This was so totally fucked. 

Donatello was logical to the core; he was not prone to anything you could call  emotional . Especially anything within the assortment of feelings such as “ love ” or “ lust ”. He found them stupid, useless, and downright hilarious. 

Now he’s stuck laughing at himself. 

Donatello has  never  once touched himself in his life (he found it revolting - he had attempted, but it just made him feel sick). Now he’s considering it. 

Because of his  twin brother . It makes Donnie want to gut himself with a rusty corkscrew - he’s that disgusted with himself. Not to mention the reasons aren’t traditional nor pertaining to their turtle-instincts, which would’ve made a nice excuse. It’s not his twin’s body, while it is  nice , it’s certainly not because of that. It’s not his face, the way he moves, or  his scent . It’s not anything that’s explainable. 

It’s telling Leo what to do. The further the demand crosses the  line , that  line  that stands between siblings and  something , the more it sends that tingling rush through his body as he presses his thighs together and leaves a shaky smile on his flushed face. Leo is never one to cooperate, so whenever he does… it’s so, so  sweet . It’s addictive. And Donatello is now a severe, AA-meeting class addict. Watch him turn up to the next meeting. Humanoid turtle dressed in purple goes “Hi, I’m so addicted to bossing my brother around I’m considering death by alcohol addiction! Alcohol poisoning here I come!” (He’s never had a drop of alcohol, by the way.) Even just acknowledging the issue made him want to kill himself. 

That was only a slight exaggeration. 

Now, Leo doesn’t always do what he says. Often times he just openly mocks Donatello and teases him along with some overly friendly physical contact (that always seems to linger just a moment too long) and leaves Donnie fuming as he leaves the room. But that only adds more to the exciting thrill he gets when he forces Leo to his knees to apologize for stealing his stuff, and Leo actually  does it . 

It makes him, late at night, kick his feet in the air and smash his face into his pillow, screeching into it. 

Just as he was doing now. 

Not to mention a hesitant hand resting on the inside of his thigh, mere inches from the tail he hardly even noticed. He was seriously tempted. His body was abuzz- he was addicted to the feeling he got, the rush of power he got imagining the brother just as haughty as he was beneath him- and his head felt absolutely dizzy.

He still stopped himself, because, well, the idea of touching himself… just felt uncomfortable. Not to mention, it’s very unethical to touch himself to the idea of dominating his twin brother. He’s already breaking so many taboos by just imagining it, and he doesn’t want to add to his guilty conscience (honestly, he didn’t even know he  had  one of those. Turns out he does). 

He tossed and turned for what felt like hours, feeling sick at the sensation of the slick between his thighs, and as his mind got cloudy once more, he decided to give up on the idea of sleep. He decided instead to distract himself with the lovely thing that was technology. 

Tinkering on the wires of a  totally  non-lethal high-grade titanium alloy weaponry with high-grade explosives in it, his mind finally felt at rest, filled with the typical things; what to build, what to upgrade,  if he committed murder how would he get away with it  (IF, and by the way, he totally would get away with it), if he should finally make a stupid coffee maker for his room, and geometric equations that would give a calculator a run for its money. 

Much better. 

That is until he started falling into microsleep while working with his blowtorch, the time now surely 3 a.m., and he realized if he was going to keep working he probably has to get some sort of caffeine in him unless he wants to burn off an arm. In all honesty, he was more of a tea guy, preferring the diluted, soft, warm, and soothing taste of it, but he needed caffeine to be the inventor genius he was. Inventor geniuses don’t come from getting full nights of sleep, they come from coffee addictions, you know. 

Turning off his blowtorch and tossing his welding mask, he shambled over to the kitchen (pulling on a purple sweatshirt along the way), hoping that the resident insomniac wouldn’t be in there or else he was going to implode like a supernova. Whether from agitation formed by his exhaustion and empty social battery or shame from his thoughts and half-formed fantasies, he wasn’t sure. Possibly both. 

Likely both. 

But, as Lady Luck will have it, the red slider who stalked around the house like a phantom during the night had chosen his haunting place to be the kitchen. It made Donnie feel like smashing his head into the kitchen cabinets. If Leo spoke to him, he just might do it. His twin was chilling on a countertop, surfing through his phone as his hand robotically brought some sour-onion-something-looking chips to his mouth from a crinkly bag, dressed in his blue pajamas and a stupid nightcap. 

Though the shame that came with seeing his twin after all the vaguely sexually related thoughts he had was burning red-hot. He refused to look at his twin as he scrambled to find his purple mug, hoping Leo wouldn’t try to start any sort of conversation. 

“Can’t sleep, Don-Ton?” 

His voice was certainly pretty, even with that sleep-deprived rough edge to it. 

He smacked his head against the cabinet (getting a concerned “woah, you okay?” from his brother). 

He slowly turned to look at Leonardo as he moved to make his coffee on autopilot. 

Donatello, in his in-depth 2-word list of useless emotions, had also included “love”. He wasn’t going to elaborate on it whatsoever, because that made him feel even more disturbed by himself than the lustful thoughts he was having. 

Donnie spoke with some hesitation, something that was out of character for him. “It’s not that I can’t. I’m choosing not to.” 

Leo looked at him and lifted a brow. “I don’t know about that. Don’t think I haven’t heard you messing around with that blowtorch of yours every hour of the night for the past few days. You’re going to burn the house down at this rate.” 

Oh, haha, that’s because I’m thinking about pushing you down on your knees and can’t sleep because I’m so turned on by it. Funny joke. Ha. Haha.

Along with the nearly hysterical voice in his head, he silently hoped that that blowtorch burns him down with it because he should not have found that teasing tone attractive, and  yet  he  did  and he wanted to hear even more. More -  more , like how he’d love to hear that voice whine and–

No . Heavens above he hopes he goes burning down with it. 

Leonardo, curse him, must’ve noticed his delayed reaction because he walked over all kind and worried and probed for an answer, an explanation for Donatello’s sudden mutism. “Donnie?” 

Donatello gave Leo an awkward half-smile. “Just working on something. Something amazing, by the way, thank you.” He couldn’t help but shove Leo out of the way as he reached to grab his freshly made coffee from the machine, mentally thanking random gods from various religions for making the time pass less painfully slow and more just excruciatingly slow. Now having what he came here for, ignoring the way it was searing his fingers, he moved quickly to escape. 

Of course, Leonardo, like some creature from heaven and hell, stopped him, probably freaking out that Donnie might be falling into some sort of depression again. Donatello wanted to kick himself in the face when he found himself staring at Leonardo’s lips which were suddenly not that far away. He pushed Leo away, his brother now at arm's length, and found himself out of breath. 

He was panicking a little. 

Leo now even looked  more  worried and it was clear this tactic was not working. 

Donnie cleared his throat, the hands he used to shove Leo off now gently dusting off his shoulders before going back to rest at Don’s sides. He gave Leo a casual, prim smile. “Just can’t sleep, Leon. I’m going to go work now. Night.” 

He hoped Leo wouldn’t notice he just contradicted himself as he walked off, leaving Leo in the kitchen with his stupid onion chips. 

He couldn’t help but have a bad taste in his mouth, knocking the blowtorch off his desk with a clatter as he sat down in his swivel chair with a scowl. He was being ridiculous. Now he was acting like some sort of whackjob because he’s into his brother. Oh, hahaha, doesn’t that make  him  a whackjob? Man, this is just  great . 

He grabbed the welding mask and banged his head against his forehead, the dull pain resetting his system and allowing him a clear mind. He carefully set it down, “ Sigh ,” and leaned back into his chair. 

Just act like nothing is wrong (with him). Fun. 

In the morning, he woke in an awful mood and a crick in the neck like no other. That’s what he gets for falling asleep in his chair, anyway. 

Though it did make him feel like committing some kind of homicide, he decided against the temptation. Oh, boy was he tempted. 

His day started with some of Mikey’s somewhat undercooked pancakes (the batter was still partially liquid inside), nevertheless eating them all even though the texture made him feel like coughing up a lung, then brushing his teeth, getting a cup of coffee, and back into the comfort of his lab. No sightings of any red sliders, so all was well and good in the world. 

That was until Leo decided to bless him with his presence at midday, portaling into the air and onto his desk, falling off of his desk, and going rolling all over his floor. 

The metal scrap he was working with creaked under his grip. 

He stood over Leonardo, seething. “Leonardo. What are you  doing  here?” 

Leo gave him an unsure, slightly terrified smile. “I guess I just decided to…  drop  in?” 

Donatello dropped the scrap metal immediately and decided the logical course of action was to tackle him. For a few moments, the two brawled - more playful, than anything - before Leo was able to roll free, the two left breathless. Donnie stumbled to his feet, hands on hips, a little less irritated and a lot more exasperated. “What are you doing here, Leon?” He repeated, acting as if he wasn’t seeing Leonardo splayed out before him as he towered over him just as he loved to imagine. 

Leo gave him another smile, this one far more confident than its predecessor as he stood up, dusting off his knees. “Just checkin’ in on ya, bud.” Enjoying his two-inch height advantage, he leaned upon Donnie as he placed an arm across his shoulders, seeming to be just chipper. Donatello scowled, immediately pulling away from the grip – his skin feeling far too warm from where Leo touched him. “Alright. You’ve checked in. Shoo, shoo.” He swatted and Leo, mechanical arms coming from his battle shell moved to push his twin out the door. 

Thinking this was a signal to stay, Leo did a fun little flip over the arms and grasped Donatello’s shoulders, guiding his brother over to his desk. “C’moooonn, show me what you’ve been a-makin’!” 

Donnie stared in disbelief. “ You  want to know what  I’ve  been making?” 

“Why of course, Donnie-boy!” 

Donatello pulled away from Leo’s grabby hands, looking at him with clear doubt, but also was very clearly excited that Leo was taking an interest in his work. Oh, god. That “love” thing again. He felt like this was a big ol’ prank, and it likely was - some Raph-sized beach ball (eugh, shivers!) doomed to come bumbling down his hall, but he was maybe a little too happy about spending time with Leo to care. Sitting in his chair, he gestured for Leonardo to come closer, allowing his brother to loom over him. He pretended not to notice the hand Leo put on his shoulder, one that was maybe just a little too close to the soft curve of his neck. 

“An ex-new engine for the Turtle Tank,” he began. “You see, I wanted to make a new engine for the Turtle Tank… but it’s way too powerful. I decided for the safety of the civilians I should not allow any of you to drive with it. But possibly into a motorcycle or something I could use, as the responsible one, yes.” 

To his surprise, Leo remained quiet throughout his digs toward his brothers. He didn’t even loudly protest against the ‘responsible one’ comment. 

Was Leo actually listening?

His face felt a bit hot for some reason. Was it him, or had Leo gotten closer? He could feel his breath. It was warm. It also smelt like peppermint and coffee. 

His face was feeling hotter. 

Talk.  Speak! It’s silent right now! 

“I made it out of…” 

Even as he rambled about the parts and inner workings, Leonardo remained stoic, listening, or at least pretending to listen, to every word. Leo’s hand seemed to be moving lower. Was it? Is this some weird vaguely sensual hallucination caused by sleep deprivation? Had he finally kicked the bucket? Gone clinically insane? 

He paused, wanting to test it. “...Ah. I forgot what I was saying. Where was I?” An obvious lie, but…

You can imagine how his eyes went wide as Leo repeated exactly what he had been saying right back at him. Final straw. Donnie’s heart was beating out of his chest. He always loved when his family showed interest, especially Leo, but whenever they did it became  too much  for him. He quickly kicked his chair out, going spinning backward, letting out an exaggerated “ Siiiigh .” (The spot where Leo’s hand was still alive with the sensation, his heart throbbing painfully in his chest.) 

He looks at Leo deadpan. “Alright, Leon. So what do you want? To build you a TV? Remote's broken and you don’t want dad to know? Etc, etc. What is it?” 

Leo's expression was aghast, putting on some poor falsely accused charade. “Whaaat? I don’t want anything. Though a TV just for me would be nice… but no! Nothing, I swear.” 

Donatello snorted, dubious. “ Scoff . If that’s true, you must be a clone. Possibly a robot programmed to have your appearance? Hmm. Maybe a demon birthed from a magical symbol? Mystic shenanigans?” 

“Do you really think it’s so crazy I’m interested in what you’re making?” 

“... Yes ?!”

Leonardo stared at him, flabbergasted. “I should be offended by this, but I won’t be, because I’m your favorite brother.”

“Mikey’s my–”

“Tut, tut, tut. Shhhh.” Leo pressed a finger to his lips, hastily shushing him. “I know, I know. You’ve been too shy to admit it, but I know.”

Donnie was three seconds away from biting off Leo’s finger until he realized once again how  close  Leo was and the fact his finger was on his  lips , leaving him embarrassed. Embarrassed. Donatello. Embarrassed. How do those two words even fit together? You’d only ever find those two words together in a fantasy novel because realistically, it just couldn’t happen. 

Yet it was. Donatello was flustered. He bit his tongue so hard that he tasted iron in his mouth. 

He swallowed, throat feeling dry before speaking. “‘Nardo, if you don’t move your hand before I count to five, I’m going to bite it off. One. Two–” 

Leonardo pulled away his hand, shoving it far behind his back and gazing at Donnie like he were some moody circus lion he had to tame. Which may be a pretty good description of the situation. Spare for the taming part. Just the part where he is like a lion ready to bite this idiot’s head off. 

“ Good boy , Leon,” Donnie said in a low voice without much thinking, pushing his chair back to his desk. Then what he said finally registered, sending alarm bells through his head. The  line  was being fucking toed right now because that was  weird  to say. But god if it didn’t send shudders up Donnie’s spine, the affectionate words already comfortable on his tongue. 

Leonardo was silent, and Donnie was too scared to look back, pretending to be working on the engine that was already pretty much completed. 

When he finally got the confidence to look back, Leo was gone. 

Ah,  fuck . 

Gutting himself with rusty corkscrew was suddenly sounding a lot more pleasant than it should’ve. 

Donatello didn’t see Leonardo again until the next day, during which he was met with avoidance. Dodging eye contact - which was fine, Donnie didn’t love eye contact anyway, avoiding physical contact - which was also fine, he didn’t love physical contact anyhow, and not speaking to him - which was also, also fine because he didn’t love talking all the time either.

It was also fine because Donatello was sure it was because of what he said because it had way too much of an almost sexual undertone, which was nasty and just  vile . So Donnie didn’t blame him for it. Plus, Donnie had been acting way too irritable lately and maybe Leo was just mad about that.  

It was fine even on the second day. Donnie understood. 

And the third. Though it’d be good if Leo would just talk about it. 

It had gone from  fine  to  okay  on the fourth. Was saying ‘good boy’ really  that  bad? It really wasn’t, right? 

And on the fifth, he was just annoyed. Okay. This is too much. 

So he found himself lurking around the lair post-2 a.m., sneaking like some predator prepared to ambush its prey. And he was, quite literally, about to do just that. 

When he spotted the familiar green-and-red ghost of the home going into the kitchen, he came out of the dark with a vengeance, following right behind a few minutes later. When he grabbed Leo’s arm, he was met with a near-deadly attack with a butter knife. The knife, which Donatello dodged, was then embedded into the wall, leaving both turtles staring at the damage shortly before shrugging it off. 

Though when the two made eye contact, Leo went all shades of pale, looking as if he had just seen the devil himself or something. 

“Leo.” Donnie tightened his grab on his brother’s arm, noting the way Leo tried to slide his way free. While he found the way he squirmed delicious – focus, Donnie – he had a goal in mind. “What is  up  with you?” 

Leo harshly struggled, freeing himself from Donnie’s vice-like grip. “Geez, Donnie. That might bruise. You know we all bruise like goddamn peaches.” 

Donatello looked at him humorlessly. 

Leo refused eye contact, opting to make some romantic eye contact with the row of hanging pots and pans that hung above the island in the center of the kitchen. 

“Leonardo.” Donnie’s voice was clear, a warning. 

Revealing the cause for his butter knife, Leonardo shoved a buttered piece of toast in his mouth. And then he spoke. With his mouth full. “Acfuhyah Iah sheme tuh–” “Shut up. I’ll wait.” 

The two sat in tension-filled silence spare for the sound of Leonardo’s crunchy chewing, which was very obviously purposely slow. 

Almost a whole minute or two later, Leonardo finally swallowed, finishing that stupid toast. Donatello looked at him venomously. “What is wrong with you.” It was more of a statement than a question, honestly. 

“Oh, you know. This and that. Beauty and skill, talent–”

“Leo.” 

The red slider was sweating, his eyes looking from either exit on the sides of the kitchen, wanting an escape. However, Donatello would not give him that opportunity, standing squarely in front of him, his gaze pinning his brother down. He did get a certain enjoyment – seeing Leo worrying his lip as he fidgeted with his fingers, swaying back and forth with nervous posture. But more so, he was nervous. Did Leo find out somehow? About these thoughts? It was impossible, he knew, but Leo was smart, as much as he hates to admit it – he wasn’t as good with emotions as Mikey, and he wasn’t as intelligent as Donnie, but he had a certain cunning aspect of him. He always knew people's intentions. 

“Dee, c’mon…”

“Don’t  c’mon  me! Tell me, Leonardo Hamato.” Full name bomb, dropped. 

Leonardo flinched back. 

Ugh. It was so awful how much Donnie was enjoying this. He sort of wanted to… tease him? No. Focus on getting the information. 

“Why are you avoiding me, ‘Nardo?” He asked almost sounding sweet, switching gears like to that time when Splinter stole the Turtle Tank. You catch more flies with honey than vinegar, amiright? 

Silence overcame the room once again, yet this time no chewing interrupted it. It was just quiet, only the faintest sound of their breathing, and the sound of Donatello’s circulation and heartbeat in his ears. He noticed that Leonardo was breathing faster than normal – not fast enough to be a panic attack, but quicker than usual. He knew this because he studied all of their vitals religiously (out of worry, wanting to make sure his brothers were always okay, not that he’d ever admit it). He could tell from the rise and fall of his chest. 

He also noted that Leo’s plastron was exposed. He had unbuttoned a few of the top buttons (and also wasn’t wearing that stupid cap). This seemed important for some reason. 

Right. Because Donatello’s a freak whose attracted to his twin brother–

“Because of what you said.”

Who deserves to be punched in the face. 

Donatello’s face fell, suddenly feeling nauseous. He might be sick. He felt like his heart just  dropped . Not actually though. That’s impossible. 

Leonardo’s face was twisted, red, and with his lip curled, crossed arms – defensive. 

“Wh… what I said?” Donatello echoed, sounding weak. 

It was quiet again until Donatello took a step back, and then another, until he was up against the island, luckily being short enough that his head didn’t bang against the pots and such. He might gag. Are emotions meant to be this strong usually? Is this self-hate? He was not used to the feeling. Arrogance was second nature – first… first nature? – anyway, he was almost always self-assured. 

But he was very ready to shove his head down the next sink disposal until Leo spoke again. 

“It turned me on. I’m sorry.” 

…What?

All of those painful emotions vanished to just pure shock. Wuhuh? What? Did Leo just speak another language? Pig Latin? Old English? 

“I– I’m really sorry. I just– I’d been feeling that way for a while, and I guess I just realized it then. I don’t know why I’m feeling this way towards you— you can hate me if you want— it’s not just, like, uhm, lust– I, I don’t know… y’know, I… love… uh,” 

Hyroglifics? Hyroglifics in verbal form? 

“Donnie…? Please speak to me, Dee.” 

Finally, his twin’s words sinking in, he was once again shocked by the scene in front of him. Leonardo had sunken in on himself, crossed arms with downcast eyes, still biting at his lips with his nails digging into his arms. He had never seen his brother look so  scared . It felt like Donnie just had a bucket of ice water dumped on him. 

It made him feel sympathy. He understood his feelings. He also felt bad, because he  loved  Leo, in more ways than one. 

But he was also getting this horrible sense of sadistic joy out of it. 

Without even thinking, his voice came out. “Leon.” 

Leo perked up, looking more and more like a scorned dog. 

“Are you sure?” 

What am I doing ohmygod what am I doing?

Leo looked confused, slowly lowering his arms. “...Huh?” 

“Are you sure? I mean, we’ve got to check.” Suddenly, Donatello was closing in on Leo, finding his arms on either side of him. And watching his brother’s face flush amidst confusion and helplessness, he felt himself shudder.  Yes .  This is it . 

Leonardo spoke hesitantly. “What… what do you mean?” 

With confidence Donnie was sure he didn’t have, his hands moved from caging his brother to deftly unbuttoning each of those little blue buttons, revealing the plastron he’s seen every day. Yet somehow unbuttoning those stupid Scrooge-looking pajamas made it feel a lot more special. 

Leonardo still stood, paralyzed, as Donnie pulled the shirt entirely off his person, tossing it to the floor. His hand slowly moved over the plastron, the texture familiar to him. He had noticed it before, but Leo’s plastron frames his collarbones perfectly with how it curves outward. He moved close, ready to press his lips against it, before pausing. “Is this okay?” He whispered, his false bravado fading by the moment. 

Leo let out a meek, breathless little “ yes .” 

The false bravado became very much real and back in full force as Donnie pressed his lips against the muscled, slender curve of Leo’s neck, not even caring about the  line  that had already been crossed hundreds of times over in the past few minutes at this point. He pinned Leo’s hands to his sides, enjoying every little shiver that resulted from every butterfly kiss Donnie placed on his neck. 

It was meant to be, like, attractive, but Leonardo only giggled. Leo quickly explained with an “it’s ticklish,” before Donnie sucked on his shoulder, making Leo interrupt himself with a deep intake of breath. 

Soft-shelled turtles always love to bite , Donnie thought before his teeth dug in, Leo letting out a pained, yet pleased, gasp. It made Donatello’s body feel as if it were on fire. Once he tasted iron, he knew he’d be addicted to this - especially after he pulled away, seeing the red and purplish mark left behind. It made Donatello lick his teeth clean of the taste of skin and copper, before moving to bite along Leo’s neck again. 

When his second newly formed addiction was finally sated (the first being imagining scenarios, just like this), Leonardo was left with nearly a dozen bitemarks that left a painting of blue, purple, and red up his neck and down his shoulders. Not once did Leo protest, only letting out sighs that sounded like music to his ears. 

“Good so far?” 

Leo mutely nodded. 

That feeling of control surged up again. “Say it aloud.”

It felt like a beast who only got a taste of an appetizer as Leo spoke with a wondrously bashful face, “yes– it’s good. It’s really good.” 

Though he was met with a surprisingly soft feeling as he watched an almost goofy smile overcome his brother’s face. “I–I did not expect this when coming for a midnight snack…”

Donatello braced his head against Leo’s plastron, letting out a small huff of laughter as he released Leo’s wrists. “Yeah,” he murmured, leaning into the sensation of Leonardo’s arms going around him. 

The moment was warm like that of hot chocolate and tasted of the same sweetness.

Though time waits for no one, so it swiftly ended when Donatello pressed a kiss to Leo’s plastron, then moved up to press a kiss to Leo’s lips. 

Leo jumped but immediately kissed back, unable to help but lean backward as their plastrons clinked together. The kiss, at first gentle, became hot and forceful as Donatello held Leo’s face, the other gripping at the ridges of his spine through his softshell. Their tongues pushed against each other, teeth roughly meeting again and again. 

Leo pulled from the kiss with a gasp, already out of air, but was forced into another as Donnie kissed him more and more, leaving his twin dizzy and panting when he finally pulled away. He wiped his mouth with his wrist, loving the just  dumbfounded  expression on Leo’s face. “I like you too. Like that,” Donnie says in a short confession, not good with words or confessions, not even giving Leo the chance to process it before he started to pull off Leo’s pants. 

They were off within the second, Leo’s head still unable to catch up with their progress, still short of breath. He couldn’t help but find it cute. He picked Leo up with a bit of difficulty, setting him on the counter and spreading his thighs apart in one motion, seeing the tail between them – red and puffy and already slick. From that little amount of kissing? 

…Actually, Donatello wasn’t all that much better. 

It was more similar to his than he expected. The tail was long– and thick, the cloaca at the very top near his crotch within sight. He actually… didn’t know what to do at this part, in all honesty. But he should start slow, right? 

He pressed a finger against the slit, eyes going wide as it twitched and Leo gasped. That was lewd. His own face was surely red – he looked up to Leonardo, whose face was surely brighter than his own, with pupils wide staring down at him. 

He took a deep breath, slowly pushing his finger into the cloaca, the tight heat pulsing around his finger. Leo let out a– a churr, making Donatello’s body feel way too hot. For a moment he thought about how sanitary this all was, whenever he was nervous he got too self-aware (was he even doing this right?)– but was startled out of it by the scent. How hadn’t he noticed it before? It was starting to smell good – intoxicatingly good. A second finger pushed in, moving in slow scissoring movements before pressing against the top of the slit. Every sound Leo made sent his insides throbbing, feeling his tail curl against the inside of his thighs. He could feel his own slick staining his shorts, but he didn’t care much. 

The scent– it was making his mouth water. He couldn’t help himself as he leaned down, pressing his tongue against the slit. He flattened his tongue, moving slowly, but he hardly even get the chance before Leo’s dick dropped down, making him flinch back and pull his hand away, surprised. 

Leo was a bit sensitive. That was… good. That was good. 

The inner scientist in him couldn’t help but be entranced about how Leo’s looked so different from his own, but he quickly shut that up because Leo was looking a bit teary-eyed at this point (he loved it, though, honestly). “Mind if I..?” He said quietly, a hand hovering over the dick that was drooling from the tip, looking red and swollen. 

Leonardo nodded furiously, moving his hips up to meet the palm of Donatello’s hand. 

Something came over him. 

“No.” He said, giving Leo a harsh glare. “Stay still. Or I stop.” 

Both brothers froze in their tracks. 

Donatello panicked, wondering if he screwed everything up, but found himself relieved when Leonardo slowly lowered his body, giving Donnie back full control. Exactly. This was perfect, he thought, a shaky smile overcoming his face. His hand slowly wrapped around Leo’s base, getting sick satisfaction from the way Leonardo winced, churring, expression contorting. The hand moves slowly, eyes unable to look away from studying Leo’s face. Leonardo’s naturally cocky expression melted from pleasure was something he likely wouldn’t see often, and the fact that just his  hand  was doing this made him feel certainly  something . He leaned forward, pressing a kiss to the tip, analyzing the reaction. 

Leonardo let out the loudest churr yet, clutching the countertop to stop himself from jolting his hips forward. Donatello’s smile went wide, unable to help himself from licking in a long stripe from base to head, watching as Leo’s entire body shuddered. 

“D-Donnie,” he called so weakly. “You’re such a jerk.” 

Very Leo , he thought affectionately. 

His other hand joined, both moving to stroke him from altering directions as Donnie’s tongue moved to fill in the rest of the gaps best he could. It left Leonardo gasping, his hands barely able to stay still as the knuckles went white from his grip. “Donnie!” He exclaimed, squeezing his eyes shut with a bitten. At every movement, a churr or whimper responded, Donatello barely noticing when he himself dropped down in his shorts, the black, skin-tight shorts uncomfortable. Donnie barely acknowledged it, focusing more of his energy on making Leonardo just  squirm . 

Every lewd noise he received made him feel more and more  alive , every tearful gasp just making his body throb. Each pump of his hands made Leonardo’s body flinch, a suck on the tip sending Leo’s head lolling back with a cry muffled by the hand he held over his mouth. It was amazing, how he was trying so hard to remain  still , to remain  quiet . 

Leonardo suddenly grabbed Donnie’s wrist, looking at him with wet eyes. “W-Wait, wait. Wait. I’m going to… cum. I don’t want to… uhm, yet.” 

"Oh." Donnie paused, pulling away his hands, getting flustered all over again. This was all quite sudden, wasn't it? 

Leonardo's eyes went down his body, hoping from the counter and stumbling, his knees wobbly. Donnie went to balance him, but he was promptly shoved off, met with a face of absolute humiliation. It seemed Leo was not entirely pleased with how the night was going, but he voiced no concerns, so Donnie supposed Leo didn't mind all that much. 

He pushed Donatello against the counter, making him snort. "Really?"

"Really. Jerk." 

Though he couldn't help but watch, hypnotized, as Leonardo slowly sank to his knees. Oh.  Oh . Donnie pressed a hand to his face, looking around at the kitchen doors and realizing  literally anyone could just waltz in . He's lucky Leonardo was smart enough to try to keep quiet. 

Though maybe he kinda liked that someone could walk in, seeing Leo on his knees in front of him. 

Not  actually , of course. Just the idea of it. It was  hot . 

He was distracted by his thoughts when he felt teeth pull down the zipper of his shorts. He squeaked, the sudden cold air making him shiver - unable to help himself from squirming away as his dick was pressed against Leonardo's face, painting a lewd picture. "Euhm," he mumbled. "Sorry." 

"It's okay," Leonardo said softly. It felt like they had somehow swapped roles. 

All semblance of thought was instantly destroyed upon Leo's mouth wrapping around his head, making Donnie let out an obnoxious churr along with the most perverse whimper. Oh, god. He will never live this down. 

Leonardo hummed, making Donnie twitch, his arms gripping at his sides - unsure where to put them. 

Despite his first reaction, thankfully, Donatello was naturally rather quiet. That didn't stop Leo from making him churr over and over again as his tongue and mouth wrapped around him, making the soft-shelled turtle brace himself upon the counter. He felt like his world was going off-kilter, meeting eyes with Leo,  on his knees on his knees on his knees  making him feel just faint.

It  burned , that's the best he could describe it. The pleasure made him feel like he was on  fire . Combined with his scorching desire, he felt the most alive he had in his life. 

Control . 

He needed control, or he was going to go crazy. 

He moved instinctually, pressing a foot against Leonardo's dick and pressing it against the slider's thigh, watching as Leo's pretty eyes went wide and he pulled off with a wet gasp. 

Donatello's mouth felt stiff as he spoke. "Who told you to stop?" 

Despite his authoritarian tone, his hands shook. 

"Jerk." He heard Leo murmur again, but he still found his twin's far too-hot mouth wrapped around him once again. It made him lose focus, but it wasn't long until he pressed back down onto Leonardo's cock, where he could  feel  the trembles go up his body and make his tongue falter. 

He moved, stroking, putting near painful pressure upon him, every movement leaving Leo with  some  physical reaction. It seemed Leo had forgotten to try to be quiet, because he was churring, and was churring  loudly . But he couldn't find it in himself to care. 

Especially after Leonardo pulled off for air, speaking with a soft, "D- Donnie, please," before once again putting his mouth around him.  Ah . This was totally it. Donatello felt estatic. It was small, a short, little plea, but it made Donnie feel like he was aflame from the inside out. 

He needed to push this further. 

He pushed against Leo's forehead, pulling him off (no matter how much he adored the sensation), staring at the teary eyes of his brother beneath him as he stopped all movement. "Tell me." 

"Wha... whahuh?" 

Is he stupid? "Tell me what about me turned you on so much." 

Leo looked at him in utter surprise, but that quickly turned to desperation as Donnie's foot grinded his dick against the inside of his thigh again. "F–uck... Dee, al- alright." 

He watched the flurry of emotions across his brother's face, ranging from hesitancy to being  turned on , finally speaking. "When..." His breath hitched as Donnie's foot moved. "When, uhm, you... you compliment me. N... nngh, don't..." 

Donatello started his ministrations again, having stopped a minute before. "Keep going," he said softly, maybe a little too softly. Praise, that he expected. 

"I... I-I, euhm, I kind of like– a- ah– when you make me feel dumb. When- when, you, uh, put me down..." 

"Really? Elaborate." Donatello was so tense. Leo  liked  when he bullied him? That recontextualized a lot of things. And was attractive.  Very . 

"Mnn– right. Eh- when you mock-  fuck !- mock me... mock me and dumb down things for- for me.  God , Donnie,  please –"

Donnie licked his lips. 

Cute. 

Leonardo was crying. He doesn't think Leo's even realized it, but he was. It was likely due to being overwhelmed by the whole situation, not just pleasure, but it was just beautiful. 

He cups Leonardo’s face, his thumb pressing against his lips until Leonardo’s tongue goes to meet it. He delights at the sensual expression, tears in his twin’s eyes with flushed cheeks and nose, eyes just as puffy and reddened from crying - his lips wobbling and his body visibly shaking. His so-called “leader” brother, always  arguing  brother whimpering on his knees in front of him. 

It wasn't anything crazy. But Donatello loved it. 

He was so focused on Leonardo's looks that he couldn't help but jump when he found Leo  crying out  with a yell of  his name , panting for air, and face just  vulgar , Donnie looking down and noticing Leo  came . 

Holy fuck , Donatello thought. He just made his brother cum. His twin. Leonardo. On... on his leg. And all over his own self. 

And both of them... loved it? Hopefully. But he wasn't done - at least if Leo would allow it. 

"Leon." He said in a sickly-sweet voice, delighting in Leo's exhaustion. He could feel himself melt a little with how Leo's eyes had a certain amount of affection in them that went beyond lust, making his grasp just the tiniest bit gentler. "Leon, you think you can go another round for me?" 

He nodded. Belatedly, but he did, his stupid overconfident smile on his face. "I could... do this forever. I was amazing, right?" 

...Normally he'd just laugh, but he felt a bit nice. "Yes. I suppose I could call that amazing."

He ignored the way that Leonardo perked up like some overexcited puppy, and ignored the way he found that extremely endearing. 

He glanced at either of the kitchen doors.  Not here . 

Severely embarrassed (they just  did that  in the  kitchen ), he very quickly dragged Leonardo to his lab, praying that nobody woke up to how obnoxious his twin was being, but knowing his family, they were all (hopefully) dead asleep. 

The second they entered the lab, Leo was shoved onto his bed, once again looking up at Donnie with wide eyes. He'd almost believe them to be innocent if it wasn't for the... well, sex part. 

Normally he'd never consider this, but maybe you can consider it mercy. He found himself on top of Leo, fingers inside of himself. It felt... weird, and honestly, kind of repulsive (their hands were not built for this sort of thing, and Donnie hates touching himself sexually whatsoever), but the way Leo was looking at him like he was some sort of god or goddess mostly made up for it. Preparation complete, and now somewhere  soundproof , Donatello felt much more comfortable. 

Leonardo carefully placed his hands on Donnie's thighs, and abruptly this whole thing felt a lot more intimate. Which was... good. It was good. 

Until Leo decided to ruin it with a "Wow, your thighs are sexy."  

Donnie smacked his head. "What is  wrong  with you, 'Nardo." 

"No- no, I'm serious." It seems he had recovered from earlier, so now his stupidity was back in full swing. "I didn't mention it earlier, but your thighs never fail to turn me on. When we spar one time you wrapped them around my-" 

"I'll choke you to death with them right now if you don't  shut up ." 

Donnie meant it to be a threat, but Leonardo looked like he was truly considering it. Freak. Not as if he was much better. 

Leonardo's dick was thankfully hard again - which happened almost instantly once he saw Donnie fingering himself above him. That made things a bit easier. 

He hesitated though. 

They were definitely still brothers. Just because this was consensual from both sides didn't make it okay. Plus, they were twins. He's sure that's a fetish somewhere, but it's 100% fucked up. 

...But they were also talking mutated humanoid turtles. Incestuous relations would not be the worst thing about them. And... they were in too deep already. Thoroughly having psyched himself up, he found himself slowly lowering himself down onto Leonardo's dick. 

Once fully inside, he admits it was rather different from touching himself. Or his attempts to. 

He could hear Leo gasp, matching the noise by hissing between his teeth. The main aforementioned difference is that while uncomfortable (more so just having something  in him  was uncomfortable, not the act itself), it felt a lot better. 

It was nothing exceptional, but it was clear on Leonardo's face that it was almost  too much  for him, already huffing. 

It was also different when he finally moved. 

He found himself sharply inhaling, surprised by the sudden spark of pleasure up his spine when he moved up and back down. 

He looked to Leo, who was  wincing , biting his already raw lip and leaving it bloody. He leaned in, giving a soft kiss that had him licking away the blood, enjoying the taste of copper on his tongue. It reminded him of the bitemarks that lay across either side of Leonardo's neck.  Pretty , he thought. Suits the self-proclaimed "pretty boy" of the team, doesn't it? 

When he pulled away from the kiss, Leo weakly called his name when he started moving again. "Donnie- Dee, w-wait, wait." 

Donatello stopped, looking at him questioningly. 

"It's-- it's too much. Give me a second."

Donnie felt weirdly enough that their roles should be swapped right now, but Leonardo's lewd noises distracted him from that train of thought completely. "Really?" He said teasingly as he rose up and down, ignoring the pleasure that shot through his core. The hands that once gripped his thighs lovingly raked down them, leaving angry scratch marks behind them. Donatello grunted in pain, glaring at Leonardo. 

"S-sorry, sorry,  sorry , Donnie. It's just– uhm,  tighter  than I expected. It's- it's a lot." Despite his self-confident tone, he was very plainly fighting against the urge to bring Donatello down upon him again. Donatello felt that rush of control he felt before, one of his hands trailing teasingly down Leonardo's plastron, watching the way he arched into the touch. 

That was more alluring than he thought it'd be. 

And then he started moving - moving without mercy (which he claimed to have before), wishing to see Leonardo come undone. And to his joy, Leonardo was. 

"W-wait, w– wait, D-Dee–" He cut himself off with a long moan- no, a mewl, a long, drawn-out whine. When Leo's tightly shut eyes opened once more, Donatello was met with tears once more. Fuck.  Yes . 

At each thrust, Leonardo held tighter and tighter onto him as if he'd disappeared, his nails scraping across his thighs and hips, leaving an array of fingerprint plum-colored bruises in their wake. Donatello himself couldn't help but make noise, churrs against Leonardo's neck and the slit of his ear. 

They met in kiss after kiss, each tasting messier and sweeter than the last, filling both of their chests with a certain  warmth . Each was more revoltingly romantic than the last, kisses going down their necks and over the tops of their plastrons. 

Then Leo hit a certain  spot , and Donnie couldn't help but just  yelp . He hadn't expected that, and neither had Leo from the astonishment on his face. It was the loudest Donatello had been that night. 

Donatello mentally cursed as he saw Leonardo grow elated, holding those scratched hips even  tighter , trying to hit it  again  and  again . 

Regretfully, he did. 

Donnie couldn't help but cry out, letting out hushed moans which made Leonardo all the more eager. Arms wrapped around Leo's neck, holding him close as their positions flipped, Donnie on his softshell as Leo fucked him from between his thighs. 

Donnie, for some semblance of control, tightened his arms around Leo's neck until his twin was short for breath. 

He swore he felt Leonardo throb inside him before he hit that spot inside him again that made him see  stars . Donnie already stimulated from earlier, knew he was close - especially from the way his core was tightening, leaving him all the more desperate for each thrust that went inside him. 

All the more desperate to hear every adorable call of his name that left Leonardo's lips. 

"D– Donnie,  oh , fuck.  Donnie . I  love you , I  love  you–" 

Donatello bit into Leonardo's neck, close to Leo's jaw, and locked his own jaw until he tasted blood. He sucked until he was sure it'd be bruised and bloody, raw and violet as he pulled away as if to show of Leo was  his , entirely. 

When he bit down again on the other side of Leo's neck, he could feel himself unraveling - for a moment his vision went white as his entire body tensed - feeling as if sparks were dancing along his skin as cum spilled on both of them. Leonardo fucked him through the orgasm, slowing as he saw Donatello pull away from his neck. 

"Can– can I keep going–  please ?" He  begged . 

Donatello pushed him down once again, returning to their original position. "Ass." He said, pulling off of Leonardo ("W-Wait, Donnie–") - his cock  so  hard and angry, leaking precum and coated in slick. He grabbed Leo's tail, gripping it as he felt it, swollen, twitching beneath his fingers. Leonardo  sobbed , thrashing and trying to shove Donnie's hands away. 

Donatello stared him down, and at his gaze, Leo slowly pulled his hands away like intimidated prey, instead opting for them to grasp at the sheets beneath him. "D- Dee." He whispered. 

Smiling, Donnie started jerking him off, his other hand still holding his tail  violently , the pain and pleasure sending Leonardo just weeping, fully, openly sobbing with churrs between. "D- Donnie, mi amor, I'm– fuck– I'm going to...!" 

And Donatello's hands stopped. 

Leo's eyes shot open, mouth open in a moan falling silent. "D... Don?" 

He tried to roll his hips, but Donatello didn't allow even the slightest movement with the grasp on his tail, sending a burst of just  delicious  pain up Leo's body and making his back  arch . He looked to Donatello, trying to look as pathetic as he could, pride long forgotten with the idea of orgasming in front of him. "Donnie, pl-  please . Please." 

Nothing. 

"A... ah, I'm sorry. I'm sorry I pushed you over... is that... is that it?" 

Donnie's thumb grazed over the tip, leaving Leonardo groaning. "Ah! Ngh,  yes . I'm sorry,  I'm sorry , I won't do it again– not without your  permission , I swear. Please, Donnie." 

And finally,  thank fuck , Donatello  moved . His hands moved over him once again, squeezing his tail and over his cock and finally  moving , feeling like a drowned man who could finally just  breathe . 

When he came, Donatello was sure you could hear it even  with  the soundproof walls. 

"There you go, Leon. Not that hard." He said, giving him a peck on the lips. 

...Though now he needed to clean his bed. And probably the kitchen. And Leo had the gall to pass out. This little  fucker . 

Trying to wake Leo was like trying to raise the dead,  theoretically impossible , but Donatello loved to do the impossible. Leo woke, mumbling, childishly sticking out his arms and making stupid grabby hands. 

Donnie did feel a bit bad, so he did end up picking him up, and carrying him to the bathtub kept in his lab. Even if his legs felt like jello. 

The bath was romantic – the two facing each other with their legs intertwined as Donatello scrubbed his body. Leonardo was now fully awake, he just wanted to be babied, and Donnie had given up fighting it. And the way Leonardo looked  giddy  at how delicately he was treating him, well, it was nice. 

"So, you love me  too , right? In not a brother way?" He asked for the nth time. 

Donatello groaned, getting more flustered and exasperated each time he was forced to say it. He gave Leo a little kick as he exclaimed his nth "Yes, I love you 'like that', Leon." 

Leonardo laughed, tipping his head back in a way that made Donatello smile. Though he did cringe a bit at all the bite marks. Leo was going to notice them at some point, right...?

"How long? Why? And why are you so bossy in bed? I thought you'd be more the  bratty~  type." 

"That's you, Leon."

Leo pouted. "C'mon, answer, answer." 

When Donatello answered with a loving smile and a quiet, " A while ," Leo decided maybe he didn't need to know - at least for now. Knowing Donnie loved him was enough.

"Though that doesn't answer my main question. What was with that at the end? Are you a sadi... oh, of course, you are. You're Donatello! Why didn't I think of that?" 

"Don't think I didn't notice you liked the choking."

Leo started sputtering, red-faced. 

  When they woke, it was dreamy, the two cuddling in the same bed - Leonardo spooning Donatello, warm and  together . 

It made Leo absolutely  grin , feeling so happy he could barely contain himself. Even if the way they got together was kind of... uncouth, and they probably needed to talk about stuff, it was still a solid 11/10 experience. Would recommend. Would do again. Hopefully daily!

To be honest, he may not be able to last if Donatello pulls stuff like that daily. 

He slowly slipped away from Donnie, stretching as he walked to Donatello's bathroom to at least wash his face before he went back to his room to change, get ready, etc. 

When he stared in the mirror he almost screamed. His neck .  DONATELLO.

What in the ZOMBIE APOCALYPSE .
