When my late slave-wife took hers, she vowed her "body, mind, and soul" into my perpetual care, keeping and use. I swore my perpetual care and keeping as her Master, so long as we both drew breath. She was kneeling, nude before me, and when we finished our vows, I fastened her collar around her throat. It was only removed for her medical care. To the world, her name remained Andrea, however, I renamed her One when she swore her vows.
I will register her for you, obtain her Slave Registration Number and Bar Code, you can have the tattoo done when you get her home. I assume you want her slave trained. If you want her renamed, you'll need to let me know what you want, if she is to be gifted to you.
