Thanks for a detailed response!

> I'm normally not into guro featuring characters I'm actually into
Interesting, it's quite the opposite for me. Since I'm all about consensual and casual guro where characters enjoy whatever the hell is happening, I don't see anything to be upset about it involving the characters I like. So it's just combining one thing I like (characters) with another thing I like (guro), making it all the more enjoyable.

Oh well. If it helps, the way my Kagamine twins think about urine is as of a physical manifestation / materialization of fun, because of how it can come out if you laugh very hard. In this way it's similar to semen coming out when you feel very good (and then they think of semen as a manifestation of pleasure or bliss).
The prologue to Innocence that I've never written was supposed to mention how as little kids they would have tickle fights until one of them wets themselves, so they would associate urine with the fun of that game, and for the winning twin with the joy victory (it had a scene where as a result of another tickle fight Rin ended up peeing on Len's face, and he licks his lips smugly, enjoying the taste of victory).
