No one knew how it had happened, but somehow, during the last summoning rite in Chaldea, instead of some pretty girl or boy, two bicorns had been summoned. The beasts were almost exactly identical to any other bicorn known so far, at least from afar, from up close, several unique details could be appreciated, such as their colors, snow white and jet black, as well as their huge juicy asses, capable of leave in shame many of the chaldea girls, not to mention their huge cocks, massive even for a horse or even bigger animals.
 
 
Ritsuka blinked in confusion and looked over at Da Vinci and at Mash. "So... how in the fuck did that happen?" Ritsuka wasn't sure if she should be angry or not. These bicorn looked insanely powerful and hopefully they'd obey her, but she'd hoped for a hot babe or a sexy guy she could... do things with.
 
 
The white bicorn licked his equine companion in the face, it was obvious to the girls in the room that they were a couple, even given the fact that they were both studs, maybe it was a magical or demonic creature thing or whatever they are, ritsuka thought, before the white bicorn approached her and turned around, showing off his huge juicy ass, maybe he wasn't one of the girls ritsuka used to enjoy...but he was sexy, that's for sure No doubt
 
 
Ritsuka blushed and halfheartedly looked away while glancing to the side. She figured she was into humans... or well humanoids since most of her lovers weren't fully human, or in a few cases weren't human at all. "Hmm, we somehow managed to summon two. Could they be like the Dioscuri, two spirits in one?"
 
Da Vinci shrugged. "I'm as confused as you are Fujimaru." Da Vinci blushed slightly and moved around the one bicorn looking him over. "He's quite the... specimen."
 
 
The bicornis seemed submissive, and much more direct than most of the…servants Ritsuka used to summon, even shuten douji had gone first for drinks before moving on to sex, but these handsome studs were there, showing off their asses, stretching their buttocks to show their big juicy donuts to the girls in front of them, Ritsuka thought there was a limit to how kinky she could be, and that she reached that limit after ordering Da Vinic to modify everyone in Chaldea to have massive cocks, which now they couldn't even hide while looking at those huge equine asses and balls
 
 
Ritsuka blushed and reached between her legs to stroke her massive meat. "Fuck it, I don't know why, but I want them to take me. Well one of them." Ritsuka stripped down and got on all fours under one of the bicorn. "Fuck me still big boy!" Da Vinci was doing something similar for the other while Mash could only watch in a stunned stupor
 
 
The bicorns looked at each other for a moment, it was hard to tell, but on their faces there seemed to be something resembling a....smile? There wasn't much time to analyze it as they positioned themselves over the naked bodies of ritsuka and da vinci, They proceeded to insert their massive cocks into the asses of the girls with equally massive cocks, in a spectacle that no one outside of Chaldea could ever imagine.
 
 
Mash's lone visible eye bugged out as she watched her lover and... mother figure get fucked by the two giant stallions. Ritsuka's eyes nearly rolled back in her head. "Holy fuck! Mash... mm you've got to try this!"
 
 
Meanwhile, Mashu watched from close, her huge cock throbbing inside her clothes, watching her beloved master get fucked by those sexy horses, and at the same time, looking at those huge equine asses, as if she was being invited to do something she had never would consider before
 
"I-I-I----i could.....his ass....." say mashu while aproach and spread the buttchecks of the black bicorn "m-my cock....his ass....."
 
 
Ritsuka giggled and moaned loudly and lewdly as the bicorn above her railed her like some cheap slut. "Heh, you know you could just wait your turn my beloved Mash!" Ritsuka had been overjoyed to learn Mash was quite the freak in bed.
 
 
Mash could hardly resist any longer, the sounds of Risuka and Da Vinci being fucked by the bicorns was too much, the eggplant girl took off her clothes until she was naked, her massive cock throbbing as she aimed directly at the black bicorn's huge ass, before thrusting all her length in one push into the warm depths of that equine anus
 
Mashu moaned as she fucked the demon horse, unable to contain herself, before quickly switching beasts and going for the white one, switching her cock from one bicorn to another.
 
 
"Mm, come on big boy fill me up!" Ritsuka moaned. She clenched her ass trying to milk the giant horse for all the cum stored in his massive balls.
 
Da Vinci wanted to paint this. She could always ask her younger self to do it. "Oh fuck that would be so hot! I'd have to put it on the wall of my workshop!"
 
 
The mix of Ritsuka and Da Vinci's tight asses, along with Mashu's huge cock fucking their juicy equine anus, was more than enough to make the bicorns spill the thick, hot contents of their balls into both girls' asses, filling them up like balloons, while mashu did much the same with the studs, and ritsuka and da vinci created a massive puddle of cum on the ground below them
 
The bicorns looked at each other, and kissed while filling the girls with cum and getting filled too. "Heh.....gay bicorns, well, is not the most weird thing that i see....maeby..." say ritsuka
 
 
Da Vinci panted softly. "Hmm, honestly this might be the weirdest thing we've had happen to us." Da Vinci thought over the massive list of things they'd seen or done. Ritsuka had fucked every or just about every servant here. Ozzy was one of the few who always rejected her. He truly was devoted to his late wife.
The bicorn in front of Mash looked at his partner and snorted before lifted his hips up then slamming his ass down right on top of Mash's head.
 
 
Ritsuka could hardly react to what happened, suddenly, the bicorn they were fucking, had just sat on her girlfriend's face, or rather, the correct word would be that he had just swallowed her girlfriend's head with his ass. Ritsuka didn't know what to do, she had mixed feelings about what she was seeing, she had to help mashu right?, but he didn't want to hurt her new…servants?, maybe it was all another lewd horse game?, all that went through her head, but her only response was .... a throbbing erection, before the white bicorn did exactly the same with her
 
 
"Oh wow...this is certainly...interesting" da vinci replied, she could only be amazed at how things were developing, she knew it was a priority to save ritsuka and mashu but... when would she have the opportunity to witness something like this again? "I'm sorry Master...but I can't pass up the opportunity to document something like this, if only I had a-" The door burst open. "camera!?" Da vinci chan say, going inside of the room at the side of her older self
 
 
The bicorn slowly lowered itself backwards enjoying the feeling of Mash being stuffed into his bowels. Once he reached her waist he paused then relaxed his anus and moved his hips up. He repeated the process several more times taking a little bit more of Mash in with each drop of his hips.
 
Da Vinci was watching with fascination when she felt something hot and sticky around her ass cheeks. Looking back caused her to pale. The bicorn that had fucked her silly had just swallowed her ass... with his monstrously huge cock.
 
 
"Wow....okay...this is certainly something worth documenting....but you know...I won't be able to do it if you swallow me....so if only you could...let me go. ..please?" Da Vinci asked with an almost playful tone, but she only got her ass swallowed a little more by the bicorn's cock as an answer. "Emmm...young me....could you give me a han--" The inventor fell silent as she saw her younger self, being swallowed by the other bicorn's cock, the beast already swallowed her up to the waist, head first, the shape of her fear-filled face fully visible through the stretched out cock
 
 
Meanwhile, Ritsuka and Mashu weren't having so much fun anymore, being used as anal dildos by a couple of studs was one thing, but if that wasn't enough, their anuses were incredibly hot, and the melted shit inside them was too. , feeling like lava as it spilled and trickled over their bodies with each bounce of the bicorns.
 
 
The younger Da Vinci was being quickly slurped up thanks to her smaller size while the older Da Vinci was put in an uncomfortable position thanks to her legs being pressed against her chest. The insides of the bicorn's dicks were pretty hot but not quite as bad as their asses.
 
Ritsuka and Mash both shouted for help as they were completely swallowed by the giant horse monster's asses. Both bicorn let out a fart as they girls were swallowed by the bowels of the demonic beasts.
 
 
The bicorns looked at each other, and again began to kiss, as their cocks began to suck what was left of da vinci and da vinci chan, the latter with her face and feet being sucked into an incredibly uncomfortable and painful position inside the cock of the black bicorn
 
Both studs' asses were working fast, Mash and Ritsuka weren't even halfway to their stomachs when they started turning into shit.
 
Bicornis loved to eat cute girls with their asses and cocks, but their mouths were reserved only for the delicious anal chocolate produced by their equine lover.
 
 
Both Mash and Ritsuka started to sweat and squirm as they could feel themselves being transformed. Even their souls wouldn't escape. For them this would be true death, even reincarnation wold be off the table. For the Da Vinci there would be no returning to the throne once they were reduced to cum.
 
 
The white bicorn crouched down, sticking out his long tongue, and began to lick his lover's massive cock, feeling the bulges that da Vinci's body made.
 
His tongue was strong enough to squeeze the black stud's cock, giving him pleasure, but at the same time making da Vinci suffer even more as she was crushed inside.
 
 
The smaller Da Vinci screamed in both pain and fear in the sack of the giant demon horse as she was turned into cum. On the ass cheeks of the horses appeared the faces of Mash and Ritsuka, forever separated both in body and soul. The tattoos would fade once they souls forgot their previous identities and accepted their place as horse butt.
 
 
The horses felt a wave of pleasure when they felt the mana of ritsuka and mash inside them, they began to kiss again, but this time, the excitement caused them both to produce electricity, a natural ability of the bicorns, what was left of Mash and Ritsuka could feel the pain of being electrocuted, even if they was just ass-tattoos, and it was even worse for both da vinci, inside the studs' balls
 
 
Both Caster and Rider screamed as they were electrocuted and melt into spunk. Da Vinci Lily was barely hanging on as Ritsuka command spells appeared on the ass of the bicorn that had devoured her. It was pretty much the official master of Chaldea now, not that it could issue orders.
 
 
The white bicorn walked around his lover, towards his huge and beautiful ass, sticking his snout between the fat buttocks, and starting to lick the huge glazed donut, the souls of ritsuka and mashu were now in the butts of the bicorns, but their bodies, now converted to anal mud, were still inside the stallions
 
 
The black furred stallion started to relax as he focused on pushing the shit statue of the girl in his bowels out for his lower to devour. The Da Vinci in his nuts had been completely melted with a tattoo of her horrified face imprinted on the side of his sack a grim reminder of her final fate.
 
 
The white bicorn licked and sucked his lover's anus, sticking his tongue deep and playfully biting the anal donut. Feeling the shit inside his lover in the shape of a cute girl, with his long tongue
 
 
The black bicorn grunted as he pushed out the scatue that had been formed from Ritsuka. The expression of her tattoo changed to disgust. She could feel her body being forced out of the horses ass. "Oh fuck that's kind of hot but also super weird!"
 
 
The white bicorn let Ritsuka's scatue peek out of his lover ass before taking a big bite and starting to chew, bit by bit, and somehow Mash and Ritsuka were able to watch the whole show
 
 
Though both women could sort of speak, pretty much in their own minds they couldn't hear each other. Tears would be rolling down Mash's cheeks as she watched Ritsuka's body being ruthlessly devoured like a tasty treat, which it was. "Senpai... I'm so sorry."
 
 
The white bicorn greedily ate everything his equine lover's ass had to offer, chewing with his mouth open, letting Mash and Ritsuka watch as he tore apart and swallowed what used to be the body of Chaldea's last Master, gobbling it up until the last piece, and lovingly licking the black bicorn's shit-covered donut
 
 
 
Once his lover finished licking his ass the black furred bicorn moved around behind the white furred one and nuzzled his face against his lover's rump. He sent a small jolt of electricity through the other demonic horse knowing it wouldn't hurt him but would hurt Mash and Da Vinci.
 
 
The white bicorn neighs with pleasure, producing electricity himself, damaging the girls inside him, while expelling the remains of mash in the snout of his quinine lover, little by little, letting him taste and chew
 
 
The black bicorn happily devours the shit statue of the girl pausing to kiss the tattoo of her that remains on his lover's ass cheek. Little by little all that was left of the shielder was devoured by the vile horse.
 
 
The white stallion turned as his lover finally swallowed the last bit of what once was the shielder. The bicorn stood in front of his dark-skinned lover and gave him a messy kiss, playing with his tongue while letting out a huge fart, which was nothing but mash's soul evaporating.
 
 
The black stallion nuzzled against his lover then motioned towards the door. He could sense plenty of delicious energy rich ladies out and about through Chaldea.
