For this task take the key to a set of hand cuffs and freeze it in an ice cube. When you are ready go into a dark quite room and strip naked. Put the cube of ice with the key in it in a bowel. Put on a blindfold and then cuff you're hands together in a way that you can get to the key to escape later. Lie down on the floor, put you hands above you're head and open you're legs up. As you lie on the ground naked, start to breathe slowly in though you're noise out though you're mouth. Some subs like to put there tongue so it touches there top row of teeth. While doing this let you're mind wonder and explore how it feels to be helpless, why it gains pleasure from serving others and slowly break down the wall to you're iner sub. At no stage touch you're self though the exercise. Try it once a week and see if anything changes. Etc how you act, think.
Time about a hour per session, Needed Handcuffs and Blindfold.
