Help Identifying This Hentai Image Description please

[Murakumo]

I need help identifying the origin of a hentai image: it is a girl lying down on her back, biting her right hand's index finger while touching her panties and masturbating. she is not wearing any bottom except her panties, and only has top, I think with sailor uniform top and her brassiere is showing.

Does anyone know this image? I found it before in the early 2000s, before 2011


If you can provide a link or image, it would be much appreciated
