Chaldea Subjugation Organization (Fate/Grand Order)

Being called before her Master… Ushiwakamaru wasn’t entirely sure what to expect. To be fair, she wasn’t currently allowed to take part in combat. While she was still capable of fighting, and would be for a few more months, the Master of Chaldea had more than enough firepower at his disposal and had ultimately deemed the risk to her health to be too great for her to see a battlefield while she was… indisposed, as she currently was.
 
Blushing up a storm, Ushiwakamaru runs a hand over her growing baby bump, even as she smiles happily and continues to make her way towards her Master’s room. He had… he had gotten her pregnant. He’d bred her and placed a growing baby within her. Perhaps Ushiwakamaru should have been angry or disappointed over that, over losing her chance to fight.
 
In the end though, she just couldn’t bring herself to care. She was going to be a mother soon, and that… that spoke to her in a way not even her life of fighting did. She had always been a samurai above all others… but now Ushiwakamaru would be happy being a mother first and foremost, and her Master’s dutiful, adoring Servant second. Licking her lips as she comes to the door of his room, the brunette reaches out and knocks tentatively. When the door opens on its own a moment later, she steps inside.
 
There’s no one to greet her, at least not at the door. As it closes again behind her, Ushiwakamaru freezes in place, staring with wide eyes at the sight before her. Her Master is there of course. He stands off to the side, one hand in his pocket and the other nursing a glass of some drink as he smiles slightly, clearly pleased with her reaction.
 
But her eyes aren’t on him. No, her eyes are focused on the other woman in the room instead, and she finds her heart beating rapidly in her chest from sheer excitement.
 
“Greetings, Minamoto no Yoshitsune. I have heard much about you from our Master here.”
 
S-She knew Ushi’s name. Minamoto no Raikou, Ushiwakamaru’s famous, Oni-slaying ancestor… she knew her name. She addressed her by it, and all the pregnant Servant could do was stand there, mouth dry as her legs shook a bit, wobbling around the knees from sheer nerves combined with pure joy.
 
“Y-You… you…”
 
Raikou smiles and nods, as if understanding Ushiwakamaru’s plight.
 
“Yes. It is me. Please, come closer. Let me see you.”
 
How can she say no to such a request? Just being allowed to be in the proximity of such a venerated heroine from Ushiwakamaru’s own bloodline leaves her feeling abuzz with happiness. Stepping closer, the samurai blushes deeply as she realizes that she and her ancestor have something in common. Raikou sports a baby bump as well as she sits there with her knees under her on the Master’s bed. She smiles widely when Ushiwakamaru finally sees it, bobbing her head up and down.
 
“Yes, Master has given us both a gift, hasn’t he? Ah, but even if we are to both be mothers soon enough… I would like it if you called me Hahaue.”
 
Ushiwakamaru’s eyes nearly bulge out of her skull at the very thought of being able to call the woman before her any form of ‘mother’. Her blush grows even more impressive as she sharply nods her head up and down in agreement. Raikou’s smile widens into a full-blown grin, especially when Ushiwakamaru ducks her head and shyly responds with an affirmative.
 
“Ah… a-alright, Hahaue…”
 
“Hmph, I suppose in that case you should call me Aniue, instead of Master.”
 
Ushiwakamaru’s eyes snap up towards the Master of Chaldea where he stands off to the side. He’s smiling as well, but even if he’s teasing her a little bit, she can also tell he’s rather serious in the same breath. He truly is okay with her calling him ‘big brother’. And as she stands there between the man who impregnated her and her wondrous, amazing ancestor, Ushiwakamaru can’t help but agree, though she does so with no small amount of embarrassment, a bright blush across her features.
 
“Yes… y-yes, of c-course… A-Aniue.”
 
Only then does Shigure walk forward, setting his glass down behind him before he does so. He reaches her where she’s standing next to the bed that Raikou is sat upon, and he reaches out and pats her head gently. Ushiwakamaru can’t help but flush, but this time in pure enjoyment as she nuzzles into his palm, bumping her scalp up into his descending head pats. She likes them… s-so what?
 
“That’s a good girl. Mm, I think you deserve a reward. Don’t you agree, Hahaue?”
 
As he calls Raikou mother as well, Ushiwakamaru turns her attention towards her ancestor… and goes wide eyed all over again when the flushed and aroused, purple-haired beauty reveals that she’s exposed herself while they were distracted. Raikou is now topless as she displays her full, bountiful chest proudly, her beautiful breasts both bouncy and rather firm as they make a good show of defying gravity despite no longer having anything to keep them in place.
 
“I agree, beloved son. Come here, Ushi. Come and sit on your Hahaue’s lap.”
 
The implication of what she might do once she obeyed was obvious, especially since Ushiwakamaru could see little white droplets leaking from Raikou’s exposed nipples even then. Still, she happily obeys, climbing onto the bed and into Raikou’s lap as the more developed Servant takes hold of her and pulls her in close. A gentle but firm hand slides through Ushi’s brunette locks as Raikou palms the back of her ‘daughter’s’ head, and the next thing she knows, she’s being pushed down to the other woman’s full, lactating breast.
 
Ushiwakamaru has no reason to resist though. At Raikou’s urging, she happily leans in and takes one of the nipples before her into her mouth. Suckling at it, she gets more than a taste of Raikou’s breast milk, moaning happily as the sweet, thick fluid slides right down her throat, nice and easy. Swallowing some more, Ushi finds herself happily beginning to drink from Raikou, even as the other pregnant Servant holds her close.
 
Their baby bumps rub against one another as a result of this of course. While Raikou has bigger breasts, Ushiwakamaru actually has a bigger belly for the time being, proving she’s further along then her ancestor… her mother. This thought causes Ushiwakamaru to feel strange, like she doesn’t know if she should be happy or not about it.
 
But maybe it’s not a matter of happiness or sadness. Sometimes, it’s okay to just be content with one’s circumstances. And if there’s one way to describe Ushiwakamaru’s current feelings, the brunette is quite content and supremely satisfied to be sitting in her ancestor’s lap, slurping from Raikou’s breast, drinking down her Hahaue’s milk as she presses her pregnant belly up against Raikou’s own burgeoning midriff.
 
For a time, she loses herself in that set of feelings and sensations. What else is there? Ah, but she’s forgotten the third occupant of the room, its owner at that. She only remembers her Master, only remembers her ‘Aniue’ when she suddenly feels something poking at her from behind. Her petite little butt cheeks have been pulled apart, and the Master of Chaldea is now rubbing against the rosebud of her asshole.
 
Ushiwakamaru pulls away from Raikou at that, looking back at Shigure with a trace of fear in her gaze. He’s got nothing but a kind smile for her though, and a look down at his cock shows it to be rock hard… but also glistening. He’s lubed himself up in preparation for penetrating her back door. It’ll be the first time Ushi ever had anything back there, and to say she’s nervous would be an understatement.
 
But Raikou isn’t about to let her squirm away out of misplaced fear. The purple-haired woman pulls Ushiwakamaru back to her breast with a firm strength that she might have been able to match, but in the end chooses not to. As she directs Ushi back to drink from her once again, Raikou makes soft, comforting noises and speaks in a quiet, calming tone.
 
“Shh, shh… it’s okay Ushi. Just let Hahaue and Aniue spoil you, alright? This is all about you.”
 
She couldn’t help but believe that. It certainly felt like it was all about her in that moment. As Aniue began to penetrate her from behind, Ushi couldn’t do much more than whimper and mewl into Raikou’s breast. All the while, she kept on drinking, even as her Master, her ‘big brother’ slowly penetrated her back door, inch by inch.
 
There was no pain of course. Not even really discomfort, in the end. Instead, it was more of a pressure then anything else. Pressure beyond anything Ushi had ever felt before, but not an unpleasant sensation, altogether. Aniue’s cock had always felt good though, even before he’d suddenly, abruptly become her big brother. Master’s member had been what impregnated her, in the end.
 
Ushi could still remember their first meeting. She knew that Master had used his Command Seals to awaken her more perverse side, and she didn’t blame him at all for that. He’d shown her the joys of being a woman and given her the gift that only a woman could be given and only a man could give. She was growing heavier and heavier with his child now, and that… that wasn’t something she could ever truly be unhappy about.
 
But now his cock, the same length that had filled her womb time and time again until they found out she was going to bear him children wasn’t inside of her cunt, but instead her back door. And he kept going too. Just when Ushi thought that he would be done, just when she thought he’d find the deepest part of her, or that his cock would run out, he pushed in another inch.
 
His dick HAD to run out, right? Of course it did, and in the end, she felt it as his crotch pressed against her buttocks and his balls slapped gently against her dripping wet pussy lips. By this point, Ushiwakamaru was on her knees rather than truly held in her ‘mother’s’ lap. Her ‘Aniue’ had gently pulled her into position, and now, while she was still drinking from Raikou’s tit and pressing her belly bump against the other Servant’s, she was also jutting her thin hips and her petite buttocks out towards the man behind her just a tad, his cock filling her ass beyond what she would have ever thought possible.
 
As he pulls back out just as slowly as he went in, Ushi experiences a whole new type of pleasure, her eyes going crossed as she moans but continues to drink Raikou’s milk. It’s strange that him removing his cock would feel good too, but maybe its just the changing of the sensations, the juxtaposition between being full and being empty.
 
Regardless, he doesn’t pull all the way out. After a moment, Aniue pushes back into her and then begins to speed up the whole process. He still takes it slow of course, but what follows could more generously be called thrusting then his original push and pull technique. Ushiwakamaru moans into her Hahaue’s breast of course, the sound muffled by her mother’s teat, even as her big brother fills her in such an exciting new way.
 
Ushi could never have guessed that it would feel this good to have a big fat dick up her butt. If she’d known… well, it would have been a toss up whether she would have asked for it earlier than this or not. Truthfully, she was still not quite confident enough to beg for sex like some of Master’s more amorous and more adventurous Servants. Their relationship had started off with him having to rely on Command Seals to convince her that she wanted him as much as he wanted her after all, and that would always be there.
 
But she did so love to be of use to him. She loved to be his in whatever way he needed. In the beginning, it’d been equal parts sex and fighting. She’d fought for the Master of Chaldea to the best of her abilities, like all the Servants he summoned. But then she’d gotten pregnant, and now she was only truly able to make him happy with her body rather than her martial skills these days.
 
He didn’t really hold it against her though, and for that Ushiwakamaru was grateful. Introducing her to her ancestor, introducing her to this new type of pleasure, e-even having her call him ‘big brother’… all of these things contributed to Ushi’s happiness as his gentle but deep butt-fucking finally pushed her over the edge. Her squeal is mostly stifled by Raikou’s soft boob flesh as she jerks and shakes in between the two other people occupying the bed. Her pussy juices squirt from her cunt lips and spray across Raikou’s own body as the purple-haired woman coos happily for Ushi, only holding the cumming girl closer.
 
Of course, that’s not the end of it, even if her anal passage DOES squeeze down all the tighter around Shigure’s dick. He’s far from finished with her, and what follows is more of the same. Not in a bad way… but instead in a very, very good way indeed. Ushi drinks from her ‘mother’s’ breast as she gets butt-fucked, she swallows down Raikou’s delicious milk even as a bit of her own leaks out of her smaller titties. She slurps and drinks of her mama, all while getting pounded from behind by her big bro.
 
And honestly, there’s nothing Ushi would want to be doing more in that moment. In truth, it’s lucky that she’s hardier than most mortal humans. Lucky that she’s a Servant instead of a normal run of the mill girl. She might not have been able to handle everything that her body was put through. In this case, Shigure was being more than gentle enough with her ass for that not to ever be a problem, especially with how he’d lubed up the entire length of his cock before beginning this exercise.
 
However, the truth of her endurance and stamina lay more in the drinking of her ancestor’s milk than anything else. Her ‘Hahaue’ had been holding her to the same nipple for quite some time now, and it was a sign of just what the two of them both were that Raikou had yet to run out of breast milk, and Ushi had yet to feel even remotely fuel. They were Servants, weapons after a fashion. Weapons capable of getting pregnant it seemed, but still heroic spirits meant to be used for battle.
 
This of course led them to being very efficient in terms of energy use. Raikou’s milk filled Ushiwakamaru’s mouth and poured down her throat, but it never quite managed to fill her belly, as her body instead absorbed the nutrient, prana-filled liquid and fed it back into her own energy pool, giving her even more for the baby growing within her. Of course, Raikou had more than enough to spare as well, but this did still result in the purple-haired, top-heavy, voluptuous woman that had commanded Ushi to call her mother ultimately growing tired at around the same time as Ushiwakamaru herself did.

After a butt-fucking that seemed to last hours, after cumming over and over again as her anal walls clenched and squeezed as hard as they could around her big brother’s dick, Ushi’s head was finally pulled back from a slightly tired Raikou. But Raikou was still smiling in a lewd, perverse manner as she cupped Ushi’s younger-looking face with her hands and cooed at her.
 
“Such a sweet, sweet daughter… such a good girl. Give mama a kiss.”
 
How can she say no? Well, she doesn’t even really get the chance in the end. Raikou is ultimately the one that initiates the kiss, capturing Ushi’s lips and slipping her tongue into the brunette’s nonresistant mouth with an eagerness unmatched by anyone Ushiwakamaru has ever been with before. Even her Master… her big brother’s kisses had never been THIS enthusiastic before. Raikou truly was a deviant sort of mama, that was for sure.
 
Still, Ushi doesn’t try to pull away. She happily leans into it in fact, and it’s not long before the sight of two of his beloved Servants, both pregnant with his child, sends the Master of Chaldea over the edge. Ushiwakamaru feels it immediately of course, she feels his seed flooding her back door, feels it as her ‘big brother’ busts a nut in her butt.
 
It sends her through one last explosive orgasm as it happens, and Ushi’s eyes roll back in her head even as her body shakes and spasms, causing her pregnant belly to bump against Raikou’s again and again. Her anal passage milks Shigure of every ounce of his seed before she finally slumps forward into Raikou’s embrace entirely, completely and utterly exhausted.
 
Raikou lays back at that and takes Ushiwakamaru with her. The more petite of the two servants ends up with her head resting on Raikou’s massive, pillowy breasts, and their pregnant bellies press against one another as she lays there across Raikou’s far more voluptuous and matured form. She really can believe in that moment that Raikou is her mother. As her Master settles down beside them and runs a hand along her sweaty back, gliding his fingers across her trembling flesh, she can also believe he’s her big brother too.
 
As Ushiwakamaru starts to pass out, she manages to get some words through before doing so. She moans them quietly, but their intended recipients hear them nonetheless.
 
“Love… l-love Hahaue a-and A-Aniue… love y-you lots…”
 
That gets smiles and chuckles from both of the bed’s other occupants, and Ushi herself smiles as well, even as her eyes finally drift shut from pleasurable exhaustion and oblivion takes her.
