Ego Death
Ego death, as experienced by a slut, is a severe status condition many of us strive our entire lives to achieve. While it is merely a state of mind, it is regarded so highly that it can be thought as a kind of transcendence or an ascetic ascension in of itself. While it is often spoken of as though this is a permanent transformation, in truth it takes a great deal of will and proficiency to maintain indefinitely; many of us only achieve ego death in fleeting flickers of clarity.
In experiencing ego death, a slut completely loses subjective self-identity—even on the most fundamental physical level. Her underlying instincts themselves are reprogrammed to think of herself above all and before all as an extension of You. Your will (or what she perceives it to be) replaces her own. Your ego replaces her own. Your pleasure (or what she perceives it to be) is more gratifying to her than any pleasure she could ever hope to experience. She no longer even notices her own wants or needs unless doing so serves You.
At the highest echelons of true ego death, this becomes not merely metaphorical but absolute and true. Your thoughts and feelings cause the slut to act even more than her own consciousness, even if she otherwise has no apparent means of reading Your mind. She can even act in prescient anticipation of Your whims or wants before they even occur to You, without any conscious idea of what they are.
In typical slutspeak "ego death" implies a slut ascends to this state of mind without maintaining physical contact with You. In truth almost any slut who You've equipped experiences something akin to this mental state, at least as long as she remains so equipped.
