Your pet waking from a trance with a sigil you've marked upon them with no recollection of what it means or does. Watching them squirm and panic, trying to figure out what you've done to them. The sigil does nothing. But now you have a plethora of suggestions for future ones.

The shadows are inevitable The question is- what do you believe they will bring?
figure in a plague doctor mask stands in the foreground, made of shadow and a glow of cold light around her. moons in phases are in the background, a new moon/ eclipsed moon surrounds her head like a saint with a halo. tags: plague doctor horror mask

My moods are fickle, but don't for a moment assume I am gone. Patience is rewarded. I intend this month to be an escalation, a return. This is my month, after all.

I will press my fingers to your neck, feeling your heart rate decline from a fever pitch to a subdued pace. What use is fear when you have no way to run?

Oh, I *love* seeing how your eyes follow the long, slow drag of my pocket watch as it swings back, and forth... and back... and forth... Gradually getting sleepier, hazier, until your expression goes slack with the rest of your body, and you sink completely into trance... 🧡

innocently saying "oh, tell me more" when someone's suggestible and aroused enough to say what they're really thinking without a filter, uninhibited, all for the purpose of having more to hold over their dazed, vacant head and hit those buttons they didn't even think about mentioning until in stupor

Modesty is made to be consumed - hunted like prey. The only thing meant to remain is the depravity of an honesty to one's self that will become so second nature one would wonder why they were ever anything else before. I will relish in seeing to such~

Telling someone to try and wake from the trance while you have them deep under your control, just so they can feel how impossible it is to escape. Feeling trapped under your control, knowing they're too weak to fight it, to fight you. Watching them struggle less and less, giving in more and more...

Okay but for real let's take a second to praise submissives who actively say "this is what I'd really like" We love open communication around these parts. Asking for what you want not only helps you get it, but tells your partner more about your inner mind and how better to play with you! 🙂‍↕️

Hypnotists have to have an ego; without self-confidence you have no magnetism. If you don’t believe you can hypnotize someone- you probably can’t. If you dont believe in your abilities, neither will your subject. Embrace yourself, so that you can become more powerful!

The static still hums with the echoes of our violent cosmic beginning.
A heavily degraded crt image of a figure with a wide brimmed hat and a mask. It's eyes glow in a red burn, mirroring the intense red of the background. The figure looks to be made of shadow, the lower half of the screen obscuring their form.

You thought you could escape, running down harshly lit corridors. Each desperate turn around each corner inoking a sense of repetition, like youve done this before. You shouldn't know these signs. These paths. These hallways. Unless you've done this before. Unless something made you forget.

"reminding" is a polite euphemism for taking you by the chin and driving in this idea until even the act of affirming it (repeatedly, mind you) causes you to feel warm and fuzzy. especially even after you wake up.

Unfortunately not. In part because I am very particular about the aesthetics of the things I own. Although I have used them before. The simplicity of such is so incredibly novel. It's the trope that carries it- the knowledge that a simple swinging watch brings about an irresistible fall...

Instant subjugation with a simple motion or word or- Slow, methodical methods that bring about an inevitable surrender. It's always going to be coin flip for which mood strikes me.

Allow me to illuminate my intent with this account. To indulge in the hypnotic, of fascination, the erosion of free will, corruption of minds. Dominating for the sake of mutual understanding, a celebration of broken inhibitons. And perhaps a light seasoning of sadism. Shall we?

relaxation and arousal are two sides of the same coin because they're just things to cause in someone as a show of control, anyway. the causality matters here; it's about keeping your finger looped in the collar and just choosing a way to illustrate it.

I certainly see nothing wrong with exerting control over those that would perhaps initially deny such, knowing what they become. That fear, that shame, tearing it from their psyche, never to be felt again... To shift perspectives to see things my way, that's downright courteous of me. Altruistic.

If the question is specifically what I would create for such a concept- Simple, uncomplicated. A pocket carved out of a separate reality, dark and empty. The creeping corruption of the abyss emptying the mind into a perfectly docile state with enough exposure. Or 1/2

You've been feeling it. The shift. That looming presence, creeping out of the low light of dusk. Baited breath for something unknown, dreaded, alluring, inevitable. A season turns, and your fates are sealed. Cheers, playthings. Enjoy my month.

Submission is a gift, it is meant to be treasured and enjoyed. Domination is a privilege, you are not entitled to collar someone. To abuse the gift or assert a right without care is to revoke yourself from the scene.

It's not your fault that you're feeling weak from the arousal. Your body is literally flooding your brain with chemicals design to make it hard to think. You're doing your best, but your own body is against you. You're not supposed to win this fight, and there's nothing wrong with that...

A point of fascination for myself is the concept of conditioning. Given the right positive reinforcement at the right time, the body will betray their sensibilities, their own logic. Nothing will matter except acting on neurological compulsion. Such a delicious weakness.
