I wanna buy Lui-chan's balls~~
It would be more fun to slowly snip the balls one by one, layer by layer, instead of snipping them off all at once.
First snip them vertically, then snip them horizontally half a centimeter at a time~~
Even better to threaten her that if she can't make herself cum while you are snipping the ball, you will also take her other ball, but if she manages to cum before you finish snipping off her ball, she can keep the remaining ball for now~~
She will be forced to try her best to masturbate and cum while enduring the most severe pain of getting her cute little ball cut into pieces~~
So cruel, but so sexy~~
