Let's play a game! When I say "green light", you can jerk your dick however you want! Fast or slow, it's totally up to you. But as soon as I say "red light", you have to immediately take your hands off your cock! Take them off and keep them off, until I say "green light" again. It's simple enough, but pay close attention -- I know you don't want to miss a second of stroking. To make it even easier to follow along, my lingerie changes color too!  At the end, I'll give you the green light to stroke uninterrupted one last time, and if you can make it and cum in time, then you get to cum today! If you don't cum before I say "red light" one last time, then you're stuck being blue balled today -- you'll have to try again next time! Good luck!
