Aside from Monica being a Futa, i also think that there is a possibility that she is the "father" too(i meant she fucked the mother and bam! MC born!!), the reason ? I just think Monica and Mother have some deep relation...
And i think
is the blackmailer, i thought this when you choose the option "try to smell" and i dont remember the quote but smelled like some equine/bovine animal "a mare in estrus?" she said. I think she is some kind of bovine/equine character, maybe some kind of female satyr, also maybe futa.
Am i think too much ? Maybe.
