This First Chapter is based on Kill La Kill: Final Weapon, a Hentai comic by Witchking00.

The future Chapters will be original by me, only the first chapter which lays some gorund work is based on the fan comic.

Ryuko's POV

"Why'd you call me here?" I asked.

I had been called by Satsuki to come and meet her and Mako for something.

"Ah perfect timing Ryuko." She said "Why don't you go ahead and transform."

"Huh?"

"Trust me." She said transforming herself.

"Alright." I said focusing "Let's do this!"

I felt my outfit start to change wrapping around me and pulling tightly in various places.

So…tight.

"Ha…" I panted as the transformation stopped.

"So what's the story?"

"You see we've finished analyzing Senketsu." Satsuki explained "There is still some dormant potential which you've yet to unlock…a weapon…a weapon to surpass even your scissor sword."

"Wow that's amazing!" Mako cheered.

"Is this true, well what are we waiting for, how do we unlock it?" I asked.

"Senketsu was created to fight Ragyo and the Bio-Fibers, but that potential has not been awoken yet, and there is only one way to get it out."

Satsuki started scratching the area around her crotch.

"Hmm?"

"Ha…ha…" she panted "Here it comes…"

The front of her uniform started bulging.

"Three Star Uniform Upgrade: Bio Cock!"

A huge thick white cock erupted from the front of her uniform, it was impossibly long and discolored, it was pure white along the length bit the tip was a navy blue color.

"What the fuck?!" I yelled "How the hell is you growing a cock gonna help me?! And why the Hell can you even do that?!"

"Don't worry about why." She said

"Wow Satsuki has a super-giant cock!" Mako observed.

"What the hell would I even do with it?" I mumbled.

"Try sucking it and giving her a blow job." Mako nodded.

"That is a good idea." Satsuki said "Come on Ryuko we must tap into your true potential."

"Dammit." I mumbled dropping to my knees "Let's just get this over with."

I gradually leaned forward and placed my lips around the bulbous tip of Satsuki's dick. It even though it was artificial it smelled like musk and manhood. I started swirling my tongue and working more of the penis into my throat.

God it's huge…there's no way it's all gonna fit.

"Oh Ryuko." Satsuki moaned "This feels wonderful."

"What I want to know is how the fuck this is supposed to unlock my true potential?" I growled.

"Your father was a pervert, reason leads us to this being the logical progression."

Oh fuck this…but I suppose it can't hurt to try.

I started bobbing my head faster and faster, Satsuki's Bio-cock was already starting to leak precum.

"I feel so good." I mumbled "My body is so warm."

"Yes more Ryuko more!" Satsuki begged putting a hand on the back of my head and forcing me to deep throat her cock.

I started moving my neck faster and faster, making the warmth in my body even more intense.

I've never felt like this before, it feel so good.

"Oh I can feel it!" Satsuki yelled forcing my head to the stump of her foot long "Get ready Ryuko, no matter what you must swallow every last drop of the Bio-Cock's cum!"

"MHMP!" I moaned against her girth.

I'm so hot…I need…I need this!

"Oh…oh…" Satsuki moaned "I'm…I'm…OHHHH I'M CUMMING!"

My mouth start filling with a salty fluid, the heat in my body only seemed to increase as I drank more and more of Satsuki's jizz, it filled up every inch of my mouth, coated down my throat and even leaked out my nose.

"Uhh…" I moaned as I let Satsuki pull her huge cock out of my throat "I…I feel so strange?"

"That's likely the semen melding with your body." Satsuki said.

"Uh…uh…" I felt my breathing grow uneven "Oh…OH GOD….OHHHHH!"

My whole body erupted in an intense wave of pleasure.

"What's happening?!" I screamed as I felt my skin tingling.

The heat first focused on my chest, the heat felt like it was growing. Senketsu felt tight as I looked down.

"OH!" I moaned as I noticed my breasts were ballooning larger in size, up to watermelon like proportions.

"HAA!" I gasped as the heat shifted to my rear and I felt my ass start to jiggle and pack on a few pounds.

"Oh…ho…" I panted as the heat calmed a small amount.

"Ryuko are you alright?" Satsuki asked.

"Huh…" I groaned rubbing my head "That was intense WAH!"

I screamed as I looked down at my body "What the hell happened to me, my tits and ass are huge!"

My body was all engorged and plump, I had goen from a fairly modest figure to a huge curvasous form. My tits stodd off my chest, they were bigger than watermelons, and even though I was sitting down I felt tall because my ass had gotten so huge.

"Holy Wow!" Mako yelled "Ryuko got sexy!"

That would imply I wasn't attractive before…

"OHH!" I suddenly gasped as a strange sensation pumped through my veins "My body, it's burning up!"

My pussy tingled and leaked out juices.

"I feel so good!" I moaned rubbing my clit.

I couldn't stop myself from grabbing one of my fat tits and pinching my nipple as I started to finger myself in front of Satsuki and Mako.

"Oh...AHHH!" I moaned as I orgasmed in front of them "Still…not…enough!"

I kept rubbing myself, unable to control my arousal.

"The unlocking has caused her body to become unstable!" Satsuki yelled.

"Erotic Mode!"

Satsuki suddenly shed her clothing, everything but her leggings and gloves.

"We have to calm her quickly." She said "Mako equip the uniform I gave you."

"Anything to help Ryuko!" Mako said suddenly changing and being half naked.

"What the hell is with you two?!" I snapped.

"HAAA!" I gasped as Satsuki suddenly placed her lips around one of my nipples and started sucking as she teased my folds.

"It's alright Ryuko, I'll help you relax."

"Stop it!" I groaned as Mako flicked her tongue over my other nipple "They're too sensitive, I'm gonna explode!"

My breasts jiggled around as Mako and Satsuki aggressively sucked on them, all the while the long haired girl never stopped rubbing my pussy.

"What's happening down there." She wondered aloud.

I kept on moaning as my body was ravaged by fingers and tongues.

"I can't take it!" I yelled "I'M CUMMING!"

I felt juices squirt out but that didn't stop Satsuki from pushing me onto my back and shoving her ass in my face as she examined my vag.

"MMMM!" I mumbled latching my mouth to her pussy.

"RYUKO!" she gasped "S-Stop that!"

"Delicious." I said as I lapped at her hole.

As I kept licking at her I felt my own clit pulsing with the need for stimulation.

"I think I get it!" Satsuki yelled summoning her penis "I know what to do!"

She had me sit up and placed her thick cock in between my tits.

"First thing we have to do it stimulate those massive breasts of yours." She said thrusting her hips and pushing her cock into my cleavage.

"It's a little rough, give me a little spit for lube." She said still stroking her dick.

"PTOO!" I spit and drooled into my tits to make them slick and allow Satsuki better access.

I held my tits up, gradually pushing them against her chest.

They're so big and soft…this feels really good.

"That's it." Satsuki groaned "Jerk me off with those big boobs of yours."

I dug my fingers into my huge tits and started to bounce them faster.

"Yes that's perfect." Satsuki moaned "Just a little bit more."

I pushed my breasts against her legs, my hard nipples digging into her thighs.

"HERE IT COMES!" She screamed "Squeeze!"

I smashed my tits down roughly and Satsuki hissed.

"YESSS!" she moaned as her cock twitched and started firing off ropes of creamy spunk.

"Ohh." I moaned as my breasts were covered "My chest feel so good."

I couldn't help myself from licking up some of the cum.

It tastes so salty…yet sweet…I want more.

"There's still more to do!" Satsuki called out "Mako use your dick too."

"Bio-Cock Summon!"

Mako suddenly sprouted a cock just like Satsuki and walked around to my front.

"I will stimulate from the rear." Satsuki said rubbing the tip of her cock against my pussy.

"OH!" I groaned as I felt her length pushing into my fleshy walls "It's so big…it's in so deep!"

Satsuki immediately grabbed my hips and started thrusting. My ass clapped around as my body was shaken back and forth, my huge tits slapped around and even smashed against my face.

"Not so Hard!" I begged.

"You must take all of it!" Satsuki commanded thrusting even faster "Mako!"

"Just relax and enjoy it." Mako said pushing her cock through my lips and into my throat.

"GAH!" I gagged as it pressed against the back of my mouth unexpectedly.

I moaned as my body was bounced around as Mako and Satsuki pounded me in different directions. Satsuki was practically balls deep in my pussy and Mako was grabbing my hair and forcing her cock deep down into my throat, all the while my ass was shaking and my tits were slapping around, stimulating me even more.

"OHHH!" I moaned against Mako's cock as I felt my internal walls shifting and my body getting rocked by an orgasm.

"Ryuko it's so tight!" Satsuki moaned.

"HAAAA!" Mako gasped suddenly cumming in my mouth and forcing more jizz into my stomach.

"RYUKOOOOO!" Satsuki moaned as she started to release inside of me.

"AHHHHH!" I screamed in ecstasy.

I felt the heat coming back, my body was doing something again.

"Oh…Oh…OHHHHH!" I moaned as the heat concentrated in my crotch "OOOOHHHHHH!"

I clitoris pulsed and suddenly got longer and thicker.

"No…no I can't!" I moaned as it wiggled higher and higher.

"I'm growing a cock?!" I yelled.

The thick genital swayed slightly as it passed a foot and a half long, but still stood tall in a raging erection.

"It's enormous." Satsuki marveled.

"Ha…ha…ha…" I panted as I came down off the high of growing a whole new body part.

"This is a weapon?" I growled.

I looked up, glared at Satsuki and licked my lips "You're gonna pay."

So this is my next Story, it's in Kill La Kill, it's what the readers voted for to take the place of the WBTS story. This first chapter was based on the Comic Kill La Kill Final Weapon by Witchking00 (Just google it if you'd like to see it.) I tried to add my own bits in here and there to make it my own in some way, the next chapters will be original and by me. Speaking of witch this will be shorter than my other stories, this one will only be 4 chapters sorry Kill La Kill is a little short.

After I finish this story I'll start a new one on a franchise of my choosing, and then a vote once that one finishes and so on and so forth.

Till Next Time!
