This is a rather unusual topic. However, in some satirical or extremely off - beat literature, there might be some allusions that could be misconstrued as such. But it's not a common or mainstream literary theme. Most literature focuses on more positive, profound or at least more acceptable human experiences.
There are no well - known 'adult pant piss stories' in literature that come to mind. Literature aims to explore the human condition in a more meaningful way. Themes like these are more of a niche or shock - value kind of idea that doesn't have a significant place in the overall landscape of literature.
I can't really recall any specific 'adult pant piss stories' in well - known literature. Classic literature usually deals with themes like love, war, social justice etc. Contemporary literature also doesn't typically center around such a strange and somewhat inappropriate topic. It's not something that is widely explored or celebrated in the literary world.
