“Nemu, what’s the hold up?” Mayuri snaps, not even looking up from what he’s doing. Ever the good lab assistant, Nemu moves as quickly as she possibly can, but her creator, master, captain, and father- so many hats for one man, but at least he tends to wear hats well- is impatient with her by default. No matter how fast she is, she already knows that it isn’t going to be fast enough.
Today, she’s moving a bit slower than usual, though, because she has been denied any breaks. Whether this is an experiment of Mayuri’s, a sadistic flight of fancy, or even an unlikely oversight on his part, she does not know. The only thing she does know is that her bladder is quite full right now, and she is quickly nearing her limits. If she were to ask to be excused again, there is no doubt she would be denied.
So she bustles around his lab, ignoring the throb in her bladder, fetching anything that he needs, as fast as she is able to in her current condition. Of course, there is only so much that she can handle, and she was made with a bladder that functions the same as anyone else’s. This very well could be an experiment, just to see how long she can withstand all of this; for all she knows, Mayuri has recorded every variable, without her even noticing.
But, if that’s the case, the annoyed, almost tired look on his face when she does give in does a good job of hiding those intentions. As she stands before him, face expressionless though a bit flushed, piss running down her long, shapely legs, he lets out an exasperated sigh, before saying, “Don’t waste too much time cleaning up that mess, you stupid girl.”
