Positive the creator made a more joke version of this called vibrator something
Yup! You're correct. It's called Violent Runner Vibrator

Since they're both so similar, I was doing some digging to try and find out if it was released before Sex★Machine or not.
The only release dates I could find for it are for the ebook release from May 2017, but it must've been released before then!
MangaDex says year 2000, but I'm not sure where they got that information, and it's the same year that Sex★Machine was released, so I'm not sure if it's true.
In the official description for the e-book release it says the series is a「未単行本化作品」or a "mitan kohon sakuhin", which, when translated, means a "work never before published in book form". So, I'd imagine it was serialized in a magazine at some point, and remained uncollected until the ebook version in 2017. Still unsure if it came before or after Sxmcn, though.
