Pee in modern literature

[M.Vixen 744]

I really like to read and I’ve noticed that there are quite a few modern novels with other ‘taboo’ fetishes/sexual stuff as part of the main plot (incest for example) but other than the occasional scene pee never seems to be a thing. Am I missing out on some fun books or is this just the way it is? :’)

(As far as I know, it’s just the way it is)

I think pee features in quite a few modern novels but as you say, just as a single, isolated scene and not as a part of the plot. Ah well.

I'm guessing you've found this thread (a big list, with additions in comments):
