You might as well make yourself or pay others for your game idea to be made. I love this game as it is and I find it a lot better without even just the option for futanari. Personally, I'd say better ideas would be like adding a mode after completing the coffee shop to show the result of the "training" mentioned in the game, adding multiple cow barista characters (I can not imagine their possible usage(like replace or work along-side the original(like maybe expanding the coffee shop playing area; adding the full interior or something))), pregnancy(whichIdislike), extreme teat modifications(bigger, thicker longer, insides showing, etc..) or chest x-ray. These ideas sound a lot more interesting and more related to the great theme of the game (which particularly include PURELY CHEST AND MILK, AND NO MALE PARTS(other than background customer characters)).
Man, I wished for "yuri" action and now there is this popular desire for adding fake female characters. ๐ Aren't (game-irrelevant)characters like Astolfo enough "traps" already?
