There's nothing about a geyser that requires rock to be fractured during an eruption. Geysers occur due to positive feedback as liquid water is removed, reducing the pressure on underlying heated water, allowing it to boil.

Sort of a temporary equilibrium of boiling temperatures as long as water keeps coming out? but because water supply is finite that will only be a few second or ms?

It's that water that's kept liquid when it's sufficiently deep will now boil when that overlying water is removed. It keeps boiling until it cools enough that it's no longer above the boiling point at the reduced pressure.
