Wii Fit Assimilation [Semi-Twinning, rubber TG TF]

Daisy and Samus had just finished battling in a one-on-one tournament, capping off the final round of the evening. The pair had become fast friends after Daisy joined the roster of Smash fighters, enjoying fighting together, fighting against each other, and especially bonding between matches.

On their way to the women’s hot spring, Daisy spotted Wii Fit Trainer lingering in the corridors under the arena. Her standard, light blue tank top and dark grey leggings hugged her perfect, almost artificial figure. Neatly tied back in a tail, her soft grey hair stuck together so flawlessly that it almost seemed like it wasn't really hair at all. But what else would it be?

“Hiya Fitty! What are you up to?” Daisy greeted cheerfully.

The lean, uncanny woman turned her head to face the ladies walking towards her. Her dull grey eyes seemingly pierced Samus' very soul, sending a shiver coursing through her entire being. She was the galaxy's greatest bounty hunter, eradicator of the Metroids and slayer of beasts beyond imagination without so much as a flinch; and here she was, chilled at the sight of a fitness instructor. Samus didn't know why, but she always had a bad feeling whenever she was near her.

"Hello Daisy, hello Samus," Wii Fit Trainer replied, almost robotically.

"You should join us in the hot spring, Fitty!"

Samus' heart sank. 'Why,' she thought, 'would Daisy invite her? Doesn't she see how creepy she is?'

The Trainer shook her head. "I'm afraid I have other things to do."

"Aww, c'mon! It'll be relaxing! Giving your mind time off is as important as giving your muscles time off. And besiiides," Daisy eagerly drew out the word, "you're the only fighter here I haven't chatted with before!"

Before Wii Fit Trainer - or Samus, for that matter - could so much as protest, Daisy had practically dragged the enigmatic instructor with them, talking nonstop until reaching the locker room.

---

Samus and Daisy slowly stepped into the steamy bath, feeling rejuvenating warmth mend their spirits. Samus envied Daisy's confidence: though she could challenge beings from seemingly the depths of hell without batting an eye, Samus still felt nervous revealing her naked body to others - especially women who she was attracted to like Daisy. As such, she decided to slip into her navy blue bikini for the hot spring.

The princess, on the other hand, was as much in her element here as she was in any other situation. Daisy unwaveringly strutted out to the spring stark naked, just as confidently as ever. Samus felt a wet spot appear in her bikini bottoms before even stepping into the water.

Daisy's cute little breasts still bounced with each graceful step she took. Her toned, muscular legs were complimented by impressive, shapely glutes. And her pussy! Her pussy  was prettier than any flower Samus had ever seen before. Subtle twin scars were visible next to her outer labia, and Samus knew exactly what that meant - she herself had scars just like them.

Samus felt self-conscious about her vulva. While she was overjoyed with the results of her bottom surgery, she was still worried that her pussy wasn't as good as a cis woman's. She was afraid that someone in the hot spring might notice her scars and clock her as trans. Yet here was Daisy, waltzing in with identical scars, seemingly possessing all the confidence in the world. Samus couldn't help but envy her just a bit.

"You like what you see, Sammy?" Daisy winked, stuck her tongue out with a playful smile, and flashed an upside down peace sign over her pussy lips with her index and middle fingers.

"I-! Wha- um, uh-!?" Samus's face turned beet red as she realised she'd been staring. "I'm sorry, I was sort of… lost in thought."

"Hee hee, I'm only teasing you, don't worry about it."

Together, they stepped into the steamy pool of water, sitting down on one of the submerged steps.

"I, um… well, Daisy, I just… you see, I… um…" Samus muttered before trailing off.

"If you're feeling bad about staring, don't be. I promise it's alright," Daisy said sincerely.

"It's not… Well, it is about that, sort of. Fuck, I just have to spit it out. Daisy, I'm trans." Samus sighed.

"YOOOOO, SAME!" Daisy yelled elatedly. "Ohhh, wait, so that's why you were staring..."

Samus nodded. "That's also why I'm wearing this. I have scars just like yours, and I'm too insecure to let them show. I don't want to be seen as anything other than one of the girls."

"Sammy, if anyone so much as implies you're anything but one of the girls, I will bury them." Daisy assured her.

"Thanks Daisy, I appreciate it!" Samus smiled. "There was something else I wanted to tell you, though…" Samus went quiet, realising she had almost committed to confessing her feelings for Daisy.

At that moment, Wii Fit Trainer emerged from the locker room, still wearing her leggings and tank top.

"I'll tell you later," Samus whispered.

"Awww, aren't you coming in, Fitty?" Daisy asked.

"I am," is all she said in response. The trainer then stepped into the spring, fully clothed.

"Uhhh, Fitty, you're usually supposed to take your clothes off before coming in here," Daisy said, her voice steeped in confusion.

"What are you talking about, I am naked, aren't I? This is my skin…" Wii Fit Trainer ran her hands over her breasts, down her tummy, and onto her thighs.

Samus and Daisy exchanged uncertain glances, then returned their eyes to Trainer.

"Ugh, I've done it again, haven't I?" Wii Fit Trainer asked rhetorically. "And I was doing so well at fitting in this time. Heh, fitting in.” Wii Fit Trainer chuckled, showing emotion for the first time. ”Oh well, I guess play time's over."

Wading through the water towards the two women, Wii Fit Trainer wore a sinister smirk on her face.

"Don't hurt her," Samus ordered, standing up to shield Daisy behind her.

"Hurt her? Don't make me laugh. You'll both be screaming my name in ecstasy soon enough~"

"So you do have a name." Samus glared at the approaching threat.

"Sammy, don't get hurt trying to protect me! Please!" Daisy shifted from behind Samus to beside her again.

Samus quickly glanced at her friend, then returned her gaze back to Wii-

"Boo~" The trainer had seemingly warped three metres, now standing right in front of her.

"ACK-" Samus lost her balance and slid backwards, hitting her head on the side of the pool. She saw stars bursting in her line of sight, dancing around Wii Fit Trainer as she placed a hand on Daisy's shoulder.

Colour drained from Daisy's shoulder, then her upper arm and chest, then the rest of her body. She was becoming the same pale tone as the fighter looming over her.

"Dais- urk!" Samus was too stunned - both mentally and physically - to do much of anything. All she could do was watch in horror as her crush seemingly had her humanity sucked out of her.

Daisy's brown hair sizzled as the colour burned away, leaving it an ashy grey just like Wii Fit Trainer's. Her now-grey eyes momentarily glowed a faint lilac as her horrified face took on a new expression: one of equal parts malice and amusement.

Now entirely pale like her corruptor, Daisy's skin began to reshape itself. Her nipples melted away as her tiny breasts subtly grew a couple cup sizes. Her pussy also sealed up as a burst of colour surfaced on her torso. Clothes appeared over her skin out of nowhere - no, her clothes were her skin, just as the Trainer had said. A bright orange tank top with the words "Wii Fit" written over its chest materialised, as did dark grey leggings with a matching orange waistband.

Daisy and Wii Fit Trainer somehow wore identical, uncanny smiles on different faces.

"Hi, I'm Wii Fit Daisy~" The words came from Daisy's mouth, but it was definitely Wii Fit Trainer's voice.

"What in the Chozo-Ruin FUCK!?" Samus spat, unable to trust her own perception. "What the fuck did you do to her!?"

"I've assimilated her, space brat." The original trainer taunted.

"You've possessed her!? Give her back!"

"No, I haven't possessed Daisy, I am Daisy. She is me, and I am her. Her memories, her thoughts, her feelings, her body…" Wii fit Trainer mused.

"...They all belong to me now." Wii Fit Daisy finished her counterpart's sentence.

"That's impossible!" Samus cried out in defiance.

"Hmm hmm hmm~" Wii Fit Daisy laughed with a quiet hum. "This one harbours quite the feelings for you." She held a hand to her chest as she mockingly assumed Daisy's original voice. "'Oh Sammy, show me your pussy! Press my face into it as your big, strong thighs squeeze my head so tight! Oh Sammy, hold me tight and never let go!'" The corrupted princess leaned closer, tauntingly batting her eyelids as Samus' face flushed. "'You're so dreamy, Sammy! My knight in shining armour! Cuddle me as you slide a hand into my panties, my love~'"

"Take your words out of her mouth before I take them out myself!" Samus threatened, though still too shocked and disoriented to make good on her threat.

"'Oh Sammy, I want you to put things into me, not take things out!'" The transformed woman winked, then returned her voice to that of her corruptor. "You poor, pathetic thing. Those were her words. Her thoughts belong to me now, and so, so many of them are about what she wanted you to do to her~" Daisy's glare - now using Wii Fit Trainer's eerie, piercing eyes - made Samus feel even more naked than she currently was. "We'll be together, Samus. All three of us, plus whoever else we want to join with us."

"I'll n-never join you!" Samus spat.

"That was a statement, not an invitation. You will be one of us~" Both Wii Fit ladies opened their arms and spoke in unison. "Now give me a hug~"

Samus leapt out of the spring and bolted to the locker room before they could touch her - or so she thought. Before even making it halfway to the door, Samus felt her wrists and ankles constrict in an inhumanly tight grip. Looking down, she saw greyish white hands clasped onto her, then looked over her shoulder to see something horrifically unexpected: Wii Fit Trainer and Daisy were both still standing waist-deep in water about 8 metres away, and had stretched their arms out as if they were elastic! She was lifted into the air by the stretchy arms with incredible ease, then pulled backward to her captors as their arms retracted. As she was spun to face them and placed back in the water, Samus realised her hands and feet had gone numb. The pain of their tight hands around her limbs had faded away despite the continued pressure they exerted on her body. Squirming violently, Samus looked at her hands and saw that they had been infected by the dull grey plague, and it was spreading up her arms. She could only assume that was happening to her legs too. Her vision gained a light lilac hue - presumably, her eyes were emanating a pale violet just as Daisy’s had merely minutes ago.

Her mind was almost as if it were a house dislodged from its foundation by a landslide, about to get swept away. She could feel herself losing concentration and will power by the second. Both stretchy monsters disguised as humans were grinning wickedly as they watched her futile struggle, and one thought lingered in the front of her mind: ‘I envy them.’ No matter how much she tried to push the thought aside, no matter how many times she told herself that wasn’t her thought, no matter how desperately she clung to her sense of self, she couldn’t overcome that one thought. She began to believe those three words burned into her brain. She began to actually desire joining them.

“‘Oh Sammy, you look prettier already!~’” Wii Fit Daisy said in her stolen voice.

Her captors released her from their grasp. Taken aback, Samus realised her body had stopped resisting without her conscious awareness. She tried to run, tried to shout for help, tried to move at all, but she couldn’t. She had no will power left within her transforming muscles. Her entire body below the neck was grey and lifeless. Everything felt inexplicably artificial: her pulse and heartbeat had frozen; she was no longer capable of breathing; and her body felt solid, yet flexible, throughout. What even was she? Rubber? Plastic? Memory foam? It was impossible to wrap her mind around her sensations, especially with the continued assault on her mind.

“‘Give in, Sammy~’” Wii Fit Daisy spoke, but her mouth didn’t move.

“Give in and be like us~” Wii Fit Trainer echoed, her mouth also remaining locked in a menacing smile.

No, they weren’t speaking - they were already in her mind.

“G-get out of my head! I’ll join you! Wh-what!? No, I mean I’ll never join you! Never!”

The lone lock of hair drooping into her vision had just turned grey, and her sense of colour had returned to normal. Her body began to feel odd again - especially her erogenous zones - as it was sculpted like clay into something new. Her expanding boobs seemingly merged together as her bikini top melded with her skin and reshaped itself into a navy blue Wii Fit tank top. Her nipples vanished, but their erogenous sensations didn’t - now, her entire chest was an erogenous zone, and the sensation was spreading through the rest of her body. A similar thing was happening lower on her body as her bottoms grew down her legs, fusing with her pussy and anus, sealing them off forever. Only the waistband retained their navy colour, the rest - of course - became the same dark grey leggings as those of her two counterparts. Her clitoris dissolved with the rest of her vulva, spreading its sensitivity throughout her body just as with her nipples.

There was one overwhelming sensation flooding her mind, and it was relief. Her envy had been satiated - she was just like them now. There was still a sliver of herself holding together in the depths of her brain, sickened that she was actually enjoying this.

“‘Oh my, Sammy~’” Wii Fit Daisy cooed throughout her head, echoing as every secret and personal memory was taken. “‘You looooove me~’”

“Th-those thoughts aren’t yours to- yours to…” Samus couldn’t finish her thought.

“‘Isn’t it so intimate sharing a consciousness? Feeling what each other feels? Thinking what each other thinks? We can share everything like this, Sammy! I know you want to share everything with me~’”

“Share with Daisy… n-not you…” Samus barely strung together a coherent thought of her own volition. Most of her agreed with the hive mind. She was a part of the hive mind now, after all, whether she wanted to be or not - and she was so close to admitting to herself that she truly did want to be.

Samus was abruptly pulled out of her thoughts by her physical sensations. Wii Fit Daisy had pressed her lips onto her own as she coiled her long, stretchy arms around her body several times over. Everything was pure bliss now that her entire body was a squishy, stretchy erogenous zone. But that wasn’t all - Samus now felt Wii Fit Daisy’s and Wii Fit Trainer’s bodies as if they were her own. The three of them shared not just thoughts, but physical sensations as well. The corrupted bounty hunter felt as though she were approaching three simultaneous full-body orgasms.

And then the final piece fell into place.

Wii Fit Samus quickly returned the favour, wrapping her own now-stretchy arms around Wii Fit Daisy’s torso, between and around her legs, then back up her body and around her shoulders. Wii Fit Trainer joined in, coiling her rubbery body around them both like a snake. The three of them continued to stretch and squeeze and pull on each other, tying themselves into one big orgasmic knot.

Climax hit harder for all of them than it ever had before. Every part of their bodies tensed and writhed as pleasure flowed through their bodies. Waves of orgasmic energy rippled down their long, noodly limbs to the very tips of their fingers and toes. Three voices moaned in their collective mind simultaneously, revelling in their corrupted, assimilated senses.

But the fun was only beginning. They could only imagine what four, then five, then six and seven and eight more simultaneous shared orgasms would feel like. But they couldn’t stop there. They needed more. They needed more and more people to convert into the Wii Fit Hive immediately. With great urgency, the trio set out to find as many other potential converts as they possibly could.

The End?
