Command Seals were overhyped and yet underutilized in BB’s opinion. Most of it came from the Master’s unwillingness to use them in spite of the fact that they recovered every day… But this did leave her with a few options that she rather eagerly made use of now that the chance had vaguely shown up.
 
Sometimes, the Master needed a revival for one reason or another. A mission gone wrong or simply having gotten themselves eaten by one of their Servants! How embarrassing (lol)! Whatever the case, this left BB with just enough wiggle room to make some changes of her own and, ultimately, hijack a few of the Command Seals that they should have gained were it not for the fact that they already had three at the ready and couldn’t end up with four or an infinite number, unlike her.
 
Unlike the Master, she had plans for the Command Seals she had managed to obtain and the first one of those was driven by pure and absolute spite. Due to silly things like Class Advantage, Rulers were simply the most effective method to be used against her and she could understand that and knew what she had generally been getting herself into when she designed her own Class.
 
What she failed to have the foresight for however was the method of combat that Rulers tended to use. Why are so many of them physical fighters?! Were the requirements to become a Ruler Class the same as the ones to become Boxer Class!? Wasn’t that too cruel against her!? It was, wasn’t it?!
 
Naturally, she was upset and wanted some level of justice, or just to humiliate a Ruler or several to try and make herself feel better, which ultimately led her to her current situation as she walked through the Halls of Chaldea in order to meet a certain pair of Heroic Spirits. She already made certain preparations to get them in the same room together, messing around with some machinery and defense fields, all to make sure that they stayed where she needed them to be as well.
 
“It was about time!” Understandable as even she found the reaction to be, BB was only further annoyed when the first words she heard were Astraea complaining like a spoiled rich girl… Which her vessel pretty much was in the first place, meaning she even had the appearance for it.
 
Locked in a room for about half an hour now were the Ruler Class Pseudo-Servant Goddess Astraea and the Caster Class “Living” Servant Miyu Edelfelt, who happened to be the effectively adoptive sister of the goddess’s vessel, thus making the choice even better in BB’s eyes as she closed her eyes and raised her hand, stolen Command Seals glowing just below the glove on her hand.
 
“Hm? What are you doing?” Astraea crossed her arms below her chest in a stance that was almost intimidating and imposing, further driven by the fact the two of them clashed quite often due to the whole Class Advantage calculation.
 
“Where did you get those?” Miyu meanwhile asked the far more important question, not that BB would repeat her internal monologues out loud to explain it to the pair.
 
Instead, she opened her eyes and reached her hand forward, too far away to be stopped by Astraea in time even if she tried something. “Miyu, I command you to shove Astraea down into your cock.”
 
Funny thing about being a super powerful, super awesome AI and absolutely devilish Kouhai using Command Seals and just a bit of the Authorities of an Outer God. Reality itself tends to know when to bend to your whims and make sure that everything necessary was done and applied as necessary.
 
Though she only made the single command, two seals were consumed, along with an amount of BB’s magical energy, further locking Astraea in place for the Command to be fulfilled while a cock and a rather large pair of balls grew out of Miyu’s crotch, tearing through her magical girl outfit with an audible tear, much to the girl’s immediate embarrassment and Astraea being left gaping like a fish and blinking in surprise and confusion as she tried to fight the indirect command to be fed to Miyu’s newly grown cock.
 
“What is the meaning of this!?” Unfortunately, Astraea recovered far too quickly for BB’s liking and started making demands while Miyu was still blushing like the virgin she was, pushing down on her massive cock that simply refused to go down no matter how much force and how many small moans she made from just touching herself like that.
 
BB rolled her eyes at the combined display. She had to get the whole thing started, huh? “I think it’s pretty self-explanatory, but if you insist on having me explain it to you…” Walking forward, BB roughly grabbed the Goddess by the hair, pulling on it hard enough to get the dumb blonde stumbling backwards.
 
Miyu’s breath hitched as the Command continued to insist, creating an increasing need and hunger in her crotch, in her balls, making them seem emptier and needier to her than they actually were, leaving her almost frozen in place as she stayed sitting on the bed. It was only made worse for her as Astraea’s head was brought close to her cock, the goddess herself unable to really do much more than claw and struggle against BB’s hand. Of course, with the Command shared between them, she was only able to resist being fed to the cock to a certain extent, greatly draining the strength she should have been able to use against the MoonCancer.
 
“You… I’ll get you for this!”
 
“Oh, be sure that you do!” BB grinned. “I want you to remember every moment of this.”
 
As Miyu’s eyes grew unfocused, her legs opened with barely any actual will from the girl herself, her cock twitching eagerly and hungerly against and in front of the goddess’s face until they were brought close enough for the cock to start opening up. As if a gravitational force appeared between the two of them, the cock head even started catching some stray hairs from the Goddess’s head before her forehead was pressed up against the cockhead itself.
 
“Wait, wait, wait!” Astraea quickly went into the bargaining stage.
 
“D-Don’t do this!” Miyu shared the sentiment as well, even if she was still squirming and moaning with her hands holding her cock, squeezing it as if she wanted to prevent it from consuming the vessel but only sending herself further into pleasure as a result.
 
Naturally, BB did not head either request and just continued pushing, carefully positioning her fingers as she pushed and turned Astraea’s head, aiming it down into the urethral slit… And ultimately letting go as she pushed the head just past the eyes, taking away the Goddess’s ability to see, but not her ability to keep breathing.
 
“Don’t worry, you’ve got this!” BB encouraged. “Fight on!” She gave Miyu a cheering fist pump like some sort of cheesy cheerleader before taking a few steps back and letting the rest of the process come naturally.
 
The Command only intensified, Miyu’s ability to resist slowly being taken away along with Astraea’s; even as the Ruler tried to thrash and struggle, her body was moving forward and Miyu’s hips started rocking, pumping forward. Though both were clearly unwilling, Miyu biting her lower lip in attempted concentration and denial, she was quite clearly going through with this, to BB’s ceaseless entertainment.
 
With a loud moan that left her mouth gaping, Miyu put her hands on the back of Astraea’s head, pulling her forward even more, pushing the rest of her head, her cock expanding over the nose and engulfing even the mouth in the single, powerful, thrust and push.
 
“I’m sorry, I’m sorry, I’m sorry!” Miyu only proceeded to pull on Astraea's neck and shoulders as she pulled the girl inside herself in spite of the sheer difference in their size. There should have been no way for her to normally consume someone of Astraea’s size, willingness aside, but she proceeded anyway.
 
From certain angles, Miyu even looked like she was face-fucking someone or just using an onahole with considerably violent movements. Astraea’s hands meanwhile found Miyu’s thighs, sinking her fingers into them to try and stop the process, to try and stabilize herself, with no success. If anything, it seemed to make the Caster even more excited!
 
“You’re doing great sweetie, just keep going.” BB continued to encourage, walking up behind the Goddess and starting to pull on her clothes, slowly tearing them off of the body to leave her naked and easy to consume, with certain exceptions. The fact that she wasn’t wearing a bra in the first place was not exactly BB’s fault, was it? She left her with her panties though, at the very least.
 
“Please…!” Miyu begged while Astraea gave her own muffled screams that simply made Miyu shudder due to the sensitivity of her gluttonous cock.
 
“Oh please, you have hearts in your eyes.” BB pointed out, just barely being metaphorical about it at that. “You’re clearly enjoying this.” She couldn’t force everything about this situation, after all, and all of the pleasure the usually stoic girl was feeling was entirely her own, for better or for worse.
 
Miyu was unable to reply to that fact, her hands still squeezing down on her “friend’s” arms and pulling her in, her cock expanding to immense sizes to engulf the shoulders, squared forward to reduce the amount of space they took up as much as possible, squeezing the Goddess’s respective chest forward even if Miyu was not quite in a position to see it.
 
No longer able to keep her hands on Miyu’s body due to her arms being forced to her sides and in front of her, Astraea just started thrashing her legs around, unintentionally kicking and nearly launching herself even deeper inside. The cock was considerably wet and slick, making her passage all the easier and uncomfortable for the parts of her body already inside.
 
Every squirm, every movement, that she made only pushed her further inside. She, the virgin goddess of justice, innocence, purity and precision, was absolutely and undeniably losing to a cock, which only made the situation worse for her! She could almost feel tears forming in the corners of her eyes, but it could have simply been sweat, or even precum.
 
Just as she was thinking that as well, Miyu’s head shot backwards, her body shuddering the moment her cock reached the goddess’s breasts, barely starting to work its way up the curve of the breasts before Miyu was pushed over her edge and started orgasming around the goddess. While some might have even been able to cum in spite of such a presence in their cock, Miyu was not one of them.
 
Shot after shot of cum burst up from her balls, crashing against Astraea’s face and going into her mouth and even her nose, whatever hole it could find to force itself into or simply staying in the general area of her shoulders if it couldn’t enter anything, making the goddess feel even more dirty and defiled then before.
 
Miyu’s breathing got even heavier as she recovered, her hips still moving forward, her cock still consuming the Ruler as she fucked her way up the actual breasts, the tit fat being compressed softly into the cock, just barely bulging the phallus even further. In a matter of seconds, it even crossed over her hardened nipples, making both of them shudder.
 
BB decided to make her presence known again as she reached around and over, reaching her arm over the sheer size of the cock, wrapping it in a one armed hug that placed her hand in just the right way for her to trace the outline of the breasts, poking them and the cock flesh, putting pressure right against the nipples and pressing them repeatedly and mockingly even if her finger was only just barely able to push into the sheer hardness of Miyu’s erect cock.
 
Adding even further insults, Astraea’s head started to be pushed into Miyu’s balls, dipped right into the recovering and growing pool of her cum. It smelled horrendous, obviously smelling like depravity and quickly filled all of her available senses as it threatened to drown her and, externally, her face started bulging and outlining against Miyu’s nuts.
 
The goddess’s stomach was flat, featureless, lacking anything to make it interesting and making it a perfect waist in every way but the length which continued to make Miyu moan as she fucked her way along the expanse of it, moaning all the way through and losing herself in the sheer pleasure as more and more of her hesitation vanished along with her cock snack’s body.
 
Miyu knew she was past the point of no return, yet her mouth kept moving in attempted denial and bargaining to get BB to stop, to cancel the command… Not that the MoonCancer listened, instead getting visibly annoyed at Miyu’s continued overall lack of cooperation. There wasn’t much to be done about it right now though, so she just gave Astraea’s ass a hard-enough slap that it sent her another inch deeper inside and even managed to leave a, temporary, red handprint on her ass as BB made some distance again and watched the rest of it from a short distance.
 
With most of the weight now being on Miyu’s side, either in her cock or in her balls, the Ruler’s outline was still rather detailed even if some of the curves were hidden by cum, the cock was able to start lifting the rest of the girl up into the air. By the time Miyu reached the actual ass as well, it was being lifted up into the air to let it slide in easier, Astraea’s feet slowly being forced to stand on her toes to retain contact with the ground.
 
It did not last long however, the ass sliding in and being consumed just like the rest of her, leaving only the legs to be consumed. In their final moments, Astraea’s panties were soaked for one reason or another, which was still unrelated to Miyu’s cum possibly staining it. Of course, it couldn’t be fully be dismissed that being bathed, being drowned, in cum was not exciting the goddess in ways she would rather deny, as far as BB was concerned.
 
Whatever the case, the supposedly virgin goddess’s legs weren’t able to stay bent and floor-bound forever, instead rather rigidly pointing out of the cock with a surprising display of leg muscle strength.
 
At this point, Miyu did end up rushing to just get it over with, both hands on her cock as she stroked frantically, every stroke pulling the last of her food deeper inside her, working her way past the thighs, knees and shins until, ultimately, all that was left were her curling toes just past the cock head, Miyu shuddering again in an involuntary orgasm right at the finish line.
 
Bb decided to help finish it off anyway, pushing the soles of the feet with a ring and middle finger before starting to stroke the cock herself until the full length of the legs were gone, the Ruler’s whole body being held and imprisoned inside Miyu’s balls, the girl herself still struggling to catch her breath as Astraea was almost visibly keeping her mouth shut.
 
“Congratulations! Was she delicious?” The only response BB got were some shuddering breaths from Miyu, almost on the crux of crying. With the command fulfilled, both the Caster and the Ruler were regaining their full capabilities to move and think properly, though both were clearly unable to move right now for varied reasons.
 
“How… How do I get her out…?” Miyu asked.
 
“Out? Well, when you’ve churned her…”
 
“Churned?!” Though there were no physical signs, BB just knew that both Miyu and Astraea started trying to go into Spirit Form to escape the situation… But nothing would happen.
 
“It’s not that easy to get out of this, you know?” BB teased, flicking Miyu’s cock. “The only way she’s getting out of here is as cum… I thought you understood that from the start?”
 
“N-No! I— Ah!—I didn’t!” Unable to escape the easy way, Astraea started visibly thrashing and struggling, trying to get out and away the physical way no matter the cost to Miyu. Each movement was clearly outlined against the balls as well, making for quite the entertaining show as Miyu squirmed in pain and pleasure, unable to escape as her balls simply hung from the side of the bed, oversized and easily twice her size.
 
“…are you sure you’re smart? Geez, neither of you can understand obvious things, can you?!” BB playfully pouted, putting her hands on Miyu’s balls. “Well, I’ll be merciful this time and help you out. I know she can be painful, so I’ll help you get rid of her.”
 
“R-Rid?” Miyu repeated with a bit of fear before BB started pushing her hands against the balls, rubbing and massaging pretty deeply into them… And causing a further effect on the gift she gave to the girl
 
Miyu’s cock started twitching again, expelling cum as if it was making additional room, finally staining the bed and her legs with nothing left to obscure its path. Her hands went around BB’s wrists, trying to stop her, but failing to actually accomplish anything while the balls simply grew tighter and tighter, BB’s face a mocking smirk as she further prompted the balls to speed up the process with some time related hax.
 
At a visible rate, Miyu’s balls began to shrink on the outside while on the inside, Astraea started squirming even harder, her whole body starting to break down, starting to get converted into cum in a process that was neither gory nor actually painful. She simply started losing coherency to her body, her fingers, hair, breasts, extremities in general starting to turn into pure, thick cum, falling off of her body.
 
Even when she should have died by normal logic, she was still aware of it all as it happened, leaving her as nothing but a bald head and feeling even that vanish and be broken down until she was left as nothing but a barely sentient viscous liquid, as raw cum inside Miyu’s balls.
 
She was shrunk down considerably in a matter of seconds, barely taking a whole minute until Miyu’s balls, put together, were roughly as large as her own head instead of the previously massive size, though they were still oversized even compared to her cock.
 
“There we are~ Now, while normally she would have gone to the Throne of Heroes, she’s sorts of stuck in there for the time being.” BB explained. “So, don’t keep her in there for too long! Find a nice wall or a toilet and she’ll eventually return after a while… Or even shoot her into someone! That could be fun, right? …Or ask Merlin for a condom, I guess.”
 
“She-She’s what?”
 
“Geez, Miyu…” BB pouted all over again. “Did your brain turn to cum as well? I don’t feel like repeating myself! Whatever, just… Good luck, I guess. With your cock still throbbing like this, I don’t think it will be long before this gorilla Ruler is staining something or another.”
 
With a last chuckle at a joke that was only funny to herself, BB just dusted herself off, the stray cum that tried to cling to her easily being flung off as well before she gave Miyu, who was still processing, a farewell wave and left the room without any further elaboration.
