The whole thing feels like someone ripped a chunk out of a bigger project and slapped it online, which is exactly what happened. Succubus Twins part1 is a WIP scene from The Legend of LUST, and it shows. You get two demon girls, both stacked, both in lingerie, both looking at you like they just found a new toy. The customization menu is where I spent most of my time, honestly. Hair color, skin tone, boob size slider that goes from "nice" to "back problems", different outfits, accessories. You can even make their pussies get wet on command, which is a weird thing to type but here we are.
The drag and drop menus are a nice touch, you can resize them too, which helps when you're trying to see what you're actually doing. But there's no sex animation yet. None. Just the girls standing there, maybe getting wet, maybe changing clothes. It's like being handed a very detailed action figure and told the batteries are coming next month. The twins themselves are hot, don't get me wrong. Big tits, demon horns, that whole "we exist to please you" energy. But after five minutes of sliding boob sizes around, you start wondering if you're playing a game or just fiddling with a character creator that forgot to include the game part.
The devs say they're working on an expansion with actual sex animations, new styles, more options. That's great, but right now this is basically a tech demo with a pulse. If you're into the customization aspect, you'll lose an afternoon. If you came here to actually fuck a succubus, you're gonna be disappointed. The wet pussy toggle is fun for about ten seconds. Then you realize that's the most action you're getting.
I keep thinking about that one menu option where you can adjust their expressions. They look eager, hungry, ready. And then nothing happens. It's like edging but the game is the one doing it to you.
