KDKJ-034 - Android and the Dr.

It's an AV where Akari Shiramura is an android and the male actor is her creator. There's nothing particularly sci-fi about it; they just calmly have normal sex indoors. However, thanks to the 'setting,' you don't have to explain why a young woman would feel affection for an old, bald, overweight guy, so it's enjoyable to watch. You could call it a 'master' dynamic or whatever.
