Mushy Brakes

76 CJ5 with manual drum brakes. The brakes have been needing adjustment, but working.
Yesterday, I was at a stop, pressing on the pedal a little harder than usual (for no real reason), when I felt it give a little. Not a big thing, just a little twitch.
Since then, the brakes have been really spongy. Interestingly, if I pump them a couple of times, they work better. Next stop, though, I have to pump again.
The lines are not leaking. I have not checked the reservoir yet, but I pumped the brakes multiple times in the driveway, and no fluid dripped from any wheel or anywhere else.
I am assuming that the piston seal inside the master cylinder either tore or otherwise moved out of position when I was pushing on the pedal. Does that make sense to y'all?
Other possibilities I should check?
