When Zipp happens to smell a smell one day, she decides there's only one thing to do: Investigate it. So she does.

Before long, Zipp traces the smell to its source. It turns out to be Sunny, who is most surprised and even a little bit terrified to be caught in the act of wearing a diaper.

But maybe Sunny just needs somepony to confide a little secret in. And perhaps, Zipp and Sunny will come to learn more about themselves and each other as they explore new boundries together.

Bonus: this is a collab with me and superpinkbrony12 he help me proof read my chapter and I helped him with his two chapters and he usually credit proofreaders and collaborators at the top of his story. https://www.fimfiction.net/user/22838/SuperPinkBrony12
