The black tank should empty faster than the gray tank. Gray uses 1.5 inch pipes, black uses 3 inch pipes. However, you may have had a wad of TP clog the valve opening. I agree with the previous posters that you should add water now to prevent all that mess from drying out.
Get to a dump station where you're not rushed. Fill the black tank with water (hose to the toilet or buckets of water), then open the valve again. More water volume should wash all the 'stuff' out. I would also recommend a clear sewer connection so you can see when you have clear (or almost clear) water running out of the tank.
