This is a smut fic, read at own risk. dom!Reader+sub!SH Tails • Dry humping • Use of the term ‘mommy’ but gender is not specified otherwise • Climax mentioned • Tails being vocal

Tails was so overwhelmed.

He wanted you to be proud of him. But as soon as you turned around to leave and allow him to rest? he couldn’t fight the urge anymore: He needed you. Tails didn’t even hesitate, he just lunged forward out of the bed and pushed his body up against yours, ramming your back into the nearby wall. He wanted to be closer, so much closer... He wanted to know what it felt like to be used. All the time he couldn’t talk to you, was all the time he wanted to touch you...

You couldn't help but let out a gasp as he practically launched himself at you, pinning and cornering you into a wall. But despite your shock, you managed to keep a grin on your face. You raised an eyebrow, letting out a faint laugh as you spoke out to your fox partner, putting your hands on his chest to create a little bit of distance.

“Ah... Do you need anything?”

At that moment, Tails could smell your hair. It smelled very… attractive, and familiar. The mobian’s legs went weak as he was close to you. And especially when you rubbed your thumbs on hi, Tails’ face flushed up. He felt so weak and so comfortable in your presence… As if he could literally die of happiness in your arms.

“More…”

He whispered softly, as his eyes widened while staring at you. He needed more.

“more?” You repeated in a tone of question, cocking your head to the side with your smirk expanding a little. “i'm gonna need you to elaborate, my sweet, sweet boy” Your voice rang through the room along with a snicker, directly confirming that you were playing dumb and hard to get, but you had still tried to keep it cool nonetheless. Your fingertips began teasing the fur on his chest, pressing through the coat and circling around on his hot flesh.

Tails let out a small, but loud moan of pleasure as his body was being massaged by your sneaky fingers. He was so turned on right now. And it was the most confusing sensation to him. He felt so wrong for wanting you right now, but he couldn’t even try to resist.

“More, mommy...” Tails whispered. He wanted you to know how good he felt, especially when he said “mommy.” Resulting in you letting out a little ‘hmm’ for joy, smirking to yourself as you leaned in a little. You stuck out your tongue, placing your arms around his shoulders in order to keep him in place. It was quiet other than his heavy breaths, fogging up the place as he panted like a dog.

Though without warning, you pressed your bottom onto his with how close they were, teasing him even further. “like this~?” you purred out, as you grinded your hips onto his lower half, knowing he couldn't do a damn thing about it. And as expected, he once again let out a loud moan as you grinded your body on him.

You were playing this game with him, and he didn’t want to waste any opportunity he had. And so... he grabbed your hips and pinned you down against the wall, and began moving his hips slowly and rhythmically against yours, all the while biting away at his bottom lip.

“sweetheart, you're grinding on me...” you silently muttered, your free hand traveling towards the back of his head, caressing through his fur and reaching his scalp with your fingertips. You weren't necessarily uncomfortable by this outcome, rather just... amused. You ignored the moan that left him as you looked up from your pinned position. “You're going through... it ...aren't you? Do you need some help? Or are you just gonna dry hump me?”

you questioned with a hint of sarcasm and another snicker, not minding the fox in rut. A loud moan leaving his mouth as he heard your question with the obvious taunt. Your fingernails traced across his head, teasing him in the process as you gave him the exact same cocky grin.

“I don’t need help…”

He whispered in between his moans, feeling so humiliated. You were calling him out on something he was still confused about. Your words were also so teasing and he wanted to get back at you. His eyes were locked onto yours, along with his teeth gritting. He moved his hips even faster, getting desperate with the overwhelming sparks he felt in his lower region.

Which only made you snort in response, raising an eyebrow. “oh? You're trying to tell me that you don't require some help, hmm~?” you spoke out in a tone of sass and doubt as your fingers traced all over his body, now getting him even more bothered on purpose. From his shoulders, to his back, to his chest... You were all over him. And before he knew it, you gave him one single grinding movement of your own once again, allowing the warmth of your hips to get to him. And knowing a hopeless mess like Tails would do anything for the sensation at this point.

The moment you gave him that grinding movement, Tails let out a loud and long moan of pleasure that felt so good... His eyes widened and he took a deep breath in. He then moved his hips up and down rapidly and roughly against yours, and his grunts were loud. His teeth were gritting tightly, but in between the loud grunts he was making, he managed to call out to you.

“I don’t need help…!”

However, he still was looking up at you with those desperate puppy eyes... And your smirk just grew a little at that as you backed up, shrugging before you put your hands on his shoulders, pushing him backwards. “If you say so~”

You spoke out in a careless manner, before you yanked his hands off of you. “have fun with your itty bitty problem on your own then. Since you don't need help” your words being cold yet sly, which noticeably made him let out a pathetic growl in response. It were his words, not yours. He'd have to choose between his pride or you.

Tails was so turned on right now, that for a moment he started to get angry. But he couldn’t stay angry with you for too long. He was simply… overwhelmed by his love and lust. And he also still wanted to make you proud, so he simply…

Swallows his pride.

He went to you with a more gentle approach as he laid his head on your shoulder, and spoke softly.

“I need you to help me… mommy…”

This was it. Your shit eating grin reappeared on your face but there was also a hint of softness to it. You were practically melting. You leaned in with your head to the point you were right near him. You blew into his ear and he could feel the warmth of your breath on him, along with hearing a small giggle of amusement. Your free hand went over to caress the back of his neck, moving it up and down as you looked at him with prying eyes

“aww...~ good boy~” you spoke in your best and sweetest tone yet

Tails couldn’t even take it anymore. His breathing was fast, his heart was pounding, and his face was bright red with the drool leaking down his lips. And as you spoke those sweet words to his ear, he let out a vocal whine of pleasure, with his body just collapsing on your shoulder.

He was ready to beg for more. He didn’t even care about anything anymore. The fox just wanted you... your simple grip on him making him shiver with ease, as you held onto him in order to keep him balanced. And in order to reward him, you deeply pressed your bottom onto his groin area once again, returning the sensation in one go. The heat of your body temperature from down there making it so much more difficult for him to handle. Making it even worse so when you began rubbing yourself up and down on him.

Tails began to feel a heaviness on his pelvis... And the moment he felt it, he completely lost himself, he couldn’t handle it anymore. All the priority to keep his pride in check going straight out of the window. You could notice him getting wetter and wetter as time went on, indicating that he was close... feeling his fluids going right through your clothing, along with him becoming more whiny... more needy for anything. With him becoming especially vocal by you gently trying to ease him into it.

“You're doing so well, sweetheart...~” you complimented with a grin, before you sped up the pace of grinding your crotch against his. Keeping a steady grip on him and making sure he wouldn't fall onto the floor just like that, allowing him to rest on your body. You guided his head towards your chest as you put your chin onto his head, flattening his bangs. All while continuing to thrust your hips onto him, making him completely soak.

Tails rested his imbalance on your body, his face buried in your cleavage. He couldn’t handle how soft you were, it felt so amazing... And as you started to thrust your hips onto his, his body went weak, and he just started to moan and drool. He wanted this so much… But, he was getting so close to the limit, so he was holding back as much as he could.

But you were not having that... Making him gasp out and whimper as you grabbed him by the chin, forcing him to look up at you. You pressed your thumb on his chapped lips, making him let out yet another small moan.

“Shh...~ it's okay, sweetie. Will you release your tension for mommy~?” you murmured, keeping his groin pressed up against you and making him shake in his boots. Making a desperate attempt to make small rubbing motions on your body, but you sure kept him in line. And it was clear your plan was working with how moist he was getting himself, his fur now all sticky and wet...

He was so close, he couldn’t resist it anymore. He pressed his legs together as the warm feeling of you was beginning to make his body reach its peak. And he was so sensitive down there, and the wetness… Oh, God. It was so pleasureable. And just like that… he gave in.

“M…m…” He was so shy… “Mommy...” He whispered in a muffled voice, trying to hide his face in your chest. “good boy...~” you just gave him that last tiny push as you held him by his rump, before grinding him on you instead of the other way around. Pushing him against you deeply as you thrusted back in return, creating an even higher sensation than before. The two were like two connected puzzle pieces, and you knew this was really the last thing he'd need before releasing...

And as soon as you made your move, his eyes widened, and he started moaning really loud. His legs went weak, and he started kicking and trembling a little. He still tried to hold back, but, he couldn’t any longer: all his energy got drained immediately as his eyes rolled back, and he started to melt… like a mess. His fluids began to drip.

And as he did, his whole body went slack. You could literally see him go from mischievous and proud to weak and submissive. His body went all soft, and he melted all over you. The mess of fluids that dripped from the two of you was just… so perfect. He couldn’t even speak. He literally lost all of his words as he laid in shame.

Tails would do anything for you...

You gave a huge grin as he came undone and laid out like it was the end of the world. You took a tiny step back but made sure to still hold onto him so he wouldn't collapse, giving his arms a tiny squeeze. He was an absolute wreck. Tears were pouring down his face, with sweat stains visible, and drool was leaking out of the corners of his mouth. And don't even get me started on the festival down there. He looked like he just stepped out of a pond. And this only made it better for you.

Your little fingers massaged over his arms as you pampered him by giving these little kisses all over his face, seemingly not grossed out by the bodily fluids on his face. You even went out and gave him a smooch right on his mouth, allowing his leaking saliva to enter yours.

Tails was just so… humiliated. But he was so used to you having power over him in these private situations. He felt so much shame, but he felt so much love for you, simultaneously. Because you were the one who made him feel this way. And he knew he loved that. So… he was so glad that you found pleasure in his desperation. His body felt the best it ever did. He wasn’t just dripping, he was flowing. And he was completely yours... but...

You didn't seem to be done.

Right before he even got to say anything, you now pushed him against the wall instead, not allowing him the slightest bit of space. You balanced on one of your feet as you tilted up your other leg, right before pressing your knee right onto him again, almost making him choke and gasp out for air once again. Slowly beginning to give more pressure down there.

His legs immediately folded under him as you pushed your knee against his groin. Tails’ whole body went limp, his eyes rolling slightly. His eyes were locked onto your, and he could feel his mouth watering. Your grip on him increased, and he looked like you were playing with him. This time he wouldn’t be able to resist any of this… And he’d be your little pet again. This was just the beginning.

Your mouth went up to his throat as your teeth nipped him, taking his skin in between your side teeth right before letting it slip again, teasing him. Your weight leaned on him as you got into his personal space, the pressure of your knee making him feel turned on again... making him just as sensitive as before while you pressed him in between yourself and the wall, feeling his previous release drip down from your clothing.

You were so careful and gentle with both his mind and body. Tails being all wet like before, then you simply nibbling on his neck and then the heat of your body making him feel so relaxed, he felt like your own little toy. And he loved the fact that he belonged to you. The amount of pleasure he could feel… was unmatched. His hips began to move ever so slightly, which didn't go unnoticed by you.

The fact that he was trying to grind himself against you again was honestly one of the most pathetic sights you've ever witnessed, but you didn't mind. In fact, you were willing to give him a little gift for being so good before. You stood on your tippy toes and went over towards his ear, your breath audible to his senses making his twitch. You gave him one single grinding movement before stopping and whispering something in his ear..

“Go all out with your rut, my little beast~ I'm all yours~” you purred with a chuckle, giving him permission to what he wanted as you began biting at his left ear. You were still gonna take the lead, but you wanted to see just how much he'd do when given the chance to. How much control he'd lose over himself...

Just the feeling of permission from you was so strong for Tails. The moment you blew your breath against his ear, he couldn’t help but moan a little. And that was when he truly started to turn savage with his movements. His body became aggressive and animalistic. He started to moan and pant and he started to thrust rapidly and rough against you. This wasn’t just about him anymore though… It was about him and you. And you held complete control.

You had never heard the boy so vocal before, but you found amusement in how he was practically behaving like a wild animal for you. The mobian had no filter left anymore. Despite your silence in the duration of the act, the desperation on his face and the inhuman noises he was releasing made it much more enjoyable than you thought it would.

You both knew you were absolutely dominating over him the whole time he was going crazy on you, but the feelings he felt… were completely mutual. But at this point, his need to give you the satisfaction felt so strong that he was just giving into you completely. Tails started to cry out loudly with tears running down his face, and not caring that this made it even more arousing for you. He wanted to do everything for you.

And he was basically a vivid representation for your power over him.

'Best Friend.'

(Yan! Secret History Tails x Reader)

Note: Been obsessing over this little fucker so decided to write this down for fun. If you enjoy this, feel free to blow up my ask box as I would gladly write more for this stinkalink.

Word count: 4,593

Tw: Death, violence, worship, threats, attempted murder, and yandere behavior

(Y/N) never wanted to get wrapped up into all this, all they really wanted to do was just help an acquaintance in need, they never planned or even thought that the action could have any consequences, much less ones to this severity. Even now, with slick scarlet staining at their hands, they still are in shock, thinking it all must've been some crazy type of dream, but they knew better.

The night this all started was just like any other for (Y/N).

The morbian had just gotten off of their shift, with sore feet and a strained brain from hours and hours of work, their only thought was about returning to the comfort of their home for some much needed dinner and rest.

Their body was practically in autopilot, following the familiar trails of the sunset forest zone. Even with a lack of thoughts or cares, they still took the time to take the slightly shorter way through, cutting through the trees and actual forest part of the zone to avoid the obstacles that the land had, making it hard for anyone to really get anywhere without it being like a parkour course.

Of course people like Sonic, Knuckles and any other of his friends might've had no problems with doing a course like that in under 5 minutes and continuing with their day, but (Y/N) wasn't like any of them, they were painfully boring and on the weaker side of things unlike the colorful cast of heroes that they had grown to be acquinted with. So, for people like (Y/N), they took the shortcut.

(Y/N) trudged through the forest, gently swatting away any leave or tree branches in their way as they did so. The setting sun's golden rays warmed their body to the touch, making a relaxing, lulling feeling overtake the morbian, allowing for them to wash away the stresses and worries of the day.

They felt completely and utterly safe right there on the path, not worrying about anything, not having to worry if another villain appeared along their way, and not having to worry about the creepy customers at their work who made it their goal to make them as uncomfortable as possible and then leave a shitty tip.

It was nice to have no cares, being able to just enjoy yourself in a comfortable silence. Though, that didn't last long--Well, at least not the silence part of things. Just before reaching a clearing of sorts, (Y/N) heard some subtly shoveling noises coming from ahead, followed by muffled cursing. They couldn’t understand most of it, but they were able to make out the whisperings for "Imposter." and "Dirty cretin's."

Taking notice to the hostility in the raspy tone that they head, (Y/N) immediately halted all movements and stayed deathly quiet, trying to make out where the sound came from so they could avoid that area or find a way around it without running into any possible dangers.

Sure, they could've ran in trying to find out whatever this hostile person was and see what they were up to and if it were actually dangerous but (Y/N) did not want to stick their nose into any strangers business. Especially when that stranger is in the woods alone with them. That sounds like the start to a bad horror movie they did NOT want to be a part of.

The sounds seemed to be coming from straight in front of (Y/N), causing some difficulties for any escape plans. If they just moved far to one of the sides, the person or morbian behind the sounds would easily be able to see them, thanks to the fewer amount of trees near the clearing.

So, (Y/N) quickly crouched down and crept toward the direction the noise came from, carefully listening in on the voice as well as trying to peek at who or what was there to be able to plan out an escape route. However, they could hear only faint whispers and hushed curses. As they approached closer, the earth decided to give them a cruel reminder of their surroundings.

'SNAP'

They took a step further than they should've, and suddenly the noise of a twig snapping under their foot hit not only their ears but mostly likely the figure they we're spying on as well. The murmurings and shoveling noises came to an abrupt stop, confirming (Y/N)'s fears that the person had heard it.

Fuck.

In one swift movement, (Y/N) pushed themselves up from their crouched position, darting to the left to at least try to hide in the few of trees they did have while evading the thing that had made all those noises. They weren't sticking around for even a second longer to figure out what the hell would happen to the. They had a better chance of surviving by running instead dog staying put like a deer in headlights.

The sound of something heavy hitting the floor was not lost on them, and neither was the pitter patter of feet chasing after them. The calming feeling they previously held in their chest when strolling quickly turned to adrenaline and fear.

This person had to be bad news, they wouldn't have been chasing (Y/N) unless they had something (Y/N) wasn't supposed to see.

The exhaustion that previously consumed (Y/N) and alertness took it's place. (Y/N) pushed against the wind, running as fast as they could, to the point where the fear of their leg muscles tearing was an actual thought that crossed their mind. Their breathing became erratic, both due to the energy they were using up as well as from fear. Despite their attempts to avoid any other branches or other parts of the natural environment that could slow them down, mid-steo their ankle had snagged onto one of the trunk roots belonging to one of the few trees around, sending (Y/N) toppling to the ground.

With the force and momentum, their fall knocked the air out of the lungs. (Y/N) yelled out, cursing out as a sharp pain was spent through their knee, making their cab quickly cramp up. They tried twisting their body to force themselves back up but before they even could, a hand grabbed at their shoulder, making the morbian flinch and their blood run cold.

But the touch was...oddly gentle??

"Ohmigosh!! Are you okay? What are you doing out here?" A familiar voice fell on (Y/N)'s ears, a stark contrast from the shrill yet raspy voice that they heard from the harsh whispering earlier. (Y/N) whipped their head around, turning to come face to face with a familiar two tailed acquaintance.

"Tails?! What are 𝘺𝘰𝘶 doing out here??" Despite (Y/N)'s confusion, the morbian couldn't help but feel relieved at the familiar face. At least there was a hero here now, no one would dare try to chase after them if Tails was by their side. There was a high chance people wouldn't question their disappearance--But tails?? Tails was a part of Sonic's crew, people would definitely be worried if he left.

"I was just..Making sure Robotnik hadn't set off any traps here for Sonic. What are you doing here..??" He questioned with a tilt of his head, a curious look taking over his features. He moved his hand away, allowing (Y/N) to sit up which gave the Morbian a chance to inspect their own leg. (Y/N) took notice to how his lips parted at the end of his sentence, as if he was about to use their name but had forgotten or hadn't known it. They were hurt, but they couldn't really blame the two tailed fox.

The two had never really hung out alone before so there's no surprise he wouldn't remember them that well. "I was just going home from work when I heard something. Before I know it, I'm being chased off and now this." (Y/N) explained, gesturing to their leg as they did so. Tails' eyes followed where (Y/N) was gesturing, taking notice to the leg.

"Oh, geez. Can you move it??" Tails asked, a hand reaching out to inspect the leg and stretch it out to see if that could help. He placed his paw on the leg, his eyes held no emotion, despite how his face made an effort to contort in concern. He did some simple stretches on the leg, but it only took a few minutes for a noise of pain to escape (Y/N)'s lips, alerting the fox friend to the fact that it was most likely too painful to walk on.

"I'm no doctor, but I think you might have a sprain. I don't think you can walk with it."

He looked at (Y/N). "Do you need me to carry you?" Tails asked, offering them a soft smile. "I may not remember where your house is, but if you tell me I'm sure I can take you there."

(Y/N) considered it for a few moments, their brows knitting together as they did so. They didn't want to cause him any trouble by asking him to do such a thing but with the throbbing pain in their leg, they doubted they could limp all the way back to their home. So with a nod of their head they agreed on Tails's offer. "If..if you can, please." They answered quietly, a tired and exhausted expression taking its place on their face.

The two tailed friend grinned at this before adjusting where he was so he could easily scoop (Y/N) up. Once in position, the fox picked up the morbian with little to no struggle. The morbian fox quickly draped (Y/N)'s body around his shoulder, carrying them firefighter style similar to how someone would carry a dead body or unconscious one.

"Jeez...I uh...I don't remember you being this strong, Tails." A nervous laugh escaped (Y/N)s throat, their hands latching onto any of Tails to make sure that the furry fox wouldn't drop them.

"Well, Sonic isn't the only one whos been pummeling Badniks." Tails chirped out, to which (Y/N) made a noise of understanding, eyes still cautiously watching the ground to make sure that they wouldn't slip and land face first into it.

With (Y/N) now draped over his shoulder, Tails took off into the direction towards (Y/N)'s home--Of course, after the Morbian had told him the coordinates.

-------------------------------------------------------------------

"Thanks again, Tails. You really came at the perfect time." (Y/N) grunted, their bed bending when the two-tailed fox placed them down on it. Tails gave a small nod, his tail slowly swishing behind him as his hands hovered over (Y/N)'s figure for minutes longer, ready to grab at them in case they would fall back or the like. "It's no sweat off my back--After all, What are friends for??" Tails smiled widely, flashing the other with a cheeky grin.

(Y/N) laughed lightly at that, their mouth twitch upwards. "Friends?? Didn't know you considered me one. I'm honored, Tails." Tails rubbed the back of his neck nervously, though it didn't feel entirely organic, more so that he planned for the action, deciding what would look the best.

"Whoops, must've just slipped out, huh?"

(Y/N) hummed in response, their expression taking on a slightly troubled one after the warmth of the interaction rubbed off.

"Hey...Tails?" (Y/N) questioned, unsure in their words of they should say it.

Tails raised his head once more, his ears perking up and twitching at the sound of his name. "Hm? What's wrong??"

(Y/N) paused for a moment, before opening their mouth to speak.

"Do you mind if you stick around for a few minutes?? You don't have to stay the rest of the day or anything, I'm just a bit worried that...something had followed me from the woods."

Tails furrowed his eyebrows at this, his eye even seeming as though it we're twitching from annoyance, but the expression only lasted a split second and was barely registered by (Y/N) before it returned to the kind smile the fox always had. "You're right, of course. It won't bother me at all!! I'll stick by the front door to make sure no one comes by and so I can see if anything goes on."

(Y/N) flashed the short fox a grateful grin, words being incapable of expressing their gratitude towards his act of kindness. "Thank you so so much, I really appreciate it, tails."

Tails waved his hand dismissively. "Don't worry, it's no biggie!! Just worry about getting some rest for your leg, okay?? Once your safe and asleep, I'll just slip on out." Tails didn't wait much for a response, quickly taking his leave with a flick of his tails, leaving the morbian alone in their room, confused but still grateful nonetheless.

Once away from the morbian, Tails released a sigh, one of annoyance as he quickly dropped the kindhearted smile he kept plastered on his lips the entire time he was around that..that...𝘵𝘩𝘪𝘯𝘨!!

Who were they anyways?? His universe never had anyone like that, and neither did any of the other universes with the other fake 'Sonic's. It was always him and Sonic, occasionally Amy, and Knuckles as well but there was never someone of (Y/N)'s caliber--Much less one that seemed to be acquainted with Sonic and the imposter of himself.

It was disgusting. Why was this universe any different?? How could it be? It was never different. It always always the same, it was supposed to be the same. He doesn't like change, but he especially didn't favor this change.

The two tailed fox strolled down the halls, his eyes flickering from wall to wall with disgust evident in his gaze. What was so special about this person that Sonic would be wasting his time on them?? The only person he should be wasting his time on was him--His best friend.

Tails paused, his eyes falling towards a table just barely in his line of sight from the gap that lead from the halls to the living room then the kitchen. Curious, he made his way over to it, though most of his intentions was just to get to the kitchen, to grab a knife and finish the job to leave no witnesses.

On top of the table were some documents, just the usual rent and bills and things of the nature. He grabbed for the documents, bringing it closer to his face and squinting to try and read the finer details and possibly attach a name to his victim.

"(Y/N)...(L/N)..??" His voice muttered, dropping the whole impression of this universe's Tails to instead speak in his usual shrill and raspy tone.

It wasn't a...bad name. Not bad at all actually. Kinda had a nice ring to it.

He shook his head, clearing it of its thoughts before he tore his eyes away from the work, letting it fall on the walls instead--Or more specifically, the pictures on the walls. There were many photos of (Y/N) and family members but they weren't the ones that caught his attention.

The one that did was one of (Y/N) who appeared to be just a few years younger, their hair dawning on a slightly different style and they were grinning like an idiot with Sonic right next to them, taking the picture. It must've been the first time the two had met, (Y/N) looked as though they had just met a celebrity or something so it was a possibility.

Sonic looked so right in that image, almost reminding Tails of the Sonic he thought was the real one, the one from his universe.

Maybe this universe actually 𝘥𝘪𝘥 have the real Sonic, His Sonic. He might actually find him this time.

...

Maybe (Y/N) was the reason for that?? They WERE the difference that separated this universe from the many, many others with many, many imposters of Sonic that tried to deceive him.

That's how it all started.

After that, Tails had successfully replaced his 'imposter' and nobody were none the wiser. Sonic and Amy noticed that he seemed off at first and was able to get them off his trail. Amy even started to grow vulnerable enough to open up about her crush on Sonic and how to win him over.

Perfect.

That wouldn't be the last time he saw (Y/N), however. The day after, (Y/N) had showed up at his lab with a noticeable limp, having made him some food as a thanks for him helping their leg out. Tails--Although a bit begrudgingly, ended up helping the morbian out, making sure that they were able to walk around by making them a cane for temporary use until their leg healed up.

The plan originally was to get (Y/N) out of the picture, either by executing them in a similar style to how he did with Shadow and Knuckles sor through other means.

But when he finally had the opportunity to do such a thing by them complaining about how their phone was bugging out, he...didn't. He offered to help and had a chance to turn it into an explosive as he had done with Knuckles but he couldn't. All he did was fixed up the bugs as well as add some much needed upgrades before giving it back to the morbian.

He swore he never saw Amy or Sonic's eyes light up like how theirs did whenever he did similar favors for them.

He found himself spending hours and hours reasoning his behavior with himself.

Of course he couldn't kill them, they were the reason he was with his Sonic!! If he killed them, the universe would be just as interchangeable with all the others, than that wouldn't make his Sonic special.

The two grew a bond rather quickly. (Y/N) usually came over to check out any little projects or gadgets Tails was working on and Tails would let them rant about their day.

Tails hadn't wanted to admit it, and actively pushed it away but this feeling kept returning to him, one too familiar for him to deny much longer.

He liked (Y/N), didn't he?? The feeling was definitely similar to the ones he felt for Sonic, yet they weren't as well. They could both rival his deadly obsession with the blue blue yet also surpass it.

Before anyone knew it, Green Hill had two people that Tails was always hovering over.

Tails started making more and more trips out of his lab, skipping out on projects or time he usually spent twisting and toying with Any's emotions for Sonic in favor of just always being around (Y/N).

He 𝘩𝘢𝘥 to know what (Y/N) was doing 24/7. That's why he always kept tabs on them. If they went anywhere, if they left their house, if they were eating at lunch, if they did anything else, anything to indicate that they weren't alone in their home at all times, Tails would immediately know.

So, when one day you had gotten more dressed up than usual and made your way to Angel Island to meet up with a certain red echidna, he was the first to know and He. Was. 𝘗𝘪𝘴𝘴𝘦𝘥.

For the first time ever since he got there, he refused to hang out with Sonic. He stopped hovering around the blue blur, instead almost immediately making a B-line for Angel Island. He offered little to no explanation for the hedgehog, though Sonic was grateful nonetheless for finally being able to be left alone.

Once catching the familiar glimpse of (H/C) and Red, the fox was quick to duck behind some of the islands nature, using that as a way to obscure his figure as he took in the scene in front of him.

(Y/N) was sat comfortably on the ground, legs crossed and leaning against the stand where both Knuckles and the master emerald were perched upon.

The two were talking about nothing and everything, (Y/N) chatted away meanwhile Knuckles watched the morbian, paying attention to every single word as if they were speaking of the world's secrets.

Knuckles and (Y/N)'s conversation was audible to the fox, though all the two titled fiend could really hear was white noise. Disgust and bile built in the back of his throat at the sight. His disgust soon bubbled into pure unadulterated rage when he saw the red echidna reach over to the morbian and grab for their hand, holding it as if it were the most casual thing in the world. Who did he think he was to even touch (Y/N) so casually?? He was a nobody. You could replace this Knuckles with any other from any other universe and no one would be able to tell the difference.

He was nothing compared to Sonic--Compared to (Y/N).

Before the canine even really registered it, he had sprung out from his hiding spot, almost leaping onto the echidna in an attempt to wrestle the morbian away from (Y/N). It was a foolish thing to act off of his emotions, cause even with the adrenaline coursing through his veins he was still lanky and held absolutely nothing against Knuckles in combat.

In an instant, he had been pinned down, the red echidna holding down both wrists above his head.

"What the fuck are you doing?! What the hell, Tails?!" The echidna exclaimed, his rage possibling rivaling Tails'.

(Y/N) jumped back, their face contorting at the sight before them. They stayed deathly still, unsure if they should do anything in the moment as Knuckles seemed to have it under control.

"Get off of me, you filthy vermin!!" Tails hands futily reached up, clawing at the air near Knuckles face, but never managing to get close enough. "I'll claw your eyes out, imposter!!"

"Tails!!" The fox cringed at the sound of (Y/N)'s voices he almost forgot they were there in his rage. "What the hell has gotten into you??"

"This imbecile thinks it's alright to touch YOU like that! To be with YOU like THAT!?!" Tails yelled, not caring about how loud he sounded. Knuckles seemed to get angry at this, his grip on Tails tightening as his teeth grinded together. "He's an imposter, A fake!! He's not even good enough to matter!! He's no one in a million!! He's no Sonic!! He's not your best friend!" Tails writhed and swatted at Knuckles, attempting to somehow get the echidna off of him.

He was lucky enough to get a good kick to the groin, making Knuckles stumble back with a pained hiss. He looked ready to fight Tails, but a the yellow furred fox was quicker to action, grabbing for the closest thing near him which just so happened to be a rock.

Tails pounced back onto Knuckles, lifting the rock high before striking it down against his skull.

"Imposter!!"

Again.

"Cretin!!"

And again.

"Friend thief!!"

Hands wrapped around his neck, using it to yank him away from Knuckles before he could strike again, though the effects were already done.

Gurgling noises escaped what remained of Knuckles skull before his body went limp, the remaining fight that it contained draining away along with his life.

"Tails...What the fuck did you do?! Do you know what you had just done??" (Y/N)'s voice cracked, so much emotion being continued behind their words. They had just watched their friends life drained before their eyes. Not only that, but it was by the person they trusted, the one they thought were their hero, their friend.

"He was replaceable!! They all are! I can get you a new one in the snap of an eye--One that knows to keep its FILTHY hands away!!" This wasn't the voice they recognized. This wasn't the one that belonged to their Tails. The love and care that was once held in his tone was now filled with hate and lunacy.

"You....You're a fucking freak!!" (Y/N) cried out, their hands that were once grabbing onto the Fox's neck and shoulders now pushing him back, letting him collide on the harsh concrete of the Master Emeralds stand.

(Y/N) didn't know what was goingon in their brain, they almost blacked out from the rage but they do recall their body moving on their own. They kicked and stomped at the two tailed fox, making sure he'd stay down.

Tails didn't fight back. Unlike with Knuckles, he actually seemed to revel in this pain. A sickening, deafening cackle left his body, almost involuntarily. Every kick and stomp only seemed to fuel this giggle fit of his. He was clearly enjoying himself, watching with a wide smile as his eyes stayed locked into (Y/N)'s.

(Y/N) wanted to stomp his head in, to massacre his body like he did Knuckles, but they couldn't. They weren't as heartless as this Tails and they certainly weren't as vicious.

A whimper involuntarily escaped their lips as tears started to prick in the eyes. They felt betrayed, they were used. Their leg froze mid air, just hovering over Tails though they couldn't slam it back down on his form even if they wanted to. They wanted to go back to a couple minutes ago, where they were just having fun with a friend, when Tails wasn't even there.

Cracking noises came from the joint sofa Tails as he contorted his body, forcing his sore limbs to lift himself up.

With the pop of his joints he seemed to be...longer, lankier. More and more, he strayed from what (Y/N) knew tails to be until he was practically unrecognizable. He wasn't Tails, he was his own creature far far from the loveable tech-whiz (Y/N) knew.

"Oh, my dear. Don't tell me you're actually crying over a vermin of their caliber??"

Crazed eyes looked up at (Y/N) with an adoration of some kind, one that the morbian recognized as the lions he'd give his blue friend. "You have me, and I'm certainly better." His hand reached up and grabbed for (Y/N)'s leg, setting it down before his arms wrapped around it, hugging it close to him as if he were worshipping (Y/N)'s physical form. Hypocritical. This was far worse than holding hands and yet where was his punishment?? "I've always been there, since the beginning. I'm Tails, Sonic's best friend, the player two. You're hero."

(Y/N) shook their head violently, trying to free their legs from Tails' grasp only to be met with his two tails wrapping against it, keeping it in place. "Stop. Stop trying to leave. I'm the best for you, I'm your friend."

"I love you."
