Add a new level of meanness and pain to your nipple play with these Tyrant spiked clover clamps! The meanest of our collection, these Japanese Clover clamps only intensify in pressure as you pull them or put weights on them! Instead of a soft, flat, or padded clamp, these have round-tipped, spiked, metal clamps that really bite down on the nipples and areola! Enjoy adding some spice to your pain-and-pleasure play! The metal can be heated or cooled to add as part of a temperature-play scene. To clean, us warm water and mild soap, then rinse with water and pat dry. All metal is nickel-free for sensitive skin. After you've warmed up your submissive partner, you grab the clamps. You rub the nipples to get them to wake up and become perky. Then you pinch the nipple, pulling it away from the chest, and clamp the ends of the clover clamp right behind the nipple, on the areola. You slowly, very slowly release so the pressure builds and doesn't shock them. Then you slowly release the clamp so they can feel the added weight of the metal clamp and feel the spiked tips digging in. You remind them to breathe, let them calm down and center, and then do the same on the other side. You play with them as usual, adding in light slaps and tugging their hair, using a Wartenberg wheel over their flesh and flogging them. Then after about 30 minutes or less, you release the clamps and enjoy the look on their face and their cry of pain as the blood rushes back, awakening the senses in their nipples once more! Measurements: Clamps: 3.5 inches long x 1.5 inches wide. Chain: 14.75 inches long. Clamps open up to 0.24 inches wide.
