...

Some time ago, Fontaine introduced a new law, according to which every lady at a tea party must wear a diaper. There were rumors among the townspeople that Furina was involved in the fact that this law was approved so that no one could guess her secret desires. But it was just a rumor! And you weren't the one who believed in rumors without proof! Especially now. When you were invited to a meeting by lady Furina herself!

...

"Ohhh, darling, look at you! You're not ready for our tea party at all!"

Furina said this almost crying out in mock surprise. She was already wearing a thick diaper instead of her usual shorts.

Furina has approached you.

"Darling, let me help you with this little misunderstanding!"

Her hands rested imperceptibly on your buttocks to make sure you weren't wearing a diaper.
