It is the responsibility of the Dom to provide for the welfare of his/her sub, as he/she has trusted him to do. It is also the Dom's responsibility after the scene to help the sub to return to "vanilla space" after the scene. This entails providing both physical and emotional assurance to the sub, until he/she regains his/her sense of self, and is known as, "aftercare".
sub: "Sir? Sorry... i was gone for awhile. You know, in subspace. i'm so happy i made you happy. i'd really like to do that again sometime, if it pleases You".
Its also the most generic ship game ever.
Guy 2:Yeah, I played super smash bros brawl last week.
Guy 1:No, Continuum!
Best brought on by immense amounts of physical pain and weed.
Slave and Master must have a trusting relationship as a slave cannot enter subspace unless she gives herself completely to her Master. Master cannot bring this on himself.
When in subspace slave often feels connected with her master as if they are one and can have what can only be described as 'out of body experiences' sometimes accompanied by hallucinations. Slave may feel like she can read her Masters thoughts and he hers. This connection can last for days after the main experience and geographical distance does not always break the connection.
Master must ensure that his slave is cared for both physically, mentally and emotionally when leaving subspace behind. He must have intimate and extensive kowledge of his slave to ensure her wellbeing at all times as she will loose all sense of her surroundings.
Slave - you sent me to subspace, but i'm back now. Thank you
