WARNING! MENTIONS OF NUDITY!

Teenage Mutant Ninja Turtles

"Sugar, Spice, and a Splash of Mutagen"

Chapter 3

My Sons?

Donatello felt like he had been hit by a bus.

Eyes flitting open to reveal a hazy, white blur, the purple-banded turtle blinked his foggy vision back into focus, a low, guttural moan passing through his lips before he rolled over onto his carapace. Oh man, did he felt like shit. Like he had literally run into the street and just stood there like an idiot waiting for a bus to come by and run his ass over; his limbs tender and increasingly heavy. Would he be so stupid as to try something like that? He highly doubted it. So why on earth did he feel like someone bashed him repeatedly with a sack full of bricks?

Something didn't feel right.

Eyes narrowed perplexedly and shifting back and forth, Donatello realized that he was lying perfectly angular to the ground set beneath him. There was no elevation where his shell met the floor and it all felt rather foreign and strange. Was this why he was feeling so much pain?

Lifting himself up with aching, shaky limbs, Donnie didn't catch anything out of the ordinary until he caught sight of the lower half of his body. His legs were propped up and bent at an angle. But they weren't his legs. In fact, none of what he was looking at was his! Smooth, creamy alabaster skin. White and flawless without a trace of hair. That is, until his eyes trailed over the area between his legs, a small tuft of curly brown strands covering an area that immediately stained his cheeks a bright, crimson red.

Did he…? Was that a…? Was he a … a….

"DONNIE! DONNIEDONNIEDONNIEDONNIEDONNIE!"

The purple-banded ninja whipped his head in the direction of the screaming, his eye mask tilted and hanging over the tip of his nose. Tugging on the piece of fabric, he pulled his hand back and examined the long, slender fingers, five for each hand and much smaller than his three-fingered turtle hands.

What the hell was happening? What the fuck happened to him last night?!

"Oh God. Oh man. Oh geez." He panicked, his breaths coming out in short, quickened puffs that he tried to no avail settle down or ease. "This is all a dream. I'm dreaming right now. Yep. Totally dreaming. This isn't happening. None of this is happening, alright, Donnie? This is all just one completely horrifying, super creeptastic, freaky…"

And just like that, the words were completely stripped from his mouth, his eyes as wide as dinner plates as he stared up at a very frightened, very naked short blonde girl with striking blue eyes.

If Donatello wasn't blushing before he sure as hell was blushing now.

"D-Dude … D-Donnie?" The blonde girl stuttered, her lower lip quivering as she raised a shaky, very tiny finger in Don's direction. "I-Is that … is t-that you, bro?"

"Mikey?" Donnie's eyes widened, crawling up to his feet without so much as breaking eye contact with slender, tiny, short-haired blonde girl.

She was rather petite and had a smooth, rich complexion – save for the flecks of tiny speckled freckles sprinkled all across her rosy cheeks and the bridge of her nose. Her hair was short and layered into choppy wisps, the color a miraculous shade of pure, glistening gold. The eyes, however, are what gave it away as Don stared intently in those pools of liquid innocence; translucent and blue like an ocean preserved for many, many years.

This wasn't happening. This. Wasn't. Happening.

"I … I don't understand! How could this have happened?"

"How come we're naked? Where are our clothes?" Mikey asked, surveying his body and even going as bold as to touch his skin, smooth and distinguished like refined silk.

"Uhm, hello. We're turtles, Mikey. When have we ever worn clothes?"

The orange-banded ninja looked up at his brother with big, almost doe-like eyes, his fingers grazing over the dip of his hipbone before he quirked up his eyebrow in blatant confusion. "And how come your hair is brown and I'm blonde? You think we'd have roughly the same hair color."

"I don't know, Mike, okay!" Don practically shouted at his brother, pacing back and forth with his hands gripping both sides of his head only to draw them back when he noticed he had touched something soft.

Fingers laced in strands of silky, chocolate brown hair, Donatello realized Mikey was right and he quickly began to spiral back into panic mode. His breaths were coming out in rapid spouts of hyperventilation, limbs shaking and his eyes flicking back and forth. Oh, God what was he going to do? This didn't make any sense! How in the world did he and Mikey transform into teenage human females!? Were Leo and Raph affected as well? What about their sensei?

Sensei?

"Master Splinter!" Donatello shouted, immediately rushing toward his sensei who was still passed out on the floor just outside his lab.

His lab. Yes, it was all starting to come together again. The accident. The fire. The explosion. The mutagen.

…The mutagen. Yes, it all started to make sense. The mutagen! That must've been the main factor that turned him and his brother human. But why did it reverse the sexual characteristics? He had been tampering with it a little to achieve the desired effects to turn them all into human males so what could've gone wrong? Was it because he hadn't worked out all the kinks yet? Was it because it was retro-mutagen?

Oh, crap! The retro-mutagen! The key to turning Kirby O'Neil back into his human state—the key to giving April a normal life with her father once again. It was gone. Everything in his lab had been destroyed. Wiped out. Broken and rendered useless, never to be used ever again. And what about Timothy? The Pulverizer. He was still stuck in the lab during the result of the fire and Donnie couldn't even remember to get him out of their and save him. He was gone. Everything that had been stored in that laboratory was gone.

He felt sick; a churning mass of discomfort and anxiety all swiveled together deep within Donatello's stomach. He wanted to hurl. Wanted to curl up in a ball and just close himself off from the world. How was he going to face April? How was he going to explain this? This new body of skin and hair and girlishly long nails. First him and April weren't even of the same species. Now she had an entirely new incentive to avoid going out with him. He was a girl. With long hair, soft skin, and … and….

Eyes trailing south, Donnie felt his cheek flame at an alarmingly hot temperature as he stared at the two, plushy mounds of his soft, subtle breasts. Because it was always so cold down in the sewers, it didn't take long for the nipples to become stiff and harden, the darkened area around the nipple tightening and making his breasts more prominent. He immediately felt as though he were going to die from embarrassment, reaching over to cover the distinctively small breasts only to fall back short and blush even harder. He'd never touched female breasts before and even though they were technically his he still felt wrong for doing so.

This wasn't happening. All of this seriously was not happening.

The sound of a groan quickly snapped Donnie right out of his thoughts. Hovering over the wizened rat with Mikey kneeling next to him, they watched as their father cautiously stirred himself awake, reaching a hand to place firmly on his head. His eyes wound shut as he tried to quell the horrendous pounding.

"Itai. My head…" He moaned miserably, rubbing the soreness at the side of his temple.

Acting quickly, Donnie immediately clamped his hands over Mikey's mouth, preventing him from speaking as he tried addressing the matter as carefully as possible. After all, it wasn't every day a father got to wake up to two daughters when in reality he actually had two sons. He had to approach this situation carefully.

"Uhm, M-Master Splinter?" He placed a gentle hand on his father's shoulder, fingers twitching just in case he had to retract when his sensei sensed the unfamiliarity. "I-It's me, Dona—"

"DONNIE! WHAT! THE! FUCK!"

Head whipping back in the direction closest toward the hallway, both Donnie and Mikey watched with widened eyes as they saw two other girls come rushing into the living, fear prominent on their light-skinned faces. Like he and his brother, what Donnie had presumed to be Leo and Raph were also stripped of any clothing, their belts hanging precariously from their slender waists and curvaceous hips. With their eye masks dangling from around their necks, it was easy to tell which one was Leo and which one was Raph, Leo adorning very long, sleek black hair and Raph sporting a short mass of deep auburn tresses that framed his face. Neither looked very happy with their new appearances and Raph wasted absolutely no time in rushing toward his purple-banded brother, yanking him from his eye mask and nearly choking the confused brainiac.

"What the fuck did you do to us!?" He growled with venom lining his words. Not only were their physical appearances transformed to look more feminine, but from what Donnie could hear just by the way they talked, their voices had changed as well; the growl in Raphael's voice raised to a higher pitch that diminished the effect of his gruff, edgy undertone.

Rising to his feet, Master Splinter steadied himself on his cane before placing a hand atop of his head, shaking it carefully while trying to compose his thoughts. His head was angled downward, eyes wound shut to help him think and also to prevent him from being exposed to his very underdressed sons. This was all so new. So unexpected and strange. What on earth transpired that caused such an occurrence to happen?

"Donatello, my son," Master Splinter started, opening his eyes but not daring to look up at his intelligent son. "What happened?"

"The mutagen," Donnie explained, his eyes flicking toward his charred, smoky lab. "I knocked over a canister I had been examining last night and it got all over both Mikey and I. And when we were pulled to safety—"

"It got on both Raph and I as well," Leo interrupted, the wheels in his head starting to turn as he stared down at his hands, both fascinated and horrified at the extra-added appendages.

"So what's going to happen to us?" Mikey squeaked apprehensively, his baby blue eyes wide and fearful. "Are we going to stay like this forever?"

"You can find a cure, can't you, Donnie?" Raph asked rather quickly, grabbing hold of his brother's bare shoulders and giving his body a forceful shake. "Please tell me you can find a cure to fix, this." He released his shoulders and brought his hands down, implicating his newfound feminine features that made Donatello turn away and blush profusely.

"I-I don't know, Raph. In case you've forgotten, everything in my lab was destroyed due to that explosion. All my tools, equipment, chemicals, everything. It's all gone."

"No." His eyes grew wide, grasping onto his head and shaking it in panic. "No, no, nononononononono. This can't be happening. This is not happening right now! I'm a guy. I'm a guy, Donnie! Guys don't have tits and a vagina!"

"Calm down, Raphael," Leo urged, placing a comforting hand on his terrifyingly anxious brother before flicking his eyes in Donnie's direction. "Donnie, are you sure everything got destroyed in your lab?"

"I-I haven't checked." He licked his lips and glanced over his shoulder, the smokiness coming from his lab starting to diminish. "But even if some things were salvaged from the fire, we have no mutagen, Leo. The canister that fell and transformed us into … girls was the retro-mutagen I made to transform April's dad back into a human."

"But I thought you said perfected it?" Leo pointed out. "You said you worked out all the components."

"Mutagen is extremely tricky and highly unstable," Donnie explained, feeling a hand drape over his shoulder to grab his attention. Standing next to him was Master Splinter, handing him a warm, fleece blanket to cover up his naked form so that they could all look each other without heating up in embarrassment. Nodding his head, he accepted the blanket, wrapping it around his lithe frame while continuing to speak. "I was looking over the compounds of the retro-mutagen the other night to see if I could reverse the effects so that it could transform us into humans. But because I hadn't found an effective reaction, I left it at that and that's when the fire started."

"So what are we going to do about April's dad?" Mikey asked, draping the blanket over his body. "She's expecting us to bring her the retro-mutagen to turn Mr. O'Neil back to normal."

"Well that should go over nicely," Raphael retorted, curling himself within the confines of his blanket. "'Hey, April. Sorry we don't have the mutagen we promised to bring over, but do mind if we borrow a couple of your bras and panties?'."

"Alright, knock it off, Raph," Leo ordered, wrapping the blanket around his body before looking at all three of his brothers. "Either way, we're going to have to confront April and explain to her what happened. We can figure out what we're going to do afterwards once we get everything cleared out and settled."

"So what, we just mosey on over covered in blankets and our birthday suits?" Raph asked, tightening the hold of his blanket around his body to make sure everything was covered.

"Do you think April will let us borrow some of her clothes?" Mikey asked a little too eagerly, his eyes lit up like a kid on Christmas morning.

Raphael snorted, flicking his eyes in the direction of Donnie while his lips split into a rather amused grin. "There ya go, Don. Who woulda thought all you had to do was turn yourself into a girl to get into April's pants."

"Shut up."
