Inter-species is not my thing, so I will kinda avoid it.You don't fancy gettingcuckedshared by the orc? Watching your little sister get railed is "sharing" now so it's ok.
However, if it were, a female protagonist (Alice) would be lost in Wonderland, inhabited by pervy elves and bullying orcs, and would have to find her way back home. That would be the story.
From the beginning, I said that I had only implemented optional sharing.Yeah, is not ntr (at least for now) is optional sharing, also there is a giant letter "SHARING" in the option, unless the developer change that to ntr in the future, the tag is complete wrong.
I have found here that the definition of ntr varies from individual to individual, and some consider sharing as ntr as well, so I have to ask a moderator to tag ntr in the genre.
