This will be interesting. I don't plan on posting here much. Just something I'm doing for fun, not looking to find submissives or the like.

But please, feel free to respond. I might tease a little. If I like you.
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.

Remember dears, subtlety is for cowards.

Why are we dancing around what we want when you can simply take it, be it?

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

My interactions with you all have been... lacking.

Shall we change that?

Why yes, they consent. How kind of you to ask. Ignore the monotone manner of their speaking, the poor thing is just so tired.

I finally came up with a name for my headmates and I- the Sidereus System

It's a Latin word that means something that's full of stars or celestial bodies, which fits perfectly 💕

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.

in my mind: i need them fucking clueless. i want to twist their brain into a pretzel. they shouldn't even be speaking so much as listening and agreeing. i don't even know why they're still a person. i could fix this. i should fix this. i will-

verbally: yeah, i could imagine how you'd look drooling

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.

Staring is not only acceptable, it's mandatory.

Is it okay if I open up your head and carve in My name and title on the very core of your being?

Lovecraftian cryptid that can't be easily perceived by people, so in order to get their point across they mind jack some poor traveller and puppet their body and voice to speak their will

And ofc the puppet is still aware of everything thats happening, it just feels too good to resist the creature~

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...

I quite fancy this form. As close of a representation of how I'd choose to be if given the means.

Vanity is a virtue.

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.

Well, look at all of these new follows. Looking forward to sharing my little musings with you.

Fuck it. I'm a system.

I've known for a while, but it's been a lot more clear in the past few months. There's three of us, as far as I can tell. I've just really wanted to talk to others about it and tbh this shouldn't be something to hide.
So... is it better to post something that would weed out people I don't want to associate with, or risk drawing attention to myself in a vulnerable fashion while attempting to be more unapologetic about myself?
