Looking for an old hentai with a redhead and a robot.

I recently came across attached WEBM featuring a redhead girl being assaulted by a robot.
I'd really love to know where it's from.

Would be very grateful if anyone could point me in the right direction.

o-parts?

yes that the opening scene from O-parts where the girl is alone in her room

Thank you, managed to find a download for it (in horrible quality I might add).

Was promptly disappointed by how short and uneventful it was. But thank you nevertheless.
