there needs to be a vaginal dildo that is articulated on the inside like a snake. So it can move and undulate in all kinds of patterns unlike anything we have today. If you google for “serpentine robot” you’ll see what I mean, but the dildo would be coated with a mesh sleeve and then a layer of silicone, so you'd never feel the internal joints. The main thing I want is for a locked-in dildo to be able to do the "come hither" motion as a wave pulse that moves from tip to base against the anterior vagina. But it could be programmed in any way at all. It could form itself into a corkscrew for drill fucking, or it could do rapid "tapping" against the G spot... anything.

So the outer silicone sheath has a small hole in the tip for it to push out lube continuously. pH-balanced, safe for vaginas. Might need to be configured to be really specific for the user, because we want this thing locked in 24-7. Yes, even during periods -- there could be a way to hygienically swap in pads without taking off the whole device, which stays locked on.

The dildo could be smooth, but I'd like it to be covered in soft bumps and ridges, especially against the G spot where they have their own internal vibrator. Also, it could be possible for it to do some small-amplitude fucking, say 1 inch in and out, but potentially extremely fast and hard.

So much for the interior. So the whole thing is like flexible metal panties, with a partial shield over the vulva. There should be soft, rubbery "fingertips" that spread open the labia, and another rubbery pad that can pull upwards on the top of the clit hood, so it's taut. A tube with a flexible ring opening slides over the clit itself and suctions it up into the tube. The flexible ring is important to help the suction work for all vulva shapes, and it can also vibrate, so that once the clit is sucked into the tube, the ring encircles it and vibes it.

Picture it like a tiny Venus 2000. A ribbed sheath inside massages the clit as it's rhythmically sucked. Inside the tube there is also a small spinning brush, ultra-fine and ultra-soft, which can spin at various speeds to either edge or tickle or excruciatingly polish the clit. The brush is kept soaked in lube that gets continuously replenished. The clit sheath also contains electrodes to deliver electric shocks to the clit, varying from tingling to painful (the latter during Punishment mode).

The labia are surrounded inside and outside with tiny feather-like labia ticklers, and another row of ticklers teases just inside the ass crack. An optional anal plug attachment goes inside, and a ring of ticklers teases the anus as it's stretched around the plug.

So there are all kinds of modes I think could exist. Edging: constant low-level simulation with occasional hard edges. Doesn't let you cum. Juicing: hard forced orgasms until it detects the pussy leaks and squirts enough volume of liquid (or the wearer pisses enough). Punishment: maximum overstimulation, forced orgasm hell, clit polishing and hard, fast fucking. Continuous orgasm mode: self explanatory.

Silence mode: a Bluetooth microphone peripheral detects any vocalizations and punishes the wearer for them.

CNC mode: the device downloads a program from a random internet user and executes it, also playing any audio that user included with the program.
