregious change came in the form of her attire. Her robe tightened up as it transformed back into her favorite suit, only for the top to quickly tighten more and more until the fabric became little more than an excessively tight net that dug into her fat tits while leaving behind big red marks that wouldn't fade even if she managed to get it off. Her pants remained the same, though they quickly grew extra tight as well thanks to something thick growing between her thighs, something so thick that it was threatening to pop open the buttons and release itself into the world.
Hato let out a moan as she pulled herself away from Blair for a few moments, with her skin quickly growing nice and thick and dark as she drew fresh breath. The same dark tone as Blair's skin, with her lips puffing up until they were just as puckered as her favorite ethereal friend. The darkness spread further across her form, turning her from a pale albino into an exotic beauty, especially once that dark tone spread all the way down to her thighs...
The button that kept the bulge pinned within popped open and revealed Hato's brand new Big Black Cock, which was even bigger than the one between Blair's thighs. It only made sense, considering Hato was way more stacked than Blair could ever hope to be. So naturally by absorbing parts of their essence, she'd end up a reflection of her good friend in more ways than one. While at the same time being exaggerated in just the right kind of way.
The last change that stood out after Hato had absorbed all of that delicious stuff from her friend's horny heart, was the way that her hair started getting all sorts of messy while turning the same hue as her friend's. Still tied into a somewhat clean and composed braid, though nowhere near as well groomed as before. Not that she needed to be well groomed, especially not since she always shut herself away inside this crummy archive.
"You..." Hato, trembling a little as she managed to keep herself intact despite the essence trying its best to change her. "You really just want me as a gift for your Birthday, don't you, Blair?" She muttered, already having figured out why they would bother going through all the trouble of transforming her this intensely.
Blair giggled and wrapped their arms around their loving friend, burying their face right inside those extra dark and thoroughly netted titties. "Of course I want you as my Birthday gift, aaauntie." They chimed, licking their lips as they gave both of those big titty poppers a nice kiss.
Hato trembled a little more as her brain rewired. Duh, of course her sweet little niece would want nothing more than to be spoiled by her. Her adorable niece was always meant to be spoiled by her. "Well, if that's what you want, then why don't we change things up a little? I'm sure you like little ol' me, but you like many more cuties than me. And I'm sure we can fill their roles for one day."
Just like that, the world around them started to fall apart, as both of them started to close their eyes...

"I can't believe you'd try and steal my Gungnir, Maria!"
"It's not your Gungnir, Tachibana!"
Hato had put her powers to good use. Pulling both her and her adorable Blair into a story they were both familiar with. The story of the Valkyries that fought with the power of song. Letting them both fill a role they adored.
Tachibana Hibiki, the heroine of the story, was now played by the excessively curvy Hato. Which resulted in her uniform struggling to contain all of that dark meat that had grown. Especially the meat that was currently pressing against her fellow heroine's face, the big black cock that was just throbbing with every breath she drew.
Maria Cadenzavna Eve, the former enemy turned close ally, was played by Blair. Who just couldn't help but drool a little as she looked straight at that magnificent slab of black meat. Her 'Black Gungnir' really didn't compare to the kind of cock that 'Hibiki' had. The true 'Gungnir'.
"It's mine!" Like a brat turned desperate, 'Hibiki' couldn't take it any longer. She lifted her cock up ever slightly, and then slammed it straight into her ally's mouth. In and out, in and out. With the kind of fury that only somebody like her could put out. The same kind of fury that would result in her turning Berserk if she wasn't careful.
'Maria' gagged as she felt that cock shoving down her throat. On one hand, the part of Blair that was busy enjoying these types of plays loved the sensation of getting her Aunt's cock straight down her throat. It felt so good that it was only natural that her throat would tighten around it. But the part of her that was dedicated to playing the character was not having as swell a time, especially not as the thickness of that shaft was making it hard to truly fight back against her.
Especially as 'Hibiki' started to lick her cock to make it grow just as erect as hers. Her 'Gungnir' was nowhere near as big as her ally's, but it was beyond sensitive. So much so that as soon as it slipped right into the heroine's mouth, she could feel the hot cum pouring right out.
'Hibiki' swallowed the cum that poured from the tip of 'Maria's cock, all while slamming harder. Her dark skin turning red as she grew more and more Berserk, with her eyes widening as she popped her head off that smaller 'Gungnir' with a loud howl...
*BRAAAAAAAAAAAAAAAAAAAAAAP*
And a despicably loud and brassy sound leaving her lips, all while 'Hibiki' drooled like a beast. The foul smell of her Berserk state wafted out through their shared bedroom, as 'Maria' was forced to inhale as much of that deep red and extremely stinky gas...
It was burning away at her insides as she inhaled it. Such a pungent scent. So strong that she couldn't stop herself from cumming again. D-Damnit, Tachibana. Why did she have to have defeated her by pinning her down with her fat ass? Now she couldn't get enough of that foul smell...
As their play started to diverge, the beastly 'Hibiki' just giggled like a horny beast and continued to hump away at 'Maria's mouth. All while her farts just kept on blasting out again and again. Repeatedly firing out and burning more and more of her ally's sane mind the longer she was allowed to remain dominant.
It was a total and utter mess. With the dominant and beastly form that Hato took being far too much for Blair to handle. But the dear Aunt had already taken this into account. She wasn't going to remain dominant for the entire duration of their time together. It was their Birthday after all.
So as another destructive *BRAAAAP* echoed out, their eyes closed once more as they were pulled into yet another story...

"Well, Joker? Do you like what you're seeing?"
'Joker', played by Hato yet again, was doing his best to look upon the muscled beauty that was sitting on top of his waist. When he first romanced her, he was way bigger than her. In every single way. It was actually something that he tried to help her with. Allowing her to grow bigger and stronger so that she could pay him back for everything.
He just didn't expect 'Makoto', as played by Blair, to end up with so much muscle that she was almost twice his size. Not only that, but the sheer amount of muscle had turned her tits into pecs. She was more manly than he was, though that wasn't exactly hard considering his big fat black titties were always struggling to stay pinned within his uniform.
'Makoto' licked her lips as she slowly stroked the massive cock that was currently pressed against her stomach. That was the other thing that had grown bigger since she started working out. That massive manhood was her pride and joy. So much so that she put her arms behind the back of her head and thrust her cock forward, spraying a bit of cum straight onto 'Joker's face without as much as a single moan...
'Joker' wiped a bit of the cum away from his face, though he just couldn't stop looking up at that massive slab of muscle that 'Makoto' had become. "...You mind if I..:" He started muttering, because he actually kinda did want to top that living amazon. He wanted to see if he could conquer her, at least once.
He didn't get the chance. Especially not as his cock, which was already very impressive on its own, was practically swallowed by the gluttonous hole between 'Makoto's tight cheeks. An act that forced the young man to cry out in sheer delight, his eyes rolling into the back of his head.
"C'mon, Joker! We've only just started! Let's make this a workout, I'll make sure you get nice and fit so we can just wipe Mementos clean together!" 'Makoto' grinned as she bounced up and down, the sheer weight of her muscles quickly slamming down on those fragile hips down below. Not that she intended to harm her boyfriend, it's just what happened when she got this excited.
While the part of Hato that was busy playing her assigned character was not exactly pleased with the sensation of having her thighs crushed by a muscled maniac, the part that loved seeing the fruits of her efforts as an Aunt? Oh, she loved every moment of it. Sure, it hurt like a bitch, but what didn't hurt in the pursuit of love?
'Joker' let out moan after moan as he was forced to cum and cum over and over. He didn't get a chance to take a break or catch his breath, he was just forced to cum into that greedy ass again and again. All while making 'Makoto's belly bloat out, while keeping the bloated surface as muscled as ever. It was like he was being drained for nothing more than a simple meal, when he knew that she really did love him and this was just her way of showing it.
"Come on, Joker! We've got plenty of reps left! And when we're done, you can pin me down and put your new leg strength to good use!" 'Makoto cried out, more than happy to thoroughly tenderize the boy she loved. But at the same time, all that muscle... Mmmph, it made her want to swap their roles out again.
And her wish would be granted, as they were sucked out of these roles and into brand new ones as a new story began, at the exact moment both of them started to cum...
---
"I finally managed to pin you down..."
"So, what are you going to do? You think you can defeat the 3rd Espada with nothing but your ass?"
"You of all people shouldn't underestimate me. I'm Captain for a reason."
"Show me then. Show me why you're a captain, boy!"
Once again, the two were locked into a new kind of play. This time with Hato on top, with her excessively feminine form being used for a Shota's role instead of a young man's. Then again, her fat ass would be more than enough to fill out this role. Blair, on the other hand, was once again playing the role of a muscled woman, though the one they were currently playing wasn't exactly the same kind of muscled mess that Makoto was.
Captain Hitsugaya Toshiro of the 10th Company was the role that Hato was currently engrossed in. And though she hardly looked the part, she had the bratty nature down pat. Especially with his glare down at his opponent, who just remained calm and confident that he wouldn't be able to properly defeat her.
Tier Harribel. The 3rd Espada. That's who Blair was playing. A real sexy opponent, who didn't falter despite the fact that she currently had a fat black ass staring her right in the face. No, if her opponent was going to show her any sort of mercy or falter in any fashion, she would strike. Delivering a fatal blow to that hole and ensuring that he couldn't recover...
"Bankai." *BRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAP*
Or so she thought. The Captain had a deadly trick up his sleeve. A fart so cold that it was impossible to fight back against. A fart so cold that her body was immediately frozen solid, right as she started to stick her tongue out so she could lick away at that hole and disable him...
As far as 'Hitsugaya' was concerned, unleashing the true power of his ass in this way was more than enough to destroy the Espada. Though there was the caveat that even he ended up freezing partly, gasping and panting as he had to reach down and slowly break off the frozen cum that was stuck to the tip of his cock...
Right before he felt a warm hand grab ahold of his wrist, and heard a soft chuckle. "Is that really all, boy?" 'Harribel' mocked the boy, as she grabbed ahold of his frozen cheeks. "You'll have to do better if you want to defeat me. Such a weak fart won't be able to make yours..."
'Hitsugaya' smirked. Just as 'Harribel' did. It seemed like the two had truly met their match. Even though she was able to overpower his freezing fart, the way that her own cock had started to drool the moment she was freed from the ice meant that she would fall if she managed to cum a few more times while being frozen.
It was a test of endurance. Whoever could last the longest would be the winner... And the one who gave into their pleasure would be the other's slave, nothing more than a sponge soaking up all the after effects of using their power.
And once one of them managed to win, Hato and Blair would move onto their next play. And so on, and so forth, until the day would come to an end. Only then would Hato be able to turn back and avoid responsibility as an Aunt.
But until that time came, she’d indulge her sweet little Blair and make all their horny delights come true...
