You managed to get your hand out from under his grasp from holding you down. You turn yourself over, and with your freed legs you kick him as hard as you can where you know it hurts. He yells out in pain and falls onto the ground. You get up, put your clothes back on, and spit on him. You walk out and run up the stairs. As you are trying to find the front door, you see something shiny on a table nearby. You casually walk toward the table to investigate. You see that there is a gun and car keys. You pick up the gun and check if it is loaded. You place the car keys in your pocket. You start to hear him fumble up the stairs. You turn around and see him in the doorway. You point the gun at his head. And you pull the trigger.
