OK I see, that's what I thought, it's futa on female essentially. That's pretty much the consensus, if you look it up on rule34
or any big website that's what you'll find under "futa on female", a girl with a cock fucks a normal girl.
I understand that there's people out there, including on this site, who like to get into big scholastic debates about futa, whether they should also have a pussy or not, etc and I get that those people are annoying to deal with but unfortunately there's a certain percentage of people that will be a bit overzealous in any large online community. It's a small but very loud minority.
I still think that it's not a good idea to have "this game has no futa" in big font in the OP, because that will just be confusing for the majority of people checking out the game.
