My Mistress collared me recently. It's the first 24/7 collar I've ever worn for more than approximately two weeks. I'm SO excited!
I was collared just before this year started. It's steel, not aluminum, so it took some time to get used to. No, it's not THAT heavy, but I've not had a thick stainless steel band around my neck at all times before. I had tension headaches for a week.
Now I am quite accustomed to it. I still know it's there. It's a constant reminder that I belong to someone else... someone I trust and care for who looks after me. I am incredibly honored.
Here's a photo taken tonight. This was a piccy taken for my Mistress so she might see the blouse I just bought. It may be part of my cleaning uniform if she approves. Please forgive the poor lighting.
