…god I don’t even know.  It wouldn’t go away until I wrote it.  I 1,010% blame lesnee for getting me back into TMNT at a time in my life when I have access to a thriving fandom platform.  It’s all her fault.  

Fandom: Teenage Mutant Ninja Turtles 2012

Rating: Explicit

Pairing: Leonardo/Raphael

Warnings: Turtle-like genitalia on sentient anthropomorphic mutant turtles, turtlecest, first time, NSFW (if the explicit rating wasn’t clue enough)

Author’s Note: I keep seeing art and fiction that gives the turtles very human-like genitalia, and turtles actually have really fuckin’ weird junk.  So I was thinking about them as they try to figure that out while being seeped in human culture, and this just… yeah.  I have no excuses.  

———————

Leonardo bit down on his lower lip, eyes clenched shut and breathing hard as he stroked himself.  Close, close, so close–

His door slammed open and he gave a startled shout before grabbing his blankets and yanking them up, then zeroed in on the intruder.

“Raph!” he protested, glaring at his brother.

Raphael was staring at him, then his hand slapped over his mouth, eyes going wide.  “Oh–oh, dude, I am so sorry,” he said, not sounding sorry at all.  He sounded like he was trying not to laugh. “Were you, uh…”

“Get out!” Leonardo said, sitting up, trying to keep his knees raised in a way that wouldn’t let the blanket show anything too clearly.  “Haven’t you ever heard of knocking?”

Raphael closed the door.  “Haven’t you ever heard of a lock?”

“You know Master Splinter–”

“It’s called a chair, dude.  You just sorta get the back under the knob…”  Raphael trailed off.  “Donnie and Mikey are drivin’ me nuts.  You gotta let me hang in here.”

Leonardo’s mouth dropped open as his brother flopped onto his bed.  “You can’t be serious, I’m, I’m kind of–I was– Go away!”

“C’mon, no one cares,” Raphael said, leaning back against the wall and shooting a grin over.  He met Leonardo’s glare, then the grin faded and his gaze dropped a bit.  “Uh–weird question.  Are you still, uh…like, out?”

Leonardo felt his face go three shades darker and he shifted uncomfortably.  “What do you think,” he muttered.  

“Right, cool,” Raphael said, and there was something strange to his voice.  “Hey, can I…see?”

“What!” Leonardo yelped.  “Why?”

“Well it’s just…”  Raphael fidgeted with his wrist ties.  “See, the thing is…minelooksreallyweirdandIdon’twanttoaskDonnieaboutitandIdon’tknowifit’snormalornotokay?”

“Uh…”  Leonardo blinked.  “Come again?”

“It looks weird!” Raphael snapped at him.  “Okay?  My–my thing looks crazy and I don’t know if it’s because of the turtle thing or the mutant thing, and it freaks me out!”

“Oh.”  Leonardo thought about that for a moment.  “So you want to see if I…”

“Look the same,” Raphael said.  “Yeah.”

“I…guess that wouldn’t be too bad,” Leonardo said, and felt his cock twitch a little at the thought.  His face flushed.  “Uh…”

“I won’t tell anyone, I swear,” Raphael said.  “I won’t even bring it up.  Ever.”

Leonardo sighed, then bit his lip and glanced away.  “Okay, why not.  I mean, it’s not like it would be that weird, right?  It’s just…a totally normal part of us.  And I’ve pretty much seen your guts before so…”

“So this would be no different, yeah,” Raphael said, clearly relieved.  “Think of all the gross stuff we’ve been through and survived, this is like, nothing.”

“Right, yeah,” Leonardo said, nodding.  “Uh, so, I guess…”  His heart was racing and blood was pumping through his body, making him rock hard again.  That was distracting.  “I guess I’ll just…”  His face was burning up, and Raphael didn’t really look any less uncomfortable, but his brother was clearly worried about the matter.  Leonardo took a deep breath, let it out, and tugged the blanket to the side.  

“Whoa,” Raphael said.

Leonardo buried his face in his hands.  “Dude, don’t say whoa, please.”

“Uh–sorry,” Raphael said, and then he was quiet as he looked.

Leonardo’s erection came almost halfway up the front of his shell, long and thin and dark, until the very head, which flared out like an inverted mushroom cap that would throb in and out when he was close to coming.  Inside the cap was a small, incredibly sensitive spike-like structure that his cum came from.  He’d been startled to see it the first few times, looking nothing like what he’d seen on the internet and in magazines.  Of course, those were human males, so he’d figured it was okay to be different, and tried not to think about how bizarre it was.

Raphael wasn’t saying anything.

Leonardo looked up through his fingers, feeling incredibly exposed.  “So…is that good, or what?” he asked.  “Does it look the same?”  Because damn it, now he was curious.

“Yeah,” Raphael said, voice cracking.  He cleared his throat quickly.  “Yeah, it’s, about like that.  Does yours, uh, when you, you know, is there more than one…”

“Oh god,” Leonardo muttered, and hid his face again.  “Yeah.”

“Oh good,” Raphael said, sounding relieved.  “So I’m not a freak.”

“That’s up for debate,” Leonardo muttered under his breath.  “But no, in this one thing, you’re just as much of a freak as the rest of us.”  He lowered his legs a little, and reached out for the blanket, pulling it up over one thigh.  He’d have to wrap it around his middle to hide his entire cock, and that just felt so…obvious.  “So, show me yours,” he said out of nowhere.

Raphael blanched.  “What?”

“I showed you mine, you show me yours,” Leonardo said, staring down at the mattress.  “That’s fair, right?”

“I–I guess, but…”

Why was he even asking this? Leonardo wondered.  “Either that or go back out with Mikey and Donnie,” he said.

Raphael glared at him.  “You want to make sure you’re not the freak?”

“Ugh.”  Leonardo hid his face again.  “No.  I don’t know.  You don’t have to, I just thought…”

What had he thought?

He was about to tell Raphael to just get out or he’d make him get out, when he glanced up to see his brother chewing on his lip.  Was Raph actually considering this?  Leonardo stared at him.  “Uh…“

“Just–don’t tell the guys I did this, okay?” Raphael said, and reached down between his legs.  

Now Leonardo couldn’t look away.  He wasn’t even touching himself–because that would be weird–and he felt like he was about to come.  What the heck?

Raphael’s fingers were moving together, stroking over that spot right below his shell.  His breath was a little shaky, but so was Leonardo’s, especially when the erection started to curl upwards.  Raphael kept stroking the base, his eyes shut as he worked at it, and Leonardo found himself wondering what he was imagining.  

“Uh…there,” Raphael finally said, a little while later, and opened his eyes again to look at Leonardo.  He was blushing darkly as Leonardo looked his cock up and down.  

It was shorter than his, but not by much, and noticeably thicker and redder.  The bulbous head was fat, and pulsing a little.  

“Um,” Leonardo said, and leaned forward a little bit.  He brought his hand lightly to rest on his own erection.  “Yeah.  I think–uh–I think it’s the turtle thing, then.  If it was the mutant thing they might all be, uh, different?”

“Right, yeah, that makes sense,” Raphael said quickly, and he leaned sideways.  “Just, sort of made bigger like everything else.”

“Bigger is right,” Leonardo said with a smirk, getting a startled look from his brother, before Raphael joined him in laughing.  It seemed to break the tension a little and Raphael shifted closer.  

“So uh, what now?” he asked.

“Um…” Leonardo bit his lower lip.  “I guess we kinda should…I mean, if you want to leave, you gotta…”

“Not walk around like this, right,” Raphael said, looking down at himself.  “Takes forever to go away on its own sometimes.”

“Maybe you should just…help it along?” Leonardo asked, voice sounding squeaky even to his own ears.

“I…guess it couldn’t hurt,” Raphael said with a shrug that looked like more bravado than anything, and slowly moved his hand up and down.  

Leonardo leaned forward.  He couldn’t look away.  His cock was throbbing.  “Do you mind if–”

“Not at all,” Raphael said quickly, and then cleared his throat.  “I mean, no, dude, do your thing.  We’re both cool with it, not a big deal.”

“Right.  Not a big deal,” Leonardo said, and started stroking himself.  Slow, steady sweeps with his hand.  He didn’t want this to be over too quickly for some reason.  “Raph,” he whispered suddenly.

Raphael opened his eyes and looked over, and then down.  He swallowed, and his next breath was shaky.  “L-Leo.”  He scooched closer.  “Do you feel really…”

“Hot?” Leonardo managed.

Raphael nodded, meeting his eyes.  

“Yeah.”

“God.”

“Yeah.”

Leonardo’s gaze shifted lower, onto Raphael’s cock, his brother’s hand.  Raphael followed it, saw what he was staring at, and moaned quietly.  Slowly, surely, their strokes came even with each other, the slow up and down along the shafts, the slight twist of their wrists.

“C’mere,” Leonardo whispered in a daze, and held his other arm out.  Raphael moved closer, so they were sitting next to each other, leaning back against the headboard.  Their thighs pressed together.  “This is–”  He swallowed.  "Probably really wrong or something.”

“Shut up.  Don’t care.”  Raphael made an almost pained sound, pressed closer, and then–

The tips brushed together and the two froze, both of them staring down, and then at each other.  Then Leonardo bumped his hips up a little, pressing a bit harder, and Raphael’s eyes got huge.  

“Sorry,” Leonardo whispered, not sure why he was apologizing, or what for.

“Fuck, dude,” Raphael said, and the curse was sharp and startling, something they weren’t allowed to say, but then again… “Don’t stop.”

Leonardo gasped for his next breath as they rolled closer to each other, bringing the bulbous heads flush, rubbing them together.  “Raph–”  

Raphael hooked one of his legs over Leonardo’s and the shafts pressed fully against each other when he pushed his hips forward.  Leonardo gave a sharp, startled cry and thrust back, and then they started stroking themselves.  

Their hands hit each other, tangled together, and then Leonardo wrapped his fingers around both their erections and gave a firm squeeze.  Raphael swore again and copied him, and very quickly, their hands were moving in time together, up and down.  

“Oh god,” Raphael moaned.  “Oh god, oh god–”

Leonardo tried to shush him as he got louder and louder.  There was no way Donatello and Michelangelo wouldn’t hear him soon.  His left arm was trapped underneath Raphael, his right hand was–was–

He looked down.  The pulsing heads were moving together, and he whimpered as the sensitive inner spikes touched.  His right hand was occupied.  

Raphael moaned again, and Leonardo did the only thing he could think of to quiet him.  He leaned in and pressed their mouths together.  

Raphael froze in shock for a moment, giving a muffled protest, and then he was grabbing the back of Leonardo’s head and pulling him into a second, harder kiss.  Their tongues tangled together and their breathless moans were traded back and forth.  Hearts pounding, the kiss barely ever broke as they stroked and pushed, rocking together.  Leonardo thought that Master Splinter could have been standing right next to them shouting commands and they wouldn’t even notice.

“Leo I’m gonna–” Raphael gasped, and then with a hard throb from his cock and a short, jerky stroke, he came, shooting all over Leonardo’s shell, their hands, his brother’s erection.  

It was too much for Leonardo and he came a second later, shuddering and freezing as every muscle in his body seized up.  Hot cum pumped out of his cock, mixing with Raphael’s, and their kiss stayed locked tight the entire time.  

When they finally slumped down, they were breathing as hard as they did after the hardest workout, and without thinking, Leonardo lifted his cum-covered hand and pressed it to Raphael’s face as he pushed for another kiss.  

Raphael gave it to him, and then shivered as their heads continued to nudge together.  “‘S sensitive now,” he whispered.  

“Yeah,” Leonardo said, and drew back a little.  

They stared at each other.

“So…” Raphael said.

“I dunno, dude,” Leonardo answered.  “That was…”

“Felt good.”

“Yeah.”  A pause.  “Kinda right.  Can I…keep kissing you?”

Raphael nodded eagerly as they hooked together with arms and legs and pressed close.
