Lily was just cooking some breakfast, minding their own business, when Magnolia interrupted them. She came up from behind them, turned off the stove mid-cooking, and lifted Lily's left arm. Lily froze in place. Not because it was a trigger or anything, but her sudden, possessive touch always put them in subspace.
    "I-is something wrong, Mistr--"
    "Don't interrupt me," Magnolia snapped as she began squeezing Lily's arm in various places. Lily flushed a deep red as her probing gropes slid up and down their arm. They couldn't figure out what in the world she was doing. But it was extremely hot. Eventually, she let go of their arm. Magnolia's eyes narrowed disapprovingly.
    "You haven't been working out as much," she noted with a tinge of frustration.
    Lily couldn't believe she figured out something like that -- and so easily, too! "H-how did you know?"
    Magnolia rolled her eyes, her expression growing in frustration. "Of course I can tell. It was one of the first things I noticed about you when I first got my hands on you. That you were strong, defined, and that your muscles now belong to me. Now look at you. What happened?"
    Lily looked down. This degradation felt more demanding, in a less fun way. "I just... fell out of the routine, I guess." They never even really thought about it too much. But now that they thought about it, it had been quite a while since they did their routine. Was their gear gathering dust, or something?
    Magnolia grabbed both sides of their cheeks, looking at them with impatient eyes. SLAP! Lily flinched but couldn't say they weren't expecting something similar.
    "You should know by now that you do everything for me. Including keeping your body in top shape. I told you you'd be keeping it up for me. Why do you disrespect me, plaything? Have I not set you straight you enough?"
    Lily wanted to make a joke about them being gay but they got the impression now wasn't the time. "I'm sorry, Mistress," they murmured. "I'll get back on it, I promise."
    Magnolia's frown turned upside down, in a wicked sense. "Oh, you will. Because I'll make it worth both our whiles."
    Before Lily could ask anymore questions, Magnolia held them in place by one shoulder, before taking out her pocket watch. She didn't even have to say anything else before they dropped into trance. "I want you to just think about it. Think of working out, of improving your body. For the sake of service. Service to me, specifically. You can focus your mind on that image... it feels so natural to you, after all. Doesn't it?"
    Lily tried to murmur out a 'yes, Mistress', but it came out like nothing more than incoherent muttering. "That's right," Magnolia cooed. "You're so focused on that image you can't even talk. While you're here, I want you to think of yourself. See yourself through a mirror... a mirror that's slowly but surely shifting. I'm going to put a new state of being in you.
    "Can you tell me, Lily, with words -- what do you think of when you hear the word 'himbo'?"
    Thinking came slowly, and it didn't come easily. They opened their mouth, trying to think through the fog clearly enough to speak. "S...someone masculine... who works out... and... isn't very smart... right, Mistress?"
    "Correct. See! You can think for me," Magnolia smiled, and Lily could feel it on their skin. "A himbo is someone strong, with enormous muscles. Someone soft and loving -- that's just like you, so we can just keep that in place. But the most important thing is that they're stupid. Not just ditzy and foggy like you, Lily, but stupid. All their brains go into working out and building their body, and they don't have to think about silly things like math or social skills or anything like that. They just have to focus their mind on working out. Just look at yourself in trance, and watch as you slowly find yourself becoming that himbo. Just slowly transforming. And every time I say the word 'himbo', that's who you're going to be. Nod if you accept this, Lily."
    Lily nodded, a slow and dumb smile crossing their face happily.
    "And whenever you're in this state, the further you are into your workout, the stupider you'll become. By the end of your workout, you'll be so dumb and stupid you'll barely be able to say an actual sentence. And then I'll give you a very nice reward, or mercilessly use your brainless body. Doesn't that sound fun?"
    Lily nodded again, letting out a stupid giggle.
    "Good. Then let's get to it, shall we?"
    She brought Lily up, and gave them no time to reorient from trance to the real world.
    It didn't take long after Magnolia used the new trigger word for the first time for Lily to get into their workout clothes and into Magnolia's in-home gym. Immediately, she started them off with push ups, with Magnolia's body sitting right on their back. Lily used to be able to do it with ease (partially because their Mistress loved the power rush so much), but after some deconditioning they had some difficulty. But with every push up, came a sweet reward. The loss of intelligence. It only took five or so push ups for them to start really feeling the intelligence draining. With every subsequent push up, it became more and more real.
    After three sets of twelve push ups, a two mile run on the treadmill, and more strength training exercises than the himbofied Lily could count... they were right where Magnolia wanted them to be. Kneeling from the fatigue in front of her, babbling out the dumbest sentences imaginable, and being more dim chuckles than breaths.
    "See? That wasn't so bad, was it, himbo?"
    The rush hit them once again. Lily chuckled thickly. "Um, yeah, it was so hot, Mistress."
    "Do you think you deserve a reward?"
    "Um... like, if you um, think I like, deserve one." That sentence took all of Lily's brainpower to force out.
    Magnolia grinned, beginning to unbuckle her belt. "I agree with you, himbo."
