The major differences between cow milkers and goat milkers are that a goat milker has one or two pairs of two slightly smaller teatcups connected to a milker bucket.
A cow milker has four slightly larger teatcups connected to a milking claw that is connected to a milker bucket.
Milking feels just great using a good milking machine with lots of lube and a really nice and comfortable suction !

Intriguing!

There are lots of videos with milking machines used for really pleasant vacuum massage for handsfree masturbation !
I have even posted some videos and pictures myself using one of my cow milking machines with a fifth extra teatcup added for a pleasant milking of my penis while the four ordinary teatcups gives me a really pleasant milking on my nipples and balls at the same time as my penis is milked comfortably by the fifth extra teatcup in a really pleasant way !

Milking machine masturbation is fantastic! I've had some mind-blowing orgasms with my machine. It's incredibly erotic to watch the teat cup slide up and down my cock and know that the machine will force me to have a very intense orgasm.

Boy, this makes me wonder how much cum is in our 1% milk we drink? ha ha

I'd love to get my prick into a milking machine!

The videos and pictures with modified milking machine are showing me using my modified milking machine with a fifth extra teacup added to an ordinary cow milking machine to make the modified milking machine into a five way milking machine that milks my nipples and penis and testicles simultaneously and gives me a very thorough milking experience in a really pleasant way with absolutely no way to resist the very comfortable yet absolutely relentless pleasant milking experience with all the most sexually sensitive parts of my body being comfortably milked simultaneously.
