NikkEvolution Pt. 03

Rapi started to finger herself at the thought that sex could be the key to growing bigger. It was a match made in heaven. Though she was still aimless for now, she gladly spent some time exploring her rampantly awakening libido. The way her muscled thighs now clamped down her fumbling hand, every stroke got her closer to the edge. With her other hand she went back and forth, cupping her breasts and ass, which both easily filled more than a handful. Supple yet firm and begging to be touched.

This orgasm was just what she needed to calm her nerves. Although it put only a dent in all the pent-up horny energy. It must've been dozens of minutes more of non-stop masturbating. At times Rapi switched her drenched hand so it could stroke and fondle her lubricated nipples. Hearing her moans forcefully escape only turned her on even more. She lost track of how many times she came.

Despite the overwhelming pleasure, her intuition was still active. It was getting dark outside, and predators could be lurking. Just then, Rapi made out some distant footsteps coming her way. She got up and readied herself for an encounter. Even now, she couldn't stop fondling. Bits and spikes of pleasure kept interrupting her focus.

Just outside, an injured Nikke came staggering towards the tent. It was Privaty, and she returned on her own after leaving behind the rest of the Commander's current squad. They were holding the line after an emergency mission kept them busy for most of the day.

"I can't believe it. The Commander must think I'm a total deadweight." The defeat got Admit feeling down both mentally and physically.

"This day can't get any worse..."

She flipped open the tent's entrance to be proven wrong just in time. There was no time for Privaty to even register what was happening. Rapi grappled the weakened girl around the neck, her bulging arms draining Privaty of any remaining standing power she had.

Rapi couldn't believe that she handily took a Nikke down like that. Did she get that much stronger since meeting Anis? Glossing over the many bruises Privaty was covered in, an intoxicating amount of confidence helped rebuild her ego.

...But what now?

It took Rapi a bit to collect her thoughts. The world was in a terrible state, and dangers lurked everywhere. So far things didn't go like she would've hoped they would. On her own, evolving and adapting made her feel right in all the things she did, but the rest of the world just made her feel out of place. She needed more of her kind to truly thrive.

Privaty still lay there. As Rapi took in her features, she felt empathy for all the pain she must've been in. Some of her clothes were ripped, and the breath escaping her mouth was shallow. Rapi's nipples perked up at the sight of that open mouth. It looked so inviting, begging her to plug it and let her suck on them. Whether it was out of kindness or to give herself the best shot at survival, Rapi sat down and guided the passed-out Nikke's head toward her chest.

"MMhhh" The first contact felt moist and warm. She'd never done this before, but her pheromones were working overtime to produce breast milk. Until then, she also just enjoyed the intimate contact she had with Privaty. Things never used to be this simple as a Nikke.

A trickle just dropped onto her tongue. Suffice it to say, all of Rapi's fluids were a direct product of her evolving cells, and as such were also carried over to transform Privaty. It was however unexpected what a single drop could lead to. In all their time adapting Rapi's sturdy psyche, the B.A.R.s dialed up their mind-altering capabilities to extreme levels. Now entering Privaty's defenseless subconscious felt like a work in the park by comparison.

It's as if her mind was wiped clean within seconds. Disregarding whatever sense of self she had left, her mind could only comprehend one thing anymore: Suckle. Drink milk- Get healthy. Help Rapi get big. Strong.

The transitions seemed to take place seamlessly. Like two brains sharing the same mind, they knew exactly how to coordinate. Privaty took the initiative by grabbing Rapi's left tit that she was still sucking on. Both hands were just short of covering their entire circumference. Rapi could feel the flow of milk picking up pace with each stroke and massaging motion. On top of that, she was so heated that she might just cum from her boobs alone.

"You're so fucking hot when you moan like that." Privaty noticed the one teat dry up, so she took a break before changing over. Chatting between Nikke was seen as superfluous. That's even more of a reason why giving a bit of dirty talk felt empowering and arousing at the same time. In the meantime, her thumb circled Rapi's right areola in anticipation.

"Drink up, bitch. AhHNGh Mommy needs you STRONG!...and ready for sex." Rapi teased her back. It was true that her milk was transforming Privaty to become an ideal mate. Under Rapi's protection, most of the growth was free to focus on her breasts and clit.

The moment Privaty resumed suckling, Rapi could feel an immense orgasm build up: "OohHHw!...Keep *grunt* keep goinnng." Privaty quickened her movements in response. All of her actions were basically an extension of Rapi's will since the contact with the B.A.R.s utterly subjugated her own.

Countless shivers of pleasure went through the tits she still had her head buried in. All this action made them jiggle only more, but the moment Rapi reached orgasm it was as if they had a will of their own. Rapi could feel huge spurts of milk suddenly fill up both of her boobs. There was no way she'd allow that much of her rich milk to get wasted, but the sensation was too overwhelming to hold back.

"I'm about to... HaAAhh!" bursts of milking escaped her throbbing tits, without any time to think, Rapi craned down her neck and sprayed her own mouth full of her delicious ejection. Even with Privaty's solid grip, white lines started to drool down her mouth, unable to contain every last drop. They rode this high for many more bursts of milk, only to be surrounded by a puddle of milk and sweat by the end of it.

Meanwhile, the Commander found himself at wit's end. It wasn't some big tyrant-class Rapture that stood in their way. The stream of common Raptures endlessly continued, draining them of any stamina and ammunition they had left.

"I know we put Privaty in danger like this, but we have no other choice." He ordered his squad to fall back on their last line of defense. Back at the provisional camp they had prepared.

Rapi sat across the room. Her now even thicker and wider looking ass felt better than any cushion. She realized now how much more potent her milk was compared to any regular source of food. She could feel it. Gradually changing and growing. Her breasts now encompassed her complete upper body. Standing up she couldn't see her feet anymore because of their sheer size.

Another proof of their growth lay passed out next to her. Privaty was still grappling with the situation. Beyond sex and lust, nothing else occupied her mind anymore. It would take the B.A.R.s longer to repair any resemblance of a well-adjusted Nikke. Rapi wasn't too worried about that though. What did catch her attention was the bulge that kept expanding in Privaty's crotch.

She's growing into a futa. Rapi wasn't even aware that they could evolve beyond just improving what their bodies already had to give. Their sexual encounter must've allowed for both of their horniness-driven cells to mutate uncontrollably. Privaty's already tight fitting uniform was stretched to its limits, as her not even erect bulge kept swelling. It's fast enough that Rapi could see it slowly expand as the minutes passed.

Taking in the moment, Rapi noticed a creeping tension covering her skin. She vividly remembers the feeling of growing, her bones stretching and her muscles expanding. This was something different. A layer of soft material formed around her curves, like a piece of lingerie. It stretched over her form-fitting curves, giving see-through glances even around the sturdier parts that held up her breasts and covered her crotch.

Rapi ached to explore these new powers. There's something particularly enticing to her when it comes to outgrowing her clothes. The moment she grew out of and tore up her uniform, a part of her old self was also conquered. Rapi was developing a lust for destruction. Before getting too indulged in her fantasy, she heard the rest of the Commander's squad approaching. She may have overcome her fears but that didn't mean she was blindly falling for a lost cause. Rapi wasn't a match for four Nikke at once, so She decided to get out the backside and momentarily abandon Privaty.

During her time in the tent, Rapi had complete control. She felt like a ruler of her domain, but a look at the outside world brought her back down to reality. The earth was littered with debris. No place for life to thrive in. She picked up the remaining shells of a broken Rapture. The smaller scouts were around two, or three feet in height. All of these human-hunting mechs had the same glowing deep red core, but this one was long turned off.

Rapi wanted to get used to her strength, so she squats down and attempts to lift the 200 lb scraps. Back then, her thinner Nikke arms could've easily taken on such weight. Her arms have now doubled in size but had to rely on raw muscle to apply strength. To her triumph, she managed to lift it on her first go. It was a unique sensation, feeling the blood pumping through her veins, wielding so much power. The moment she put it down, she noticed that her biceps still stayed so large despite being relaxed. Flexing it again made it look only bigger. Did her milk cause this surge of strength?

The rest of her arm was equally defined now. Her triceps stood out as well, giving her upper body a burly curvature. From her forearms all the way up her shoulders and traps. Rapi really got into the mood to let off some steam now. She began with pushups, but after she didn't slow down after the 30th, she went on to do 10 more one-handed repetitions for each hand before exhausting her upper body.

Afterward, she continued on with whatever other exercise came to her mind. For the first time, Rapi noticed how her increasing size, both for breasts and muscles, kept disrupting her movements and flexibility. She had to get accustomed to her wider frame. With every step, something jiggled. Moving her arms in cramped positions became difficult. All these issues that arose were just a testament to her growth. She took it all in with pride and looked forward to growing even more.

Meanwhile, the 5 Nikke were now all assembled in the tent. The mood was grim because of their recent defeat. Neither of them spoke a word, but Emma decided to give Privaty a look. After all, she sustained the most injuries and had to return earlier than the other 4. Emma was confused by her just laying on the ground face down. In truth, Privaty was grinding her cock against the ground, the collecting precum and length of her shaft had finally broken out of her constricting dress.

Before Emma came close enough to find out, the smell tipped her off. Rapi's pheromones still lingered, sedating everyone that breathed them in. On top of that, Privaty was still covered in a sheen of fluids, which looked entirely foreign to Emma.

"Girls, I think... I think Privaty might've been corrupted. By a Rapture." Emma mistook the injured Nikke's raggedly lusting motions as a writhing of pain.

"What? We have to tell-" Harran stepped closer, her nostrils widening at the pure smell of sex that lingered. "I mean... we should..." Her previously stunned expression shifted into a cross between dazed and tranquil.

"Or we just... wait until tomorrow. Maybe she's fine? None of this looks like a normal Rapture attack..." Helm stepped up and attempted to argue away their worries.

All three were visibly denting their tops with their nipples. Clearly, they had other things in mind than the state of their fellow squad member.
