ONNA-011 - Nagai Mihina Machine Vibe Collection

Note that this is a compilation. It's literally machine-vibe focused, but there are scenes with men as well. Personally, I don't care about anything other than the machine vibe, so I wish they had cut the scenes with men, but that's just my preference so I won't factor it into the rating. Also, tacking on a random segment from another work at the end feels a bit half-baked.
