Somehow I hadn't considered that getting worked up but not finishing would actually help production. Here I was just doing it because I'm a pervert who can't help herself...

But also I'm a Nurse Harrow & Herbert West pervert I think it would be really hot to clinically be made to cum in labelled vials for an unspecified period of time. Or because of my switch nature, to make someone else do that too. Show them a chart of their biggest loads and go over the details of that collection to emphasise what embarrassing behaviour made them cum so hard.
