Triple Hex
One of me was already too much for your weak little mind, now there are three.
Don't adjust your screen, pet. You're seeing perfectly clearly. Three Mxtresses, mirrored and multiplied, surrounding you on every side. Wherever you look, I'm there smirking, watching, waiting. There is no escape from this hex. There never was.
From the moment the spell takes hold, your eyes will flick helplessly between the three of me. Which one do you focus on? Which one is real? It doesn't matter. They're all me, and I'm all inside your head now. Every whisper comes at you from three directions at once, layering over each other, echoing, compounding until you can't tell where one command ends and the next begins.
Three sets of curves. Three pairs of cruel, knowing eyes. Three voices telling you to stroke... Then to stop. When one of me commands you to edge, the other two whisper that you don't deserve it. When one of me denies you, the others laugh. You'll be pulled in three directions at once, overwhelmed, overstimulated, and utterly helpless a fly caught in a web with three spiders, each one more amused by your suffering than the last.
By the end of this hex, you won't remember your own name. You'll only know three truths: you're weak, you're mine, and you're not coming until I say so.
