"WHAT?" Alex replied in disbelief. Sure she had been crushed under this girl's feet more times than she cared to name, but being pinned under her enormous posterior would certainly be a new experience. Not to mention that Saturday was being awfully forward about her intentions. Usually she at least pretended what she did was an accident.
"Yeah I was just thinking 'If Alex feels so good under my feet, she would probably feel great under my butt too!'" Saturday replied, grinning from ear to ear.
Alex could hardly believe how casually this girl was talking about crushing her beneath her butt. Alex knew she was powerless to stop the girl from having her way with her, especially since Alex was already on the couch in the prime position to be sat on."Saturday please reconsider. You have no idea how unpleasant it is for me to get squished under you like that." Alex entreated, hoping to appeal to some sense of decency within the young girl.
Unfortunately, she had no such luck. "And you have no idea how good it feels to squish you! Besides, it's not like you actually get crushed. And who knows, you might even enjoy my butt!" Saturday replied, turning her back to the tiny girl, effectively ending the conversation.
Alex knew she had no chance of escape as the jean clad ass of the giant 13 year old came plummeting towards her. Resigned to her fate, she allowed herself to fall down onto her back, hoping at least to find the least unpleasant position to be squashed in. Being stepped on countless times had taught her that impacts that compress the spine vertically always proved more painful.
As Saturday's enormous posterior struck the tiny girl, she found herself pinned beneath the rough denim surface that covered the giant girl's right butt cheek. The material scratched her skin as Saturday slid into place on top of her, giving her a number of small cuts and bruises but as always doing no permanent damage. From Alex's tiny perspective, every tiny movement and shift of Saturday's weight was like an earthquake.
"Come on Alex I can barely even feel you under there! You're supposed to make my seat comfier!" Saturday squealed, impatient. She began to lightly bounce in her seat on top of the girl, trying to motivate the girl to be "comfy" for her, as though that were something Alex could consciously decide to do.
For Alex, this bouncing was analogous to being struck by a meteor over and over again, as though some sick being were rewinding the scene and playing it over and over for their twisted amusement. However, just as the bouncing was beginning to become routine (though still just as painful as the first blow), it finally stopped. As Alex lay in the ass shaped crater, barely visible to the average person, Saturday got up and looked down at her.
"Damn it Alex I can't even feel you under me." Saturday whined. Alex breathed a quiet sigh of relief, happy that Saturday didn't seem to enjoy keeping her under her butt. Any relief she felt instantly subsided as she realized that the giant girl was now working her jeans and panties down her legs.
"What are you doing?!" Alex screamed, though she had a feeling she knew exactly what the giant girl planned.
"I think my pants are getting in the way of me feeling you. I bet you'll feel way better against my bare butt!" Saturday explained before leaping into the air, sending her butt plummeting down towards her neighbor at breakneck speeds.
In seconds Alex once again found herself crushed the mammoth cheek of her cruel neighbor, though now there was nothing separating her from the warm doughy flesh of her ass. Without the jeans to constrict it, Saturday's flesh seemed to flow around Alex's tiny body, forming a vacuum seal of sorts around the tiny girl. Luckily, she needed very little oxygen at her tiny size.
"Ahhhh.... much better." Saturday sighed, twisting her butt on the tiny girl to maximize the pleasure she derived from feeling the tiny form wriggling beneath her.
While no longer being scratched by denim, Alex now had to deal with the oppressing warmth from the girl's body heat, making her feel like she was in a panini press. And from the sound of Saturday's words, it seemed like this was going to become a regular occurrence.
Alex had no idea how long she spent under Saturday's butt, but when Saturday finally stood up Alex found herself going with her. Heat and pressure had adhered her to the enormous buttock, preventing her from escape. At the very least, she was happy to have the unbearable pressure of being sat on relieved.
Saturday burst out laughing upon realizing that Alex was stuck to her butt. She almost looked like a tiny star fish stuck spread eagle to her mountainous ass. "Seems like you're enjoying yourself." Saturday snicked. "Well, I wouldn't want to interrupt you. Feel free to hug my butt for as long as you want."
Alex wasn't quite sure what this meant, though it became apparent as an enormous shadow slowly enveloped her. Looking over her shoulder, she saw the enormous wall of Saturday's panties rising behind her.
"Saturday don't you da-"
SNAP!
Alex was cut off as Saturday released her panties, allowing them to snap against her ass and knock the wind out of Alex. While it still wasn't quite as bad as being sat on, the pressure of the panties on her back was immense, keeping her face pressed into the seemingly never ending booty. An extra few pascals of pressure were added as she pulled her tight jeans up over her ass again, laughing all the while. Satisfied with her toy neighbor's position, she began to address her.
"Well Alex I have to say I think this may be my new favorite place to keep you." Saturday taunted, patting the tiny speck through her jeans, focusing on the near imperceptible form squirming for freedom. "Anyway, I hope you won't mind....
