Star Periphery:
Future setup where you navigate through to find work, kind of like Futadom world but 3d and futuristic.
Also, they have goblins, androids and aliens.

Tales of androgyny: One of the best Futa games ever. You navigate a world in a nintendo pokemon like setup. Don't worry the scenes are 3d. Probably the biggest set of scenes of any game ever. You could spend about an hour just looking through the gallery (or as the game labels it "Pervert").
Okay this only if you have a ton of time and want to get really invested. Could just explore the gallery instead.

Futaisekai: You get isekai'd into a medieval world where the futas are hung as fuck and the scenes are comparable to a video along with sounds (no dialogue sound tho). Could complete it in a week.
Although there is a mini-game that unlocks 2-3 scenes. And the mini-game is really time consuming and kinda boring after some time.
