Yvie looked at her wife Harmony, clutching her hands tightly, with eyes as deep as oceans. They'd been preparing for this day for years -- their marriage was one thing. Weddings were conventional, socially acceptable, something couples were expected to have. Yvie and Harmony went through the motions, doing all the paperwork, preparations, and ceremonies they needed to do -- and then they were married.
    But they wanted something else. Something deeper. Harmony wanted to be brainwashed. She wanted to be completely owned by Yvie. From a glance, she already was. Harmony was bound to Yvie's demands whenever her Mistress wanted something. They were in the dynamic 24/7, with Harmony having as few limits as physically possible. Yvie owned her body and her life. Now, she wanted to own her mind too.
    Harmony had a special collar for play -- with trim faux fur, pearl studs and a leather exterior. But obviously Harmony could never wear it outside of play. This time, though, it would be different.
    "An eternity collar," Yvie said as she held out a titanium circular collar with a key in a very small hole. From a glance, it didn't look like it could ever be opened once it was put on. "Once it's on, it can never be taken off, save for surgery or other... extenuating circumstances," she explained. "And I'm going to hypnotize you that once this goes on you -- and is locked -- your mind will be mine too. You will drop at my command and immediately accept whatever triggers or suggestions I want you to have without hesitation."
    "Yes, Mistress," Harmony said lightly, her eyes teary from her adoration.
    "Let me ask you one more time, just to make sure," Yvie said, narrowing her eyes as she stared at her submissive intently. "You do want this, yeah? This is a commitment. Like a second, kinkier wedding. You want your mind, your brain, your soul... to belong to me?"
    Harmony didn't even have to think twice about it. "Yes," she pleaded. "I love you, Mistress. I want you to own every part of me."
    "And you will stand by me, even in pain or suffering, even during strife in our relationship?"
    "Yes."
    Yvie grinned. "Wonderful."
    She looped the collar around Harmony's neck, snapping it in place. She pulled the key out and put it in a special box -- the box Yvie used to first propose to Harmony. Harmony may have legally belonged to Yvie before then. But now, she was mentally bound to her as well.
    Yvie pulled Harmony's hair, and dropped her effortlessly. "I want you to know that now, you are completely mine. I can play with every part of you, including your brain. You belong to me. I own you. And your mind will feel obsessed with me, inclined to follow my beck and call. It will feel like... an addiction, to me. You won't feel the same without following my command. Do you accept these suggestions?"
    "Yes, Mistress."
    "Do you feel it, plaything? Do you feel yourself addicted to me? Do you feel the thought of being apart from me the same as being apart from breathing?"
    Harmony giggled breathily. "Yes, Mistress."
    "Good. It will last as long as you have this collar on. If we need to take it off -- for any reason -- I will make sure this conditioning stays in place, through sickness and conflict. Feel these suggestions, plaything. Feel them burn into your brain... and let me know once they're branded in there."
    It took a moment, about a minute of agonizing silence as the cogs in Harmony's head turned. Eventually, her mouth opened, and she spoke. "It's done, Mistress."
    Yvie kissed the top of Harmony's Mistress-obsessed head, the tip of her property's mind. "I love you so much."
    "I love you too," Harmony murmured softly, and it was entirely truthful.
