Your stomach is literally shrinking, tensing up like a knot in your abdominal. The machines poke at your lower ribs, and you feel another warm flush, not sure what it is. A thick, steel boned, lace corset is pulled around your waist, hydraulics twisting the laces slowly behind you as it is brought in tight. You watch your waist shrink with amazement, the lower ribs just gone or offering no resistance.
Air is pushed out of you, making breathing short and tight for a while, making you struggle to breathe through your nose. Your airways continue to clear, and your lungs relax to their new circumstances.
In the mirror you can see a perfect hourglass figure, almost cartoonishly enhanced by the corset. The crushing sensation of it is melting into waves of pleasure that pulse as you breathe, edging you again. You've heard of surgeries like this but are amazed at how well the experience plays in your mind. It all feels so real!
