Mmmmm...now let's do something different. Wet the palm of your stroking hand and, holding your cock nice and firm round the base with your other hand, rub the head of your cock with your palm in nice circles.
How does that feel boy? Keep going either until you've done 100 circles, or been palming for 2 minutes. Whichever you like - but I don't want to see that hand stop once.
What do you do if you lose track of time or forget how many circles you're at? Start again, at 0 seconds, 0 circles. *Giggles* I think you'll find you pay more attention the second time round.
