Leo’s color was blue, striking cobalt and the urge to wear the color for him was strong as you looked through your closet. The past few weeks were a bit of a whirlwind, the brothers were constantly texting you ever since they had joined you and Finn for his vet appointment. Mikey was by far the most vocal of them, always wanting to call you or face time, many times unprompted giving you several heart attacks during class. You had to physically text him your schedule to avoid the jumpscare of the song Mr. Sandman every time he calls you. Letting out a soft huff you pulled out a navy-colored top and tossed it behind you, thoughts of your boys running through your head. Your cheeks flushed, jeez they weren’t even your boyfriends yet and you were already considering them yours.
You’re so mentally ill.
A puffy red jacket skimmed your fingers and it reminded you of Raph. He on the other hand didn’t text you as often you learned he liked to do most of his communication in person and has sneakily joined you for lunch in between your classes. Having access to many of the empty chemistry labs and writing classrooms had its perks. You were able to sneak him in to eat the lunch he’s brought for the two of you to enjoy together.
Donnie has been the same communication-wise, preferring texts to calls and still stopping by uninvited whenever he could, especially to walk you home from classes. He has been extra clingy lately, which you attributed to him feeling a little threatened by his brother's sudden interest in his girlfriend. Obviously, you reassured him in every way you could. Mostly with your lips pressed against his own as you pulled him inside your bedroom. You had to shake your head from the memories lest you get too caught up in your daydreaming and you’d have to cancel plans with Leo and call up Donnie instead.
You groaned banging your head against your closet door, Leo keep thinking of Leo. He was the most unpredictable of the brothers switching between, texting, calling, face time, and popping into your life to visit you. You smiled softly to yourself pulling out a pair of warm brown boots that stopped at your ankles with fuzz around the ankles. You pulled out a pair of black jeans and managed to find a cobalt blue shirt, the sleeves were long and hung loosely around your wrists. The shirt was littered with white little stars and you hoped something in the outfit and makeup would highlight the color of your eyes. You pulled away and did a little twirl in your mirror, flapping the sleeves of your blouse like a bird.
“Wow princesa…look at you.” You shrieked grabbing the nearest book and promptly chucking it at the intruder, Leo made out a strangled sound catching the book just inches from his face. “You’re lucky I like a woman who could kill me, sheesh-”
“Leo! What did I say about knocking? Give a girl some warning! I just finished changing-”
“Ah came too late then I’ll keep that in mind for next time.” He teased a mischievous glint in his eyes, he laughed at the glare you sent his way. Leo slipped into your room and sat lazily on your bed, “Well continue getting ready.” He mused grabbing one of your many stuffed animals and placing it in his lap.
“I still have to do my makeup considering you’re early. You’re gonna be bored just a warning.”
“How can I be bored when I have such a fine piece of art in front of me.”
You flushed all the way up to the tips of your ears, “that was terrible. You’re terrible.”
“You love me for it, don’t lie,” He mused watching you fiddle through your makeup bag he only recognized a few products. Mostly from seeing April apply them, on occasion he’d sniffed some out at a mall to try a few of the products. You waved him off as you applied the makeup with a steady hand, he tilted his head to the side watching you intently a goofy smile on his face. You could see him in your mirror as his feet continued to kick on the bed, it was the first time you noticed that he was dressed differently from his normal ninja attire. He had a light blue shirt on with a black vest and a nice pair of dress pants you couldn’t help but wonder where exactly he was taking you considering he was dressed so fancy.
“Alright Leon,” You mused turning to face him with a smile, “Where are we headed.” You slung your bag over your shoulder as he jumped up on his feet excitedly. He began humming softly slinging an arm around your waist effectively spinning you around, you giggled as he looked down at you.
“I suppose I should wait for the proper romantic moment to kiss you?”
“That’s how it works yes.” You hummed gently scratching under his chin, he seemed to let out a high-pitched churr nuzzling his chin into your hand, “So you better hope this date is romantic.”
“It’ll be so romantic you might even give me two kisses.”
“Don’t be cocky now. I’m a stubborn creature. Out of spite I just may not give you any kisses.”
“Trust me when I say that’s virtually impossible. My charm and quick wit are irresistible,” Leo mused putting you down on the ground and pulling out his katana. You raised a brow as the mystic portal opened blue lightning cracking around the edges displaying what looked to be another city. It sent a chill up your body the cold air brushing against your arms, “Before you say anything yes, this is the Hidden City. No, I did not clear it with Donatello, he’s paranoid. I know the place like the back of my hand,” Leo held up his hand to show you his palm, “Scout's honor.” He smiled goofily before holding out his hand to you, “Do you trust me?”
“Obviously.” You slid your hand into his own squeezing it tightly, “I trust you with my life.”
Leo seemed to pause his entire face lighting up in a deep red color, he let out a strangled sound seemingly trying to recover from his embarrassment. It was adorable and very Leo, you’ve learned over the past few weeks Leo could dish it out but he absolutely could not take it. “Obviously you would, obviously!” Leo chittered puffing out his chest, “Ready?” You nodded as he pulled you into the portal as soon as you were both through it snapped closed behind you. You found yourself standing outside what seemed to be a standard pizza restaurant, the name of it even was Run Of The Mill Pizza. “This is my favorite place. You’re gonna love it, whatever the owner says to you about me don’t believe it. He likes to make a habit of embarrassing me.”
“That’s quite the warning,” You mused, “I don’t know I may have to hear him out.”
“Please don’t.” Leo groaned, holding the door open for you like the gentleman he was before following inside and taking his arm in his own. You froze a little and Leo patted your arm at the host stand stood a living skeleton scolding another creature. “Hueso! Buddy!” Leo mused waving his arm high in the air, the skeleton monster froze before his socket seemed to twitch at the sound of Leo’s voice. He looked at Leo a frown present on his face, you wanted to question why a skeleton had a mustache but you kept your mouth closed shut. Reminding yourself about the mutant criminals running around topside were anything but normal looking, he wasn't even looking at you more pointedly looking at Leo. The two began talking in Spanish, Hueso grumbling in Leo’s direction arms crossed pointedly occasionally glancing at you. Leo laughed shyly seemingly trying to explain himself, it made you feel like you needed to learn Spanish so you could communicate with Leo better. You were snapped out of your daydreaming as Hueso snatched up two menus effectively hitting Leo on the head with one, before speaking directly to you.
“Hola welcome in, Leon’s told me it’s your first time in the Hidden City sí?”
“Yes. He insisted we come here to eat,” You smiled softly in his direction he flushed a soft pink refusing to look at Hueso who blinked a few times before a smirk spread across his face.
“Then we’ll make sure you get the best experience. My name is Senior Hueso, but you can call me Hueso hermosa dama.” He took your hand and pressed a gentle kiss to it, if you thought about how he was able to kiss your hand you’d give yourself a headache. Leo grunted watching you fumble to introduce yourself because you were flustered by his forwardness.
“Alright enough, enough. Don’t you think your wife will be mad to see you flirting?”
“Ah do I sense some jealousy Tortuga?” He mused teasing Leonardo much like a parental figure would their son, “Don’t worry your little human is all yours not to worry.” He tittered purposefully interlocking your elbows together before turning and walking you towards the table. Hueso put a menu in front of both of your faces as soon as you sit down, although he kept his voice the same volume so Leonardo would absolutely hear. “If he causes you any trouble please come and grab me I’ll kick him out.” He reassured, “Or if he’s holding you hostage please blink twice.”
“Alright, Hueso! You can leave now!” Leo snapped shooing his friend away rather forcefully which only caused Senior Hueso to laugh.
“I do hope the lovely couple enjoys their meals tonight.”
“Get out of here!”
Senior Hueso left the table head held high as he laughed, Leo slumped in his seat a pout on his face. You smiled softly gently nudging his leg with your foot under the table, “He seems lovely,” You hum, “I can see he cares for you.”
“Yeah right.” Leo scoffed, “Attempting to steal and ruin my date totally screams he cares for me.”
“Oh hush now,” You mused, “he’s acting like your dad.”
“What?” Leo choked sitting up straight, “Fuck off.”
“I’m serious!” You smile opening up the menu, “He’s teasing you the way a dad would.”
“God if that’s how he’s acting I don’t want to even attempt to introduce you to my actual dad, fuck me you’re gonna get harassed.”
“Stop.” You laughed, “You’re being dramatic now, I’m a big girl I think I can hold my own against my boyfriend's dad.”
“Oh? Have I made it to boyfriend status already?” How quickly Leo was able to change the subject never failed to give you whiplash.
“Shush you know what I meant,” You scolded without any fire behind your words cheeks a lovely shade of pink covering part of your face with the menu.
“You’re so cute do you know that? Like wow, I can’t believe I’m here with someone this cute?” You squeaked shyly and that only seemed to encourage Leo further, “Seriously though, you’re intelligent, and laugh at my dumb jokes. What else could a guy want?”
“Just pick your food already!” Leo snickered but did as you asked, dinner went by surprisingly well with pleasant conversations and good (but some odd-looking) food. You weren’t bothered by Senior Hueso again, you think maybe Leo lied when he said he needed to use the restroom and instead went to talk to the poor man. By the end of the dinner, you glanced at him, “So can I ask you a stupid question?”
“There is no such thing as stupid questions. Unless your Mikey.” You puffed out your cheeks and sent him a look, “I’m joking! Obviously…”
“So…what are…the mutants here considered?” You winced at the trepidation in your voice, Leo smiled gently,
“They’re called Yokai. They were born like this, mutants are what my brothers and I are cause we were turned using DNA when we were little.”
“Gotcha,” You said softly “So would all the criminals popping up recently would be mutants too right? Cause they were also turned?”
“You’re getting it, Donnie wasn’t kidding when you said you were smart.”
“Oh please.” You scoffed with an eye roll, “I’m just using my critical thinking skills and connecting the dots. You wanna see smart put me in front of a chemistry lab,”
“I’d rather drink chemicals.” He stuck out his tongue at the thought of sitting in a lab, “unless of course, we’re talking a private lesson. With the proper motivation from a pretty lady, I’ll sit through anything.”
“Proper motivation huh?” You raised a brow crossing your arms in front of your chest, “Now what exactly would be your proper motivation.”
“Oh, dirty girl making me talk about my fantasies in public you little minx.” He wiggled in his seat as you turned red, “I’m thinking nice little lace lingerie with only a lab coat on. Maybe some fake glasses, the stern but dirty teacher roll.” He cooed seemingly only watching in delight as you got redder and redder. “I’m thinking blue lace-”
“Leo please.” You pleaded fanning your face with your hand, “I’m a simple girl with simple desires you’re gonna make me pass out.”
“Such an innocent princess.” He snickered leaning over to brush his fingers against your burning cheeks, “Don’t pass out on me now we still have a long night ahead of us.”
“You plan on keeping me all night long Leo?”
“Hm…not all night. I know you have classes tomorrow, considering Donatello reminded me about a thousand times.” He muttered the last part under his breath but you caught it and laughed.
“He’s always looking out for me and my studies. He told me no girlfriend of mine is going to graduate without top marks.” You mimicked his brother even doing an exaggerated eyebrow raise which caused Leo to chuckle, “I’m glad I can rely on him.”
“Obviously.” Leo mused, “As much as we bicker there is one thing we all can agree on. Do you have any guesses?”
“Me…?” You whispered softly eyes glowing slightly in the dim light of the restaurant making you look innocent and tantalizingly irresistible.
“Ding, Ding, Ding. We have a winner boys, what shall the lovely lady get as a prize-”
“A kiss would be nice.”
Leo flushed to the tips of his mask he let out a nervous laugh, and you watched him awkwardly place his arms on the top of the booth. “Right, of course, a kiss. That can be arranged for sure…for sure, but erm…you’ll have to wait till the end of the night obviously that’s how these types of dates go after all.” You hid your giggles behind your hand as you nodded,
“Obviously.” You did your best to look as serious as possible while saying it because Leo looked like his face was going to melt off by how red he was.
He cleared his throat before responding in a much softer tone, “You ready to get out of here?”
“Did we even pay?” You asked, “I can pay for half-”
“No need Hueso’s gonna put it on my tab.” Leo waved his hand casually, “Before you ask the only reason I have one is that there have been times duty has called before I could pay. I do pay it off,” you bit your lips slightly and Leo chuckled, “Don’t worry about the price sweetheart I’m taking you on a date. I would never have you pay even for half, it’s my duty as a gentleman.”
“Alright, alright fine Mr. Gentleman.” You laughed with a shake of your head, “How many dates have you been on that the good guy gentleman act works for.”
“Hey now, what’s that supposed to mean? I am a gentleman always-” You shot him a look as he flushed once more, “It’s a 50/50 shot if my partner likes the gentleman persona or not. I can usually tell and adjust to fit what they like…anyway we should get going.” Leo stood up before you could comment on how that wasn’t the healthiest method to score yourself dates. “Ready for part dos?” His eyes had an elated shine to them and you couldn’t help but take his hand with a nod. “See you later Hueso!” Leo shouted over his shoulder opening another portal in the middle of the restaurant, you could hear faint cursing in Spanish as Leo dragged you through the portal. The both of you stumbled out of the portal Leo was laughing as you clung to him feeling the cold air of New York hit your cheeks, and your date settled you on your two feet. “You alright? Not too dizzy or anything?” He stood in front of you hands cupping your chin, looking into your eyes for any signs of nausea.
“I’m fine,” you smiled, “Just some vertigo but it’s already passing.” You reassured nuzzling into the palm of his hand. He smiled softly before sliding behind you and covering your eyes with his palms. “Oh? Is this a surprise?”
“Absolutely, I wanna see your reaction when I show you the amazing setup that I created.”
“Oh? Did you set this all up? How do you know some dumb kids didn’t destroy it?”
“I’d be very concerned if that was the case. Considering we're on the roof.”
“Well, now I’m concerned you’re gonna push me off.”
You laughed as Leo made an indignant sound of protest at the mere idea, “Even if I wanted to stage your elaborate death. This isn’t the way I’d do it, it would be such a boring way to go! You deserve so much more than that! I’m insulted that you think I’m that lazy. Plus Donatello would never forgive me.”
“Good to know you’ve thought about it.” You teased as he huffed behind you, guiding you wherever he planned to take you for the rest of the night.
“You ready?” He whispered into your air, his warm breath made you shiver, and goosebumps popped up all over your arms as your cheeks grew hot.
“As I’ll ever be.” You blinked a few times as your vision returned and your jaw dropped at the sight, it was a beautiful white canopy in the middle of the roof. It was decorated with what looked to be millions of different fairy lights all blinking in and out of existence. You could sense Leo bouncing on his feet behind you trying to gauge to reaction, the tent was surrounded by cute little plants all your favorites. Inside seemed to be filled to the brim with blankets and pillows and in the center sat a telescope. “Leo…”
“You like it right? Tell me you like it.” His fingers tapped anxiously on your upper arms, “You’re killing me here!”
“This is beautiful!” You shouted in delight, spinning around eyes shining in the darkness that made Leo’s heart skip a beat. “I think this is the most effort anyone’s ever put into a date for me,” you whispered cupping his face in your hands. He let out a loud purr-like sound nuzzling into your hands as you tapped his cheeks in absolute delight. “I’m so happy baby thank you!”
“I’m happy you’re happy!” Leo shouted grabbing onto your hips and pulling you flush to his body, “All I care about is your happiness.” He said it so sincerely it took you momentarily by surprise, he pressed his forehead to yours, “I was gonna make this all romantic and cute but…can I please kiss you?” The desperation in his voice sent a thrill through your body,
“Please.”
His kiss was different from Donnie’s, while Donnie’s first kiss with you was uncoordinated and messy, Leonardo’s was full of desperation and longing. But it was much more practiced and rehearsed this was not Leo’s first rodeo kissing, let alone kissing a human. Leo let out a whine pulling you out of your thoughts as you grabbed at the collar of his shirt kissing him back full force. He let out another sound, this one more pleased, as his one hand hovered hesitantly above the back of your head. You pulled away briefly, “It’s okay go ahead. You can touch me.” You spoke quietly and you saw Leo visibly shudder at your words,
“That’s dangerous.” Leo laughed breathlessly, “Don’t tempt me we haven’t even star-gazed yet.”
“We can skip that. If you want?”
Curse your absolute love for this dork.
“Skip it? And do what?” his brow furrowed,
Oh, bless this sweet, summer child.
You giggled softly tugging his hand and leading him to the blanket fort he had made, you had him sit down and he watched your every move with doe eyes. Leo tensed as you climbed into his lap straddling his hips and getting yourself settled on top of him, his hands instantly landed on your hips. His eyes widened finally picking up the idea you were putting down,
“Ough garoto, Donnie vai me matar…” He murmured under his breath, “reze por mim.”
“You okay? I can stop-”
“No! No, absolutely not,” He spoke hurriedly pulling you flush against his plastron, “Kiss me again.” It was a command, not a suggestion and shivers were sent down your spine, your fingers trailed up his cheeks before pressing a kiss to the side of his lips. The man whimpered under your lips and you couldn’t help but give him what he wanted pressing your lips to his own in a needy passion. Leo seemed to catch your drift at this point, his large fingers curled in your hair, seemingly more than eager to run his fingers through your locks. He tugged softly and you gasped quietly, he snickered and you bit his lips in response and he let out a pleased sound much louder than your own. So you continued to nip and bite at his lips and he melted under your touch, becoming completely complacent. He let out soft sound eyes screwing closed as you began to trail your lips down his face to his neck, and that's where you let your sneak attack begin. The gentle nips turned into rough bites with gentle sucking and Leo’s entire body shuddered as he exposed more of his neck to you, his noises got louder gripping your hips trying to pull you even closer. You were pulled so close that you were practically grinding on the bottom of his plastron like a dog in heat. You let out a few noises of your own as you began to rock against his shell, tossing your head back and squeezing your eyes closed. Leo took the opportunity to dive into your lips capturing them in a messy kiss his hands cupped your ass letting his fingers tap eagerly there. His fingers began to squeeze and kneed your ass urging you to continue to grind against him,
“Leo,” You moaned loudly your breath fanning across his flushed face his pupils blew side and he let out a sound.
“Okay woah, woah, woah,” Leo panted gently urging you down as you let out the most pathetic whine he’s ever heard, your thighs squeezing together. “Sorry, sorry,” he blabbered “Need a second I’m gonna-I’m gonna drop if-”
“That’s fine,” Your face red eyes completely hazy with lust, lips moving back to swallow his own.
“Ough boy. Oh dios mio- okay.” His hands began to tremble, as he put you down in his lap with a trembling breath. “I’m not, not on a rooftop at least. I need to be a little more suave and gentlemanly than that for our first time,” he cursed a little seeing you pout miserably as your thighs squeezed his legs watching you slowly drop as a panicked thought occurred to him. “But don’t call Donnie later to help or something-”
“Leonardo,” You groaned furrowing your brow, “Are you seriously asking me not to get off?”
“Maybe?” He winced cheeks a deep red, “I don’t know I’ve never been with a human before!” He blurted shyly, “I…I could try. I want to at least help…”
Your fight drained from you and a warm feeling settled in your gut, “We don’t have to go, farther, than you're comfortable with.” Leo nodded although you could tell he was sweating buckets, you reached out your hands and tapped his cheeks a few times and he let out a relaxed churr. “Trust me,” You pressed a kiss to the side of his lips, “follow my lead,” You took his hand within your own giving it a gentle squeeze. You brought his hand to cup your breast above your shirt, he gave his hand a tentative squeeze,
“Honk.”
“Did you just honk my breast?”
“I panicked!” Leo let out a panicked sound removing his hand as if your boob had burned him, he never wanted to spontaneously combust more than at that moment. You laughed softly,
“You’re a dork. Alright, I’ll skip the fluff stuff, Mr. Suave.” You teased sarcastically as he huffed, you leaned back and popped open the button on your pants, which seemed to perk the slider up considering the way he swallowed thickly.
“Holy shit.” He oogled the piece of flesh exposed and eyed the little blue bow on your underwear, “You wear these just for me princess?”
“Can it turtle boy I’m going to get myself off without you, or better yet I’ll call Donatello-”
“No, no. Show me I’ll be good.” He spoke a desperate edge to his voice thrilled you, what a good time day to be a switch, “Please.”
“Well since you asked so nicely baby.” You purred bringing his hand down to your sternum and letting it drag down till it reached the lace of your panties. “Under or over?”
“I get to pick?”
“Hmhm,” You almost whimpered trying to rock against his leg and hand, “Please ‘Nardo, need you.”
“F-fuck under then, yeah definitely under.” You didn’t have to help him guide his fingers underneath he was able to accomplish that task all on his own. He poked and prodded a little until he hit just the right spot and you let out a choked-out gasp, his eyes lit up at the sound.
“Yeah, b-baby right there.” You urged breathlessly, he gave your clit a gentle rub and your body arched eagerly in response. “F-faster than that you can do it,” Leo listened to your instruction intently you moaned head resting against his shoulder panting against his skin. “Leo,” you rocked your body against his fingers and squeaked as you felt one penetrate you. Ever so gently it slid in and it was BIG, you clamped down around him letting out one of the most guttural moans you’ve ever made. “Leo right there don’t stop. If you stop I’ll break your fingers,” You threatened, as you humped your body against his digits, one of them stayed dangerously close to your clit.
“You’re doing so good. Fuck you look so hot,” Leo laughed verging near hysterics “Cum for me. Please I’ll beg you if I need to-” You felt your tongue lull out of your mouth before you bit into the flesh of Leo’s skin, you both made a pleasured sound as you came around his fingers. White spots danced across your vision, as you fluttered around Leo’s fingers. You slumped against his body as you recovered from your orgasm, breathing heavily against his skin.
“You alright?” You asked weakly after a few minutes, he slowly removed his fingers as you jolted at the overstimulation. “Leo?”
“Holy shit human women are fantastic,” He murmured staring at the slick dripping from his fingers. You flushed,
“Dude! Don’t the mutant women have vaginas-”
“You’re the first woman I’ve gotten this far with.” That made you pause before leaning back to readjust yourself, “Does that bother you? Me mostly being with men?”
“No, not at all. I’m just amazed you’re this good for your first try with a woman,” You smiled pressing a kiss to his cheek. You rested your forehead against his a dazed smile on your cheeks, and you felt him relax from your words, “I think I left some marks on you…”
“Hot.” Leo breathed smiling goofily whipping his hand on the blanket, “Also, I’m glad I got rave reviews, I live to please. So in comparison to Donnie…”
“We are not having this conversation, Leonardo.”
