Boy I said this in a previous reply but I have to repeat myself.
Dude there has been porn of Zeraora LONG before any official work, it came the same day the unintentional leak came out last year and then least 10 porn images just on e621 last year. You're a literal Slowpoke, oh dear they're multiplying!

But even then the first image to use the zeraora tag on this site was from 5 months ago, unless you’re referring to this being the first nsfw image of its type which is also incorrect because there were several similar pieces by this artist that has been posted here for the past few weeks, but keep getting taken down for not following the nsfw image guidelines.
