I got the front seat! That's so funny! We should play a game since we are on a really long road trip. How about truth or dare? I'll go first! Truth or dare? Truth? Have you ever looked at my boobs? Tell the truth. No? Yes, you have. It's not weird either. Look. I'll show you. Now you've seen your sisters boobs! Now it's my turn. I choose truth. Have I ever looked at your dick? I mean, yeah. How could I not? Okay, your turn. Truth or dare? Dare? I dare you to stroke your cock and cum for me before we get there! Cum for your sister!
