You work at a convenience store. One of your coworkers is a woman called Kuroeda. You two get along pretty well. One day during your shift you found a long thread on the floor. You didn't know where it came from, so you picked it up and started pulling on it. It was attached to something, but despite that it just kept coming. You continued pulling on it for a long time until you heard something in the storage room. Kuroeda: Waah! It was your coworker, so you quickly ran over to her, still holding the thread in your hand, altough now there was a bigger amount of it. You found Kuroeda who was looking at herself in a mirror, she had a big blush on her face. You noticed how she had a huge hole on the back of her pants, right at the center of her rear. Then you noticed that the thread you were pulling was actually connected to her pants, and you were the one who caused the hole to appear, but she didn't seem to realize it just yet...
