Okay so the whole premise is a Naruto succubus helps you get off. Right. And it's Sakura, which is a choice. Not my first pick from the leaf village but I get the appeal, that pink hair and the attitude. The 3DCG model they used for her is... something. Her face is stuck in this one expression the whole time, like she's mildly annoyed you haven't finished yet, which honestly fits her character more than the dev probably intended. The animation loops are janky, her spine moves in ways that would kill a real shinobi, but the ass? Yeah, they spent their entire polygon budget on that ass. It's massive. Like, physics-defying, would need its own summoning jutsu massive.
The gameplay, if you can call it that, is basically a visual novel with one branching path that leads to different acts. You click, she talks in this weird text-to-speech monotone about draining your chakra, and then the scene shifts. There's a footjob scene that comes out of nowhere, no buildup, just suddenly her feet are there. And the anal scene, the camera clips through her thigh so you get this lovely view of the void inside her 3D model. Real immersive stuff. I spent way too long trying to angle the camera during the oral scene to avoid the dead-eyed stare, it's like she's looking through you at the Hokage monument or something. The succubus tail just phases through the bed too, which is a small thing but it bugged me. You'd think a demonic entity would have collision detection.
The toy integration is there, I guess. It syncs with some basic patterns, nothing fancy. The whole thing feels like someone discovered Blender last month and really, really wanted to see Sakura in a monster girl getup. And you know what? Fair. I've seen worse on certain forums. The comments section the dev mentions is probably a goldmine of unhinged requests. I'm not saying I didn't enjoy parts of it, the anal scene has a certain crude energy to it, but then the sound cuts out for three seconds and you're just watching a silent, glitchy succubus bounce. Wish there was a Hinata version, her personality would make the whole succubus thing way more interesting, but that'll never happen. The whole thing runs in browser so at least you don't have to commit to a download, just clear your history and pretend you were reading Boruto fan theories.
