How Cow Milking Machines Work On BreastsOften I'm asked about the use of cow or goat milking machines on human breasts.
Dairy animals have different teat structures with cisterns. Thus they need different type of pumping equipment
than humans. Human "udders" don't have cistern type teats but sinuses behind the nipple.
If you check out this "ADULT" video you can see how cow milkers actually work, by having air bladders inside the
suction cups. Apart from the erotic suction alone which is really not enough, breasts can't be properly milked with these.
