alright so this is kinda smut, but not really.
i'd like to request for a reader who is dating the turtles (or just one if you're not trying to write a whole lot) and they've made out but haven't done much else due to the differences, but reader had a great idea to watch documentaries on how turtles are.
reader's literally just studying turtle anatomy, alone and peaceful to be a good partner, and they get caught.
you can decide how that goes further, whether there be an actual smut moment or not!
(sorry if it's rushed and doesn't make sense!)
Warning!! ⚠️- Seriously. Read this before you read the rest of this! This has a poly reader and turtles. It is said that reader is dating all of the turtles. Raph is the main interaction but it is said all of them! If you are uncomfortable with this please skip this! This isn't quite smut but it is suggestive! Please be aware of these things before reading!!!
Part 2!! - finished! Feel free to check out!
The lair was quiet for once.
Mikey was topside grabbing groceries with Donnie, Leo was meditating in his room—or pretending to, more likely—and you had the main area to yourself. The old couch creaked as you settled in, laptop balanced on your knees, a notebook open beside you filled with messy scribbles.
You'd been dating them for a few months now. All four of them, in your own arrangement that somehow worked. The kisses were electric, the cuddling perfect, the way they handled you like something precious made your chest ache. But things hadn't progressed past heavy makeouts and wandering hands, and you knew why.
The size difference was intimidating.
Not just height—though at 5'2", everything about them was massive. But the anatomical differences. Shells, plastrons, the way their bodies were built so differently from humans. You wanted to be a good partner. You wanted to know what felt good for them, what to avoid, how to navigate the ridges and plates and sensitive spots without fumbling like an idiot.
So you'd done what any determined person would do.
You watched nature documentaries.
Specifically, turtle anatomy documentaries. Tortoise mating rituals. Box turtle courtship behavior. A surprisingly detailed deep-dive into the sensory organs of aquatic turtles that had led you down a two-hour rabbit hole.
The current video was playing softly—a British narrator explaining the cloaca and its role in reproduction for certain species. You were taking notes furiously, tongue poking out in concentration.
"Okay, so… sensitive areas around the tail base… plastron tapping as a courtship signal… noted, noted…"
You didn't hear the heavy footsteps behind you.
You didn't notice the massive shadow falling over the couch.
The laptop went flying. You caught it—barely—clutching it to your chest like a shield as you twisted around to find Raph standing behind the couch, arms crossed, one brow ridge arched high. He was just there, silent as a predator, and the smirk on his face told you he knew exactly what he'd interrupted.
He snorted. "Bullshit. Heard the narrator talkin' 'bout cloacas."
Your face went nuclear red.
Raph leaned over the back of the couch, his massive arm reaching past you to grab the laptop from your shaking hands. You tried to hold on, but he was Raph, and you were a tiny human with noodle arms. He turned the screen toward himself, eyes scanning the video.
A nature documentary. A diagram of a turtle's internal anatomy. Your notebook full of detailed observations.
His expression shifted—surprise, then something softer, then a deep, rumbling chuckle that vibrated through the couch.
"You been watchin' turtle porn to get ready for us?"
"It's not porn! It's educational!"
"Educational," he repeated, deadpan. He scrolled through the video timeline, landing on a section about shell sensitivity. "Uh-huh. And what's this part about?"
You buried your face in your hands. "I just wanted to be a good partner, okay?! I don't know how to—how to touch you without hurting you, or what feels good, or if there's—I don't—"
Warm, calloused fingers pried your hands away from your face. Raph had moved around the couch, dropping onto the cushion beside you, his massive frame making the whole thing tilt. He set the laptop aside, then hooked a hand under your knees and lifted, pulling you onto his lap like you weighed nothing.
"Hey." His voice was rough but gentle, a tone he didn't use often. "Look at me."
You did, eyes wet with embarrassment.
Raph's scarred face softened. He cupped your cheek, thumb brushing away a stray tear.
"You're adorable, y'know that?"
"Same thing." He huffed a laugh. "Baby girl watched nature documentaries to figure out how to fuck her mutant turtle boyfriends. That's the sweetest, dumbest thing I've ever seen."
You groaned, trying to hide your face in his chest, but he held you firm.
Raph's expression was serious now, dark eyes holding yours.
"You wanna know how to touch me? You coulda just asked. I woulda showed you." His thumb traced your lower lip. "But this… this is cute. You went out of your way to learn for us. That means somethin'."
He reached down, grabbing the notebook from where it had fallen. He flipped through it, reading your cramped handwriting, the little diagrams you'd drawn.
"Plastron sensitivity," he read aloud. "Recommended approach: light pressure, circular motions." He looked at you, a slow grin spreading. "You even made notes."
"You got a whole section on tail handling. 'Caution: don't pull, support from base.'" He chuckled darkly. "Smart. Real smart."
He closed the notebook, setting it aside, then turned his full attention to you. His hands settled on your waist, squeezing gently.
"Tell you what. You did all this research for us. Seems only fair we return the favor."
His voice dropped, low and rough.
"Wanna put that knowledge to the test? I can teach you exactly what those documentaries left out."
He didn't push. Didn't pressure. He just waited, eyes locked on yours, giving you the choice.
When you finally nodded—small, shy, but sure—Raph's grin turned sharp and warm at the same time.
He lifted you easily, carrying you toward his corner of the lair, the notebook and laptop left forgotten on the couch.
"First lesson," he murmured against your hair. "My shell's sensitive along the edges. Light touches there make my whole body shiver."
He paused at the entrance to his space, looking down at you with something vulnerable beneath the bravado.
"Second lesson: you don't gotta study alone no more. We'll teach you together. All of us."
He pressed a kiss to your forehead.
Thank you for your request as always! I hope you enjoyed!! And thank everyone that had requests for being patient! My requests will be open again so feel free to request!
