THE CAMPFIRE 
MASTURBATION METHOD

DIFFICULTY = Intermediate
LUBRICATION = Recommended

This method is named for the imitation of how a stick can be used to start a campfire from the friction of rubbing sticks together. Just place the penis between both hands and move hands back and forth. It is good to begin this method before the penis is fully erect because it will allow the glans to roll between the hands. It causes intense stimulation and friction, so lubrication is recommended.

WARNING - If flatulence occurs, bodily gases and bowel vapors may ignite. 

This particular type of combustion can cause catastrophic damage to your home and your community.
