Try to let some more out

You push again and manage to fairly easily let out a small spurt and then stop it. Apparently the few dribbles have loosened you up a bit. You let out a second spurt, but then panic floods through you as you find yourself unable to stop it. After an eternity that lasts but a few seconds, you manage to stop the flow but can feel the weakened floodgates straining to hold back the rest.
