[Macro Cock/Ball Growth, Endless Cum, Destruction]

"This worked really well on Hibiki and Kirika, and they're full of energy... So it should work well on me too, right?"

Elfnein stared at the SONG brand energy drink in her hand. She had done a lot to try and help the Symphogear Users by improving the bond they had with their relics, as well as general improvements that would help them deal with anything that the Alchemists threw their way. And it was partly why she had developed this drink...

It was meant to boost energy, so that her friends could fight better in a pinch. In case they were running on a few hours of sleep, or they were caught off guard by a sudden attack at night. And since it had really worked wonders, surely it would help her too.

Not that she needed it as much as they did. She was a Homunculus. The normal laws that pertained to Humans didn't apply to her. But that didn't mean that she didn't get tired or she didn't have to deal with her own issues. More importantly, if it really did provide as much energy as it should, then she could develop even better items and other helpful things for the girls. Either way, she'd win...

It's not like there were any side effects. Hibiki and Kirika didn't report any, so she was probably safe. And yet she still had second thoughts. She had never drank an energy drink before. What if it ended up overloading her with energy and made it impossible to focus because she couldn't sit still?

The thought ran through Elfnein's head for a moment. Before she just shook her head and opened the can, letting the fizzy sound escape the aluminum confines for a moment before she just chugged the entire thing in one go. This was what she had learned from Hibiki. Hesitation wasn't the way to go. She just had to trust her gut and do what she could...

The drink poured down her throat, and she let out a loud gasp and pant as she slowly swayed back and forth once she had finished it off. She couldn't help but blush a bit, as a powerful heat filled her. She had expected that much, as it was something Kirika and Hibiki had both told her about. A quick rush of heat, and then she'd be filled with energy. Yeah, she'd probably be able... to... run... a...

Elfnein dropped the can as she stared down at her crotch, where she laid her eyes on something thick and throbbing. It wasn't impossible to identify what was between her legs, but it was definitely still weird...

It was a cock. A thick, veiny cock that was about the size of her forearm. She hadn't even really felt it grow, but she could definitely feel the pleasure that came from having the air brush up against it. It made her blush from ear to ear, as she gasped and panted.

"K-Kirika and Hibiki said nothing about this..!" She honestly couldn't believe that they would forget to tell her something so important. Why would they forget to tell her about the fact that the drink could make her grow a cock? More importantly, what was she supposed to do with this? Carol never told her anything about handling cocks, she was far too busy trying to understand the world...

The young blonde bit her lip as she gazed down at the throbbing mass. She had to do something. And the best thing she could think of was just... carefully reach down and try and touch it. Carefully. Steadily. Without making things worse..!

Elfnein wrapped her hands around her cock... And immediately, her head reared back as she couldn't handle the pleasure. Her cock was beyond sensitive. Just a single careful grasp like that was enough to make her cum, as the poor girl let out a wonderful cry. Just as her cock let out the sticky contents churning around inside her balls, splattering that white stuff all over her wall...

And yet despite what one might imagine, the orgasm didn't make her go limp. Neither did the orgasm actually empty out her balls. She could feel the cock growing in her hands... And she could feel the heft weighing her down, causing her to gasp even more as she was pulled out of the afterglow of cumming for the very first time...

"N-No way... It's bigger..?" Elfnein muttered in shock. M-Maybe she should've called Hibiki and Kirika and ask if they were experiencing similar side effects. Surely they'd be able to help her too, they were both more experienced with something like this, if she were to believe Miku and Shirabe...

Or... Or maybe... Maybe she should just try and stroke a little. It's not like... It's not like things could get much worse if she stroked her cock, right?

Several emotions were pouring around inside Elfnein's head and heart. Worries that she needed to properly account for.  Needs that were quickly growing. Hypotheses and theories and everything that revolved around getting to know this cock between her thighs and then figuring out how much she could handle...

And all of it came crashing down as she gave into her instincts, and just stroked her shaft a little. Once again, it was far too much for her to handle. She let out another powerful and orgasmic cry, as she tossed her head back and started to cum. This time, her cock actively bulged, because her cum was that much thicker than before...

It was like she went from a burst of sticky seed slipping from her throbbing rod, to a proper hose-like flow from that thicker cock. A cock that grew bigger as it fired off, now about the size of her arm... And it was still going to grow, as were the balls between her thighs that now reached the size of a basketball...

Elfnein gasped and pulled her hands off her cock, barely close to lucid thanks to the shock of cumming so hard. She couldn't believe it. She simply couldn't believe that she was able to cum that fast... Not only that, she couldn't believe that she was still growing. Her cock wasn't small before, but now it was even bigger than Chris' cock, and hers was usually fully erect whenever it got to these kinds of sizes.

"I... I have to stop playing with my cock..." Elfnein muttered as she tried to think about anything else. She had to do anything but focus on her cock. Maybe she should focus on the fact that she didn't actually feel winded or exhausted despite how potent the orgasm was. Perhaps she should focus on the fact that it felt like she was even more energetic than before...

Maybe she should reach down and touch... her... cock...

Elfnein panted as she let the thought dwell within her mind. Her cock. Not anybody else's. Not Maria's. Not Tsubasa's. Definitely not Chris'. And especially not Carol's. It was her cock. Her shaft. Her penis. It was hers... And it looked so proud. So powerful. Practically begging for her to touch it again. So it could keep growing. So it could keep getting bigger and bigger, until it was as big as it could possibly be. Alongside those churning tanks below...

Her cock. Her cock was begging her...

And Elfnein answered. Grabbing hold of her balls with one hand, and then firmly grasping the base of her cock with the other. Massaging her cum tanks and kneading them to make sure that the production of her seed was at its most optimal, while at the same time forcing herself to cum just from grabbing her cock..!

Of course she started cumming. She knew that a simple firm grip was enough to make her climax. She didn't hesitate to let out a powerful cry, nor did she hesitate to let her cock point upward from how erect it was...

Every few seconds, Elfnein started climaxing again. And with every climax, her cock practically doubled in size. At least, that's what it felt like to her. She wasn't too focused on the minor details like the specifics of her growth. What she was focused on was entirely how good it felt. It felt wonderful. It felt phenomenal. The sensation of growing, the sensation of just giving in and letting the pleasure consume her, it was overwhelming and delightful.

So much so that Elfnein didn't focus on the after effects of her constant orgasms. Not the fact that the cum was raining down around her, nor the fact that it was slamming into the ceiling. The more she shot off, the more her loads grew. Both in terms of actual volume and in terms of thickness. So before long, a bit of dust started to rain down alongside the cum. All thanks to how violently she was cumming.

But she still didn't focus on that. All that she focused on was how good it felt. All that she focused on was the fact that she felt so wonderful. Cumming over and over and over, no matter what destruction she was bringing.

So what if the ceiling above her was being caved in by her cum being used as projectiles? So what if she was causing the floor above that to crack as well? SONG could pay for it, SONG could handle it! She just had to cum, cum, cum!

Elfnein was well and truly addicted. And the fact that her cock was about twice her total size at this point, with glowing veins lining that very same cock as it poured full of infinite energy that made sure she would never grow limp, didn't bother in the slightest.

No. She just kept on rubbing it. Just as she kept forcing her thighs together, which pressed down on the beanbag sized balls between her thighs. It felt so wonderful. It felt absolutely delightful..!

It didn't matter that the growth was causing the building to come crumbling down around her. It didn't matter that she could hear the flooding cum around her clog up the pipes. Nor did it matter that any cum that flooded into the city's sewers would clog that up as well, ruining the city below while being ruined above by her cock...

All that mattered to Elfnein was the pleasure. All that mattered to Elfnein was the growth and the delight that came with every moment that she played with her cock. All that mattered to her was that her cock was stretching further and further into the sky above, while the rest of her remained so painfully small compared to that infinite cock of hers. Not that it mattered that she was so small. The size of her cock was much more important..!

All that Elfnein wanted was to keep working on improving things for her friends. All that she wanted was to try and make things better for the people that she was close to, so that they could then make the world better too. And here she was. Ruining things, all thanks to the infinite energy that now powered her cock.

But the addicted girl didn't care. The only thing she cared about was the cock stretching into the sky above. Just like the other cocks in the distance that weren't as big as hers. The sight of which made her giggle a bit...

That was probably why she hadn't heard from Kirika and Hibiki. Not that she registered it as such. All she registered the cocks as was competition. And the cock-addict only saw competition as another reason to keep stroking and keep cumming. Flooding the city and making her cock grow bigger and bigger. Because that's what drove her.

Infinite growth. Infinite cum. Infinite pleasure. All fueled by the infinite energy that came from that energy drink. All because of a simple desire to help.

A simple desire that had been twisted into a simple lust, with no end to it or her growth in sight...
