Mens nipple suction cups

 Available in three sizes - the larger the cup, the stronger the suck. With regular use they are believed to develop the nipples over time.
Simply squeeze one of the rubber cups and place directly over the nipple to create suction which causes the nipple to become enlarged.
For best results, nipple area should be clean-shaven and suction cups should be lubed.
