Treat yourself or your partner to some intense stimulation with this red nipple sucker set. It is specially designed to make your nipples look and feel extra hard and enlarged. A sex toy that sucks and tickles both your nipples at the same time? Slip one of the supplied rubber rings (4 sets of different sizes) over the nozzle of the pump (2 different sized nozzles for small/large nipples) , squeeze the bulb, put the nozzle over the nipple and then release the bulb slowly to apply suction. It may take a couple of goes to draw a good length of nipple inwards. When you've achieved the right length, slip the ring down over the nipple. It creates a wonderfully round button effect that feels fantastic and looks superb under a sweater or silk blouse.
