A submissive's determination

The Master's call.

'Kitten?'
I call her from within my office. My hands continue to type out strings of words that flow into coherent sentences, creating tales of worlds far away. A small bell sounds across the hallway, sharper, louder, closer.
On all fours she enters the room, in her required outfit. Her head remains down. All instructions have been met. She crawls to beside my chair. Seated on her knees, looking down and hands placed on her thighs. With every movement her bell echoes amidst the room. The silver bell around a velvet ribbon. She wears it well.
'You called me, Master?'
She said with a smile. I finish my paragraph and turn towards her.
'I did, my dearest. There's something I wish to discuss with you.'
She nods attentively. I stand up and go to the bookshelf. THAT bookshelf. I pull at a specific book. "Wizard's first rule" By Terry Goodkind. My favorite book.
The bookshelf sways open to reveal our private room.

She knows there's only two reasons I want to enter this room. The first is to inflict punishment on her for being a bad pet.
She looks up at the opening and nods understanding, without fear in fact. She crawls inside.
The second reason for going there is that I want to inflict pain on her for my enjoyment.
That enjoyment usually led to... coital activities. Which she never really minded. Of course.
However this instance was led by neither of those two possibilities. Au contraire.

She sits knelt before the bed, unaware of what will happen, I'd say as usual but this situation even surprised me when it first came to birth in my mind. Upon long pondering as to how I'd do it, I figured it out to just about the last detail.
'Dearest kitten. We've been together for three years now haven't we? We've discussed getting married amongst other things, having a child...' She nods a bit confused. She's never heard this sort of talk in the private room...
'What is he thinking?' I'm sure is what fills her buzzing hive.

'I speak to you as your Master now. I wish to create a marital bond, with the nature of this part of our relationship. I wish to commence a collaring ceremony.'
She looks up at me with bewilderment. Her hazel eyes are transfixed on mine. Given the circumstances, I reply it with a chuckle.
'I must know whether you want this or not however.'

'I do, Sir!' She proclaims loud and proud.
I raise my eyebrow.
'I trust you. Words however, are just that; words.'
She nods understanding and looks down.

'I love you, Sir. I want to wear your collar. Your mark. I will not reside until I wear it.'
The confidence is noticeable in the smirk marking her lips. I grin.
'Face the bed. Place your hands on the end of it, palms down.'
She remains on her knees and does as instructed.
'You will only remove them when I return.' I leave the room and keep the door open.
