They're losing. 

The battle with the Shredder seemed so easy at first glance. Donnie and his brothers had fought a million monsters like this before, and they'd always come out on top. 

This time, however, something is different. The Shredder is not fueled by the typical wants of a villain. He does not fight because he wants revenge or something petty like that, he fights for the sake of violence. 

He claws at the turtles, bearing his mouth full of dangerous knives. He's as fast as the wind, and always seems to be a step ahead of Donnie and his brothers. 

Raph had barked at them to all stay together, to keep each other in their line of sight. It was a good plan, but one that was flawed from the very beginning. 

The Shredder was cunning, even if he fought like a wild beast. With a few whips of his long tail and some slices of his dangerous claws, Donnie found himself alone-all the way on the other side of the shipyard. 

He's alone, shaking from exhaustion and pain from what is probably a sprained, or at least twisted, ankle. His staff feels heavy in his hands, heavier than it usually does. He clings to it, limping in the way that he thinks goes back to his brothers. 

The shipyard is full of massive crates, all of them looking almost exactly the same as the last. He can't even hear the sounds of fighting, the air feels still and heavy. 

"Raph?!" He shouts, "Mikey? LEO?" 

His voice echoes back at him, a haunting reminder of just how alone he is. There's utterly nothing, no sound, not even the whooshing of the waters from the nearby lake to cut into the silence. 

He comes to a sort of cross roads. A nearly perfect circle in the middle of the mess of crates, all of them pointed at him like massive blocky arrows. 

There is absolutely nothing here. His mouth feels like its full of mud, and his ankle flares up with fire every time he takes even the smallest step. 

His shoulders shake, the edges of his battle shell are digging into the sensitive skin of his shoulders. It was broken by the Shredder during the fight, and is practically falling off of him. None of the tech inside works. He's a sitting duck. 

Just as he'd started to pull out his phone, to maybe see if he could contact his brothers that way, a rumble starts. It's subtle at first, a mere tremble under Donnie's feet. 

That tremble grows into a shake, and then into a tremor. He doesn't have time to hide as the Shredder bursts from the distance, crates falling from his body like dead leaves from a tree. 

He moves so quick that Donnie barely has time to pull up his bo before the Shredder hits him. His claw hits the staff, and to Donnie's horror-cuts right through it like soft butter. 

"Fuck!" Donnie screams, dropping the sides of his weapon and scrambling backwards.

The Shredder snarls, his glowing eyes seeming to narrow when they fall on his form. He drops to all fours, moving not unlike a lizard. He twists around Donnie, knocking the turtle onto his front. 

Donnie puts his arms under him to push himself up, but the Shredder is once again right behind him. A massive claw slams into his battle shell, and with a growl it's ripped off of Donnie's back. 

Donnie screams, feeling the edges of his shell tear where the safety locks had tried to hold on. His mind goes blank for a moment, hazed over by the agony in his shell. 

Shredder rumbles above him, his metal face pressing against Donnie's sensitive shell. Donnie sucks in a sharp breath, ready for agony. 

Instead, what greets him is the sound of churring. It sounds wrong, though. Synthetic, if that were at all possible. It's grating, making Donnie's skin crawl but at the same time making his limbs turn to jelly. 

He slumps against the concrete of the port, his brain screaming at him to move as Shredder purrs at him. His breath is searing hot on Donnie's shell, and he shivers as the weird robot-monster thing curls over his body. 

A tongue slithers against Donnie's skin and he chokes, his body snapping out of the paralysis to kick at Shredder, screeching as the claw wraps around his shell and roughly flips him onto it. 

All of the breath shoots out of Donnie's lungs, stars flickering in his vision. When it clears, the Shredder is not looming over him. 

Or they at least aren't face to face. Instead, with one claw holding Donnie down by his plastron, Shredder's face slides down Donnie's front. 

He comes to a stop right above Donnie's cloaca. Suddenly, Donnie realizes what's about to happen. His stomach curls in terror, and his lungs feel like they're being squeezed. 

"No," he gasps, "no, no, no! Fuck-get off of me!" His voice raises to a shout, grabbing onto the weird spikes on Shredder's head and yanking fruitlessly at them. 

The Shredder doesn't listen, and Donnie screams as the monster opens his mouth and that same horribly segmented and slimy tongue slides across his slit. 

Donnie feels bile rising in his throat, and tears well up in his eyes at the feeling of Shredder's tongue curling over the slit. His tongue is incredibly flexible, with the tip having such terribly accurate precision that Shredder is able to slip the tip into the seam of Donnie's cloaca. 

His heart stutters at the feeling of the unwanted guest pushing its way inside of him. Shredder's tongue teases at his slit, the thin prick sliding up and down against the slit, and then worming its way in when Donnie's slit inevitably parts. 

"No," Donnie whimpers, his thighs clenching uselessly against Shredder's strength, "no, no, no, please, not there-" a weird sort of keening grunt leaves his mouth as Shredder's tongue shoves its way in a little further. 

"Don't do it, please, I'll do anything-just stoooOOOAH!" His cries peter off into a screech as Shredder's tongue shoves itself all the way inside. 

Donnie shakes as his cloaca is harshly split open. He can practically hear the muscles there straining, as Shredder's tongue keeps coming. 

The tongue coils around, turning into a spring sort of shape before it becomes boneless again. He feels it tease at the cusp where Donnie's dick will drop. 

Tears well up in his eyes as he feels his dick start to shift. His head thrashes from side to side, sobs leaving his mouth as Shredder's tongue wraps around his penis and begins to pump. 

Donnie howls, his spine arching as far as it will go with Shredder's weight on him. He strains against Shredder, sobbing so hard that he chokes on his own snot and saliva. 

"Take it out!" He screams, wincing as the tongue pushes too far and makes something inside of him pinch, "please! Stop! Let me go, please I don't-"

The Shredder continues, jerking at Donnie's cock until it fully drops into Shredder's waiting mouth. His mouth is freezing compared to the tongue and Donnie's cloaca. Almost to the point of pain. 

The tongue jerks at his dick, making Donnie jump and moan against his wishes. Tears leak out of his eyes freely, his struggling starting to wane as pleasure takes over. 

His orgasm is slow and creeping, and it makes Donnie want to vomit. He can't be getting off from getting raped. This isn't right, he doesn't want this-

"Augh," he moans, his thighs starting to shake for a different reason. The pressure inside of him making him keen, and soon enough he feels his dick start to pulsate. 

With a sob and shaking his head, cum starts to leak from his cock. His cock jumps weakly, once, twice, and then starts to become soft. 

Donnie sniffles and whimpers, having no choice but to stare up at the night sky. Shredder's tongue unravels from his cock, a slow coiling motion that has Donnie yelping from overstimulation. 

Was it over? Donnie prayed so, squeezing his eyes shut as Shredder shifted above him. After a moment, he peeked open his eye. 

Shredder hovered above him, a sort of concentrated look on his metal face. There was the gentle shifting and clinking of metal moving against itself, and then Donnie felt the heat of a massive cock touch against his cloaca.

"No-" Donnie gasped, looking up at Shredder who seemed to grin, "no, no, no, that won't fit!" He choked out, new tears gathering in his eyes as Shredder starts to shift his hips. 

"That won't fit!" Donnie's voice hikes up to a scream, "it won't fit, stop it!" He tried to angle his hips away but that only seemed to spur Shredder on. 

Shredder pulls his hips back, and for a blessed second Donnie thinks that the monster will just kill him and leave his body. That sounds like a better outcome than this one.

His dreams do not come true, and Donnie screams as the bulbous tip of Shredder's cock shoves past slit. The stink of blood fills the air and Donnie knows that he's been torn. 

Clenching his jaw, he squeezes his hands into fists and does his best to relax as Shredder pulls back slowly. There's a second of nothing, and then Shredder shoves back in. 

His movements are all violence and no love. Each thrust shoves his cock a little further inside of Donatello. Each inch more from the cock feels like it's splitting Donnie down the middle. 

When Shredder finally bottoms out, it's almost a relief. Shredder is pushed deep into Donnie, and the turtle can see the way that his plastron flexes a little from the girth. 

Shredder pulls back slowly, and Donnie lays his head back and tries to be anywhere but in his body. He feels the slide of Shredder's cock against his stretched out walls and shivers as a cruel spark of pleasure thrills in him. 

Every thrust has Donnie jolting up, his breath knocked out of his lungs each time. Eventually, moans start to join his grunts and wheezes of pain. 

Harsh pants of ecstasy leave his mouth, joining the moans. He barely feels it when Shredder lifts his hand from his chest. The huge monster purrs at his pleasure, metal nose rubbing against Donnie's tear-wet skin. 

Heat pools through Donnie's body, rushing through his veins to drop itself off into his cloaca and cock. He feels terrible, like the worst monster in the word, for being pleasured by his worst enemy. 

He starts to drool, his eyes rolling back as Shredder shoves up against all of the best places inside of him. Slowly, like there's a break in his skull, his thoughts start to roll out of him. 

His hands shakily come up to grab onto Shredder's arms to pull him closer, rather than shove him away. His moans fill the port's atmosphere, and his throat starts to ache from his grunting and moaning. 

Shredder's thrusts start to stutter, the rhythm of his hips shifting to something more frantic. Donnie's mouth snaps shut in a hiss as Shredder shoves in as far as he'll go and then stops.

The stretch makes Donnie choke on a sob, and then Shredder starts to come. It leaks out of Shredder's cock, shoving a heat he hadn't known before into the deepest parts of him. 

Donnie's own orgasm stutters out, and he shivers in disgust at the feeling. Shredder's cum fills him to the brim, and when the monster starts to pull back, Donnie can feel the viscous liquid shifting around his length. 

Shredder grunts as his cock pops out of his cloaca, and his cum gushes out. Donnie lays there, staring at the stars again as Shredder stands up to his full height, shakes the endings of his stream of cum onto Donnie's face. 

Then, the monster leaps from the ground into the air, and he's gone. Donnie lays there, heaving out sobs as his body registers the total agony he's in. 

Beside his ear, he can hear someone crying with him. The voice is crackly, like it's being transmitted through a...

...A phone. 

Donnie rolls onto his stomach, ignoring the horrible feeling in his tail. He curls around the phone, his eye sight bleary as he stares at the screen of his phone.

Mikey

Call time: 10:45

Donnie blinks at the numbers numbly. His throat is ragged and raw, and his words feel like ash as he speaks them. 

"Mikey," he croaks. His brother sobs over the phone. In the background, Donnie can hear the sounds of fighting. 

"Don't," Donnie coughs, bile trailing out of his mouth and into a puddle below his head, "don't be alone-find Raph-"

"Find Raph?!" Mikey scream-sobs over the line, "I have to find you-Shredder can wait! I need you!"

"You need to stay safe," Donnie grits out, "Shredder will tear you apart if you stay where you are." He lifts his head slowly, and sees a plume of smoke raising over the battle. 

"Donnie," Mikey wails, "Donnie I swear to fuck if you leave me-"

"I'm sorry," Donnie whimpers, "I love you, I love you-" he chokes as he feels the cum slosh around inside of him, "find Raph, he'll keep you safe. Please, please," his lips wobble as he feels the cum deep inside of him starting to swirl. Mystic powers curl around his cells, and Donnie falls flat on his face as he feels the cells split. 

The world spins, and Donnie sees none of it. He can feel mystic powers winding through him, curling around the eggs that are starting to form. 

"DONNIE!" Mikey's scream sounds different, clearer. Donnie blinks, and somehow he's on his back. Mikey hovers above him, his face soaked with his tears. His mouth is moving like he's speaking, but Donnie hears none of it. 

He blinks, and looks past his little brother at the stars. They look so nice tonight...
