She's not made of water herself. She's more water than most creatures, but she still has a "skin."

Think of her as...a balloon. She can take in a lot of water and will expand as the volume increases. Too much water, and the membrane holding her together would burst from the strain.

As Dechidechi stated, though, gradual filling of water allows her to expand rather than completely burst. She can adjust herself and there's not as much strain.

Try filling a water balloon from different faucets at different water pressures. The drippy sink should allow the balloon to stretch far more before bursting (even though it will take MUCH longer to fill), unlike the water hose at full burst, which will make her pop at a smaller volume (but would fill her significantly faster).

Suu is basically like a cell; most cells explode when in a hypotonic environment. You can actually watch this happen with both single celled organims and body cells that don't have a cell wall if you're ever in proper lab conditions for such an experiment.
