NikkEvolution Pt. 02

*The Next Day*

"Commander! The Commander needs my help~" Rapi woke up without missing a beat. Her long slumber was quite restful, even if she kept mumbling in her sleep. The main cause for her upbeat mood was probably the initial sign of her second puberty causing mood swings. Now that the B.A.R.s laid the groundwork, it was time for further action.

As confident as she can be, Rapi gets ready to do some paperwork for her commander. Even if she has yet to see how the experiment is going to take visible effect, Rapi could sense an odd feeling of confidence, now that her negative thoughts were taken care of.

During her diligent work, Rapi started to notice a pattern in the past combat report:

Privaty. Emma. Guilty. Harran. Helm... And the list went on.

Conflicting feelings roused within Rapi. These were her friend and allies. And yet, she couldn't help but see them as her direct competition. Rapi should be the one that deserves to stand next to the Commander... To call him her own. To take him as her mate.

Now that the B.A.R.s spotted a concrete obstacle, a fire was ignited. Rapi's animalistic side now did its best to portray these other Nikke as a threat that she had to overcome.

"I never notice how tall Harran is..." Push!

"Emma's breasts were always bigger than mine..." Push... -Push!

"Ooouh...! Why can't I look as mature as Helm or Guilty?"...Push.

"Fuck! I need my ass to be even bigger than Privaty's so Commander can bury his face, and I'll pound on his cock until he CUMS!!"

Rapi began touching herself at the sheer amount of lewd thoughts flooding her mind. Despite never acting like this around others, she didn't feel like the adaptive cells were bending her will against her own volition.

In truth, Rapi could never fully extinguish that seedling of jealousy whenever she spotted another Nikke around the Commander, just hide it. Coordinated as they are, the B.A.R.s worked on removing Rapi's inhibitions around that jealousy.

All this jealousy is an intoxicating boost for the adaptive cells. In combination with the increased sexual urges cause by her recurring puberty, the floodgates now opened for the B.A.R.s to push Rapi's body to outclass those other Nikke. A strong connection was paved between her sexual anatomy and her brain's pleasure center.

"Ugh. Getting hungry again." Rapi noticed with a pat on her taut stomach. As if a flip just switched, she didn't care about the Commander's papers anymore. If anything, she needed to meet him in person.

With more force than expected, she tossed the pen she held and took another trip to the kitchen. Luckily, there was still a lot left for her to feed on. Yesterday's meal was hasty and out of necessity, which is why she mostly went for the easily accessible stuff.

The changes from last night also helped her out: Today she's reaching higher spots on the shelf as she stretched her longer body, and making quick work of the more durable packaging with a flex of her stronger arms.

"Hmmmh... Better... Bigger. Yes..." Rapi moaned in between the loads of various meats and vegetables she consumed. In the past, she would've never behaved like this. It used to be a sign of weakness to her to just give up and let one's inner animal run rampant. Now that concept seems insignificant to her compared to the big steps she makes in humanity's evolution.

The scientists knew that fundamental changes were necessary to create something greater than a Nikke. Their programming made them subservient and predictable but also gave them limitations. Rapi didn't need to feel that self-conscious anymore. From now on, when she'd feel inferior, it would fuel a carnal desire, and only growing bigger could satiate that.

"Hngh... Fuck yes." Rapi was pleased with herself and cradled her stuffed belly. At first glance, it might look like she's several months pregnant, but the soft ripples that run through her flesh tell that it's all stuffed with tasty nutrients. A slight blush filled Rapi's face at the thought of actually becoming pregnant. That's what evolution was ultimately about: Creating offspring.

"Haaangh..." A guttural yawn concludes Rapi's feeding session. Her curvy backside and strong upper body let her comfortably rest right then and there on the kitchen floor.

*Nighttime*

The Commander's ongoing operation left the place eerily empty. Except for the kitchen. Rapi's snoring was only sometimes interrupted by her bouts of lewd moans. Even if you couldn't see her lying there in the pitch dark, you could hear and smell her. The room was lightly clouded in a fragrance of sweat and sex. Her ongoing puberty has entered the point at which pheromones are constantly released to lure in any potential mates.

Hour by hour, Rapi's changes could be spotted by the naked eye. She inched longer and outwards on the floor. Longer legs and wider hips swallowed the cold ground beneath and only left warm, sensual flesh. Her trap muscle and shoulders also developed further, giving her newly expanded F-Cup breasts the extra support they needed. Almost every bit of yesterday's feast was consumed by the greedy B.A.R.s.

Rapi started the night at 5'7" and with a burstingly full belly. A third of it got absorbed as she grew to 5'9". Another third brought her close to 6 Feet at 5'11".

At this point, her clothes were entirely too small for her, revealing skin every part of the way. Finally, the growth ebbed out at an even 6'0", as some of it got reserved for a possible emergency. For what it's worth, her shrunken abdomen also revealed the outlined beginnings of a 4-pack of abs, filling out her more than just an athletically built body. The fat was better off being stored in her chest and ass, which looked firmer than ever thanks to her overall increase in musculature.

*Daytime*

Rapi decided that it was time to go out and find the Commander. Her hunger for sex was only growing vaster alongside her size. Looking back at the kitchen, leftovers of squished bananas, zucchinis, and even an aubergine that's been drenched in fluids show that Rapi's patience was running out.

"Fuck!" Speaking of which, it seems that she can't properly put on her combat uniform anymore.

Her jacket is a really tight fit, barely passing through her wider arms, and struggling to button up her almost head-sized boobs. There was no hope for it to cover as much as it used to, as her longer upper body caused her midriff to be clearly peeking out.

Her skirt gave her fewer problems since her thighs and her hips had just about caught up to her former dimensions - Except for her thigh-high stockings, which now only reached the upper end of her knees thanks to her longer legs.

Lastly, Rapi had to give up on her heels. The way she placed her foot beside them was a clear indicator of growth so far. None of her toes would fit into these tight confines. The proportionate growth also made it so her foot's wider sole would struggle to find proper space.

All this extra effort made Rapi question what even the point of getting dressed is. It felt ingrained in her behavior to still uphold a sense of formality. Another memory also gave her pause. She remembers the Commander complimenting her outfit. As the B.A.R.s channeled their growth from Rapi's interpretations of the Commander's ideals, they now also worked on replacing her heels. Even in her idle posture, Rapi would unintentionally show off her curves by sticking out her front and back just a bit more.

With all that done, she makes her way out of the outpost. One of the papers from earlier just so happened to include the Commander's planned route. By late afternoon they were set to make a stop somewhere nearby. Usually, Rapi would have to make a request to be also part of that operation, but her urges couldn't be contained for that long.

"Why would I need to follow their pointless orders anyways? I'm not a Nikke....Anymore."

Rapi still felt resentment because of the way she was stripped of her identity. The B.A.R.s influenced her judgment to seek out more conflict. She couldn't make the connection that the changes that went on in her body were also thanks to orders she was given.

"They think I'm still blindly taking their orders. But I'm better than that..."

Rapi was almost out of the outpost when a familiar face called out for her. It was Anis, one of her squad mates with whom she spent countless missions fighting side by side. Anis didn't have to get close to her to see something was off. But only as Anis approached her, did she register the severity of the changes. Rapi was a whole head taller than her now!

"What happened? Did those freaks from the lab do this to you?"

She pulled her friend closer, taking in the stern look of determination that remained unfazed by Anis' appearance. What did startle her, was the unexpected amount of force that Rapi felt when she was grabbed by Anis. In her limited experience, she wasn't aware that humans were so much weaker than Nikkes.

"Uh, no. I'm... fine." Rapi musters a smile despite feeling a bit threatened. It's not like she fully understood the situation herself, so there's no way Anis would understand. "I just felt like going out for a bit. Don't worry."

"Don't worry!? They said you'd be in bed for like two weeks! We gotta go back and-" Anis reached out again, earnestly trying to care for her partner's well-being.

"No." Rapi returned the shorter girl's advances by coming closer herself. Their bodies were touching, and their difference in height was dominating the conversation. Slowly, Rapi's feet gained support from underneath, raised by fractions of an inch at a time, as if still wearing heels. By now, her breasts were closing in on Anis' face, the full cleavage squeezing against her collar. Her clothes felt even tighter than they did a moment ago.

Whether it was the absurdity of the situation or the commanding aura that Rapi and her pheromones emanated - Anis was speechless.

"Don't. Bother me again. I go now." Rapi's deeper than usual sounding words now reflected her confident demeanor. She didn't need to be stronger than Anis to establish that she was the alpha. Everything about her looks spelled out superiority. This survivalist attitude was infectious to the point that it gave Anis a taste of that very same fear.

This little encounter drained the B.A.R.s of the last bit of reserves they'd secured. It wasn't apparent from her behavior, but it took someone with remarkable willpower to not fold under such pressure.

*Later*

In her nutrient-deprived state, Rapi's cognitive capabilities have worsened by the minute. She wasn't sure how long she's been out for. By now, her evolutionary cells have finished covering every part of her. A steady blood flow of them circulating every fiber. A touch of her growling stomach confirmed her premonition. All used up, and just 4 properly developed abs in its place. Any worry about starvation was drowned out by a wave of excitement celebrating her progressing muscles.

"Strong. Stronger." Rapi moaned while caressing her abdomen. She tensed up to have her abs feel even harder and thus more satisfying to touch.

As fate would have it, the growing girl's tenacity was rewarded. The Commander's military-grade tent was just a bit further downhill, and she made it without encountering any Raptures. It's a bit darker than she'd expected it to be in the afternoon hours. A distant sunset gave the tent's lights an inviting glow.

Was this it? Finally meeting the commander? But what will she tell him? The other Nikke will be there too, right?

What remained of her sense of doubt and caution rang all the alarm bells. To a point that even though it came from the deepest reaches of her consciousness, the B.A.R.s didn't have the resource to fend them off. Simultaneously, her steps kept going at an unwavering pace, as if possessed. Rapi was now within arm's reach of entering the tent. This overwhelming sensation caused a mental short-circuit that left her thoughts paralyzed.

She stepped in. Her mind was still reeling, unable to take in the room's presence. It would take her a bit to process this revelation, but the tent was indeed empty.

Empty. Like the B.A.R.s previously did with her problematic emotions, they had to discard them. Make room for more willingness to thrive and grow. They were confident with their aggressive alterations but didn't account for how devastating it would feel for Rapi to lose that part of her that deeply cared for the Commander.

It wasn't about his looks or his strengths, but his attitude. His efforts represent the hopes that Rapi holds on to. All of humanity was stuck in this war for ages, and it was a tall order for anyone to single-handedly bring about peace. Rapi could feel her anger build up. Her transformation has gotten to a point that this anger resonated within every part of her, like a cornered animal.

"ArGhH-GaAAhh!" As her tension rose, she could feel her clothes become unbearably constricting. There was no imminent danger, yet she bulked up to put her dominance on display. *Rrrrripp* First to go were the inner parts of her sleeves, revealing her bulging biceps. *Fffwip* Her backside quickly followed, creating a gaping split right down the middle.

There wasn't much else to let out her aggression on, so she finished the job and tore apart her remaining clothes until their tatters littered the ground.

Rapi took in her body. Especially her muscles, which now responded to her every move. Proudly standing out like they only could after countless gym visits.

It felt good feeling powerful, but the nagging from before still soured her mood. Just like before, she returns to her habits and goes scavenging for food to distract herself. It didn't take long to find a pair of emergency rations, which she selfishly indulged herself in. Then again, this barely could substitute a normal meal for her, and she definitely needed more to get even bigger.

There was no way she could find anything edible close by since the constant battles left only scorched earth to wander. It all came back to the damned Raptures. It was apparent to her now that she'll have to somehow adapt beyond conventional means of sustenance.

"...Want food~." Push.

"Want Sex." ...Push

"Need. CUM."
