When Thin Finn thins out, things get really tough for you. With its sleek and lightweight body, the urethral dilator brings the full range of sensations of electrostimulation to excitingly unusual places. Its gently rounded tips and the seamlessly smooth transition between the poles not only give it an elegant look, but also make it easy to insert into the urethra with a little practice (and lubricant). And as soon as Thin Finn is in place, it combines the bittersweet stretching from the inside with the endless teasing of the impulses to create a unique symphony.Right into the heart of happiness: After just a few centimeters, the insulation between the two poles of this compact MystimE-Stim dilator is achieved. To activate the two poles, you need a stimulation current device such as the Cluster Buster, the Mystim Tension Lover or the Mystim Pure Vibes. The electrical stimulation begins immediately. The stimulation current tickles, tingles or pulsates even when stretching. The trip into the tube is even more intense if you warm Thin Finn on the heater or cool it down in the refrigerator before use.If you want, the tingling, pleasurable pleasure will kick in for hours. You can vary and intensify the stimulation so that you are quickly driven to sensational climaxes. Or so that you can only save yourself a few seconds from coming. It all depends on your preferences - and your stimulation current setting. One Year Warranty.
