You are sitting on Zack's lap in the car. Your mom and Zack's mom decided to go on a trip and bring both of you too.

There was only 1 seat left at the back. So you need to sit on Zack's lap.

About 10 minutes into the ride. You feel uncomfortable and try to move.

"Sit fucking still" Zack whisper as he leans back.

"Uhm no" You whisper back and keep moving around.

"Stop" You feel him getting hard.
