Shredders Revenge

Things had been relatively uneventful since the Shredders defeat two years ago during the Triceraton invasion. There had been the occasional issue with Bebop and Rocksteady, plus a resurgence of the purple dragons. Nothing that the turtles couldn't handle. In that time Casey's family moved away and April had graduated high school and was looking forward to college. Everything seemed to be perfect in the world as Raphael and Michelangelo headed out alongside April to go buy a half dozen extra-large Pizzas.

Donatello regretted not volunteering to go help pick it up once April decided to go with his two brothers. He was sure she only joined them to keep the two from fighting, but it sucked that she was choosing them over him. He was so wrapped up in his thoughts that he didn't notice when a dull vibration began to rattle the pictures on the wall of his lab. Leonardo and Splinter were meditating in the dojo. They two were oblivious to the sound and were finally alerted by the sound of shattering glass. “What the hell?" Leonardo managed to say before a bunch of bricks burst out of the wall, showering the two in dust and rubble. Donnie ran into the room with his bow staff ready as a second spray of debris shot out, growing the hole larger. Dust obscured the opening as echoes of metal scraping against stone and the whirling of servos could be heard approaching. The noise seemed familiar, but none of them could quite put their finger on where it was from. Then they saw it, the shine of polished steel and a single glowing red eye.

"Mousers?" Donnie said taken aback at seeing the small robots. "What the heck are these things doing here? I can't believe there's any even still working." The tall green turtle jumped out of the way as one of the diminutive raptor like robots jumped at him. The small robot crashed into a cabinet, sending splinters of wood flying. A split second later Donnie smashed his staff down into its head, smashing it in.

Another mouser jumped towards Leonardo, only to be swiftly cut in half by his katana. "What do you mean still working? These things look brand new!" Another flash of his twin swords split a pair of the chomping robots in twain.

"Well, I just mean why would anyone would keep building these things? I mean there identical to the old mousers. There's not even so much as a minor upgrade to their materials on them." Donnie said batting one into the wall.

"Uh, maybe because Stockman is an idiot." Leo retorted as he leapt over a group of snapping metallic jaws.

A half dozen kunai flew across the room, spearing several more of the bots. They toppled over, spewing sparks which danced across the ground. "It is fortunate for us that they have not been improved. However, the danger they posed never came from their strength." Splinter said before throwing several more kunai. "It came from numbers."

"You're right sensei, and judging by the sound of it I'd say that hasn't changed!" Leo yelled as a new hole was formed in the wall on the opposite side of the room. A dozen new mousers spilled through it and began to scurry towards the three fighters.

Donatello destroyed another Mouser, then narrowed his eyes as he looked at the approaching horde of metal. "Leo, I need your T-phone."

"What? Now's not exactly a good time to be making a phone call!" The blue clad turtle said as he parried a pair of lunging mousers.

"I'm not going to make a phone call. I think that I can jury rig the speakers in our phones to create a short range EMP if I can make a small modification and then pass enough current through them. Well, that or blow out our ear drums with a deafening high pitch squeal. Actually, now that I think about it, I suppose it is possible both things could happen if..." Donnie's rambling was cut short when he barely reacted in time to catch the shell shaped cell phone that was flung at his head. Leonardo and Splinter did their best to cover Donnie as he worked. Despite their best effort, it was a losing battle. For every mouser they destroyed, two more took its place. The floor was a sea of metal that was about to overwhelm them when Donnie yelled, "got it!" A moment later the robots all seized up, convulsed for a few seconds, and then collapsed to the ground. Several began to spark and a few pops could be heard as some of the electronics caught fire.

The three men sighed and collapsed to the ground catching their breath. "I am getting too old for this." Splinter said after a minute, then pushed himself back to his feet.

Donatello and Leonardo stood up a few seconds later. "Why would Stockman come after us now? It's been years since we saw him. Honestly, I wasn't even sure he'd still be alive given how long flies live." Leo said as he slid his swords into their sheaths.

"Perhaps it was not stockman who made these. Someone may have simply unwittingly activated mousers that were lying dormant somewhere. Regardless, we must find out where they came from and who knows the location of our lair." Splinter said resolutely.

Donnie walked a few steps towards one of the mousers he had taken out and knelt down by it. "Maybe I can repair one of these enough so that we can follow it back to wherever it came from?"

"Didn't they all get fried by the EMP?" Leo asked as he casually turned one of the smoldering robots over with his foot.

"Maybe not all of them. Some of the ones further away might not have been effected as much. They may have only had their power source disabled or might have automatically shutdown to prevent damage from an overload. Give me a few minutes to look at a couple of them." Donnie said, picking up one of the small robots.

Splinter nodded his approval. "Very well Donatello. Meanwhile, Leonardo and I will prepare ourselves."

"Are you going to come too Sensei?" Leonardo asked surprised that Splinter would accompany the two of them on such a menial mission.

Splinter nodded his head as he stroked the well-groomed fur on the end of his chin. "Yes, I fear that there is more going on here than we realize. With the destruction of your T-phones, we have no way of contacting the others, and we cannot risk waiting for them to return. It is possible that there could be a second attack on the way, or even that the others have been captured. We must be very careful moving forward, but we must also be swift and decisive with our actions."

An hour later a lone mouser with a dented head limped down a trash laden alley. On the roofs above the three hero's shadowed the reprogramed robot. It had led them half way across the city moving into decreasingly populated areas. As the buildings began to become smaller one stood out and their destination became clear. A large warehouse flanked on all sides by large shipping containers. It had several broken windows and was covered in spray paint. From all appearances, it seemed to be abandoned, which was exactly what Splinter had expected to see.

Once it was clear what their goal was, the three split up. Leonardo and Donatello circled around the building, surveying it while they went. Meanwhile, Splinter moved atop a crane to get a clean view of the surrounding area. Large cargo containers were everywhere, stacked between one and three high creating a maze of multi colored corridors. Through those narrow alley ways, packs of five or six mousers roamed. Though it was hard to tell at first, the seasoned rat soon realized that each group seemed to be a uniform distance from the next and previous. Knowing that, and knowing the layout around the building revealed a single weak point. For a very brief period of time, there was a blind spot between groups as one entered the maze of containers, and the other rounded the corner of the building. This period of time would normally be too short for anyone to take advantage of, but for ninjas, it might as well have been an eternity.

The three silently slipped into the building via a broken sky light. They made their way along one of the supports, peering down into the darkness below. It almost appeared to be a regular warehouse filled with wooden crates and a floor that was caked in dust. Only the oversized cabling that ran into one of the particularly large crates gave away the truth. "There," Leonardo said pointing to the crate. "I bet whatever we're looking for is under that."

Donatello jumped down first to examine the cabling, followed quickly by Leo and Splinter. "This is some heavy duty wiring. Whatever is down there must be drawing a lot of power, and..." The purple clad turtle stood up and pulled back a piece of wood on the box revealing a number pad. "I don't think we can simply push this out of the way." He pulled a small knife out of his belt and opened up the panel. He gently used the tip to separate a number of colored wires, tracing them to see where they went. Eventually, he isolated and cut one, then shut the panel. "Well, cross your fingers." He pressed the enter button on the pad. After what seemed like the longest 5 seconds, a click was heard and the door hidden in the side of the box swung open.

There was very little inside the box. A single hole was what immediately caught their eyes since light was spilling out and creating an outline around the cables that were feeding down into it. The whole was about six inches across and seemed to go straight down, though it was hard to say how far. The only other thing that stood out was an old set of rusty metal stairs that went downward. None of them particularly liked the idea of going down a narrow path with one easily blockable exit, but they were left with no choice. Down they went, slowly creeping forward, being careful to make no noise. The deeper they got the more they began to notice a low droning. When they finally got to the bottom, it was clear what was causing it, one or more large fans that were somewhere ahead. It was so loud that they could almost talk normally and it was no more noticeable than a whisper. That deafening noise is what allowed the three to be snuck up on. It was only the quick reaction of Splinter that prevented a mouser from getting its sharp metal teeth into Leonardo's neck. Instead, it simply got a mouthful of the rats walking staff. The four other robots that had moved in on them didn't even have time to try and attack. The two turtles quickly dispatching them with a flurry of attacks that reduced them to pieces.

Fearful that the element of surprise was now gone, the three chose to be bold. They rand towards the source of the noise, reasoning that it most likely was where their enemy would also be located. After about 30 seconds of running, they came to a locked door that once again had an electronic number pad preventing access. However, this time Leo didn't give Donnie any time to bypass it, instead he simply kicked the door in. The three entered the room ready to fight, but there was no one there. The harsh florescent light revealed a dozen table sized 3D printers, a half dozen tables with shackles built into them, two refrigerators with glass doors filled with various objects, and several server stacks that probably accounted for some of the fans they heard.

"Well, I'd say this is where the mousers were fabricated, but what's all this other stuff for?" Leonardo asked, sheathing one of his blades so he could pick up a half constructed robot head.

Donnie nodded his head in agreement. "Let's see who is behind all of this." The purple clad turtle walked over to the computer in the corner of the room and moved the mouse to wake it up. As soon as he did a loud clank was heard as a metal shutter came down in place of the broken door, followed by a soft hissing noise and a second later by white gas that began pouring from the ceiling vents. "Oh, crap." He said trying to log into the computer to deactivate the gas, only instead he was surprised to see that thing didn't work at all. "Uh, I can't stop this."

Leo ran over to the door and tried to jam his sword into the gap and use it as a lever but he couldn't even get it to budge. "It's no use!" He yelled before breaking out into a coughing fit. Splinter and Donnie likewise began coughing uncontrollably before falling to the ground. A few seconds later they were all unconscious.

---*---

Leonardo awoke some time later. His eyes were heavy and his vision was blurred as the effects of the knock out gas slowly waned. He moved his right hand to rub his eyes but found that something was holding it in place. A strong metal band was tightly clamped around his wrist, keeping him from doing much more than rotating his hand. With his vision still blurred he turned to look around the room. Though it was hard to tell with absolute certainty, it looked like Donatello was strapped to a table that he guessed was the same as the one he was on. Beyond Donnie, he could make out a blurry brown shape that had to belong to Splinter. The rat was half obscured by the unconscious turtle, but from the little Leo could see, it appeared that he was hooked up to some kind of I.V. that was pumping him full of a florescent violet liquid.

"It's about time you woke up." A familiar feminine voice came from the opposite side he was facing. He turned towards her with a look of surprise on his face.

"Karai! You're alive? We all thought you died two years ago. What are you doing here?" He asked as he once again tried to move, forgetting how he was bound.

Karai smiled at the blue clad turtle and ran her hand gently down the side of his head. Leonardo blushed involuntarily as he tried to get a better grip on a situation that seemed to be increasingly dream like. "Relax Leo, everything is going to be alright."

"Then why did you knock us out and strap us to tables like this?" Leo asked, doing his best to assert himself and get some kind of reaction out of the woman.

It didn't work. Karai remained calm and in full control. "Well, I suppose I could have just called you up out of the blue. I'm sure you would have come running to meet me, but one of your brothers or April would have almost certainly noticed you slipping out and followed you. Who knows what they would have done, so instead it was easier to give you what you expected, an enemy to fight. You're so predictable when you play hero. We just had to make it believable enough for you to not be suspicious."

"You nearly killed us at the lair." Leo spat at her as he felt his strength coming back and his vision clearing.

The human shrugged her shoulders. "That was a bit unexpected. I mean I figured mousers shouldn't be that big of a deal for the three of you to handle. You must be out of practice."

"Why don't you let me out of these bindings and see just how out of practice I am?" The turtle said through clenched teeth as he strained against the metal.

"Don't worry, I'll let you out of those soon enough. I just need to make a few minor changes before that." Karai said as she held up a terrifying looking injection gun with a 3 inch long needle and a large vial of silvery liquid attached to it. The table he was bound too began to rotate, moving him to a vertical position while at same time a strap extended and tightened around his head, immobilizing it. The human went around behind the table once it was fully upright. When she was out of view he felt something sharp prodding the back of his neck. "Oh, this might be a bit uncomfortable by the way. I'm afraid this needs to inject straight into your nervous system. I'm sure it won't be too much for a strong guy like you to handle." Leonardo let out an ear shattering scream as she pushed the needle deep into his neck and slowly delivered the metallic liquid. She pulled the needle out a few seconds later and put a bandage on the wound as the turtle shivered and occasionally convulsed as he was trying to deal with the pain. "See, that wasn't so bad."

Leo glared at her as he circled around back in front of him. "I know this isn't the real you Karai because even at your worst you weren't this much of a psychotic bitch!" He screamed.

Karai gave the turtle a condescending look. "Oh please, it's not my fault that you have a high metabolism. We did the whole procedure to Donatello while he was unconscious. You just have really bad luck but don't worry, once that gets fully integrated into your system we'll change all of that."

"What does that mean?" Leo asked feeling the pain finally starting to wane.

"Well, it's a bit complicated so it might be easier to just show you." The woman said picking up a tablet and showing him it. There were a good number of words he didn't have time to read as she waved it in front of him, but he did notice a number of buttons and sliders that seemed to be important. She tapped her finger on the screen then slid it to the right. A moment later he started to feel funny then blushed bright red as he realized what was going on. "The injection contained hundreds of thousands of nanobots that have infiltrated your nervous system, brain, and well pretty much everything else. Currently, they're causing your body to become aroused. Normally you seem to be able to suppress this, even when you're around me." She said winking at him, making him gulp. "I guess it must be due to your discipline, but that won't help you this time. I've always wondered what a mutant turtle looks like down there. I did a little research after we first met and let me tell you, turtles have some interesting attributes. I wonder how much of that stayed intact after your mutation?"

Leonardo noticed Karai licking her lips, but it wasn't with her human tongue, it was a serpents. He guessed that she was getting into this, and he didn't know if that was a good or bad thing. What he did know was that she was telling the truth. He was trying with all his might not to show her anything, but his dick simply wouldn't respond to him. Slowly the pink tapered tip that formed an arrow like shape appeared out of a slit she hadn't noticed before. As it pushed further out it quickly grew wider creating a bulge several inches behind the tip that grew wider the further back it got until it had to be at least eight inches across. After 30 seconds his dick was a foot long, throbbing and heaving with red and blue veins visible all along its length. It continued to grow longer, seeming to have no end as it slowly pushed up his belly and chest. After a minute he was almost as long as her arm and he still wasn't done. Finally, he reached his full erection with the head of his cock reaching so far up he could suck on his own dick with ease had his head not been restrained.

"Oh my god, it's amazing!" Karai said in awe of the organ that stood before her. She reached out and gently wrapped her fingers around the base of his cock. It was a little narrower than the main section of his shaft, but even then it was too much for her to be able to touch fingers together. She slide her hands upwards, feeling the warm flesh pulsing under her touch. Leo gasped and tried to mutter something that sounded like begging her to stop. "I don't think you really want me to do that." She said continuing to move her fingers upwards until she finally reached his pointed tip. There she used her thumb to tease his slit, getting it soaked in slippery precum. Making sure he was watching her, she brought the thumb to her mouth and sucked it clean. "Mm, that was even better than I dared to dream." She smirked at him as he subconsciously smiled back at her.

Karai considered continuing to play with him but sighed when she remembered her duties. She picked up the tablet again and clicked a series of buttons that controlled the turtle's memories. Then she glanced over at the still unconscious Donatello and smirked as she moved the slider that controlled his arousal and set it to maximum. She returned her attention to Leo, noticing that the nanites appeared to have begun their work. For the next hour or so he'd be completely open to any suggestion. "Remember when we first met Leo, how you were instantly attracted to me. Remember how you would rebel against your brothers and master just to be with me." Leo nodded his head in agreement. Karai licked her lips, once again with her serpent tongue. So far nothing she said was wholly untrue, but he seemed so responsive that she was really starting to think that this plan might work. "Do you remember when you snuck into the heart of the Foot's compound to sneak a look at me in the shower?"

"Of course, you were so beautiful," Leo said in a dazed state. "I wanted to slip in closer and join you." He added much to her surprise. She had forgotten that the nano-bots did more than just rewrite his memories. They also filled in areas where contradictions might occur, basing them off of the persons own desires and personality so that nothing was out of place.

This gave her an idea. Karai looked at the turtle that she had shared a crush with for the last 3 years of her life, and while she had new commitments to attend to now, she still couldn't help but want more from him. She needed to turn him to the side of the Foot, but there was no reason that she couldn't get something out of it too. They'd finally be together like both of them had secretly wanted but could never fully admit. "Remember when you fought the Shredder and you lost to him. Your swords were broken and he was about to strike the final blow. It was only my request that saved you. You went back to your brothers in defeat but you couldn't get me out of your mind. You continued to oppose my father, but your heart wasn't in it. That's why..." She hesitated for a moment thinking about what would happen if she said what she was thinking. Once his memories set, she would be committed to whatever he remembered. If she promised him something here, she'd have to follow through on it. "That's why I eventually convinced you to join the Foot. Father thought it was simply because you saw how much stronger he was than Hamato Yoshi, but the true reason was because of my promise. Six days of the week I would be a loyal Kunoichi of the Foot, but one day of the week I would be yours alone to do with as you please."

"It was the best decision of my life," Leo said with a toothy grin as he looked down at her with lust filled eyes. She blushed for the first time, thinking about what they would do in the coming weeks. She cast her eyes to his dick, seeing it dribbling precum now and couldn't help but lean in and give it a long lick. She swallowed a mouthful of the salty liquid then shuttered in anticipation as she made her way towards Donatello.

The purple clad turtle was already fully erect when she arrived. As she looked at his dribbling cock she bit her lower lip. She couldn't be sure, but she guessed that he was a little bit longer than Leonardo and just a bit narrower. Of course, those differences were miniscule since both of them were so huge no normal human could handle it. That idea is what made her so turned on looking at it. She wasn't a normal human, she was one of the few that would actually be able to appreciate and enjoy them. She held up the tablet and activated the same brain influencing commands on Donatello along with a command to wake him up. In the meantime, she couldn't hold herself back from playing with him. She crawled onto the table, straddling his body. She could feel the turtle's impossibly large dick pressing against her dampening pussy. She ground herself against him, feeling the heat through the thin clothing that separated them. Then she reached down and pulled his dick back so that it was pointed more up toward her, finding it to be quite heavy as she moved it. Once she had it a bit closer, she leaned down the rest of the distance and began to lick the underside of his cock up to the tapered tip. Over and over again she did this, making him moan softly until he finally regained consciousness.

"Oh, April, I don't think I've ever... Karai, what are you doing!" He said with wide eyes as he tried to cover himself. Of course, he failed since he was bound, but the woman still giggled at the attempt. "What are you talking about Donnie, don't you like this?"

A haze came over the turtle, which his analytical mind just chalked up to the pleasure he was feeling. "Oh god yes!" He said as he watched her give him a few more licks.

"Naturally, after all, this is why you joined the Foot." The woman said before sucking on the tip and gulping down a mouthful of his precum.

Donnie gasped loudly but fought off the urge to thrust. "I don't... I don't know what you mean by that." He said in a tone that showed he was trying to remember, but couldn't quite get there yet.

"It was after Leo left you and your brothers to join the Foot. You tried to make a move on April, but she shut you down." Karai said, then stopped for a moment as she thought about the red head. It was humiliating that April had managed to beat her in a fight. She wasn't even a real Kunoichi. Now Karai had the turtle that had such a crush on that bitch moaning and squirming under her touch, and she could use this to her advantage. "Actually, that's putting it lightly considering how long she led you on only to end up having a threesome with Casey Jones and Raphael. I mean, Casey I kind of get since he always liked her but Raphe too? She must have done that just to hurt you." Donnie's face contorted to rage as he remembered her doing just that to him. "That's why you jumped at the chance to join the Foot, be alongside your brother Leo, and of course me. Father doesn't know, but one day out of the week I spend with you alone." She looked over at Leo and quickly added quite loudly. "Well, you and your brother I mean."

"Of course Karai, it's what I look forward to most," Donnie said with a grin. Then Leo also chimed in, "brothers should share everything after all."

--*--

Splinter awoke to darkness. His body felt strange, and his wrists hurt as something seemed to be digging into them. It was the feeling of metal, some kind of handcuffs or other bindings. Likewise, he could feel something similar on his ankles, though it was less uncomfortable there. Even his tail seemed to be held in place by something.

"Welcome rat, to the end of Hamato Yoshi!" Came a deep, ominous voice from the darkness.

Splinter recognized it instantly. "Saki! How many times must you be vanquished before you finally die?"

A deep laugh came from the shadows. "Yes, it is true that you bested me. More than once even. For too long I deluded myself into thinking that I was stronger than you simply by force of will. In our last battle, I was nearly killed. I burned with hatred for you, I was willing to do anything to kill you. My vengeance nearly consumed me. I was committed to becoming a monster if that's what it took. Then after weeks of seeing your face in my nightmares, I realized something. I wasn't seeing Hamato Yoshi the man, I was seeing Splinter the rat! That's when I understood. As a man, you were an annoyance, but as a mutant, you were a greater threat than I ever gave you credit for. Your four sons defeated armies of invaders and my own Foot, yet the mutants I created paled in comparison. Why was that? Because they were unworthy. It takes a great man to become a great mutant, and that is what I have become."

With that the lights came on, revealing shredders mutated form. Splinter gasped as he saw the towering sabretooth tiger mutant in front of him. In many ways, his new form was just a more enhanced version of his human body. He had an even broader chest and more muscular arms. His legs too were stronger than before, but what stood out most of all was the two large teeth that protruded down from his mouth. He had a new set of armor, better designed to fit his new form, but it still clearly resembled the armor that he had always worn. The only clear differences were the alterations for his tail and the lack of a mask. Part of that was because of his fangs, but also because the scars from his burns were now gone, replaced by a handsome feline face with magnificent fur.

After Splinter was done taking in his enemy's new form, he noticed the small Asian woman that barely came up to his waist. "Miwa!" He yelled, straining at his bindings.

"Hello, father," Karai said coldly before bursting out into laughter.

"What have you done to my daughter?" Splinter yelled angrily at Shredder.

Karai responded. "Master Shredder saved me from my foolish attempt to rebel against him. He is my true father. You are merely the person that provided half of my genes. He raised me and loves me, and I love him." Shredder lifted one of his massive arms and pat her on the head. "Besides, how could you ever really be my father when you're not even a man?"

Splinter was confused at first what she meant, thinking it was just some random insult about being a rat. Then he glanced down and saw that his chest looked quite large. Also, now that he thought about it his arms looked a tiny bit narrower than normal, but it was a bit hard to say because of his purple robe.

Shredder took a couple of steps, bringing him next to the rat. He positioned his twin steel claws under the fur of Splinter's throat. "Confused rat? This is what she is referring to!" He turned his wrist over and slashed downward. The robe was cut to ribbons revealing Splinter's naked body. Gone was the toned pecs, instead there were two large breasts covered in light cream colored fur. Her waist had gotten thinner and her hips had widened along with her rear. Most importantly, the long cock she use to have disappeared, replaced by a tight virgin pussy.

"Why? Killing me I understand, but what do you gain from this?" Splinter asked, noticing her feminine voice for the first time.

"I get entertainment," Shredder said with a grin that showed off his sharp teeth. Then he walked past the nude rat and took a seat in his throne. Karai stood next to him and awaited his command. The sabretooth mutant snapped his fingers and she gave him a tablet that controlled the Nanobots inside Splinter. He found the slider that controlled her arousal and moved it to maximum. Then he clicked on the lock icon next to the slider, which opened up a text box that read: Warning, after 24 hours the units system will be permanently set at this level. This cannot be undone after 24 hours. Proceed? Shredder grinned, then hit the button to proceed and handed the tablet back to Karai. "Let the show begin."

The door at the end of the room opened, revealing the Foot's two newest warriors to Splinter. Leonardo and Donatello entered the room, wearing black head bands and on their belts the symbol of the Foot. Both men wore evil looking grins. "My sons! What have you done to them?"

"We had our eyes opened. I was a fool to try and fight the Foot. It takes strength to bring order to the world, and they have that strength." Leonardo said cruelly.

A moment later Donatello spoke up in a matter of fact tone. "Plus they have the money and resources necessary for me to conduct my research. Imagine what I can do with all that."

"No my sons, he has poisoned your minds. This isn't how I raised you to think and act." Splinter pleaded with the turtles.

Leo laughed at the rat. "Maybe that's true, but you know what else is? I've never felt more alive than I do right this moment. Shredder did that for me, not you. You had your chance, and you blew it. That's why he's sitting on a throne, and you're literally going to be his bitch."

"Listen to your son Splinter, you know he's speaking the truth," Shredder said in a thunderous tone. "Now, it's time for your training to begin, my new concubine."

The two turtles began a slow march toward the bound rat. As they grew closer she noticed their pink cocks starting to poke out. "Please stop, fight this!" They ignored her, and when they finally got close enough to touch her they were each close to a foot long.

"Let's see what this new body of yours can do sensei," Leo said with a smirk as he reached out and grabbed her pussy, slipping one of his wide fingers inside. She gasped as he violated her new snatch and moaned loudly when he started to wiggle his digit around inside of her. Donnie took one of her large breasts in his hands, observing her reaction as he squeezed it. Then he flicked his thumb across her erect nipple, seeing how she shuttered with pleasure at his touch. He leaned in and slipped his mouth over her nipple, then began to suckle on it. A moment later Leo pulled his finger out of her and did the same with her other breast.

Splinter moaned as her two sons sucked on her tits, feeling their teeth gently teasing her sensitive flesh. It was a brand new feeling for the rat, one she could barely understand. She didn't want to like it, yet for a reason, she couldn't comprehend, she did. Donatello moved one of his down and grasped one of her firm butt cheeks while Leonardo did the same to the other. Together they spread her rear apart so that Shredder and Karai can get a good look at her tight anus and dampening pussy. Then together the brothers moved their hands down and each insert a finger into her cunt, making her gasp loudly.

Shredder looked at his daughter. "Tell me Karai, what are you feeling as you watch your friends molest the rat that use to be your father?"

Karai put her left hand on her father's massive leg, then moved it inward to caress his inner thigh. "I feel horny." She said feeling his bulging crotch against the back of her hand.

"As do I, perhaps you would like to help me with that," Shredder said suggestively.

His daughter grinned. "It'd be my pleasure." She said moving her hand up to undo his pants.

As Karai worked to get at Shredders cock, he clicked a button which released the shackles holding Splinter in place. As soon as her arms and legs were free she was instantly grabbed and held in place by her two strong sons. "That is an excellent start, now bring her closer. I want to see the look of defiance drain from her eyes as you break her in."

The two turtles dragged the rat towards Shredder and turned her around to face him. The rat's mouth opened in disgust as she saw her daughter pulling out the feline's cock. Karai glanced at Splinter and flashed her a smile before leaning in and taking the tip of the sabertooth's dick into her mouth. "Saki you bastard. I did not think that you could sink to such a level. You are disgusting!"

Shredder gave a deep laugh. He placed his giant paw on the top of Karai's head gently suggesting to her that she should go deeper. She eagerly complied, feeling some of his barbs enter her mouth as the tip hit the back of her throat. She let out a loud "Mmmm" to show how much she was enjoying it.

The horrified rat let out a soft "no" as she watched her daughter starting to deep throat the thick feline cock. Shredder leered down at his old foe, enjoying the look of defeat on her face. "You need to learn your place, and what that mouth of yours is for. Show her." He said coldly to the two turtles.

Leo and Donnie forced Splinter down to her knees, putting both mammoth dick heads well above her eye line. For the first time, she really noticed just how gigantic their meat rods were. It was terrifying to see. They couldn't possibly expect her to take those, could they? "Get to work whore!" Leonardo ordered as he forced his shaft into her face. She took a deep whiff of his rod and it filled her with a heat and desire she'd never felt before. "I will not do this." She said to herself as much as to them. A three fingered hand grabbed hold of the fur on the back of her head.

"You don't have a choice rat!" Donnie said as he pulled her back. At first, she didn't realize what he was doing, but then she saw Leonardo angling his massive dick down toward her maw. "Obey or else." As expected she continued to resist, so Donnie forced her head forward onto his brothers tapered dick. Her mouth was instantly filled with Leo's dribbling cock. His precum filled her mouth and made it water with desire. For a brief second it didn't seem all that bad, but then she was forced further down. Her mouth stretched wide as she was driven down beyond the head of his cock. Soon her throat was being speared making her gag around him. Her jaw ached and threated to be disjointed just to allow more of her son's dick into her mouth. That wasn't the worst of it though, the worst thing was that a small part of her would be happy to do that if she could take more of him. Suddenly she was pulled back without warning, sending her into a coughing fit. Before she could even recover Leonardo had grabbed hold of her head and was forcing her down onto Donnie's long, thick manhood.

Karai had moved to be on her knees between Shredders legs, allowing her a better angle on his dick. She bounced her head up and down his cock, feeling it stretch her jaw wide as her serpent tounge reached further down to massage the part she could not fit. The sabretooth mutant stroked her hair as she worked. "I know what you did daughter. Did you think I wouldn't keep an eye on you as you conditioned the turtles?"

The woman pulled off his cock with a loud, wet slurping noise. "I'm sorry father. I didn't mean to offend you, but I couldn't help myself."

"Of course you can't, you get it from the rat over there. There's a desire inside that you can't control." She looked over at Splinter, seeing that despite the constant gaging and choking the rat had begun to move her head on her own up and down her son's shafts without even realizing it. "I know there size is intoxicating to you."

"They may have size, but they lack experience like you," Karai said, but she was cut off before she could add any more.

"Do not lie to me, I know you'd prefer to be stretched to the breaking point and used like a fleshlight. I do not need you to sooth my ego. Besides, why should I be jealous of them when I already have the capability to make myself their equal in size and girth?" Shredder said with a sly smile as he watched Karai's eyes widen in wonder. He pulled out a syringe gun filled with some kind of mutagen then injected it into his neck. "I am the ultimate mutant, I cannot be bested in any way."

Karai leaned in and gave his cock another long lick from base to its tip, subconsciously measuring him as she went. He was 14 inches long and around 3 inches wide with heavy furry balls. Then she gave him another lick and he was at least 16 inches and probably wider too. "Oh father, please let me apologize to you properly forever doubting your greatness."

"Hmm, an apology may not be enough. You need to be properly punished." He said grabbing her by the arms and lifting her up above his now 18 inch cock. He lowered her down onto its tapered tip, prodding her virgin anus with it through the tight cloth that conformed to her crotch.

Karai moaned loudly as his cock continued to grow, entering her ass along with the stretching clothing. "Oh daddy, you're so bad!" She squealed in delight. The more he filled her the tighter her clothing got, digging into her wet pussy and making her bite her lip. Just as it was getting to be too much for the dark haired woman, the loud sound of tearing fabric could be heard and she felt the feline's warm dicks flesh against her skin for the first time. A second later she felt Shredder move his clawed hand to her chest, carefully taking hold of her chest armor and ripping it off her, along with the entire front of her leotard. She sighed contently as she felt the cool air against her pert breasts and shaved pussy. "How big are you going to get?" She asked her adopted father as she felt his barbs starting to tickle her intestines.

"At least as big as one of them, probably even bigger!" The large cat said as he forced the human down all the way to the base of his length. Karai let out a scream of pleasure and pain as her belly stretched out, showing the clear outline of cock. "What's important is that it's big enough to please you." He added as he started to lift her up, then pushed her back down on his dick, using his daughter like a sex toy.

Splinter heard the scream of her daughter, but it barely registered. The rat's body was being flooded with endorphins and her mind was clouded thanks to the nanobots driving her into a lust filled stupor. All she cared about right this moment was the wonderful tasting cocks and the constant supply of precum they delivered to her. It didn't matter that her own sons were stretching out her throat to an obscene degree as they drove down to fuck her stomach. This seemed right somehow. She couldn't comprehend of anything better. That's why she actually cried "no!" when Leonardo pulled himself out of her drooling muzzle and held her back from going down on Donatello. "That's enough foreplay. It's time for you to choose which one of us you want to be breed by."

The rat hesitated a moment as her intoxication died down and her senses returned. "Please, don't do this, I am your father." She pleaded only to get a disgusted look from her two sons.

"You were our father, now you are a slave to the Foot. Allow us to demonstrate your new position to you." Leonardo said as he nodded to Donatello. The taller turtle moved behind the rat and placed his hands on her strong thighs and lifted her up, simultaneously spreading her legs apart. She blushed bright red as her dripping pussy was revealed to Leonardo. Donatello started to move her up and down against his long shaft, soaking it with her leaking juices. She tried to fight back the urge to moan as her sensitive pussy lips were stimulated, but still one escaped. Giving in, she reached out and grabbed at his bulbous cock, bringing it in close so that it moved between her large breasts and allowed her to once again lick at it.

"That's more like it," Donatello said into her ear, making her shutter with joy.

Leonardo moved closer and pressed his dick up against his brothers. Splinter maneuvered his tip so that she could reach both, switching between the two constantly. They both tasted a little different, but wonderful in their own way. "Alright, since you wouldn't choose, we'll just both have to do it."

Together the two brothers lifted her higher so that they could enter her. "No! One of you would be too much, two of you will never fit!" She screamed as the two turtle cocks began to slide into her virgin snatch. Almost immediately they felt her hymen straining against their dicks. They showed no mercy as they pulled her down further, ripping through it. Splinter grit her teeth as they went deeper, stretching her wide. As bad as this was, it was nothing compared to what it would be like if they tried to shove all of themselves into her, but surely they had to know that wasn't possible. Then for the first time, she noticed Karai. The small woman's ass was stretched obscenely wide and a huge bulge could be seen in her belly moving constantly as Shredder thrust up into her, disappearing somewhere under her daughters ribcage. It was horrible, yet Karai's face was one of bliss. Her tongue was lulled out of the side of her mouth with drool dripping down. Her eyes were rolled back into her head as a huge blush seemed to be permanently fixed to her cheeks. With every movement, she squeaked and squealed in pleasure and her pussy dripped as she was sent into orgasm after orgasm.

Splinter let out another scream when she felt her sons prod her cervix. A second later they pushed her down sliding into her womb. The two turtles stopped for a moment, cherishing the feeling of being inside her most sacred place as they rubbed up against each other. Her chest heaved, moving her large breasts up and down as she couldn't help but also enjoy the feeling now that they had stopped. Unfortunately for her, they only paused for a few seconds and when they resumed they pushed her down with even more force and speed than they had started with.

Shredder watched as his enemy was raped by her own sons. Their cocks bulging out her belly and making her look pregnant as they got her ever closer to the hilt of their lengths. He grinned seeing the conflicted look on her face. There was pain of course as she got use to the size but beyond that, there was lust and pleasure. Soon the pain would be gone and only pleasure would remain, pleasure that would drive her mad and turn her into a nearly mindless sex toy. "She's getting close." He whispered into his daughter's ear as he pounded her rear with short, quick thrusts.

"I hope... that she's... not... the only one!" Karai said, every other word extenuated by a moan or gasp of pleasure.

"Worry not daughter, soon your punishment will be at an end." He said as the two turtles started to thrust up into the rat, making her tits bounce with each massive movement of their hips.

Karai let out a high pitch squeal of pleasure. "I didn't say I wanted this to end. It's just..." She let out a long gasp as she was rocked with another orgasm. Her pussy convulsed as it tried to milk the cock that should have been causing the pleasure. The feline felt her ass also respond, tightening around him. He grit his teeth and forced himself to not cum despite wanting to for the last two minutes. When she recovered enough to speak again she continued. "It's just that it would be a shame if Splinter broke before I had a chance to fuck her too."

"That's my daughter, always wanting to get her hands dirty. Don't worry, I'll grant you the final blow." He said grinding his cock against her.

Splinter let out a cute squeak with every thrust of her sons' hips. Nearly a foot and a half of turtle meat was sawed in and out of her obscenely stretched cunt. It was too much for her to handle now that the pain was gone. At least when she had that it kept her a little lucid. Now her mind couldn't concentrate on anything, she couldn't think or speak. There was only the cocks and the pleasure they gave. She wasn't even thinking of them as her sons now, they were two gods of pleasure and she'd serve them however they wanted so long as they wouldn't stop.

Leonardo and Donatello likewise were enjoying this more than anything they had ever experienced in their lives. The rat's pussy would have been tight for one of them, but with both of their cocks sandwiched inside of her, it was almost painfully so. She gripped them like a vice and it drove them wild. It only took them a minute to get to the point where they could cum. After that, it was a test of will between the brothers to see which could last longer. Leonardo figured it would be him since he had more training and control than Donatello. What he didn't take into account was that a super genius with lots of time on his hands eventually gets creative, especially when he has easy access to loads of parts from robots that can perfectly emulate humans.

After three minutes of constant humping, it became too much for the shorter turtle. Leo released a long moan as he began to empty his seed into the rats over stretched womb. Splinter's eyes rolled into the back of her head as she was nearly knocked out by her first orgasm. Her whole body shook as her belly swelled with each spurt of cum. Her fallopian tubes were stretched wide as his cum forced its way towards her welcoming eggs. It took nearly a minute for Leonardo to finally peter out. All that time Donatello didn't stop his constant humping. In fact, he actually sped up a bit using his brother's seed as lube. When Leo finally pulled out, the shorter turtle stumbled backwards dripping huge globs of sticky white liquid as he went before taking a seat on the floor to recover from the pounding he had given.

Now that his brother was gone, Donatello prepared to really let loose in the slut, but a gesture from Shredder stopped him. Instead, he bottomed out inside her, then picked her up and brought her closer to his new master and Karai. Once they were close enough, the human woman reached out and took Splinter's head in her hands, pulling her in for a kiss. "You may resume your work," Shredder said to the nerdy turtle, who happily complied.

Splinter and Karai moaned into each other's mouths as the two men pounded away into them with everything they could muster. Less than a minute later the turtle came, filling Splinter's belly up with even more of his baby making liquid, and driving her into another orgasm. A few seconds later Shredder let out a feral sounding roar and buried himself balls deep in Karai. Her eyes rolled into the back of her head as his hot seed shot into her intestines, up into her stomach, and eventually out of her mouth. Splinter eagerly accepted the delicious tasting feline seed, gulping mouthful after mouthful down until Shredder finally stopped. Donnie pulled out of Splinter after taking a few seconds to catch his breath, allowing a gallon of seed to pour out of her well stretched cunt onto the floor. Without his support, she collapsed into the puddle as she tried to recover. She was motionless for a moment until she heard Karai moan. She forced herself to look up, seeing the small woman who now had a belly as swollen as the rat's. She was being lifted off the massive cock, and its barbs were tickling her insides as she was freed from it. Once she was finally off, cum splashed down onto his crotch painting his bright red cock white. He lowered her to the ground next to him allowing her to get a steady footing before he let her go.

Karai took a couple of unsteady steps to bring her over to Splinter, doing her best to compensate for her distended belly. She placed her finger under the rat's chin and lifted her head up so they were looking eye to eye. "Are you ready to serve your new master now?"

"I will never serve him." Splinter slurred out trying to be defiant but sounding drunk.

Karai grinned. "I was hoping you would say that. I was almost worried that I wouldn't get my chance to breed you. Of course, there isn't much chance that you aren't already knocked up, but don't worry, I'll still give it my all." Splinter gave her a confused look, and the human giggled. "I'll let you in on a little secret. The serum that turned you into the sexy rat you are now came from me. It was derived by studying my ability to transform between a normal looking human and the snake I was mutated into. There's many uses for the serum, it all depends on how it's designed to effect its target, but for me, it's a bit different. When I used it, I unlocked the ability to fully control my body." Karai effortlessly transformed into a snake, though her form looked a little different than normal. It had broader, stronger arms that actually had normal hands, and the waist was flusher with the tail section of the body. Karai leaned in and whispered into Splinter's ear with a deep masculine voice. "Did you know that a snake has two cocks?"

Splinter cast her eyes down and saw Karai's slit opening, revealing two growing dicks. She could already smell the lust wafting off her newly transformed son's cocks. "You know what to do," Karai said in a dominating tone. Splinter looked at the snake for a moment, then leaned down and started licking the twin cocks, getting them nice and hard. As she worked, Leonardo and Donatello moved closer, their shafts once again at full size. Karai reached out and her arms began to extend, stretching and coiling around the rat's chest. Splinter whimpered as the arms tightened, pushing her large breasts up making them look even bigger. "Don't worry, you're going to enjoy this."

The sexy rat was lifted into the air a few feet. She looked down and saw the two turtles moving in and once again pressing their cocks together. Without even realizing it, she smiled at seeing that. She did notice that they weren't positioned the same way as last time. Instead of one being behind her and the other being in front of her. They would be on both sides of her. Karai began lowering Splinter, and when she was close enough the turtles each took hold of one of her legs and spread them apart until she was nearly doing the splits. When she was properly spread, Karai lowered her some more bringing the two turtle dick tips to the rat's well-muscled butt. Splinter bit her lip as she readied herself for them. A moment later their slippery cocks slipped into her virgin ass. She let out a long moan as Karai pulled her down over more than a foot of cum pumping girth. There was pain of course, but the pleasure seemed to overwhelm it. She didn't know how that was possible, but everyone else in the room did. The ninja master that had been such a hindrance to the Foot was dead, in her place an obedient cum dump was being made.

Karai stopped pulling the slut down once she had taken about two thirds of the turtle's length. He moved in, slithering closer as his twin cocks reached their full size. "They might not be quite as big or long as you're other sons, but they can do something special." He hissed as he positioned the dicks heads at her still dripping pussy lips.

The snake teased her entrance, tracing around it and soaking it with his precum. As he did, Splinter noticed a strange tingling sensation. Without warning he slammed all 20 inches of his twin cocks into her, making her moan. It felt so good to the rat, but she couldn't help but notice that it wasn't quite as intense as when Leo and Donnie had fucked her and it certainly wasn't as extraordinary as the two fucking her in the ass. That seemed to change the more the snake pounded her snatch. With each thrust, he seemed to feel bigger and warmer. It was strange since it didn't look like the bulge his dicks were forming in her belly was any bigger. "How are you doing that?" She asked between moans as she was bounced between the four cocks.

Karai grinned. "My precum has a very special kind of venom inside of it. It increases the sensitivity of your nerves and also tightens up any muscle or flesh that may have been stretched out. In other words, once I'm done fucking you, you'll be good as new." The snake increased his speed, slamming into the rat with abandon. He could feel his cocks rubbing up against the turtles through the stretchy membranes that separated them and found it made him even more turned on. Donnie and Leo also found the sensation quite pleasurable, though the rodent's tight rear was the main reason. Neither of them had thought that anything could be tighter than her pussy, but it was. In and out they went, creating a symphony of wet noises, grunts, and screams. Splinter came again and again. Sometimes it was from her pussy, other times it was her ass. Eventually, she stopped being able to tell what was causing it. She stopped being able to talk or even scream. All she could do was squeak and moan as she was drowned in ecstasy.

Finally, the three men decided they had enough and wanted release themselves. Karai came first. Both cocks unleashed a torrent of hot cum filled with more of the special venom. It coated her well stretched womb, triggering it to contract and try to mold itself around his dicks. Only the constant stream of seed and hard thrusts that shook her whole body kept it at bay. Splinter opened her mouth to scream, but nothing came out except a small squeal. After thirty seconds Karai pulled out, shooting the last couple of loads onto Splinter's chest, making her sensitive nipples tingle. When she was finally done, Karai reverted to her human form. She rubbed her belly feeling Shredders cum sloshing inside of her. She leaned in and licked the rat's nipple, tasting her own cum and making the rat jump at the feeling. A couple of seconds later she pulled back, licking her lips and feeling the tingling in them and her tongue. "Alright boys, now it's your turn."

The two turtles needed no more prompting and came immediately. Dual firehoses erupted inside the rodent, shooting hot seed straight up into her stomach. Her belly swelled even larger than it had when she was first fucked as their seed quickly filled her beyond capacity. The cum forced its way up her throat and began to pour out her mouth. It was the first time that Splinter had gotten to taste her son's seed, and it was delicious. Karai once again locked lips with the rat, getting her first taste of the turtles as well. She gulped down the seed, likewise finding it quite remarkable. About half way through, both men decided to pull out and deliver the rest of their load onto the rat. Of course, neither of them gave any consideration to what Karai was doing, so she was a little annoyed when Splinter was pulled away from their kiss and laid down on the hard, sticky floor. Both turtles quickly aimed their squirting cocks down at the rodent, soaking her fur from head to toe with their white steaming liquid.

Shredder stood up and looked down at the rat and smiled. Her chest heaved up and down as a glob of cum dripped off of her erect nipple. She had a content smile on her face, and one of her hands had snaked its way down to her pussy and pushed three fingers inside of it. "Get up rat." He ordered and after taking a moment to work up the strength, she did. "Do you see my cock?" She nodded her head and smiled. "What do you think of it?"

"It's perfect." She said in complete earnest.

"I want you to suck it, all of it." Shredder said with utter joy in his voice.

Splinter leaned forward, pressed her face up against Shredder's bright red length and felt the barbs against her fur. Then she gave him a lick all the way from the base to its tip, astonished that she had trouble getting the entire thing since it was so large. She kissed the dribbling tip, drinking down a mouthful of his precum. "It's what I live for, Master." She said as she opened her mouth and began to envelop the head of his cock.

To be continued...

That's it for part one, but there's a second part planned. Please leave a comment if you liked it.
