When activated, the balls rotate inside the cups, their purpose to continually roll, tweak and massage the victim's defenseless nipples in every possible direction and with varying degrees of pressure from light strokes through to painful pinches.The level of vacuum each Stallion produces is constantly varied by its computer program.Sometimes the vacuum insists in creating a painful, pinching sensation.Sometimes merely a firm almost pleasant milking action.Each teat tormentor is independently computer controlled and its action random.One teat may be, for instance, be strongly sucked and lightly stroked whilst her 'sister' nipple may be tightly pinched but with little suction visa versa and versa visa.Not a pleasant thought or sensation for the girls who will experience this milking action for the full eight hour session.When all the girls had been mounted on their Stallions and connected to their milking machines, each is given an intravenous stimulant injection into her arm.This. So after my own orgasm into Z's cunt I sent her away to clean up dragging A into the giant master bedroom shower letting her clean my cock of mine and her younger sisters cum. I allowed A to clean and bath me in the shower before disappearing to the beach to be away from them for the day I only returned when Jim got home that evening to do amuch shorter version of the night before. I used his wife of course and allowed the new cuck to clean us but I limited my own orgasms to just two that night since thenext day was going to be my plan for using the sisters. My first decision was a simple one and that was what sister was going to be in charge and that was a simple one I decided it was obviously going to be the younger Z. I knew she harbored numerous grudges against her older sister one of them being that A was stealing her own fuck time from me. So with that decision done I set it up the next morning on wakening with Jim having just left I put A naked on her knees where I bound her.
