If you adore the sensation of nipple stimulation but find clamps a little too intense, you're in luck! Colt from CalExotics presents a completely customizable pair of vacuum suckers that'll pull and tug at your/their nipples with absolutely no pinch involved.  

Nice and sturdy, the large, all-encompassing Nipple Pro-Suckers will fully surround your or your partner's nipples (or clitoris, or other outer sweet spots) thanks to a big, circular opening. Press a Sucker against an erogenous zone in need/want of some suction, and simply twist the top car of your Sucker to activate suction. You'll be able to see the internal plunger mechanism rise as it draws your/their skin upward. Twist the cap in the opposite direction to release the internal pressure.

In firm, extra hygienic ABS plastic, the Pro-Suckers are easy to clean with some soapy water or a good toy care fluid/foam.

*Each Pro-Sucker is approximately 4'/10.2cm long and  about 1.1'/2.8cm in diameter.
