"Can you clean up your trash when you're done?" Miku frustratedly asks her roommate.

No, not the roommate that was her beloved Hibiki. Hibiki was off on a mission gallavanting through the Gjallarhorn in search for another universe's Hibiki. it was her other roommate, the former goddess Shem-ha.

Similar to the remnants of Carol still left in Elfnein after her defeat, so too did S.O.N.G. find fragments of Shem-ha still existing within Miku. For several months Miku lived with the knowledge that Shem-ha lived within her subconscious, before Elfnein was able to find a relic with the abilities to exercise the goddess from Miku's body. When they used the relic on Miku they found that it did far more than just remove Shem-ha from Miku, it created an identical copy of Miku's physical form for Shem-ha to inhabit.

This Shem-ha was deemed no longer a threat to the world. Her powers were greatly diminished from the fight, leaving her a shell of her former self. Still, Her powers were too great to let her go unsupervised, so it was agreed that S.O.N.G would keep a close watch on the girl. What better place to keep her in check than under the same roof of the God Slayer Tachibana Hibiki. Thus Hibiki and Miku welcomed a third roommate to their home.

It is unnerving, suddenly living with someone who looks just like you. Like a long lost twin suddenly appearing, sitting in your seat, eating your food and using all of your stuff. It is the feeling of hearing your own voice in a recording but times a hundred.

Worse still, Shem-ha was a terrible roommate. Turns out former goddesses don't make good living partners. Inconsiderate, rude, and slovenly were the nicest things Miku could say about Shem-ha. The former goddess tested the limits of Miku's patience.

"Shem-ha, did you hear me? I asked you to clean up after yourself." Miku asks the former goddess sitting in their room reading manga while eating. Shem-ha adapted to the pleasures of the modern world surprisingly well. A lot better than Shem-ha adapted to listening to others.

Frustrated and tired, and with a ton of her homework still left to do, Miku takes her time to pick up after the former goddess and toss the several bags of chips and cans of soda into the waste bin.

"Thank you" Miku sarcastically says under her breath.

"Your welcome" Shem-ha replies without even stopping to read the manga.

Miku can't let that comment stand, it's the last straw in a cup full of straws, "No, you're supposed to say 'Thank you' to me."

It seems Miku's outburst is deemed worthy enough for Shem-ha to stop reading the manga and face Miku, "Why would I do that?"

"Because I cleaned up after you!"

"I didn't ask you to do that."

"It was a mess. Your mess."

"According to you," Shem-ha smugly replies, "Seems to me that you cleaned up the mess for your own sake, not for me."

"You've been living in our home for two weeks."

"That's not my fault. I didn't have any say in the matter. If I had things my way, I'd have reshaped the world in my image-

"And dissolved the barriers between all humans" Miku finishes for Shem-ha, "yes, I've heard it all before."

"Point is that you are not my roommate. You are my jailer and I don't feel the need to thank my jailer for cleaning my cell."

"Hmmph," Miku pouts exasperatedly. This conversation has already sapped more of Miku's time and sanity than it is worth. Later when Hibiki returns the two of them can have a talk with Shem-ha about manners. Until then Miku only needs to patiently endure it and not take any more of the other girl's bait.

"While we're on the subject of gratitude," Shem-ha remarks, "It occurs to me that you've never thanked me."

"Thanked you? For what?" Miku asks the vexing girl.

"For my gift, obviously"

Miku's mouth drops stunned at the audacity of the other girl, "just what gift are you talking about?"

"Oh, you know!"

"no, I don't…"

Shem-ha gestures with her head towards Miku's crotch, and Miku's face heats up. "You did that? On purpose?"

"Of course! What did you think it was, some accident with a relic?" Shem-ha replies with a matter of fact expression, as if it was a completely ridiculous assumption.

"Well… I mean, yeah." Miku timidly admits to Shem-ha, "like, what purpose would you have to make me an Alpha?"

As an unintended ramification of using the relic, Miku found that her secondary sex had changed from being an omega to being an alpha. At the time it bewildered Elfnein, but they all brushed it aside yet another side effect of untested relics. Elfnein promised Miku she'd find a way to revert the change. In the meantime, Miku found herself stuck with a dick between her legs.

Shem-ha beams with a smug smile as she haughty explains, "I told you, it is my gift to you for being my mortal vessel for so long. I gave you what you always wanted!"

"I did not want to be an Alpha!"

"NO!" Shem-ha shouts with the fury of once divine deity. "You can lie to your friends, you can lie to your family, you can even lie to your precious Hibiki but you do not get to lie to me! Do not forget your place. I was in your head. I saw all your thoughts. I witnessed your deepest dreams and wildest desires. You cannot hide anything from me."

"You can pretend to be the good submissive omega you've always tried to be. The one you thought you had to be. Deep down inside you I saw the fire that burns within. The fire that wants to claim Hibiki as your own. The fire of a true alpha."

"You're wrong…"

"Who are you trying to fool here? Have you seen the ass on that girl? Who wouldn't look at that perfect round bottom and want to fuck it. From the way the other Symphogear look at it, I know they would all agree."

"I'm not having this conversation with you." Miku retreats back to her homework. She can hear Shem-ha scoff at her, but Miku refuses to take the bait and continues to ignore the other girl. Shem-ha could never understand. She's an alpha. If all you have is a cock, everything looks like a hole to fuck. Miku was, is, an omega. She's hardwired to want to be filled by her mate.

Shem-ha breaks the silence with a question, "Have you tried taking it for a whirl yet?"

Curiosity gets the better of Miku as she responds, "Taking what for a whirl?"

"Your dick, obviously."

Miku's face once again bursts red as the conversation returns to her genitals. "That is none of your business."

"It was a gift from me, I want to make sure you are enjoying it," Her twin replies once again with the self assuredness that can only come from the divine.

Miku's head hurts as she tries to follow the logic in Shem-ha's statement. Eventually she decides to take the path of least resistance and tells the former goddess, "No, I haven't… masturbated with it."

"Really?"

"Really."

She can feel her twin's stunned gaze even without looking at the girl. "This is a gift from a goddess! It is rude to not use it."

"Well, that's my problem." It's not like Miku hasn't been tempted to play with her new equipment. For purely scientific reasons, of course. There hasn't been much of an opportunity to do so. She's only had the equipment for a couple weeks. Hibiki and Miku have struggled to find time to even have sex with Shem-ha's presence at their home meaning they have a lot less alone time.

Shem-ha sighs loudly with a frustrated tone, "I suppose I shouldn't be surprised. Your relationship with your precious Hibiki has always been so saccharine it makes me want to vomit. Of course even when you have been gift wrapped the tool to have what you desire you'd still be too timid to actually take it."

"I suppose if you want something done, you have to do it yourself." Shem-ha states before standing up and approaching Miku.

Miku finally notices Shem-ha when the girl turns her revolving chair to face Shem-ha. "What are you-"

The sentence is silenced by Shem-ha pressing their lips together. Miku freezes, completely stunned by the action the other version of her has taken. Kissing Shem-ha was nothing like kissing Hibiki. When kissing Hibiki she could always feel the girl's desire tempered with caution and care to not hurt her. Shem-ha's kiss is needy and demanding. Like everything Shem-ha takes what she wants and demands submission. Miku can't help but submit to the girl.

Shem-ha pulls back from the kiss and gazes at her. Miku can only imagine what she looks like, flustered and dazed.

The former goddess then drops to her knees between Miku's legs. She pushes her skirt up and pulls her panties down to free the hard dick underneath. Miku is ashamed to admit that she got an erection from the kiss with her other self, but it was undeniable when looking at the evidence.

Shem-ha wraps her hand around the shaft and gives it a few pumps. A moan escapes Miku's lips as Shem-ha's soft cool hands play with her cock. It's long, maybe even longer than Hibiki's own erection. It's not as fat as Hibiki's spear.

"Look at this magnificent tool I've given you," the former goddess smirks as she looks at her handiwork. Her twin looks so smug as she watches Miku squirm under the fingers. "Let me show you all it can do"

Then Shem-ha takes Miku's virgin dick into her mouth. Her twin's warm mouth enveloping Miku feels better than the young girl ever could have imagined. Miku knew in her mind that blowjobs felt good. She could tell that much from how much Hibiki seemed to enjoy them whenever Miku gave her one. Knowing something feels good and experiencing it are worlds apart. It took all of Miku's self control to not explode right on the spot.

Miku has no clue how the goddess got so good at giving head. Was it practice from a past life? Was it something she picked up from being in Miku's head for so long? Or Is it just one of her godly abilities? Is Shem-ha really the God of the Earth and Blowjobs?

It's a surreal experience being sucked off by someone who shares your same face. Seeing your own lips wrapped around a hard cock in such an obscene manner. To feel her own mouth pleasing her in this forbidden way. Miku knows that this must be what Hibiki sees when she goes down on her girlfriend. This pleasure is the same pleasure that she gives Hibiki. The thought of being even closer to Hibiki causes her erection to get even harder than it previously was.

Every now and then Shem-ha would lick up the shaft and watch Miku watching her. Miku gazes into those eyes. The rest of Shem-ha's body was the same as Miku's, but the eyes were distinct. The look her twin gives as they hold Miku in the palm of her hand, like a toy to be played with, is one of pure dominance.

Shem-ha continues to do this for a while, bringing Miku to the brink of pleasure with her mouth before pulling back to watch Miku beg. Over and over again, Shem-ha denies Miku the sweet release she so desperately desires. With her eyes, Miku can see Shem-ha goading her on.

Finally the need to cum becomes too much to bear for Miku. The young girl grabs the back of Shem-ha's head and shoves her cock down her twins throat. Roughly, Miku pulls Shem-ha up her cock before shoving her all the way down until Shem-ha's nose is in her pubes. She no longer cares if her twin chokes on the cock, she no longer cares if it hurts, all she cares about is finally achieving her climax. With that goal in mind, Miku continues to fuck Shem-ha's face.

It doesn't take long for Miku to reach her climax. She was already on such a short fuse as it was. Harshly, Miku shoves her cock as deep as it can go in Shem-ha before he releases her seed straight down her throat. Load after load of semen goes straight down the throat and into Shem-ha's stomach for what feels like an eternity before Miku's climax finally fades and she collapses.

With Miku's release on her head gone, Shem-ha can finally pull herself off the softening dick. Her cheeks have tears streaking down them and her lips are swollen and messy with saliva and semen, but her eyes burn bright.

"See, you do enjoy the gift I gave you." Shem-ha says with a smug satisfaction of someone who proved herself right.

"Fuck. you." are the only words that Miku can muster between heavy pants.

"In good time. In good time." her twin smiles back at her. "First, let's move this to someplace more… accommodating."

Shem-ha helps Miku over to her and Hibiki's bed. There Miku's twin strips her of all her clothes. Then Shem-ha takes off her own clothes and joins Miku on the bed.

Miku on the bed facing up. Between her legs is Shem-ha giving her another divine blowjob. Having already climaxed once sates Miku's desires enough for her to enjoy the heavenly mouth servicing her. Having a goddess worship her cock so thoroughly was a huge turn on for Miku. She tries her best to etch the other Miku's techniques into her mind so she can try them out on Hibiki later on.

Once Miku has returned to full mast, Shem-ha pulls herself off the cock, glistening wet from her saliva. "I think this is good enough for now"

Shem-ha climbs up to sit on Miku's lap. Shem-ha's matching cock slaps Miku's flat belly as she takes her seat. It feels weird for Miku to admire Shem-ha's body, after all it's a copy of Miku's own. Even so, Miku can't help but enjoy the body before her. The athletic runner's body is lean and thin, but still hides a deceptive amount of muscle and power beneath the soft white skin. Her abs might not be as prominent as Hibiki's powerful fighter build, but they have their own definition. Shem-ha or Miku's breasts are on the modest side of things, but fit her nimble frame.

"Are you ready for this?"

Shem-ha reaches behind her to grab Miku's hard shaft. Carefully, she aims it towards the tight ring of her anus. There is a wall of pressure at first, but then the head slips in.

"Fuck!" Miku exclaims uncontrollably. It's only the head but Miku understands why Alpha's are always thinking about sex. The blowjob doesn't even compare to the feeling of her twin's anal walls clenching around her. It takes all her willpower to not try to shove the rest of her cock in Shem-ha's ass right there, and she doesn't want to hurt the other alpha.

Not that she could move too much with Shem-ha holding her in place. With only a hand on her stomach holding her down and a determined lustful gaze, Shem-ha makes it clear that while Miku is doing the fucking Shem-ha has all the power right now. The former goddess slowly takes her seat on Miku's cock, carefully impaling herself on the other girl's cock inch by inch.

The feeling of being inside someone has Miku writhing in pleasure. It's a completely new sensation for her brain to wrap around. It is as if the other girl is embracing her all over, holding her tight. Her other self's ass is impossibly tight and warm. Miku can feel the muscles sucking her in, massaging her from all sides. It is completely different from the sensation of having her pussy filled, but no less potent.

Finally, Shem-ha's ass reaches Miku's pelvis as she fully sheaths herself on the hot rod. Miku can see in Shem-ha's expression, through the layers of smugness and pride, the hints of pain and pleasure slipping through. Once Shem-ha feels comfortable with the shaft inside her, she begins to move her hips, barely an inch at first and keeping a very slow pace. Up and down, a small circle with her hips, the up and down.

Miku's not sure where she should be looking. The blissful expression of pleasure in her other self's matching face, the slight bouncing of her modest breasts, the way Shem-ha's powerful muscles can be seen moving under skin glistening with sweat, the neglected hard cock of the former goddess bouncing and dripping with precum, or the sight of her own hard cock appearing and disappearing inside the tiny frame of the other girl. It's all so much to take in.

Shem-ha takes Miku's hands and puts them over her body, "It's okay to touch."

Miku nods and listens to Shem-ha's advice as she explores the other girl's body. Her hands explore the soft curves of the other Miku, from her powerful thighs up to those pert perky breasts of hers. She spends a lot of time on her breasts, feeling the soft supple skin under her fingertips. When she plays with the hard tips it makes Shem-ha shiver. It's small, but Miku likes being able to force a reaction from the usually commanding goddess. It makes her feel powerful.

Her other hand goes down to Shem-ha's lonely cock bouncing away and strokes it casually. Delicious looking precum dripping from it falls all over Miku's belly. Her mouth waters as she looks at it, wishing she could suck it. Miku feels some comfort in the desire, some stability in it. Just because she is an alpha now who can enjoy fucking doesn't mean she can't also still enjoy having a cock fill up her mouth.

"Can you imagine it?" Shem-ha interrupts Miku playing with her new toys, "That it's not me but your precious Hibiki with you, fucking herself on your hard cock for you."

Immediately Miku's cock twitches inside Shem-ha. She can't help herself. Her mind is filled with images of Hibiki's hard body impaled on her dick. Miku imagines the way her bountiful breasts would bounce for her as she moves. How tight Hibiki's ass would feel wrapped around her dick. The look of ecstasy on Hibiki's face as Miku fucks her.

"See, I knew you wanted this." The girl with a cock inside her ass says victoriously.

"Shut it!" Miku replies, moving her hands from Shem-ha's torso to her hips. With her grip on Shem-ha's hips, Miku shoves them down on her cock forcibly.

"Eep!" The former goddess lets out an uncharacteristic cry as control is taken away from her. Miku lifts Shem-ha's hips up off her cock, before slamming them back down and forcing another reaction from the goddess. With this, Miku is able to control the pace at which her twin moves.

Miku finds it incredibly empowering being able to elicit such lewd sounds from a literal goddess. A divine entity that had nearly conquered the entire planet, now bouncing on her cock like an omega begging to be bred.

"Come on, you can be rougher than this" Shem-ha instigates, "stop playing with me, and fuck me already."

Some deep part of Miku that she's never felt before growls at the challenge. These new alpha instincts inside of her refuse to let that challenge go unprovoked. Unceremoniously, Miku rolls them over so that she can be on top of Shem-ha. It takes a moment to adjust the positioning so Miku can find the right angle of attack. Once she does, Miku fucks her twin's ass in earnest.

Miku's pace picks up, her strokes more measured and steady now that Shem-ha's insides have adjusted to the shape of Miku's invading erection. She rocks back and forth in a smooth slow rhythm, her hips meeting her twins behind with a soft slap after each thrust.

Any sense of composure on Shem-ha's part fades away as raw pleasure takes over. The former goddess is left writhing in pleasure, eyes closed and hands gripping onto the sheets to try to hold on as Miku continues to pound into her ass again and again. Any witty remarks that would come from her have been replaced by a song of loud whimpers.

Miku finds the angle that makes Shem-ha moan the loudest and continues to pound there. Remember how she likes to Hibiki to fuck her, Miku makes sure to switch up her pacing every few beats to keep Shem-ha on her toes.

Sweat drips from Miku's forehead onto Shem-ha's body. Miku can feel her muscles beginning to ache from the prolonged fucking. She's thankful for all her track and field practice building up her stamina otherwise she might have collapsed already. It amazes her that Hibiki was always able to last as long as she does.

Shem-ha senses Miku's pace slowing down and wraps her legs around Miku where she can help push Miku in deeper. Between heavy whimpers, Shem-ha utters, "Don't disappoint me now. You were doing so well."

"Will. You. Just. Shut. UP!" Miku accents each word with a powerful thrust, with the final thrust pushing Shem-ha over the edge. Miku can hear Shem-ha scream even as she can feel her twin's ass spasm as it squeezes her cock tightly. Shem-ha's cock erupts semen all over her belly and chest.

Once Shem-ha's orgasm has passed through her, Miku resumes thrusting into the other girl. Shem-ha murmurs annoyingly, but otherwise doesn't protest. With the former goddess sated for now, Miku can focus on reaching her own climax. With that singular goal in mind, Miku ruts into her twin's ass again and again.

Shem-ha's insides-her own insides- feel blissful as they grip her cock so tightly. In the back of her mind Miku registers that idea that the ass she is fucking so roughly is an exact duplicate of her own should bother her. It doesn't bother Miku, though, if anything the thought excites her.

This is more than just a Miku's ass, this is the ass that Hibiki fucks. This tight hole is the same hole Hibiki sheaths her spear in. These muscles massaging her dick are the same muscles that milk Hibiki dry. This is more than just her pleasure, this is Hibiki's pleasure. This is the pleasure Miku gives Hibiki every time they have sex.

With that thought Miku comes undone. With a final few thrusts Miku erupts deep inside Shem-ha's body. Miku can feel her sex throb as it shoots out spurt after spurt of her seed deep inside the other girl. If Shem-ha were an omega, Miku is sure she'd have impregnated the girl.

Only afterwards do the waves of exhaustion finally catch up to her. Slowly but gently, Miku slips out of the other girl. She groans as she leaves the warm insides of the other girl. Miku flops onto the bed next to Shem-ha, pushing the other girl a little to accommodate her.

Laying on the comfort of her bed gives Miku the time to process what just occurred. She enjoyed fucking someone. Like, really enjoyed it. It didn't feel like a mistake or an accident. If anything, Miku wants to do this again. And often. Not the Shem-ha part, though Miku wasn't opposed to having sex with Shem-ha again. If the other girl behaves well. But Miku wants to share this feeling with Hibiki.

Miku wants to fuck Hibiki's ass.

"Miku" Shem-ha calls out sluggishly

"Yes, Shem-ha," Miku replies as she drowsily turns to face the other girl.

"Thank you for all the cum."
