Sorry for taking so long.
It got quite lengthy, so I’m posting it for now.
There aren’t any LoRAs for situations like this, so most of it was hand-drawn.
(I had AI help with things like correcting inconsistencies in the hand-drawn parts and refining shadows and highlights.)
It was quite a lot of work, so if it gets a good number of likes, I might make a continuation…
① Prepare a girl.
Get a healthy and flexible girl ready for the game.
② Have her wear a dress shirt.
Choose a dress shirt that fits snugly to her body. Picking the right size is a key point of the game.
③ Inflate the girl.
Gently inflate her by pumping air in through her backside until the fabric stretches taut. While inflating, encourage the girl to stay relaxed.
④ Make the buttons pop.
Pump in more air, causing the buttons on the dress shirt to burst off with force. However, if the girl bursts before the buttons fly off, you are disqualified.
⑤ Measure the distance.
Measure the distance of the button that flew the farthest.
The owner of the girl whose button travels the farthest is declared the winner.
“S-Senpai… what is this…?”
“Yup, the dress shirt fits perfectly! Let’s aim for victory together, okay?”
Shukko shukko shukko… (pumping sound)
“Ughh… S-Senpai… this is… hard to bear…”
“The last girl burst before we could finish, but it looks like you’ll be fine this time.”
“B-Burst…? W-What do you mea—ughgaaah!!“
Shukko shukko shukko… (pumping sound)
“S-Senpai! M-my stomach is…!!”
“It’s fine, it’s fine. Did you know? A girl’s stomach inflates really easily.”
BATSUN!!! (button popping sound)
“Fwah!!”
“Hah… hah… hah… hah…”
“The record is 50cm. Dead last.”
“S-Senpai… y-your face… looks so scary… P-please… let me go…”
Shukko shukko shukko… (pumping sound)
“Senpai!? It’s already over, right!? Senpai!!”
