Time slowed to a crawl for the shrunken trio. Mark's mother returned to her cubicle, continuing her droning day of work. As she unknowingly sat upon her son and his friends they tried to find anything to pass the time.
“Have you ever heard of pinworms?” Tyler asked after a long silence. He was almost getting used to the heat and smell now, which almost made him feel more disgusted.
“What?” Mark asked back.
“Pinworms? Have you ever heard of 'em?”
“No.”
“They're like little parasitic worms that live in people's asses or some shit. I was just thinking how we're no better than those right now.”
“Gee, thanks. That's what I want to hear right now.”
Emily was still lodged halfway into the sweaty opening of Mary's anus. She tired herself out thrashing and screaming and had settled into just quietly murmuring into the sticky skin that surrounded her. She was terrified of inspiring Mrs. Robinson into clenching her rear again so she instead focused her energies on trying to remain as still as possible.
Mary leaned back in the chair, sighing. She looked at the clock. There was still about 30 more minutes until lunch time. She felt a familiar rising pressure in her lower abdomen. The older woman glanced around to make sure the coast was clear before discreetly leaning to the side a bit...
The anus suddenly bulged outward, shocking Emily with a new movement she had not felt yet. A loud rumbling sounded through the fleshy earth below and she trembled imagining what was coming next. The opening split open with a thick schluck right before her face and--
PPPSSHHHHHHHHHHHHHHHHHHHHHHH
Searing hot, thick winds rushed out of the pinhole past Emily's tiny form, the force pushing her head back and threatening to snap her neck. Particles of fecal matter that would never register to a normal-sized person splattered the poor girl's face and hair until she was coated almost entirely brown. The hole then suddenly closed up leaving Emily to cough and gag in the miasma. The smell was thick, ripe and oppressive. It ravaged Emily's senses, her nose burned and it felt like there were daggers in her eyes.
Mrs. Robinson just farted on me. Oh god. Oh god.
It was too much to think about. Emily felt her body convulse again, but there was nothing left in her stomach to puke up. She retched violently, each breath of the rank smog causing her to relive the nightmare all over again.
Mark and Tyler weren't doing much better. They had both finally lost their breakfasts as well. Sobbing and writhing in agony, they screamed for help, but no one could hear their cries. The flatulence was absorbed harmlessly into the seat cushion below.
Up above Mary mentally sighed in relief. No sound and no smell, the best outcome one could ask for.
Before long lunch time had arrived, and Mary's coworkers had swarmed around her cubicle without a moment to spare, Barb leading the pack. Mary gathered her things and the group prepared to depart for lunch, but before leaving the floor Mary detoured into the office bathroom.
Mark, Tyler and Emily all began to panic as they felt the lumbering movements of their oblivious tormentor. Their world heaved and swayed, each of the woman's hammering footsteps reverberating through the thick flab that surrounded them. As they endured the constant pounding, they heard the creaking sound of a door opening. The previously muted thuds of her shoes on carpet switched over to heels loudly clacking on tile. The three teens began to wordlessly panic as they assumed the worst was about to happen.
Mary locked the bathroom door before turning around and lowering her pants and underwear. Thoughtlessly, she bent down towards the awaiting toilet seat.
Mark grimaced as he felt the G-forces of her movements press his face deeper into the sweaty flab. He was only dimly aware of Tyler screaming beside him. It was the same terror they went through when she sat down in her office chair earlier but Mark knew what was coming now. He tried to deny it but when they heard the immense rustling and felt the rush and blinding light from her panties pulling down there was no other way to rationalize it.
Mary's rear struck the toilet with such force it violently tore all three shrunken teens from her body. Her massive buttcheeks wobbled and shook after the collision, knocking them about and guiding them downward. They screamed in animal panic at the looming waters below.
What happened next Mark wasn't quite sure how he accomplished. He managed to halt his descent by grabbing one of the fine hairs that lined the swampy sides of the living canyon they had spent the better part of the morning in. Then, with reflexes he only read about in stories managed to grab the falling Emily in his free arm. The impact of her body almost threw the two of them into the churning abyss below, but they managed to hold on by slamming their bodies into the blubbery side of his mom's asscheek.
The two hung from the hair, suspended over an ocean of toilet water, finally reunited.
“Mark... oh god, Mark...” Emily's voice was weak, and she sobbed into her boyfriend's chest. She was in a bad way. Completely coated in oils and excrement. Mark grimaced, imagining that he couldn't be looking (or smelling) much better. He focused on trying to calm her down.
“Hey I'm here too y'know!”
The couple looked up in surprise. Across the way, closer to the other side of the giant woman's ass half was Tyler, also dangling from a fine hair. Mark smiled, possibly for the first time today.
“Someone's looking out for us man!” he called to his friend.
“Yeah I think it's a bit premature to be celebrating dude,” Tyler snapped back. He then looked upward and began attempting to make contact with the massive being above.
“MRS. ROBINSON! DOWN HERE!!”
The others joined. “MRS. ROBINSON! DON'T DO ANYTHING, WE'RE DOWN HERE!” “MOM! HELP US!! WE'RE SHRUNK!!” “MRS. ROBINSON!!” “DOWN HERE!!! LOOK DOWN!!!”
The three screamed themselves hoarse, hoping they could be heard in the private silence of the bathroom. But it was futile. Their tiny voices faded away before they could even travel from below the woman's rear, much less making it all the way up to her eardrums.
The only response they received was a nonchalant sigh from above, heralding the arrival of a massive eruption of urine. It shot down into the waters below, deafening the tiny passengers with the loudest cacophony they've heard yet. Droplets of water and piss sprayed everywhere, and an acrid mist began to suffocate the tiny passengers. They choked on the harsh odor and struggled to hold on. As the unwitting giant urinated another fart nonchalantly spurted out of the anus above, adding to their torture.
Soon enough the stream of piss tampered off. Mary was relieved, she had been holding that in all morning. Her prisoners below were hyperventilating, praying that she had nothing else to produce. Mark gasped as her massive hand snaked down to their alcove, tissue clutched between her fingers.
For his own mental state's benefit Mark had done his best to try to push out the fact that the sights and sounds he had encountered thus far were coming from his own mother, but it was getting harder and harder to stave off the impending breakdown when he had a front row seat to watching the woman scrub her stadium-sized genitalia. Even closing his eyes was fruitless-- the sticky sounds of the grisly flesh being moved about was something he'd hear for the rest of his life.
Oblivious to her audience, Mary dropped the used tissue into the bowl below and flushed. The sound was so loud it threatened to blow out the eardrums of her tiny companions and all of them screamed over the maelstrom. With a loud huff the middle-aged woman began to pry her rear from the toilet seat.
Still reeling from the sound of the toilet's flush, the gravity shifting caught Tyler off guard.
“Mark! MARK! HEY!!!” he cried helplessly. Mark and Emily's eyes widened.
He began to slip.
Tyler shrieked in abject terror as he was torn from his lifeline and began freefalling out from the woman's behind. He could see the rising giantess' behind getting further and further away until-- SPLASH!
Tyler suddenly found himself underwater. He thrashed in all directions desperately, praying to any god that would listen that he was not where he thought he was. He broke the surface of this new ocean he found himself and coughed and sputtered.
"Help! Fuck!!"
Above and all around him were endless walls of porcelain stretching miles above. And outside those he could see Mrs. Robinson standing as tall as a mountain, just finishing pulling up her pants. It was hard to believe he fell from something so far away, but Tyler had no time to ponder that fact, as his worst nightmare was about to come true. Unless he got Mrs. Robinson's attention, he was about to be left to drown in a toilet bowl.
His frantic splashing and screaming were futile, Mary was of no mind to be looking out for the sounds of shrunken men in the bathroom. And even if she were, the sound of the refilling toilet effortlessly dwarfed any noise Tyler was capable of making. Paddling in the freezing water, Tyler watched in knowing despair as she began to move away from the toilet, dropping the seat down and plunging him into total darkness.
