*RIIINNNNGGGGGGGGG*

The alarm clock next to your bed blares out with a shrill noise, interrupting your deep slumber from your cozy and warm bed. The morning sun pokes through a small crack in your blinds and dimly illuminates your bedroom, the excess light helping your brain wake. You instinctively mumble out a small protest as your groggy mind slowly wakes itself up from the annoying ringing. With a tired groan, you blindly hit your bedside table to locate and press the snooze button before settling back in. The alarm now snoozed, your heavy eyelids open up and adjust to the brightness in your bedroom, before a small smile comes across your face.
Normally, you hated waking up in the mornings, abruptly torn away from your cozy bliss dreams to face a busy day of work. You could just sleep forever if you had the choice. But today wasn't any ordinary morning. It's your special day, your birthday, a day all about you and you only. A smile stretches across your face at what the day had in store. It's going to be wonderful; you could already tell. Heck, it feels like a day where you could win a million dollars or go to space.
Your phone vibrates next to you on the bed, and you quickly reach for it, seeing a message from one of your friends.

Tails: Hey birthday buddy, it's Tails! Just wanna say... Happy birthday!! :) :) :)

The message is followed by several happy face emoticons, an emotion that is fitting of his adorable and enthusiastic personality. You tap your phone a few times.

You: thanks :)

Even if he's a celebrity hero in his own right alongside Sonic, you managed to keep a close friendship with Tails after meeting him at the Mirage Express on the first day on the job. You both bonded over being detective partners during a murder mystery party that went out of hand when it was revealed that Dr Eggman had orchestrated another one of his evil plans. The two of you became close ever since, texting each other regularly and even hanging out twice in the short timespan after. Not surprisingly, it was difficult to schedule a time together, especially with all the hero work that came with his job, but you always appreciated his friendship, and always had a great time when you did get to spend time together.
Your phone vibrates again, as a second text appears on your screen.

Tails: Hope you didn't forget about our special birthday gift :) We think you're really gonna like it!

We? Was someone else tagging along? Your thumbs quickly tap out a response.

You: ??? who else is coming?

Your eyes watch the ellipses animation appear on your screen, and then disappear, reappearing once more and then disappearing again in a cycle. Tails was probably thinking out his answer. After a few seconds, the ellipses finally vanish and are replaced by a text.

Tails: oh don't worry it's just Amy. Just meet me at the Station Square train station in an hour! I'll be waiting! See ya soon
Tails: :)

Amy? Ohh, it took a moment for that name to register but you know her as well. Sort of anyway. Another one of Sonic's friends, she was the birthday girl from the Mirage Express murder-mystery party. From what you remember, she's a spunky, energetic girl who's very fond of Sonic. It's bewildering to think that those two aren't a couple despite their closeness. Although, it perplexed you on why she would come along with Tails? Maybe she had a present of her own to give you. You doubt it though; you hadn't really interacted with her outside of that one day. She probably just wanted to tag-along or something. You didn't mind at all, you actually looked forward to it.

You: ok. thanks again, see ya later :)

You set your phone back on the table and stretch your arms out, a small yawn escaping from your lips. You needed to get yourself ready for the day, and you didn't want to be late on your birthday. After having a quick breakfast and getting dressed for the occasion, you head towards the front door eager to meet up with Tails.
As expected, the journey to the train station didn't take long. There weren't many people on the platform, as only a couple of individuals stood by the rails. It was quiet, which you were grateful for. You weren't much of a social person like Sonic, and crowds of people made you uncomfortable. From a distance, you could see both Tails and Amy waiting for you, both sporting a detective and journalist outfit; the same ones when you first met them.
"Hey, birthday buddy!"
The excited shout is followed by a sudden hug from Tails, his strong arms pulling you in and squeezing tightly. You can't help but smile, and you hug him back.
"Hi, Tails," you say, blushing. You see Tails hand you a wrapped box with a ribbon tied to it, and you quickly take it.
"I hope you like it," Tails says with a grin. "It took a lot of digging around from Amy, but we got you the perfect gift. Trust us on this, buddy!"
You turn your head to the side to see Amy giving you a wide smile and a mischievous wink, and you look down at the gift. Of course... she's piggybacking from Tails gift but you don't say anything. It's small but light, and you're unable to figure out what's inside.
"Don't open it yet," Amy says ominously. "Save it for when we get on our train."
You look up, confused, but before you could question what Amy meant, the train suddenly pulls up to the platform. It looked majestic, striking a similar design to the Mirage Express but with a different colour scheme. You see the yellow fox pull out three tickets and hand them to the ticket person before following him and Amy onto the train. As the doors slide shut behind you, you glance back at the empty platform for only a moment before Tails grabs your attention again.
"Okay guys, I've got us a private compartment so we don't get interrupted," Tails explains as he leads the two of you further into the train. "Follow me."
He guides you and Amy down the corridors. The inside of the train is surprisingly luxurious, the seats soft and the tables well-kept, much like a high-class hotel. In a way, it reminded you of the short-lived time where you worked on the Mirage Express, although now that you're off duty, you had a feeling this ride will be a bit more worry free.
After a walk through the carriages, Tails stops at one of the doors, and slides it open to reveal a small, cozy compartment, with a couple of seats and a small table etched on the wall. You and Amy follow him inside, and as the door shuts behind you, the three of you sit down with Amy and Tails sitting directly opposite you.
"So..." You say, holding the box up. "Is now a good time to open this?"
Amy grins and nods, and Tails gestures towards the present, and you can't help but notice the nervous excitement in his eyes. You're curious yourself, as your hands fiddle with the ribbon. Tails and Amy are obviously hiding something, and you're eager to find out what it is. You can't help but notice that their eyes are fixed on you, as they stare in anticipation, eagerly waiting for you to open their present.
After a brief struggle with the wrapping, the box opens to reveal its contents. Your eyes widen however when you see what's inside.
"W-What?!" you exclaim, "T-These are..."
Inside the box are a couple of dirty socks, and the stench hits you hard.
"Oh... my god..." you whisper.
You look up from the box and stare at Amy and Tails, both having smug expressions on their faces, their eyes locked onto yours. It was clear that they planned this all along. The question was, why?
The yellow fox was the first to speak, timidness in his voice, "So, I've been noticing that every time we hung out, you've been staring at my shoes a lot. At first I thought it was because you were still nervous around me."
Amy then added, "Then, after talking to me about it, I suggested that maybe you might have a foot fetish."
Tails nods, and continues, "So I held an experiment. Do you remember that time where I went to your house to play video games? When I 'went' to the toilet?"
Uh oh. You know where this is going. Poop, did you really get caught in the act without realising it?
"Yeah... you weren't exactly subtle about it" Tails says, albeit slightly embarrassed for you, "I tip-toed quietly, and I saw you sniffing my shoes."
You're growing more and more embarrassed by the minute, as your face heats up, your cheeks flushed red with embarrassment. The fact that he pretended not to know about this makes this even more mortifying, but now that the cat's out of the bag, there's no hiding it now.
Tails gives you an embarrassed smile and continues. "A-Anyway, we thought we might-"
"We gave you dirty socks for your birthday!" Amy bluntly interjects, her voice bubbling with enthusiasm, probably with too much optimism.
The pink hedgehog looks back towards Tails, and he exchanges a knowing glance back at her, seemingly reading her mind. You stammer, unable to form the words to reply back to your two friends. Your face grows hotter and you avert your gaze away from them, as they chuckle.
"Don't be so shy! It's your birthday after all, it's not like we're gonna make fun of you," Tails reassures, "Um, well maybe tease ya a little."
"Yeah!" Amy chimes in, "These socks are just for you! It took some convincing from a few of our friends but we got them to give them to you!"
You glance back at the box, and stare at the dirty used socks inside. It seems like this gift was prepared well before today, with a few different pairs of socks, each having their unique smell to them that made you want to bury your face into them with each passing seconds.
"There's Sonics, of course," Tails explains, his voice bringing you back to reality. He points at at all the other socks, describing who's was who's, "But we've got some from Blaze, Vector, Espio, Knuckles, Rouge, and even Shadow! We've even thrown in a couple from us."
Wait do they know also?
"Don't worry, we didn't tell them it was for you specifically," Amy reassures. You genuinely can't tell if she read your mind that time. "Your secret is safe with us! Besides, this just means we can keep you all for ourselves."
She winks at Tails, and you chuckle nervously at what she's implying.
"You can enjoy those socks later," Tails says, a smirk forming on his face, "For now, how about we do something a little more hands-on."
"H-hands on?" you stutter with a jittery tone.
"Yeah, it's about time we kick off the main event, right Tails?" Amy continued.
"Yes, pardon the pun," the fox replied, his voice low and seductive. He smirks with a mischievous glint in his eyes. You gulp, knowing full well what they mean. Your eyes widen as Tails suddenly raises his legs up towards you, resting his shoed feet on your lap. Your face flushes a deep shade of red, anxious to take this opportunity. Your eyes dart around in an attempt to find a way out, but you knew deep down that you weren't getting away that easily. You're exposed, and the two-tailed fox has you marked down as his prey.
"Take off my shoes," Tails orders teasingly, "And give my feet a sniff."
You're frozen, unable to move. The raw unfiltered scent of his feet is only blocked by his dingy red and white sneakers, and the anticipation is driving you wild. Amy is sitting there, staring at you eagerly with an expectant expression on her face. Tails wiggles his toes in front of your face (not like you can see them in the first place), the rubber squeaking slightly.
"You heard him," Amy affirms, "Do it."
Your heart thumps in your chest, your face feeling hot and flustered as your hand reaches over to Tails' feet and pulls his shoes off. As the smell wafts through the compartment, a shiver of excitement goes through your spine as you're greeted by the sight of the yellow fox's socked feet. It's dirty, but in a good way, as you take a second to marvel at them. He wiggles his socked toes at you, as if beckoning you to take them off. Your face burns and you're pretty sure the blush is visible on your cheeks as the thought of smelling them passes through your mind.
"Whatcha waitin' for?" Tails teases, a playful demeanour in his tone. "I know you've been wanting to do this for a while, so why not start off on the right foot?"
Despite how bizarre this situation is for you, Tails still manages to make you laugh, albeit nervously, at his attempt at a pun. You mutter, "H-haha y-yes, sor-or-ry."
You lean forward and raise his foot to your nose taking a deep breath, letting the musky boyish scent of his foot invade your nostrils. A little moan escapes your mouth as the two-tailed fox starts rubbing his socked foot against your face, taking control. His foot is sweaty and warm as you continue to inhale the smell. You can feel him press his socked sole against your nose as he pushes it down against you. It's degrading, you know it is but damn, it feels good. All the while, Tails and Amy couldn't help but giggle at your predicament.
Tails attempts to stifle his laughter, "How's the smell?"
You manage a quiet moan, your voice muffled through the dirty fabric, "P-pe-perfect..."
The yellow fox smirks, and switches his foot with the other one, rubbing it against your face, forcing you back in to breath the stench of his feet. Predictably, you stay there, obediently taking it. The fox continues to play around with your face, using his feet to tease you, as you breathe in his stinky musk, letting it permeate throughout your senses. Heaven. A few more minutes pass before Tails puts his feet down away from you, leaving you in a panting state. You try to regain your composure but then Amy lifts her feet and places them in your lap, still encased in their shoe prisons.
"My turn!" Amy squeals, excitement in her voice, "Now, be a good birthday boy and take off my shoes."
You gulp, knowing what to do next. The pink hedgehog's red shoes are well kept and pristine, and you take care not to scuff them up as you grip the heel of her right shoe and gently pull it off. You delicately place it on the seat next to you, revealing a cute pink sock with red at the tips of her toes. You remove her left shoe as well, revealing and doing the same. 
"Oooohhh!" she gasps in glee as she stretches her legs out, "I've been walking all day and my feet are so tired!"
Tails deadpan stares, "Uh Amy, you weren't walking at all today, remember? You rode to the station in a taxi."
Amy looks down sheepishly and giggles, "I was trying to make a dramatic scene here."
You let out a soft laugh, amused by her behaviour, before turning your attention back towards her socked feet. You reach for her right foot and give it a sniff. The scent is less powerful than Tails' feet, between the lines of pleasant and musky but it's one that's welcome.
However, Amy wasn't going to let you smell for long.
She giggles and playfully slaps your face away from her foot. "Uh uh, I want you to massage them before you start smelling."
You pout, pretty much involuntarily.
"It's his birthday, Amy," Tails argues, "If he wants to smell them, then let him."
"It's f-fine," you interject, not wanting to get caught up in an argument over something as simple as this, "I don't mind."
"Good boy," Amy praises as she wiggles her socked toes at you. "Now, let me feel those fingers of those." 
You do as she says, and start massaging her right foot first, squeezing her toes and pressing into her sole. She lets out a small moan of approval as you continue to massage her, feeling the softness of her foot beneath the thin fabric. Your hands feel warm and tingly as you rub circles on the balls of her feet, going a bit deeper now with every rotation. The scent is radiating off her foot, and you find yourself wishing you could sniff it some more. You have a job to do and you're giving your best effort, hoping to garner that approval of the pink hedgehog.
Thankfully, you're successful.
"Ohhh yeah," Amy moans, her face contorting in bliss, "You're a natural."
"You're easy to please, Amy," Tails jokes as Amy sinks further into her seat, "You think he's earned the right to sniff 'em now?"
"I dunno," the pink hedgehog teases, opening an eye to look at you, "Maybe he needs to work a little harder."
"B-but..." you plead.
"I'm kidding, I'm kidding!" Amy reassures with a gentle voice. "You did great. You deserve a reward."
She raises her right foot and pushes it against your face with more force than what Tails gave.
"Take a nice long sniff," Amy cooed.
You don't need to be told twice. Her smile never leaving her face, the image is ingrained in your mind as you close your eyes, taking a deep breath. A shiver of exhilaration shoots through your body, as the seeping sweat is starting to rub into your facial features. The smell completely surrounds your senses and sends tingles through your body. You can almost feel her soles press against your nose, not allowing you to back away.
You oblige and take another long inhale, savouring the aroma as she giggles. Your heart begins to pound against your chest and you start to feel lightheaded from the strong, sweet scent of Amy's socks, but it doesn't deter you. They smelled absolutely heavenly as you pressed your nose against the pink hedgehog's toes, a moan escaping your mouth as you savoured each second you could spend with the beautiful pair of feet. You could feel yourself swelling up as you continued to smell her feet, its scent intoxicating. Your heart beats loudly in your ears as you continue to worship them.
Before long, Amy removes her feet from your face, much to your disappointment. How long had you been at her feet? You're still lost in the moment as Tails and Amy both chuckle at your expression.
"A-Amy..." you whimper.
"Oh, we're not done yet," the pink hedgehog replies, grinning, "Not by a long shot."
"Y-You mean..."
"Yes," Tails responded, his voice low but with a seductive smile on his face, "We've got plenty more for you. After all, we have the whole day to ourselves!"
A gulp escapes your mouth, as a shiver of anticipation shoots up your body. Tails places a hand on your shoulder reassuringly, nodding with a slight smile. Your chest tightens a bit, nervous.
"In fact, I think it's time these socks came off, don't you think, Amy?"
"Definitely," Amy agrees, a sinister smile growing on her face, "It's only right for our birthday guest here to the honours, Tails."
Just then, you sense a mischievous idea flashing in Tails head, as a confident smirk appears on his face. The pink hedgehog can't help but smile even more, feeling that sudden energy.
"But let's make this interesting. I want you to remove them without using your hands."
Without saying a word, you watch the two-tailed fox stick out his socked foot towards you, but only halfway this time as if signifying that you need to close the rest of the distance. It's obvious what he's implying. Reluctantly, you kneel down in front of him and raise your chin closer to his toes. For only a moment, your eyes drift away and up to him, staring right into his blue half-lidded eyes and sly smug smile. As if your heart could beat any faster, you could just tell he's savouring every single second of this probably even more than you are at the moment.
Murmuring something under your breath, you close your eyes and lean forward, separating your lips as the fox's toes push past them and enter your mouth. The taste is a little bitter but not unpleasant as the two-tailed fox's dirty, socked foot presses down a little against the tip of your tongue, a soft whimper escaping from the young fox. But as much as you wanted to lavish the taste of the fox's socked foot, you still needed to get that sock off. Using your teeth, you begin to nip at the edge of the sock, biting into the fabric and slowly peeling it off the fox's foot, moving back more and more as the sock slowly slips off until it's completely removed from his foot.
Like a dog subservient to his master, you toss his sock to the side, and do the same thing with his other foot. Once again, your teeth bite into the sock, slowly pulling it off the young fox's foot, and once again, the sock slips off slightly easier. Perhaps the second time was easier but nevertheless, both the socks have now been removed and his feet now fully exposed, his soles covered in a light coat of sweat and dirt.
"That's a good boy," Tails cooed, patting your head with his foot, "Now get Amy's off."
Your gaze turns over to the pink hedgehog and her socked feet are already pointed at your face. Thankfully, the scent of her feet was less potent, the only hint of stench being the sweat from her soles. Without being told twice you lean in and begin to repeat the same actions with her, nipping at the edge of the sock and slowly peeling it off her foot, before moving onto the other one and doing the exact same thing. The process was almost identical but the sock slid off more easily and before you knew it, both her socks were off, and her soles were now exposed to the open air. Musk from both Tails' and Amy's sweaty soles filled the room and you had to restrain yourself from taking a deep breath, lest they tease you for enjoying it too much.
You wish it never ended but you didn't want to seem greedy, even if it was your birthday. They've already given you a lot, and it would be unfair of you to expect anything more. That said, both the fox and the hedgehog see right through you.
"Ahhh, that feels better," Tails sighs as he leans back and stretches, his bare feet now visible for all to see, "I know that look on your face so lie down on the floor and let us use ya?"
Your face burning up, you do as the fox instructs, lying down on the floor and allowing both of them to smother you with their feet. Tails plants his right foot on your nose, curling and rubbing his toes against your nostrils while Amy keeps your lips occupied by pressing her feet against your mouth, forcing your lips open as she pushes her feet deeper inside, making you get a better taste of her toes. That combined with the smell of Tails' foot against your nose is driving you crazy. It feels so good, and smells even better, a mixture of dirt and sweat filling your nose and mouth.
"Mmm, yeah, you like that don't cha?" Tails teased, his grin only growing wider, "If you want, we can do this more often. You can submit to us y'know, be our lil' sentient foot stool~."
You can only mumble weakly as he continues to grind his slightly dirty, bare foot against your nose. You moan into the pink hedgehog's soles, a muffled sound escaping from your mouth, as her toes continue wiggling in her mouth, welcoming a thorough clean with your tongue. You're absolutely intoxicated, in ecstasy, drunk off the stink and taste from their feet, completely absorbed by the moment and the scent of their musk. No doubt they're aware of how much you love this, but it doesn't matter. All you can focus on is how lucky you are to have such an experience. 
The rest of the trip became an absolute blur, and within the next few hours you had become the fox and hedgehog's slave, worshipping their feet and being their little foot-toy. But between the haze of stinky feet, intoxicating scent, and the feeling of the two-tailed fox and the pink hedgehog's toes in your mouth, you knew that this was exactly what you wanted for your birthday.
And they were more than happy to give you the perfect present.
