Some people might think being a Dom mean's you always have the last word. Let's think about that for a second.
If you think telling her what to do is having the last word, I would argue you've missed something very important... Crucial even. Let's look at a scene, not for the scene, but for the pay off. No, not the orgasm, something much more profound. Something deeper than any orgasm and ultimately more fulfilling. I say, "Spread your legs." she says, "Yes, sir." .....did YOU see it. Maybe... but probably not. How about this...? You've just finished a fun scene... she says, "Thank you Master!" Did you hear it that time? Not sure? OK last chance... She's failed at something... it was TINY, it was nothing. You might even want to overlook it. But she looks at you with tears in her eyes and says, "I'm sorry Daddy."
She wasn't saying, "Yes, sir." She was saying, "I trust you and I give myself to you."
She didn't say, "Thank you Master!" She said, "I love you! I am yours."
She didn't mean, "I'm sorry Daddy." She meant, "I am yours and I NEED to please you. Please, help me be better. I will do better, I promise"
So the next time you give a command, order, task, etc. wait. Wait and see if you truly had the "last word". For if you did... you might want to ask yourself if your giving the correct first words.
Just rememebr, anyone can have the last word. Anyone can say the last word. You have to learn to hear the last word.
