What is this?

D/s is living for the pleasure of the Goddess you worship, adore, and cherish with all your heart.  She using all the powers in Her arsenal to strip you of your ego so that the only thing you can think of is Her and pleasing her.  

For Her to be such a part of your pathetic existence that you wake, think and dream of nothing but Her, the Goddess you adore.

your goal is to become an extension of Her whim and live for Her happiness knowing that your only reward is Her pleasure.

male ego = stripped away completely

male desire = so totally consumed by Her that pleasing Mistress is the only important thing in the world
