"Mmmmm~" The pair of mother & daughter hummed blissfully, enjoying the cool air of the fan wafting their faces from the merciless heatwave that had been wrecking evermore.

Nicole and Anais Watterson sat in the living room in their underwear, the former on a chair and the latter on the couch, sweating like pigs in a slaughterhouse. The television was playing some movie they couldn't pay attention to, as they were more focused on trying to cool off in the sweltering weather.

"Ugh... this heat is killing me!" The little pink bunny girl complained, wiping some of the dirty fluid off her forehead.

"Same here..." Her mom moaned. "We can't stay cooped up inside all day, we need to find a way to beat this."

Her matching pink bra & panties were soaked in the sweat, leaving Nicole's perky nipples and tight pussy showing through the dampened fabric.

Anais was just wearing a plain white pair of panties, but it was still just as wet as her mom's, and the fabric clung to her petite body, giving the older woman a good look at her daughter's developing form.

Unbeknownst to her, there was a guest residing in those panties, though she wasn't exactly enjoying her stay.

Penny, the angelic shape-shifter and girlfriend of Anais's own brother Gumball, somehow found herself shrunk down to the size of a walnut, and was unfortunate enough to find a vacancy in the bunny girl's underwear.

Despite her efforts to make her presence known, Penny couldn't make a sound that was loud enough for the Wattersons to hear, so all she could do was watch her boyfriend's sister try and endure the heat.

"No way I'm stepping back out there." The little rabbit announced, slumping in her seat. "I don't even wanna think about it..."

Nicole sighed. "Neither do I, but we're not gonna find relief in here either. Guess we better get the pool ready."

Anais frowned, slowly worming her arms to push herself up from the somewhat comfort of the couch.

"I guess you're right..." She groaned. "I'm gonna head upstairs and get changed."

Nicole nodded, standing up and scratching her butt, the sweat making an impression through the panties' material.

"Alright, I'll grab the pool and set it up."

With that, the two parted ways, with one of them heading for the backyard and the other heading upstairs.

Penny could feel the bunny girl moving about, the idea that she was heading upstairs coming to mind from the way her sweaty buttocks shifted.

'Wh- Where...?' She pondered, trying to collect her thoughts as she was shifted about with each movement.

With how Anais had been resting her huge butt on her for who-knows-how-long, her head was a little dizzy.

But if her unknowing captor was heading upstairs, then hopefully it meant she'd be getting changed into something else, or even get naked again.

"Oooh, I hope she takes a shower, I need to wash myself..." Penny thought to herself, feeling more than just a little gungy that her body was so stained from the bodily sweat.

As she neared the top, however, the sound kf the front door opening could be heard, prompting the bigger of the two to turn and see who had come back.

Unsurprising, it was none other than Gumball himself.

The blue cat wasn't sporting anything better than the girls of the household; a tank top and cargo shirts that revealed a generous amount of legs, and carrying a soda in his hand.

As soon as he got inside, it didn't take him long for his eyes to fall on, or rather, up to, his sister on the stairs, resulting in them widening before eventually hide them with his free hand.

"Ahhh!" He exclaimed quickly. "Jeez, Anais, put some clothes on! I don't wanna see that!"

"What, I'm wearing my underwear, it's not that big of a deal." Anais scoffed, placing her hands on her hips.

"Yeah, and it's not covering much, you know..." He muttered, trying not to look as he made his way up the stairs, too.

The girl rolled her eyes, before she got an idea. The memory of what she had done to him earlier that day crawled into her mind, and she was in an ideal position to do the same thing, up close and personal.

"Oh, so you don't want to see me wearing my underwear, huh?" She began with a sneaky tone, bending over as she slipped her thumbs into the waistband.

Gumball froze, his eyes peaking through the gaps between his fingers as his sister teasingly pulled the bottoms down.

"W- Wait, don't show me thaaaAAA-!" He screamed as Anais mooned him again, revealing her bare, sweaty, naked ass for the second time.

"You're welcome~" She grinned, turning her head back to him with a mischievous smile.

"Anais!" Gumball yelled, his face beet-red as he glared at her. "Come on, that's gross!"

"You asked for it!" The girl huffed, sticking her tongue out at him.

While the siblings bickered, Penny saw her chance to escape at last, merciful for the daylight and fresh air as she slid down her captor's panties.

She was close enough to the floor that she could safely make a landing on the soft, fluffy carpet, and she could start finding a way to get back to normal.

"Finally!" She sighed in relief, beginning to climb out of the dampened undies.

However, her luck was shot-lived, when the brother of the two made his retaliation move for the disgrace act he had been subjected to.

"Oh yeah?" He asked, quickly reaching down to where her panties now stood, apparently not noticing his girlfriend being present with them at the moment. "Well, YOU asked for THIS!"

Both the girls' eyes widened in horror, quickly realising what he was intent on doing at the same time.

Before either Anais or Penny could do anything, Gumball lifted her panties upwards, giving his sister an intense wedgie, re-sealing the angelic creature in place within the bunny's buttcrack.

"H- Hey!" The little girl squeaked, struggling against the tight, wet material riding in between her cheeks, kept in place via being lifted off the ground by her stretched undergarments, unable to do much else.

The other girl wasn't faring much better, now even closer in her unfortunate prison than she was before, the heat and sweat intensified by the newfound proximity.

"Oh no... this is even worse..." Penny groaned, grimacing as she was once again forced into the tight crack, feeling every inch of Anais's flesh rubbing against her, the stench of her sweaty body overwhelming her.

But this was a whole new level of torture, now that her face was being pressed against some kind of tight entrance. And it didn't take her long to figure out what it was.

'You've got to be kidding...' She thought with a shudder, not wanting to believe that she was now right in between Anais's buttcheeks, her nose touching the puckered hole.

The only thing Penny could do was keep her mouth shut and hope she wouldn't be smothered, which was harder than it sounds, especially considering her boyfriend was unknowingly pushing her even further towards her.

As for Anais, she had mixed feelings going through her mind from the wedgie.

The way her underwear was being riled into butt and her... Naughty bits. What were they called? She wasn't that far in Sex Ed class to learn all that stuff. But whatever it was called, it gave her a measure of pleasure and pain.

It was almost like a weird massage, and while it was kinda embarrassing for her brother to give her a wedgie, it felt pretty good.

"There, you look pretty well-dressed now!" Gumball teased, letting go and letting her fall to her feet on the carpet.

"You jerk." She muttered, crossing her arms and looking away, before proceeding to her room. "I'll get you back for this. Later."

The boy smirked to himself, watching his sister march away before she disappeared behind the bedroom door.

"That'll teach her not to flash her butt at me." He chuckled, taking a sip of his soda as he walked to his own room.

Once she was in her room, Anais hopped onto her bed, trying to process the feelings that were running through her mind.

Why did she let her brother do that? Was it some kind of weird enjoyment she had that she wasn't aware of, or was it just the way her brother teased her?

She was sure that this was a somewhat normal thing for sisters and brothers to do, but it wasn't supposed to feel good... Was it?

The fact she hadn't even fixed her wedgie yet probably spoke towards that, the girl still thinking about what had just happened.

And so did Penny.

Forced up against the bunny girl's anus, the poor angel was in a worse situation than ever, the smell of her ass invading her nostrils, the puckered entrance twitching slightly above her face.

'This is a nightmare...' She thought, wanting to cry as she was so close to what could've been a horrid demise.

She wanted to squirm, she wanted to scream, she wanted to break free from the prison of panties, but it was useless, nothing she did seemed to even loosen them a little bit.

Meanwhile, Anais remembered that she had come up for a reason, and that it would involve having to remove her underwear entirely.

"Okay, time to get this off..." The girl said to herself, grabbing ahold of her panties and pulling them away from her crack, feeling them slip further into her snatch in thr process, bringing back the strange sensation she was experiencing earlier.

'Ngh!' She squeaked in her mind, a shudder coursing through her body. 'This feels... different...!'

Curiosity got the better of her, so she pulled again, and the same thing happened.

She repeated the action a few times,  back and forth, experimenting with her underwear, and soon a sense of pleasure washed over her, a feeling like nothing she had ever experienced before.

"W- Wow... What's this...?" She asked, looking down at her crotch and the panties she was playing with.

As her wedgie pulled her panties tighter and tighter, her nether regions reacted with a pleasurable sensation, the girl finding a new form of entertainment for herself.

She didn't notice, but she had unwittingly pulled Penny further inside her butt, the angel finding her face now firmly pressed against her anus, the warm, wet walls of the bunny girl's rectum.

Penny didn't realise, until her vision was taken by a black void, her world shrinking even more.

"W- Waaahhh!" She cried out in surprise, though the sound was muffled by the panties, and Anais's butt, rendering her voice silent.

Speaking of, the young bunny couldn't resist wanting to know more about this amazing feeling, and now that there was nothing but air in the way of her hand and those wet folds between her legs, the girl reached inside, curious to feel what made the latter feel so special.

"Mmm...!" She moaned as her fingers met her pussy, and her eyes widened as they sunk into the folds. "Wow..."

It felt too good to stop, and with her panties already pulled in, the girl started masturbating, rubbing her clitoris with her fingers, slowly but surely building herself up towards the first orgasm of her life.

'Ohhhh, no, no, no, no, no, no, NO!' Was all Penny could think to herself as she could feel Anais sliding down to get in more comfort position, further crushing her underneath her weight.

'Not this again... Please, not this again...!' The angel thought desperately, trying to break free.

She could only imagine what was coming next, and if she couldn't stop it, she was in for a very unpleasant experience.

Which was more than could be said for Anais, who had started fingering herself.

With her panties stuffed down her crack and her fingers deep in her pussy, the girl was lost in the ecstasy, the pleasure of her wedgie and masturbation sending her mind into a haze.

"A- Ahhh, wow~ This feels... so... good...!" She cooed, her eyes rolling back in her skull, her tongue hanging out in bliss.

Meanwhile, Penny was starting to suffocate, Anais's ass completely crushing her.

She never, even in the wold and unpredictable city of Elmore, expected rhat her end would come in the form of her boyfriend's little sister's butt.

"A- Anais..." She wheezed, trying to plead for her life. "Please... Let me out...! You're... You're gonna..."

But she didn't hear her. She couldn't hear her. Even if she was normal sized, the little pink one was too immersed in her pleasure to notice, the world around her a blur as she was brought in her own little world of bliss.

Suddenly, she flipped her body frontwards, getting on her stomach with her hand reaching underneath her, the sudden movement sending her captive flying upwards in the air.

"Whoa!" The yellow creature exclaimed, flailing her arms and legs instinctively, trying to catch herself.

Of course, it didn't work, and she just ended up landing in the arms of something else. Something soft, plushy and pink.

"I love you~" The toy announced, having activated upon landing.

This seemed to get the bunny's attention,  swiftly looking back to her favorite plushy with affectionate intentions.

"Ohhh, Daisy~!" Anais exclaimed gleefully, crawling over to the donkey. "I love you, too!"

In her lustful state, she still didn't notice her little guest when she turned the toy over to be lying on its back, or even when she held her firmly in place with her hands.

This was bad news for Penny, leaving her pinned down once again. Not by her butt this time, thankfully, but she was still trapped.

"Ughh..." She moaned softly, shaking her head to regain her vision and take in her new surroundings.

However, the first sight she saw didn't seem like too much of an upgrade.

Rather than her colossal posterior about to pin her down again, she was met with the same bunny leaning down with her eyes closed and her lips pursed, heading straight towards the yellow shape-shifter.

"N- No...!" The angel exclaimed, trying to push away from the toy, but with how firmly the pink bunny had her gripped, there was no escape.

With her eyes closed, Anais didn't even know where she was placing her lips, or what was beneath her, but that didn't matter, and she planted a wet, sloppy kiss on her toy(s)

Penny had to resist the urge to gag as her body was kissed by her boyfriend's sister, feeling her lips against her whole body.

Her mind was racing a million miles an hour, trying to make sense of everything. Though the feeling of her wild saliva coating her made thinking about anything a little tricky.

'Oh, this is so gross...!' She shuddered, feeling the drool dripping down her.

She couldn't take this anymore, she had to do something, ANYTHING, to break free.

All the while, Anais was in paradise, imaging her best friend returning the affection and kissing her back.

Not a moment too soon, the little rabbit broke the kiss, but Penny didn't get much time for respite, before she found herself sandwiched again.

This time, between the plush toy and her captors bare, sweaty chest, in a tight, overly loving hug.

"Oh, Daisy..." She cooed, holding her toy firmly. "I've wanted to kiss you for so long... I've loved you since the day we met! You're so beautiful and cuddly, and I know you love me too!"

"Ughh...!" Penny groaned, feeling her lungs being squeezed between the two obstacles, one of sweat and flesh and the other of stuffing and fabric.

'Gotta... Get out...' She thought to herself, struggling to keep a hold of her consciousness. 'Need... To...'

Anais didn't even realise the amount of pain she was putting her toy in, nor did she have any intention to. All that mattered to her was getting pleasure, whatever that took from her.

That's when she got another idea.

Letting go of her precious doll, the little bunny placed her very favorite friend, and the little angel creature that it had now been accessorized with, flat on the bed in front of her, before she plopped back on the bed with her legs spread in the air.

"Hmmm, what's the best way to do this...?" The pink rabbit pondered aloud, tilting her head.

'Do what...?' Penny thought, hoping to goodness that she wasn't about to be crushed or suffocated again.

"Ahh, what the heck. Let's play footsies~!" She giggled, moving her feet towards the toy at either end.

The little angel's eyes widened, as did her mouth, the sight of those giant sweaty feet making her fear for her life.

'No no no no no!' She thought, the panic rising in her voice, her mind racing. 'Don't squish me! Don't-! AHHHHH!'

Her plea was cut off by her own scream, the rabbit girl's sole pressing into her body, trapping her once more with her sweaty body.

But this one was probably the worst of the torture so far. Easily worse than her butt.

The smell, the heat, the pressure, all of it was just too much for the little shape-shifter.

Anais didn't seem to notice, or even care, as she proceeded with her footsie game, pressing her toy with her feet and massaging them up and down, as if to be giving it a pleasurable action.

"I've always wanted to do this~" She said in a singsong voice. "You're soooo cute and fuzzy~"

"A- Ahh, ughhh..." Penny groaned, struggling to endure the vile sensations. "H- Help..."

She could feel every single inch of the girl's sole on her, rubbing her fur, skin and sweat into her, the wretched stentch invading her nostrils while her toes gripped her tightly.

"Mmmmm~ This is so fun~" The little girl sighed, rubbing her feet together and trapping her tiny guest within the soles as she gave the toy's snout a foot job.  "I wanna play with you forever, Daisy~"

'No, please, no...!' Penny begged, the feeling of the giantess's feet being rubbed against her taking its toll. 'Just let me out, please...!'

Of course, Anais wasn't going to hear, as her mind was now set on her new form of entertainment, the bunny girl getting a new kick from the footplay.

The feeling of control she had over the doll, as well ad the tingly feeling in her little vagina, was getting her all hot and bothered.

It wasn't long before she wanted to take things further, getting the best of both worlds.

"Ohhhh, Daisy!" She exclaimed, moving from sitting on her bum to her knees, getting above her precious toy. "Great idea!"

Penny, despite being free from the feet, didn't get to enjoy the feeling of sweet freedom for long, before a shadow loomed above her, the angel turning her gaze to the giant creature towering above her, her eyes meeting the bare, sweaty pussy of the bunny girl.

"Have mercy..." She said, her voice shaking as the sight of impending doom took the form of a four-year-old anthropomorphic bunny girl's vagina.

Anais didn't waste any time, and lowered her hips until her snatch was directly on top of her toy, and she proceeded to give it a hug with the wet folds, using the toy as a plushy dildo.

"Ahh, this feels so good~!" The girl cooed, grinding her hips against the toy, trying to worm it in even deeper into her snatch.

The poor little angel was now trapped yet again, her body pressed between the plushy and the girl's crotch, getting buried in the moist folds.

'No, no, no, no, no, no, no, no, no, no, no, no, NO!' She cried out internally, trying desperately to escape.

Her body was pressed against the toy, and now was being forced into her hot, sweaty little cunt, the juices leaking down her face, her eyes, her wings and her body.

The only upside was that she was too small for her to actually be swallowed up or get stuck, though the heat, smell and fluids were still very much there, and were overwhelming her senses.

"Ahhh, mmmm, yes~!" The rabbit girl moaned, rocking her hips back and forth, grinding her clit with her toy. "So... Hot... So... Wet...! Mmmmm~"

Penny had to close her eyes to prevent the stench and fluids from getting in, but it did nothing to stop the horrid sensations.

Her ears were full of the gross squelching sounds, as well as the muffled moaning and groaning, and her nose was full of the musky odour of her prepubescent pussy, the taste of the bodily fluids making her want to throw up.

'Please, somebody... Anybody...' She begged internally, hoping that somehow, by some miracle, she could escape.

But she had no such luck, as she was now trapped inside the girl's snatch, as she pleasured herself with her stuffed donkey like all was well in the world.

"Mmmmm, yeeeessss~" The pink bunny moaned, grinding her hips and her pussy with the toy.

Penny didn't even try to move anymore, knowing full well that nothing would get her out of this mess until she was finished with her special little playtime with the toy.

She just kept her eyes closed, and let the bunny ride her, waiting for the climax to arrive.

As for the pink rabbit, her body was in heaven, her pussy throbbing in pleasure as she enjoyed a time with her beloved Daisy like she had never had before.

The little plush donkey was pressed into her vagina, her legs kicking and her tail twitching as she humped her little butt and rubbed her nose against her clitoris, stimulating it and her entire crotch.

"A- Aaahhhh~" She moaned, her hips trembling as her vagina walls spasmed. "D- Daisy, wh - what are y- you...!"

She didn't get to finish the question of what was happening to her body, before she came for the very first time, her snatch squirting as she orgasmed, squealing in pleasure as her juices gushed out of her little body.

"AAAAHHHHHH!" Anais screamed as quietly as she could, waves of pleasure exploding out of her and staining her toy.

Penny didn't stand a chance as she was drenched in the cum, the fluid filling her mouth and eyes, and the girl's snatch squeezing her, the girl's inner walls trying to milk her of everything.

"Arrggghh!" She grunted, feeling her entire being getting compressed and drenched at the same time, like standing beneath a gooey, sticky waterfall, the pressure threatening to pop her.

However, the little rabbit finally stopped her climax, her vagina walls relaxing and the flow stopping, allowing her prisoner to finally escape the horrific confines.

Slowly but sure enough, Penny was able to slip downwards and finally make her way out of the vagina, returning to the world with fresh air.

"H- Haahhh..." Anais panted above her, catching her breath while her vision coming back into focus and her body going limp, the euphoric feelings clouding her mind as she struggled to stay up on her knees.

Which was bad news for her former captive, who had chosen exactly the wrong moment and direction to try making a getaway from the oblivious, torturous bunny.

She was still blinded by the gross fluids in her eyes and partially deafened by the cum in her eyes and ears, so she likely didn't notice where she was heading to; underneath the bunny girl's arse.

Not until it was too late to do anything about it, that was.

With her shaking legs and her body exhausted, the youngest Watterson let herself plop down, once again trapping the yellow creature underneath her butt, her underdeveloped cheeks crushing the angel, as her head fell into the bed, her vision going black as her eyelids drooped, and the bunny felt herself drifting away, her snatch leaking.

"Mmmm~" She cooed, panting heavily after such an amazing activity.

"Mmmmph!" Penny cried out, unsure if she could even keep her sanity from being crushed beneath her buttocks yet again.

She was starting to lose count of how many times this had happened today.

"Anais!?" The cat mother called out from the outside, prompting her daughter to lazily open an eye as her name was called. "The pool's ready! Are you coming?"

The little bunny had forgotten about what she had originally come in her room for, but she suddenly didn't feel like joining her mother right now.

"G... Give me a minute, mom..." She called back, closing her eye and wiggling herself to get more comfortable. "... Or 100..."
