A/N: Thank you for your request! I spent a long time researching each species, checking how they typically mark each other by scent in nature. I didn't have as much success with hedgehogs, but learning a bit more about foxes, echidnas, and jackals was quite interesting. I hope you enjoy it!
Sonic
You were sprawled on the living room sofa, focused on watching a TV series and enjoying your afternoon.
That was when, with a blue blur faster than your eyes could follow, the hedgehog stopped leaning against the doorway.
You glanced at him for a second, then returned your attention to the screen while Sonic stayed there, arms crossed, green eyes studying every detail of you.
Slowly, a mischievous little smile stretched across his muzzle. Usually, that smile meant trouble, but for the moment, you decided to ignore it and wait to see what he intended to do.
With determined steps, the hedgehog pushed off the doorframe, walking toward you and hopping onto the sofa beside you.
But to your surprise, not even half a minute later, he was hovering over you, that same grin still in place.
“Sonic... what...” Your sentence never finished, because to your total shock, he suddenly shoved his muzzle against your neck without warning, taking a long sniff that sent shivers through your entire body.
He wrapped his arms around you, trying to impossibly bury his face even deeper into you. And to surprise you even more, he started rubbing his neck against you, practically shoving a mouthful of fur in your face.
“Hey... feeling needy today, huh?” You laughed softly, wrapping your arms around him.
“Yeah... I just like being like this...” he murmured, pausing for a second before continuing to nuzzle his muzzle against your throat, his cold, wet nose tickling you with every little touch.
“You’re really clingy today, love...” you commented, watching the way he slowly, almost unconsciously, hooked his claws into you too, anchoring himself to you.
After sniffing your scent one last time, he rubbed his cheek against yours, brushing soft quills over you. One of them grazed your nose lightly, making it itch, and your hand immediately moved to cover your nostril so you wouldn’t sneeze.
Letting out a satisfied sigh, Sonic pulled away from you, flashing the same sly smirk, his tongue briefly swiping over his upper lip while his green eyes admired you.
You giggled, noticing how his fur had gotten all tousled after so many minutes of rubbing against you.
“Happy now?” you asked, settling back on the sofa so you could get back to your show.
“To be honest... yeah, a lot...” he chuckled, standing up from the sofa with slow movements and stretching. “If I... happen to do that again, don’t be surprised...” he added, winking at you, leaving you confused.
Walking toward the exit, Sonic left you alone again, thoughtful about what had just happened.
Was it really an act of affection and neediness... or was there something more behind it?
Shrugging, you pushed it aside for now, even though you wondered all week why Mobians within three kilometers suddenly refused to even look in your direction. It raised plenty of suspicions, but in the end, you weren’t familiar enough with their species’ habits to reach any concrete conclusion.
And deep down, Sonic felt an almost impossible-to-hide sense of masculine pride while walking by your side. He knew very well that you were more than marked with his scent to anyone with a sharp nose.
Shadow
Night had just fallen. You were focused on a small pocket book, sitting on the bed while waiting for Shadow to return from a long day doing G.U.N. missions, as he always did on his freer days.
Hearing the front door open, followed by heavy footsteps, it didn’t take long for the black hedgehog to appear at the bedroom entrance.
He had a hand on his neck, rubbing the back of his quills as he approached you with slow, controlled steps. He let out a low huff, analyzing your form.
You looked up from your book at him, opening a wide smile.
“Hey, love... was your day alright?” you asked.
He shrugged, closing his eyes and crossing his arms.
“It was tiring and heavy... but I suppose productive enough...” he commented, taking a deep breath.
Slowly, he looked at you with his red pupils and then moved forward, climbing onto the bed and settling at your side.
To your surprise and shock, Shadow slowly placed a firm hand on your waist as he lay down next to you.
“I was gone too long... I need this...” he offered as a vague explanation, but it was enough to make you relax a bit.
What impressed you even more was how he brought his face close to yours, resting his chin against your cheek, taking a deep breath and gently brushing it from side to side.
You froze, glancing sideways at the hedgehog beside you. Your first thought was that maybe he hit his head at some point during the mission and that’s why he was acting like this, this wasn’t typical Shadow behavior.
However, you soon adjusted to the feeling of him rubbing against you, alternating between burying his muzzle against your neck and inhaling your scent until his lungs were full, then letting out a small, nearly inaudible growl before resuming the affectionate rubbing against your face.
“Shadow, my love... you look really cute doing that...” you laughed quietly, closing your book and tossing it aside, fully focused on the soft affection he was giving you now.
After some time, the hedgehog slowly pulled away, his chest rising and falling with heavy breaths as he looked at you, letting out a satisfied huff.
“This is better...” he muttered hoarsely, lying down on his side of the bed and resting his hands behind his head.
You blinked once, then twice, focusing on him for a few seconds as he closed his eyes, drifting into a quick nap and leaving you confused by those last words.
But for now, you decided to let it go and let him enjoy a much-deserved rest.
--*--
The next day, during a quiet and pleasant afternoon, you were doing your nails with Rouge at home.
After chatting about several topics, you mentioned how Shadow had arrived the previous night, been unusually affectionate, and then fallen asleep.
To your surprise, Rouge froze completely, a sly grin spreading across her face.
“He got all affectionate, huh? Like... rubbing against you and sniffing you?” she asked, raising a brow with a sideways smile.
“Well... yes, how do you know?” you asked, surprised.
“Sweetie... your dear boyfriend was just marking his territory on you... Leaving his scent all over you... basically telling every other guy out there that you belong only to him.” She giggled. “Mobian and hedgehog thing... I thought you knew...”
Your jaw dropped and your eyes went wide. Everything made sense now, his behavior was completely explained. He had come home possessive after his day and decided he was going to mark you so everyone would think twice before approaching you.
At that exact moment, the hedgehog walked into the living room, a little bowl in hand, munching on coffee beans.
You focused your eyes on him, making an indignant expression.
“Shadow. The. Hedgehog...” you called out, making him instantly freeze mid-step, staring at you attentively. “I found out everything... So you were marking me as your property, huh?” You crossed your arms, though your expression was more playful than angry.
He swallowed, glancing between you and Rouge, then cleared his throat and spoke in a low, rough voice.
“It was necessary... you are fragile... it helps keep danger away...” he explained, though it was painfully obvious it was just a flimsy excuse, making you burst into laughter.
“Seriously... I can’t believe it... how possessive...” you laughed, shaking your head in disbelief.
Rouge laughed along with you, winking at Shadow, who shot her a sharp glare, not at all happy that she had exposed his secret.
But despite everything, deep down, you felt oddly proud of it, you liked it. To you, it felt almost like wearing a promise ring, and nothing made you happier than being recognized as the black hedgehog’s romantic partner.
Silver
The kettle in front of you boiled on the stove as you stood waiting for your tea to finish, planning to share some with your boyfriend.
Suddenly, to your surprise, you felt a pair of familiar, timid arms wrap around your torso from behind. Subtly glancing back, you saw Silver, suspended by his psychokinesis, eyes closed, muzzle pressed into your back.
“Hey, love...” you said, wrapping an arm around him too.
“I... missed you today... Can I stay like this for a bit?” he asked, voice muffled against your clothes.
Laughing softly at how adorable he looked, you ran your fingers through his quills.
“Of course, sweetheart, stay as long as you want...” you murmured, watching him sigh contentedly.
Silver used his powers to float slightly higher, hugging your neck now, burying his face in your hair and sniffing your scent over and over, then releasing the air with something that sounded suspiciously like a small moan of satisfaction, which you decided not to comment on. He must really have missed you.
But slowly, instead of just sniffing you, the hedgehog began rubbing the side of his face and forehead against your neck and nape, brushing his fur and quills against your skin, making you giggle from the ticklish sensation.
Smiling brightly, you looked at him.
“I can tell you really missed me... you’re being so adorable with me...” you said, gently stroking his back while turning off the stove and picking up the kettle to pour the tea.
He let out a small grunt in acknowledgment, slowly pulling away and using his levitation to return to the floor.
But you noticed he had a deep blush beneath his fur, looking away and fidgeting with his fingers, a mix of nerves and shyness that left you puzzled.
“The tea is ready, do you want some?” Silver nodded quickly, walking to the table to sit and enjoy the relaxing drink with you.
Even though he was extremely embarrassed about what he had done, the hedgehog’s instincts had spoken louder than reason. And now he couldn’t calm his mind no matter how much he tried.
“H-hey...” he called.
“Yes?”
“Would you mind if I did that again someday?” he asked, looking away.
“What? Those cute hugs? You can do that whenever you want, I don’t mind.” you replied, completely unaware of the real reason behind his affection.
Silver smiled wide, his eyes sparkling with excitement as he grabbed the teacup to drink.
Even though he wasn’t used to marking a partner like that, he had to admit to himself, it was incredibly thrilling. And he felt a huge sense of pride knowing his scent was on you, showing everyone you were already taken.
Even if he was also unaware that you didn’t understand that custom. In the end, Silver was just happy you had agreed to let him mark you again in the future.
Scourge
The door to your room opened with a small creak, revealing the green hedgehog. His quills and fur were messy, and he had a towel over his shoulder, probably having just gotten out of the shower.
You were lying on the bed, wondering if you wanted to get up so early or wait a little longer.
With slow steps, Scourge approached the bed, climbing up with you, soon flashing a mischievous grin, tossing the towel aside on the headboard.
The hedgehog snuggled against your body, letting out a rough chuckle and giving you a sly little smirk.
Scourge didn’t even pretend to be subtle about what he was doing. He pressed his muzzle against your neck, sniffing hard, releasing a sound that was somewhere between a growl and a moan.
“Scourge… what are you doing, love?” you questioned, but he only gave a low grunt, not responding directly, continuing to rub his face against yours. You could smell his fur, that mix of your boyfriend’s natural musk with the pleasant scent of his bath.
He stayed with his muzzle against your skin for so long that when he pulled back, he was a bit breathless, but quickly dove in again, this time slowly running his tongue along your skin, sending a shiver through your whole body.
“Mine only, babe…” he murmured hoarsely, growling again as he now rubbed his quills along your collarbone. “You’re mine only, got it?”
You let out a quiet laugh at his strange behavior.
“I know I am… I’m your girlfriend… I’m not going anywhere.” Wrapping your arms around him, you pulled him even closer, kissing his cheek, and he immediately gave you a quick peck on the lips in return.
He inhaled your scent again, now letting out a content and satisfied sigh, allowing himself to lie beside you, gripping your waist and keeping you pulled against him as he closed his eyes, enjoying the early morning with you.
Little did you know that this wasn’t just a moment of clinginess or something like that. And it was unlikely you’d notice what had really changed in that moment.
Meanwhile, Scourge would probably walk around with his chest puffed out everywhere, extremely proud of having his scent all over you, warning any other man that you already belonged to him.
Tails
The two of you were lying on the couch watching a chill comedy movie. Tails seemed pretty relaxed, resting on top of you, his twin tails slowly swaying from side to side, showing just how calm he was.
At some point, he stretched completely, yawning and scooting up until his cheek rested lazily against yours.
“Hmm, this is comfy…” he commented.
“It really is… so warm it’s making me sleepy…” Your hand rested on his back as you adjusted yourself on the couch.
Suddenly, the fox’s nose caught a sweet scent. Tails inhaled deeply and exhaled in satisfaction. He had picked up your natural smell, the same one that nearly made him melt every time he was close.
Then something inside him, an instinct of sorts, suddenly took over.
Swallowing hard, his eyes shifted between you and the TV, wondering if it was really a good idea to do what he was thinking.
But no matter how much he tried, he couldn’t stop himself. With a low little growl, he leaned forward until he reached your neck with his muzzle, rubbing the fur of his chin against you and sniffing afterward.
The sensation tickled a bit, making you laugh softly.
“Tails… you’re being really cute…” you sighed, hugging him even tighter while he continued rubbing his chin along your soft skin.
His tails, almost unconsciously, wrapped around your waist, ensuring his scent spread around that area too.
“You smell so nice…” he murmured proudly, squeezing his eyes shut.
Leaning forward, you gave a tiny kiss to the top of his head, making him open a wide smile.
Sighing with satisfaction, he pulled his muzzle slightly away from your neck, though he still kept his tails wrapped firmly around your waist.
“H-hey… do you think… we could do this more often…” he asked, suddenly feeling way too shy.
“What? Movie sessions?”
“Everything…” he whispered.
“Of course, my love… whenever you want…” You smiled sweetly at him, cupping Tails’s cheek gently before hugging him again and turning your attention back to the movie.
For the fox, this need to spread his scent over you was new, but he couldn’t get the idea out of his head that he needed to do it more often, to make everyone understand you were his.
And for some reason, smelling his own scent on your skin gave him this strange sense of achievement, making his fur bristle slightly while he enjoyed your closeness endlessly.
Even though he wasn’t the type to puff out his chest with pride for having you ‘marked,’ he would definitely be ten times more excited to go out with you in places full of Mobians, just so they’d know you were Tails’s beloved girlfriend.
Knuckles
Admiring the clear afternoon sky, listening to the distant songs of birds, you were lying on the grass of one of Angel Island’s fields, spending some time with your boyfriend.
He was beside you, the echidna’s hands resting behind his head as he also breathed in the pure nature around you, enjoying such an intimate moment together.
Slowly, Knuckles turned, scooting closer and wrapping an arm around your torso, pulling you nearer.
With a low grunt and without saying anything, your boyfriend suddenly buried his muzzle against your throat, placing a tiny kiss that sent a soft shiver through your body. You giggled, running your fingers through his soft quills.
“What are you doing, love?” Despite your question, Knuckles stayed silent, sniffing a few times, and to your surprise, lowered his face to your collarbone, rubbing the top of his head against your cheek.
It was then that you also noticed the natural musk scent coming from him, probably stronger because he was an echidna. You were already used to it, not even imagining there might be a completely different meaning behind that affectionate gesture.
“You’re being really clingy today…” you laughed softly, and Knuckles opened a wide grin, showing his fangs.
“Hmhmm…” he nodded, finally pulling back, looking satisfied. “I like being close to you like this…” he admitted, placing a large hand on your cheek with a rough chuckle.
“I like it too… especially when you’re this sweet.” You placed your hand over his.
“Let’s do this more often then…” he suggested. You nodded without even thinking, smiling gently.
Even though it seemed totally innocent, to the guardian, it was more like an important ritual. And he felt a huge sense of masculine pride in sensing his echidna musk on your fragile human skin.
Knuckles was definitely more than willing to keep you marked as his partner, and his only.
Infinite
The night was a bit cold, filled with the sounds of the city’s traffic below. Settling on the couch under your blankets, you were busy sipping a mug of hot chocolate, enjoying the sweet taste.
Light footsteps echoed through the house, and soon the jackal appeared in the hallway. His heterochromatic eyes examined you from afar, analyzing your curled-up figure seeking warmth.
His ears tilted sideways as Infinite slowly approached, slipping under the blankets beside you.
“You feel that cold?” he asked, crossing his arms.
“I don’t have fur to keep me warm, you know? Cold destroys me…” you muttered, taking the last sip and placing the mug on the coffee table.
Infinite let out a low hmph before moving closer, gently guiding you to lie down on the couch, following you and settling by your side.
His long tail swayed a little, positioning itself over your feet.
Grunting and letting out a low whimper, the jackal rested his head at the curve of your neck, his claws lightly pressing on your ribs.
Slowly, he gave a few quick sniffs, furrowing his brow and showing his fangs. It didn’t take long before he got even closer, burying his muzzle against your throat, giving long licks that made you squirm.
“H-hey…” you laughed, shifting a bit. “Love… that tickles…” You reached to stop him, but Infinite was quicker, grabbing your wrist and preventing you from interfering while he continued licking your skin.
Your eyes shut tight from the sensation. But you opened them again immediately when you felt his fangs nibbling on your sensitive skin.
“Infinite… what are you doing?” you asked.
“Just stay still…” he growled, continuing his little bites all around the area, moving up to your jaw and then down to your collarbone.
Pausing for a second, the jackal inhaled deeply, growling, then pressed even more of his body against yours, rubbing himself against you completely, making you laugh again.
“You’re really needy today, huh? I’ve never seen you ask for attention like this…”
Even though you were talking, the jackal wasn’t paying attention to your words at all, he was way too focused on his task, his fur shedding a bit and sticking to your clothes while he continued those strange touches.
Suddenly, he stopped, lifting his face. His ears twitched as he sniffed again, then he gave a dark smile.
“Much better… now you really look like my partner…” he chuckled roughly.
“What do you mean?” you asked with confusion.
“Everyone will know you belong to me…” he grinned, showing all his sharp teeth, his tail swaying casually.
And then it clicked, he wasn’t just being affectionate. He had marked you in every possible external way.
Touching your neck, you were sure there was a big mark where he had been biting, and his canine scent must have been overwhelming for anyone with a sensitive nose.
“Infinite!” you exclaimed, but he placed his index finger right in front of your lips to silence you.
“Shhh… don’t tell me you don’t like having my scent on you… letting everyone know you’re mine…” he murmured softly, pressing his forehead to yours.
“Well… that’s not the point… you could’ve warned me first! Now I have to cover this up with foundation…” you pointed at your neck.
“Let them see… it’s my symbol… a sign that you belong only to me…” the jackal laughed, settling beside you. “Now move over, I’m gonna warm you through the night with my fur…” Opening his arms, he waited for you to curl up against him.
Sighing, you rubbed your temple but eventually obeyed, snuggling against your boyfriend, accepting that you’d have to live a few weeks with that mark until it faded, or until he decided to make another, which, let’s be real, he absolutely would.
Despite the embarrassment, there was a small sense of satisfaction inside you, a feeling of belonging, carrying something so symbolic.
And as he held you, warming you up and helping you fall asleep, you felt certain that maybe you could get used to showing the world who your partner was.
Mephiles
While you were busy watering your plants, the afternoon sun was slowly setting on the horizon, with spring’s soft breeze washing over you. For a moment, you stopped to inhale the sweet air of nature, deciding to take a break.
Walking through your garden, you sat under the shade of a tree, resting while appreciating the day.
Suddenly, you sensed a very familiar presence near you.
Quickly turning your head, you looked around but saw nothing, only your shadow, unmoving.
“Meph… I know you’re there, you can come out…”
At your words, the darkness finally took shape, materializing.
“I’m impressed you can already tell where I am…” he commented, sitting beside you, resting his muzzle against your shoulder.
“Experience… I’m getting used to these things…” you explained, leaning your head lightly against his.
“Hmm…” he grumbled.
But then, for some reason, he began to feel a strange sensation he couldn’t identify. Mephiles wasn’t sure if it came from the species he had chosen for his physical form or if it was something inherent to himself that was only now surfacing.
Tentatively, he leaned closer, reaching your nape, sniffing and catching your sweet natural scent, which made him growl softly as his claws grazed your waist.
“What are you doing, sweetheart…”
“Testing something…” His vague answer only confused you more, but you let it go for the moment, allowing him to nestle against your neck as he began slowly rubbing his face from side to side, alternating between his cheek and chin.
Feeling his soft fur tickling you, you let out a little laugh.
“Your reaction is… the most pleasing possible…” he murmured roughly, still rubbing his face against you. “I really appreciate these little sounds of contentment you make…” he added, clutching you a bit tighter and sniffing your hair.
He seemed extremely determined in what he was doing, though his behavior was anything but innocent.
“Meph… wait a second.” You held his shoulders. “Why are you doing this?” you raised your eyebrow at him.
“Well… isn’t it obvious… I intend to mark you as mine…” he murmured darkly, letting out a muffled chuckle. “And only mine…”
You laughed when you heard him vocalize his intentions.
“No need for that, sweetheart… I’m not planning on leaving you…” you assured, placing your hand on his cheek.
“Oh… I’m not worried about that… I just want to scare off anyone who might think they can have you…” he growled, raking his claws lightly down your side, making you shiver.
Satisfied, he grunted, pulling away from you, examining you and inhaling deeply, laughing with proud satisfaction.
“Perfect… now no one will try to steal you from me…”
“Just a little possessive, aren’t you?” you teased.
“You have no idea, my dear…”
Stretching, he lay across your lap, closing his eyes and resting his hands on his belly in a calm, peaceful gesture. He didn't look at all like the deadly dark creature he was when he behaved like that around you.
And even though he was extremely jealous when it came to you, you admitted you enjoyed his attention, and the way he liked everyone to know you were very much taken, even if your relationship wasn’t exactly the most conventional in the world
