You'd had a crush on the Korra ever since the day she turned up in your town. Frankly, you couldn't see how anyone couldn't fall in love with her. She had it all: gorgeous hair, gorgeous eyes, amazing legs, a great chest, and a really lovely set of muscles. You dreamt of being with her, and many times you were on the verge of walking up and introducing yourself, maybe even asking her out, but boy was she intimidating! As if it weren't enough for her to be so beautiful, she was also the Avatar, the single most famous and powerful person in the entire world, and to top it all off, she was probably the tallest person you'd ever seen, at least half a foot taller than you. She hadn't always been like that, but a few months ago she had discovered a new form of bending that could alter the size of things. Ever since then she had been using it to always be the biggest person in the room.
Still, you were content to admire her from a distance—or so you told yourself until you heard she was leaving tomorrow. You couldn't let that happen without at least trying to talk to her, so you went to the apartment she was staying at. To your surprise, the door was slightly ajar, and you pushed it open carefully. “Er, hello? Avatar Korra?” You stuck your head inside and called in. No one answered, but you thought you heard sounds coming from deeper inside.
You were starting to lose your nerve already; probably would have closed the door and gone back home, if you hadn't heard a couple voices and footsteps coming closer. Before whoever they belonged to could round the corner and see you standing there, you went inside, shut the door quietly, and held your breath.
After they passed, your attention turned to your surroundings. Korra may have been leaving tomorrow, but the apartment was still a bit of a mess. It would probably fall on the concierge to tidy up after her. There were even a bunch of clothes scattered around.
Against your best judgments you went further inside. Your heart raced as you took a discarded sock and sniffed it, filling yourself with Korra's smell. You knew it would ruin your chances with her if she caught you now, but let's be honest, your chances weren't great to begin with. This was probably the only time you'd ever get to do this, and you couldn't resist. After sniffing her sock, you did the same with her shirt, relishing the smell of her armpits, then moved on to sniffing her pants, with special focus on the crotch. You got so deep in your own fantasies of doing the same with Korra's body that you failed to notice a door open behind you, and Korra walk into the room. Why, you barely even noticed when you started shrinking, not until the fabric grew so thick and heavy in your hands you could no longer ignore it. That's when you turned around and saw Korra standing there, with outstretched hands channeling her sizebending powers at you.
Speechless, you watched as Korra and the rest of the world grew and grew, until you barely matched the height of Korra's ankles. She was huge, more than a hundred feet tall as you saw it, and that much more intimidating than she normally was; but she was also that much more gorgeous, and the sheer intensity of both emotions left you frozen in place, staring up at her. She must have just gotten out of the bath, to judge by her wet hair pulled back in a ponytail.
She crossed her arms and tapped her foot, which was totally bare. All she wore was her blue top, a pair of black panties, and the short brown skirt she usually wore. “Didn't think I'd catch myself a pervert today. Do you wanna try explaining what you're doing in here, or should we skip ahead to the part where I punish you?”
“T-this isn't what it looks like, I promise! I was... I was...” You tried to come up with any explanation, but were so overwhelmed by everything going on that you couldn't think straight.
“Just shut up. I can tell you don't have anything to say.” Korra took a step forward. Her bare foot struck the floor with so much power it felt like a tremor to you. “You know what? I'm actually glad you snuck in here. Gives me an excuse to blow off some steam.” Another step followed, and a more powerful tremor. She loomed so close to you now, when she took a third step you could only think about how much huge that foot was, and how easily it could crush you. “Heh! I just hope you last longer than the last little pervert I caught.”
She was only one step away from you now, so when she raised her foot again, you turned and bolted away as fast as your little legs could carry you, scrambling over her discarded pants and socks towards the couch. Korra laughed “Why does everyone I shrink try to run away? As if you could really escape me like that when you're smaller than a snow rat. I think shrinking you guys must make you dumber. Or maybe you were all dumb to begin with.” She dropped her foot right behind you, shaking the floor so badly you almost fell on your face. “Not that I'm complaining. That just makes it more fun to play with you tinies.”
The couch was close now, half a yard away, but before you could dive under it, Korra took another step and her foot came down right in front of you. You bumped into her ankle and bounced back before scrambling away. There was no end to your running now—you ran only because that's all you could think to do in your terror of being stomped flat by your crush.
Boom! Boom! Boom! Her feet fell all around; sometimes behind you, sometimes at your sides, sometimes right in front. Other times Korra held her foot over your little head and challenged you to get away in time. Nothing had ever scared you so much in your life. Your blood was filled with adrenaline, keeping you alert enough to dodge all her casual steps, but just a few minutes later your legs were already slowing down. BOOM! You avoided another step by half an inch, but in throwing yourself away you stumbled and landed on your face. Before you could get back up, Korra's foot slid onto you, warm and strong and far too heavy to lift.
“Enough games, little man. Now it's time for your punishment.” From heel to toes, her foot measured more than twice your height. It covered you completely, and easily turned you over, keeping your face smothered into her sole. It would have been thrilling, if you hadn't been suffocating down there. You struggled with all your might, but could hardly move.
The good news was it seemed that Korra wasn't trying to crush you. Eventually she pulled back her foot, just far enough that your head poked out between her toes and you could start taking deep breaths to recover. “Alright, perv, this is how it's going to go.” Korra wiggled her toes around your head. “I'm going to keep you at my feet until I decide you learned your lesson. You're gonna be my insole when I go out, and at home you'll rub and kiss them. Got it? Or should I say it slower so your tiny brain can understand?”
“I-I got it!” you hurried to say as soon as her toes released your head.
“Then prove it. Get to work, tiny!” Her toes closed over your head, resting on your face without smothering it, and you quickly puckered your lips and started kissing them, also bringing your arms around to rub her heavy sole. You worked really hard at first so she wouldn't be angry with you. It was a huge relief when Korra praised your work. “Not bad, tiny. You're lucky I just took a bath, though. Later we'll see if you can stand my feet when they've worked up a sweat.”
You relaxed a bit after that, slowed down your kissing by half and rubbed your hands more thoroughly over her skin. It was... nice. Korra freshly-washed sole felt great resting on your body; its soft aroma had you hooked, as did the taste of her skin when you dared to lick it. You never dreamt you would be so close to her; maybe it hadn't been such a bad idea to come sneak in her room and sniff her clothes after all. Now you would get to spend a lot more time with her—days at least, maybe months or even years, happily at her feet. Serving as her insole might be tough, but you figured you could put up with it for her sake. You would devote yourself completely to her feet, even worship them if she asked. Already you were quietly doing just that.
Korra moved her foot after a while, letting you kiss another pair of toes. This time you could look out beyond them at the rest of her body, especially her wonderful bronze legs with their shapely calves and muscular thighs, and the pair of panties under her short skirt. What a goddess she was, and how lucky you were to have ended up in her possession. Already you were thinking this would be the most wonderful time of your life.
But rather than her legs, you really should have been paying more attention to her face. “No way. Are you actually enjoying this?” Korra said, and pulled back her foot to get a clearer look at your face. “You are! You're into all this! Ugh!” Suddenly her foot pressed down so hard it squeezed all the air out of your lungs. Panicking you put your hands on her toes and tried to push them off, but they were far, far stronger than you. “I can't believe I let you get off to kissing my foot. This was supposed to be your punishment. Now I have to think of something else to do with you.”
Korra spent a while thinking it over, but when her stomach growled, she looked at you like she had an epiphany. “You know what? I think I know just what to do with you.” She bent over and snatched you up, holding you tight in her fist.
“W-wait, please, I'm sorry!” you squeaked, until she put her thumb over your mouth and silenced you. Then she started to grow before your very eyes.
She grew so tall her head almost bumped into the ceiling, then shrank you even smaller. In the end you were barely half the size of her fingers. It looked like she really enjoyed it. Then she looked at you again, and licked her lips. “Hey, tiny, you don't want to be eaten, do you?” As soon as she let you speak you begged her, crying, to spare your life. Then she silenced you with a thumb bigger than your whole body. “Good; then you definitely won't enjoy this punishment. Heh! I always wondered what it'd be like to eat a person. Guess I'll find out, thanks to you.”
With that she tossed you in her mouth and shut it after you. Her tongue flattened you to the roof of her mouth, sucking on you, licking you all over while you struggled helplessly against it, crying and begging for your life, hoping that this was just a cruel trick on her part, until the moment when with one swift motion she pushed you up and back along her throat. Gulp! You went down with just a handful of spit, while Korra smiled and rubbed her tummy. “Ah! Thanks for that, tiny! Have fun becoming part of me; it's the only thing you were ever good for.” Her laughter was the last thing you heard before losing consciousness inside her, never to be seen nor heard from again.
