Wait Until You Have To Pee Again
From Thread 1
Your sister walks into the kitchen and you hide the balloon behind your back. She looks like she's had a hard day and she just walks on by you. You watch her leave, then you have to pee again.
4 Minutes later you're done with the longest pee of your life and your balloon is full.
You look into your sister's room and you see she's watching TV.
