CHAPTER 18

A week had passed since Nikki treated Brad to a quickie and a show for his birthday and, surprisingly, life was trending back to some semblance of normalcy.

Professor Riviera had returned from questioning and was back to teaching, and the men in black were no longer prowling about town. Nikki wasn't exactly a paranoid sort herself, even with her sweeping biological changes, so she didn't think much of it; she had more pressing matters to attend to, and she always thought herself above tin-foil conspiracy theorying anyway. Prof. Riviera was the same as ever (though he declined to comment on the sort of questions the men in black had for him; he just left it at , and getting back to a university rhythm was welcome after the more recent trauma Nikki had endured.

There was once a point where Nikki felt hesitation, even terror about her new alien form. The ever present ooze that had to be navigated around, the tactile sensations of everything around her, the static buzz of half a dozen appliances integrating with her. She was far from human at this point, more machine than woman. But the worst of it was behind her. She felt more comfortable in her own body; there was a fluidity to her movement that wasn't there before. She had settled on creative solutions to her issues regarding her own conservation of mass. And Brad was in her corner, as unconditionally loving as ever.

Just for tonight, she didn't have worries about going out in public, how to sate her own urges, how to avoid causing public scenes. She did have to worry about that dumb school open house, but that doesn't really count, does it? No, she was more preoccupied with a rather silly conversation with Brad on her way home from university.

"You hear they're making a Transmorgrifiers 2?" Nikki beamed, dressed in her usually hoodie-and-jorts combo, her twintails playfully bouncing behind her.

"Already?? They just came out with the first one and they're already making sequels...?" Brad rubbed his head, confusion written visibly on his face.

"Yeah, sounded like they were already planning a whole trilogy." Nikki explained. She leaned in a little closer, fluttering her eyelashes. "We should watch them all in a row and snuggle~"

"Hones'ly I feel like I need to rewatch the first one. It was kinda hard to follow... no thanks to a certain someone." Brad gave Nikki a look; she responded in turn with a playful jab to the shoulder.

"Ohhh you liked it!" She cackled, her shoulders bouncing. "...Ah, I guess it was pretty... thick. I didn't know giant fighting robots cram so much philosophy into its runtime."

"I guess filling an entire movie with explosive special effects and CGI has gotta be pretty expensive." He shrugged. "And all those moving parts... wow."

"I bet I could pull off that kinda look..." Nikki cocked her head, tapping her chin. "Stomping through downtown Bismarck like Godzilla-"

"Godzilla terrorizes Japan, not North Dakota," Brad chuckled.

"W-well, can you name a movie monster that would?" Nikki puffed her cheeks. "Gettin' awfully pedantic over catastrophic property damage."

"Uhhh..." Brad thought about it. He casually pulled out his phone,typing in a quick search. "...huh, the Rampage movie tears Peoria apart-"

"Heyyy, that's cheating!" Nikki leaned over with grabby hands. "No cheating, give it here!"

"I'm not giving you my phone!" Brad used one of his beefy arms to hold Nikki at length. "If I did, there's no way I'm ever getting it back..."

"Eh, s'fine, I already ate." Nikki shrugged. "Ah, my apartment building's coming up. But I guess you gotta head straight to work, huh?"

"Yeah, hours are nutty lately. Manager put out a buncha radio ads, and a lot of newbies are coming in lately. Somebody's gotta be a good shepherd to the new flock." Brad sighed. "How about you? Got any exciting plans tonight?"

"Eh, girl stuff mostly." Nikki shrugged again, though this time the corner of her mouth had curled into a slight smile. Brad picked up on it—no matter what happened to Nikki, her poker face was always terrible—and opted not to bring it up.

"Haha, alright." Brad smirked. "Don't get into too much trouble, alright?" Brad waved jovially, hoisting a gym bag on his back as he increased his pace. Nikki stopped next to the front door, waving right back.

"See ya laterrr!" She piped up cheerily before hurrying into the building. Truthfully, Nikki had an ulterior motive for pursuing a night all to herself. She hurried over to her mailbox in the lobby, glancing around to make sure there was no one coming or going; usually there weren't any people hovering around this area.

...Mm, yea, coast looked pretty clear. She raised her hand in a finger-gun motion, her index finger shifting and tingling until the tip formed into a metal key—her mail key, to be precise. She ended up shlorping those up by accident a while ago, but it did make it convenient to have them on hand at all times. She unlatched the lock, finding another set of mailkeys.

"Ooh?" Her eyes lit up; nestled among the various mailed ads was a set of keys to one of the larger parcel compartments. She was careful in handling the second set of keys to check the compartment...

"Ooh!~" She clutched her arms against her chest, finding a conspicuous brown package, addressed to her. She knew exactly what it contained—a little treat she ordered online for herself. Taking the package and returning the extra key to the mailslot, she hurried up the stairwell to her apartment.

Letting herself in, she bumped the door shut behind her, her hand reaching down to make sure the metal latch was locked tight. She flicked the lightswitch to get some light going; ever since the incident, she had made sure to keep the curtains drawn.

Nikki relaxed, letting her backpack liquidate and slip down her backside; it plopped to the floor, a hefty mercurial mass that spread around her ankles, pooling across the linoleum floor of her apartment. She stretched her arms above her head, boneless limbs coiling around one another as she arched her back, her clothes melting away as the texture of her flesh smoothed out.

"Ahh..." She exhaled, drinking in the afterglow of her full body stretch as she flopped to the floor, casting waves as she slowly sunk into the expanding puddle of mercurial ooze. Her legs fused together behind her as she lowered herself to the ground; her twintails writhed and twisted above her, the tips flexing and morphing into extended, grabby hands with almost cartoonish proportions.

She rose a hand to her chest, adjusting a blue crystal embedded just below her neck—a sweet, thoughtful gift from Brad that accessorized her beautiful body, one with no limits. She looked around her apartment expectantly, watching the ooze—her body—slowly creep forward, climbing along the furniture and scaling the walls.

Her apartment had become somewhat barren. She had assimilated all of her appliances that mattered; though it would probably raise issues with the owner of the building, it was simply more convenient to have everything on immediate hand. Besides that, the dingy appliances were much more efficient when they were under her control—practically space-age advancements. And she never had to worry about cleaning her stove again.

Still, there was one contraption she had scoped out in the meantime. She glanced down, the box she had brought in drifting in front of her along calculated, gentle waves of flowing mercurial ooze. She tensed her silver fingers; they flattened, fusing together, lengthening into a sword-like appendage.

"Hup!"

With an enthusiastic, dangerous, and perhaps overly dramatic swing of her bladed arm, she made a precise cut at the packing tape; a couple more slashes followed, and the packing box disassembled in front of her.

Nestled in a bed of packing peanuts, ridged cardboard, and punctured bubble wrap was the object of her latest fixation. It was a custom made machine, moulded for a woman's pleasure for whatever form it may take. A pink vibrator with a pronounced, ridged head. It was enormous...

...Well, size wasn't a problem for Nikki; Brad was always pretty well-endowed, so she was used to taking a pounding. But with every machine and tool Nikki assimilated, its functionality improved, catered to her taste, functions enhanced, with portability and easy of access to match. She couldn't always have Brad around to fondle her, press down on her, cradle her tits and ass...

...And the potential for something like this had got her all flustered. She couldn't sit still through any of her classes, the anticipation drove her mad. And now it was here. The object of her desires...

She didn't even bother loading the batteries. She wanted self-gratification, and she wanted it now. She lowered a hand towards the shaft of the vibrator, her body leaning back as her legs spread apart; her fingers coiled excitedly around the vibrator and, her hand trembling, guided the pointed tip to her womanhood. Her labia quivered, the flaps parting on their own, beckoning the vibrator to penetrate her.

Her vaginal lips clutched the vibrator, tugging it with a frantic, excited urgency; she hardly needed to push the vibrator inside her at all, as her hungry body was eager to draw it within herself in pulsing tugs. Her hips shook as she moaned, her bubble ass oozing along the floor as she relaxed, her free hand clutching at a puddle of the ooze.

And then all of a sudden, her eyes lit up as an electric sensation coursed through her entire body—her entire body tingled, a powerful buzz tearing through her entire body. It initially concentrated in her lower body, but she could feel the vibrator liquidate inside of her as her hungry vagina swallowed the shaft deeper and deeper inside of her.

"A-ah!~" She moaned, rocking her hips as she presented herself, her fingers brushing against her loins; mercurial ooze dribbled from her labia, squirting like she was cumming herself over and over. Her labia closed around the vibrator entirely, sealing up and enclosing the vibrator inside of her; the visible bulge persisted for but a second, but she could feel the vibrator melting inside of her, the buzzing sensation coursing through her body; a two-foot tongue lolled as her eyes rolled over from pleasure, licking her lips as the buzzing subsided, settling in her core.

Without missing a beat, she flexed her arm, her forearm smoothing out, then rippling as ridges formed into a single, bulbous mass; as electricity coursed through her machine-like body, her sex toy arm buzzed with anticipation. Her arm boneless coiled around her leg, the tickling sensation buzzing along the insides of her thighs; her entire lower body felt like one big erogenous sex zone, and she was drunk off the pleasure.

As the dilgo plunged itself into her yearning womanhood, her entire body tensed up, before relaxed as she thrusted her arm into herself over and over, her body wobbling and bouncing with each thrust. She could feel her arm extending further inside of herself as her insides reformed, shifting into muscles that hungrily clenched at her arm. The sexual energy that pingponged through her body only accumulated, her body rippling, streaks of ooze sliding down her smooth skin as she sunk deeper and deeper into the puzzle. As her arm grew inside, thrusting up to her chest as it penetrated her, a curious, horny idea rose to her frazzled mind.

Her twintails lashed out, their tips plastering across the ceiling as they spread, firmly adhering to the ceiling. They tensed up, pulling her above the ground as her lithe feet dangled above the ground, trickles of ooze dribbling down her smooth, naked form. Her arms elongated towards the ground, collecting some of the mercurial ooze that collected along the ground; it swirled in a circle as if being moulded into a clay vase.

The ooze travelled upwards, narrowing to a point aimed squarely at Nikki's labia; its ridges bubbled outwards once more, again taking on a form of a vibrator... except this time, it was enormous, the size of a lamp! Standing at least four feet tall with a foot of girth at its thickest width, Nikki scrunched her toes in anticipation as she spread her legs, her twintails extending to lower herself, her vagina a gaping hole aching to be filled!

With a wet schlep, she lowered herself onto the superdildo, her chest bouncing at the dual sensations of penetrating and being penetrated; her strong hair tendrils rhythmically lifted and lowered her like she was performing chinup reps, her legs spread eagle as she cried out, moaning in ecstasy as the shaft reached to her chest over and over! She couldn't stop herself from cumming over and over, mercurial ooze dripping from her breasts, her vagina... her tongue lolled, growing to a length of two feet as it twisted around her protruding, erect nipples.

"Ah, ah, o-oh God yes!~" She cried out, her entire body tingling as a climax rode through her from head to toe. As she rocked her body over and over, she gave herself to the pleasures of her alien body. She never wanted this feeling to end.

Before, she would've thought better about indulging her alien pleasures, but nowadays everything came so naturally. She had acclimated to her new powers, and come to grow fond of her abilities. Now, she couldn't imagine ever living without them. She wanted to live without shame, without reservation, and her fantasies had went to strange places as she looked for ways to experiment with her new, limitless body.

And with every lusty gasp she let out, every speckle of ooze that splattered to the floor and walls, she smiled to herself, blessing her lucky stars that she had stumbled on such a life-changing artefact. Her life had changed irrevocably, and there was no way she'd ever go back to the way things were before...

At an unknown location, in a dimly lit office, a conversation was taking place during the dead of night. The glow of computer monitors carried through clouds of cigarette smoke. The air was heavy with tension and tobacco.

"Did you find it?" A gruff voice, sitting at the head of a mahogany desk, muttered. He had his back to the door, staring upwards at a projector screen—it displayed a map of the continental United States.

"We've searched the campus, but there was nothing that tracked." A woman in shades folded her arms, her head tilted downwards.

"We did find meteor fragments, but... nothing particularly useful. Just a broken shell." The man standing next to him slumped his shoulders.

"I don't care about the shell. I care about what was inside the shell." The man at the front swivelled to turn towards them; he buried the business end of a cigar into an ashtray.

He had the air of a military man about him, his chest bespeckled with an assortment of fancy medals. His hair was grey, prepared in a neat buzzcut; his shoulders were almost as wide as his desk himself.

Light reflected off of his ornate nametag.

Gen. Gregory Stroud

"Agent T. Agent B." Stroud idly tapped some of his medals. "We're standing on top of the biggest discovery mankind has, and may ever witness, and it'd be really awkward for me to march back to the labs and tell the boys to sit on their asses. Do you understand the importance of this assignment?"

"Crystal clear, sir." Agent B nodded. "We've been thorough."

"Thorough? I've read the reports. You could've rounded up every student into one room and interviewed them one-by-one. But you didn't." Stroud scowled. "If the taxpayers knew their money was going towards such half-assed investigating-"

"We didn't have to," Agent T raised a finger. "We found fingerprints on the pieces."

"...And who do they belong to?" Stroud tilted his head, folding his arms expectantly.

"We questioned Professor Howard Riviera; his testimony indicated he examined the meteor fragments with his own hands..." Agent T began, glancing at Agent B expectantly.

"...But he was wearing gloves. They didn't belong to him." Agent B pointed out. "We coerced the police into providing their print database..."

"And?" Stroud leaned forward, hands lowering to the desk.

"They belong to one Nichole Armitage. A student at the school." Agent B concluded. "She's our prime suspect."

"Of course," the general tented his fingers. "Young adults tend to be a persnickety case to deal with."

"Everything to this point has been reconnaissance. We are preparing a strike squad to raid her apartment." Agent B clenched her fist. "It will be quick, precise, and under cover of night. We only require your permission to-"

"Call off the raid. Too dangerous. If our boys went in guns blazing, we don't know what we'll find on the other side." The general muttered; the twin agents glanced at each other silently, before turning back to the general.

"She knows something about the meteor we don't." Agent T clarified. "She was the first point of contact."

"So she would know the most about what we're dealing with?" Stroud's eyebrow perked up. "The labcoats would beg to differ with you field agents."

"..." The agents glanced at each other silently, before turning to face the boss once again, standing at attention.

"I sense you're confused. Don't think too hard on the course of action, merely perform as commanded." The general tapped his desk emphatically. "We pick a battle of our own choosing, at our own location. No point in flushing her out if she's been slippery enough to elude the entire force." The general chuckled to himself, reaching for a remote.

"You have a plan?" Agent T lowered his glasses.

"And that means new orders for us." Agent B followed up.

"You catch on quickly." The general clicked one of the buttons on his remote; the map lit up with various reticulars, marking key locations.

"Intel indicates that there'll be more landing sites for more meteors just like that." The general explained coolly.

"More meteors...?" Agent B blinked, watching the screen light up with concern.

"Where did this intel come from...?" Agent T tilted his head.

"That information's on a need to know basis." The general scoffed, remaining tight-lipped. "And all you need to know is the plan, as my left and right hands on the field."

The night went on, the bright illumination of the green providing the only light in the dreary office. General Stroud had a plan—a thorough plan—and Agents B and T were ever loyal to the shady organisation.
