A translation from COMIC Masyo 2016-12 by Nitta Jun.
Sadly it has nothing to do with actual robots.
A young guy is harshly rejected by his crush and seeks relief from a robot-themed prostitution service.
Nitta Jun's works almost always involve men or women being humiliated and shamed.

P.S. - Still working on a full color straight shotacon translation that I hope I can have out in the next week or so.
