Just when you were trying to tune out your mom's peculiar way of cuddling, you were hit by a gigantic blast that put her previous massive farts to shame, a rumbling thunderclap that hit you with a much larger and more powerful hurricane-sized torrent of hot, swirling winds that made her gargantuan, jiggly cheeks rumble and clap to the beat of its tremendous roar.

"Thank god he was up for it. I swear I can't hold them in when they start getting this big" You heard her giggling, and you probably would've gotten way angrier if you didn't just feel like you got nuked in the face at near point blank. You somehow still felt your bones rattling, your skull in particular.

You wondered for a moment why this felt so much stronger but then quickly remembered that Caren shrank you to half your previous size, which was already pitifully small. You were now as small as some of the smallest ants you'd ever seen, trapped in a place such a tiny creature would've been easily annihilated. Weirdly enough, that brought your mind back to a memory...

It was just one random day when you were about 5 years old, playing with Lillian in the park. The two of you began to feel hungry, with her round stomach making some loud and almost angry sounding gurgles that you both found hilarious. As you walked back to where your mom was, who had been sitting on a nearby bench and watching you, you saw that she had gone for a bite herself, she was coming back just as the two of you arrived, with a large, greasy burrito already bit in half in hand. You two giggled, knowing that she simply just couldn't resist seeing a stand or cart selling the stuff, and then wondering if her figure was getting too big.

For some reason, you took a glance at the spot on the bench where she was going to sit and there you saw it, a tiny, black ant that couldn't have been larger than a single millimeter. You remembered that your mom called them "hormigas locas" [Spanish for "crazy ants"] and she had taught you that they were harmless, as she never knew them to bite. And she tended to be unlucky with bugs in general, so it was like an amusing rarity.

That ant found itself instantly covered by a massive shadow as your mom turned around and sat down, plopping down her huge butt, clad in some tight booty shorts that barely covered her huge, round meaty globes. The unfortunate insect was apparently instantly consumed under all those pounds upon pounds of fatty flesh wrapped in a thin layer of almost skintight fabric.

Miriam noticed that you and Lillian were giggling while looking at her and after taking another big bite of her burrito, speaking after she swallowed.
"What's so funny this time?" She asked with a curious smile.

"Auntie Miriam sat on a bug" Lillian replied, revealing that you hadn't been the only one to witness.

"Huh?! I did?" Your mom quickly got up, panicking since she thought it'd be something that'd bite her, and she definitely didn't want bug bites on her body's most prized asset. When she stood up, all 3 of you looked at the seat and found no signs of that little ant. Miriam herself scratched herself in confusion while you two got a more baffled look. Thinking that it was some kind of joke on your part, she sat back down. You even felt the bench shake slightly from her weight as she did so.

"I think that bug got lucky and it got away before getting squished" Miriam giggled, but then she saw that you two were quiet and were still looking at her butt.

"Wow, she ate that ant" Lillian said in obvious amazement. Your own eyes widened in surprise, yep, that ant was gone from the bench, and there was only one place where it could have gone...

"Oh, it was just an ant" Miriam sighed in relief but then raised an eyebrow "Wait, what do you mean I 'ate' it?"

"Your butt ate that ant, Auntie" Lillian giggled, pointing at Miriam's hips.

"What?!" She finished the rest of her burrito in a single bite and dusted off her hands before quickly getting up. Even though she despised the bugs that stung her, such as scorpions and some kinds of ants, and most amazingly, even cockroaches according to your dad and Sheila, she didn't hate all bugs and was content to spare any innocent one she found, although her huge butt didn't appear to have gotten the memo as it had squashed many of them flat under its tremendous weight.

Miriam then saw that her shorts were bunching up quite a bit into her crack, giving her an unintentional wedgie that she hadn't even felt, most likely because she was so used to wearing thongs. She turned her plus-sized behind towards you and Lillian and asked if you could find the ant, and much to her own chagrin the answer was 'No'.

"Then, I guess I know where it is" She said and reached towards the back of her shorts to pick out the wedgie when a surprisingly huge fart erupted from that same huge butt, once again making Lillian burst out laughing but that laugh got cut short when the two of you saw that same tiny ant fall straight back down to the bench, lifelessly landing on its back. Clearly, it had been fumigated.

"O-Oh" Miriam was normally nonchalant about her farts, but she also saw the ant land on the bench, clearly it fell from her butt, blasted out by that big fart and it was evidently dead. It didn't take a genius to figure out why, and that conclusion is what got her blushing in embarrassment.

"Wow mom, you farted that ant to death" You said, eliciting Lillian to laugh more. Miriam blushed even harder.

"C-C'mon, sweetie... that was an accident" She sounded apologetic, genuinely feeling bad for the innocent life she ended regardless of how tiny it was. She gently picked the ant up and dropped it somewhere nearby on the soil, a reasonable pseudo burial in her view, allowing the body to return to the earth.
"That poor thing didn't deserve to die like that" Miriam sighed and sat back down. You hugged her belly to comfort her, knowing she disliked having things like that to happen. Meanwhile, Lillian took a good two minutes to finally stop laughing...

"Goddammit, why am I not getting any mercy, when even an ant would have?!" You muttered, facepalming as that memory finished playing in your head. Your mom took no joy in harming small things like that, yet she was gleefully letting loose massive blasts all over your equally tiny self.

On the other hand, at least your mom cared back then. When you were with Sheila, she was far more quirky and playful like her daughter, and in situations like that, which did happen a bunch of times, the big Brazilian beauty was happy to sent the unfortunate bug flying with the biggest fart she could muster. And the times you were with Dolores, her gigantic booty was so massive that almost every single one got squashed into oblivion, though there was that one unlucky ladybug that fell into her crack and it was either crushed between those meaty moons or it was blown to smithereens by the giant fart she ripped shortly after.

"That was a pretty big one!" Caren giggled.

"Yeah, you're right" Miriam chuckled "I've been holding a lot in during the day... Do you think it was too much?" She then asked with a hint of worry.

She knew that Caren's shrinking ability made you extra durable to the point that her 'fun' was harmless, something that Caren demonstrated extensively, even using herself as an example, having volunteered a few times to let Miriam test herself that her big butt wouldn't crush a shrunken person, or that her big farts wouldn't fumigate them like the unlucky bugs she did in the past.

"That depends" Caren shrugged "Would you have ripped that one on him at normal size?" She asked cheekily.

"Oh for sure!" Miriam giggled, answering without missing a beat "Maybe that one would've been a bit much to let out in his face, but I do enjoy sitting on his lap and 'unwinding', if you catch my drift" She said and the two giggled some more.

'Wow, this guy is one of the luckiest on Earth and he doesn't even know it' Caren thought as she blushed, her own horniness was skyrocketing. But she wanted to keep messing with you and it was a perfect chance to add fuel to the fire.

"I guess that explains it" She said, trying to sound intentionally cryptic, which Miriam immediately caught on, raising an eyebrow and prompting her to elaborate "He said he was used to it when I warned him about you gassing him while shrunken" She added and then stood up and walked towards her to whisper in her ear.
"He was too embarrassed to tell you himself, but he asked me to tell you that he really doesn't mind. I could tell he really meant that he wants his sweet mom to feel better and not get a tummyache"

"Awww, that's so sweet!" Miriam smiled "I always knew he was just pretending whenever I've given him my own brand of motherly love" She whispered back "After all, he always stayed with me even if we were watching a movie or some series, no matter how gassy I got. He also never really minded it when I asked him to give me a tummy rub while having an upset belly"

Caren's pretty, usually pale face was getting much closer to a full on beet red blush as she heard these things, picturing a fairly accurate version of those scenarios happening. At the same time, she felt somewhat annoyed at all those missed opportunities to let you feel all that at a size as small as your current one, and even more so at all the missed chances to huff all those hot gases herself.

"Well, I'm glad" Miriam smiled, looking down at her gurgling belly, gently caressing it and easing more gas bubbles along. They were big, even for her, but then again she was the one wanted to try the new triple refried bean burritos at the Salsa Shack after a pretty redhead that worked there told her about it.
"It does feel better to let them out with my baby back there" She confessed with a guilty giggle "I think I'm gonna have to ask you to teach me how to shrink stuff myself" She joked...
