Bonus Image Provenance: I commissioned Bacchus at ErosBlog to research this image further, and he has come up with the following additional details.
A caption in a re-tumble put me onto the name of artist Joe Chiodo (“Chiodo” can also be seen on the robot’s arm):

That led me to this gallery of Joe Chiodo art including your image in higher resolution:

Chiodo has a wikipedia entry:

He also has a web page:

The galleries there do not seem to include your image, but there is a page showing the various books of artwork Chiodo has published:

There is another nice gallery here with more of his work:

There’s a very large gallery of his work here (215 images spread across four pages, navigation in Russian):
Notable for thematic similarity to your image is this robot lobster plucking at a woman’s bikini:

Plus a bonus tube-boy:
Another 7-page gallery of his work is here:

Finally, it’s noteworthy that Joe Choido has done a “Slave Leia” image, which is in the immense private library of Star Wars art owned by John Higashi:

Bacchus is actively taking image research commissions, and if you have adult imagery you’re curious to learn more about, I encourage you to visit Bacchus’s introductory post for his image-searching service, where you can find details about how to commission him.
