Natalie had suffered from the shrinking disease ever since she was young. Her condition affected her at the most unpredictable times, reducing her to such tiny sizes that she often went unnoticed by her peers for hours at a time, scurrying under their feet like a bug and trying to get their attention, or to get somewhere safe from them.

That was just how the young woman found herself this Sunday morning. Her condition had triggered right after breakfast, and now she stood a thousandth of her normal size, lost on the living room floor and slowly making her way to the kitchen where she could hear her mother Martha doing the dishes.

Nat had been walking for several minutes and still hadn't reached the kitchen when she felt and heard the familiar rumbling booms of a normal person's lumbering steps. Seconds later, Martha appeared in front of her, a middle-aged colossus walking right towards her.

Martha was short, even for a Latina, though she made up for it by being large in other ways. Natalie had grown used to looking down on her mother ever since she turned fourteen, but her shrinking disease ensured she was still used to looking up at her too. Still, Martha's sky-scraping heights were no less impressive today than they had been the last hundred times.

It never failed to take Natalie's breath away when she saw a normal person after shrinking once again. All them became walking mountains to her, capable of shaking the world with their mere footsteps, and Martha was no exception. Had she been this size from birth she would have no doubt thought the woman a goddess. Even knowing she it was only her mother, Nat was still awed seeing her come closer in her tight blue jeans and flowery blouse, and especially when that caramel sole filled her view.

Nat shut her eyes moments before the familiar heft of her mother's foot slammed onto her and left her sprawled out underneath. Her groan was swallowed up by the wrinkly flesh, and barely reached her ears before she was ferried away on a little patch of skin near the base of Martha's big toe. Step after step numbed her body as Martha walked to her room. Natalie was almost passed out when she found herself smothered onto another surface, one no less familiar than the cold tiles she'd been dashed again all this time: the insole of Martha's flats.

Worn though it was, the leather surface was a huge improvement over the bare floor, easing some of the pressure. She couldn't say she was glad to be here and not in Martha's hand or still out on the floor, but she could make do with it, at least. At this point, the grimy imprint of her mother's foot felt almost like a second home to her. The smell was nostalgic, almost comforting, as was the warmth already seeping into the surface and into herself. As recently as two years ago she would have fought it, and tried to make her mother notice her, but she was older now and knew from experience that she was far beneath the older woman's notice.

Hours of numbness awaited Natalie while her mother saw to the chores, sweeping, mopping, scrubbing, and washing. Sometimes she was stuck to Martha's foot, sometimes to her insole, but always to one of the two. When Martha slipped off her shoes, Natalie still lay plastered to the insole, and it took minutes of struggling before she came unglued. Covered in a thin coat of grime, she crawled out of the toe box and into the light.

They were out on the veranda now, she saw. Her mother sat cross-legged on one of the cushioned chairs, a book in one hand and a cold beverage in the other, utterly oblivious to the little bug beneath her. Some small distance away, her bare foot rested on the ground, motionless save for the occasional tap of her toes. As soon a she could stand, Nat got up and jogged towards it, leaping over little cracks on the floorboards and circling around pebbles until she reached her mother's toes. There she jumped on the big toe, a hundred-foot-tall colossus, and clambered up Martha's skin to reach the toenail. Martha might have noticed her then if she glanced down—her daughter's lighter skin and sky-blue dress, specially made to change size with her when she shrank, would have stood out sharply against the deep maroon of her toenail—but her thoughts could not be further from Natalie.

The tiny woman considered climbing up to get her mother's attention, but she dismissed the idea. It wasn't as if that would get her any closer to her normal size, and at this point it probably wasn't worth the effort. She'd learned it was sometimes better to accept her shrinking and try to eke out a bit of comfort in the margins of everyone else's daily lives, and she figured this was one such time. She lay down on her mother's toenail, closed her eyes, and breathed deeply, basking in the morning sunlight that still reached her from under the awning.

It was a quiet time for her, and whatever happened, she took it all in stride. Even the little movements of Martha's toes that were never quite enough to throw her off. The smell of her mother's foot was still a bit sharp, but it softened after a while, and the sun-kissed scent that replaced it was relaxing in a way. She might have fallen asleep, if she hadn't heard her name called just then. “Natalie, is that you?” Her eyes fluttered open in time to see those massive fingers descending towards her. Their fingertips fell on the toenail, then came together to pinch her minute body. Her mother's flesh nearly engulfed her as she was lifted far into the sky, to gaze into a shimmering brown eye whose pupil she could drown in “Really, Natalie? Shrinking again already? Honey, we just went through this five days ago.” Martha shook her head in disappointment, as if Natalie had any control over her shrinking. In all her time researching the topic, Natalie had never heard anything credible saying it was possible, but her mother had cleaved to that belief as if proven fact ever since one of her friends made an offhand comment about it years ago.

More than that, Martha believed that every situation Nat got herself into happened of her will, as if the young woman chose to be stepped on or to end up in her shoes. Finding her daughter napping peacefully on her toenail certainly wouldn't help erase that impression, but then, it was likely that nothing ever would.

Martha sighed. “Well, it is the weekend, so I suppose it's fine. You can stay there if you want.” She bent over and dropped Natalie back on top of her foot. The tiny woman rolled and bounced down the gentle slope until she was caught between a pair of toes. Looking down at her daughter, Martha slowly wiggled her toes, watching how the tiny woman was pushed up and down along her skin. “Actually, I was hoping you could help me pick out some new shoes today... you can still help me at that size, can't you?” She curled her toes around Natalie, and their flesh engulfed her daughter, claiming Nat for her own. She didn't bother waiting for an answer before putting down her book and drink and slipping her shoes back on, leaving Nat in the dark once more.

It was tight in there, tight enough for Martha's toes to keep a firm grip on her without even trying. Nat could hardly move, and everything but her head was entombed between those walls of flesh. Martha went straight to the car, and in a couple minutes they were on their way to the shoe store.

Natalie wouldn't get another whiff of fresh air until some time later, when Martha sat and took off her flats. The older woman splayed her toes to let Natalie fall from them, but the thin layer of sweat and toe grime still held her daughter in place until Martha wiggled her toes together, finally rubbing Nat off her skin.

“Are you wake, Natalie?” Martha watched her tiny daughter struggle to stand, numb all over from being squeezed for hours between her toes. “Good! I have some shoes here to try on and I want you to tell me what you think of them.” She started out with a pair of leather sandals with four criss-crossing straps. Once she had them on, Martha stood with her feet flanking her tiny daughter. The soles of those sandals alone were close to ten times taller than Natalie, who gazed up at the gargantuan constructs and her mother's equally-massive feet, feeling humbled by their immense size, and the speed and power with which they moved. “What do you think? Do I look sexy?” she asked, moving her feet in all manner of ways so Natalie could see them from every angle. Natalie didn't say anything, and Martha wouldn't have heard her if she did, but then, she didn't really care. She just wanted to show off for someone, and that someone being tiny little Nat only made it more fun. “Tell me how it looks from below. Knowing you you'll probably want to see it from that angle very often.” Martha chuckled as she raised her foot over her little daughter, immersing the girl in the shadow of her foot. Natalie braced herself for impact, just in case. Her eyes dutifully followed that sandal as it swayed teasingly from side to side. Finally the sole started falling towards her, but Martha pulled back her foot before she could step on her Natalie, and instead the tip of her sandal came down safely a centimeter in front of the little woman.

“Now that I think about it, you should have a look at them from inside too. I mean, you might be riding in them sometime, so you might as well see how comfortable they are,” Martha said. It wasn't phrased like an order, but Natalie knew to take it for one and went to climb on the sandal. If she didn't, her mom would probably just pick her up and drop her on it anyways.

Martha's toes wiggled slowly as her tiny daughter climbed up the sandal's sole. From Martha's perspective it seemed very smooth, but at Nat's meager size there were enough imperfections on it to make for a manageable climb, if not an easy one as the powerful impact of her mother's wiggling toes overhead made it harder than it had to be. Still, she soon pulled herself up onto the insole, where she was met with yet another toe wiggle that spoke of Martha's amusement at seeing how adorably puny her daughter looked down at her feet.

“So, how is it? Soft enough for you?” Natalie ran her hands over the leathery surface. It was definitely softer than her mother's flats, if only because it hadn't been worn by use yet. “Maybe you need a closer look to decide. Here, let me help you.” Raising her toes and tilting back her foot, Martha sent Natalie rolling down the slope of her insole until she was wedged under the ball of her mother's foot. She set her foot back down then, smothering little Nat underneath. Softer insole or not, the pressure was no less numbing, and Nat lay helplessly under Martha until her mother took off the sandals and ran her sole over the carpeted floor, scraping off the tiny woman.

Natalie had barely recovered when her mother presented her with the next set of footwear, a pair of white ankle strap heels that hardly covered an inch of her skin. “Look, Nat! Now your mom's a real giant!” Martha laughed, towering proudly over the little bug. The shoes added some six inches to her height, further exacerbating the sheer difference in size between mother and daughter. She set her foot down so Natalie stood under the arch, gawking at the 500-foot-tall heel. “Can you imagine climbing these babies? Maybe I should get these so you'll stop getting into my shoes while I'm not looking. Oh, who am I kidding! I'm sure you'll find a way to climb them regardless. But for now, let me give you a lift.” She grabbed her daughter and dropped her on her big toenail, from where Natalie gawked at the top of her mother's foot stretching almost vertically overhead. The tiny woman clung to that toenail as her mom turned her foot from side to side, then followed it out of that heel and into a pair of fuzzy pink sandals.

She followed mom's foot into pumps and stilettos and running shoes, gawked at her massive wedge heels and flip-flops and loafers, until Martha had gone through the whole stack of footwear she had brought with her. Martha left her daughter lying on the floor between her bare feet while she decided on which shoes to buy, casually rocking Natalie's world with every thoughtful tap of her foot. Finally she made her decision and dropped her toes on Natalie, trapping the tiny woman with a curl of her toes to carry her back into her flats.

It was another few hours before Nat was taken out of her prison on the bottom of her mother's second toe. “There you are,” said Martha, peeling her daughter off with a long, maroon nail. “Did you have fun? It's not every day you get to go out at that size. Maybe I should change that, though; that was way more fun than I thought it would be! Are you wondering which shoes I bought? Let me show you!” Martha carried Natalie down, down, down, and dropped the tiny woman on a vaguely familiar surface. It took her a moment to realize she was on the skyscraper-sized white heels from earlier. “Ta-da! Since you like shoes so much, I figured, the more shoe the better, right? And, since you were so well behaved at the store, I figure you can hang out on these as much as you like today—a little reward for my little girl!” Her mother's caramel sole appeared over Nat, giant toes touching down on the insole and sliding forward until they had gained possession of the tiny woman again. After putting on both shoes, Martha stood and took a few steps, admiring how good they looked on her. She couldn't feel her Natalie down there, but she was sure her little bug of a daughter was ecstatic to be smothered under her. What better treat for such an incorrigible foot lover than Martha's own gorgeous soles? She still didn't get her daughter's interest in them, but she supposed it was harmless enough, and if it made her happy, why not help her indulge in it? As long as she could have a little fun with it too, of course.

Martha barely noticed when she stepped on her shrunken daughter. Tiny little Natalie left even less of an impression on her mother's sole and mind than a breadcrumb would have, and Martha forgot all about her as soon as she felt her.

The tiny woman would keep her sole company for hours afterwards, getting smothered underfoot or dashed against the floor over and over again, until Martha, sitting down to watch TV, brought her foot up on her lap and started idly scratching it. Her long, red nails slid over her sole until they found and picked out a tiny little thing. She was about to flick it away, until she recognized that pathetic figure.

“So that's where you've been,” she muttered, watching as her little ant of a daughter slowly stirred in her grip, looking so pitifully dirty and disheveled after all that time underfoot. “You just can't keep away from my soles, can you?” Martha grinned as she rolled the tiny woman between her fingertips, easily smothering her from head to toes. “I might have to start charging you by the hour to stay with them.” For a second Martha considered putting Natalie back on her sole, but when she loosened her grip a little to see Nat's little face again, her eyes flicked down to the cleavage that her low-cut black top left fully exposed.“Or maybe you should spend time with some other part of me, see if you like it any better. I think I have the perfect place for you right here.” When Martha moved Natalie closer to her gargantuan face, red lips parted in a grin that showed off her pearly whites, the tiny woman feared that she was headed for her mom's mouth. She never thought that Martha was about to drop her in a very different place, not until she was already bouncing down the inner faces of those giant breasts. Soon she was wedged at the bottom of that chasm, staring up at that part of the outside world she could see beyond her mother's mountainous E-cups.

Martha's chuckles made her daughter's world quake and sent little Nat a tiny bit deeper into her cleavage. Heavy flesh all but engulfed Natalie. Its warmth suffused her body. She pushed against it, but she was nothing next to those heaving mounds, and all it took was Martha crossing her arms underneath for Natalie to be flattened in between them. “Perfect. Now just stay put while I finish watching my show.” Martha's voice resounded in her cleavage, the vibration utterly dominating her daughter. Nat groaned, but there was nothing she could do. She spent several minutes trapped there, until Martha dropped her arms and let her breasts hang freely again. They separated just enough to let Nat see her immense mother's face above, already back to ignoring her as if she didn't even exist. She tried to wriggle free, but Martha's skin had captured her. It took a long time to extract herself from it, and in the meantime Martha glanced down from time to time, surveying her daughter's struggles with delight and putting a little bounce in her breasts to tease her.

Natalie was blushing the entire time. She would rather be back down under her mom's foot than here with these huge breasts shoved in her face. Even at her normal size, Martha's chest put hers to shame. To see them blown up to such a monstrous size, to find herself so casually dominated by their immense mass, made a total mockery of her as a woman. She wanted nothing more than to escape them.

Once she was no longer wedged in the walls of caramel warmth, Natalie started climbing out of the monstrous cleavage. Martha's skin was almost vertical down there, but that slight stickiness of human skin, so much more noticeable to a tiny thing like Nat, let her continue without much issue. Even when those tits wobbled at Martha's slightest movement, Natalie only had to lie flat against them to ensure she wouldn't fall.

“Enjoying yourself?” Martha asked with a wink and a giggle. It was all Nat could do just to cling to the jiggling flesh and hope she wouldn't fall down. “You've come a long way from when you were stuck between my boobies, haven't you? A whole three inches! It's almost nothing to me, but I'm sure it must feel like a lot to you, isn't that right? I mean, you started so long ago and you still haven't made it to the top. So adorable how you're putting in all that effort for such a little thing. I'm sure you must have really wanted to make it up there. Well, maybe you'll get your chance later, but now my show's over and it's time for some errands. Of course, you can come along with me too. I just need to leave you somewhere safe.

Everything jiggled as Martha's hand came to rest on her boob, and still more when an outstretched finger slid down the rounded slope of that breast to fall on Nat. A little pressure was all Martha needed to collect her daughter onto her fingertip. She held Nat to her eye, and found the tiny woman all splayed out on that wrinkly, grooved skin. Martha gave her a kiss, smothering Natalie against her lip, then tugged at her top and her bra and swiped her daughter off inside.

Her bra and shirt fell back into place, holding Natalie to her mom's tit. The tiny woman tried to see how much she could move, but as she did, the flesh stirred and pushed against her, pinning her down even more forcefully—Martha's nipple growing embarrassingly erect.

“Mmmm,” the older woman muttered as she groped herself.  Nat was usually too small to be felt at this size, but here on one of Martha's sensitive points her tiny movements felt delightfully ticklish. Martha tweaked her nipple, teasing it to its maximum size. “There we go,” she chuckled. “Now you'll be staying put for sure.” Her breasts heaved as she stood. They bounced as she walked, transmitted to her every one of Martha's movements, making her a victim of each. It all kept her rubbing against Martha's nipple, and kept that nipple firm and erect, its pressure effortlessly dominating her. All she could do was contemplate her own insignificance next to her mother's magnificent mammaries, feeling like nothing but a mole on Martha's boob.

It took a long time for that nipple to shrink and soften again. Natalie found that she could move a little bit once that pressure on her was eased, and she tried to at least crawl away from Martha's nipple, but it hardened again when she moved too quick. After waiting for it to shrink back, she made it out by going slowly, and stopped when she was safely past her mom's areola.

It wasn't much longer before Martha returned home after her shopping. Once she'd put everything away, she went to her room where she took off both top and bra to find Natalie clinging to the upper slope of her boob. She giggled. “Having a good nap? Come here, I have something to show you.” She collected Nat with her fingertips, and after a short trip, Nat found herself dropped on a hard, metallic surface. Before she could get a handle on what was happening, Martha's finger push a cage door down above her until it clicked, shutting her in this tight metal cage, barely big enough for a single shrinker.

Martha pulled up the silver chain from which hung her daughter's cage, peering in at Natalie as the tiny woman swung to and fro before her eyes. The bottom of it was a solid disk of metal, and the back of it was closed off too. The front side was a curved door of metal bars, too densely packed for anything more than an arm to fit through them. Natalie gripped those bars to keep her balance as her cage swung from its chain, and peered out in terror at her mother's amused eyes. “A perfect fit.” Martha held the cage between her fingers, turning it all around to admire the workmanship. “Now let's see how it looks on me.” Martha put on the necklace, lowering Nat's cage down into her cleavage, where it settled against her sternum in the depths between those breasts. Natalie looked out from those depths, seeing the mirror appear in the distance beyond those breasts, and her mother's reflection with it. It was the cleavage Natalie stared at in that reflection. At this distance she couldn't even see herself in there. Never before in all the times she'd shrunk had she felt so much like an insignificant nothing than she did right then. Natalie tried to push the door open when Martha released it, but the clasp was shut too tight; she was trapped.

But Martha couldn't care less about what her daughter was feeling. “You look dazzling on me, honey!” She raised her hands to where the chain hung on her collarbones, gently adjusting it until she was satisfied. “I think I'll go topless so I can look at you whenever I want. You don't mind, do you, Nat?” She didn't bother listening for an answer before going turning around and going for a walk around the house, staring all the while at her little ant of a daughter hanging between her breasts. She hadn't felt this excited in ages; she had never felt this powerful before and she was loving it! She had definitely made the right choice buying this necklace. If only she'd know sooner how much fun she could be having with Nat when she shrank, she wouldn't have spent so much time ignoring the tiny thing.

Martha rocked her torso from side to side, delighting in every impact of that little cage against her breasts. She held her tits and squeezed them together, their flesh bulging against the metal bars. She put on old hits and danced like she was a teen again, breasts swinging almost as wildly as her arms. Soon the bottle of wine she'd brought back was out and uncorked, glugging its contents into a tall, rounded cup.

Sweet red drops fell from her chin as she was chugging down the second cupful, and dripped down to her chest, flowing down her cleavage and onto Nat's cage. It soaked the shrinker's clothes, and made her woozy with the smell of alcohol. “Whoops!” Martha giggled afterwards. “Sorry about that. Let me clean you right up.” Natalie's cage was suddenly pulled upwards, and as it spun around the shrinker found herself level with her mother's face. Martha's cheeks were flush already, and when she opened her mouth, her breath was heavy with the smell of wine. The alcohol made Natalie dizzy again, and she didn't quite understand why her mother's mouth seemed to be growing bigger and bigger, not until she was lowered into Martha's maw.

Her mother's tongue took the little cage and started playing with it at once. Spit covered the cage, and oozed between the bars to reach Natalie sitting at the bottom. Even knowing she was safe inside her cage, Nat was terrified by the ease with which Martha's tongue handled her cage, and by the loud, sloppy noises of it sloshing around in her mouth. Her mom wouldn't eat her, she knew, but how could she feel safe while at the mercy of this monstrous tongue, or while those horrible teeth outside clinked against her cage? She was so relieved when she was finally pulled out again, even if only to be pressed against Martha's nipple.

“Mmmph!” Martha moaned as she rubbed the tiny cage into her nipple. “So nice. Isn't this nice, dear? I haven't felt this close to you in a long time. Do you like being this close to mother? Ha-ha! I'm so happy I bought this necklace for us! Now you can be with me wherever I go, and you don't even need to be under my foot for it. But maybe you miss my feet? He-he! Well, I can help you with that too!” Martha plodded to the couch, where she bluntly dropped her ass on the cushion, giggling as she held the cage and necklace in her fist. When she opened her hand, she unclasped the cage from the necklace, holding the clasp between her fingernails and giving it a little shake, laughing as it jostled her puny daughter. Then she lowered the cage and dropped it on the floor. It landed on its base before falling back, rolling twice and coming to a halt in a little nook between two floor tiles. Her mother was almost all that Natalie could see looking out of there, even before Martha brought her meaty, wrinkly soles over the tiny woman. Toes wiggled and soles scrunched overhead, showing off incredible power. Big toes nudged her cage around with ease, sending it rolling this way and that, or fell on it to hold it still, flesh covering the door to Nat's cage. Then those toes seized her, and smothered her nonstop.

For a while, Nat knew nothing save her mother's feet and her voice somewhere far away. She could hear Martha giggling over her, and sighing from time to time. Then came the moans, becoming more and more frequent, her breathing louder and more intent. It sounded like she was...

Natalie flushed all over, and shivered at the thought that her mother could be using her like this. Even being drunk was be no excuse! She could have been mistaken, but what other explanation was there for these sounds? When Martha finished and picked her out, the smell of those giant fingers further confirmed what Nat had already known. The tiny woman was given a kiss, then clumsily clasped back onto Martha's necklace. For the rest of the evening, Martha was content to lounge in the living room, watching her shows and occasionally playing with Natalie's cage, just nudging it with a nail or flicking it back and forth, amused just to see how easy it was to toy with Natalie at that size, softly chuckling at the sight of that little creature lying behind those bars.

All that time, Natalie tried her best to open her cage. She knew she should have grown back already since she'd shrunk so early today, but the cage was stopping her—a shrinker could never grow back if they lacked the room for it. She couldn't even make it budge, though, and if she'd made any progress at all, it was surely all undone when Martha gripped the cage again to unclasp it from the necklace before bed. Martha dropped the tiny thing in her navel when she went to sleep, bidding her daughter good night. Natalie spent another two hours trying to break free, but eventually exhaustion ended her efforts, and she fell into an uneasy sleep, cradled in the belly of her godly mother.
