The author’s fetish for genital expansion is a niche genre, but he has put his heart and soul into screwing it in so that everyone will be satisfied.
When creating and processing the girls in the game, we keep in mind the following points:

“It’s expanded so much that it can’t go back to normal”
“It’s cute with its bulging belly”
“It’s sensitive because it has lots of piercings”
“It’s treated roughly because it’s considered a tool”
“It looks like it’s useful to everyone and feels good”
“It’s been left out in the open and is slightly dirty”
“The tool level has increased, so the size and capacity have increased! It fits comfortably in the hand”
“If the diameter is 20cm, then 3cm in height is 1 liter, and if the diameter is 40cm, then 0.8cm in height is 1 liter”
We take care of them while thinking about things like these to make them cute and adorable.
