The brothers stood in front of Don's invention that was covered by a cloth in his lab and Raph said irritably, while texting on his phone, "Ya gonna show us the invention, Donnie, or do we got ta beg?"
"Get off of your phone, Raph," Leo said crossly. "Is it that girl again?"
"Ain't yer business who I message, Leo, but yeah, it was her. She was tellin' me how awesome I am and how she can't wait ta see me tomorrow."
"As if you need more ego stoking," Mikey chimed in. "You already love yourself. Now you have two people loving you!"
"Hah, yer just jealous that I got someone," Raph said and smirked. "Because the only thing ya got is yer hand!"
"Guys!" Leo said. "Please. We're here to see Donnie's invention. Raph, please put the phone away. You can text Ali when we're done."
"Fine," Raph said, tucking the phone into his obi. "What do ya got, Donnie? We're all dyin' ta know."
"Your sarcasm is noted, Raphael," Don snapped. "But I assure you the invention will be a success this time and you'll be eating your words.
"Ya said that 'bout countless others…" Raph's phone rang and he took it out. "Hey, babe. I'm just with my brothers. Donnie has some dumb invention he wants ta…"
Leo grabbed the phone away from Raph and said, "This is Leonardo. Raphael will call you later. Yes, sorry. I'll tell him. Ali says hi and she's going to bed, but she'll dream of you, Raph."
Raph snatched his phone back and glared at his brother. "Fuck ya, Leo. Ya had no right ta take my phone away."
"Guys!" Mikey said. "Donnie's invention. You can argue later."
Rebuked, Leo and Raph stood, the latter with his arms crossed and a scowl upon his face. "Most of Donnie's inventions have been failures," Raph said. "Remember the personality modifier? It changed Leo into a totally annoyin' guy. Worse than now."
"Thanks a heap," Leo said touchily.
"Don't mention it," Raph said with a grin. "And it made me too nice ta fight and I was so sweet and adorable. I am, anyway, but made me a sap."
"I kind of liked you that way," Don said. "I reckon it was an improvement. Should have kept you that way instead of the insolent brute and ignoramus…"
"Watch it, Donnie," Raph snapped, his green eyes flinty. "Unless ya want my fists in yer mouth."
"Charming," Don said acerbically. "I can see why…"
"Not all of Donnie's inventions have been a disaster," Mikey said. "He invented the pizza dicer and slicer and Metalhead."
"I disagree," Raph chirped. "Metalhead nearly attacked me once after some virus got into his microchip and it was Donnie's fault, because he didn't update the antivirus software on the microchip. That bucket of bolts is a walkin' disaster. And it's evil. It put cockroaches in my bed and in my cereal. I didn't know until I was chewin' them and then I realized what I was eatin' after seein' more in my bowl. Ugh. Have ya any idea how fuckin' revoltin' that was? I was spewin' my guts out for hours."
"I remember that," Leo said. "You accused all of us and then you saw Metalhead doing it again."
"Hahaha I programmed it to do that," Don said, stifling a laugh.
"This time I'm gonna…"Raph growled, raising his fists.
"Easy, Raph," Leo said, placing a hand on his shoulder. "Don, why did you do that?"
"Because I got sick of Raph mocking me and my inventions. It's hurtful. I have feelings too. I'm not sorry. Raph has to learn to shut his big yap up. I feel kind of sorry for this Ali, whoever she is. She doesn't know what she's getting into. Poor girl."
"One more word 'bout her and I'm gonna break everythin' in yer fuckin' lab," Raph said, and bared his teeth. "Includin' ya. Now, show us yer invention, Donnie."
"I've been wanting to, but some jackass has been badmouthing me and my inventions," Don said coldly.
"Yer disasters," Raph said and smirked again. "Failures."
"They were tests, not disasters…" Don hissed.
Leo stepped between his brothers and said, "Okay. Enough. Don, reveal the invention."
Don took off the cloth. "This is my glue trap. As you can see it resembles the glue trap that humans use to snare rodents, but it's more advanced," Don said, choosing not to state that it was a latex based glue trap. He didn't want any awkward questions. Mikey would ask them and Raph, no doubt, would answer them and tell them all about latex used in a sexual way, going into tremendous detail. Leo would blush and then no one would give a shit about Don's invention. As always. 'Not this time,' Don thought.
"Why would we need a glue trap, Don?" Mikey asked. "How would it benefit us and we wouldn't catch rats. They're Sensei's, uh, relatives, so to speak."
"I think I know how," Raph said. "Ta catch the enemies. One of us would press the lever," Raph added, pointing at the machine's lever. "The gunk would fly and land on, for example, Hun, and he'd be all sticky and unable ta move. If it works and I say IF, because I doubt it will, might become one of our favorite arsenal ta use."
"Ding dong, Raphael," Don said, and nodded. "You actually got something right. I'm impressed. I didn't think you were capable of thinking. All you do is use your fists, you Neanderthal," Don added, still pissed about Raph teasing him about his inventions.
"I ain't stupid and I've had had it up ta here with yer jibes, Donnie," Raph growled, his green eyes blazing, as he lunged at his brother and knocked him backwards against the lever.
The machine activated and shot out its trap at everyone. All of them immediately got hit by the gunk that appeared to be color-coded to the mask they wore. "Gah! What the hell, Raph?" Don asked as he pushed him aside and shut off the machine, but that didn't seem to stop the gunk, because it spread out and started covering more of their bodies.
"Don, what is this?" Leo asked, trying to remove the gunk off of his body.
"This feels so weird," Mikey said, attempting to pull off the goo.
"Don, is this thing trying to kill us?" Raph asked. The gunk spread to Raph's groin, making him groan at the sensation, and it then removed his lower plastron. His balls and cock dropped, as they were exposed; both of them turning red and his cock growing erect at the pleasant sensations. The goo quickly stripped him of his gear as well, sending his obi to the floor, and the phone dinging from a text message from Ali.
"Is this… latex?" Mikey asked, as the slime proceeded down to his groin, exposing his balls and dick, turning them orange, and making him groan in satisfaction at the unusual sensation.
"Uh, maybe," Don said in embarrassment, as his cock and balls were exposed in a purple color.
"Why were you using that for your trap, Donnie?" Leo yelled, staring at his own exposed blue cock and balls.
"I thought it would help keep the enemies trapped, guys," Don said, as the gunk invaded his ass and made him gasp out loud. "Gah! It's entering places it shouldn't!"
"Oh, ya weren't fuckin' kiddin'," Raph groaned, as the slime also entered his ass, before moving down his legs to his feet and changing them. His toes had been compressed together by the gunk, so now instead of feet; he had what appeared to be boots, with grooves at the bottom of them. The ooze quickly did the same to Raph's brothers.
"Guys, I don't think we can beat this," Mikey said, as his arms turned orange.
"Fuck that! What is this doin' ta us, Donnie?" Raph asked Don, whose arms were covered as well.
"I don't know. It looks like they're giving us a new skin of some sort," Don said, through ecstatic groans "Feels really good."
"I'm ashamed to agree," Leo said, as his arms dropped and went over his head. Before he could say anything else, the ooze invaded his mouth, going down his throat and covering his head. The gunk appeared to be just a seething mass before it settled down to show off Leo's new head, completely covered in blue with a zipper for a mouth. The zipper was zipped up and Leo's eyes were covered by an extremely dark blue plastic, resembling something like a gas mask. Leo collapsed in ecstasy at all of the sensations, while his brothers' orifices were invaded and their heads were covered, before turning into the same thing as Leo. They all now had mouths with zippers, their eyes were all covered by a plastic eyepiece in a darker shade of their color and they all loved the strange sensations and collapsed in ecstasy.
After several minutes, Leo was able to regain his senses, but his mind was a mess. 'What is this? I feel so weird. I feel like I need something. I need,' Leo thought, standing up and shifting his gaze to Raph, who lay on his back and who was only just beginning to regain his senses. 'I need… to fuck,' Leo thought, as he went over to his red brother. Leo grabbed Raph's legs and lifted them off the ground, until his ass was exposed to him. With that in sight, Leo bent over, quickly penetrated Raph with his dick and started thrusting, making Raph wonder what was going on, but Raph did nothing to stop it.
'Feels so good. Fuck…,' Raph thought, as Leo kept thrusting in him. As this was happening, Don was waking up and thought the same thing. He looked up and saw Leo's ass, as he was bent over and fucking Raph. Suddenly feeling horny, Don approached the fucking pair and inserted his cock into Leo's ass, shocking the blue gimp, but Leo didn't stop what he was doing. Leo had already cummed into Raph's ass and felt like he could do it again. At that moment, Raph cummed as well. His dick was angled at himself, so all his cumming did was send ropey streams of the sticky substance onto his face and plastron and also drip onto the floor.
Mikey woke up and just like his brothers, he suddenly felt horny and a desire to immediately have his needs met. Gazing around, he saw his brothers' orgy and noticed Don's neglected ass, just waiting for his dick to enter him. Mikey ran off to Don and quickly plunged his thick rod into Don's ass, surprising him, but the purple gimp kept going and came into Leo's ass, while Leo and Raph both cummed again as well. Mikey thrust harder and faster into Don until he came, filling up Don's ass with his essence, and making no attempt to stop, because the sensations were amazing and he couldn't get enough of it. It was even better than pizza.
The orgy continued for several minutes and no one wanted to stop, as they kept fucking and shooting streams of cum into one another. Cum was pooled around their feet and Raph was drenched in it, but they wouldn't stop, unless something important made them.
"Boys, are you okay? I heard a loud noise. Did one of Donatello's inventions malfunction again?" Splinter asked, as he opened the lab door and looked inside. The gimped-up turtles stopped thrusting, as they all gazed at Splinter, who looked at them in shock, his mouth open and his eyes wide. After several seconds of awkward silence, Splinter fainted.
A/N I handled the first part of the story up until Raph knocked Don onto the lever and Epicenter did the rest.
