Stiles knew his Jeep was old. Maybe he would go as far as to call it scrappy, but at least it stopped when you hit the brakes. And Stiles briefly rejoyced in that knowledge as a hand between his thighs caused him to do an emergency brake.

He looked up into Derek's eyes and as a mischievous grin spread across his face as their eyes locked and they both knew Scott and his meeting would have to wait.
