that's great, do what you want to do, like you said this is your story, and if you're writting something you don't really wanna to, because someone else tell you to, the quality won't be the same at all
+ some suggestion like urination are somewhat a bit extrem, that's the kind of thing that divide people i think, a bit like the NTR, i guess, glad to know that it won't go there x) but well, anyone have their own preference
anyway, can't wait to see the contnuation of your story, hope you and the team are going well ! :)
