Original post here. This image was researched by Bacchus at ErosBlog as part of the “Γ commission.” The research was originally published at Hedonix as “Γ 061 – Alita’s Pleasure.” Here is what Bacchus found.

This artwork is by the artist Hazyl, who has titled it (perhaps working with less-than-perfect English) Tuned Alita secret time. The artist writes:

Here is a special situation for Alita, relatively chaste character putting in a situation of sexual experiment. A first experience which seems to me possible with its body of ” tuned “. In your appreciation;)

Voici une mise en scène de gally, personnage relativement chaste auquel je me suis exercé à mettre dans une situation d’expérimentation sexuelle. Une première expérience qui me semble possible avec son corps de “tuned”. À votre appréciation 😉

From the comments on the artwork it becomes clear that the Alita depicted in the artwork is the titular cyborg Alita character from the Japanese manga series Battle Angel Alita. Her fan art depictions are numerous and varied; see, e.g., these 64 examples at Rule 34.
