You've noticed your younger daughter often holds her pee and ends up pissing herself. She is definitely potty-trained tho, so what's happening?

You decide it's time to ask. She confesses: her older teenage sister told her about orgasms, and how they're "just like peeing" so she's trying to get one. You laugh, pat her head, how silly. Then you lead her to your room and start fingering her clit to teach her how to properly do it.
