She's A Cheeky One!

"I'm homeeeee!" a voice cooed from the front door. 

Sam turned from the couch to greet his roommate as she walked through the door. Olivia was just a bit taller than average with short, curly orange hair. Her volleyball jersey fit perfectly over her pale, thin frame as it hugged her small, yet perky b-cup boobs. The fabric curved inward against her thin waist and naval, eventually flowing outward as it reached the curves of wide hips and toned butt. 

Her runner's shorts left little to the imagination as they so snuggly wrapped themselves around every curve of her thick lower body and sank into every nook and cranny they could find. Even though Sam had been roommates with her for nearly a year now, he was still shocked by her beauty and constantly had to fight the urge not to stare at her.

"Hey, Liv!" he casually said a smile and started waving, still lost in his thoughts about how great she looked.

Liv walked inside and turned around to shut the door. Sam's eyes quickly darted to her ass, her buttcrack clearly distinguishable against the tight fabric. As Liv started to turn around, his eyes quickly shot back up to hers, too distracted by her body to realize that he was still waving at her.

Liv raised an eyebrow and looked concerned.

"Umm, you can stop waving now, you weirdo," she said, starting to smile. She laughed to herself and gave a quick wave back as she disappeared down the hallway and into her room.

Sam looked at his still-waving arm and immediately stopped. He could feel the color rushing to his cheeks. Why was he like this? He was just so awkward sometimes, especially around Liv. They had only started dating a few weeks ago, but he wondered how much of his dorkiness she could deal with before going back to being just roomates. He took in a deep breath, sighed, and headed to the bathroom.

After finishing his business and washing his hands, Sam looked up from the sink and took a look at himself in the mirror. He honestly thought he was a pretty good looking guy. He was tall, slim, and had a nice tan going on. He had been told by many women that he his blue eyes were fantastic and that he had a great smile. He ran a hand through his dark black hair and tried to tell himself everything would be fine.

Sam spent the next few hours at his computer with his head resting on his fist trying to take his mind off things. His other hand mindlessly scrolled on his mouse through his feed, occasionally smiling or exhaling slightly louder than normal when he came across a funny meme.

Suddenly, his eyes came across a rather interesting ad. They were lured in by the extremely curvy ass in a tight bikini bottom that filled up 1/3 of the ad banner. 

"Cheeky!™ - an experimental butt cheek enlargement pill. Don't settle for other half-ASSED supplements, try Cheeky for FREE!" the ad read. 

Sam sat up with interest, raised his head off of his hand and clicked on the ad. He spent the next few minutes reading about the pills. They did indeed offer an entire box-load of pills for free. Heck, he didn't even have to supply them with a credit card. He had his doubts about their effectiveness, but it wasn't like he had anything to lose. He typed away at his keyboard, punching in his address and then submitted his order.

Deciding that it was getting late, he turned off his computer and got into bed. 

The next morning, Sam got out of bed and slowly made his way into the kitchen to make himself a quick breakfast. After a few spoonfuls of cereal, Liv came in through the front door with a package in her arms. She was wearing a tight, spandex unitard which was her usual attire for her morning jogs. 

"Good morning sleepy-head!" Sam teased. "I've got a package for you!"

She placed a cardboard box on the table and then walked over to the living room to do her post-workout stretches. She bent over with her back facing Sam. Her wide hips and prominent butt on full display as she did so

"She HAS to be doing this on purpose to torture me," Sam thought to himself.

He glanced over to the box on the table and was shocked as he read "Cheeky™" on the side of it.

"That was fast," Sam said to himself.

"Hmm? Liv asked, as she looked back at Sam upside-down from between her legs . "What's in the box? What didya get?"

Sam panicked. "Oh," he stammered. "Umm, I didn't get anything...for ME. Uhh...these are for you!" he said with a smile he hoped didn't look as fake as it felt.

"Really?" Liv asked as she made her way towards the table. "Why's that?"

"Uhh, it's...for... your birthday!" Sam explained.

"Aww," Liv said. "That's so sweet of you."

Suddenly, she frowned and looked down.

"But wait a minute," she said looking up. "My birthday isn't until next month."

"Uhhh, well.. the shipping was a lot faster than I expected," Sam said, relieved that this one statement was technically true. 

"AWW!" she exclaimed. "Well that's so nice of you to think ahead so far like that."

Liv had always been a bit of a ditz. Sam didn't think it was really a bad thing, it was more cute than anything.

Liv walked up to the box and opened it up. She pulled out several cellphone-sized plastic containers that rattled with pills as she placed them on the table.

"What are these?" she asked curiously.

Sam's eyes widened. He couldn't just tell her that he had bought her booty-growth pills. He nervously looked around. To no one's surprise, his eyes landed on her unitard.

"They're uh....workout supplements!" he explained. "I figured you'd want to get the most out of your exercise sessions and volleyball practices and what-not."

"You are just the sweetest!" she said as she started to open up one of the plastic containers. 

"Thank you so much!" she said, giving him a quick peck on the cheek.

"You're welcome" Sam said hesitantly as she dumped the entire packet's contents into her hand and put them into her mouth.

"Woah, woah," Sam said with a worried look. "Shouldn't you read the directions and see how many of those you should take at once or something?"

"Oh it's fine!" Liv retorted. "They're workout supplements. That means they're good for you! You can't have too much of something good for you, Sam."

Sam could think of quite a few exceptions to that statement, but decided it was probably fine. After all, they were free. It was probably just a marketing ploy to get his address on a spam letter list or something. They probably didn't even do anything.

"Well, ok. Just stop taking them if you feel weird or something," Sam said.

"Sure thing!" Liv said after chewing and swallowing 3 or 4 pills.

"Mmm," she exclaimed, her eyes widening. "There's a really nice sweetness to these!"

She savored the flavor for a little longer and then walked back to the corner to resume her stretches.

Sam looked back down at his cereal and continued his breakfast. He grabbed one of the boxes and read the directions on the side. 

"For safest results, take 1 - 2 pills per 24 hours. Do not take more than 8 pills in a single week, otherwise unpredictable side effects may occur."

After he finished reading the rest of the warnings and ingredients, he looked back up to catch another glance at Liv. His eyes widened.

She was lying down on her yoga mat in a upward-facing dog pose. Her ass was noticeably bigger than it had been just moments ago. It bulged heavily against the tight unitard that fit the rest of her body so comfortably.

"Is everything ok?" she asked.

"Oh, yeah...everything's fine. I'm sorry," he stammered.

Liv got to her feet and started walking to the hallway. "Are we still on for our date to the mall later?" she asked.

"Oh!" Sam said. He had nearly forgotten. "Yeah, of course!".

"Great," she said, "I'm going to take a quick shower and get dressed, then we can go."

"Sounds... good!" Sam said nervously.

He watched as she turned the corner and walked down the hallway. Her ass cheeks jiggled and wobbled back and forth like 2 plates of Jello as she strutted into the bathroom.

Sam buried his face in his hands in disbelief. They actually worked! The pills worked! He was feeling an entire spectrum of emotions, from worry and shock, to excitement and lust.

Later, Liv returned to the kitchen in an athletic tank top and runners shorts. She scooped up all the boxes of pills into her purse and headed towards the door, the fabric of her shorts stretched to their limit to fit her expanding butt cheeks. The tops of them poking out from her struggling waistband.

The pair made their way to Sam's car. Liv sat down in the shotgun seat, her ass cheeks spreading out twice as wide as they did just a few hours ago. Their size caused her upper-body to be a few inches  higher than what she was used to.

"Did I, get... taller?" Liv asked, confused. 

"Oh, have you?" Sam said with a gulp. "I haven't noticed".

Liv bit her lip in thought. "Oh, I bet I know what it is...It's all the stretching I did this morning!"

Sam chuckled nervously. "Um, hehe, yeah, must have been that."

As Sam put the car in reverse, he noticed Liv pulling another box of pills out of her purse.

"I reallllly think you should take it easy on those," he said, no longer attempting to hide his worry.

"Hey! Who's the fitness expert here, mister?" Liv retorted as she put another handful of pills into her mouth.

Sam decided there wasn't anything he could do to convince her to stop. As they made their way down the road, he noticed Liv moving out of the corner of his eye. Her ass cheeks continued to grow, lifting her higher into the air. Her seat belt was slowly extending to account for her growing body. 

When they finally reached the mall, Sam put the car in park in glanced over at Liv getting out of the car. She had to lift a handful of booty cheek out of her way to reach the buckle. It snapped back with relief as it retracted. 

Her head was now almost brushing against the roof of the car. As she turned to exit the vehicle, she bumped her head on the door frame.

"Ouch!" she whispered to herself, then muttered something about how tall she was getting.

Sam got out of the car and met her on the other side. Her ass was GIGANTIC. Her cheeks were sagging heavily against her straining running shorts. Big handfuls of booty flesh overflowed out of the top of them. Several inches of her butt crack was now on display. Liv found herself absentmindedly tugging them up, only for her enormous jiggly ass to push them back down.

Once Sam walked up to her, he noticed she HAD been getting taller. She was at least an inch taller than she had been this morning.

As they made their way across the parking lot, her ass cheeks violently sloshed and jiggled with each step she took. Sam could see they were still growing as she walked! He was impressed with how well the pills targeted only her butt cheeks. Her hips and thighs remained exactly the same except for the height! He supposed they didn't call it "Cheeky" for nothing.

As they entered the mall food court, Liv turned several heads as her massive backside jiggled and wobbled behind her. She didn't seem to notice, or at least didn't seem to mind the extra attention. She had always been an attractive girl, but Sam had doubts she got THIS many stares.

They made their way to one of the restaurants and ordered few burgers with fries to bring back to one of the mall tables. After picking up the tray of food and turning towards Liv, he noticed she was still getting taller. She had grown at least another inch or two since they had walked in.

Liv turned around to go find a table. Her ass cheeks had grown to size of beachballs at this point. Hardly any of their mass remained in her struggling running shorts. The other 95% of her ass was out and jiggling for all to see as she walked. Sam's worry started to be replaced with desire. He started to wonder just how BIG they would get. 

Once they finally found a table, Sam eagerly grabbed on of the chairs and pulled it out for her. 

"Allow me!" he said with a smirk.

"Wow, what a gentleman!" Liv cooed. "Thank you."

As Liv set her gigantic ass down on the chair, it overflowed the seat in every direction and oozed out heavily in between the bars that made up the back. Luckily there were no arm rests, otherwise there was no way she would have fit. Instead, huge globs of ass fat simply hung over the sides of the chair. 

Sitting down, Liv now several inches taller than Sam. But this didn't seem to bother her as she absent-mindedly took a bite out of her burger. 

"Hey Sam," she said. "Is it ok if we go clothes shopping after we eat? My shorts have been feeling a bit snug recently. I need to find something better suited for my new height!

Sam smiled as he tried to imagine how on earth being taller would equate to needing wider shorts, but opted to just smile and agree instead.

"Oh! I almost forgot to take my supplements!" Liv exclaimed. "The walk from the parking lot was pretty long, plus it's always good to take some before you eat. I think I should have a few more than usual!" 

Liv reached into her purse and pulled out box after box while she ate. Popping them into her mouth like candy while she had her meal. By the time she finished eating, she almost couldn't reach the table her ass was lifting her so high up into the air. Huge jiggly handfuls of ass fat nearly reached the floor from her seat. 

After their meal, Liv got to her feet. She had to be at least half a foot taller now. She stumbled back, not yet adjusted to the massive weight she carried behind her. 

"Shall we?" she asked Sam, not noticing that the entire food court was gawking at her. 

"S-sure!" Sam replied.

Liv turned to walk towards one of the clothing stores. As she did so, her gigantic ass cheeks slammed into her chair and sent it several feet across the floor.

"Oops!" she teased. "This booty is a lot stronger than I remember. Those squats must be paying off!"

"Must be!" Sam said, trying not to laugh.

Her humongous ass cheeks nearly reached the floor as she walked now, the back or her heels bumped against them as she walked, but none of this seemed to phase her in the slightest.

The couple made their across the main floor of the mall towards the stores. Liv's ass continued to grow with every step she took. But not only that, her growth seemed to be accelerating. Her ass was now on full display, too big to even be partly contained by her impossibly small shorts.

"Oh, I should probably take my post-meal supplements!" Liv said, taking a few more boxes out of her purse and popping them into her mouth as she walked. 

At this point, her booty cheeks grew so large and heavy that they started to drag on the ground behind her. While her height was steadily growing, it was just nowhere near the pace of her butt cheeks.

 Everyone within 50 yards of her was staring with their mouths agape. People walking past her gave her a wide berth as they watched the 2 mountains of ass flesh wobble past them.

Once they reached the clothing store, Liv walked around a few aisles, only managing to knock over 3 displays with her giant caboose as she traversed the store. 

After some digging, Liv found a pair of shorts only 1 size larger than the ones she had rendered useless and held them up.

"Hey Sam, what do you think of these? Super cuteeeee right?", she teased.

"Haha, they do look cute. You might want to make sure they fit before you buy them though," Sam suggested.

"Duh!" Sam replied. 

She started to make her way towards the store's fitting room. Her butt cheeks dragged several feet behind her as she walked. She was visibly struggling to pull them along with her. Sam walked along with her as she huffed and puffed her way across the store.

"Man, I'm pooped!" she said, catching her breath. "That run this morning really must have tired me out. I bet it's nothing a few more supplements can't fix though!"

Greedily, she swallowed another handful of pills. Easily passing the 6-foot tall mark, she made her way into one of the stalls, but suddenly stopped as the two planets of flesh she was pulling behind her bulged into the doorway.

"Wow, this changing room is so tiny! Sam, can you give me a quick push?"

"Um...sure!" Sam said with excitement and reached out his hands towards her gigantic ass. 

As he shoved, he felt his hands and upper arms sink deeply into her soft squishy butt meat. He could feel her flesh tingling and growing in his hands as he pushed harder and harder. Handfuls of pure softness grew between his fingers.

Liv unexpectedly started to moan as she felt her bare ass being groped and pushed. She bit her lip as her nipples began to harden and swell.

With a few more grunts and shoves, Sam finally managed to to shove her ass past the threshold of the changing room. Liv barely had enough room to turn around and close the door. As she did, Sam's eyes widened as she noticed her nipples were visibly growing too now. Erect and enlarged, they bulged obviously against the fabric of her form-fitting tank top. 

"Thank you!" Liv said between breaths. She waved her hands near her face trying not to get too hot and bothered from the unexpected amount of pleasure she had just experienced. Thinking that maybe a few more supplements would calm her down, she emptied the last box into her hand and took them.

After just a few seconds, Liv's ass made contact with the back of the room, slowing pressing into the bench and mirror. It started to force her forward until she was pressed against the door. Her ass cheeks continued to grow at an alarming rate. She felt herself getting pushed harder and harder into the door.

"This room is so tiny!" she said to herself. 

Suddenly the mirror cracked behind her as the pressure from her growing butt became too much for it to handle. It fully engulfed the small bench mounted on the way until breaking it off completely. The sides of her ass pressed against the sides of the room now, the wooden walls beginning to groan and strain against the immense pressure.

"Is everything ok in there?" Sam asked with a hint of worry.

"Oh yeah, everything's fine. This changing room is just a little... cramped...is all." she answered.

Sam noticed he could now see the top of her head starting to peak out from above the door, and behind it was an ever growing pile of booty cheek. The wooden walls of the room started to splinter and crack as her expanding ass started to fill every square inch of space inside of it. Finally it was just too much for the door's lock to handle. The door burst open, sending most of Liv's body out with it. Her butt cheeks, however, were still stuck in the weakening changing room.

"Oh that's much better, but Sam, I think I'm stuck!" Liv said, looking behind her at her megaton ass.

Suddenly there was a loud series of cracking noises as her butt cheeks exploded out of the changing room, sending chunks of wood and drywall in every direction. 

"Ahh, nevermind!" Liv said happily among the piles of splinters and dust she had just created. 

After the initial shock of the explosion was over, Sam got a good look at the new Liv. She must have been at least 7 feet tall now. As her butt cheeks continued to expand, she found herself sitting on them instead of standing though. They slowing continued to grow and raise her legs off the ground. Looking down, her nipples were gigantic now. They looked like stuffed sausages poking into her tank top.

Meanwhile, everyone else in the store had turned to see what had made all the noise. Luckily no one had gotten hurt, but a few started to head towards the exit, not wanting to take any chances.

Liv tried to stretch her toes to the ground, but couldn't reach. Her ass had gotten too huge. It continued to expand, engulfing every changing stall, clothing rack, and shopping cart it bulged over.

"Hey Sam, I'm stuck again!" she said, wiggling her legs back and forth. 

With the changing rooms so close to the exit, the other patrons started to realize that they might not be able to get out of this building if her growth continued to accelerate like it had been. Mobs of people began running for the exit trying to beat Liv's growing mounds of ass flesh to it.

Sam was feeling a mixture of fear and excitement as he watched his date's ass continue to grow in every dimension. 

"Sam, I'm scared! What's happening? Everything is breaking and falling apart!" she cried as her ass knocked over an entire shelving unit.

Sam did his best to reach up and give her the most comforting hug he could. Her ass was now pressing against the ceiling above them. It expanded sideways until it bulged against the corner wall near the exit. Suddenly they both felt themselves start to move as the pressure slowly moved them across the ground to make adequate space for her store-filling butt cheeks. As they continued to move across the floor, her ass started to burst into the ceiling above them. Luckily this was a somewhat small store and only had one floor. Floor panels, metal struts, and other roofing pieces began crashing down behind them as her booty tore apart the building from the inside. Loud crashes from shattering glass echoed around them.

Sam suddenly realized that the other wall was only a few feet in front of them now. It was only a matter of time before they were crushed between the concrete structure and her building-wrecking booty. He held onto her as tightly as he could as he took in a deep breath. He closed his eyes and waited for his doom. 

After a few seconds of not dying. He opened one eye and looked around. They were still moving, but their speed was slowing down. They were barely moving now. After a few more seconds, they stopped completely. 

He looked around the store but could only see ass in every direction. He could still hear pieces of ceiling falling from somewhere outside. Her obese booty cheeks pressed heavily into the floor creating a creator about 2 feet deep. Cracks in the tile expanded outward in every direction her gigantic cheeks hadn't yet devoured. 

"Hey Sam?" Liv asked.

Sam looked up at his larger-than-life date.

"Do you think I can get some more of those supplements while we wait to  get unstuck?"
