All 4 One
Welcome! I am so excited to share this with all of you. For a long time, I've wanted to try my hand at writing something involving the mating season HC that many of us have for the Bayverse Turtles (and the other versions). I also wanted to try the 'reverse harem' archetype with all four turtles x one reader, not all at once, but each with their own chapter and I'm impatient so I'm posting them all.
Mating season HCs that will be present in this story:
Can smell arousal and fear.
Will scent-mark you.
Become more feral, possessive, succumbing to their baser instincts.
Do hand fluttering on your face.
Have a preference for water.
Have an innate need to ‘breed’ you, especially if they know you’re ovulating.
Some of them might try to bite you.
Warning: This story and subsequent chapters feature aged-up characters. The pairing is all four of the brothers x one reader who is biologically female. Smut will be present in the next four chapters. Sexual acts between two consenting adults, MINORS DNI.
Special thanks to everyone who helped me come up with ideas for this, and to my beta reader, @adebauchedsloth, for taking on all 33 pages of this. You are all amazing. This story is dedicated to all of you. To the heathens, you know who you are.
Full chapter under the cut.
Your friendship with the four terrapin heroes started nearly a year ago.
Originally, like many others, you were simply a fan of the mysterious mutants who called themselves ‘ninja turtles’. You’d never actually seen them, only blurry photos, and many believed they didn’t exist. A complete fabrication of hope, an urban legend like Bigfoot or the Mothman. You knew better, firm in your beliefs. To you, they were as real as the wind that ruffled your hair or the sun that warmed your skin and made you sprout a few more freckles than you’d like.
You were so firm in your beliefs that you launched a podcast in the spring, which highlighted their many feats and heroic deeds. And when the famed April O’Neil agreed to guest star on your podcast, you nearly fainted right then and there, narrowly avoiding dropping your phone as you read the email over and over.
You’ve seen all of her news reports. After the Krang attack, she’d named those responsible for saving the city: Leonardo, Donatello, Michelangelo, and Raphael. You’d give your right arm just to be in the same room as those four, and this might just be your chance.
To your absolute delight, and hers, the podcast episode went swimmingly, ending with you and April laughing and chatting as if you’d been friends for ages. It truly felt like you were kindred spirits, sharing the same outlooks and beliefs. You were unaware that April, as clever as she was, had a secret ulterior motive. When she asked if you’d like to meet up with some of her friends, your heart almost stopped. No, you couldn’t allow yourself to hope for that, as if it would actually be them.
Yet, you couldn’t help but feel a spark of hope when she suggested you go up to the rooftop with her, your heart pounding as you followed her up the stairs.
You heard them before you saw them, a mix of differing male voices, all conveying a range of emotions from apprehension to excitement.
“See?! I told you April would introduce us to her hot friends!”
“Shut up, Mikey!”
“Ya gonna scare her away, dingbat, shut it.”
“I’ve been listening to her podcast since May, she really knows her stuff, we’re well, we’re like her heroes.”
“Hopefully, she’s not too ‘starstruck’, it would be nice to have more humans treat us like normal people.”
“Guys, chill,” April had reached the top by then, with you in tow. “She can totally hear you.”
Finally, laying eyes on them, you tried not to fangirl over them too much, but holy hell, they were magnificent. Four large silhouettes illuminated by the city lights behind them. You were stunned, taking them all in as if they were the angels of salvation they seemed to be.
April introduced you to them with a subtle little grin on the corner of her lip. It was rare for her to do anything that didn’t serve some purpose for herself and them. This was no exception. She knew her boys were lonely.
As expected, you hit it off with all four of them. Laughing and joking around with Mikey, discussing science and nerding out with Donnie, having formal yet intellectual conversations with Leo, and talking textiles with Raph. You’d actually just started crocheting recently, and he’d had more than a few tips to offer.
They all wanted to see you again, and after some in-depth discussions with Leo, they agreed to be individual guests on the podcast. They had been interested in the possibility of living alongside humans and thus began the integration process.
It was a perfect, low-risk way to introduce them to the public one at a time. Listeners could call in to ask questions or leave comments. Raph’s interview, in particular, attracted many viewers with just his voice alone. You received more than a few comments asking him to say a few lines from one of the more popular romance novels.
You would declare those sessions a success, and the next step was to do a recorded interview with one of the news stations. April was already working on that.
Besides working together on the podcast, you started spending more time with them. Sometimes one-on-one with a brother, or all four together. As you got to know them and became friends, you realized just how special each one was. Each had unique qualities, and instead of gravitating toward just one, you wanted them all to receive equal attention.
So, you did.
With Mikey, it was all about video games, cooking, baking, and making you laugh so hard you could barely breathe. His carefree, flirtatious nature was charming, and he always did his best to lift your spirits and make you smile. He loved his ‘pet names’ for you, too. At first, he was all over the place, calling you ‘babe’, ‘angelcakes’, ‘beautiful’. It was as if he needed to allow himself to believe that you were going to be a constant in his life before settling on the perfect nickname for you.
One day, he saw sunlight streaming through one of the grates above their home, bathing them in a radiant glow. From that moment, you became ‘Sunflower,’ feeling both humbled and pleased that you’d earned this special term of endearment.
His brothers followed suit. In fact, once the nickname stuck, the other three decided to come up with their own sun-themed nicknames. Raph called you ‘Sunny’ for the most part, switching to ‘Sunburn’ when you were playfully razzing him about something. Leo called you Sunshine, simple and with a tenderness that made you feel like melting. Donnie, of course, added a scientific twist to your nickname; sometimes it was ‘Sol’, Latin for ‘sun’, and other times it was ’Sunspot’. It was more nicknames than you could have hoped for, and you loved them.
Once Raph’s trust was earned, you were given an exclusive hall pass to discover a few of his lesser-known interests: his love for musicals and penchant for fruity mixed drinks, especially those that fizzed and tasted of strawberries. He was secretly a total sweetheart, leaving small surprises for you to find—tiny tokens of friendship like your favourite Starbucks order or a chocolate bar hidden where he knew you’d spot it. He also taught you self-defence and knitting, providing crochet patterns as well to expand your skills.
Leonardo took the longest to open up to you; he was very closed off and guarded at first. Overprotective didn’t even begin to cover it, but he trusted April’s judgment and very much wanted to give you a chance. It didn’t take too long, though. He had to admit, you did have a compelling way about you. With every joke you told, your cute laugh, and the way your eyes crinkled when you smiled. He found himself making excuses to be near you. Instead of in the dojo, his morning meditation had been moved to the spot where you liked to have your tea and read. He also completely took over brewing tea for you and saved his best blends for your visits.
While Raph was teaching you self-defence, he taught you meditation and tai chi. He showed you how to brew the perfect cup of tea, introduced you to all of his tea pets, and gave you the gift of peace when everything felt out of control. You admired his quiet appreciation for nature and all things Zen. Now you made a point of trying to be near him and meditate with him a few times a week. If it were up to him, it would be a daily occurrence.
Donatello was both shy and hopeful when you started coming around. At first, he’d convinced himself that you’d be completely uninterested in his projects and kept to himself during those first few weeks. Unfortunately, this approach left you confused and led you to believe that he didn’t like you.
When you confided in April about this, she quickly set you straight. Donnie just struggled a bit to express himself, but you owe it to yourself to try again with him. He was a sweet guy; he just needed a little encouragement, and she had the tools to help you draw him out of his shell… figuratively, of course.
The next time you found yourself in the lair, you were armed with confidence, fancy coffee and strawberry Pop-Tarts. Once the two of you started talking and you showed interest in one of his projects, he was fully and completely enraptured by you.
Little by little, you had built strong ties with all four of the brothers. What started as small sprouts of connection had grown into something that might have gone beyond friendship.
Like the shining yellow star that inspired your nicknames, a spark of hope had ignited. There was just one problem: you didn’t only have feelings for one of them, but for all of them, and this admission both intrigued and frightened you.
At the very least, you needed to sort out your feelings and determine whether one or all of them had feelings for you in return.
There was just one issue.
In mid-spring, about a year after you met them, they suddenly cut all contact with you; by all accounts, it made no sense at all. You felt both confused and heartbroken, desperate for answers. April was vague about the details; they just did this every year, and you shouldn’t worry. In about eight weeks, they’d be back as if nothing had changed. Eight weeks?! There was no way you could endure these feelings for eight weeks.
In your defense, April never told you not to go down there. But you needed to get to the bottom of this, and you didn’t want to wait two months to do it.
Before you could solidify this decision, fate decided to force your hand. While running an errand, your apartment, along with a few others, was broken into, and a bunch of your belongings were stolen or damaged. It wasn't anything with sentimental value, but electronics like your game systems and TV. Police were called, and you were advised to vacate your apartment for at least a week while the investigation and repairs took place.
While packing your bag, you realized you could stay with April, but there was only one place you wanted to go, and it was high time you paid a certain four turtles a visit.
----
The lair was eerily silent when you stepped through the doorway and set your bag down. Usually, it was a hive of activity with Mikey at his game station, Raph at the weights, Donnie typing away madly, and Leo training or relaxing with a book.
“Hello?” It was a hesitant call, because you half believed they might have really gone somewhere this time and wouldn’t be back for about forty-two days.
A flicker of movement caught your eye as you finally spotted one of them. Mikey had emerged from the bathroom holding a box of tissues in one hand and a bottle of lotion in the other.
He froze when he saw you, panic evident as he nearly dropped those two items, juggling them before catching them.
“S-Sunflower?! What are you doing here? Didn’t April tell you…?” You watched as he shuddered, inhaling deeply while tightening his grip on the items in his hands. “You need to go. Now.” His voice was a low, warning tone that had every one of your senses on alert.
This must be what prey feels like, yet you were unable to make your feet work properly.
“Mikey? What is going on? Why do I—"
The speed at which he reached you was inhuman. Something very strange was happening; this wasn't the Mikey you knew. No, he had gone on a vacation. This Mikey… was something completely different. He’d dropped both items and pressed you against one of the bricked-up walls surrounding the lair.
“Mikey…?” you sounded hesitant, scared even as you felt him lightly tap his fingers against your cheek and bury his nose in the crook of your neck. “What are you—”
He was rumbling, chuffing slightly as he rubbed his snout on your skin. A gasp escaped your lips as you felt his tongue dart out, tasting the salty sweetness there.
You heard him muttering, trying to press himself closer to you, while continuing to keep his mouth against your pulse point. “Shouldn’t be here… shouldn’t have you around right now… but you smell so good…”
If you weren’t so taken aback by whatever was going on here, you’d probably have considered this to be teasing, but Mikey clearly wasn’t himself. He was normally completely respectful, not… animalistic like… oh no.
He was kissing your neck now and pulling at the collar of your shirt to reveal more skin.
“Mikey, stop—wait.”
A deep growl startled both of you. Mikey lifted his head but stayed put, holding you tighter as if you were his catch of the day, and he was ready to fight tooth and nail for you.
“Let ‘er go…”
The voice was Raph’s, but it didn’t sound quite right, either, and when you craned your head to see around Mikeyyour only thought was holy shit. Raph looked positively feral. Being the biggest and strongest of his brothers, he looked downright terrifying right now.
“Back off, Raph! She’s mine… she’s already got my scent all over her.” Though Mikey was smaller, he showed not a single hint of fear as he challenged his brother for you, as if you were his prize. Your heart was pounding as you ran through the possibilities of what that meant, and who would be the victor.
With another menacing growl, Raph took a step closer, and Mikey snarled and hissed in response. His refusal to back down was causing you to panic. Shit, this was really happening. What if they killed one another?!
“Stop it, both of you.” Leo’s no-nonsense voice cut through the room like a blade before the sunset duo could begin their brawl. “Mikey, let her go. Now. She’s scared.”
Reluctantly, as if it pained him to do so, Mikey, seemingly regaining composure, finally released his grip on you. He sheepishly grabbed the bottle and the tissue box before stepping back cautiously. It was quite interesting, as he did so in a way that kept his shell turned away from Raph, intentionally showing he was not retreating in a submissive manner.
You released all the air in your lungs, finally, while looking accusingly at all three of them. “Somebody better tell me what the hell is going on. Right. Now.”
“I can help with that.” Donnie’s quiet voice piped up. You hadn’t seen him emerge, but he looked rough, all of them did, in fact. Completely wound up and exhausted-looking. You could see that even Leo’s shoulders were tense, and the muscles bunched uncomfortably.
“Spring is…mating season for turtles. It’s when we… well, we have the urge to mate, and we can get territorial and ‘grumpy’. Didn’t April tell you?”
No, she did not, and you were going to give her an earful the next time you talked to her!
“No… all she said was that you’d be back in less than two months, and I was worried; you all ghosted me.” It had hurt you, and you’d been worried and confused.
Your admission had them all looking a bit guilty.
“We didn’t know how to tell you.” Raph’s gravelly voice cut in. “Didn’t wanna scare ya considerin’…”
“Shh! Raph!” Mikey looked panicked, as if his brother had been about to reveal some kind of key information that had you intrigued.
“Stop it, both of you. We agreed that after the season would be best.” Leo said, silencing them both. “Sunshine, you'd better go. We can’t be entirely responsible for our actions at this time. Our baser instincts are…hard to ignore.”
All of the pieces were falling into place. Sex. They wanted it, needed it, and having you there, it was like dangling a piece of meat over a hungry lion—just out of reach.
“Oh…” was all you could manage while stumbling over your words. “I-I’m sorry, I didn’t mean to—I can go but…”
Leo looked visibly relieved, but pained; in fact, all of them did. You were beginning to realize that they wanted the choice to be them but refused to admit that.
You had more questions, you wanted to know more, to confess your feelings, but maybe now wasn’t the best time, not when they were in their current state of mind, but the fact remained, you had nowhere else to go.
“I… can’t. My apartment was broken into… I was hoping to stay here for a little while.”
Four pairs of eyes widened, and a collective, “What?!” pierced the silence as they all started talking at once.
“Did they catch the guy?! I’m gonna kill him…”
“I told you I needed to set up some security there…”
“Omigosh, Sunflower, are you okay?!”
“Well, that settles it. You’re staying.”
You were all staring at Leo now, the last one to speak and make this declaration.
“Whoa, wait, Leo, are you sure about this?!” Don’s voice had gotten all squeaky with worry, and there were similar expressions of uncertainty on his brother’s faces as well.
“We would need to set some ground rules, but yes. We will not be abandoning her in her time of need.” Leo said firmly.
“This is a bad idea, Leo…” Raph was extremely doubtful; he knew how strong the urge to mate could get. Already, he was having difficulty with you and your sweet scent being so close. Unfortunately, Mikey’s was there too, but he was confident he could erase that and replace it with his own.
“Raph, this is final, it’s just a week, we can keep to our rooms.” Leo was not budging on this, and he fixed his brother with a look and a slight growl.
Raph looked slightly cowed but crossed his arms stubbornly. No further protests were voiced.
Mikey just looked both nervous and excited at the same time.
“Hold on, I think I might have something that will help.” Donnie disappeared into his lab and returned with a small box in hand. “These are... tranq darts; piercing our skin with one of these is enough to knock us out for several hours, Sol.” He was speaking to you directly now. “I think you'd better sit down because if you’re staying with us, you’re going to need a quick lesson on turtle mating season 101.
“…Okay.” Already, you were getting a little nervous. What kinds of instincts would necessitate the use of tranquillizers on these guys?!
Donnie, at his word, delivered a quick, concise explanation of their mating season. Their baser urges were strong and hard to control but in no way would they put your safety and comfort at risk. To keep you safe, you were instructed to carry the tranqs, and they would work out a schedule to keep you from staying in the same room with any of them for too long.
This could work… could it? You weren’t so sure.
Your first night was quiet, and you lay in the spare bedroom with only your thoughts to occupy you.
Would it really be so bad to let yourself have a little fun? Stop that, they explicitly told you to stay away.
I bet they’re just jacking off non-stop.
What if they’re thinking about you when they’re doing that?!
Actually, that’s kind of hot…
You sat bolt upright in bed, red-faced and ashamed of yourself. You weren't going to take advantage of them while they were in this state! You could do this. You had to.
Your resolve lasted about two days.
-----
You summoned the four brothers to the kitchen as you nervously paced just beyond the long counter where the four stools sat empty.
They all looked perplexed as you tried your best to articulate your feelings.
“So, it’s like this…for a pretty long time now, I’ve had… feelings, and not just for one of you, you’re all really special in your own way, and I feel like I’m making your season worse by being here, and if you’re suffering right now because of me, then I wanted to… I want to help you with that.”
They gaped at you. Mikey looked absolutely elated at this prospect, while Raph scoffed audibly in disbelief.
“Sunny… you got any idea what you’re offering?”
“Yes, and I’m aware of where my offer might lead. I hope you know I am not trying to take advantage of the situation here. We can keep the current arrangement, I just wanted you to know.”
“You’re not…making it worse,” Leo spoke up. “Admittedly, your presence is… distracting.” He was attempting to be polite about it, but you knew better. “But we can manage, you don’t have to… offer yourself up like this. For your own safety, I think we’ll have to refuse.’
Donnie was next, his glasses seemingly flashing a little as he looked your way. “Logistically speaking, Leo, having a possible ‘mate’ might not be a bad thing, if she’s willing of course. The issue would be preventing us from fighting and performing displays of dominance to essentially… win her favour.”
“We could take turns.” Mikey shrugged, convinced the simplest solutions were the best. “And if one of us does something she doesn’t like, she can always jab us and be done with it.”
“If she has to jab any of us, then the whole deal is off, and she stays with April until her apartment is fixed,” Leo said evenly. “But, I believe first we need to make something clear before this goes any further.”
You waited, nearly holding your breath to see what they were about to say.
“Well, to put it simply…”
“We ain’t just sayin’ it cuz it’s the season.”
“Leo wanted us to wait to tell you, but—”
“We like you too!” Mikey finished.
“But I’m not sure if this is the best way to begin a relationship.” Leo fretted. “We’ve never had a woman around at this time…”
“Leo,” you calmly interjected. “I think Mikey’s right, we don’t need to overthink this, we can take turns, work out a schedule for the next four days and then at the end of your season, we can reassess whether a relationship with all four of you could work.”
“Kay… then, who’s first?” Mikey’s hopeful voice piped up, cutting right to the chase.
Leo didn't look convinced; frowning, he kindly asked you to return to the spare bedroom so they could talk amongst themselves. You complied easily, though you might have been second-guessing your suggestion. Perhaps it was wrong of you to ask and burden them with this.
“Why are we even talking about this, Leo? If she’s DTF, who are we to stop her?”
“We might not be at each other’s throats at much if we are getting our needs satisfied by an actual woman.”
“She was into it, bro, she wouldn’t have suggested it otherwise.”
“I think you’re all forgetting about the fact that this is our friend, not just some random woman offering to help us satisfy ourselves.”
The other three were quiet but determined, a brief moment of clarity in the haze of their lust-addled brains.
“We know that, Leo. We were all just discussing what a possible relationship with her might look like. Ain’t just any girl who would willingly hang out with us.
“And technically, we’ve gotten very close with her already. She’s found a fair reason to move things along to the next step. It just happens to be during the season.”
“Well, I dunno about you guys, but I love her, I’d never do anything to hurt her. This is why I should be first.” Mikey declared proudly.
Leo just uttered a deep, long-suffering sigh. “We all have strong feelings for her, but I want to make things perfectly clear: if any one of us does hurt her, accidentally or not, we could lose her forever. Are we all willing to take that risk?”
Raph simply shrugged his shoulders. “Yeah, cuz something like this ain’t gonna come around again for as long as I live, and I’m not gonna give up this chance. She’s special.”
“She’s got the tranquillizers, and she’s in a clear state of mind. Really, it’s up to us, and I’m good with it. I propose twenty-four hours each, and on the fifth day, we reassess the findings.”
“She ain’t an experiment, Don, what the hell are we gonna assess? How many times we made her cum or somethin’?”
“A whole twenty-four hours, shit, man, that sounds totally awesome! Please, Leo, please?”
A long moment passed before he finally acquiesced, “Very well, but we’re drawing straws to decide the order first. No arguments, fights, or displays of dominance. We stay in our bedrooms as much as we can when it isn’t our turn. Is that understood?”
The only times they’d need to leave were to eat, and with a schedule worked out, it was unlikely you’d run into each other; luckily, all four had their own bathrooms. You had free rein; it was unfair to think you wouldn’t, since you were willingly putting yourself in the situation. Still, the worst that could happen was they got grumpy and territorial if they crossed paths.
Later, you’d reconvened in the kitchen again and carefully laid out the terms of the agreement and everything it entailed. You agreed, the straws were drawn, and the results displayed.
“Hell yeah!” Mike crowed, delightedly clutching the longest straw.
