As the capacitor discharges, the voltage falls. The charge Q = C x V, so the voltage V = Q/C falls as the charge flows out of the capacitor. This is true for any value of the discharge-circuit resistance: lower resistance makes the discharge current higher and therefore the time required to remove the charge faster.
