You laugh

"Oh come on. I will beat you anyway, I don't need you to drop off. The fact is" you send him a cold smile "it will be even more fun when I'll crash you in the final."

"Oh really?" he says "you know what will happen? I will win and then make you my slut. And then maybe, just maybe, I will take you with me to space."

You also can play this game, you walk to him and sway your hips "be careful boy, or you'll be the one with a collar around his neck."

You both look at each other with determination in the eyes. The game is on.
