Briefly, Tragos thought about what might happen if they did crash. Ares wouldn't forgive him for not being the driver. Also, for making his daughter squirm in her seat like she was, that too. Crashing was not the most dangerous thing that could happen right now, it was everything that came after that he should be worried about.
But it wasn't going to happen. It was far too easy to believe that it wasn't going to happen. The only bit of future Tragos really believed in right now was the future where he was going to move his fingers in tight circles around her clit, glancing over at her face when he curled two fingers up inside her, and the only thing that was going to happen were the noises she was trying and failing to hide.
