Mystim Slim Finn Urethral Sound

Tingling For Trouble?

Meet the Mystim Slim Finn Urethral Sound, the smaller, sleeker sibling to the infamous Tickleberry. Don’t let his size fool you—this little brother bites. At just 6mm wide, the Mystim Slim Finn Urethral Sound slides in smooth, teases deeper, and hits every nerve ending with surgical precision. He’s lean, polished, and oh-so-eager to please—perfect for subs who want to dip their toes (or their tips) into electro-sounding without the intimidation factor.

Crafted from medical-grade aluminum and polished to a flawless shine, Slim Finn conducts every pulse of current directly to your most sensitive spots. Connect him to any Mystim Power Box, and you’ll understand why smaller doesn’t mean softer. The tight, controlled channel intensifies each spark until you’re trembling, breathless, and begging for more.

This isn’t just about size—it’s about finesse. Slim’s rounded head glides in effortlessly with the right lube, and his slimmer build means more precision, more flexibility, and more playtime comfort. Whether you’re introducing your sub to urethral e-stim or refining your own technique, Slim’s your steady hand in the art of controlled shock and awe.

Sounding Safety 101:
Keep your session smart and sterile. Clean hands. Sterilized toy. Water-based lube (never saliva). Insert slowly, without force. Once you’re in comfortably, you can start the current and let the tension bloom. And when you’re done? Flush, clean, and reset for next time.

Because every great top knows: it’s not the size of the sound—it’s how you conduct it.

By the way: To activate the poles, you will need a stimulation current device such as the Mystim Cluster Buster, the Mystim Tension Lover or the Mystim Pure Vibes.
