【OC合作】 大人的噗噗大慘事

Original story by Slnfinity

Shumiao-sensei yawned with her hand gently covering her mouth before lying down prone on the desk. Her voice silently groaned for a little.

“Worked late again last night, sensei? Coffee?”

Shumiao from behind, gently tapped her shoulder and handed the sensei a cup of coffee. The commander leaned onto Shumiao’s desk to check on her.

“Yeah…thanks. Especially when it’s so close to the end of the year, work just started to pile up…I wish-”

Their conversation was cut short when someone knocked on the office door. Two students peeked in from the slowly opened door and simultaneously called out to Shumiao and Tristania.

“Sensei!”

“Sen~sei.”

Serika and Ein were the ones outside, where they decided to greet their teachers before heading out.

“We’ll be heading to school now, and I’ll be showing Ein-chan around since I didn’t have any shifts at my part-time job today. We’ll come back later since we’re going to have some fun. Don’t worry about dinner for us, okay?”

Her cat ears twitched in excitement, for she had just met the new friend they had saved from an otherworldly peril a week earlier.

“That’s right! We also made you two lunches, so be sure to heat the food before eating later!”

“Hehe, enjoy your work and lunch sensei. When you’re free, let’s go do some shopping around~”

Ein added right after Serika’s remark before the two waved and left the office. Shumiao and Tristania could still hear their conversation as they were going.

“You sure are excited today, Serika~ I even heard you go nyan nyan in the showers just now.”

“H-hey! You promise to forget that! That’s embarrassing!”

Shumiao-sensei and Tristania never had a chance to say anything before the schoolgirls left quickly. Afterward, they only smiled at each other, seeing how well their students got along.

“Since when did the two of them get that close to each other?”

“Beats me. I’m guessing being first-years in their schools probably allowed them to find common ground.”

Agreeing with Tristania’s take, Shumiao nodded, took a few sips of her coffee, and immediately winced from its extreme bitterness. The fact that Tristania always takes her coffee black has completely gone over her head.

“Ugu…and since when have you become a sensei, too?”

Shumiao jokingly asked.

“Always has been, for those kids. Just… without that funny tablet, though.”

The two exchanged a brief chuckle before returning to their desk, starting their busy morning.

When afternoon came, Shumiao and Tristania had reheated the lunch Serika and Ein had left for them, but when they started eating it, they felt something was off.

“Tris? Is it me, or does it taste a bit sour…?”

“Hmm…I doubt the girls mess it up since they are quite the good cook…”

While the two still wondered what had gone wrong with the food, the cafeteria door slid open, and Kazusa walked in.

“Sensei, I’m bac- Ah!!! That’s… Sensei, stop eating that! Th-that bento was brought back by Snow White yesterday! I-I think she said she will bring that to Millennium for lunch…!”

With a loud gag, Shumiao and Tristania both tried to vomit the food they had eaten, but it was too late. Too late, especially for Shumiao, since she had finished everything.

“I...I knew it..! Even after I told her to rely more on me to prepare food for her… Haa…”

Tristania gave herself a facepalm while thinking how she should have realized it sooner.

“Forgive me, Shumiao-sensei. I should’ve noticed. I’m guessing Snow White mistakenly took the bento made by Serika and Ein. Leaving us with the one we just ate…”

“You’re always putting sensei in such a situation, shikikan!”

Tristania quickly apologized when she realized it was her fault, especially since Shumiao-sensei had a digestive issue. However, it seemed to everyone in the room that Kazusa did not accept her apology.

“It’s fine, it’s fine! It's not like it’s actually rotten food or anything too bad. I’m fine Kazusa, really! And, you don’t really have to apologize Tris, since I’m the one who finished everything.”

With both arms stretched out in a motion to ease the situation, Shumiao-sensei tried her hardest to calm the two down before Tristania and Kazusa would fight again.

“Hmph. I’ll go get some drinks for you, sensei. Do remember to let me know if you feel sick, alright?”

Kazusa politely reminded Shumiao before grabbing some warm water in the kitchen. The cat, of course, gave a stern stare in Tristania’s direction afterwards.

After a few hours…

“Phew…I'm glad we finished today’s work before nighttime! Everything done, Tris?”

Shumiao stretched herself and asked. Her back made some cracking noises, as they had remained seated all afternoon.

“Mine should be done too. Just to double-check and then sort them out. How do you feel? Are you fine after the lunch?”

“Hehe! No problem, no way my stomach’s gonna go wild after that litt-”

Before Shumiao could finish her sentence, a loud growl could be heard. Loud farts escaped her puckered hole, and a building ache slowly twisted her gutter.

“U-uugh…it hurts…my stomach…”

“This is bad, let’s get you to the bathroo- Hnngh…! You gotta be kidding me…”

When Tristania stood up to aid Shumiao, her stomach acted violently, causing her to immediately knelt down.

“You too?!”

Shumiao was surprised to see the commander with nerves and balls of steel fall from having a stomachache.

“Yes, me too…! Gotta get to the toilet now…”

“H-hey Tris, me too…y-you’ll have to let me go first…hnnngg~”

Focusing too much on her stomachache, Tristania forgot that there was only one toilet in the office.

“...Right…we only have one…Kuh! Sorry, Shumiao. I promise I will not abandon you if we’re ever in a life-threatening situation, but this is different. It’s going to be humiliating if I soiled myself here…!”

“H-HEY! Hnnnggg…! I-I’m the one having a serious problem here!”

The two mature women pressed their thighs together as they desperately fought for the first person to enter the toilet while clenching their asses tight to avoid any accidents from occurring under their skirts.

“Shumiao-sensei…I’m really at my limit…!”

“N-no no no…! Tris…I’m…I’m leaking…ahhh…~!”

The women were still halfway to the toilet, but a loud sound froze the two.

Prrrrrrrrttt…Brrraap…Splurt!

Tristania slowly turned towards Shumiao, who was behind her. The sensei grabbed onto her arm tightly while partially knelt. Her curve, well-defined ass shown through the outline of her tight skirt, slowly builds up a small bulge. An unpleasant smell slowly filled the air around them.

“O-Oi…Shumiao-sensei. Don’t tell me you…”

“S-shut up Tris, and yes…i-it’s leaking from the fart I unconsciously let out…Now, may I use the toilet first…?!”

“…Hell no! Since you’ve already shit yourself, I am still doing fine down there! I’m going to take a dump normally!”

Even though Shumiao was trying her best to drag Tristania back by preventing her from heading into the toilet herself, Tristania still powered through despite the troubles brewing in her stomach.

Which…doesn’t bode well for the women. Tristania could feel a wet and warm feeling from her puckered hole that was slowly giving up on her. Stains of brown could be seen slowly staining her plain white panties. While Shumiao has practically given up. Still holding onto Tristania’s arms, her grips tighten as lumps of smushed-up brown filth filled her leggings.

“Y-you have to let me go, Shumiao. It’s coming out for me too…!”

Shumiao did not respond, as she was in a limbo between pain and pleasure.

“Hnnng…aahhnnn…”

Unfortunately, even though Shumiao and Tristania made it to the toilet, not even one of them managed to pull down their undergarments. The only thing they managed to avoid was further staining their skirts as they started soiling and peeing themselves.

“...UWAAAAAAAAAAAAAAAAAAAAAAAHHHHH!”

The sudden screams of both women from the office notified Kazusa, who was spooked briefly before the cat rushed upstairs to investigate.

To her surprise or shock in this situation. Kazusa was dumbfounded by the scene unfolding in front of her. The two adults they trusted so much were soiling themselves in the toilet. Their cheeks were soaked in their tears, and their underwear with their uncontrollable filth that broke the dam. An unbearable smell would fill the air.

“K-Kazusa…d-don’t look at sensei now. Oh no…hnnnnn it’s still coming out…I can’t hold it in anymore…”

“Uwaahhh! I was so close…so close…guh…aah…”

Everything fell silent for quite some time, especially for Kazusa, who stood and stared at the situation unfolding before her. Little did she know, her focus was drawn to Shumiao, and she inexplicably felt a wee bit of excitement slowly building within her.

The accident Shumiao was going through, her facial expression of a sweet mixture of pain and pleasure, the red ring of fire that was pushed apart by the enormous amount of feces she was excreating. It practically caused a sensory overload for Kazusa, making her bottoms gradually wetter the longer she watched.

…And the fact that she also saw Tristania’s secret.

Later, the three kept quiet, blushing with embarrassment, and worked together to clean the toilet, which was contaminated with nauseating filth and suffocating putrid smells.

Luckily, no one else living at the Schale quarters would learn of this incident as they decided among themselves that it would be their secret, which they’d take to their
