A commission from aryion.com/g4/user/Cactaur98 who wanted Jeanne snacking on a certain alter they can't stand as well as a infamous pink-haired cross dresser. Much to poor Jeanne's dismay.

also for anyone wondering about the Hussites comment this is why.

Jeanne, you have to eat your embers, or you're never going to get stronger, and we need you for dealing with that bratty bitch BB." Ritsuka sighed as he held up a magic silver star.
"Master, I understand that you think I'm that valuable, but surely there are better servants than me, that XX, for example." the saint brushed her long golden braid to the side as she tried to be modest.
"Your stuns are pretty damn valuable as well. You'll be useful now that your NP doesn't stun you anymore!" the young mage grumbled in frustration. He was already in a bad mood and having Jeanne denying her needed accession in favour of useless servants like the Phantom, Mata Hari and anyone, but her only increased it.
"Master, may I ask how many embers you even have?" the holy maiden asked calmly. The young man was silent for a minute before groaning angrily.
"FUCK!"
"No need to swear Master," she placed a dainty yet strong hand on his shoulder as the young man shouted bitterly. The mage slowly rose from the floor with a wicked grin that sent a shiver up Jeanne d'Arc's spine. He mumbled something she couldn't hear.
"What was that Master,"
"Extras," the mage grinned evilly.

The mage called all his spare servants to him. Due to the nature of heroic spirits, there could be many of the same person summoned to the same grail war or in this case, summoned to Chaldea. Not all of the spare servants were happy about being sacrificed to power up the saint, but most were shockingly calm about it.
"Alright, Jeanne, we'll just turn them into mana and be done in a bit." the mage smiled. The speaker blared to his mind.
"Um, the converter isn't working," a feminine voice called.
"Well, what the hell are we supposed to do?" Ritsuka snarled. A sinister grin crossed his face, Jeanne shuddered nervously.
"Jeanne, how hungry are you?" the mage turned to her grinning.
"Why?" Jeanne trembled weakly. She didn't understand what he was getting at, but it sent a shudder down her spine.
"Well, embers tend to be eaten. Spare servants are just a different sort of ember." Ritsuka smiled.
Jeanne let out a cry of horror at what he was insinuating.

She had no idea how many servants she ate. Some reluctantly, some who threw themselves down her throat and some who were force-fed to her. She pleaded for their forgiveness from each person shoved down her gullet, some more than others. Despite her pleas, her stomach reduced the heroic spirits to mana exceptionally fast, the screams, the moans, it was all silenced quickly. But as a new figure entered the room her blood ran cold.
"No! Not her! Anyone but her Master!" the saint screamed to the loudspeaker "Why her!"
"Somehow I pulled six of her, not sure how but I did, and I don't need a spare. I mean, the possible threesome I could have would probably be amazing, but I could do that with basically any servant. So it's not a big loss." Ritsuka's cheerful tone rang over the speaker, it unnerved the saint.
"I hate that I have to do this. I tried to burn this idiot, but you assholes have a ton of servants that can benchpress me with one hand. So I don't get a say in the matter. "before the saint was herself but with white hair and pale skin dressed in black armour. Jeanne whimpered weakly as her other self was shuffled over to the saint.
"Just hurry up and get this over with you sanctimonious pain!" Jeanne Alter snapped as her armour vanished with a golden shimmer leaving her in a tight black dress. Alter moved her hands towards the saint's mouth, it widened without her intention. Alter's hands slipped into Jeanne's mouth, Jeanne couldn't help but savour the succulent taste of her other-self. Alter was slightly greasy, she reminded Jeanne of pork, fatty yet enjoyable with a bounce to her flesh. Alter's wrists passed through the saint's jaws, her teeth scraping across Ater's flesh. She knawed gently at the soft flesh under her teeth as Alter's elbows passed into the hungry maw.
"Damn saint! Ater hissed as her body slowly disappeared down the saint's throat.
"I'm sorry sister. Please forgive me for what I must do. For what is required of me to become strong. I will do what I can to make sure the you who does reside here is taken care of. I will protect the other you who lives here even if you hate me." Jeanne mentally prayed as Alter's head was forced into the saint's mouth.
"I come to Chaldea, and this is what I get? Bastards, I'll burn you all at some point!" Alter hissed as her head was forced into the pulsing gullet. Her body slipped deeper into Jeanne's jaws, her rage added a barbecued flavour to the Alter, Jeanne could almost taste the grease cooking off of her with nothing more than Alter's pure hatred.
"Why does she have to taste so good? This isn't fair. I'm sorry sister." Jeanne grabbed her other self's body to assist in consumption. Her hands ran across her evil self's soft skin, a hand caressing her plump rear.
"Am I really this......ample?" Jeanne questioned with a squeeze.
"Stop that, you idiot!" Atler snarled but her rage only added to her flavour as the saint groped her further. Alter's soft breasts popped into Jeanne's maw only to be greeted with teeth knawing on them.
"Damn it, you idiot! Even I didn't know you were a hopeless lesbian! But stop groping me!" Alter screamed, her legs began to flail in useless fury.
"Someone, tell me we're recording this." Ritsuka smiled as he watched the display.
"Yes, Senpai. It's being recorded. Sheba said something about selling copies." Mash stuttered as she covered her eyes with her hands but still watched through her fingers.

"Does this count as sex before marriage or masturbating? Either way, I should pray for forgiveness after this." Jeanne thought to herself as she engulfed the other her up to her thighs.
"This is the most degrading, disgusting thing I've ever experienced." Alter sobbed her spirit broken in disgrace. Jeanne used this to pull the evil her deeper, she savoured the soft flesh of the other her's ass as it scrapped across her teeth. Alter flailed weakly, but it didn't stop the ruler from devouring her. Soon all that remained of the rage-filled what if that was Jeanne Alter were her wriggling feet before they two vanished down her pure-hearted self's throat.

Jeanne let out a thunderous belch as Alter was deposited into the ravenous stomach. The enraged Alter could already feel the mana being sapped from her. The acid burned at her skin with every passing second.
"Damn you Jeanne D'arc, damn you Chaldea and damn you Ritsuka Fujimaru! I will burn you all!" the evil saint roared with every once of her endless rage.
"I'm sorry sister. Though it may not seem it, I am sorry this had to happen. I will make it up to you." Jeanne rubbed her engorged stomach, trying to ignore the wriggling from the angry anti saint.
"Am I done? Surely you don't have any more servants to feed me?" she whimpered weakly to the loudspeaker in the corner of the room.
"Don't worry, there's just one more. Then you can relax." the mage's tone was calm and relaxing as the door slid open revealing a girl with a long pink braid and a short black skirt with a matching tight shirt. There was only one problem with her. she was a man by the name of Astolfo.
"No, anyone but him!" Jeanne shouted in frustration.
"I know you only have the one of him! You can't sacrifice him!" the saint bellowed to the speaker.
"You are one hundred percent right, I just don't like him. He creeps e right out." the mage chuckled over the speaker as Astolfo sauntered into the room with a smile.
"Wow, way harsh Master, but if I got to feed the Saint of husbando stealing than so be it." Astolfo shrugged casually as he skipped over to Jeanne.
"Has it ever occurred to you that Sieg just didn't like that you have a dick?" Jeanne snapped in a moment of anger. She knew Astolfo from more than just Chaldea. The two had fought in a holy grail war in another timeline and had both vied for the affection of a homunculus named Sieg who in the end had chosen Jeanne over Astolfo. The two had never gotten along as a result. Jeanne hated to admit it, but in her heart she truly detested Astolfo, she found him crude, obnoxious, annoying, and overall repulsive, not to mention most of what he said bordered on utter nonsense.
"Everyone should try Asolfdick at least once. It can't hurt to try. Besides, he could have put his in me if the series hadn't wimped out." Astolfo smiled despite his nonsensical statement.
"What does that mean?" Ritsuka and Jeanne both groaned in unison.
"Oh please, like you haven't broken the fourth wall for an event Gudako." Astolfo turned to glare at his master through the camera that watched the unfolding events.
"The hell is a Gudako? See, this is why I'm getting rid of you. You irritate me with all your nonsense. Just do Chaldea a favour and please die!" Ritsuka seethed as he spoke, for reasons even he couldn't explain he detested Astolfo.
"There are worse servants to end up being eaten by than Joan here. I mean, I could end up as Jack's food." Astolfo laughed.
"I wouldn't feed you to my daughter if it was my last resort!"
"Ya, ya. Alright, Jeanne, hope you're hungry because here I come." thee rider began to walk to the other side of the room putting the room between the two servants before suddenly sprinting full speed at Jeanne.
"Wait, what are you doing!" Jeanne screamed in horror as the rider leapt into the air with a smile.
"CANNONBALL!"

Jeanne collapsed to the ground in pain as Astolfo literally threw himself down her throat.
"Hey, come on, surely you're not going to choke now, are you? Astolfo's voice sent excruciating ripples through the saint's throat. She had eaten many servants whole today, but this was unlike any of the others. Some may have had large breasts, but they were still laying flat when they slid down her throat, but Astolf's entire body was now curled into a ball in her throat. She gagged in pain as he squirmed in her gullet, she tried to scream around Astolfo, but all that escaped was pained gargling.
"Come on, Joan, my ass can't be that big." the rider laughed, ignoring Jeanne's pain. Momentarily, ignoring, the agony in her throat Jeanne clenched her fist, raising it high as she made sure she would hit her target. With thunderous strength that would be expected of a heroic spirit with B rank strength, she slammed the fist into Astolfo's spine. The paladin screamed in pain as his body shot down her throat. Though her attack failed to send him completely to his impending fate, she brought a second slam to finish the job as Astolfo tumbled into the waiting stomach.

Jeanne Alter looked up to the pulsing gullet t see what the wretched racket was, but her curiosity was answered as the pink-haired rider crashed against her face.
"You idiotic harlot!" Alter howled clutching her nose in pain. Astolfo rubbed his back as he fumbled to get some ground in the soaking pit.
"So, hows the new room bestie?" the paladin grinned to his roommate. Alter froze as she realized who would be with her in her final moments.
"This is cruel and unusual punishment! Digesting me is bad enough, but you had to stick me with this pervert?" Alter wailed as she beat weakly at the stomach that encased her burning flesh.
"honestly I know I should feel repentant for what I just did to sir Astolfo, but I don't. Honesty I feel like I just did the world a favour." Jeanne rubbed the thrashing gut with a soft smile.
"Look, he can't have been a good Christian, so you really shouldn't feel upset. I mean, you didn't when you were sending death threats to the Hussites. So I doubt you'll be losing sleep over Astolfo." Ritsuka snickered as he strolled into the room.

Alter and Astolfo thrashed in pain. Even Astolfo's lackadaisical attitude was gone thanks to the burning acid that ate away their flesh. The two screamed as the gastric juices filled the organ. The two were already submerged up to their chests. Their clothes were long gone, their hair followed quickly after, and their skin would not be long before it joined in the boiling pool of slurry. They beat helplessly against the flesh that surrounded them, but to their dismay, even their strongest punches bounced of the rippling flesh. Each attack burned pain into them, far more pain than whatever mild annoyance they might have delt to the saint who devoured them. A futile punch from Alter launched her backwards into the acid before she could even emerge from the searing liquid, she was greeted with horror as her arm melted to mush. The evil saint screamed in agony, but no one would save her. For a second time, she would be burned to death, but this time she was not even given the mercy of dying from the fumes. Her life and pain would go on until she sustained fatal wounds, blood loss, fumes, lost limbs none of that would kill her. only her head or heart being destroyed would put her out of her misery.
"DAMN YOU CHALDEA! DAMN YOU ALL!" the alter gargled in rage as she sunk under the waves of acid.
