Woman being milked on an industrial milking machine, transparent suction cups strongly pulsing and pulling hard on her nipples, skin of her breasts clearly moving and deforming inward with every strong suck, visible breast jiggle and heavy movement, milk streams out of her nipples, large amount of milk comming from nipples filling the cups, cups fill up with milk, milk flowing through transparent hoses, subtle body movements, industrial machine operating, dark industrial lighting. Low deep humming and rhythmic low-pitched sucking sound from the machine with every pulse, not high-pitched. She moans and groans frequently with each suction in a scared erotic voice, saying “aaahh ssss it hurts my titties… aaah fsssss”, pain expression on her face. Clean isolated audio, no ambient noise, no echo, no music, no background sounds.
