next time just go take a shit in her garbage can in her room to teach her a lesson 😂

I always wonder why people don't just go outside. But I'm in the country.

Are you sure sister was recording for Tik Tok and not “Only Fans” (selling **** pictures and videos of herself)? If it was a Tik Tok video I cannot imagine why sister would need to record it in a locked private room like a bathroom. Unless sister had locked the bathroom door, I cannot imagine soiling your pants instead of barging into the bathroom - So I assume sister had the door locked. I think there may be a bigger problem than the obvious one you noted - Especially if little sister is underage.

why not just knock and ask her to get out.. or get your own place.

really? (Unless you have stomach distress) you can't hold it for 2 hours? I have held it in for hours because I could never poop in public places. Still, she should have let you in.....

And you didn't bother to go elsewhere to find relief? ydi
