Let's keep it simple.
You wake up tied to your bed, gagged and bound together by makeshift rope holding your arms and legs in place. The room is dimly lit by the morning sunlight just barely seeping through your shutters, but you can see well enough to realise that someone has been in here recently. Thankfully, you aren't too badly hurt but whoever came in here has taken off all your clothes and left you naked. Your wrists and ankles are slightly sore where they were tied together, but it's nothing serious.
You grunt and try to sit up, but your muscles protest and you fall back onto the mattress. Your stomach feels like it's full of lead, and you're weak from a combination of hunger, thirst, and general lifestyle habits of playing League of Legends all night. Though, before you attempt again, you lay down for a few moments to allow your body recover. But when you're just beginning to make any headway in your escape, you hear approaching footsteps, faintly getting louder by the second. The doorknob slowly turns.
You mutter under your breath, cursing whatever God you believe or don't believe in; it doesn't matter. This was it. The end. Someone was coming for you. And there wasn't anything you could do about it. 
Your erratic thoughts get interrupted by your bedroom door opening slowly, revealing two small figures entering the room. What surprises you the most though is that they don't look human at all, so hopefully they're not going to kill you right away. You stare at them curiously as they walk towards you, their features difficult to discern in the dim light. However, your eyes adjust and you see two familiar faces looking up at you.
And you groan.
"Hey, our foot slut is finally awake!" you hear a familiar voice casually chirp.
You grumble, taking a lot of effort to lift your head off the pillow, just to maintain eye contact with this yordle. A pair of turquoise eyes stare back at you accordingly, both sparking an emotion of mischief. You recognise him all too well. He's Fizz; the same small blue yordle that managed to overpower you and made you worship his feet on a beach. The fact that he somehow found where you lived just proves how much trouble he wants to cause to you.
Fizz on the other hand looks ecstatic to see you. Grinning, he jumps on your bed and sits on your stomach, extending his two fishy feet towards your face. He flashes a smile and wiggles his webbed toes at you.
"Bet'cha wanna smell them, maybe lick 'em clean," Fizz teases, "Right?"
You glare up at him, trying to indicate that you hate him, his attitude, basically the way he's treating you like some doormat. Predictably, he ignores your concerns and giggles, moving his feet just a tiny bit closer. The smell wafts into your nostrils, causing your face to shrivel up in disgust. You turn your head away and take a deep breath, trying to ignore the stench.
The blue yordle raises an eyebrow, and his grin widens, "Aw, c'mon! I know how much you loved my feet. Especially when I rubbed them down there!"
Fizz removes his feet from your view, and shifts them towards your groin, using his toes playfully caress the tip of your cock like a cat would. You can't help but whimper softly as the sensation of those webbed toes sliding over your erection overwhelms you. It's odd, but it's also surprisingly euphoric, as if your fetish has been rekindled.
You want to protest, and attempt to wriggle away but all this does is increase the sliding movement Fizz is applying to your dick. The sensation of his feet teasing your cock is almost unbearable, and you feel your knees begin to shake. You try to focus on something else, anything else, but it's no use. You're just about to give in again, when…
"So… this is the guy you were talking about!"
You feel the pressure lessen on your member, blueballing you up instantly. Your head turns towards the unfamiliar voice in the room as your eyes drift away from the blue yordle's feet and onto his friend, another yordle, standing on your desktop chair. You note his red panda-like appearance, fit with a dark green helmet and goggles sitting on the edges of its rims. He's also wearing a red scarf covering his neck as well as leather pants, green boots, and blowgun in hand to accompany his outfit. His expression shows a mix of inquisitiveness and amusement, as if he was surprised to find you getting turned on just from his fishy friend's feet alone.
He turns his gaze to Fizz, who cockily throws his head back in pride, grin still plastered across his face, "Yeah Teemo, he's the one!"
Showing off, Fizz plunged his toes into your mouth forcing you to suck them clean. You gulp loudly, and choke slightly as the taste of his feet invades your senses.
Teemo snickers, and looks back at Fizz, ""Jeez, he really likes it!"
"How about I let you have a turn, eh?" Fizz offers, removing his toes from your mouth. He jumps off your body and lets his friend take a turn with you.
Teemo leaps off your chair and onto your bed, giving you a quizzical look. With beaming confidence, he steps on your stomach, walking all over you and leaving footprint-shaped bruises on your naked body. Eventually, he stops just shy of your neck and rests his shoed foot on your chin, moving your head so that you can gaze at him.
"So, you like feet?" Teemo teases, a tinge of evilness present in his voice. He ever so slightly lifts his green boot so that the toe cap is just perched on the edges of your lips, "Go on, lick them clean."
You bite your tongue to prevent yourself from saying anything, but your resolve crumbles under the sheer humiliation of being forced to suck on his footwear. You swallow your protests and let your tongue dart out, licking the bottom of Teemo's boot. For a few seconds, Teemo simply stands there, watching you lick his shoes so passionately. His fishy friend however isn't so good at keeping still. Instead, he laughs hard and points at you, his sharp teeth glinting in the low light while your tongue and lips made movements around the outsides of his friend's footwear.
"What did I tell ya?" Fizz exclaims, "Just one look at your boots and he's already drooling all over them."
Teemo nods to his friend, agreeing with him, "Agreed. It's like he wants to submit to us. How long have you been making him squirm under your feet?"
"Just one."
"One?"
"Aww c'mon Teemo," Fizz fake pouts, "It took me forever just to track this guy down!"
"Oh, you could've asked me to help!" Teemo laughs. Grinning, he removes his boot off your face, stepping away from you but still remains standing on your stomach. You're left panting and unable to stop yourself from staring at his feet, "I'm sure I would've helped you find him for you!"
"Well, yeah, but then it wouldn't be a surprise!"
Teemo warmly smiles at the blue yordle, knowing full well what Fizz means by that. As close friends, sometimes the best way to show your appreciation is to treat them to something. Teemo's smile turns into an outright smirk.
"I guess it's a good thing I haven't taken these off in a while," the furry yordle says with ominous intent as he places the toecap on your mouth, "I want you to keep still while I remove my boots."
You moan softly as he pushes your face against his soles, the tip of his boot pressing into your mouth, stretching it to slightly uncomfortable levels. Regardless, you gently clamp your teeth onto his boot making sure not to bite down too hard. You feel Teemo tugging, slowly but eventually getting his feet out of their small smelly prisons. The other boot soon follows, your jaw aching a little as Teemo's boots stays in your mouth, forcing you to push your tongue out and continuously clean them with your saliva.
Finally, after what seems like forever, Teemo's other foot sets free and removes his other boot, and you're left panting for fresh air. You cough, trying to catch your breath.
"There, now we can get started," Teemo purrs, "What do you say?"
You open your mouth to speak only for Teemo's foot to shove itself inside. Your eyes widen as you feel his toes curl and rub against your tongue, forcing you to lick the salty flavour of his smooth skin. You whimper softly as Teemo begins to move his feet around, shoving them in and out of your mouth, coating your tongue with the salty sweat of his feet.
"Mmmmmm..." Teemo moans, "That's it... Keep licking..."
Your tongue works overtime, lapping up every inch of his toes you can reach. Eagerly, you try to force your tongue further between his toes, licking up and down his arch and even reaching his heel. You gulp as you hear Teemo grunt, his foot resting on your chest.
"Why don't you let his nose have a sample of your boots?" Fizz idly comments, fiddling with one of the aforementioned objects with his hands. He tosses it towards Teemo, who happily catches it with ease.
Not wanting to breathe any of Teemo's foot scent that's trapped in his boot, you hold your breath and try to pull your head away, but you're weak and have very little strength. The fur-covered yordle leans towards you and brings his boot dangerously close to your face, before pressing the opening on your nose. The potent stench hits you in the face, making you try to gasp for fresh air. But with your mouth busy licking and sucking on Teemo's foot worshipingly, all you manage to do is cough and wheeze. With two of your senses overstimulated by his feetpaws, you feel your face go numb as your vision blurs.
Before you pass out into unconsciousness, Teemo's foot shifts as he takes out his saliva-coated foot, giving you a chance of breathing again. You suck in a deep breath, gasping loudly as your lungs fill with oxygen. But short-lived relief is quickly replaced by another wave of nausea and dizziness as Teemo shoves her other untouched sweaty foot into your mouth. In response, you gag and try to move away, but all you manage to do is slobber and spit all over his toes, getting the taste of his concentrated toe gunk and salty sweat all over your tongue.
On the other hand, your sense of smell keeps assaulting you by the warm humid air trapped in his green leather boots. Stuck in your muffled state of mind for your arduous task, you can only imagine how the two yordles watching you are reacting to your submissiveness. It isn't any of your business though, as despite how strong and pungent the air is, you find the feeling to be strangely not unpleasant. This, in combination with you cleaning off the filth from Teemo's feet proves to be quite the aphrodisiac for you, making you involuntarily moan in pleasure.
"Oooh! Look at you, so eager to worship my feet!" Teemo chuckles, wiggling his toes in your mouth for you, lulling you deeper into submission, "You're such a good footpet, aren't you?"
You wince a little at Teemo calling you that, despite it being less harsh than what Fizz normally calls you. Regardless, you nod and moan in agreement. Maybe your fixation was particularly strong today but at this stage, you're willing to please your new master Teemo.
"Good boy!" Teemo coos, pressing his saliva-coated foot on your groin, "Now let's see if I can make you cum."
"I dunno," Fizz teases, sticking his tongue out, "Does he really deserve it?"
You whine, your cock twitching at the thought of cumming. You want to climax so bad, even though you know you should resist. But your body doesn't want to listen, and your mind slowly goes blank. You just want give in, letting Teemo's feet guide you into overdrive. You moan softly, moaning louder as Teemo's other foot begins to rub against your cock. At first, you feel a little embarrassed, but then emotionless and obedient as Teemo's foot rubs against your shaft.
"Oh yes, that's it," Teemo moans, his voice taking on a seductive tone, "Serve me, serve my feet."
You moan loudly, and you feel your orgasm start to build inside you. The pressure is almost unbearable, and you can't help but cry out as the ropes tied to your limbs restrict your movement. Teemo's toes press harder against your tip, rubbing and teasing your sensitive skin. The sensation is too much, and you cum, your hot seed splashing against Teemo's foot and oozing down his leg. He's taken aback for a second, before giggling and smearing his cum-drenched foot on your beddings.
"Wow," Teemo says, sounding impressed. "That's quite a load."
"Yeah," Fizz chuckles, glancing over at the mess you made on yourself, "That's our footslut!"
You pant heavily, your head still fuzzy and unable to comprehend what just happened. Barely keeping yourself together, you look at Teemo, hoping he'll untie you, but he merely smirks back at you.
"Please," you whimper, tired and exhausted, "Untie me."
Teemo chuckles, standing down on the edge of your bed and folding his arms. You whimper and beg more, but Teemo simply glares down at you.
"Nah, we've got more plans for you. Right, Fizz?" Teemo asks, turning to Fizz, who nods eagerly.
"Oh yeah," Fizz agrees, dragging his feet on your bedroom floor, "We've got a lot planned for you."
And with that, the two of them leave the room, leaving you tied up on the bed.
