Ok, I know this is just for kinky fun, but that machine would never help induce lactation. To be a real milking machine it needs a valve called a pulsator that will allow the rubber lining of the suction cups to open and release continously to replicate powerful suckling to encourage milk let down. You need to come to a real farmer like me who has a real cow milking machine. Of course the most effective way to induce lactation is by regular suckling multiple times per day, every day for months along with taking foods and supplements to aid milk production. But this was still cute 😍.
