First I need you to get a bowl of water and ice. Then you will stroke your dick fast but without a lubricant. I want your dick to be on fire. When you feel its hot you will put it into the bowl of icy water and cool it down. Then you have to start stroking again, make the dick hard and hot and when I say GO.... you know what to do;) We will do few rounds of hot and cold stroking game and in the end you will get a chance to cum. Well....if you make it on time, hahaha:D
