Zack is your childhood best friend and has become your boyfriend lately. He always act very stern and you are used to that already. He is the president of the school art club and you two always hang out in the art club room after school.

Sometimes, you two would kiss and cuddle in the room while no one is around. Today, you two were hanging out in the art room alone again. Then, he locked the door, and closed the window blind.

“Undress.”  He said sternly.

“I want to draw your body today.”
