雙電極 Wartenberg 針輪

I was nervous the double wheels would feel too intense, but the current through both at once is actually smoother than I expected, more of a rolling tingle than a sharp zap. Paired with a TENS unit it turned a regular tie-and-tease night into something way more interesting.

The two wheels catch the skin just right—one rolling while the other digs in a fraction deeper, and the contrast keeps me on edge the whole session. It’s become my go-to for teasing before we bring out the restraints, and the handle feels solid enough to control the pressure exactly where I want it.

The double wheel glides like a completely different toy compared to single rollers, and the way each spike lands slightly offset from the other keeps my skin tingling long after we stop. Perfect for tying someone up and slowly dragging it down their inner thighs.
