Norway Pinwheels
A Pinwheel, or a so-called Wartenberg Wheel, was originally used as an instrument to test and explore the body's nerves. Today, Pinwheels are frequently used in BDSM to induce pleasure and pain.
The wheel is equipped with spikes that are passed over the skin for a really intense and nerve-tickling stimulation. Take it more gently for a tickling sensation or push harder to challenge your pain levels. Feel free to try combining with handcuffs and blindfolds - the feeling becomes even more intense and exciting!
