Right, so the mouse controls the rhythm. That's the whole thing. You're not just watching, you're sort of... conducting the motion. Slide it up, Miku slides down. Jerk it in a little circle and she does this little grind that honestly caught me off guard the first time. Spent way too long just making her do tiny, stuttering movements, like a broken animatronic at a theme park ride that got a lot more adult. The song loops. It's a Vocaloid track, obviously, and it's catchy in that way that makes you forget you've heard the same fifteen second chorus for the last ten minutes. There's an auto mode, which is fine, I guess, but it feels like giving up. Like admitting you can't manually pilot a virtual idol onto a disembodied cock.

The POV angle is strictly from the dick's perspective, which is a choice. You see her face, her chest, the whole... situation. The creampie finish is the stated goal, the big reward. The animation for it is weirdly detailed, a single moment of fluid physics that the rest of the game doesn't really earn. The rest of the time her hair moves like it's underwater, even when she's going slow. I wish there was a button to just mute the wet sounds and keep the song. The squelching is mixed way too high, like someone stomping through mud in heavy boots. It's a small thing, but it's the thing I keep thinking about.

The whole setup is so aggressively specific. It's not a game, it's a single interactive loop with a famous blue-haired hologram. You're not unlocking anything, there's no dialogue tree. Just you, your mouse, and Miku's blank, unchanging expression while she rides. The japanese text on the UI buttons is a nice touch, makes it feel like some obscure browser artifact from 2008. Forgot to mention, the sound really is the best part. Not the sex sounds, god no, but the actual song. It's the only thing that makes the repetitive motion feel like a weirdly hypnotic music video you're ruining.
