Liz smiled as she saw the update from her phone. The twenty-four-year-old sat on her couch, really her parent’s couch, and laid her head back to stare at the ceiling. She felt her long brown hair fall over the arms of the couch as they had a thousand times before. At this point the basement couch was essentially hers and had been since they got it when she was twelve.

She sat up, remembering all the good times she’d had on that couch. There’d been hundreds of sleepovers, her first kiss, her first horror movie, her first blowjob. Liz looked around the basement that had been her space for years, appreciative that her parents had let her continue to live with them while she earned her Master’s degree. Nowhere else would have felt like home and she wouldn’t have looked forward to getting this couch back up that staircase.

Liz was in good shape, but she definitely wasn’t up to heavy lifting. Her C-cup breasts would be in the way, and she simply looked too elegant to be seen doing any lifting.

Lately though it had been the site of other numerous firsts. With the advent of Tiny Tinder, which she’d downloaded the day it arrived, she’d checked things off her bucket list that she thought would never be possible. The first night she was on it she completed her first vore, head hanging over the edge like she had just been doing.

Once she’d masturbated to the feeling of the little man struggling in her stomach she’d even been nice and let him out. The next man went right up her butt and did as well as he could in his own personal quest: to find his way entirely through a woman’s gastrointestinal tract and come out her mouth. She’d found him the next morning in the toilet, surprisingly unharmed, and surprised as she flushed him down with a smile.

So many firsts!

Last week she’d finally decided to play the other side of the coin. Her first ‘giant’ encounter had ended with her getting covered in semen in the cupholder that divided the couch in two. Tonight she was going to extend even more trust to that giant.

She had been lucky to swipe right on this particular guy. The men who wanted shrunk never seemed to care if they met her first, but she certainly did. Twice she’d had coffee with the man who first got to play with her shrunken form, after he’d proven that he was actually a super nice guy. Too nice for a real relationship, of course, but she’d let him play with her tiny body for sure.

Liz had heard some of the horror stories that some people had gotten into with Tiny Tinder and knew she wanted no part in becoming someone’s forever toy. Not only did Grant agree to her terms and stick to them completely during their first hookup, but he’d even suggested she modify a few settings on her end to make sure nothing bad could happen on accident.

Next week she planned on making some similar suggestions to whatever guy wanted to shrink with her. Just not as well meaning. Some of the settings were difficult to understand and she was sure she could convince someone that ‘default size correction’ should be set to ‘0’ and not ‘100.’

But for now, she told herself as she called upstairs to ensure that no one else was home, I’ll just keep myself nice and safe in Grant’s balls.

She walked up the narrow stairs that led directly to the backyard and made sure the door was unlocked. The other that led to the ground floor she didn’t bother with; her family was surprisingly good about giving her privacy. Except for her brother Chris of course, but he was out on a date of his own. Her parents were just gone, which was fine with her.

Confident everything was going to plan, she checked her phone one last time and saw that Grant was only five minutes away. She started to shrug off her white work blouse when she remembered to pull a bottle of dark beer out of her mini fridge. Just like Grant had requested, and she was fine with helping him with his own fantasies, the dark beer got poured into a glass next to a little stroker that she’d picked up at the store.

Tonight would be a bit of give and take for both of them. He wanted the thrill of almost drinking someone down, she wanted to ride in his balls while he beat off. He wanted to end the night with her wallowing in his seed, and she provided a shot glass. He wasn’t particularly into cock vore, but she knew she had to do it at least once. It met both their needs tonight.

Satisfied that the table was laid out the way they’d agreed, Liz stripped down naked. Her red cheeky panties she carefully set next to the beer while the rest of her clothes she tossed into a corner. Carefully she climbed onto the coffee table, grateful her workout routine kept her slim, and tapped on her phone.

When the sensation of shrinking vibrated across her body she dropped her phone and felt herself fall. It wasn’t the best feeling in the world, but she’d paid careful attention last time.

This time when she came to, quickly hopping from her back to her feet, she was exactly where she’d intended to be: right next to the beer she’d just poured on the coffee table.

Liz took her time to marvel the world around her, having shrank several minutes before Grant was due to arrive. One day, she told herself, she’d make a match that revolved around them both shrinking and exploring the world around them. For now she ran a hand along the outside of the cold glass, kicked aside crumbs from her dinner earlier that were now the size of boulders.

Luckily for her it had been a warm day, the basement was often cold but her naked body didn’t feel cold at all.

Until her phone vibrated from far away. Liz turned reflexively to look at it, then ran after it when she saw it had vibrated its way to falling off the table. She fell to her knees when she neared the edge, laughing internally at how the two-foot fall now seemed so dangerous to her three-inch tall self. Liz focused her eyes on her phone as it vibrated again and a notification rolled across the idle screen.

“Car accident?” she read aloud as the words shown briefly. “Have to cancel!”

“Oh, son of a bitch!’ she said aloud, smacking her tiny hand on the coffee table. “Now what am I gonna do?”

She wasn’t worried about her safety or staying tiny; Grant had walked her through how to ensure she’d return to normal after several hours. For safety’s sake she’d set it to six hours. Now she just had to find a way to keep herself entertained until two in the morning.

“Here.” She said, thoroughly annoyed, “On this coffee table.”

Then she heard the last thing she’d expected: the door to upstairs creaked open and heavy footsteps moved down the stairs. Liz thought quickly and hid behind the beer; it was the only thing on the coffee table aside from crumbs and the various remotes for the television and sound system. Carefully she peeked around the side and felt her heart drop as she saw her younger brother making his way down the stairs.

“Liz, you down here?” Chris whispered loudly. He didn’t see her roll her eyes or make sure her arms were able to cover her privates. Her brother was nosy enough that there was no chance he wouldn’t see her.

I should’ve expected him to blow it on that date! She cursed herself. Usually she was very good at planning, but Chris had always been a wrench in her gears in one way or another.

“Ew, panties on the coffee table?” he said aloud, wrinkling his nose. “I thought you were the clean one!”

Without giving them much attention Chris swept the panties to the ground and sat down on the couch.

“No fair you got the big TV,” he said to himself as he picked up the remotes. His hands flew past Liz at dizzying speeds as he turned on her large television. “And who is this for?” he asked aloud as Liz watched his hand curl around the glass that was her only hiding spot. “You don’t even drink beer!”

Liz got lightheaded watching the beer rocket upward, a flying building from her perspective.

“Holy shit!” Chris yelled out as he saw his naked mini-sister on the coffee table. “Liz is that you?”

She rolled her eyes, not that he could see, and nodded her head causing her brown ringlets to fly.

“Yes it’s me you moron!” she yelled up at him.

His brown eyes looked down at her and he leaned forward, setting the beer far to the side. Liz redoubled her efforts to cover herself as Chris brought his face forward. She watched with dismay as he smiled and picked up her phone.

“You were on Tiny Tinder, weren’t you!” he said with a laugh, swiping her phone open and seeing her notifications. “Hah! And the guy bailed on you too!”

“Get out of my room you loser!” she hollered at him, though he didn’t notice. But she did notice her television was turning on and she turned even more red, knowing what was about to turn on.

Instead he kept swiping through her phone as Liz made a frustrated sound. Then she realized he could see all her messages on Tiny Tinder and her face turned red from humiliation. Knowing him he’d use this as blackmail, threatening to tell their parents if she didn’t do what he wanted! They both knew how paranoid their parents were about new technology and online dating.

“So, I’ve got an idea!” he said, injecting his voice with humor only because he knew his sister would hate it. “I’m gonna go ahead and take away your safety net.”

“What? No!” Liz screamed at him as he tapped on her phone. “You can’t do that you jerk! Turn me back!”

“Don’t bother,” Chris told her dismissively, “I can’t hear your squeaking over the sound of your…porn? You had porn ready and waiting on your TV? Oh, you’re a dirty girl Liz.”

“Stop it turn it off!” Liz forgot to cover herself in her distress and ran at one of the giant remotes as a ninety-pound girl on the television insisted she was old enough to work as a secretary.

Her giant brother just laughed and blocked her path with his giant bare feet.

“You want the remote?” he asked as he leaned forward and grabbed them, instantly taking them far out of her reach. “Well I want a foot massage while I watch Carmen here regret her life choices and enjoy this,” he took a sip, “microbrew.”

Liz looked at her brother in a rage. She’d never been so angry in her life. First her date cancelled on her, preventing her from living her cockvore fantasy, and now her brother had effectively trapped her small! And was demanding a foot rub!

He cleared his throat loudly like an avalanche on a distant mountain and raised up her phone, shaking it lightly to get her attention.

“I’m not feeling anything down there,” he reminded her as he sipped his beer and the girl on the television found herself hiding under her new manager’s desk as his wife talked to him. “I don’t mind you staying tiny forever, but you might!”

Chris knew he wouldn’t actually let her stay small. Probably. But he couldn’t lose this opportunity to really rub it in his sister’s face. She was always the example of perfection his parents had held him up to, even though she still lived in their basement. So what he was ‘only’ a mechanic? At least he lived on his own.

Which was why he loved the feeling of his sister’s tiny hands on his feet. Was she actually accomplishing much? No. But knowing how demeaning this was for her made it the best foot rub Chris could imagine.

Liz, on the other hand, was hating life. Her brother’s feet didn’t stink, but everything about this was wrong. She ran her hands up and down his feet, pressing harder when his feet shook side to side, or when he mentioned the better she did the faster she’d be back to normal.

This is the worst night of my life! Liz thought as she rubbed on her brother’s heel.

This is the best night of my life! Chris thought as his sister rubbed his heel. The beer was long gone, but the girl on the television had snuck out her new boss’s cock from his pants and was busy blowing him. Above the desk the wife gave her husband a kiss on the cheek before she left, not knowing a young girl was busy banging his cock against the back of her throat.

After a couple of minutes of watching the girl’s head bounce while her boss took phone calls Chris felt his own cock start to rise in response. Then he remembered what he’d read on Liz’s phone. Initially he’d just intended to get a foot rub and knock Liz down a notch. But how could he resist giving her what she clearly wanted?

Liz was moving on to his right foot when she felt it, that full-body tingling sensation. She was changing size again.

What? About time! she thought, believing that Chris had finally come to his senses and was returning her to full size. Then she screamed as she saw his foot grow in front of her.

When she stopped shrinking Liz guessed that she was around one-eighth of an inch tall. A crumb she would have kicked aside moments ago now came up to her hips. Liz froze in terror as she realized how small she was and Chris’s mountain-sized feet moved, a movement so massive she couldn’t help but cower.

Then she saw her brother stand, suddenly rising so far that her mind blocked out the movement until it was done. She simply couldn’t comprehend his height as she looked upward, there was nothing she could compare it to. When she’d been with Grant she’d had several drinks first, perhaps that had helped when she’d been with her first giant.

“Oh shit,” she said as she saw her brother unzip his pants and pull them halfway down, letting his cock fall free. It was the size of a train even soft, though she could see it growing.

“Great news sis!” his voice boomed down to her as he sat back down. “Since you want to be cock-food so badly I’ll happily oblige!”

Liz tried to run, but all that did was make it easier for Chris to see her tiny form. Gently he pinched her between his fingertips and brought her up to face level.

“For the record sis,” he started, “I was gonna stop at the foot thing, but how could anyone resist this?”

Chris turned his hand so that she could see the scene on the TV. On the distant mountain the tiny girl was getting slammed from behind while bent over the desk. The cameraman made sure to get an angle that showed her feet not touching the ground as her butthole was getting stretched far beyond what it should have been.

“So it’s kinda your fault I’m all turned on,” he said apologetically before leaning back on the couch and holding his hard cock straight up.

Liz screamed as she looked down.

“No, not like this!” she yelled as her brother lowered her down to his urethra.

It bounced with each pulse of his heartbeat and his fingers spread the opening wide like a hungry mouth. There was a faint glistening as precum started to leak out, lubricating his passageway. Chris laughed as he felt her kick at his fingertips; her strongest effort was a mere tingle to him.

“Have fun!” he said as he grinned, carefully placing Liz’s tiny form in his urethra. She sank in immediately, pulled by fluids she’d hoped she’d only ever tasted from someone else. When he released her he looked down at his cock like the barrel of a rifle.

“Don’t worry sis,” he told her, “I’ll give you an hour of fun before I let you out. I’d hate to ruin your fantasy!”

Liz screamed angrily at him as she felt his urethra grab her waist and start gently pulling her down.

This is not how tonight was supposed to go! she thought to herself as she got one last view of her smiling brother before she was swallowed by his cock. She’d read about it before, sure, but she still didn’t understand how her body was sliding down his rod, or how she didn’t need to breath as she felt herself move further into her brother’s dick.

She tried to climb out with her arms and legs though she knew it was futile, and twenty seconds after her sticky descent began, she felt her legs open up into a large open space. Just as she realized what was happening, she dropped the rest of the way into Chris’s ballsack. There was a moment of weightlessness, then Liz landed in a pile of fluids, getting some in her mouth when she grunted from the impact.

“Let me out!” she yelled as spit and sloshed her way to the side of the ballsack, punching against her brother’s skin.

Chris moaned as he felt his sister descend through his dick and let out a little shout when she dropped into his testicles.

“Holy shit this is amazing!” he said to himself, carefully keeping his hand off his cock. “I need to start using this app myself!”

As he looked his ballsack jumped and twisted with each blow his sister rained threw in his testes. The sensation was indescribable, and as much as Chris wanted to stroke himself until he came, he knew he wanted this feeling to last. So he carefully tucked his hard cock back into his pants, paused the porn as the manager started to push a water bottle into her tiny pussy while he railed her backdoor, and slowly walked upstairs.

Liz soon exhausted herself, first fighting against his swinging balls as he walked, then simply staying upright amid the fluids she was surrounded in. She fell frequently, at times because he simply was walking, at others because the crotch of his pants moved and moved his testicles for him. Once because he idly scratched himself while he sat on the couch, checking his phone, or reading through her own message and past hookups.

Every one of his movements was a world-shaking event for her. Part of her realized that she would actually be having a lot of fun with this…

If it wasn’t my goddamn brother! she thought angrily as another motion sent her to her knees. This would be awesome but my first time is completely ruined by this asshole!

Chris, meanwhile, did his best to act normal when his parents returned home. They didn’t need to know he currently had his sister tucked away in his ball sack, and he left both his and his sister’s phones on the kitchen table as he jumped up to help them with groceries. Liz screamed as his balls flew back and forth, and Chris smiled as he felt her movements.

I’m definitely gonna find another gal that’s into this, he told himself as he sat a bag of groceries on the kitchen table.

Thinking to put her phone somewhere a little more out of the way, Liz’s mother picked it up and saw that it was flashing a notification. Automatically she turned it on and immediately was taken aback by what she saw.

“No!” Liz’s mother said as she saw the Tiny Tinder app on her daughter’s phone. She had a deathly fear of online dating and couldn’t stand to see her daughter using it. Especially one with such a sordid reputation as this.

Quickly she opened the app and averted her eyes from the picture of a male member that immediately popped up for review. She tapped on the ‘profile’ button and quickly scrolled to the bottom.

“No daughter of mine is going to use this trash,” she said as she deleted Liz’s profile, then uninstalled the app to be double sure.

Chris peeked over her shoulder as she was clearing Liz’s phone of that darned app and briefly panicked, but he couldn’t think of a good reason to step in and stop her. Surely he could fix it later, right?

When all the groceries were unloaded, Chris excused himself to the upstairs bathroom. It had been an hour, and he knew if he kept her in his balls much longer his parents would start to question why she hadn’t come up to greet them. Sure she basically had her own apartment downstairs, but she’d left her phone on the table. She’d be looking for it momentarily, they thought, and her mother was planning a lecture on the perils of hookup apps.

Liz’s brother parked himself on the toilet seat as she renewed her struggling. He felt a little awkward beating off in the bathroom like he was sixteen again, but she needed to come out. Both because that last hour had definitely been a good way for Chris to humiliate his sister, and also because her moving in his balls felt so good he was about to shoot in his pants.

He pulled his cock out of his pants and slipped off one of his socks. Chris was hard in an instant and he caressed his ballsack, doing his best to feel Liz’s tiny form while he stroked himself. It didn’t take long for him to feel his orgasm approaching; the dirtiness of the situation combined with the sensation of something wriggling in his balls was incredible.

Two minutes after he started Chris felt it approaching. His balls drew up and he felt a strange tightening down below; some part of him was pulling Liz right along with his jizz. Knowing his sister was swimming in his seed, and how much she must have hated it, Chris pumped furiously and shot his load into the waiting sock.

It took effort for him not to cry out; Liz’s body pushed back the flood of semen just long enough to enhance the feeling of his explosion. She flew out of his cock with the first jet, coughing and screaming as she flew threw the air. Before she’d recovered enough to realize where she was, Chris was carefully aiming his cock directly at her.

She got off one good scream as she saw her brother’s cock pointed at her like a tank barrel before a second blast of jizz covered her entire body. Chris was careful to keep spraying her as long as he was able to cum, and carefully cupped his hand to make sure none of the jizz (or his sister) could leak out and fall on the floor. When he felt he was spent he carefully wiped the leaking tip of his cock on the sock and balled it up.

“Damn you were good sis,” he said, holding the sock near his mouth and speaking quietly.

Then he carefully snuck downstairs, snagging Liz’s phone from where his mother had left it on the kitchen table, and made his way down to Liz’s basement apartment. Once he was there he let the television keep playing, where the tiny girl was now being double-penetrated by a cock in the rear and a water bottle in her pussy.

“Man you watch some freaky shit sis,” he said as he sat the heavy sock down and unrolled it.

Chris ignored his sister as she tried to pull herself free of his jizz which was already hardening around her. Instead he focused on her phone, first finding the app again, then opening it.

“So, Mom deleted the app and your profile sis,” Liz heard as she coughed up copious amounts of her brother’s seed. Fear suddenly outweighed her disgust at what had just happened.

Am I stuck like this forever? she thought, suddenly terrified. Grant had told her the worst thing to do would be to delete the app while she was still tiny.

In the basement’s silence Chris located his sister’s profile and prepared to reload it.

Then he remembered how his testicles had felt with her clamoring inside of them.

His finger wavered over the ‘Account Recovery’ option as he felt blood start to rush to his cock again. Liz looked up from the jizz she was swimming in and saw his eyes flash between her and her phone.

Across the street, a child flipped a coin in the air, but got distracted by a bird, never seeing where the coin landed.
