Sheila's planetary cheeks
You couldn't help you were standing on one of Sheila's ludicrously huge cheeks. Maintaining your footing proved to be a bit of a challenge though, as this was different even from when you had to stand on a bouncy house, this was more akin to a waterbed, but not quite the same. You tentatively took a few steps, then everything shook and you fell face-first onto the doughy surface.

"That tickled, sweetie!" Sheila laughed for a moment, then she slowly wiggled her hips, making her gigantic blubbery masses wobble in a way that'd be hypnotic for most men, but to you if was a combination of an earthquake and a series of tsunamis of fat and flesh.
"Please keep walking... It feels nice..." She said with a pleased sigh. Something about her voice made you gulp, but you decide to do as she said regardless. Just seeing how the massive fleshy globe stretched across all directions and into your horizon made you think that maybe even calling it 'planet-sized' was an understatement. You also shuddered at the thought of what would've happened if Sheila had decided to sit on you instead...

As you kept on walking, you sort of got used to how to keep your balance on the incredibly soft and squishy surface. Your legs felt shaky as the knowledge that this was definitely the biggest ass you'd ever faced in your life only made you blush uncomfortably. Your tiny steps indeed tickled Sheila despite her massive size compared to you, and somehow, it didn't feel quite the same as an ant crawling on her, and she could actually feel your two feet with little focusing on her part. She kept glancing down at her butt, barely making out the tiny speck on one of her jiggling cheeks, but she still found it cute in a way, although, it also seemed to awaken something else in her, and she started thinking of ways to keep you. She looked at you on her huge butt again and thought that maybe that should be enough for a good while.

The squishy 'ground' beneath your feet twitched lightly with each step you took, and every few ones, everything shook, which meant Sheila was tickled, and that same ground more or less became liquid-like as large waves rippled across it. Even after several minutes walking around her larger-than-planet-sized cheek, you felt like you had only advanced a couple of inches in real scale, but you were able to see to see a hint of its colossal twin in the distance. The ground shook again, but it felt different from when Sheila got tickled, and you heard a deep, distant rumbling from somewhere down below. A series of loud, gurgling groans were also heard, but they came from much higher up. You then heard her sigh in apparent discomfort.

After several more minutes, and more concerning rumbling and growling, Sheila decided that she'd rather lay than stand up as she had been doing so far.
"Hey, sweetie, I'm going back to my room... Hold on tight!" She said cheerfully and gave you a minute before she started walking. Like everything about her, overwhelming fell short of describing her, you actually grabbed two handfuls of her flesh and clung as tightly as you could, but nothing could prepare you for the insanely massive sense of motion as her gigantic cheek swayed from side to side, and in addition to that wobbled and jiggled every time her foot landed on the floor. It didn't take her long to reach the bedroom and she carefully laid on the bed on her stomach, though this too caused it to growl, seemingly angrily as if in protest.

"Done... I guessed it'd be a bit safer if I laid down instead of standing up" She explained and gave her hips a seductive wiggle, which was yet another series of quakes and rippling fleshy waves for you to deal with, but you weren't mad at those. And it was oddly arousing, but you felt kinda wrong about it, considering this is your mom's best friend, or the sister she didn't have, and yet, if was her who initiated this whole thing and sorta forced you to say that you liked her physique. You pondered on what else she could be possibly up to, but her personality was too unpredictable to tell for sure, so far, this was rather innocent, compared to other instances of her teasing you've experienced.

You continued to walk on the vast, jiggly 'planet' and soon you reached the massive canyon she called an asscrack. It definitely put the Grand Canyon to shame, and there was no way you'd make it to the other side unless you could somehow get a tiny plane. The low grumbling from the abyss' depths was much louder and it slightly shook the 'ground' under your feet, but Sheila didn't seem to notice, or if she did, she said nothing...

"Hmm, how about you try bouncing on my special 'trampolines'?" She asked with a smile, looking at you from over her shoulder. You looked at the humongous abyss below and gulped, then again, if you just get away from it you should be safe, so you walk a couple hundred meters in your scale before you give your first attempt at bouncing on her squishy flesh, a half-hearted jump, to 'test the waters', so to speak. You're surprised to find that you actually propelled yourself pretty high (again, in your scale) into the air, Sheila's fat cheek being a much power powerful trampoline than any you knew. Your landing was, of course, extra soft, and bounced rather high a few times before you landed for good. Your heart pounded from the adrenaline rush from the experience, and your previous concerns melted away... This was legitimately fun.

You felt safe, this reminded you of the many wholesome times you've had with her. Being the only 'aunt' you ever had, she actually spent quite a lot of time with you throughout your childhood and teen years. And despite not being on the same level of athleticism as your mom, she still made an honest effort to play sports with you and Lillian whenever she could. The funny thing was that, even with her dancer training, and sporting impressive strength, she had rather low stamina and tired out quickly, but she'd always spin it around to make it look like it was you kids who were tired, and she was just deciding on taking a break for everyone. This quickly became an open secret of sorts, and a recurring gag, if you want to put it that way. Many times you ended up just resting on the grass or under a tree, and your head was usually cushioned by her soft belly or lap.

"You see? There's a nice side to having a big auntie" She would say many times
"If I were pencil thin there'd be nothing soft for you to rest on" She also would add, either pressing you a little into her belly or giving you a hug and bringing you closer to her chest.


Even though sometimes it sounded like she may be ashamed of her physique, most of the time she was confident about it, and more often than not joked about it. She in particular liked to pretend not to notice you before she sat down on the couch, right on the part you were sitting on, but she always stopped before she did.

"Good thing I noticed you there! You need to be careful though hon" She'd usually say
"If I sat down, you'd become flat like a paper" She often joked , and that made her laugh some more
"Or maybe you'd get lost under there..."

She sometimes added, but it was all in good fun, and sometimes she'd reverse the joke by having you sit on her own lap, citing it as a much safer alternative. She always made you feel a little flustered, and thinking back on it, you wonder if she had anything to do with how your taste in women developed. Many would think anything resembling their mom would be an instant turn off, and while she was playful, 'Auntie Sheila' metaphorically (and literally, many times probably) took the cake.

"Ooh... That felt even better than your tiny footsteps... Do that again..." She said, snapping you out of your fond reminiscing, her voice unable to hide the pleasure she felt. Despite her massive size, her soft body, and specially her prized curves were fairly more sensitive than one would expect, and the extremely gentle touch of your near weightless body was sending mad shivers up and down her back. Feeling emboldened, you began to jump and giving them your all. In a way, it was like walking on the moon, but better, and with higher jumps you found you could more or less fly temporarily, and no matter where you landed you knew it was always soft. You could also hear Sheila sigh in pleasure and even purr somehow, but you didn't focus much on that, this was indeed really fun. To you, it was like you could jump hundreds of meters high, and even more in any direction. Tiny ripples wobbled their way across her blubbery globe as you kept jumping on it and bouncing. Strangely to you, her claim about her butt being amazing trampolines was indeed true, at least for someone of your current stature.

The thrill from this new experience, however, soon made you more and more confident, until perhaps you became too confident, but that's alright, isn't it? There's no way this can go wrong...
