Try to exist

Haven't I already told you? Her dickmeat is in the way. You have just the barest amount of spirit due to this world's constraint's defining you as an entity. But in order for you to be a bespoke actualized thing, asserted against that which is around you, some definable space would need to not be categorized as your sister's penis.

And, even though this shouldn't need reiteration. There is literally nothing up for grabs.

Every single ripple in the void is either your sister or her cock, you cannot occupy space and call it your own.
