Comm48: Space Slug Broodmother Samus

[Contains titslug transformation, queer romance, corruption, mind alteration, and identity death]

The last Metroid is in captivity. The galaxy is at peace.

And that statement remained true for untold ages. No, seriously!

The famed bounty hunter Samus Aran had eliminated the space pirates, dealt with every form of X Parasite, scoured every last trace of Ridley, and defeated all sorts of other threats in her time. But now… the galaxy no longer needed her skills; and Samus was at a loss for where to go from there.

Eventually though, she decided to try her hand at ecological studies. Years of exploring strange places and interacting with new creatures had piqued her interest, and she figured she could help repair ecosystems damaged by invasive species like the metroids. What’s more, her friend and romantic interest Doctor Amber was the project lead at Star Base DS99 - a fauna rehabilitation colony - who had invited her to join her team. As such, she chose to settle down with Amber to a life of animal care.

Weeks of training flew by, and before she knew it, Samus was ready to help in her first big test.

—

In the center of the cavernous space station, Samus and Doctor Amber were preparing for a big experiment. DS99 featured an impressively large self-contained biosphere, complete with precise climate control and day/night cycles. Massive alien trees towered over the lush greenery on the forest floor, and various fauna could be heard making their characteristic calls. The two women, though, were on a slightly elevated platform which housed testing and observational equipment.

“Are you sure this is necessary?” The former bounty hunter winced as her crush placed a simple, white pill in a tiny cup in front of her.

“Yes! This is the only way we’ll know if our repaired DNA will be compatible with the bodies of real subjects.” Amber affirmed her hesitant friend. With her light brown hair tied in a bun, simple spectacles on her freckled face, and a long lab coat over her rather small, lean figure, she was ready to commence the experiment.

“...By turning me into a giant slug?”

“By temporarily turning you into a critically endangered Lenosean Titslug!” Amber clarified with perhaps a bit too much enthusiasm. “Remember, if the DNA isn’t properly repaired, your human DNA will remain dominant in your body and you won’t undergo any changes. If the DNA is properly repaired, your body will transform into that of a Lenosean Titslug for no more than three hours before your immune system begins to flush the foreign DNA from your system and restore you to your original form.”

“And why can’t you just test this on an actual titslug?” Samus folded her arms and grimaced.

“Because it could be dangerous to a real one - but only a real one - if the DNA hasn’t been sequenced just right.”

Staring at the pill for a moment, Samus took a deep breath and cast aside her doubts; she trusted Amber, and wouldn’t even consider such a transformation if it were anyone but her asking. “Alright…” And with that, she threw back the pill into her mouth and took a swig of water to easily down it.

“Oh, um… I was going to suggest removing your clothes first, but…”

Normally, Samus had no qualms with being seen naked; she just didn’t care. With Amber, though, she realised she might actually be a bit self conscious of what she thought of her. Hiding her hesitancy, she pulled her tight tank top up and over her head to reveal that three new pairs of nipples had already appeared on her muscular midsection! Moreover, her bra felt a size or two tighter than it had just moments prior.

“It’s working!” Amber’s beautiful face lit up - and simultaneously blushed a deep red at the sight of the tall, strong lady undressing before her.

Samus then tried to unhook her bra behind her back, but found her fingers were rapidly losing their motor control. When she moved her hands back in front of her, she was greeted by the sight of her digits receding and her arms shrinking away! Her sight, though, was getting spotty and out of focus, making it difficult to watch her two upper limbs melt away into her torso.

“What’s h-happening? Nnng…” She moaned, her voice subtly breaking as her vocal chords were reconfigured. A pressure had built in her skull behind her eyes, and her vision was just a jumbled, inexplicable mess. “Your briefing didn’t say anything about these th-things being blind! I can’t see a d-damn thing… Nothing that makes sense, at least.” Samus’ deep, alluring feminine voice was growing higher and squeakier with each word.

“Ooh! Please describe what you’re seeing and feeling!” Amber snapped out of admiring Samus’ growing rows of breasts so she could grab a clipboard and take some notes.

“C-colour everywhere… So much, too much colour… I don’t unders-stand!”

“Oooooh! You must be seeing new colours! Lenosean Titslugs have twelve types of cones in their eyes, but humans only have three - red, blue, and green. I’m curious, what’s it like?”

“I… I…! H-how do I describe colours I’ve never experienced before? There’s one that’s like… red? Red, except if it was both black and white at the same time… Nnng, it’s hard to comprehend what I’m s-seeing…” Samus squirmed a little, resulting in a bit of a squelching sound. Her skin was forming a layer of slime all over as her body shifted to a slightly bluer hue.

Now, the transforming woman’s eyes were bulging out of their sockets, stretching and growing into flexible eyestalks! Simultaneously, a similar pair of sensory stalks were forming on either side of her jaw - stalks which Samus could smell through!

“Your upper tentacles are forming, and so are your lower ones…” Amber muttered to herself as she frantically took notes. “-Oh! Sorry, your visual stalks are the upper tentacles and your olfactory ones are the lower tentacles.”

It took a few seconds for Samus to form a response in her slowing mind. “I know, I remember from your briefing. Nnng…”

“Slower speech… Slime production… Swelling primary breasts… Additional breasts coming in nicely…”

“Nnng, t-tight… So…! Tight!!” Samus instinctively tried to reach for her waist to undo her belt, but she no longer had arms to speak of. Though she might have had difficulty seeing below her ever expanding mammaries before, her upper tentacles were able to peer over her slimy boobs to her strained cargo trousers below; her hips had widened and there were a number of symmetrical lumps on either leg forming tears in her snug clothing. What’s more, her legs were rapidly losing rigidity, causing her to wobble and fall onto her increasingly plump rear end.

“Oh, um… Would you l-like some help getting out of your clothes?” Amber blushed rather gayly again at the thought of removing Samus’ trousers.

“...” Samus took a moment to process what was said to her. “Y-yesh, geth me outh of here!” Speaking was growing difficult as her tongue lengthened to the point where it no longer fit entirely in her mouth!

Setting aside her clipboard - and her gay hesitance - Amber knelt down and slid off Samus’ utilitarian knee boots to find that her feet were no more than slimy little tails wiggling adorably. Before she could help with her trousers though, the rest of Samus’ clothes burst from the strain, sending shreds and threads of fabric flying all around her. Now plain to see were the sluggy little tits growing down the front of both legs!

“Wow, this transformation is happening quicker than anticipated…” Amber remarked, getting back to her feet so she could grab her clipboard and compose herself once more.

Now that there weren’t any trousers to interfere, Samus’ legs wasted no time pressing together and fusing into one big extension of her titslug torso. Light blue colouration had permeated the skin of her face and long, tiddy-covered tummy, while her backside became a darker blue splotched with little sparkles. The former bounty hunter’s skeletal structure was greatly diminished now, allowing her to writhe and twist to otherwise impossible degrees.

And just like that, Samus’ body was that of a perfect Lenosean Titslug! Her long, gooey, limbless form featured rows and rows of soft tiddies of descending size - the heftiest of which being larger than her head! The four tentacles on her face wormed around aimlessly at a pace that would make molasses look like a raging waterfall, and her footlong tongue dripped more of her viscous slime. “I… can’th… think…! Tho… Thlow…”

“Already slowing down mentally, hmm? Alright, tell me before it’s too late what you’re thinking about!” Amber waited patiently as her words sunk into the big, dopey slug woman.

“...Amber…love…” Samus’ upper tentacles found the visage of her love interest and would not move to look at anything else.

“Recognition of what she sees… and potential spike in libido as expected.” The true meaning behind Samus’ last humanly words were lost on the oblivious scientist.

Samus’ perception of reality was being moulded like putty by her new sluggy DNA. The urge to survive and reproduce was swelling within her now that she belonged to a species of perpetually endangered space slugs.

‘Big… beautiful… boobs…’ The titslug’s mind was flooded by the desire to find another of its kind with huge mammaries. Locating a mate who was suitably sizable was always a challenge for a species with such low numbers, so their evolution led to nearly all-consuming reproductive instincts. With the lack of other present titslugs, though, Samus made do with Amber’s rather shapely figure before her. ‘Boobs… Amber…? Love…’

“Alright, S-Sammy…” The researcher hesitated. The titslug’s lack of response made her worriedness evaporate. “I’ve always wanted to call you that~” She blushed, looking into Samus’ upper tentacles. “I just didn’t know if it’d be too familiar or cutesy for you… Maybe I should ask you when you turn back? Maybe I should ask you out when you turn back… Ohhh, I hope you’re into women like I am!”

The titslug gave no response beyond her continued squelchy writhing and idle movement of her tongue and tentacles.

“A-anyway! Uh, l-lets start some of the tests…” Amber inputted some commands to her computer terminal, prompting a smooth metal orb to emerge from the floor and hover about two meters in the air. After a moment, it projected the holographic image of a metroid over itself and began playing recorded screeches typical of the notoriously hostile species.

Samus reacted to the sounds in just under two seconds - lightning fast for a Lenosean Titslug - peeling her eyestalks away from Amber to face the illusion behind her.

“Come on Sammy, you can do it!” The human woman whispered under her breath.

When it registered in her sluggish mind what she was perceiving, Samus sucked in as much air as she could, inflating herself to be as large as possible. ‘Standing’ such that as many of her breasts were exposed as possible, the former human wriggled her body and bounced her voluptuous tiddies as fast as she could!

‘Protect…! Family…! Protect…! Amber…!’ Samus’ strong survivalist instincts kicked in, directing her to focus on protecting her pack. Regardless of whether it was Samus’ humanly fondness for the doctor, or simply her alluringly substantial chest size, Amber had been cemented in her mind as a packmate to be defended at all costs. She positioned herself between the pseudo metroid and Amber, using her inflated body to shelter her from sight.

“Excellent!” Amber cheered, quickly commanding the orb to cease its projections and return to its dock. Hastily taking more notes, she muttered to herself. “Normal reaction time… Response to threat typical of a Lenosean Titslug… Normal anatomical functions…”

About thirty seconds after the projection ceased, Samus realised the threat was gone and allowed herself to exhale. Returning to her normal size and stature with most breasts resting on the ground, Samus proudly turned back to Amber after having scared away the dangerous predator. ‘Gone…! Monster… gone…!’

“...behaviours befitting a-! H-hey!” Amber was interrupted by a few slimy pairs of breasts pressing against her side. “I know you’re happy, Sammy, b-but I need to-! I’ve got to-!!” Quickly realising she was fighting a losing battle, the researcher set aside her clipboard and took a deep breath. “I guess I can take notes later… For now though, are you hungry?”

Unable to comprehend human language anymore, Samus simply continued to ‘hug’ Amber, blissfully unaware of the treat she was about to receive. By the time the smell of fresh fruit registered in Samus’ mind, Amber was already dangling a bunch of Lenosean bananas in front of her face! Her lower tentacles needily rubbed against the bananas, taking in their delicious scent while her tongue coiled around them as swiftly as possible.

“Hee hee hee, that got your attention~” The human woman teased, letting go so that Samus could take the snack for herself. “Now, let’s see if you do what I think you’ll do…”

Wasting none of her precious time, the titslug dropped the bananas on the floor and crawled over them. With all of her body weight pressing down, Samus wiggled and squished the soft fruit with her hefty tits. Squashed banana mush oozed out from their flattened peels all over the ground and her soft, goo-coated skin. Once she was confident her meal was suitably smooshed, Samus backed up, leaned down, and vacuumed up the Lenosean banana smoothie despite her big awkward tongue occasionally getting in the way. ‘Yummy…! Food…!!’

“Hee hee~” Now that Samus was preoccupied with her snack, Amber returned to jotting down notes - but then stopped. “I wonder what she’d say if I took her out to dinner tonight… ‘as a thank you for the help’? I don’t know… Ohhh, maybe I should just be more forward. Hell, I’ve already seen her naked, what’s asking her out by comparison?”

However, there would be no casual dinner dates that evening. Unbeknownst to Amber or herself, Samus’ Chozo genes had been gradually bonding to the foreign titslug DNA and permanently integrating it into her body! The unforeseen interaction resulted in the mutation and conversion of her lingering human DNA into that of a whole new species: a Chozolenosean Titslug! This new breed was identical to Lenosean Titslugs in all but one key way - she could infect other beings with her mutated DNA and transform them into yet more Chosolenosean Titslugs!

With such dominant biological life overtaking her very core, the former bounty hunter was overcome by a new instinct: convert and assimilate. Once she’d had enough of her mushed food, Samus - now Sammy the Titslug - returned her sights to Amber with a determined glint in her eyestalks. ‘Amber… Mate… Love…!~’

“Hmm? Are you not going to finish your bananas?” The researcher watched as her test subject slowly wriggled closer, until finally Sammy was upon her. “Do you want another hug?”

Sammy practically tried to climb up the human woman’s side, making her lose balance and gently tumble to the ground. Before Amber could get back to her feet, though, she found the tail end of Samus’ sluggy body wrapped around her leg!

“Uhhh, S-Sammy? What are you-?”

With surprising speed (for a titslug at least), Sammy coiled her body around that of her friend so she could smother her in loving boob presses. Being nourished, content, and aroused, the Chozolenosean Titslug displayed a behaviour rarely exhibited to non-titslugs; she began to purr!

“Oh gosh! Oh, um, I-!! Ummm!?” Doctor Amber’s face was rosier than a Lenosean tomato as she laid on the ground wrapped in a slimy, living blanket. “S-S-Samus??”

‘Make… Amber… like… me…!~’ Sammy lustily leaned forward to slide her long tongue into Amber’s mouth for a long, slimy French kiss! Her corruptive goo was passed on to Amber, who could do nothing but enjoy the love and intimacy from her friend-turned-slug.

“Mmmm!! Mm-mmmm…! Nnng, Mmmm…” Feeling the slime ooze down her throat, the soon-to-be-former human moaned in shock and - to her shame - arousal. The sensation of gooey slug girl juices filling her up and converting her from the inside out felt shockingly pleasant, as the first thing it corrupted was her drive to breed and convert people into titslugs! ‘Y-yes! Make me… just like you… I need it, I need you! I need-!! Nnng, breed me, Sammy!!’

As new breasts formed all over her body, Amber was thankfully spared the resistance from her tight clothing as it was quickly dissolved by Sammy’s slippery goop. She felt the inexplicable sensation of her dozens of pairs of breasts squishing up against and sliding between those of her sluggy mate. The researcher’s lithe limbs melted away and merged into her body as her pores began to produce slime of her own - slime that also acted as an aphrodisiac.

‘Yes! M-make me one of y-you! One of… us…!’ Amber’s sexuality warped to fit that of a Chozolenosean Titslug as her fantasies shifted away from featuring a tall, strong, buff human woman and towards a soft, slippery, squishy slug girl! And she knew she had the power to make everyone perfectly soft, slippery, squishy, and sluggy! ‘One…! Of…! Us…!’

Finally, Amber’s face caught up to the rest of her altered body and corrupted mind: her jaw sprouted cute little lower tentacles; her tongue slowly coiled around Sammy’s as it grew exceptionally long; and her eyes sprouted into long upper tentacles that remained fixed on Sammy’s alluring visage. There were now two fully formed, infectious titslugs aboard DS99!

Three words repeated in the minds of both former humans as their loving embrace became a horny mating press. ‘One…! Of…! Us…!!!’

Sammy’s slime blended with Amber’s as their slow, intimate wriggling stimulated their many tender nipples and fulfilled their need for togetherness. When they finally reached the peak of pleasure, their sluggish climaxes lasted for nearly an hour! A long, slow flood of hormones and mind-bending bliss was rewarded to them for acting to perpetuate their endangered species.

—

Hours later, when they’d physically and mentally recuperated from all that exertion, the two Chozolenosean Titslugs once again felt the drive to expand their pack and protect their family.

‘More…! Make… More…!!’

‘Follow… Sammy…! More… Like… Us…!!’

“Hey, what the-!?” Another researcher finally appeared after Amber and Samus failed to return to the station’s meeting room, only to find two suspiciously familiar slugs at their last known location. “Is this Doctor Amber’s experiment? And where is she?”

Unaware of the peril she was getting herself into, the fresh researcher wandered too close to the titslugs and found herself coiled in a pair of beautiful alien women before she knew what happened. Her fate - and that of the entire space station - was sealed.
