“No fucking way mom! That’s not happening, you can’t do that! You just can’t!” Kevin shouted up at his mom in disarray.

 

“Oh, I think you’ll find that it is happening, and I can do that.” She said to the little man who remained dangling between her fingers.

 

Kevin couldn’t believe his ears. Surely this was a nightmare. Was he dreaming? Sadly, for Kevin, this was very much real.

 

“Mom, please…”

 

“I don’t want to hear it Kevin, my minds made up. You should have absolutely no complaints after the things you’ve been up to this weekend!” Amanda said back, firmly.

 

“H-how long are you gonna keep me like this for?”  Kevin asked. He wasn’t sure if he truly wanted to know the answer to that.

 

“Oh, I don’t know, days possibly… but possibly weeks. To be honest Kevin, with the way you’re going, it might get to the point where you don’t actually want to be grown back. You seem to be enjoying yourself enough!”

 

“Mom, don’t say that!” Kevin shouted up towards her.

 

“Hey little guy! It’s not my fault that you decided to be a perv to your sister, and then proceed to get hard whilst underneath my feet!”

 

Off the back of that last comment, Kevin fell silent. He dangled there, feeling completely defeated. He knew there was nothing that he could say back to this. 

 

Ari stayed silent throughout this whole ordeal. She was still sat on the couch, just observing the conversation that her brother and her mom had. A part of her did feel bad for Kevin, staying small for who knows how long really isn’t gonna be fun for him at times. A less sympathetic part of her couldn’t help but think. “Oh, this is going to be fun. This is going to be really fun!”

 

“Well, who’s gonna look after me during the day?” Kevin asked. “You have work and Ari has school. You can’t just leave me here alone.”

 

“Ummm… I guess me and Ari will take turns. Some days you’ll go to school with her, some days you’ll come to work with me.” Amanda replied.

 

Oh, this was definitely something Kevin didn’t like. He couldn’t think of anything worse than going to school with Ari and potentially being at the mercy of a bunch of 18-year-olds.

 

As if to read her tiny sons mind and want to inflict more mental torture upon him, Amanda said, “you’ll go to school with Ari tomorrow. Is that alright Ari, honey?” 

 

A grin formed on Ari’s face over on the couch. 

 

“Yeah mom, that’s all good with me.” Ari said, trying to hide her satisfaction with that decision.

 

Kevin decided not to say anything this time. No matter what his response was, it seemed his mom would always come out victorious.

 

“Well, that’s settled then!” Amanda said with a smile. “Now… I don’t know about you Ari, but I could really spend a-few hours watching some TV on the couch.” She continued. “Now, where is the best place to put Kevin, I wonder?” She sarcastically as scratched her head and chuckled. 

 

Amanda went and joined her daughter on the couch.

 

Amanda placed Kevin down on the coffee table that was positioned in front of the couch. Kevin knew what to expect. He looked up and saw 2 giant feet coming towards him and stopping right in front of his face. Kevin was in no mood for this. He just wanted the ground to swallow him whole.

 

Soon enough, Ari’s feet accompanied her mom's on the coffee table. They shared a chuckle as they sat back to watch TV, both also watching the tiny little Kevin down at their feet.

 

This was how Kevin would spend his night, getting completely smothered in the 2 beautiful giantess's feet as they rolled the little man around underneath their soles.

 

 

 

The next morning, Kevin awoke to a voice outside of his wooden box. Kevin’s box last night had once again been left on the kitchen countertop overnight. 

 

“Ohh Kevin.” He heard his sisters voice say from outside. “Time to get ready little man, we’re leaving for school soon!”

 

Stilly groggy from his sleep, Kevin managed to pull himself out of bed. He was dreading the day ahead of him. Going back to his old high school was bad enough, but doing it in the clutches of his little sister was even worse. 

 

“Ouch.” Kevin said, feeling the small injection on his arm. His mom had injected him with some more of the vaccine last night after ScienceCorp delivered the extra doses. This ensured he would stay small for 3 more days and then she’d have to inject him again.


After mustering the strength to get ready, Kevin opened the door to his wooden box. He stepped out onto the kitchen countertop and looked up. Ari had been waiting for him outside the box. She was wearing some nice light blue jeans that did wonders for her already incredible ass. She was also wearing a pretty white crop, which was exposing her tanned, athletic stomach and her cute belly button piercing. Another result of the crop top was of course, the fact her amazing cleavage was on full display. She was wearing her hair in a nice cute high ponytail.

 

“How the fuck do boys at her school even go about their day normally when that’s in front of them?” Kevin thought to himself as he observed his gorgeous sister.

 

“Um, my eyes are up here!” Ari said down to her tiny brother with a chuckle, noticing him marvelling at her breasts.

 

Kevin snapped out of it. “Sorry, sorry.”

 

“And yes, I know what you're thinking.” She said, as if to read Kevin’s mind. “Yes, I’m gonna put a sweatshirt on. It’s impossible to have boobs at high school without feeling like every single boy’s eyes are on you.” Ari joked. She squeezed her boobs together lightly as she spoke, just to emphasise her point. 

 

Kevin couldn’t help but blush as he saw even more of a cleavage form at her chest.

 

“Okay, I’m heading out to work guys. I’ll be back at around 6PM.” Amanda said as she entered the kitchen to grab her bag.

 

Amanda was dressed in a smart black dress and some black heels. Although she was dressed formally, my god did she look good. Her huge ass was looking as gorgeous as ever. 

 

Amanda directed her attention to Kevin and plucked him up from his spot on the table.

 

“You better be on your very best behaviour, little guy!” She said sternly down towards her son. “Ari will tell me if you’re not! Try and have a good day Kev, and please don’t get lost.”

 

“Okay mom” Kevin replied in a depleted manner. “I’ll try not too…”

 

Amanda then dropped Kevin over into the palm of Ari’s hand.

 

“Make sure you keep an eye on him at all times, honey.” Amanda said. 

 

“Don’t worry, mom I definitely will.” Ari replied reassuringly. “This little guy isn’t getting out my sight!”

 

With that, Amanda gave her daughter a kiss on the forehead before making way towards the door, her heels making a clicking sound with every step.

 

Ari looked down towards Kevin in her hand before speaking.

 

“Okay little man, I wonder where I should keep you whilst I’m at school. The only pockets I have are in my jeans, but that’ll be way too tight and might suffocate you. I can’t keep you in my bag because I have all sorts of things in there; it’ll be way too dangerous for you…”

 

Oh god, Kevin hadn’t thought about that yet. Of course, Ari couldn’t just carry him around all day in her hand, she’d have to find somewhere to keep him. This could be trouble…

 

Ari bit on her long pink painted fingernail as she thought. A slight smile was apparent on her face.

 

“Hmm… I suppose I could keep you in my shoe…” she said down to Kevin.

 

Kevin did not like this idea one bit. He’d had enough of feet, especially after everything that had happened yesterday. Ari could see the dismay on Kevin’s face at the idea of this. She let out a small giggle at the sight of it. It almost made her want to put him in her shoe for the day even more.

 

“But I guess that’s not very practical. I’m pretty sure at your little size my powerful foot would crush you pretty easily. Wouldn’t that be a pathetic way to go huh, Kev? Crushed under your little sister's massive sweaty toes…” She said with another giggle, once again entertained by the little man’s reaction to this. “Hmm… you know what, I think I have an idea. I think you’ll like it.”

 

With that, Ari plucked the little man up and hovered him above her outstanding cleavage. Looking down towards him as he hovered just above her mountain like boobs, she spoke.

 

“Yeah, I think this is going to be the best place for you today. It should be nice and soft, and you seemed to enjoy the last time so much…”

 

Kevin looked directly down below him. My god it was an impressive sight. Once again, Ari’s huge breasts were making him feel like a tiny little bug. They were inanely beautiful, and they came together to form an even more impressive cleavage, the cleavage in which Kevin would be spending most of his day in. He definitely wasn’t particularly mad at this.

 

“Oh- okay that’s fine I guess Ari…” Kevin said. Between this and her shoe, he would take this every time.

 

Ari saw her little brother was clearly pleased with this decision. Of course he was, why would he not be? She wanted to tease him just a tiny bit more.

 

“Hmm I don’t know Kev, on second thought my shoe might be a little bit better. I mean, I don’t want you to be jacking off down in my cleavage all day, that could get messy.”

 

Kevin panicked. “No, Ari come on. Please I promise I wo…” 

 

He was cut off by her laughing, she was extremely entertained with how panicked Kevin was.

 

“I’m kidding! God come on Kevin my feet aren’t that bad… I would have thought you definitely wouldn’t mind spending the day at them after your antics yesterday on the couch…” she said to him as she suggestively raised her eyebrows.

 

Kevin blushed, thinking back to how he’d basically worshipped his sister's feet the day before. He could almost still taste that foot sweat of hers in his mouth.

 

“Anyway, we need to go or we’re gonna be late.” Ari said. “You better behave yourself in there little man…” Ari said to him.

 

With that, Ari released her tiny older brother as he sailed down towards her fleshy mounds. Ari looked down towards her breasts in amusement as she saw his tiny little head barely poking out. She gave her boobs a quick squeeze together. She wanted to emphasise the sheer power of her breasts to Kevin. 

 

With a giggle, Ari put on her grey sweater and left the house, her boobs jiggling up and down with every step.

 

 

 

 

Amanda walked into the office as her heels continued to clack away. She greeted her colleagues as she walked through the building towards her desk. Lots of her male colleagues caught a quick glance at that amazing ass as she walked past them. Lots of the men often marvelled at Amanda’s beauty, she was certainly a pleasant sight to see at the start of the week on a Monday morning.

 

Amanda finally reached her desk and took a seat. She took just a moment to sigh and gather her thoughts after a stressful weekend. “Hey, girl!” Amanda heard from the desk next to her. 

 

The words had come from her co-worker and friend Zoe, who she had formed a friendship with after working beside her for so long.

 

“Are you okay? How was your weekend?” Zoe asked asked Amanda. She could clearly see something was on her mind.

 

Zoe was another one of the offices gorgeous women. She had a nice mixed-raced skin color and nice brown curly hair. She also had some amazing green eyes that complimented her other facial attributes beautifully. Similar to Amanda, Zoe was also a fairly busty woman. 

 

“Where do I even begin?” Amanda said back to Zoe as the other woman gave her a slightly concerned look.

 

“What’s wrong?” Zoe asked Amanda before quickly remembering her situation. “Oh crap! Kevin shrunk this weekend, didn’t he?! So… it didn’t go too well?”

 

“I guess you could say that…” Amanda began. “If I tell you the truth, do you promise me you won’t judge me at all?” 

 

“Of course, girl!” Zoe replied back. “You know that got you! There will be no judgment whatsoever.” 

 

Amanda then spent the next 10 minutes or so explaining everything to Zoe. She explained how she had found Kevin and Ari having some “fun” that night that she’d found Kevin playing on her daughter's breasts. She explained how Kevin had gotten turned on whilst rubbing her feet, and she finally explained how because of all of this, Kevin was going to stay shrunk for the foreseeable future.

 

“And I just don’t know where I’m at right now…” Amanda rambled on. “Of course, I love Kevin. Even if he’s been a tiny little pervert, he’s still my son! I just don’t know where this puts us as a family right now…”

 

Zoe continued to listen with extreme engagement. She was eager to help her friend who was clearly stressed out at the situation.

 

“Amanda, listen…” she began. “You know that it’s not uncommon for family dynamics to severely change once a male in the family takes their vaccine, right?” She reassured her friend. “It happens all the time. Sometimes when men shrink down… they just can’t help themselves. For some men they eventually realise that maybe being tiny is all they’ve ever really wanted, and it goes both ways as well. Sometimes moms and wives and girlfriends realise maybe it’s best to keep their man this way, for both of their happiness.”

 

“What are you saying?” Amanda asked back to Zoe curiously, trying to read in between the lines.

 

“I guess what I’m saying is… you don’t know when to let Kevin grow back or how to fix things in your family, right? Well, what if over the next few days, you both realise that this is how things should be now.” Zoe replied. “It sounds like Kevin’s having a good enough time himself, and from what I’ve heard, you're certainly enjoying having all this power over him too.”

 

Amanda pondered over what Zoe had just said. She had to admit, it was good advice.

 

“So… you're saying that this could be a good thing and that I should just relax and go with the flow for the rest of the week?” Amanda asked back.

 

“Yeah, pretty much.” Zoe replied. “I think by the end of the week you might have a better idea about what you want to do and what’s best. Take Liz for example, look what happened with her and her husband.”

 

Both of them glanced over to their co-worker liz, who worked at a desk slightly further away from them. Liz was another attractive woman in the office. She had long blonde hair and was sat with her right leg crossed over her left on her chair. Her open toe high heel was bouncing up and down.

 

Liz’ husband had shrunk around a month ago. Liz had been rather pleased to have a-few days where she could keep a close eye on him, as he had somewhat of a wondering eye, often caught looking at other attractive woman and talking to girls in a slightly more friendly way then Liz would have liked him too.

 

Liz’ husband had shrunk during the working week, and with no one to look after him she had to take him into the office with her for those 3 days. Co-workers of Liz could often hear them squabbling throughout the day for whatever reason, lots of the time it was about how he looked at some of her giant female co-workers. These squabbles would often end up in Liz getting fed up and giving herself a minute to cool off by leaving him inside her handbag for an hour or so.

 

As the 3 days went by, Liz decided that she actually preferred having her husband as a tiny man and wanted to keep him this way. This way she could always keep an eye on him and make sure he was behaving himself. After ScienceCorp had agreed to giving her more vaccines, she decided she was going to keep him small for the foreseeable future. 

 

Now, Liz’ husband comes to work with her most days, and often spends most of his time underfoot in her high heels whilst she works. Whether or not he liked it, it certainly made her happier. Liz often now flirts with her male co-workers, giving her husband a taste of his medicine as he has no choice but to listen to other men hitting on his wife whilst he gets a face full of her foot, trapped beneath her sole with nothing he can do about it.

 

“Yeah… maybe you’re right.” Amanda replied back deep in thought as she looked at Liz. She was sure she could see a tiny little man under her sole as her foot bobbed up and down.

 

“And one more thing. Just try not to be too harsh on him. There’s a way you, him and Ari can all enjoy his situation, it doesn’t have to be done in a malicious way.” 

 

Amanda continued to think about these words that Zoe had said. Still deep in thought, her eyes stayed fixated on Liz’ high heel, bobbing up and down, up and down…

 

 

 

 

Ari arrived at the campus of her school with a spring in her step. She kind of enjoyed school, she was really popular and had loads of friends. Being as attractive as she was, she was also really popular with the boys.

 

The walk to school luckily wasn’t too far for Ari at all. They lived just 20 minutes away from campus.

 

For Kevin, the walk had been an interesting one. Ari’s breasts were giving him a warm hug as the wrapped around him. He had to admit, he was enjoying it as her mounds continued to engulf him, wrapping around his body with the slightest movement from Ari. It had also been a bouncy 20 minutes for Kevin, as Ari’s boobs bounced up and down with lots of force as she walked, taking him for the ride with them.

 

Ari walked through the halls towards the classroom for her first period. As she walked along, she saw lots of friends and classmates. Out the corner of her eye, she spotted a familiar face stood by the lockers. She saw Cody, clearly flirting as he chatted away to one of the many girls he talks to on a daily basis.

 

“Ugh, what an asshole!” Ari thought to herself. Her and Cody had stopped seeing each other a couple of weeks ago, and it’s safe to say he managed to move on pretty quickly “I should have stomped on his tiny little ass when I had the chance!” Ari chuckled to herself, thinking back to those few days that Cody had shrunk. “I wonder how his friends would react if they knew he’d been massaging his dad's feet for 3 days!”

 

Entering her classroom, she took a seat, only slightly still agitated from what she had seen Cody doing.

 

Although Kevin was nice and comfy perched between his sister's beautiful tits, he was still pissed off about the whole situation. “This is just so humiliating!” He thought to himself. “I’m 20 years old! I should be able to do whatever I want, but here I am being forced to go to school with my little sister!” He raged silently again.

 

Kevin felt extremely degraded. Why was it that his sister got to live her normal life and go about her day with free will whilst he was being treated like a little pet? It just wasn’t fair. Kevin felt extremely trapped. He was completely unable to move as Ari’s cleavage held him there. He wriggled to try and get his arms free.

 

As Ari sat down above as her teacher started talking. She could feel the little man trying to wriggle free from in between her cleavage. This made her giggle. Why was he even trying? “Give it a rest, Kev” she thought to herself. “I’m just so much bigger and stronger, there’s no point trying.” She smiled with this thought.

 

She subtly pushed her arms against either side of her breasts, pushing them together. She wanted this to once again emphasise to Kevin that he was absolutely helpless. One squish of her boobs and it would shake his whole world up.

 

Down below Kevin felt exactly that as his sisters boobs completely covered his whole body. Maybe this was just what he was meant to be now, a little bug of a pet for his mom and sister…

 

 

 

 

Kevin had remained in Ari’s cleavage until her lunch break. Throughout the day he’d often felt his sister give that squeeze of her boobs. She wanted it to serve a reminder to him that there’s no point in resisting it trying to wiggle, and that he’s completely at her mercy.

 

Ari had spent most of her lunch break with her friends, 2 of them being Mia and Rosie who she’d been at the mall with a couple of days prior. Towards the end of the lunch break, Ari had asked to talk to Mia in private. Of course, Mia knew everything that had happened between Ari and Kevin, but she didn’t know he was still tiny. They went to a quiet part of campus where no one was around.

 

“Okay Ari, what is it you want to tell me?” Mia asked her best friend, slightly concerned. “Girl, I swear to God if this is about Cody again, I’m gonna kill you! You just need to let that boy go!”

 

“No, no relax it’s not about Cody.” Ari reassured her friend. “Just look…” she said, reaching down her sweater into her cleavage to search for the little man. 

 

Mia watched on curiously. She was really confused about what Ari was doing. She continued to watch as Ari’s hand came back up above from her chest and out came… a tiny little Kevin. Ari held him in front of Mia.

 

“Oh my god!” Mia said in surprise. “Is that… your brother?!” She continued “Wasn’t he meant to grow back already?” 

 

“Yeah, he was. But remember that conversation we had yesterday? About how my mom had caught me and Kevin having some, you know… fun. Well, my mom decided it would be best to keep him small for a while…”

 

A shocked expression remained on Mia’s face.

 

“So, you’ve been keeping him in between your boobs all day?” She asked. “That is fucking hilarious!”

 

Kevin lay there in Ari’s hand as he looked up at the two beautiful girls faces. They were looking down at him like he was a prized possession. There was an especially hungry look in Mia’s eyes as she looked down towards him, a look that made the tiny man feel slightly vulnerable.

 

“Oh my god!” Mia chuckled. “No fucking way! So, you and your mom are just gonna keep him like this for a while?”

 

“Yep!” Ari said proudly. “He’s going to be our little man for the foreseeable future.”

 

Kevin cringed as he heard his sister say this, feeling extremely embarrassed. He was sick to death of being referred to as “little man”.

 

“You are so lucky!” Mia replied back. “God, I wish my mom had kept my brother small…” she said, still looking down at Kevin with that same hungry look. “Can I… can I touch him?” Mia asked.

 

Ari nodded in reply before Mia plucked him up off of her friend's hand. She raised the tiny man up to her face.

 

“Hey there, little Kev” she said with a smile, holding Kevin up very close to her pretty face. “Oh my god! he’s so cute! And somehow, he’s even hotter at this size!” she laughed. “Oh, I could just eat you up little man!”

 

As she said that last part, Mia raised Kevin up above her mouth and opened wide just to demonstrate what she had said. Kevin looked down into her mouth. It was gaping, one drop and he would be a goner.

 

Mia took a moment to just think about how fun it would be to drop the tiny Kevin into her mouth. She thought about him rolling around inside of her mouth, getting pushed around by her powerful tongue whilst getting completely covered by her saliva. 

 

She giggled as she thought about how his tiny little dick would get brushed as he rolled about, and how the sheer power of her tongue would probably be too much for him to handle, causing him to ejaculate his tiny little loads everywhere as she swallowed him, and he fell towards his peril.

 

“Okay… that’s enough.” Ari said as she took her brother back from Mia and held him in her hand for a moment. “Damn, Mia, I actually thought you were gonna eat him. For a second!” She laughed.

 

“Give me 30 more seconds and I will!” Mia laughed back. This definitely disturbed Kevin as he heard it from down in Ari’s hand.

 

Ari gave her phone a quick look so she could check the time. It was 5 minutes until their lunch break ended.

 

As she put her phone back in her pocket, Ari grinned as she remembered what class she had next.

 

P.E

 

This was going to be fun…

 

 

 

Ari walked out of the female locker room and into the bathroom after getting changed for P.E. She was now wearing her schools P.E shirt, as well as some tight Nike pro shorts. As usual, those Nike pro shorts were complimenting her huge ass incredibly. They just made her ass look even more huge and displayed her thick tan thighs and legs. Ari often caught some of the guys staring at her during past P.E classes. She didn’t particularly love all the attention, but how could she blame them for looking.

 

Ari reached into her bra cup and fished Kevin out. She’d had to keep him in her bra cup whilst she changed as some of the other girls would have definitely seen him If she’d kept him in her cleavage.

 

Ari’s bra cup had been an interesting experience for Kevin. Once Ari had placed him inside, he was directly met with her nipple. The fabric of her bra pushed into his back as Ari’s huge breasts completely filled up her double D cup. This pressed his face right into her hard nipple. Kevin tried hard not to think about what had happened a couple of days prior involving him and Ari’s nipple. He was trying his absolute hardest to keep his mouth away from the nipple that had tasted so good a-few days prior.

 

Ari held him in her hand and spoke down to the little man.

 

“Okay Kev, you know what, you’ve behaved well today, so I’m gonna give you a little treat.”

 

“W-what is it?” Kevin asked back, slightly worried. He was worried because it had seemed whilst he was this size, the word “treat” meant different things for him and his family.

 

“Oh, Kev come on, stop looking so worried.” She said down to him. “What you’re about to experience is something hundreds of guys would kill for! You should be grateful!”

 

“Okay okay, what is it then?” Kevin asked her, eager to know what was going to happen to him. She did have a point. Kevin knew that hundreds of boys would pay good money to be tiny in Ari’s clutches for even a day.

 

Ari smiled a mischievous grin at him. She went into a cubicle and placed Kevin on the ground for a moment.

 

Kevin stared up at Ari as she began to take her shorts down. Once again, he could only marvel up at her as he watched her fleshy ass overflow her tight shorts. As she pulled her shorts down lower, that amazing butt came cascading out, jiggling as it fell. Finally, she got her ass all the way out, revealing that beautifully shaped thonged butt of hers. Kevin looked up in awe. Her ass looked like an actual planet above his head right now.

 

Ari bent down and picked Kevin back up. Without warning, she began to move him towards that great butt of hers. Ari held him there in front of her ass for a moment. She wanted to him truly appreciate how amazing it was, and she wanted him to truly appreciate how much of a goddess she was.

 

Kevin could do nothing as he came face to face with the gorgeous butt. He stared for a moment. It was so huge, so smooth, so perfectly shaped. 

 

“Just take it in for a moment, Kev.” Ari said from up above. “I know you like it. How could you not?”

 

Ari did a small little jump. As she landed, her whole ass jiggled right in front of his eyes. Kevin and been with some pretty hot girls before, but nothing could ever compare to what he was seeing.

 

He then found himself moving closer to the huge ass. Ari moved him closer, and closer, and closer. She wanted to tease him as much as possible, so she moved him very slowly.

 

Finally, he reached the crevice of her butt cheeks. He felt himself enter them as Ari stuffed the little man inside of her butt. He was absolutely swallowed by her huge cheeks.

 

He lay there inside her ass. It was so very soft, so very plump. he felt her huge cheeks pressing against either side of him, trapping him inside this fleshy prison.

 

Ari pulled her shorts back over her ass, completely sealing Kevin inside her ass. It was very amusing to her how she could just trap her brother inside her body with no effort.

 

Once again, she felt completely powerful.

 

 

 

 

Ari stepped inside the school gym followed by other students. This P.E class the students were told they would get to spend the hour doing their own workouts in the gym. This was perfect for Ari.

 

With every step that Ari took, Kevin could feel the jiggle off her cheeks from within the inside of her ass. As her ass jiggled and Kevin jiggled with it, he just couldn’t help but think about how incredible her butt was. He imagined what it must have looked like from behind with her tight shorts on. He was beginning to regret that he’d never taken a look at it around the house before.

 

Her cheeks were also moving up and down and as she walked. This made both cheeks grind up against Kevin from either side, of course brushing his cock as they moved.

 

Ari smiled as she thought about what she had in store for Kevin. He was going to have the time of his life. She felt the little man down in her butt as her ass cheeks moved. If you’d told her a-few days ago that Kevin would be a helpless little bug being engulfed between her ass cheeks, there was no way she would have believed you. Nonetheless, she was enjoying the whole experience incredibly.

 

“Hmmm… I think I’ll start on the treadmill…” Ari said. She knew Kevin would be able to hear her booming voice from down below, so she wanted to tease him.

 

Ari got on one of the treadmills and switched it on. She slowly began to jog, shaking Kevin’s whole world as she did so. Being a soccer player, Ari was very fit and in shape, so she would be able to run for as long as she wanted.

 

Ari continued with her light jog for 10 or so minutes, her ass cheeks still rubbing Kevin and his cock as she moved. She started to increase the pace over time. As she increased the pace and began to go faster, this upped the intensity for Kevin as well.

 

Ari’s cheeks jiggled and rapidly rubbed up and down the little man. Still brushing against his cock, Kevin was helpless to resist as he felt that all familiar rock-hard boner form. Her cheeks felt amazing against his member as they continued to grind against him.

 

As Ari ran faster and for a longer amount of time, she began to build up a sweat. She mischievously giggled and smiled to herself as she felt a drop of sweat forming on her forehead and rolling down her face. She knew what this would mean for her little man down below.

 

Things were certainly getting pretty sweaty down in her ass cheeks. Kevin was getting drenched in her ass sweat as she continued to run. He was beginning to get soaked from head to toe, some of her sweat entering his mouth as she ran. Kevin decided he was just going to drink in this sweat. If it came from Ari’s ass, he definitely wanted it.

 

Kevin breathed in and took a sniff. He smelled a pleasant smell. Ari’s ass was sweaty, but somehow that didn’t mean it smelled bad. Ari’s skin usually smelled like a bouquet of roses, so this mixed in with her ass sweat was a weirdly pleasant, and arousing smell.

 

Off the back of this, Kevin could barely take it anymore. At the start of the day, he really didn’t want to have more sexual experiences with his little sister, but in this situation right now he just didn’t care. His cock was literally throbbing. In between the jiggles of Ari’s ass, he managed to reach down and take off his shorts and underpants. His cock was now exposed in the cavern of Ari’s ass.

 

Ari’s ass sweat was acting as a sort of lubricant for Kevin’s cock. This only increased the pleasure as her ass continued to grind up against him, only pleasuring his cock more and more…

 

Ari continued to run faster and faster on the treadmill. She really wanted to put Kevin through his paces. She continued to up the pace, and up the pace, and up the pace until she was pretty much sprinting.

 

Down below, this was an almost surreal experience for Kevin. His whole world was being shaken between Ari’s ass cheeks as she continued to sprint. His cock was being rubbed insanely fast by the sweaty cheeks, and he felt himself edging closer and closer to climax. He was being thrown about inside her ass as it jiggled up and down with every single step.

 

Kevin felt it coming, oh that feeling. That perfect ass, the ass of his absolute goddess of a sister. That sweet smell, how powerful Ari was, she could do whatever the fuck she wanted with him. The way way she could just stuff him into her ass and there was absolutely nothing he could do or so about. These were all thoughts that raced through Kevin’s mind as he ascended to a whole new level of pleasure. “Oh, my fucking god!” Kevin screamed out as he reached climax. 

 

This climax was no regular climax. This climax was even better than when he’d previously been under her ass or between her breasts. Kevin lay there inside Ari’s ass shaking, completely in shock.

 

Ari continued to run on the treadmill. She was even slightly aroused at the thought of what Kevin would be experiencing right now. That’s when she stopped. She pressed stop on the treadmill as she could feel a tiny little squirt in between her ass cheeks. “Huh?” She thought to herself. Taking a moment to think what it could be. She smiled when she realised just what had happened.

 

Ari entered the bathroom, still a little sweaty from her run. She reached down into her ass and fished around her cheeks in search of her older brother. Finally finding him, she pulled him out and held him up to her face.

 

He was completely drenched in her sweat. It literally looked like he had taken a shower! Ari smirked at the sight of this, her tiny brother completely soaked in her ass sweat. 

 

She cackled with laughter as she saw that his bottom half was completely naked, and there was clearly a tiny (but huge to Kevin) load of cum that he had produced.

 

“You just couldn’t help yourself.” Ari chuckled. “I told you Kev, I don’t know why you ever thought to resist.”

 

Down on Ari’s hand Kevin was panting. It was almost as if he’d been the one running on the treadmill. Ari’s ass had given him a proper workout. He was in complete shock of the pleasure he had just received.

 

“Well, are you gonna say something?” Ari asked the man who was frozen in her hand.

 

“Tha- that was amazing…” Kevin managed to pant out. “You-your ass, it’s amazing.” He managed to say again.

 

Ari chuckled. “I told you Kev, I knew this was what you really wanted!” 

 

Kevin pondered for just a moment, trying to gather his thoughts. “What he really wanted.” Even a part of Kevin was beginning to agree with her… maybe it was all he’s ever wanted.

 

Before Kevin even had a chance to speak, Ari spoke.

 

“I need to get back to class, little guy. I hope you're ready, because you're going back in!” She said before stuffing Kevin back inside her ass for round 2.

 

That’s how Kevin spent the next half an hour or so: trapped between his sister's ass cheeks. He was being held completely still by the powerful cheeks as she ran some more, squatted, lunged and more. He wasn’t complaining one bit to be fair; he had thoroughly enjoyed himself. 

 

 

 

A-few hours later, school had ended. Kevin had been cleaned off by his little sister and was now back in her soft cleavage for the walk home.

 

As he lay there, completely trapped in her cleavage once again, he couldn’t help but think about the events of the day. He had enjoyed being in his sister's ass so much. Kevin was still feeling down about the fact he was being kept this size, and he was still pretty angry towards him mom and sister, but he had to admit that being this size came with some unbelievable perks.

 

He thought about Ari. What a goddess she had become to him in these last few days, how she was almost enjoying this as much as he was. 

 

Kevin began to worry that maybe he was enjoying some aspects of being tiny too much. Maybe this is what his mom and sister wanted, maybe they wanted to break him and make him submit to becoming their tiny little pet forever. 

 

The worst part about it was, if this was their plan, then Kevin knew it might be working.

 

He pondered as Ari walked along towards home, bouncing up and down in her cleavage.

 

 

Maybe… just maybe, this was his purpose…
