"To keep the room clean," they say while releasing their load in the mouth.
The job of a cumbucket is simple. You are there to suck off some futa dicks and swallow their cum. Not allways an easy task considering how often your service is requested. You also might feel a bit stuffed sometimes, but one is not allowed to refuse to swallow the next load. It's an important job but theres not much to remember beside the salty taste.
