Original post here. This image was researched by Bacchus at ErosBlog as part of the “Γ commission.” It was originally published at Hedonix as “Γ 005 – It Doesn’t Reach!” (There was no Γ 004 due to a numbering error on my part.) Here is Bacchus’s research:

This artwork is by Pixiv artist 鏑樹由貴 (Kabura-ju Yuki) and appears here under the title 届かないわ (machine translation: “not reach”). There is a caption that machine translates to “Maggie from Virtual Girl” and also a tag that machine-translates as “Amy Thompson”. These references are presumably to the novel Virtual Girl by Amy Thompson, in which a man illegally creates a robotic companion (Maggie?) with artificial intelligence.

The same artist appears on DeviantArt under the name yuki-kaburagi with a small gallery of artwork.
