You wake up tied to a gynecology chair (you are men) but you notice that your male reproductive system was eliminated and instead now there is a female one you are extremely confused until you hear a voice which tells you that you were modified to produce milk and that in addition to the milk fluids produced through the stimulation will also be stored and that before each stimulating session there will be a humiliation section where you will be dressed, marked and will make you pose all to humiliate you
