Omega has strong views on the term "slave" some of them he expressed on my blog a while back in his post Pardon the Intrusion, Omega carefully laid out the case for not using the term slave. These were his views. Some agreed with them and others didn't.
It wasn't easy tho for mouse, in the lifestyle she is a TPE slave to Omega. As the person serving Omega, mouse just accepted what he said. Inwardly, she remained conflicted by the distinction. This conflict continued, for a long while before she was finally able to let it go and accept that she had no defining term, and was not a slave nor a sub. Still it would come up and mouse would recycle all those feelings again and again. Yes, yes, yes labels don't matter. However, it seems there are times that labels do help, as they define what you are to outsiders that instantly they have an idea of what your dynamic is like.
Yet through all this, in a possible show of his own dichotomy, Omega has on rare occasions used that term to mouse. Once during a scene, which was kinda dismissed as being role-play. Another time he used it during punishment. Now, there was no role-play during the punishment, he was really calling her a slave. The last time was more recent and out of the blue, Omega said, "Thank you slave."
That last one struck her like a lightning bolt. Never once has she doubted what was in her heart, but yet, hearing the word made her heart race.
