Rip her brown shorts off and assfuck her on the floor.

You rip her shorts and panties off and with a mighty thrust you penetrate her dry butthole. She screams in your hand and after a couple of more thrusts she faints from the pain.

You keep buttfucking her limp body. As you thrust away you can hear Emmy outside shouting for Michelle. You can see her through the cracks in the planks approaching the shack. She might have heard something.
