Work Text:
There was a code a true swordsman needed to live by. It demanded he be honorable. That he be wise. That he live and die by the sword. And that he swear fealty to his lord and master.
For the entirety of his young life, Leonardo had those tenets drilled into his head the moment he could understand words. He had been raised under the hand of a master, one who molded fresh prospects into hardened blades. Future guards, potential soldiers, possible tutors in the way of the sword. Leo believed the latter to be his lot in life, to replace his sensei once he passed, but it seemed fate had different plans.
The emperor had a son, a baby boy to take on his crown, and such a precious treasure demanded an even better guard. Someone who'd gladly give up everything they could for the child, a swordsman of the highest caliber. It was a title that coincided with royalty, politicians, philosophers, and more. A position guaranteed to mark Leonardo down in the annals of his country. So he trained, and trained, and trained, until a few years had hardened him into a master in all but name.
The prince's fifth birthday was the day his personal guard would be selected, one out of multiple candidates from across the land. The choice was to be determined by a tournament, and the victor would take the title. It was meant to be bloody, to be violent, to end more than a few lives right then and there on the playing field.
Leonardo remained on the sidelines, watching the other contestants, steeling himself up for what was to come. Hidden behind the grandstands, he didn't expect to feel a tiny hand tug on the end of his tunic. Looking down, there was a round-faced turtle, freckled across his rosy cheeks, his eyes as big and bright as the sky. Leonardo looked around for his mother, but when he saw he was alone, he turned his attention to the child.
"Hey there, you lost?" He asked, and he was answered by the boy silently begging to be picked up. Better than letting him run around this place. Leo scooped him up into his arms, and the moment he did, the boy cupped his face and giggled.
"Pretty!"
"I beg your pardon?"
The boy tapped him on the nose and said with impish glee, "You're pretty!"
Leo just laughed it off, walking towards the vendors to find his parents. He didn't expect the crowd to gasp and gawk at him, all parting as he traveled through. His confusion melted away when some stranger reached for the child, making the little one scream, and Leo jumped into action.
Within seconds, his sword was pulled out of its hilt, gleaming in the light. The would-be assailant put their hands up and backed away, along with the rest of the crowd.
A lizard approached him, looking frazzled as she gripped the edges of her skirt in her hands. "Young man, please release the prince at once!"
The prince?
The little boy stuck his tongue out at her, and wrapped his arms tight around Leo's neck. It was obvious he wasn't going to budge.
When she was followed by a group of the emperor's guard, all standing tall in their silver armor with swords to match, Leo had enough sense to put his weapon away and try to pry the child off.
Easier said than done, given he refused and held on tighter, squealing out, "No! I wanna stay with you!"
Immovable little thing that he was, he was glued to Leonardo, and the young man had no choice but to let himself be dragged over to the emperor's personal box.
He expected to stand there once he won the tournament, not as the prince's new toy, but it seemed the emperor was mostly humored by the whole affair. The grand, old terrapin sat in his plush chair, and gestured down to the duo below.
"Found my son, have you? I am quite grateful, the little monster has the tendency to run off." He said, earning a glare from the boy. "Tell me, young man, what is your name?"
Leo stepped forward, proudly replying, "Leonardo, of house Hamato."
"One of Hamato's boys, eh?" He seemed to consider the creature before him, turning to whisper in the empress' ear, before addressing his son, "And you, Michelangelo? Do you like this man?"
The child nodded frantically, practically nuzzling his face into Leo's neck.
The emperor laughed, "It is decided then. You shall be Sir Leonardo, my son's personal guard."
Everything seemed to move in a blur after that.
Leo was whisked away to the castle, where a grand ceremony was conducted to the public. Under the emperor's own hand, he appointed Leo as the sole guardian of the heir, and made him swear an oath to die for the boy, if need be. And of course, Leo made his vows, while the prince gave him a goofy smile.
When all was said and done, Leo was given a room adjacent to the boy's, separated only by a door. While his room was nice enough, Michelangelo's was grand. It had a massive fireplace, and bookshelves stuffed to the brim, and a bed far too large for his size, hugged by an intricate canopy.
Leo was about to bid the prince goodnight, so he could retire to his chambers, but the boy stopped him before he could.
He beckoned Leo over to the bed, and once he was close enough, he said, "Sleep in here with me."
Leo tried to retain his professionalism as he replied, "I don't think that would be appropriate of me, your Highness."
"Ugh, none of that. Just call me Mikey."
"A-alright… Mikey."
Mikey smiled at him and patted the bed expectantly. "Hurry up, Leo! I'm tired."
Leo hesitated, but held his feet firm. Even if he was a prince, he was a child, and as a teenager on the cusp of manhood, Leo needed his space.
"Look, your- I mean, Mikey." Leo looked around, trying to find an escape route. He perked up once he heard the rattle of armor walking by, another guard making his rounds. He turned to Mikey, putting on a serious front as he said, "It's very important that I do my rounds first. I'm your personal guard, so I need to make sure you're safe. Once I'm done, then I'll come lay down with you."
Mikey seemed to consider that, pursing his lips in thought. Leo could almost see the gears working in that little head of his.
"Fine, but I'll be waiting."
Leo bowed to him deeply, and scurried outside the room. He couldn't go too far- he needed to be with the prince at all times, after all- so he leaned on the wall across the hall and waited.
He wasn't sure how much time had passed before he pressed his ear against the door, hearing soft snoring that indicated it was safe to sneak in. For such a rambunctious, little creature, Mikey sure looked cherubic, snuggled up beneath his blankets. Leo wouldn't think as much once morning approached.
During the daylight hours, Leo had his hands full trying to keep Mikey out of trouble. Whether it was sneaking into the kitchen, or running into the library, Leo had to catch and corral the youngster, only for him to run off once more.
He would only sit still if Leo was holding him, so the young guard had no choice but to act more like a royal seat cushion, sitting down with Mikey in his lap. It was embarrassing enough, only made worse having to do it through all of the boy's appointments.
Hopefully age would temper him, but it seemed Mikey settled into this habit, even as the years passed and he grew larger. Perhaps a dose of reality would shake some sense into him.
During a moment of solitude, while the prince and his guard strolled through the garden, Leo spoke up, "May I speak with you, Mikey?"
The boy balanced across a stone bench and giggled, "You're always so formal. Just tell me what's on your mind!"
Leo thought for a moment, watching him play in the fading sunlight, and continued, "I, um, I don't think I should have you in my lap all the time."
That put the fun to a screeching halt. He genuinely hated the hurt pout he received in return.
"How come?"
"It's not appropriate to do that in front of others, my lord."
Mikey huffed, pudgy arms crossed over his chest, cheeks swelling red with frustration.
"We don't do it that much!"
"Oh? We don't?" Leo lifted his hands to list on his fingers, "You'll sit on my lap during your music lessons, during your history lessons, during mathematics, during meetings that you find boring, during-"
"Okay! Okay! Fine!"
Mikey stomped off, only getting a few steps away. He stood with his back turned to Leo, tense and angry, like he was about to pop. A tantrum was the last thing Leo wanted, so he carefully approached and sat on his knees, close so he could whisper.
"Look, Mikey, I don't like doing that sort of stuff in front of others. Sometimes they'll stare at us, and I get embarrassed. You understand that, don't you?"
Mikey sniffled, rubbing his nose, and nodded. Leo thought that was the end of it, until the boy turned to him and said, "Can we do it while we're alone?"
Oh, how could he deny such a request? Especially when the one giving it had such big eyes and pouty lips. It honestly broke his resolve.
He sighed, "Fine. But only when we're alone."
Mikey smiled at him, that ruddy color staining his cheeks and highlighting those spreading freckles. He looked one way, then another, checking over each shoulder, and finally whispered, "I think we're alone right now!"
As a man of honor, he was bound to fulfill the request. Leo stood up, scooping the boy into his arms, so they could both sit on the bench and watch the stars poke out of the heavens.
A few more years came and went, Mikey getting taller and wider, always gluing himself to Leo's lap in private. In public, he had gotten in the habit of standing close to his guard, sometimes holding his hand during events he found to be too much for his hyper mind.
During a celebration, where the royal family sat on their thrones, Leo stood by his lord and watched the crowd spin and dance. Mikey looked antsy, like he couldn't keep still in his seat. He finally turned to the empress and squeaked out, "Mama? Can Leo take me out there? I wanna dance!"
She looked at the two of them, and after a soft smile, she said, "Yes, yes, as long as it's okay with Leonardo."
The pressure now fell on Leo's shoulders, two royals looking at him expectantly. He couldn't say no, even if he tried.
Leo moved to bow to the boy, and said with practiced civility, "I'd be honored to escort you to the dance floor, your Highness."
Mikey giggled, much too happy to grab onto the offered hand, leading the way down into the crowd below. He was tall enough to reach up to Leo's midsection, easily wrapping his arms around the man's frame, looking up at him with pure adoration. Leo honestly couldn't look anywhere else.
His attention only shifted when a small crowd of women circled around them, all cooing about the cuteness of the scene.
"What a fine gentleman! Playing with the prince like that." Said one.
Another produced a coquettish grin as she added, "And so handsome too! I bet he'd make a fine father some day."
They all went on like that, making comment after comment that made Leo blush. He turned back to his little partner when Mikey tugged on his tunic and pouted in his direction.
"Pick me up." He demanded, waiting for Leo to do so, and when he did, he wrapped his arms tight around his neck.
In this new position, Leo had no choice but to hold onto Mikey's thighs to keep him aloft, the soft skin giving underneath his thick fingertips. It honestly made him nervous, and he didn't know why.
The women continued to gossip and giggle, but Leo paid them no mind. He was busy listening to the boy whisper in his ear, "They can't have you, you're mine."
Something changed after that.
Perhaps Mikey's behavior towards him was more than childish affection. He showed no love towards his governess, or towards his tutors. No, his love went to Leo and to Leo alone.
He'd always drift his attention towards Leo, meeting him with a bashful smile if he got caught. Or he'd insist on sharing sweets with him, ensuring Leo ate his half before digging into his own. Sometimes he'd trace patterns into Leo's arms when they sat together, and it took Leo a while to realize he was drawing hearts.
One night in particular, when they settled into the prince's chambers, Mikey insisted Leo sit with him on the bed. When he did, expecting the prince to sit in his lap like he usually did, he was surprised when the boy took a different position.
He straddled Leo's thighs, standing on his knees so they could be face to face. His smile spoke of innocence, but his eyes read of curiosity.
"Leo, can we try something?" He said, nervously twiddling his fingers against Leo's shoulders.
The man watched him cautiously, but nodded.
"Okay! Umm, close your eyes first."
"Why do I need to-"
"Just do it! And no peeking!"
Leo complied, eyes shut tight. He could hear Mikey breathe heavily, a small gulp in his throat, before he felt heat draw close to his face. Was Mikey getting closer? He got his answer when he felt the gentle press of lips against his own.
He couldn't exactly yank away or push him off, the risk of hurting his charge was too high. Leo merely brought his hands up, ready to grab onto Mikey, but he froze when he opened his eyes.
Mikey looked so peaceful, blushing such a pretty color. The soft little sigh against his mouth destroyed all resolve, so Leo gave up and allowed Mikey to continue. Curiosity and exploration were healthy things for a boy to have, weren't they? At least Mikey didn't push this already delicate boundary, remaining pressed close, only pulling away once he had his fill.
He looked at Leo with half-lidded eyes, hazy and glazed, a satisfied sigh spilling out of his lips as he whispered, "Wow…"
Leo felt his face grow hot, some chemical reaction pumping his blood in an odd direction. He needed to leave or this situation would get more inappropriate than it already was.
He tried to stand, but Mikey used his full weight to press him against the bed, giggling to himself.
"Did you like it?" He asked.
What was he supposed to say? This was wrong in every sense! He couldn't say yes without the omnipotent spirits overhearing what a sinful beast he had become. Leo licked his lips and stuttered out, "It was… it was very nice, Mikey."
Thankfully, that answer seemed suitable enough, and Mikey rolled onto the bed, giddy as he snuggled into the blankets. Leo wasted no time getting up to rush to his room, bidding his lord a quick goodnight.
Mikey made the time that followed much worse, begging for kisses when they were alone, and who was Leo to deny him? When Leo needed to escort him from lesson to lesson, Mikey insisted on sharing a quick peck during the transition, while they had a moment to spare. And when they strolled through the gardens, Mikey would pick a secluded spot underneath a peach tree, just so he and Leo could press their lips together without worry. The worst came when Mikey asked for a kiss right after a bath, wet and warm and begging to be held. It drove Leo insane.
Perhaps fate had it out for him, because Mikey only continued to push his boundaries.
It was the evening of Mikey's birthday, and after all the celebration and presents, the boy settled down into his bed. All the excitement had worn him out, enough to not ask for a goodnight kiss. Which Leo was grateful for, since he could sneak into his room and tend to more… private matters.
He'd been alone for too long, the only touches available to him from his prince or his own hand. The latter seemed the more sensible option. Besides, he couldn't let Mikey see him in such a lewd light. Kisses were one thing, but this was another.
Leo dropped his clothes to the floor, leaning back on the bed so he could finger his slit. It had been so long, it only took a few touches to make himself wet. He didn't want to make a bigger mess than he already was, so once he deemed himself aroused enough, he dropped down into his palm.
It felt so good feeling the weight of himself in his hand, thick and heavy and rich with pumping blood. Leo licked his upper lip and pumped himself rapidly, the pressure just enough to make him groan. His breath grew heavy, the muscles in his stomach coiling tightly with each slap of skin on skin.
He was too invested with his actions to notice the door he shared with Mikey creak open, nor the pattering of feet across the floor. Only when he felt something press onto his bed did he look up.
Leo quickly covered himself, swallowing down a yelp as he saw Mikey loom between his legs. The boy switched his eyes between Leo's barely hidden arousal and his embarrassed face, finally asking, "What are you doing?"
"Whu-you… why are you up? You're supposed to be in bed!"
"That doesn't answer my question." He moved onto the bed, dangerously close to that warm spot Leo tried to hide. "What are you doing?"
Leo struggled for an answer, so busy looking for an explanation that he failed to notice Mikey reaching out to uncover him. When cold air brushed against him, Leo brought his thighs together.
"Leo, as your prince, I demand that you let me see."
Of course he'd pull rank in a moment like this. He knew what he was doing too, looking so smug as Leo felt his face burn.
He was honor bound to follow command, so hesitantly, he spread his thighs and removed his hands. His erection had faltered, somewhat, but still stood proud underneath the scrutiny. Leo felt shame when he looked at Mikey's face, so filled with wonder and awe, and his cock twitched in response.
"Why does it look like that?" Mikey asked, and his innocence nearly broke Leo's already weakening constitution.
Embarrassed enough, Leo covered his face as he mumbled, "It looks like that because… I'm excited."
"Excited? But mine doesn't look like that when I get excited."
He couldn't exactly use adult words that were beyond the boy's comprehension, so he tried a different tactic. "This is a different kind of excited. One that feels good when I, uh…" Leo faltered, loosely gesturing to his length. "When I touch here."
Mikey, sweet, playful, angelic little Mikey, just had to ask, "Can I touch it?"
Leo had to bite back a groan at that.
"No."
"Ugh, why not?"
There were a hundred different reasons Leo could list off the top of his head, but they'd more than likely fall upon deaf ears. Mikey was not only a child, but a spoiled one at that, so denial to him was an offense against his very nature.
"Come on, Leo! Please? It's my birthday!"
The very idea made him shudder, but he needed to remain strong. Perhaps a compromise would solve the problem.
"I won't let you touch it," Mikey was about to pout again, so he quickly added, "But! I can… I can let you watch me do it. How about that?"
Leo dreaded whichever answer he'd receive, stomach doing a flip when Mikey agreed enthusiastically.
Might as well get this done and over with.
Taking himself in hand, he decided it was best to close his eyes, avoid looking at that youthful face gawking at him as he resumed his actions. Leo gulped, slowly stroking himself with an unsure hand, keeping any noise in his throat down to a minimum.
The pace he set lacked the fervor of before, the need of release now a need to be out of this situation. Oh, what would the Emperor think if he found out? Or any of the staff? Or just some big-mouthed stranger? Gossip traveled like the plague, so if this got out, it would certainly reach his Sensei-
"Are you okay Leo? You're making a funny face."
Leo peeked an eye open, and Mikey's sweet little face looked so concerned, quelling his fears, if only for a moment. It was just the two of them, no one else in the world to bother them, sharing something for only the walls to see.
There was no need to alarm the boy, so Leo put on a soft smile and said, "Just a little nervous, that's all."
Mikey perked up at that. "Oh! I can help!"
Before he could speak, the boy scrambled onto the bed, scooting next to Leo as he pulled on the man's shoulders. Once Leo leaned far enough within his reach, Mikey cupped his cheek and kissed him. Something so soft yet firm, it only made the bubbling in Leo's gut burst into flames.
His hand sped up, the sensation making him twitch and groan into the contact, Mikey responding with a little hum. Such a lovely sound, would he make more?
Leo tested the waters by flicking his tongue against Mikey's bottom lip, feeling the boy flinch, but remain in place. So he tried it again, providing a long lick, making the other whimper. After a third try, Mikey met him in the middle with a shy reach of his tongue, and Leo churred at the feeling.
What a terrible, dirty man he was, for wanting to push further and ravish Mikey's mouth with teeth and tongue, if only to hear another sound. But that was nothing more than his hormone-addled brain talking, demanding he satisfy himself with any bit of warmth.
If he wanted to retain any honor and respect he had left, he needed to ignore animalistic need and control himself.
Leo pulled away and sped his hand up, panting for breath, even as his charge leaned over his bicep to get a look. He should've felt shame, but all he felt was excitement under the scrutiny, his building guilt blinded by an impending release.
One last peek at Mikey sealed his fate, and he bit back a moan, spilling over his eager fist. Leo gave a few more pumps until he was satisfied, flushed and wet with his own fluids.
The afterglow was hard to enjoy when Mikey mumbled out, "Did you just pee?"
"...No."
"What is that stuff then?"
That was a discussion for another time, this impromptu demonstration had already gotten far out of hand.
With enough convincing, Leo got the boy back into bed, unable to sleep himself when confronted by the realization of what he had just done. If he was lucky, this whole situation could be forgotten, swept under the rug, their dirty, little secret never allowed to see the light again.
Then again, ever since he became a guard, was he ever lucky?
Perhaps he spurred on Mikey's natural curiosity, he was a boy on the cusp of puberty, so it was natural he'd try to explore. Not on his own, of course, never on his own. He had Leo to guide him, whether the man wanted to or not.
A week had barely passed since the incident when Mikey called Leo into his room one night, telling him it was urgent. Given the hour, Leo had to rub the sleep out of his eyes, his body going into full-alert when he saw his charge.
Mikey was on his knees on the bed, night gown pulled up to his chest, leaving his stomach and thighs bare. There, sticking out against the bottom of his shell, was a small erection, pink and wet. His face was flushed, breaths heavy, and Leo nearly keeled over from the rush of blood going south.
The boy whined, "Leo… I-I was trying to do the thing you were, but I don't think I'm doing it right…"
Leo gulped, mouth dry as he wet his upper lip. He couldn't remove his eyes from the view, such a soft, pliable body shivering with need. It was maddening.
Had he been a weaker man, he'd probably run over there and claim him in every conceivable way. Thankfully, he still liked to pretend he had some dignity in these situations, so he approached slowly, stopping at the edge of the bed, maintaining eye contact.
"You… are you okay, Mikey? Does it hurt?" He tried, fists clenching and unclenching against his thighs.
The boy shook his head, small noises in his throat as he shifted. "Feels good, but I want more…" He shot a doe-eyed glance at the man and fluttered his lashes, "Please help, Leo?"
How could he say no?
Leo carefully sat on the bed, patting his lap. Mikey nearly toppled him over in his scramble, nestling himself snugly against Leo's chest. He looked brighter now, a smile curled against his rosy cheeks, eagerly waiting for whatever his guard had to give. It made Leo's heart ache more than that feeling in his groin.
"Okay…" He breathed out, "I'm gonna touch you, okay? And if it hurts, you tell me."
The boy nodded, and Leo tipped the both of them back against the duvet, using this new position to pull one of Mikey's legs up. He was so small in comparison, Leo easily slipping a hand underneath his knee to hold him in place, other hand snaking out to massage at his inner thigh.
Leo was used to this sort of touching, but these newfound sensations must've been intense for his prince, given he twitched and mewled from the attention, and Leo hadn't fully explored him yet. He carefully squeezed his way up, gauging Mikey's reactions, watching his face pinch into something almost painful when Leo rubbed at his cock.
He didn't need to ask, though, Mikey whimpered out, "Oh! L-Leo…"
His hand was too big to properly encase him, instead caressing against his tender flesh, letting friction do the work. Mikey met each pet with a roll of his hips, staring off into space. Leo wondered just how much he could give to him without overwhelming.
Holding Mikey tight against him, he whispered, "Can I try something?"
Through teary eyes, he looked at the man and nodded.
Leo hated how excited he felt, but he was too far gone, there was no going back. Might as well give in. He brought his free hand up towards Mikey's mouth, pressing a fingertip against his lips.
"Suck on it." He said, voice gravelly, clearing his throat before he continued, "Get it nice and wet, and I'll keep going."
Mikey switched his gaze to the offered digit, his half-lidded eyes considering it before parting his mouth and latching onto it. Leo could feel a small, hot tongue lave against him, suckling him like a starving lamb. It made him shiver. Once he deemed it saturated enough, he slid it out with a lewd pop , followed by strings of saliva that dripped onto Mikey's chin.
That wet finger carefully mapped its way down his little body, grazing over the plates of his plastron, finally ending back between plush thighs. Leo teased it over Mikey's erection, watching his face as he slipped past it, carefully brushing against the folds of his slit.
" Mmph… Leo?"
Leo leaned in to press a kiss to his temple. "I think it'll feel really good inside you, if you wanna try."
Mikey must've been drunk on lust, puckering his lips as he nodded eagerly. The man peppered kisses across his cheeks to distract him, slowly prodding his finger against that small hole underneath his fingertip. The folds gave way when he eased his way in.
The reaction was predictable. A flinch, a gasp, body not welcoming the intrusion, but Leo kept him complaisant with sweet kisses against his lips. It only took a few shallow thrusts before Mikey melted into it, tension fading from his body. He moaned against Leo's mouth, cupping his cheeks with twitchy fingers.
When Leo curled his finger up, the reaction was addictive, Mikey going cross-eyed and babbling out wetly, "L- mmm- Leo! Right there! Right there, please! Again-"
He was cut off by a chirp as Leo complied, pushing harder, faster, thoroughly fucking the boy with his finger. It was a riveting sight, the sounds and sensations enough to corrupt even the most noble of men, Leo easily falling prey to the love of his prince.
Perhaps he got too vigorous in his ministrations, because the boy arched back suddenly, eyes wide as clear fluid gushed out of him, squirting across Leo's palm. Mikey tensed up, a squeaky churr caught in his throat, then finally settled down.
That woke Leo out of his haze. He pulled his finger out, followed by the warm trickle of slick, and cupped Mikey's cheeks as he said, "Mikey? Are you okay?"
The boy weakly turned in his direction, sluggish in every movement except his breathing, a slow blink the answer as he let everything sink in.
"Mikey! I need an answer, come on! Oh, gods above, what did I do-"
Mikey chuckled weakly, impish glee overtaking his face. His voice was nothing more than a raspy breath, "That was… amazing."
The scare shocked some sense into Leo, the relief taking the rest of his energy with it. He used a dampened cloth to wipe up the mess, settling a sleepy prince back against his pillows, ready to go back to sleep himself. Leo didn't get far when Mikey pulled onto his sleeve.
"Sleep with me." He said, and he looked so small and perfect, Leo couldn't refuse.
