A Spanish translation is something that’s high on my interest list. With everything, though, it’ll take a lot of work. Currently, that work is going into the art and the dialogue that still needs to be finished. So I can’t promise anything.
There's a YouTube channel that translates games into hentai; they have many in their catalog, but they haven't translated this one yet. Maybe you can contact the translator, or I can try to convince them to translate this game, with their permission, of course. The channel is called Tio Eroge, and the other channel is Arokai Traducciones.
