"Milk plant" is really a whole set of hentai games in which big-titted dark-haired Tifa Lockhart (yep, the one from"Final fanatsy 7") is trying to resolve 1 problem - her funbags are overfilled with to relase them has to be sexually excited. That's where the player comes in - he always has a couple of playthings to bring Tifa the pleasure she seeks and helps her. Even tho the game is still made only in japanese version the gameplay here is pretty intuitive so it is possible to get thru teh game sans knowing the language. Just find active zones and trigger them to find various results. Sometimes these actions will probably be for fun and won't moev the story forward - in this case try to discover other points (keep noticed that sometimes it could be a text window).
