The summoning room lit up again in front of Da Vinci, Mash and Gudako, the last Master of Chaldea had been informed of a new singularity that had manifested, and as always, she was trying to see if she could get any new Servants to join them before marching towards their new objective.
 
"S-Senpai please...we've been here for 2 hours now...I don't think you're going to be able to summon any new Servants...maybe we should-" Mash said before being cut by Gudako.
 
"Nonono, I'm sure there's some cutie out there waiting to be summoned, I've already used most of the resources we've gotten these months, so something has to show up, and I won't move from here until!-"
 
This time it was Gudako who was silenced, as the summoning room began to act strangely, the light in the summoning circle went out for a moment, before being replaced by a blood-red glow and a Servant card that the 3 girls had never seen before.
 
"Okay, that shouldn't happen, and that card is definitely not registered in the database."
 
Da Vinci tried to find an explanation or a reason for what happened, but stopped when the figure of the summoned Servant finally appeared, a small girl with blond hair and red eyes, with a draconic tail barely hidden behind her skimpy dress. However, what caught Da Vinci's attention the most was the classification assigned to her in the system once she was scanned. "BEAST"
 
"Okay, now I'm sure something is wrong here, this goes beyond even summoning a Grand." Da Vinci said with a tone of visible concern in her voice and her face.
 
"But, are you sure? She looks like Nero, also...haven't we already summoned beasts like Kama?...Gudako said crouching close to the girl, not realizing that she was looking at Nero Draco herself, the beast of Sodom.
 
"Senpai, I think we should listen to Da Vinci, something feels wrong here" Mash said leaning towards Gudako.
 
"Master, it's not wise to deal with that...thingm like that, Kama didn't even retain her status as a beast, this just isn't right, I'm going to call the security Servants to put her under observation while we find out what she is or wat she can do!". Da Vinci was visibly worried about this, the sensors indicated something very strange emanating from the little girl, Da Vinci felt that she was having a hard time even thinking just by being around her.
 
"You're exaggerating, if we were able to summon her it's because she's a Servant who responds to my orders, right? So it's okay, I have my command codes in case something happens, also look at her, she's so cute, she looks like Nero" Gudako didn't listen to reason, her joy at having a new and cute Servant blocked her common sense, as always, but this time she didn't realize how dangerous the situation was, while she looked into the bright red eyes of the girl who now gave her smiled. "Tell me, where you come fr--".
 
"Get naked", It was the only thing Draco said, looking Gudako in the eye, immediately, the redheaded girl lost the smile on her face, as she went into what seemed like a trance, she raised her hand and immediately used her command code "Yes, undress all". Before Mash and Da Vinci realized what had just happened, they were forced to start taking off their clothes, Da Vinci couldn't fight the order, but Mash tried her best to try to reach Gudako and wake her up, as she shed her armor, only to be met with a powerful blow from Draco's tail, throwing her violently against the wall.
 
Mash tried to get back up, without her armor, the blow had almost knocked her out, but things only got worse when she saw Gudako standing over her, completely naked, who proceeded to rip the shielder's clothes as if she were peeling a eggplant, the poor girl had no strength to fight and could only uselessly beg Gudako to stop. When she was finally completely naked, just like Gudako and now Da Vinci as well, Draco spoke again, "Eat."
 
Gudako picked Mash up carelessly, pulling her by the hair and licking her face before unceremoniously shoving her head into her mouth, there was no foreplay as Gudako liked when she was alone with Mash, she just started to gobble her up, it was an act of pure gluttony. Mash didn't even know how it was possible, but she was being eaten alive, her face full of terror and despair could be perfectly seen bulging out of Gudako's neck as she swallowed her.
 
Draco looked at Da Vinci, who was already getting over the effects of the command code when she finished undressing. She looked at Gudako again and spoke "Tell her to feed me." Gudako already had Mash up to her waist, so she simply raised her hand and mumbled the order while continuing to swallow. "Behhhmcmhhff hemmmf fooffhmm".
 
Draco watched with delight as Da vinci walked against her will, the petite girl turned around as she stripped out of her flimsy red dress, exposing her ass "Here", was the only thing she said as she spread her buttocks and exposed her anus, Da Vinci tried to resist more, but her body could not disobey her Master's infamous order as she raised one leg and thrust her bare foot into Draco's rear. The petite girl let out moans and guffaws as the caster sat on the ground for a foothold as she inserted her body into the tight ass, Draco could have easily corrupted her to do this, but Gudako forcing her was so much more sweet.
 
As if things weren't bad enough, Da Vinci could feel the searing heat of Draco's insides with every inch of her body entering that hellhole. She felt as if her body was inside a real oven with living flames while she was devoured by the girl barely half her size, was this something common to beasts? Or just something that Draco had chosen to make her victims suffer more?. It didn't matter, the pain and fear make that the only thing the genius inventor could focus on was screaming and begging her Master to wake up.
 
Draco didn't mind the yelling, but she wanted to have some more fun, so she spoke again, "Make her shut up.".
 
Immediately, Gudako, who was already sucking at Mash's ankles while licking her feet, used her last command code "Shummmf uhhmmpf."
 
Da Vinci's mouth now closed against her will, as the fire inside Draco's anus increase, the poor woman had been robbed of her only freedom, to scream, as her hips were sucked into Draco's hungry ass. Before long, only her head remained out of the girl's ass, Draco then jumped up and walked towards Gudako, who was now letting out a huge belch caused by Mash's frantic movements inside her belly, using her little strength to stretch Gudako's stomach with her hands, feet and face, looking for help.
 
"Let me help you with her," Draco said, making a Grail appear in her hand, filled with every corruption and hedonism imaginable, in the form of a viscous black liquid, spilling a little over Gudako's head as if christening her, Gudakoeven opened her mouth to let it enter inside her body, and soon after, a scream came from inside her belly, as the corruption took effect, turning her stomach into the same hellish oven as Draco's.
 
Mash screamed in pain and horror, testifying to the torture Da Vinci was going through inside Draco's ass without even being able to scream, only to fall silent soon after.
 
"Show me what you did with her" Draco said, to which Gudako nodded, turning around and dropping into a crouch before beginning to push, expelling what appeared to be Mash's body, perfectly sculpted into a statue that maintained even the smallest detail. A perfect statue made entirely of steaming shit, so hot it could almost burn to touch it, the hellish insides of Gudako's bowels hadn't taken anything from her, just turned her to waste, including her soul, all turned completely in the poop of the one who was once her best friend and love.
 
Da Vinci's eyes widened in horror. What had just happened to poor Mash was happening to her inside this beast's ass right now? Da Vinci couldn't see it, but indeed her body was beginning to turn brown inside Dracon's anus, a dark brown and smooth yet firm as her body, her soul, and her connection to the throne turned into nothing more than hot shit.
 
Draco turned around, showing her ass and Da Vinci's head to gudako, and spoke again, "Push her in." Gudako didn't hesitate, she placed her hand on the caster's head and push her deep, not caring about the horrible heat of Draco's ass, the corruption had made her tough enough to last a few seconds before it began to take effect, just enough time to make sure the brunette is well packed in that hot tight rectum.
 
Da Vinci couldn't scream, she couldn't even move against the abnormal strength of that anal muscles, while she was baked inside that anal hell, her body, even her tears, rapidly turning into poop.
 
Gudako took her hand out of Draco's ass, and no more than 4 seconds passed, before Davinci's head followed her again, along with the rest of her body, now turned into a poop-statue, a shade darker than Mash's, proof of the corruption and heat inside Nero Draco's ass, More perfect and detailed than any statue or painting that could be created, Da Vinci's greatest work was herself, and it was shit.
 
Draco looked at both masterpieces of filth, and used her tail to quickly rip off their heads, taking them in her hands, looking first at her own creation and gaping wide, sticking out her tongue and gulping down the Da Vinci scatue's head.
 
She tasted it and chewed a bit into her mouth before swallowing it completely "Mmmm, the taste of fear and pain, it's always exquisite." Then she looked at Mash's head, she had a sad expression with tears and a scream on her face, without a doubt her last moments were agonizing, Draco licked er lips and swallowed the anal chocolate, letting out a contented moan as she crushed her in her mouth and swallow it.
 
"Mmmm, despair and...sadness, a broken heart?, oh my, I think she took the way you two ended your relationship very badly." Draco chuckled looking at Gudako, who kept her blank expression amid both headless scatues of her lover and her friend.
 
"Well, you can eat the rest, I have to save room for all the delicacies I can find in this place, then I'll come back for you, oh, and be careful not to burn yourself, they are still hot" Draco said as she left the room without even bothering to get dressed again, behind her, Gudako immediately jumped on Da Vinci and Mash's scatues, ripping off their arms, legs and basically tearing them apart as she gobbled them up again, this time with a much more savage Gluttony.
 
There were only moans between each gulp, as the last Master of Chaldean, now a naked, wild and hungry animal, feasted with the steaming brow remains of her beloved servants, and the door behind her slowly closed.
