I would love to find someone with a machine like that. Tied down all defenseless at a Master's mercy. Put those cups on big titties and have enough suction until they completely fill the cups. It would be amazing to see milk come out considering I've never been pregnant. I would love it if the Master would pound my tight pussy relentlessly with his big cock at the same time holding a vibe on my poor little clit as he pounds me hard and those cups go to town on my tits
