[ The metal panels open up to produce metallic hands that grab just one of you by the jaw. Resisting it is futile - running away even moreso. With a great strength the hand squeezes down on your jaw, separate metal appendages hooking around your teeth to wrench your mouth open - it's like going to the dentist, but even more terrifying!
An oddly-shaped metal clamp with a twisting knob at the end starts being inserted into your mouth, with more metal appendages pinching your tongue to stay still - that's right, the clamp does look like it's shaped like a tongue, doesn't it?
A metal appendage twists the knob, and the clamp starts to tighten. Twist, twist, twist - it starts to seal, digging into the back of your mouth until the metal starts to cut in, and then it goes further. Twist, twist, twist. There's the taste of metal and - well, no, you can't taste blood without a tongue but you can imagine that the liquid in your mouth is probably blood.
Finally, the clamp shutters completely shut, metal hitting metal, and the metal appendages pull back to disappear into the metal panels, taking your tongue with it. ]
