A teacher stops her

When Becky got to the bathroom, her hopes of being able to shit vanished. There was a teacher outside the bathroom.

—Young lady, what are you doing here? The talk is not over yet.

—I know, but I need to use the bathroom. It is urgent.

—Did you get your period?

—No, I just...

—Then no.

—But, teacher, it's urgent, seriously.

—Unless you get a pass, or in your case, your period has arrived, I can't let you in.

Becky felt a silent fart slip out of her anus, and she squeezed as much as she could.

—But...

—And for escaping the talk, I'll make sure you clean up the auditorium when the talk is over.

—What?! But, but...

—No buts, go back to the auditorium, now.

—Yes, miss.

Becky had no choice but to return to the auditorium.
