You were at a party that Elsie hosted. Elsie was dancing until her stomach gurgled

Elsie: Uh, be right back!

she ran into her room and shut the door. You decided to follow her. You were outside her bedroom door, you could smell something, something smelly, it was coming from her room, you opened the door and saw her pooping in a diaper

Elsie: AHHH- Oh, h-hi...

she looked really embarrassed, trying to hide her diaper
