Cut a good-sized cucumber about 2" (5 cm) from the end, leaving you with a cross section at one of the wider parts. Then use a small spoon to scoop out the cucumber 4" to 5" (10 to 12 cm) deep. You can use a knife if necessary to help form the hole you are scooping. Don't cut yourself! You must be sure not to make the hole wider than the diameter of your penis – a tight fit is essential. After you have the right-size hole, place the cucumber on your penis. It should be tight enough to barely fit. You will notice a fair amount of suction if it is adequately tight. The inside of the cucumber naturally provides a good lubricant. Masturbate normally, moving the cucumber up and down your shaft.
WARM AS A CUCUMBER
Once you've hollowed out the cucumber, lightly boil or microwave it. This makes the flesh softer. Soak in cool water for a few minutes, and then heat it up under running warm water. Dry it, poke an air hole in the end, wrap it with duct tape for strength, lubricate it (optional), and have fun. You can also rotate the cucumber between your palms to spin yourself to ecstasy!
