The scene you mention after you get back from the beach with Didac, in the premium version is complete in writing, but not yet in drawing. It's not really a minigame but it has several options which could be considered somehow a minigame, but nothing as complicated as the real "minigame" with Didac. In here though if you haven't got her pregnant before there's another chance to get her pregnant if you're submissive enough, in this case... (As protagonist, you cannot willingly get him/her pregnant, but there's a way to do it unwillingly).
