The well dressed man stood in front of the Johnson family holding a small disk looking object. Jimmy stood between his younger sister, Kat, and his parents and they all looked nervous.

“As you have probably heard, there was an incident with a student at your school a few months ago that triggered the shrink effect. The nanobots in the kid's body malfunctioned, and sent out a signal to everyone within up to 90 foot radius, that will cause the nanobots to rapidly multiply until they finally burn up and shrink the host.”

“So these stupid injections we had to get are gonna cause us to shrink? I thought these nanobots were supposed to make us healthier?” Kat said angrily. She was known for her attitude. Much to Jimmy's chagrin, she fit into the ‘big titty goth girl’ category, and the recent popularity of that type made him the center of a lot of teasing. He had accidentally seen the size on her bra cup when doing laundry once, and knew she was a 34F. Adding that to her raven black hair, and unknown number of piercings, and she fit the title perfectly.

“Well one of the benefits of them is that at your smaller size, they will be much more effective, so you will be faster, stronger, and heal as fast as a superhero, when you shrink. Although, it's proportional to your size, so don't expect to be lifting up cars. You'll just be able to do more pushups and pullups, and the like.”

“Oh, well that's good I guess.” Their mom said with a nervous smile.

“Now, since both of the parents are teachers, and you both go to school there, you all have most likely been exposed. Other families have been able to take custody of the effective kids, but without someone to take custody of you, the government will step in and bring you to one of our facilities.” The man said.

“Were going to be lab rats?” Their mom said, close to tears. Their father tried to comfort her.

“It's gonna be ok, we will all be together and that's all that matters.” He said.

“Don't worry ma’am, you will be perfectly taken care of. No experiments.” The man said. “Now, just to make sure, this device will test to see if you have been affected by the shrink effect. The sonic pulses will go unnoticed by anyone affected, but be extremely nauseating to someone not effected.”

The man put in some fancy electronic earplugs, and held up the disk. He pushed the button and looked around at the family.

Jimmy couldn't hear anything and his heart sank. A part of him knew that he wouldn't, but he still hoped. He looked to his right at his parents and saw they were not reacting either. Suddenly he heard his sister vomit next to him.

“Ew, gross Kat, what the fuck?” Jimmy said shocked by her sudden action.

“Oh, well look at that. Good news everyone. You won't have to come with me. Good thing I brought these other papers.” While the family was looking at Kat in shock and confusion, the man was all business and started handing out stacks of papers to everyone.

“What the fuck was that?” Jimmy asked.

“It seems like your sister doesn't have the shrink effect. You'll be able to stay here. Now sign these papers giving her custody, and she will sign this paper and get $5,000 per month per shrunkee in her custody, every month, per the legal settlement of the federal government vs Carey.” The man explained.

Jimmy's parents seemed relieved at the news. His mother ran off to clean up the mess and hug his sister, while his dad read over the documents and went over the details with the man.

Memories of years of teasing his sister, and their countless fights went through his head. Her gothic look and face full of piercings suddenly looked more sinister.

“But how? How is she not affected?” Jimmy asked.

“Well, sometimes I skip class with Ash and Liz, must have been then. I should text them and see how their test went. But don't worry big brother, I will take very good care of you.” She said, giving him a chilling smile.

The next few days were a nightmare for Jimmy. His parents spent most of their time looking online for tiny clothes and utilities for people affected by the shrink effect. His mother tried to stay up beat, but his father was a bit more reserved. Both were relieved that Kat wasn't going to shrink, but they always had a blind spot for her. They didn't even say anything about the fact that she admitted to skipping school. 


It was the middle of summer, so there was no school to distract him, and he wasn't allowed out of the house in case he shrunk, which could happen at any moment. Getting caught outside at an inch tall would be a death sentence with all the bugs and animals around. 


Kat was happier than he'd ever seen her. She had been on the phone with her two friends, who had skipped school with her and also not going to shrink, and Jimmy overheard her talking about how excited she was. All three of them were talking about people they didn't like in school being tiny, and the other two girls were jealous that Kat was going to be the head of the house. Both of her friends had siblings that were affected, but neither of their parents. 


He was walking out of his room when he ran into Kat wearing tight shorts and a sports bra that barely contained her breasts. She was covered in sweat from a run, and he couldn't help but notice her nipple piercings poking through. 


"Enjoying the view?" She said with a grin. "Maybe we can work out together when you shrink. I'll take you on a run with me. Or maybe I'll let you do pullups on them." 


"Shut up, that's disgusting." Jimmy said as he shoved past her. He could hear her laughing as he walked away. 


In the living room, his parents were opening up some packages. 


"Oh Jimmy, come look at this." His mom said. He walked over and looked at two small cubes, one bigger than the other. 


"These are tiny living cubes for us. This one is yours." She held up the smaller cube, which was about 6 inches cubed. 


His father started pointing out some of the details on it. "it's got a working water system for the bathroom, you fill up the top here, and the waste is collected in the bottom. Not to mention a bed and closet that your mom already picked clothes for." Their father was a bit of a tech nerd and was clearly absorbed in the mechanics of the thing. 


"Wow, that's great." Jimmy said unenthusiastically. He couldn't believe how well they were taking all of this. 


"Look son, I know this is hard for you. It's hard for all of us. But there's nothing we can do about it, so we might as well make the best of it. Just be grateful that we can stay here and not go with the government." His dad said. 


"I don't want to be Kats' pet! She's always such a bitch." Jimmy said. 


"Jimmy! Don't talk about your sister like that. She's going to be taking care of all of us soon. You need to appreciate all the work she's going to put in."


Behind him, Jimmy heard his sister speak up."Don't worry dad, I know Jimmy's just upset that he's gonna be able to fit in my hand soon. I forgive him." He whirled around and saw Kat standing there in a towel, having just gotten out of the shower. She had a smile on, but her eyes were anything but friendly. 


"Ash and Liz are coming over soon." Kat said and went back to her room. 


"If I were you, I'd start being nicer to her." His dad said and went back to looking at their future rooms. 



About an hour later, Jimmy was sitting on the couch watching TV when the doorbell rang. He got up to go answer it and was greeted by Kats' two friends, Ash and Liz. Ash was a skinny girl, flat chested, but with a pretty thick butt. She had bright pink hair, green eyes, and still had braces. Liz was the exact opposite, a bit overweight, but with most of that weight being in her breasts, which were much larger than Kats. She had blond hair and bright blue eyes. 


"Hey Jimmy, I heard the news, so sorry to hear that. But don't worry, well help Kat out taking care of you." Ash said with a gleam in her eye. 


"One of my brothers already shrank, so I already have practice." Liz said with a grin. 


The two girls had been friends with Kat since they were little, and were always around. They had all been on the receiving end of Jimmy's teasing over the years, and had dealt their fair share back at him. 


"Oh good, the neapolitan girls are all here. Kats in her room." Jimmy said and turned around. 


"Oh don't be so cold Jimmy, if you're nice, I'll bring my big sister over to play dolls with you." Ash said giggling. 


Ash's older sister was in Jimmy's grade and was a friend of his. They had hung out over the years and both found mutual interest in bothering their younger siblings. 


The girls walked past him towards Kats room, giggling and flashing smiles at him. 


He imagined what they would look like when he shrunk. Three massive girls looking down at him from far above. Barely as tall as their toes. 


When school started back up in a few months, they would tower over all of their classmates. 

 

He shivered thinking about the near future.

A week later their dad shrunk. 


It happened out of nowhere, one minute he was sitting next to his wife on the couch, the next he was crawling out of his clothes at an inch tall. 


Jimmy was freaked out seeing him so small and knowing that soon he would be the same size. 


His mother thought it was very cute, and couldn't keep her hands off him. He spent a lot of time in the small living spaces they had bought, trying everything out and looking at all the details from his new perspective. The nanobots in his system made him feel like he was half his age again. He could run and jump much farther than he was normally able to (proportionally), and enjoyed climbing around on furniture and his wife. 


Much to his disgust, he had heard his mother making lots of noises in her bedroom with their tiny dad. It was definitely something that would haunt his subconscious for a long time. 


Kat seemed to enjoy seeing her father so small. She stood up straighter when around him, and always smiled as she looked down. She would pick him up and say that she was practicing handling tiny people, but was clearly just doing it for some sort of power trip. She would hold him slightly under her large breasts, and would peer over them at him. They were each as large as a house to him, so the comparison was startling. 


 When they were watching TV, she would place her feet on either side of their father and wiggle them back and forth. At first, their father tried to yell at her to move, but he stopped after her solution was to pick him up with her toes and move him somewhere else. 


Wanting to get away from the reminder that he was going to shrink, Jimmy went outside to swim in their pool. He swam a few laps to help distract him. 


He was able to clear his head with the exercise, until Kat came outside. 


"This'll be like an ocean to you soon." She said tauntingly. “Maybe we can play Jaws when you shrink.”


"Fuck off Kat." Jimmy said. 


"Aww, did I upset you? Don't like the idea of being bite sized?" 


"Just leave me alone." He said and splashed her. 


Kat gasped as the water hit her, soaking her clothes. "You're gonna regret that." She threatened and stormed back inside. 




It wasn't more than a week after that, that their mother shrunk. She was helping her already tiny husband when she suddenly ended up the same size as him. 


Jimmy was now getting nervous. His sister had taken control of their parents, and was basically treating them like pet hamsters. She would drop bits of prepackaged food on the table next to them, and ignore them for most of the day. They were set on the coffee table in front of the TV, so they could jump on the remote and watch whatever they want. 


Every once in a while, Kat would 'play' with them. Jimmy had walked in on her dangling their father upside down and laughing as he flailed around. Their mother was on the table, screaming at her daughter to stop. 


"Hey, knock it off Kat. Put him down." Jimmy ordered. 


Kat looked over at him and smiled. "Oh? Is that you volunteering to be my toy?" 


"You don't own us Kat, you can't just treat us like toys." Jimmy said. 


"Oh, but that's where you're wrong. I do own you. Those papers you signed? They basically say that you are my property the moment you shrink." 


"Bullshit, you better knock it off." Jimmy said. 


Kat stood up and walked over to him and looked up at her taller brother. "Or what?" 


Jimmy shoved her hard and she fell on her butt. "Or I'll do something about it." He said down to her. 


Kat snarled at him and stood up. "Enjoy it while you can. I'm gonna have so much fun when you're tiny." She stormed off to her room and slammed the door. 

 

There was no way he would be able to stay here under his sister's care. He would be tortured to no end. He had to find a way out.

The next day, Jimmy sat in his room, trying to think up options for him to get out. He had to find somewhere else to stay. 


Looking at the small room on his nightstand, he now saw it as a prison. It was hard to imagine that he would soon be able to fit inside it. 


He stood up and started packing around, trying to think. 


"The old lady next door is nice, but she has too many cats. The only ones from school not affected are Kats friends. Who can I call." He mumbled to himself. As he was pacing, he suddenly got dizzy and his vision went black for a moment. 


When he could see again, he was naked and standing on a soft pile of cloth. 


"Oh fuck! No! Not yet!" He shouted. It happened. He had shrunk. He was stuck in his house with his sister. 


He still needed to get out. But this would make things much harder. First, he needed to get clothes. He ran over to his nightstand and looked way up in the air where the tiny living pod was, which had clothes for him. 


He started to climb the leg, and it went much easier than he had thought it would. The nanobots really did give him a boost. 


Soon he was inside his tiny room and pulling clothes out. He picked sweatpants and a T shirt. After he got dressed, he inspected the living space at his new size. It was actually pretty nice. The bed was nice and comfy, and there was a functioning bathroom. 


As he was busy admiring the small room, his door burst open. 


"Hey, I need you to…" his now massive sister said. "where did he go? If he is hiding at someone else's house, I'm gonna be pissed." 


Jimmy dove under his bed to hide. He couldn't let her find him. 


"Heh, he thinks he'll be allowed to stay in his old room? I don't think so." Kats' voice boomed from above. 


Suddenly Jimmy and his room were lifted into the air. Looking out from under the bed, he could see that she was carrying him into her room and dropped on her nightstand. 


"Shit. It's just one thing after another." Jimmy mumbled to herself. 


Kat still hadn't seen him and went about her room oblivious to his presence. Her room was mostly covered in black decorations and emo band posters. She seemed to be tidying up a bit, throwing some dirty clothes into the laundry basket. 


The doorbell rang and she left to go answer it. This was his chance to get out. 


Jimmy quickly ran out of his tiny room and onto her nightstand. Looking down over the edge, he was a bit skeptical on getting down, but he knew staying here wasn't an option. Trusting in his new strength from the nanobots, he lowered himself over the edge and tried to climb down. 


He was about halfway, when he slipped and plummeted towards the ground. Wind rush passed him as he saw his approaching demise. He crashed into the carpet and pain shot through his body. 


But he was alive. The combination of his light weight and his stronger body saved him. He I spected his body, runny his hands over it to check and make sure nothing was broken, and luckily nothing was. 


He stood up and looked around. He was near the edge of her bed, on the opposite side of the room from her bed. He started running towards the door. 


Booms shook the ground, announcing the approach of multiple giants. Jimmy dashed under Kats bed and hid behind one of the legs. 


The door opened and in walked Kat, followed by her two friends, Ash and Liz. 


From his low viewpoint, the sight of the three girls was incredible. They were impossibly large. He was barely taller than their toes. 


"My sister shrank a few days ago, she's so cute now." Ash said. "I've been teasing her about how I finally have bigger boobs than her." 


"Haha yeah, I guess now you're the third bustiest girl in the school." Kat laughed. 


"But I'm still too flat to keep her in my cleavage, since I don't have any. I'm jealous of you two." Ash said dejectedly. “But at least I got this big ol’ booty.” She said slapping her butt. 


"I told Jimmy that I was gonna stick him in my boobs when I go for a run, or make him do pullups on my nip piercings." Kat said laughing. 


"It's so funny using these to intimidate all my tiny brothers. I like leaning over them and having my tits dangle over them. Their faces are so funny." Liz said. 


"You could probably fit half the school in your bra Liz!" Ash said. 


"I would love to get my hands on those cheerleader bitches from school and stuff them down there. Make them regret calling me fat." Liz said. 


"I can't wait for school again, it's gonna be so cool being so much bigger than everyone. I heard they're gonna bring in substitutes to teach since all the teachers are tiny." Kat said. 


"Oh, your parents aren't gonna teach anymore?" Ash asked. 


"Nope, they'll be staying home while Jimmy and I am at school." Kat replied. 


"I'm excited to see your brother tiny. It's gonna be so much fun to play with him. I want to put him and my sister in a dollhouse and play with them." Ash said. 


"I'm excited too, but I'm not gonna be so nice to him. I have a lot of payback to dish out." Kat said. 


"You're not actually gonna hurt him, are you?" Liz asked. 


"Nah, nothing permanent. He's my meal ticket after all. I won't get my handouts from the government without him." Kat said laughing. 


"I think my sister is too cute to be mean to. I just like teasing her and playing with her." Ash said. 


"Well I haven't even seen my brother since yesterday. I think he might have ran away." Kat said. 


"What? Are you sure?" Liz asked. "Where would he go?"


"I don't know, but he wasn't in his room this morning." Kat said. 


"Are you sure he didn't shrink?" Liz asked. 


Kat sat up straighter, "God I'm stupid. That's probably it!" 


She stood up and walked towards her door, "fee fi fo fum, I'm coming for you little bro." She said as she stomped towards his room to look for him. 


A few moments later, the other two girls sighed and got up to go help her search. 


Seeing an opportunity to get out, he made his way towards the door. He didn't want to get caught out in the open, so he ran along the side of the walls. 


At normal size, it was only a few steps, but at his new size, it was an incredibly long journey. 


As he passed her closet, he saw dirty clothes hanging out of her laundry basket, and assorted massive things like her purse. 


Everything seems to make him feel smaller and smaller. Her sock was several times larger than his entire body, he could get stuck in just the toe section. Her bra was incredibly large. Each cup was like a house to him. He shook his head, trying to dismiss the thoughts of how large the breasts that filled that bra are. 


He had wasted too much time distracted by the sights, and thundering footsteps started to approach. 


Needing a place to hide, he quickly dashed to her nearby purse and jumped inside. 


"Well, he's either at someone else's house, or hiding. And if he's hiding, he'll have to come out eventually to eat." Kat said. 


"Well, I'm sure you'll get him soon. Are you ready to go to the mall?" Liz said. 


"Sure, let me grab my purse and we can go." Kat said. 


Jimmy panicked, and thought about jumping out, but there was no way he could escape being seen if he did. 

 

The purse was lifted into the air and Jimmy was thrown about among all the junk in there.

Jimmy could tell that the mall wasn't as crowded as usual, but still had plenty of people from the noise. He could hear the muffled voices of the three girls as they walked around the mall. 


Jimmy was too busy dodging all the stuff in Kats purse as it bounced around to pay attention to what they were saying. After what seemed like an hour, gravity suddenly shifted and the purse was dropped into the ground and fell on its side. 


Carefully crawling towards the opening, he peeked outside. He was in a store changing room. Above him, he watched as Kats towering form pulled her shirt off and her huge breasts bounced around in a black lace bra. 


He couldn't help but have a reaction from the sight, but quickly looked away to find a way to escape. 


There was a large gap under the walls of the changing room, but making a dash straight across to the door would surely get him caught. So he dashed out along the wall to the left to cross under the wall into another room. 


When he entered, he looked up at it's occupant. It was a nearly naked woman with a slight belly, but incredibly large tits. So big they made Kats look small. He was mesmerized by the gentle bounce and sway of them. 


After a moment he was able to tear his eyes away and look further up to her face. It was Liz! 


"Damn Liz, I knew you were stacked, but this is incredible." He mumbled to himself. 


Knowing that this exit was blocked too, he decided to go back and try the room on the other side of Kat. 


As he ran along the wall, he did his best to resist looking at her massive, plump ass while she was bent over taking her pants off, revealing a black thong. 


When he got to the other room, he saw that Ash was changing. She was topless, and while her breasts were larger than his entire body at the moment, after the last two girls, he was shocked by the sight. 


Until she turned around. 


Her thighs were thick and her ass was huge. Each step she took sent ripples through it. She also wore a thong, which was easily swallowed up by her cheeks. 


With this path blocked, he was forced to turn back. He made his way along the wall, resigned to having to hide in the purse again and hope for another chance. 


Suddenly, his world went black and he was covered in some sort of fabric. Kat must have tossed some article of clothes on the ground and it landed on him. 


He tried to find his way out of it, but quickly got tangled in it. It was a thin material, with lots of weird designs and tiny holes that would be see through normally, but at his size, large enough for his limbs to get caught. 


Not wanting to make alot of noise or movement and alert her, he quietly tried to free himself, but made little progress. 


After a few minutes, his cloth prison lifted into the air, and took him with it. 


It took all his will power to not scream out as he suddenly rushed into the air. 


Unfortunately, this seemed to help free him, as he slowly slipped out of the tiny holes his limbs were trapped in. Quickly, he grabbed onto it as tightly as he could to prevent himself from tumbling to the ground. 


Kat seemed to be moving the article of clothing alot, as it kept bouncing around. He looked up and luckily saw her chin as she did this without looking down. 


Too late, he looked behind him and saw her massive pierced nipple quickly approaching. 


"Oh fuck" he said under his breath as he realized he was in her bra. 


The giant nipple collided with his back, and the metal studs poked into his sides. He was squeezed tight against it as she hooked her bra on and put her tight shirt on over it. 


Jimmy knew he was in a very dangerous position. Her nipple was a very sensitive spot, and any movement could alert her to his presence. He couldn't imagine what she would do if he was found like this. 


He held as still as possible as she started walking around. Which was very hard to do. She was a big titty girl, and big tittys bounce. Alot. 


As he was thrown around, he could hear the girls talking about getting food. A moment later he could smell the strong aroma of the food court. 


After ordering food, they sat down to eat, and thankfully stopped walking, allowing Jimmy to rest from all the bouncing. 


"Want to come over tomorrow and swim?" Kat said. 


"Sure" Liz replied. 


"Can Amy come? I got her a tiny bikini top! It's so cute." Ash said. 


"Haha sure, hopefully Jimmy will turn up by then. I'll have to leave a trap out for him like a little mouse. He's gotta be getting hungry." Kat said. 


"Isn't it crazy how they're all smaller than these fries?" Liz said. "my 3 big older brothers are all so tiny now." 


"I know, isn't it great?" Kat said. "Its such a thrill standing over these tiny people."


"Yeah, it's been fun for me. I think they're all so cute." Ash said. 


"I dunno, I do like being in charge of my brothers for a change, but I do feel a bit bad." Liz responded. 


"I don't. I love it. I can't wait to get my hands on more of them. Thinking about all the kids in school fitting in my hands turns me on." Kat said. 


On cue, Jimmy felt pressure on his back as her nipple stiffened. 


"Really? Is that like a fetish thing?" Liz asked. 


"Yeah, I looked into the shrinking effect back when it first happened to someone and I went down a rabbit hole. Imagine what we look like to them. We're basically goddesses." Kat said. 


"That's true, we can pretty much do whatever we want to them." Ash said with a giggle. 


"And just think about all the places they can fit." Kat whispered loudly to them. 


"Oh, you're bad Kat." Liz said after a laugh. 


After a few more minutes, they finished eating and grabbed their things to head home. 


Jimmy was thrown around as Kats breasts bounced with each step. Once they got in the car, it was much easier for him, except for the occasional bump in the road. Kat was driving, and dropped off both of her friends before heading home. 


"Jimmy! Are you back?" She yelled after getting home. After receiving no response, she added "where the fuck is he? Whatever, I'm going to take a shower."


Jimmy stayed silent and still, knowing that he would have to be very careful in order to escape his titty prison when she undressed. 


When she got to the bathroom, she pulled her shirt above her head, causing her boobs, and Jimmy to bounce around in her bra. With her shirt gone, he could see through the bra fabric and could see her reflection in the mirror. Her large breasts were accentuated by her skinny waste, and wide hips. 


Her bra was next to come off, Jimmy had to hide in it and sneak out after she got into the shower. 


He felt as the fabric loosened and started to pull away. Gravity started to pull him down with the bra, until he was suddenly stopped. 


Twisting around to see what he was stuck on, he saw his shirt was hooked onto her nipple piercing. He was dangling by it, now fully exposed. 


"Oh fuck" he said. He looked into the mirror and saw Kats wide eyes were locked into him. 

 

"Oh my God." She said, with her plump lips forming a smirk. "Well what do we have here?"

Author's Notes:

A bit of a shorter chapter, Ive been pretty busy in the real world, hopefully I can find more time to get back to writing. Please comment and let me know what you think, and feel free to make suggestions for future chapters.


Kat put her hands on her hips and started slowly shaking her large breasts side to side as she laughed at her brothers predicament. 


"Seems like a tiny pervert found his way into my bra." Kat said. "Do you like my big, big boobies?"


Jimmy could feel her nipple harden as he was shaken back and forth by her bouncing boobs. 


"No! It was an accident! I got stuck in your bra at the changing room!" He tried to explain. 


"You were watching me change? You really are a little pervert." She said. "Your so tiny and weak, my nipple is bigger than you." Kat grabbed her other breast and started massaging her nipple as she bit her lip. 


"I must be like a living goddess to you now. So powerful and sexy." She said.



Kat stepped into the shower and turned on the water, Jimmy still dangling from her nipple. 


"Kat! What are you doing? Get me off of here!" Jimmy yelled. 


"I don't think so little toy, your goddess wants to play." She said as she began to pour liquid soap on her body. 


She plucked Jimmy off her nipple and began using his tiny body as a loofa, rubbing him all over. 


The soap covered his body, as he was rubbed all around her breasts, around her stomach, and on each plump ass cheek. Her soft skin made the entire experience more mentally uncomfortable than painful. His sadistic sister was truly enjoying having so much power over him. 


After a few minutes she held him up under the shower stream, rinsing him off. He looked at her face and saw her large grin and eyes filled with desire. 


"You look so cute at that size, I could just eat you up." She said. "In fact…." Her mouth opened and she stuck out her pierced tongue. 


"No! Please don't eat me!" Jimmy yelled in panic. 


Ignoring him, she dropped him on her tongue and sucked him into her mouth. 


He grabbed her piercing to stop her from swallowing him, but it was like riding a wet, wild bull. He was thrown around her mouth and covered in saliva. If it wasn't for the nano bots making him more resilient, he'd surely be a broken and bruised mess. 


The rumbling coming from deep in her throat let Jimmy know that Kat was laughing at his predicament. After what seemed like an hour, her mouth opened and light flooded in. 


Her massive fingers reached for him and plucked him out. She was grinning madly at him. 


"Look what I grabbed while you were having fun in my mouth" she said holding up a big purple dildo and some rubber bands. "Having so much power over tiny people has been my fantasy for a while, and I'm going to enjoy every minute of it."


"Kat! I'm your brother! You can't do this!" Jimmy yelled. 


Kat laughed at his pleas. "We aren't even the same species anymore, little bug." With that, she ties Jimmy to the dildo with rubber bands, trapping him in place. 


Jimmy struggled and screamed to no avail as he was lowered to Kats massive pussy. She slowly thrust him deep inside her, covering him in her juices. The soft walls of her insides pressing against him. After he went in as far as she could get, things got much more violent. She started to rapidly thrust him in and out, as fast as she could. He could hear her moans whenever he was pulled out, and she was clearly enjoying herself. 


It wasn't long before he could feel her insides tighten and pulse with pleasure, and Kat let out a much louder moan. She stop thrusting him and slowly pulled him out. Kat held him in front of her face and laughed at Jimmy's exhausted looking form. 


"Was it good for you too?" She asked sarcastically. She quickly finished rinsing off in the shower and got out and walked to her room. 


Jimmy couldn't believe what had just happened. Kat had just made it very clear that he was not even a person to her anymore, and just a plaything. They had never really gotten along, but this was too far. He needed to figure out a way to escape. 


Jimmy was dropped into her bed as she changed into her night clothes, a thin nightshirt and tight short shorts. She also pulled out a single sock. 


"This is another thing I've been wanting to try out. You're gonna be spending a lot more time where you belong, under my feet." Kat said, waving the sock around. 


Jimmy got up and tried to run towards the edge of her bed to try and escape under it, but his exhausted body could barely move and he was quickly snatched up. 


"I don't think so. Now be a good pet and make sure to wiggle a lot." She said as she dumped him in her sock. She sat down and slowly slid her small (to her) foot into the sock, wiggling her toes in expectation. 


Jimmy watched as the 5 massive toes made their way to him. There was no place for him to escape, and they quickly wrapped around him. The still slightly wet toes scrunched over his body repeatedly as he struggled to get out from under them, but they would let him go. Despite just taking a shower, he could smell a ripe stench from them. 


Kat layed down on her bed, still glowing from her shower "massage" and giggled to herself as she wiggled her toes. 

 

"This is a dream come true. I can't wait till school starts up again. Looking down on a school full of tiny bugs is gonna be so fucking hot." Kat said to herself, imaging all her old schoolmates in the palm of her hand.
