A long time ago, I played a machine-translated game and liked it a lot. In the game, we control 3-4 chars: The MC, his childhood friend who is a sexy girl with long blond hair (who is also a princess I think), a loli with purple twin tail, and I dont remember if there was a 3rd girl. Maybe a red-haired girl, but I'm not sure at all.
The MC's party had to lead an expedition of some kind with a bunch of soldiers, and they first met the purple loli as a powerful enemy mage general. All the enemies used some kind of drug translated as poron and would immediately impregnate the female chars as soon as they manage to come inside them. Yes, immediately after the battle.
I think there was also day-night cycle, where MC party go exploring during the day and female char did "side jobs" during the night, but I'm not sure about this one detail.
That's about all I can remember. If anyone could help me find this game's name or link, thank you very much
