To cut the ends/tips of your pockets in your pants in order to have access to your cock. This affords you some access to your cock while in public, should you wish to masturbate. One needs only to put his hand(s) in his pocket(s) and reach in through the holes and jerk off or simply fondle oneself. This method is especially useful when one sees a sexy woman in public and does not wish to take a mental picture, right then and there, to masturbate to later. Instead, one can jerk off in this manner, right then and there, while looking at the woman in public.
Man, I saw that lady with the big tits at the store that you told me about. I was glad that I had access to the monster. My legs were all sticky after.
