Eye Contact Findom game

Let's play a little game... With your wallet. It's very simple. All you need to do is maintain eye contact with me. Everytime your eyes wander elsewhere, you must send me a tip. I decide how much the penalty is at any given time. Doesn't sound so hard, right? It's not, at first. But I'll be teasing you, more and more. My perfect curves in full view. You'll get to see absolutely everything, except... You're not allowed to look. Because if you look, you must pay. And who knows how much it'll cost you. $10, $20, $50.... or even $100?! Oof, that would hurt. Better stay focused on my eyes, then.
