A tug-of-war between the Doctor and the Master.
You asked for a story prompt so how about this...Yuuri has just gotten his wisdom teeth pulled. Victor is driving his heavily medicated husband home afterword recording Yuuri's drugged ramblings for posterity and Phichit. (I am really curious what you are going to do with this. What does Yuuri with no filter talk about? Ha ha this should be fun.)
