-Andrea-
Andrea was reading a book in her living room. She had just put up some groceries she'd bought from the store. As she read through her book, her stomach made an ominous grrrlllll noise that told her she might need a bathroom soon.
It's not that bad yet, I can wait. She thought, and marked her book before getting up to go finish the dishes she'd left soaking in the sink. Andrea scrubbed at a grease spot on a pot in the soapy water she'd left. She was almost done with the load of dishes when it happened again... grrrlllll!
Damn it, again?
She was starting to feel a bit of pressure in her gut, but she still brushed it off as trapped gas.
I probably just need to fart.
She continued with what she was doing and finished the load of dishes, and then went to go and tidy up some of the rooms in the house.
Andrea was busy tidying up one of the bedrooms, putting toys away, straightening up the covers on the beds, hanging up the clothes, then a loud gurgling in her lower gut and a strong pressure forced a wet shart out of her that smudged against the seat of her pants.
Plluurrff!
"Oh my God!" She exclaimed as she immediately clamped a hand to her ass, "Maybe I really do need to take a shit,"
Phlleeaarrgghh! Phlloorrpsshh!
"Oh shit!" She exclaimed, feeling another wet shart smush into her pants as she hurried off to the bathroom.
Dammit, I'm about to shit my pants.
She got to the bathroom, hurried over to the toilet and snatched her pants down. The second she sat down on the toilet, a violent wave of diarrhea sprayed out of her with multiple splutters.
Plurplurplurpleeaaarrrggghhh! Ssssshhhllleeeeaaarrggghhh! Plorplorplorplorplorrrrrgggghhh! Flllaaarrfffffttttt!
"Ngh, oh God," she groaned holding her stomach as it cramped up and sent another wave of diarrhea squirting out of her.
Splersplersplershphloooooorrrrrfffffftttttt! Flllleeaaarrrrggggg!
"Guh!" Andrea rested a hand against the wall next to the toilet while more diarrhea continued spraying out of her ass and splattered the toilet bowl.
Ploploploploploploploplop! Blrpblrpblrpblrpblrpblrpblrrrrrrrrppp! Fllluuuuuurrrrrsssshhhhploploploploploploplop!
By now, Andrea was gripping her stomach with both arms and a grimace completely painted her facial features.
"God what did I eat?" she groaned while another wave of solid lumps squeezed out of her ass and plopped into the bowl.
After about 5 minutes, things seemed to calm down and Andrea thought it was over, that was until she heard a loud gurgling and suddenly felt a strong cramp in her lower stomach.
Then, without warning, a large wave of sludgy diarrhea violently sprayed out of her ass and splattered the sides of the toilet bowl.
PLLLEEEEEAAAAARRRRRFFFFFFTTTTTT!
PLOPLOPLOPLOPLOPLOPLOPLOPLOPLOPLOPLOPLOP!
FLLLLLLAAAAAARRRPPPLOPLOPLOPLOPLOPLOP!
SHLEARSHLEARSHLEARSHHHHHHLOPSHLOPSHLOP!

Andrea's face contorted and she tightly held her stomach, while her ass erupted into the toilet bowl, "Ngh, gah!"
When the violent diarrhea wave finally stopped, Andrea was left panting slightly, and one of her hands was now pressed against the other wall that stood on the other side of the toilet.
"Ow my ass is sore from all that," she muttered to herself, "Whatever I ate, I just hope I don't eat it again, because damn that was rough."
Andrea grabbed some toilet paper and gently wiped herself before flushing the toilet and pulling her pants back on. She then washed her hands and went on with her day as normal.
