At first, start it by stroking your well-erected penis gently, tenderly with wet palms & then gradually increase the speed, force & power of the strokes.... go on & on & on enjoying the superb feeling...and just before you feel like orgasm, stop! STOP! Control yourself! Don't let it happen! Just stop!
Stay inactive for a while... then start it all over again! Then again STOP!
Repeat this ritual for at least three times! Then let it happen at last! Forget all controls, all worries and all tensions of the world! Just let it happen! Freely and spontaneously...And you will explode like a nuke bomb! You will come really big! Try it out and enjoy!
