Nerofest - a wonderous event hosted by none other than the adorable and magnanimous Nero Claudius. As a Master of Chaldea, this presents a great opportunity to test my mettle against a number of great and rewarding challenges.
However, more imporantly, it offers another chance to summon Nero Bride; Nero Claudius' alternate-self, bride counterpart.
 
It has been many months since successfully summoning her the first time during Valentine's, and she's stuck to me like glue since then.
We've been through many battles and hardships, as well as plenty of good times, and *even better* times; she makes sure that it's abundantly clear that I'm HER husband.
So it's only fitting as a gift to her, to attempt to summon more of her, in order to strengthen my glorious emperor-wife.
 
I head to the Chaldea summoning platform with my giant bag of saint quartz to begin the arduous task of summoning "food" for Nero.
 
The stage is set, the catalysts are in place. The energy flows through me as I begin to cast the summoning...!
 
Nero: "Master! Dear! What are you doing? We should be in my arena, battling for glorious victory in front of countless cheering fans! Why do you keep yourself cooped up in this summoning room so?"
 
Before my concentration is shattered by the arrival of my dearest.
 
Master: "The magical energies have aligned, the time is ripe! I'm attempting to summon more of YOU, of course!"
Nero: "What?! Surely you jest! Is one of me not enough for you? Am I, in all my majesty, not enough?!"
Master: "No, no! Of course you're enough! The additional you's would be for your benefit. When they appear, I would have you consume them for nourishment to strengthen you!"
Nero: "I see. However, Master, if I were to eat an entire me, would I not become fat and unfit for battle?"
Master: "Heh, as far as battle is concerned, I don't think your weight would be an issue; just look at Julius Caesar. Plus, you'd still be adorable with some extra chub, maybe even more so."
 
She blushes, speechless for a moment.
 
Nero: Y-yes, of course! As if I would let a little weight slow me down! Umu, it is indeed as you say. My master is ever a genius to rival my own!"
 
She watches from behind as I begin to summon again. This time I start with a small stack of summoning tickets.
Master: "Welp, may as well start with these."
 
But to my amazement, as well as Nero's, it only takes the energy within this small stack of tickets to call forth an additional Bride!
 
Second Nero: "Umu... I am back with a new dress! Call me Bride Saber, or Nero Bride! Though, strangely, it seems as though we are already quite.. acquainted.
I feel as though I've known you for many months, even though we've just met!"
 
She says this, though I know it's a phenomenon brought about by the servant bond system, where new copies of previously existing servants are granted copied bond status and memories.
About this time, my original Bride walks up to the platform from behind me, and the new Nero's countenance visibly sours.
 
Nero: "I see that my first strengthening meal has arrived, and quickly at that! You really do seem to have an affinity for me. Umu! Well done, Master! I will see to it that you are rewarded for your efforts... later on tonight."
Second Nero: "Hmm.. that would explain why you seem so familiar to me, Master, because I see we have already been married for quite some time!
And look at you, 'First Me'. Level one-hundred, maxed skills; you certainly are the fat, pampered emperor, aren't you?" The new Nero says, somewhat mocking her other self.
Nero: "Yes, and soon to be even fatter after I consume you for your power! You devilish, teasing 'Me'."
 
The two Neros continue to poke at each other for some time, completely oblivious to me. All the while I'm furiously summoning, watching my quartz dwindle by the second, until finally-
 
Third Nero: "Umu... I am back with a new... wait what? What is going on here?! Why are there two more of me here?!"
Nero: "Wow, Master, you've really outdone yourself.. You must really want to fatten me up! But I accept it! I would gladly consume any number of myselves if you will it! Be it for strength, pleasure or otherwise!"
Third Nero: "Consume? Yes, as it seems that *me* over there is much more powerful than myself or the other *me*. Is that all we have been summoned for, Master?!"
Master: "Yes, it is regretful to send you Neros on your way so soon, and in such an undignified way, but this Nero is *my* Nero. She's been with me through thick and thin, and it's only right for me to wish to strengthen her. You two understand, right?"
Second Nero: "A moment please, if you would, Master. I wish to speak with the Third."
 
The two walk to the other side of the room and begin to converse. Occasionally, the second will glance over at us, and point or make some ridiculous gesture. Finally they finish and both look over with devilish grins.
 
Master: "Did you two work things out?"
Second Nero: "Yes! In fact, we've decided that we would like one final request before meeting our fates."
Master: "Of course, that sounds reasonable. My Dear, what do you think?"
Nero: "No problem at all! What kind of gracious emperor and wife would I be if I didn't show mercy to myself?"
Third Nero: "Good! Then our request is simple-"
Second and Third: "We wish to consummate our marriage with Master!"
 
My jaw drops for a moment before I fully realize what they just said. Though it seems my Bride understood full well.
 
Nero: "Absolutely not! Master is MY husband and MINE alone! Only I may be allowed to taste his mana."
Second Nero: "But we are you! Are you so selfish that you wouldn't share with yourself?"
Third Nero: "What happened to the 'gracious emperor and wife'? Surely if we're all Nero, then he's all of our husbands!"
Nero: "But I.. you.. me..? Arg!"
Master: "Maybe they do have a point, dear."
Nero: "Master?!"
Master: "It's only fair. I brought them here, basically just to appear and die to become fat on your chest. I am willing to grant their request."
Nero: "Oh, of course YOU are! I see how it is, fatten me up and move on to another woman!"
Master: "But they're you, Nero."
Nero: "Fine! But on my own condition, you may not cum! Not even once! I forbid you from wasting MY mana on these twin concubines! Also, I shall remain in the room in case things get out of hand."
 
From there, we head back to my room. The Nero twins lead, giggling and sneering as if they won some great victory, as I follow and my Bride follows behind.
A few moments pass, and the two Neros have stripped and are ready. Bride sits upon an ornate, cushioned chair, begrudgingly waiting for this formality to end.
 
Nero: "Uhg.. you may begin."
Second Nero: "Good, then let us! I have a powerful need, so let us cut to the good part! I will take Master's dick, because this was my idea. You may have his face."
Third Nero: "Fine, fine. This is all payback to the 'old maid' anyway."
Nero: "Old maid?! The nerve! Master, this is clearly malicious intercourse!"
Master: "B-but I'm responsible for this negativity. Once they're satisfied and tired, they won't mind as much when you finish them of- *muffle*!"
 
At that point, the Third Nero sits down on my face, cutting off my vision and speech, as the Second begins to expertly ride my dick.
 
Second Nero: "Oh, yes, just as the bond system recalls... Master's dick is large and exquisite!"
Third Nero: "Umu! Master knows just where to tongue to hit allll my spots."
Nero: "Umu. I will not deny; Master has become quite skilled. Enjoy it while you can, for next time you have sex with Master it will be as a part of me!"
 
The two continue on, riding and humping, moaning and squeeling, even leaning in to grope and make out with each other.
 
Nero: "Oh my.. making out with myself might be excellent. Perhaps I should try that before eating both of them.. No, no. They both certainly must go."
 
Finally they both cum together, moaning in stereo and drenching my face in Nero.
 
Second Nero: "Hah.. hah... how was that, Master?"
Third Nero: "Good, right? hah.. Better than, hah.. that other woman! Did he cum yet?"
Second Nero: "No, I'm still dry; I do not feel his mana. He's truly a resilient one."
 
She says that, but her riding skill isn't to be underestimated. It's taking every ounce of my will to prevent exploding in to her. Despite this circumstance, my Bride made me promise, and I won't betray her again.
 
Third Nero: "Then we must turn up the heat! Tap in to the full extent of your riding skill and make him burst!"
 
About this time, I hear a very displeased grunt from across the room.
 
Nero: "That's quite enough! Grr..! I will not lose to myself!"
 
I hear loud footsteps as my original Bride seems to be running over from her seat, before suddenly my vision is restored by the removal of the third Nero's rear from my face.
I look to my right to see my first Nero, who is obviously much stronger, holding the nude, third Nero by her arms in the air.
 
Third Nero: "Unhand me, harlot! I am not yet finished with Master!"
Nero: "How unfortunate... but Master's mana is for ME, and THIS me, alone! It's time I put these unruly copies in their place!"
 
With that, Nero opens her mouth up as wide as possible before engulfing the head and neck of the third Nero in one gulp. She begins to struggle, but the ninety-nine level power difference means she can't even make my Bride flinch.
As my Nero continues to swallow her meal, quickly the lock and chain around her neck breaks off and falls to the ground, followed shortly by her large, plump breasts popping out of her top as her chest stretches around her meal.
She's making a very serious, yet somewhat pleased face, all the while consuming the other Nero. She moans occasionally, while slurping loudly, seeming to enjoy her own flavor.
The Third Nero has been swallowed down to her waist by this point, her plump butt now sticking up in the air. My Bride's belly has begun to stretch, steadily growing with each swallow, and the large frontal zipper on her outfit has begun to give way.
Finally making it past her butt, Nero quickly slurps up the Third Nero's legs, her belly swelling greatly as the zipper simultaneously unzips as if to purposely unleash its girth, culminating with the zipper opening fully as she swallows her meal's toes.
 
I expected seeing her devour herself whole would be quite the spectacle, but never did I imagine it would be so entrancing. The stretching of her body, the sweat glistening on the skin of her taut belly as it swells to take in her large meal.
I nearly cum again while watching her, before I realize the second Nero is still riding me, trying her hardest to take my mana from my Bride.
 
Second Nero: "Cum already! Cum damn you!"
 
Despite her being level one, as a servant she's still vastly stronger than me, a mortal master, so I'm unable to do anything to stop her. I grunt and gird myself, continuing to resist her efforts as I wait for my Bride to save me from my self-inflicted torment.
Finally, Nero has recovered and re-balanced herself after her meal, and she waddles over to the remaining Second Nero.
 
Nero: "I'll not have you stealing MY husband anymore! Join your fiendish twin in my stomach!"
 
She says before grabbing the second Nero, just like the other one, pulling her up over her belly, and in to her mouth.
She seems to be more proficient at eating whole people now that she has some practice, making shorter work of the second Nero; licking slurping and teasing her all the way down.
Nero's already large belly stretches greatly, doubling in size as the second Nero settles in to her fleshy tomb with her twin.
 
Nero: "*Belch* Oh, pardon me! There, now you two are where you belong!"
 
She slaps her belly as if to prove a point, eliciting some movement and muffled complaints from her meals.
 
Nero: "Hah, you two are nothing but the most recent Imperial feast now! Umu, I'm more delicious than I expected!"
Master: "You look.. so incredible, Nero."
Nero: "Umu! Praise me more, Mas- wait. No, no, do not try to distract me! This entire ordeal has upset me greatly! I feel like a bloated whale, which isn't so bad, but I'm stuffed with these two troublemakers that you insisted you owed some debt to for sacrificing them!"
Master: "B-but they were you, Nero!"
Nero: "Nay! Just because they are Nero, does not mean they are me! If you summoned them to be my food, then they shall be my food and nothing more!"
Master: "I.. I'm sorry. I understand now, dear.
Nero: "Good! Now for your punishment!"
Master: "P-punishment?"
Nero: "Yes! Commend yourself for resisting cuming in that harlot for so long, or it would be more severe. I will be having sex with you, but you must bear the weight of my swollen stomach on top of you during it!"
Master: "Oh.. is that it...?
Nero: "What did you say?"
Master: "I shall bear it gladly!"
Nero: "Umu! That is what I thought!"
 
However, just as Nero is about to mount up, a shocking surprise walks through the door.
 
Fourth Nero: "Oh, Master! There you are! I've been looking all over, it seems somehow you summoned two of me without knowing it."
 
She pats her belly for emphasis.
 
Fourth Nero: "I materialized first, so when she appeared, I took it upon myself to consume her for her power! I hope you don't mind... wait.. what's going on here? What's with that even fatter 'Me' standing over there?"
Nero: "Master.. what's going on?"
Master: "I'm not sure.. I believe I accidentally left my remaining quartz on the platform when we left, but there must have been some residual summoning energy remaining in the system."
Nero: "*gulp* Well, Master, after what we just went through, I think we need to deal with this quickly before it gets out of hand again."
Master: "Agreed. By my command spell, I order you, Fourth Nero, feed yourself to the even fatter Nero!"
Fourth Nero: "What?! I.. to that?"
 
And that's all she can get out before the command takes over, and she strips before walking up to Bride. Bride bends over, letting her large belly touch the ground, and opens her mouth wide enough for the Fourth Nero to dive in, arms first.
Nero quickly gulps her down past her chest to her own swollen middle, before standing up straight, lifting up the Fourth Nero, to enlist gravity to aid her in attempting to swallow the very large double meal.
She gets stuck at the belly for a while, vigorously yet carefully sucking on the orb of flesh. Inch by inch she slowly swallows it down, until enough of it finally passes her throat.
It plummets in to her stomach, quickly taking her legs down with her faster than Nero can slurp them up, causing her stomach to stretch almost explosively, doubling in size from her previous meals.
 
Nero: "*Belch* Umu... what a gut, and I thought I felt full before... ooh."
 
She rubs her now-massive belly all over, no doubt trying to soothe the bloated discomfort she must be experiencing.
 
Master: "Whew; crisis averted."
Nero: "Well, Master, how do I look? More womanly? Your blushing bride with huge, ripened stomach as if full to bursting with your children?"
Master: "Uh... I.. *gulp*"
Nero: "Heh, it has been some time since the 'twins' were riding you... your 'Little Master' betrays you."
Master: "...."
Nero: "Hahahaha! Good, good. Oh, I'm feeling so good, I'll even forgive your 'even fatter' comment earlier. However, there is still the matter of your earlier punishment."
 
She waddles over to my bed where I have remained since the feast began. As she gets closer, it's even more surprising to see, up close, how huge she has become.
 
Nero: "Prepare yourself, Master, and enjoy the next several hours from beneath my gut! I command it!"
 
 
[The next morning]
 
 
I wake up in my room, on the bed in the same place I recall finally passing out underneath the massive weight of my Bride's belly. It was nearly unbearable, yet also incredibly soft and sensual.
However, it seems that she's no-longer in the room. She must have gotten up already and not wanted to wake me early after such a night.
I get up and quickly realize I am still without my pants. I quickly fix this problem before anyone else decides to come in the room, before heading off in search of Nero.
Soon after leaving my room, I run in to Mash.
 
Master: "Morning Mash. Have you seen Nero Bride anywhere today?"
 
At the mention of her name alone, Mash begins to blush intensely. Strange.
 
Mash: "Oh.. Yes, Senpai, I've definitely seen her. She said she was going to the simulator to test out her new noble phantasm strength..."
Master: "Oh? Great! Thanks Mash."
 
I dash off in that direction too quickly for her to respond, though it seemed as though she continued to stand there, blushing.
I arrive at the simulator, and see Nero just as she finishes a strength test trial. I walk in from behind and call out to her, though something seems... off about her.
 
Master: "Nero! I heard you were testing your new NP strength. How is it?"
Nero: "Incredible, dear! Truly! The enemies in the simulation stood no chance against my power! However, there's one small issue.."
Master: "Oh? What's the problem?"
 
At that moment she turns around and I immediately understand why she seemed off at first, as her augmented assets jiggle in front of me.
 
Nero: "Master! I'm fat as a cow! Look at me! You said I would gain *some* weight, but nothing like this! My chest and butt have destroyed this outfit, and I have far too much belly fat to even zip up the front!"
 
I understand now why Mash was embarrassed. Nero seems to have forgone re-materializing a larger outfit to prove a point.
Her breasts were easily more than double their original size and her butt grew enough to tear open her outfit's butt cleavage window to the point that most of it was on display for all to see.
 
Master: "I also only expected to get NP2! It would have only been *some* weight, rather than four Neros worth of fat. If it's any consolation, you look incredible to me."
Nero: "Th-that is true.. the Neros just kept appearing and appearing... I-i-i had no choice but to consume them, of course, but.. ohhh why must you flatter me so?! You too-good husband!"
 
She runs over and hugs me tightly, squeezing all of her new curves against me.
 
Master: "You're so plump and soft, Nero."
Nero: "Umu, if Master likes this body, then I am ok with it!"
Master: "I'd love nothing more than to stare at your bountiful curves in the open, however I believe you should re-materialize a bigger outfit soon. Some of the other servants were uncomfortable with you walking about practically naked."
Nero: "Eh..? I had not even considered such things! However, if Master likes this, then the other servants will just have to accept it!"
