Futanari and newhalf aren't the same thing. It's either one or the other, not both. And a girl can't be otoko no ko, even if she has a penis.
Also, please don't make up new tags unless you have a compelling reason to do so. If by r34 you mean Rule 34, we have a pool for that, and this post likely doesn't fit it anyway. Nsfw is particularly pointless given that this site has a built-in rating system. And the wiki definition for hentai specifically instructs you to not use it as a tag.
