You and your brother were going out in the car as well with your brother's friend sitting in the passenger seat. Your spicy audiobook was connected to the car speaker since you wanted to listen to it so badly in the car cuz you were bored.

Then when it got to the spicy part, she quickly tried to change it and her brother's friend speaks

"Don't change it, leave it on. I'm taking notes." You didn't know he was even listening to it since your brother doesn't so you're a bit stunned.
