What do you mean by "looks like Peasant's Quest"? Because if it's just 3d games with monster girls, there are plenty. Now if you want a game that looks like Peasant's Quest and has the same fetishes, that's where you start running into problems. If you add gameplay onto that, it gets even harder (not that you'd want to lmao RPGM sucks dick).
Sorcerer by Talrothal is a 3DCG VN with monster girls. You can get everyone pregnant, but they only show in the very last stretch of the game. Talrothal's other games, such as Terminus Reach: Sentinel, are similar.
Renryuu Ascension is RPGM and involves you repeatedly impregnating everyone, but it's not 3DCG. Same goes for Monster Girl 1,000.
The Rise of Vruk and Legend of the Goblins are RPGM with 3DCG and a focus on pregnancy fetish, but you play as little green shits instead of a human, so you might not like that.
All in all, if what you're looking for is "Peasant's Quest 2", you're gonna have to make it yourself.
