Summary
You and Raph have known each other for a couple years now, and as time has gone on, you've developed feelings for the turtle big enough to pick you up in one arm. Not that you've had the guts to tell him so, though- you value your current relationship of platonic cuddles too much to risk it.
Then, as spring looms over the horizon, you find yourself woken up from a cuddle session by something poking at your legs from behind.
(moving this out of the tags actually: hi this is the author after getting exactly 3 hours of sleep. i CANNOT stress enough that this is a hot accident and that (once everything's cleared up) neither party feels bad. while the possibility of it being rape is briefly discussed afterwards, it's made pretty clear that neither of them wanted or was trying to take advantage of the other and that neither of them holds what happened against each other. whether rape/noncon rustles your jimmies or not: ok 👍 that's not what happens here tho. it's just teetering on the hard-to-archive-warn line for me.)

Summary
Donnie isn't home anymore. Not really.
He was torn out of the Technodrome, but the Technodrome wasn't torn out of him, and honestly? They wouldn't have it any other way
OR
Donnie never truly leaves the Technodrome... or maybe the Technodrome never truly leaves him. This is Love. This is Home. This is how they were always meant to be.

Summary
"I can't differentiate my tones right now," Donnie said, toneless. "I'm irritated but not at you."
Though Leo could have had the decency to wear a shirt given what Donnie was going through.
Leo nodded, like Donnie wasn't eating dinner at eleven at night on a Wednesday and hadn't even bothered to heat up the dehydrated meat dish before consuming it. "What are you irritated about?" he asked, eyes flicking from the plate of food to Donnie's eyes. Knowing he wasn't going to eat it and likely debating how willing he was to fight over it.
As if timed comically his glasses slid a little down his face forcing him to push them back up with a harsh finger. "Having a body."
"Want to elaborate?" Leo asked, sliding his sandal from the inside of Donnie's right ankle up to his knee, "Is there something-"
The sudden jerk, churr, and dropping of his fork perked Leo right up.
A cocky grin spread over the slider’s face. "Oh you're horny," he whispered, closing his eyes and smelling the air.
Donnie clapped his knees together on Leo's pesky foot.
(Can be read as a standalone smut-shot!)

Summary
Leo struggled to catch Mike’s face as he moved around the kitchen. Mikey didn’t move this much when he was talking to his brothers, normally. But today, the ploy was obvious, and Leo had to give up trying to face him while talking.
“Dude?” Mikey started, finally looking right at him, “is something wrong?”
Leo glared at his brother, “no.” He bit out, hating himself for falling right into his brother’s trap.
“Hm, that’s interesting.” He turned around, the fucker, and kept talking while facing his pot. “I could—and ma—only if—Donnie—” the words broke around each other, giving Leo nothing to work off of except Donnie and a possible ultimatum? He wasn’t sure, and Mikey knew it. He looked over his shoulder, a smug grin barely hidden on his face, “You not gunna answer me, man?”
//
Leo starts to lose his hearing and decides his brother's don't have to know, that goes about as well as expected.

CaptainLeo:
@everyone
Whoever’s Mikey has been screaming in the ASMR voice channel for three hours straight, could you get him out?HasTheBraincell:
I’m so sorry that’s mine
I wondered why he was so quiet~~Electro~~:
THREE HOURS SHDHSJJSKI_Crave_Chemicals:
This is the third time in four days.
Please control your Mikey or I will have to use force~
In universe 2003, Donnie tries to experiment with the inter dimensional gun the 1987 turtles had given him. Instead, he accidentally creates a multiversal chat room for many different versions of his brothers, and counting.
It certainly makes life…interesting.TLDR: multiverse group chat between most iterations of the turtles. Starts with 2003, 2012 and 2018 but more are added as I go. 50% plot and 50% chaos.
*now includes the 87, mutant mayhem and bayverse boys!*Series

Summary
Purple chomped and yanked their head side to side. Their skull was grabbed and their jaw popped open. Another Hand squeezed their arms down and before Purple knew it they felt something squirt out of their tail.
“Seriously? Not you and the snapper!”
“Oh I'm going to pee myself! Great job! Super soldiers that can musk on their enemies!”
“Erg..”
Purple's breathing had rapidly increased. They released something else from between their legs. Something belonging in the trash corner of the cage with Blue. The Hand made another noise and this time Purple was dropped, landing on firm ground with a slight give.
“I was just moving you and your emotional support defect to a new, larger cage. And you poop on me? You poop on the great Baron Draxum?”
“Stop, stop, my sides hurt, ha ha ha ha HA!”

Summary
By eight thirty the lair was running on generator power and Donnie’s ears were ringing so loud he couldn’t even hear the baritone of the motor thrumming out in the open sewers. Note vibrating on the handle because no twin had returned home to rip it off with a roll of his brown eyes before depositing the original propane tank nearby. Donnie couldn’t hear Mikey’s voice as he asked about Leo, he couldn’t feel Raph’s hand as they brought him into the lair to warm up his frozen fingers.
Someone else moved Donnie’s mouth and made his vocal cords vibrate into the open air of their home. Someone else stood in the doorway of their father’s room begging their dad to get out of bed because Leo was missing. Someone else felt the world caving in because all the things that were supposed to be unimaginable were happening right now.
As if panic could knock back a respiratory infection Raph and Mikey hooked the TV up with Donnie’s numb help. The weather report was worse than they last knew. That blizzard that was originally projected to hit tomorrow by one in the afternoon would be here at their doorstep much earlier.

Summary
The Doctor and the Ponds stumble across some aliens in New York and team up with some mutant turtles to stop them from destroying Earth.
Meanwhile, some weeks earlier, the Turtles put a pause on their search for Karai when a blue box with some weird occupants appears out of thin air and whisks them away on an adventure.

"Raph stumbled and swore as the room- ship- whatever- shook around them and made a sound like a broken (possibly haunted) washing machine. He gritted his teeth as he tried not to fall flat on his face and noted somewhere in the back of his mind that his brothers and Amy and Rory weren’t fairing any better. You’d think the other two would be used to this by now, if they did this a lot. The Doctor was unfazed by all the commotion, running around the control thingie, limbs going in all directions like a drunk octopus as he piloted the thing. Assuming he wasn’t bullshitting them and they weren’t about to die horrible deaths. With their luck that was still a very real possibility."

Лідер йокай не збирається зупинятися на досягнутому та мріє завоювати решту континенту, щоб йокай могли тріумфувати, поки люди, які століттями їх пригнічували, корчаться під їхніми ногами.
Для того щоб реалізувати такий складний і амбітний план із захоплення світу, потрібно звернутися до науки. І знайти ідеального піддослідного. Хтось із людського опору, що кидає виклик величі йокай, ідеально підійде.Або
Барон Драксум виростив черепах, і вони занурили Нью-Йорк в апокаліпсис.
