Alright, so, there's this cute girl, and I store my cum in the containers, right?
Well, what happened, is, firstly, when I wasn't looking, she secretly siphoned the cum out of my cum containers.
When I found out about this, at first I was obviously upset with her because I presumed this was for one of her own nefarious purposes, but it turns out she did this so she could inject it into her bladder to then be able to pee it out.
I asked why she would want do this and apparently she just wanted to see what it feels like.
