c# - How can I "squeeze" a game object when it is pressed between two others?

I am trying to "squeeze" a game object when it's pressed between two other objects (e.g., "squeezer 1" and "squeezer 2," below) that continue to move towards eachother.

I wish to reduce width of the object so that total area of the game object is maintained while still being between the two squeezers.

How can I achieve this effect?
