Dream Boy

Summary:

It was hypnotizing, sometimes April had to drag Casey from a place in the lair he was standing in too long because of how frequent she would catch him staring. It was another day in the dojo when Casey and April would watch the turtles' training sessions. Casey knew he wouldn't survive this one this time. Each spar, each spin of Donnies Bo staff, each flip and kick, always made his arms and legs look so refined.

Something was slowly building up inside him, and as it did, it was also simultaneously sucking the patience out of him as well.

Or

Donnie is huge, and Casey loves the size difference..

Notes:

Tmnt 2012 fandom went into hiding years ago but every time I rewatch the show it takes over my brain. Then I discovered Donatello like a couple months ago and then my third eye opened.

 

Idk why I never really shipped anything in the show bc, idk I never really thought about it. But anyway, hope you enjoy!

(See the end of the work for more notes.)

Work Text:

 

Nothing new ever happened up in the city anymore, with the kraang no longer giving them trouble, and shredder defeated, the boys spent their days lounging around. Along with their occasional pizza and patrol. It'd been two long years.

 

April and Casey were always visiting, there wasn't a day that went by where they weren't in the lair. Recently, Donnie and Casey began dating, a week ago in fact. The rest of his brothers were a little reluctant in letting Casey date Donatello. Overprotective and tough, they made sure Casey knew the terms that came with wanting to be with their little bro, and to Mikey, his big bro.

 

They never had to worry about long distance since they were always together. So much so that it gave Casey time to.....observe a couple of things.

 

Everyone was older, a little more mature, strong, and huge. It didn't mean that they didn't goof off anymore, if anything, they all goofed off a lot more now. The turtles specifically, more built, taller, and much more skilled than they were in their mid teens, but a certain turtle always caught Casey's eye.

 

Donnie. He always looked so smart with whatever he was doing or looking at. He could make eating a slice of pizza look like he was inventing a cure for the plague. Always so witty and quick with his solutions. It was something Casey really admired about him.

 

Not only that, but his minds been filled with something else too.

 

Donnie's body.

 

As inappropriate as that sounded, it was entirely true. Casey couldn't go five minutes without gawking at Donnie working on one of his machines or training in the dojo. Those muscles constantly subconsciously flexing with anything he did made him such a hunk in the hockey players eyes.

 

It was hypnotizing, sometimes April had to drag Casey from a place in the lair he was standing in too long because of how frequent she would catch him staring. It was another day in the dojo when Casey and April would watch the turtles' training sessions. Casey knew he wouldn't survive this one this time. Each spar, each spin of Donnies Bo staff, each flip and kick, always made his arms and legs look so refined.

 

Something was slowly building up inside him, and as it did, it was also simultaneously sucking the patience out of him as well.

 

Being so early into the relationship, the both of them were new to this sort of thing. Ever since April rejected Donnie, and Casey slowly caught feels for the hot turtle, they both had no idea what they were doing. Two completely different species just trying to figure out how to date each other.

 

Donnie had never been with a human, just like how Casey's never been with a mutant. This was all sorts of confusing, they've shared baby moments like some casual flirting and small pecks on the cheek. Only keeping their playful physical affection where no eyes were around, since Casey would always get a scary look from his brothers if he did any of that around them anyway.

 

Casey watched as the four turtles flooded into the dojo, sitting with his legs out and leaning back on both of his arms. April sat next to him on her legs with her hands politely in her lap, observing carefully.

 

"So, red, whaddya think they'll start with this time?"

 

"Dunno, but it doesn't matter to you anyway, since all you do is stare at Donnies face the entire time." April passed him a smug look, Casey rolled his eyes with no reply, a faint flush staining his cheeks. If only she knew he wasn't staring at just his face.

 

The boys bow to their usual sparing partners. Leo and Raph, and Mikey and Donnie. Splinter gives the signal to begin as the sounds of weapons clanging and crashing against each other fill the dojo. Casey pays attention to Donnie sweeping Mikey's feet while using the tip of his Bo staff to keep his little brother pinned.

 

"Gotcha!" Donnie grins, his cute little gap showing nice and proud. Which makes Casey's heart skip a beat. Mikey doesn't let Donnie relish in his tiny victory for long, he grabs Donnies staff and kicks it upwards, knocking it out of his hands. Donnie yelps and feels a cold chain around his wrist as he's brought to the ground in an instant.

 

Mikey laughs and blows a raspberry his way, "Aww yeah! Sorry to embarrass you in front of your boo, but a turtles gotta do what a turtles gotta do!"

 

Donnie lays on the ground in a pout, looking over at Casey flustered and embarrassed. Casey laughs, noticing Donnies quads flex in an impossible way, his muscles tensing as he uses them to get up off of the ground. Caseys face was a beet red as he kept....analyzing.

 

He wanted to touch them, like, really wanted to touch them. Casey was well built himself with all of the fighting and hockey and mechanic things he did, but nothing like Donnie. He was obsessed, it was so metal. He would make it his life mission to shower Donnie with compliments until he's so red his head pops!

 

Donnie noticed, but decided not to push it and finish his training, or, at least try. He didn't think he could keep it together after watching Caseys face flare up so adorable like that. Mikey finds him staring and gives Donnie a good smack upside the head. "Focus, dude! You can make goo goo eyes later!"

Donnie was busy doing repairs for the shellrazer when Casey barges into the lab. He discreetly closes the door behind him and approaches the wild Donnie with caution. Donnie, too busy welding the door back onto it's hinges, covered in grease with a large welding mask over his face, was too deep into his work to notice the rebel sneaking up on him.

 

It wasn't until Casey got close enough to hover over his shoulder and huff a breath of hot air into his ear to speak did Donnie nearly jolt out of his shell, "Hey, Donnie."

 

The turtle almost drops his torch, cracking his neck around to see just who had the audacity to--

 

Oh.

 

It was Casey. That beautiful, punk styled man. His hair fixed in a stylish mess, wearing his signature bandana with that flirtatious gap filled grin. He let out an admiring sigh as his face grew warm, staring deep into Casey's eyes. "Hey Jones." Donnie gives him a sweet smile, also flashing his gap.

 

The both of them think they're going to have a heart attack at each others looks. Especially with their faces so close together. A thin layer of sweat coats Donnies neck and shoulders. He wipes the excess sweat off of his forehead as he raises his mask. Casey backs up a bit to gather himself, both of the lovers trying to calm their reddening faces.

 

"What uhh....what brings you here?" The turtle questions softly, "I thought you were watching cris bradford with the guys?"

 

Donnie stands up to give Casey his full attention, the hockey player watches Donnie slowly rise from his knees, now completely towering over him. He tried not to short circuit and fall into Donnies arms right then and there, "Just thought I'd come and see ya." Casey steps a bit closer.

 

The mood in the air shifts, Casey bites his lip. "It's been awhile since we've gotten some time to ourselves." He coos as Donnie swallows. Playing the tough guy on the outside was easy, but on the inside, he was crumbling. His heart bumping a mile a minute, how was he going to hint to Donnie that he had some killer muscles and wanted to feel?

 

He had to turn on that usual charm he did that always got Donnie squirming. "Man, do you look good, kinda glad you don't really catch me staring at your smokin' biceps."

 

Well, that was one way to admit it, even if that sort of slipped out. 

 

Guess Casey Jones wasn't as smooth as he initially thought. Donnie freezes momentarily, trying to figure out if what he just heard was real. "M-my biceps? Heheh..." The ninja giggles to himself, praising himself in his own head. He did have good looking biceps, and if Casey really liked them, then his arms must be pretty nice lookin'!

 

The flush on Donnies face was practically permanent, offering one of his arms to Casey. "Wanna feel? Sorry, I'm kinda sweaty..." He says with a chuckle.

 

Casey licks his lips like a mad man. Going in for the kill, finally getting his fingers on the scales and getting a firm squeeze. April must be out of her mind to turn down a hottie like this. He takes his time, Donnie watching Casey's eyes light up, then suddenly go narrow.

 

"Ya know.....this ain't all I like about ya." Casey pulls him into a hug, his arms tight against his neck. His mouth pressed against Donnies ear as he whispers sweet compliments, like he's going down a list in his head.

 

Donnie busts a fuse, face as bright as a Christmas light. His knees fall weak and his hands instinctively go for Casey's waist, squeezing. His giant hands around him reminded Casey that he had a few more things he wanted to say.

 

"and I like how much bigger you are than me, total turn on. From your hands to your legs-- everything. You could throw me around with no problem and I'd love it." He says, "You're a little too gentle sometimes, it's okay to be a little mean, Casey Jones can handle it."

 

Casey flutters a flirtatious wink, "And don't get me started on that pretty brain of yours, I love the way you come up with solutions to problems in no time, super sexy." 

 

Pretty? sexy? Donnie could do nothing but listen and whine incoherent murmurs at Caseys teasing praises. Casey pulls him lower so he's not tip toeing to reach his ears, Donnie now bent over slightly to keep listening. 

 

Donnie didn't know how much he could take, one hand snaking down to touch his ass. Something snapped in him. One hand, then two, lift him off the ground to get carried over to the turtles desk. Donnie swipes whatever paperwork and research off of the desk so that it didn't get in the way.

 

He wasn't totally gone just yet, he carefully takes his precious lab beakers filled with who knows what and sets them aside to another place over on his lab table. He throws the welding mask aside, scrubbing a grease mark off his face as he climbs in between Casey's legs.

 

Okay, he didn't have to look that good doing this. Casey looks him straight in the eyes in surprise, when could Donnie take the lead like this, and why was it making Casey dizzy?! He feels one big hand slam right next to him on the desk so that Donnie could come closer. "Dammit Jones." He grabs Casey by the jacket with his other, speaking in a low, tempting tone, "you do some strange things to me."

 

Donnie pulls him in for a kiss, Casey reciprocating with no question, leaning into each others mouths. Soft grunts and heavy, rapid breaths through their noses were the only sounds that filled the lab.

 

Any part of each other they could get their hands on was felt thoroughly. From Donnie's arms, to Casey's abs, everything was touched. Cherished to its very core. They worshipped every inch of each other like the world would come to an end if they didn't. Slowly, carefully, passionately.

 

Taking their time, Donnie pinning him further and further into his desk with each kiss. Pressing his body completely against Casey, and he was loving it. Donnie's heavy stature on him felt like a giant hug to his heart.

 

They parted, but only to catch their breaths. Staring into each others eyes, surprised at how thing escalated this quickly, but neither were complaining. Donnie greedily takes Casey's lips again, placing both hands on his waist. Their kiss turned messy as they both scrambled to grab any other part of each other they feared they might've missed.

 

Casey suddenly pulls away, "didn't know you could get down like this, Don."

 

Donnies face grows hotter than it already was, rolling his eyes and snatching Casey by the chin. "Are you going to keep talking or do you need me to shut you up?" That came out a little more intimate that Donnie was hoping. He only meant shutting him up by thumping him on the noggin or blowing a raspberry in his face, but you know Casey, always taking it the dirty route.

 

"If it means you'll keep handlin' me rough like this, then obviously." Casey smirks up at the frozen in place Donnie. His big turtle hand covers his face, mumbling some incoherent bashful murmurs about not meaning it like that. Casey chuckles, pulling him in again. "Whatever, just keep grabbin' and kissin' me, yeah?"

 

Donnie grabbed him and pulled his face up to his neck, then, Casey feels a sharp pain on his collarbone. The turle had bit and licked a mark into Caseys neck, and Casey thinks he liked it a little too much. "Woah, do that again." He said dizzily. Donnie holds him again, stammering. "That-...yeah. That, I can do..."

 

Donnie takes his time running his teeth over the supple skin, sucking, biting and licking wherever he pleased. Casey leans his head back a bit more to give Donnie some more space. He whines, the turtle drowning himself in the adorable whimpers Casey was spewing, and the feeling of marking what he felt was rightfully his. He told himself he wouldn't stop until Casey begged, nibbling him purple and red.

 

The both of them hadn't payed any attention to the time, or how long Donnie had left his beakers full of mutagen and random chemicals out that were definitely supposed to be chilled in the freezer fourty minutes ago. Too busy loving on each other like they hadn't felt each other in years. Casey holds his face, staring deep into his eyes.

 

"Wow Don, this early into the relationship? You're bad." Casey laughs like they haven't been friends for decades. Even if that was a little different from being in a romantic relationship with your ex-rival instead of their old platonic one, Casey loved to tease. "You say that now after we made out on my lab desk?" Says Donnie, laughing and licking the taste of Casey off of his lips.

 

The hockey player flinches at how casually Donnie could say something as vulgar as that without becoming a blushing mess like he usually does. Casey leans in to kiss him again, the lab hot with their desire and lack of air conditioning.

 

"Hey Donnie, Mikey wants you to fix his--"

 

The two lovers flinch like cats, stuck in shock. A familiar voice strutting into the lab. There is no way this was happening right now. Raph and Leo had swung the lab door open looking for Donnie to fix Mikey's Cris Bradford tape for the tv. There they were, sitting like ducks. Donnie looking up at his two brothers with their jaws on the floor. Casey dropping his head from under Donnie and looking at them upside down.

 

Their brother, there, on top of his boyfriend, making out, in the lab of all places. Casey, too stunned to speak, could only blurt out: "Sup dudes."

 

Donnie stands up and puts his hands up in a panicked surrender. "We weren't doing anything malicious, swear!" But his swollen lips and crooked mask said otherwise. A couple hickeys scattered across his collarbone here and there. Casey sits up from the desk, facing his other ninja friends. His hair unruly, lips swollen, neck looking like it had been gnawed on, and jacket and shirt lifted. He stands next to Donnie with a pouty, yet guilty look on his face.

 

Raph cringes, "Right, and Leo isn't a space hero's nerd. We both know you were about to get down and dirty in here, have some shame!"

 

Both of their faces burn in embarrassment, "Really Donnie, I expected better. I could see Raph or Mikey, but you?" Says Leo. He tries not to snort out a laugh, but it's too late. Leo thought that this was too good not to make fun of. Raph looks at Leo, "Me?!"

 

"Cool it guys, it was my fault! Things took a bit of a heated turn-- but all we did was make out! Thats all! Promise!" Casey talks about it like it was just a casual thing you tell someone. All of their business, just announced like the daily newspaper. The red on Donnie's face had spread to his neck and shoulders. Casey, you evil, evil man.

 

Leo pipes up, very amused. "Yeah, with your neck looking like it was practically eaten. Jeez Donnie, you couldn't lighten up on him a little?"

 

"Shut up!"

 

"Okay, ew. Whatever you did, do it somewhere else next time!" Raph interrupts and chucks the tape at Donnie, the turtle catching it with ease. Leo wipes a tear from his eye, "Ahh that's good," he quipped, "but seriously, time and place Donnie."

 

"Ugh, okay okay I get it! Just go somewhere else!" At this point, there's steam coming from Donnie's ear holes. He's so embarrassed he doesn't know whether to attack his brothers or retreat into his shell. They finally leave with teasing laughs, Donnie could hear the echoed 'love ya bro!' from Leo as they walked out. They would never let him live this down, would they?

 

Casey scratches the back of his neck. Tensing up in guilt. "Aw man, I'm sorry Don, I didn't mean for it to go this far."

 

"Jones," Donnie says in a soft voice, "it doesn't matter, sure that was probably one of the most humiliating moments of my life, but-- it was worth it?" He looks at Casey with a forgiving look. The turtle feels Casey place another peck on his lips and squeeze the underneath of his biceps before walking out with a wink. "That was fun, finish whatever you're doing here and let's kick it tonight huh?"

 

Donnie rubs the embarrassed expression off before ultimately agreeing with a grin. As Casey leaves, he turns back to the shellrazer and tugs at his mask tails like braids, he looks down at his feet, giddy as ever. His face had betrayed him, still flushing, if not worse than before. It reached his shoulders as he smiled to himself like a high school girl that just hugged their crush for the first time. 

 

Donnie gives an in love, excited, low whisper to himself, "Awesome...."
