STOP! Take your hand of your cock. I lied. You don't get to cum yet. But you can watch cock #2 squirt his hot jizz all over my face.
You wish you could lick the cum off my face and chest don't you? Well, this cum is for me. But you look really thirsty so I'm going to let you have a little drink before we continue. You don't get to orgasm however. What I want you to do is stroke to the edge as many times as you can. I'm not going to force you to edge a certain amount of times but the more the better. Start stroking!
Every time you get to the edge I want you to get as close to cumming as possible. Tease the head if you have to. Stroke the tip with your fingers or grip it tightly to stay at the very brink. Keep doing this and pushing yourself as far as possible but back off before you feel like cumming. If you time it just right, you can stop the orgasm but still ejaculate. Cum should start seeping out while your cock stays hard. Your orgasm gets denied but at least you get a taste of that hot cum. You can even stroke it a bit to force more cum out. Make sure not to let any go to waste. Scoop up every drop and swallow it. How does it taste? Sweet? Salty? Bitter? If you've gotten this far then you can continue. But if you couldn't handle it and fully came, than leave now and come back in 1 week.
