『Reverse Thrust Tenko』
A Man gives a Reimu and Marisa pair a bunch of candies, and the family has Munch Munch Happiness, and then they order the man that they want cake next time, with the man saying "I'll think about it" and going away without making a face, with his eyes as dark as onyx.
The Reimari family began to sweat, soon, they start wanting to go poo-poo, but try to handle themselves and end up eating all of the candy while coping with the pain; but the father Marisa couldn't handle it anymore, and suddenly excreted all of his pastes.
Reimu screamed, Her Anyaru also screamed, "Oofu!"; Reimu flew through the air, scattering her poop and her poop-like life as well.
Reimu's remains fall on the Man, he is in shock, but then stands up and starts walking out of the park
"Hold on. Mister!"
A peach hat with a gold badge, clothes with fluttering decorations, blue hair, a small body like a toddler... Yukkuri Tenko was standing in front of the man.
"Mister. Please, give me that medicine." Tenko begged the serious-looking man.
Then Mister smiled and gave her a bag, told her to "Be careful with the portion size" and walked away.
This Tenko, despite being a Gold Badge and raised with a caring Owner (No Abuse or Hentai), she can't repress her masochistic side when his Owner isn't looking. [...]
And since his Owner is at a relative's home, she came to the park to "Hold it until her limit" and when she saw what happened with Reimu, she was inspired.
Tenko immediately took a laxative., it was quite a lot, but Tenko would not compromise. She drank it all.
A strong bowel movement hit Tenko. A Danjiri festival began in her stomach. [...]
The urge to defecate had exceeded her expectations.
"So much...so much...ugh...ahh..."
She couldn't get her words out.
Her head was in a climax while her stomach was in a crisis.
Tenko decided that it was time to let it out, and headed for the restroom in the park.
Tenko is a Gold Badge and proud of it.
That's why she can't imagine letting it out in the open like a stray. [...]
Dripping with sweat, she finally arrived at the restroom.
There was a sign on the toilet that read "Out of Order due to Malfunction."
Tenko's long battle had just begun.
After seeing the toilet sign in the park, Tenko made up her mind and decided to go home.
"It's okay. I'll make it. I'll make it in time."
She has some regrets, but she picks herself up and takes it step by step.
Sometimes big waves would occur in her stomach.
If she's swallowed by them, it's the end of the world.
She gnashed her teeth and started walking slowly.
"Usually, the house is just a ten minute walk away, but now it's incredibly far away."
"It's gonna come out!"
While Tenko was groaning as she walked along the road, she saw a Stray Reimu.
Reimu smiles and said
"Cute little Reimu is going to poo poo. You can eat it. It's a special food!" while yelling out loudly, she took it out on the side of the road. [...]
Tenko felt sparks fly in her head.
Then she picked up the pebbles that were lying around, put them in Reimu's mouth, and hit her with a Russian hook.
The pebbles in Reimu's mouth shattered her teeth and ripped open the inside of her mouth.
Tenko hits Reimu in the face as she screams.
Tenko's heard a strange sound coming from inside her underwear.
Pushing Reimu out of consciousness as she convulses violently, Tenko decides to hurry her home.
"Haa... haa..." Her breathing was rough. She was close to her limit.
(Not yet... It's not time to panic yet.)
Tenko tried her best.
But sometimes from her underwear...
She heard a strange sound, but she ignored it and finally reached her home.
"Oh, Tenko, welcome home. This is my relative, Toshiaki, and this is Sanae-chan, who is Toshiaki's yukkuri."
Toshiaki (としあき) is the default and anonymous name on 2chan/Futaba
"I'm Sanae. Nice to meet you."
Toshiaki and Sanae followed her and talked to her.
Tenko smiled with a tight smile on her face and said
"Nice to meet you..."
Tenko barely replied.
"I'm not in the mood for this right now." she said.
"I was playing with Sanae like this. I'm sorry I haven't been playing much with you Tenko. All right then! Let's lift Tenko up high, too." his Mister replied happily
Tenko tried to escape. [...]
Tenko, who can hardly move anymore, is easily caught.
And then "Here we go! That's it!"
The older Mister picks up Tenko and throws her lightly upward.
It's like flying through the sky!
Tenko felt the greatest sense of freedom.
"Yunyaaaaah!" That's what it is!"
"Amazing! It's like a plastic bottle missile."
Tenko flew. Higher and higher.
Tenko flew. Scattering all kinds of things.
Tenko flew. Wishing to become a star.
After that, Tenko did not die because of her innate sturdiness and her large body.
However, she was scolded to death by his Owner.
And then, "Hey, hey, how did you do that?
Hey, hey, how did you fly through the air? Did you do that by yourself? Is it your hobby to bukkake on your Mister? Hey, hey? Please tell me. Why are you silent? Hey, hey..."
Everytime Sanae asks her a question, Tenko is silent with tears in her eyes and gnashing of teeth.
Sanae knows what she's doing and is asking the question on purpose. Sanae had an evil soul.
And so, because of her own foolish behavior, Tenko was teased by Toshiaki's ill-natured Sanae for a week until Toshiaki returned home.
