I think there have been a few things like that. I also remember this one comic/manga where zombies with either masks or teeth removed were being used in the workplace and these two dudes decide to rape a female zombie, figuring that the disease can't spread like a STD.... but it does and they end up in that same zombie-slave workforce.
Unrelated, but it brings to mind a line from Stroker and Hoop where a company man mentions having, "a living wage for our living workers," and Hoop muses, "Hm, what other kind of workers are there?"... only to learn they're using zombies for slave labor. That show was canceled long before its time >_> #NinjasDontHaveDayJobs
Can you really rape a zombie? What's the name of that one? Also yeah that show was amazing. ---
