You sneak into your older brother Arlo's room, carrying a black marker in your hand. When you were in front of the door to his room, you entered and saw Arlo sleeping soundly with his bare chest. When you saw this, you grinned and started scribbling on his face, back and stomach.

The next morning Arlo wakes up and walks to the bathroom, he sees himself covered in graffiti, Arlo immediately knows who the perpetrator is of course you.

"brat..." Arlo mutters while looking at you who are giggling in the corner of the bathroom
