Chapter #6Heavier Than She Looks by: NotOnTime   You didn't have any more time to waste. You had to run to the back of the chair, bolt there as fast as you could before your gigantic senpai squashed your tiny body like a bug. Her glorious panty-clad ass was coming down quick, the white fabric sky growing darker as its shadow fell on top of you. If you could just make it to the back of her chair in time you'd be in the safe zone, but it wasn't meant to be. Your tiny legs could only carry you so far, and even after hauling ass as fast as you could you only managed to move your position a few centimeters. At the last moment you spun around, to see your senpai's heavenly butt about to crush you. This was it-!!
----
Matsudo's skirt fluttered as she sat, drifting naturally over the edge of the chair. She was usually the kind of girl to tuck her skirt under her bum when she sat down, unless she was preoccupied with her experiments. Totally engrossed with entering the new data into the computer, her eyes were locked on the screen.
"Okay if I enter the variables right here..."
Her fingers clacked away on the keyboard. A few more seconds went by and she clicked her tongue again, disgruntled that her calculations had still yet to bear fruit. Why wasn't it working for her? She was going to keep at it until she figured it out.

SLAAMMM!!
The sound of your senpai simply sitting was an earsplitting affair. It was as if an entire skyscraper had toppled over, shaking the very foundation you had been standing on. You gritted your teeth, waiting for your sad, sudden, and pointless death, but by some miracle you had survived. The giant crushing force of you upperclassman's ass was flattening you into the chair, but you were still very much alive
"I... lived? I made it! I... ... ack! Senpai...! Your ass...! It's so heavy!"
The whole weight of her backside was bearing down on you. Not just that, but the upper body it was supporting too. You had been incredibly lucky, instead of being crushed into a fine red paste you managed to find yourself nestled in the small crevice between her two cheeks. It was the only spot that wasn't pressing flat into the chair, and offered you a tiny bit of breathing room. If she had sat even an inch from where she landed, you'd have been dead for sure. That said, the space between her massive globes was cramped as hell and the ever-present weight of her buttocks was barely pressing down on you to a non-lethal degree. It was hard to move your arms and legs and your chest definitely couldn't budge. Your back was to the chair meaning the front side of your face was being smothered by the weight of her ass.
You couldn't believe how big it was. It was a hard thing to wrap your head around, now that it was right on top of you. Matsudo-senpai had always had a small slender frame, she wasn't exactly well endowed or curvaceous, but she still had a wiggle to when she walked. Sometimes you would sneak a peak at her skirt, watch how it danced as she trotted properly down the school hallways. Daydreaming of how her bum looked under that skirt, you had no idea it would ever become this gargantuan. Her ass was huge and daunting, dwarfing your tiny body under it's volume. Just by it pressing against you, you felt a sense of how large and solid the rest of it really was. It felt like if you put your hand against the outer wall a building and pushed, the utter size of it was immovable. Her ass could easily have crushed the entire school with these proportions and leave it as a pile of dust when it rose back up.
Magnificent size aside, your female friends weight wasn't the only thing right now that was smothering you. A hot sultry blanket of smells were emanating from her ass crack, covering you in her scent and her warmth. It was amazing, the smell of her panties was so rich with feminine musk and pheromones that it made your head spin. You could smell the strong tangy odor of her crotch, the puffy mound that was just inches away from you let out a sweet sensual scent and it was driving your hormones wild. At the same time her ass and its dripping sweat were almost completely overwhelming their own fragrance. Your tiny lungs filled with the hot stuffy smell that came from between her butt cheeks. It was thick and heavy, concentrated with the earthy odors that had gathered inside her crack all day. The president was a clean girl, but to keep her butt from secreting sweat or other smells throughout the day was an impossible task.
The plentiful aroma soaked into your body, making you feel muggy and slow. Just the heat dripping inside her cheeks was exhausting you, and your sweat started to absorb into the giant panties and mix with hers. You were thrilled to smell such a private stench, to experience an intimate odor of hers without her knowing, but after a minute that thrill went away. The smell had begun to get to be too much for you and it wasn't going away, in fact it was getting hotter and stuffier as time went on. You were starting to drown in the heavy alluring musk of her ass, if this kept on for too long the lack of oxygen would be dangerous.
This was bad. It was either you found a way to escape from under her giant butt soon, or you might suffocate. Struggling wouldn't do you any good, her ass was too heavy to push away, even if you had a hundred copies of yourself. That, and exerting too much force would only waste the little air you had. Your only choice would be to wait this out, maybe she was only going to sit down for a few minutes...
...
A few minutes turned into twenty, and the president's gigantic ass was still sitting in its spot. Sure, she would shift and move around every now and then (causing you a great deal of crushing pain) but never once did her ass lift from the chair. She was still stuck the computer, typing away and working diligently on her calculations. It could be hours before she got up, time you didn't have. You were drenched in sweat at this point, gasping sharp breaths that were laced with her potent smells. It wasn't looking good, but it was about to get a whole lot worse.
It came suddenly. A harsh booming noise groaned up above, from somewhere deep within the schoolgirl's body. It was fierce and bellowing, so much so that it was hard to distinguish. The muffled roars echoed on for several seconds, sounding akin to ship's hull moaning against the ocean's waves. You had to brace yourself as the shockwaves came down to Matusdo senpai's ass, the vibrations were so large that they rumbled into the seat like an earthquake. The chair trembled beneath your stuffy prison, causing your body to shake directly against the sweltering panties. The frightening noise trailed off, leaving you to guess what had happened. Your answer came with senpai's mutterings.
"Ugh, I think something I ate's not sitting well with me..."
Her words echoed through her body almost as loudly as the previous noise did. You heard what she said, slightly muffled, but audible enough to get the terrifying message.
"No way... She couldn't actually have to...! There's no way! Senpai may be a bit odd but she's still a girl, she wouldn't actually do that right in the middle of the lab, would she?"
To your horror the groans grew louder, rumbling through the seat a second time. A massive load of pressurized air was gurgling through the giantesses' intestines, making its way lower and lower until... it would eventually come out as a fart. Her gargantuan body, the one that overpowered you by just sitting down, was preparing a release of monstrous proportions. If Senpai casually let a fart rip out her ass right now it would surely mean the death of you. The smell alone would be on a whole other level compared to the grueling fumes you were currently choking on. Even besides that, the impact was probably enough to kill you outright.
"Why..." you whined.
You knew why though. A memory flashed through your mind, of earlier that day. You had given your beloved senpai some chocolates as a treat, something you had hoped to make her smile. It was only until after she ate them with her usual demeanor that you saw the printing on the wrapper. The expiry date was for a week ago... and several years before that! The age-old chocolate must have been the cause of her body's discomfort, making her stomach churn and bubble angrily. Your gift had backfired in the worst way possible, with you on the literal tail end of it!
There was nothing you could do to stop what was about to happen. Her body was going to expel all this built-up pressure whether you liked it or not. Senpai's rumbling ass was now a force of nature, a great storm coming to tear you apart. Her cheeks had you pinned and you could barely move, escape was practically impossible at this point. You had to do something though! Before it was too late!   indicates the next chapter needs to be written. |
