Alison has erotic dreams

As your driving you hear whimpering and moaning coming from the passenger seat. Alison is asleep still but it seems she's really enjoying her dream. You look away from the road and see two fingers disappear under her panties. She squirms left and right on the seat next to you as she touches herself. She begins to moan deeply thrusting up and down in a dreamlike state. You find a secluded place to park the car and watch her as she brings herself to orgasm. She smiles and after a few seconds, her eyes flutter open.

"What happened?"

"We..."

"I know that much, but where are we?"

"My car."

"Is anyone around?"

"No, Why?"

"Because I'm really horny."
