The man that walks from the bedroom several hours later is not the same man who entered.
Nothing will ever be the same again after that experience. Rias and Akeno were already ruthless lovers, but to double their number is tantamount to madness. By the end, you were ejaculating dust. It was only when you visibly started to turn into a complete zombified husk that they decided it was time to call it quits and show you some mercy.
The four girls lounge around your apartment. One Rias is on the couch, another is still in your bed cuddling with Akeno, and the other Akeno is now occupying your shower. You are battered, you are bruised, and your dick kind of hurts. That's not the only thing swelling right now – because your ego is reaching dangerously high levels. You just got to bang four girls at once. You're kind of the coolest guy in the world right now.
In short, completely and totally worth it.
You pat down your pants to try and fight the dull ache going on down below. Sorry little buddy; this experience will hopefully allow you to come back stronger next time. Your phone vibrates, and before you can even swipe the green button and answer the call Mitsuru's voice blares through it – did she install an override on this thing?
"I've located the drone. It's hiding inside of the industrial area south of downtown." A map appears on screen and a green line stretches from your apartment to the target location. "Get down there and smash it before they cause any more trouble."
"Alright, looks like we're moving out." You hop up from the couch like a king, but you actually fall flat on your face instead. Your legs are fucked. It's a good thing your living room is carpeted. Couch-Rias leans down and pulls you back to a standing position with a giggle.
"I didn't realize we wore you out so much."
"Really?" you say sarcastically, "Come on. We're going!"
Kitchen-Akeno stomps her foot, "But I was just about to make dinner…"
"No buts unless they're on my face!"
----------------
After wrangling all of the girls, you hustle on down to the industrial area of the city to try and find the culprit behind all of this tomfoolery. Activity here has died down significantly since the nineties. It used to be the working heart of the entire surrounding area. Service industries had come in to fill the gaps. As a result of that and a lack of interest in re-developing the area for a new purpose, half of the district is now abandoned factories and warehouses. The most airtime this place gets on the local news is when one of them burns down thanks to a lack of maintenance or some kids screwing around.
Rusted steel, shattered glass windows and pipes running everywhere. Not the ideal place to bring two of your wives. You can hear a stray dog barking in the distance, along with the occasional bang or clang from one of the surviving businesses. It's a good place to hide – if you're so inclined.
"You're nearly at the target location. May I suggest transforming into your armour before the fight begins?"
Good idea Mitsuru. You press the button on Lala's bracelet and don the armour. Akeno and Rias and Akeno and Rias swoon over the sight of you in your noble dress, though you can't help but wonder why they find it so exciting when Issei can essentially do the same thing. Maybe they find the 'white and stained glass' aesthetic more appealing, or maybe they're just trying to massage your already bloated ego.
"This is the place," you say, looking up to a pair of open red barn doors. Inside is a completely empty warehouse space. Large metal struts run from the ceiling to the dirt-covered ground. A row of lights hangs limply from the rafters. You step inside expecting an enemy ambush of some kind, what you find instead is much stranger.
In the center of the gigantic space is a set of old, red furniture. A couch, an armchair, even a small matching coffee table. Atop the seats are the men of the hour. Faust and his duplication monster are watching the news on an old CRT TV. With the volume pumped up to max, it echoes through the cavernous complex and reaches your ears unbidden.
"Another attack today has forced a response from the Governor. He condemned the unknown force responsible for the damage caused, and attempted to dispel rumours of a 'superhero' arriving to save the day."
The image switched from the studio to a live feed of him making a statement, "We're already working to improve the security of our city. The police and national guard are on high alert, and are ready to respond to any further attacks by this unknown force."
"What about the superhero?" asks an unseen reporter.
The governor scoffs, "It'll take more than some internet hearsay to convince me of something like that. I can only ask people to apply some skepticism to what is clearly doctored and edited footage."
You sigh, "Why can't an honest guy get some credit for his hard work these days?"
Faust scrambles to grab the TV remote and switch it off. He turns back to face you with a look of shock on his face, "You, how did you find us?!"
"That stupid tin-can of yours is broadcasting a signal we can see from a mile away. Maybe you should turn it off next time you want to hide somewhere."
"Grr. All of this is your fault! If you hadn't interfered, we would have destroyed this planet through overpopulation already!"
"Uh. I'm not so sure about that." Far short of the mass anarchy that Faust had expected, it seems that people are getting along swimmingly with their identical copies. There is no panic, nor any suggestion that the city will soon be experiencing a shortage of food and resources.
Faust pauses, "How many people are on this stupid planet?!"
"…Eight billion, give or take a few."
"E-E-Eight billion!" he screams, "I can't clone eight billion people! I'll die of old age!"
Another body makes their presence known, sat above the party on one of the metal struts. Sundar sighs and covers his face, "You didn't even know that?"
"He has a point," Rias agrees.
"Why are you taking their side Sundar? If you aren't going to help me destroy these fools, don't pester me with your irritating presence!"
Sundar shrugs, "If that's what you want. I'll just sit back and watch as this guy kicks your ass." He crosses his legs over each other and leans back in a relaxed pose.
You've heard enough, "How about we stop this circus and settle this the simple way?"
"Fine! Copyroid, destroy that fool! Without cloning him this time!"
The mechanical man takes a fighting stance and charges at you. You hold out your arms and put a stop to its bull charge. You deliver a metal denting knee to its midsection and hoist it over your head, slamming it back down onto the ground and stunning it. Meanwhile, the DxD foursome decide to teach Faust a lesson using their magic.
There was never a realistic prospect of him winning this fight. In reality it's even more pathetic than you first imagined. Rias and Rias swoop in using their devil wings and pummel him with a flurry of glancing blows, while Akeno and Akeno strike at him from afar using their incredibly dangerous lightning. He can't even move due to the barrage raining down on him from above. And true to his word, Sundar doesn't lift a finger to intervene on his compatriot's behalf.
"This… isn't… fair!" he yelps.
"It's not meant to be fair," Rias teases him, "This is love and war."
He is struck by another bolt from above, "Ara, if you have such a problem handling four girls at once…"
And another from behind, "Maybe you shouldn't have cloned us in the first place!"
Meanwhile, you're putting your best foot forward against the mechanized man trying to beat your head in using its cannon as a blunt weapon. Chun-Li's training has already had an effect on your fighting ability. Your stance is much stronger, your blows using more of your body's natural power. Even as you take a stray hit from its other hand, you stand firm and strike back with just as much ferocity.
Each clang of fist meeting metal spurs you on even further. Nuts and bolts fly free from their housings as they begin to fall to pieces right in front of you. You polish off your left-right combo with a flying kick, sending it tumbling down into the dirt.
Your communicator beeps, "It's time for the finishing move!"
"Finishing move? The thing can barely even stand up!"
"I thought you knew better than that! Every good hero has a finishing move, the most powerful, flashy attack that they only unleash when the foe has already been defeated to the point of no longer being a threat. Seriously now."
Isn't that all totally ass backwards?
"You never told me anything about a finishing move before."
"It's easy. Just do what you did already but give it a silly name, the suit will trigger it automatically."
A silly name? She's really putting you on the spot now.
"Fuck it."
You charge at the monster. The meters inside your helmet begin to go haywire as power it rerouted from your usual subsystems into your left arm. The panels there open outwards and begins to spark with condensed energy. Your mind quickly queues together a series of words lifted from other TV series and anime you've watched.
"Super-Electron Poly Punch!"
The clumsily glued together statement works a treat. You jump into the air and come back down again, planting your strike dead-center on the android's chest. A second later your vision blanks out as a gigantic explosion engulfs both you and the robot. When the dust settles, little remains of it except a spattering of spare parts and mostly intact limbs.
Cringe. That was cringe. That thing you just said? Cringe.
You crouch down and clutch your ringing head with your hands. You're such an asshole. You should have come up with something better than that.
As if to punctuate the immense dread you feel - Mitsuru chirps back through your headphones, "Perfect! That's some great footage!"
"…Footage? Hey, Mitsuru – did you just close the call? Mitsuru!"
You glance up just in time to see Faust retreat from his fight with the four DxD girls. When he does, the copies begin to flicker in and out of existence like static on an old television. Then they are pulled together and merge back into one, complete person. It looks like destroying his android undid the cloning process.
A gust of wind sweeps past you, snatching away the intact cannon that it had once used. Sundar smirks cockily from atop his hiding place with it clutched under his right arm. "That was pretty entertaining. But that idiot Faust isn't the sharpest tool in the shed. Next time – I'll give you a real challenge. See you later!"
And just like that, he's gone too.
You sigh and detransform. Akeno and Rias glide back down to you and kiss you on both cheeks.
"We did it guys; we defended the empty warehouse from their evil ways."
----------------
Back at the lab.
"Well done everyone. Another interdimensional scheme foiled with peak efficiency."
"Hubby was very impressive today. That training is paying off," Rias smiles.
"Ara, I like a dependable man," Akeno giggles, "Please show me more of that side in the future!"
"Gap-moe?" Mitsuru ponders.
"That implies I'm not usually dependable," you object. You slouch down on the couch and try to rest your body after a long day of… sex. It was mostly just sex. The fight lasted no longer than four minutes of carefully segmented and produced screen time.
Mitsuru busies herself on her laptop with something, it's only when she turns up the audio and you hear your own voice under the slickly produced musical score that you realize what she's doing. "Mitsuru, you didn't just record that to make a toy commercial, did you?"
She freezes with a tense smile, "Ah. Didn't I tell you? I'm… recording these fights for… research purposes so I thought that it'd be helpful to turn them into DX toy ads."
"Mitsuru…" you repeat with a grave tone of voice, there isn't much else that needs to be said.
She ignores you and keeps editing anyway. You're going to have to get back at her somehow soon.
