The device is a sealed cage, slightly smaller then a phone booth, made with plexiglass on all sides.
The first time (there would be repeats with less struggling), I had to force her into the near door (most apparatus temporarily removed).
I catch her unaware as she is doing dishes. She hasn't had sex for several days so she is extremely horny, turned on even more because she is expecting something from me, but what?
I put handcuffs on her wrists, often a prelude to "bedroom bondage". Leading her by the handcuff chain, we head for the basement, not too uncommon for us. She becomes more and more afraid as she sees the cage and I pull her closer to it. She begins resisting, growing to full refusal and "dragging her feet" to avoid what she now knows I have in mind.
The handcuffs force her to comply. As I pull the chain leading her, she has the choice to resist and bare the pain as the cuffs dig into her or follow my lead.
She had no idea what was in store for her. She fought with all her strength, begging, crying a little as she is being put inside.
Inside, cuffs are attached to the top. I wrestle her ankle to the side where it is strapped in. The other foot follows and finds its place.
Although still struggling and pleading, she is secure enough to disrobe her. I fetch my hunting knife, razor sharp beyond the definition as she watches in disbelief and horror while I shred and remove everything from her.
Now standing nude before me, her hands, one at a time, are released, brought to her waist, and re-restrained to the side of the cage. Additional straps are installed, holding her, supporting her, restraining her, but allowing her movement in the small prison. Patches and tape to her eyes, earphones in her ears, she is slowly being cut off from the outside. A few straps also aid her in standing, so she won't get tired too quickly. The tiny earphones allow recorded instructions to be given to her without her hearing anything else.
Around her head are a dildo, ball gag, water dispenser, and food dispenser.
Between her legs is a wheel that allows either a butterfly vibrator, vibrating dildo, or a large vibrating dildo to be positioned just at her slit. Another similar wheel is behind her, containing a thin vibrating dildo and a small vibrating butt plug. She is well greased with a lube that doesn't evaporate.
Near her breasts are mechanical hands that can squeeze and fondle her breasts and nipples. Another set of hands can do the same with the cheeks of her ass.
Various paddles and whips are all around her. They are electrically controlled and can whip her very hard or fairly gently, depending on the voltage level.
She is inside, captive, unable to see or smell and can only hear what the machine tells you to do.
