Ultimate Stretch and Shock Electro Rack – E-Stim Penis & Testicles Electrode by Sir Dastardly

The Ultimate Stretch and Shock Electro Rack isn’t for the faint of heart – it’s for those who crave intensity, the kind that sends shivers down your spine and leaves you breathless. This device is designed to push boundaries, blending the agony of stretching with the electrifying thrill of e-stim. If you’ve ever fantasized about that perfect mix of pain and pleasure, this might just be your new favorite toy.

What Makes It Special?

First impressions? This thing looks like it belongs in some old-school asylum, a relic of bizarre medical experiments. But don’t be fooled – this machine is engineered for pure, unfiltered pleasure (or exquisite torment, depending on your taste). The base ring locks everything in place, gripping both cock and balls while six brass studs line either side, ready to send pulses of electricity through your most sensitive areas. Whether you’re a newbie to electro-stimulation or a seasoned pro, the adjustability ensures you get the exact level of sensation you’re after – from a teasing tingle to a full-blown jolt.

The Main Event: The Cock Clamp

Now, let’s talk about the real star here – the cock clamp. It’s not just any clamp; this is a marvel of sadistic engineering. Fitted with brass studs that create both positive and negative charges, it lets you control exactly how the current moves through your flesh. It’s not just about the shock itself – it’s about the build-up, the tension, and that delicious anticipation before each pulse hits.

You can also adjust the clamp to stretch the penis to your preferred level of tension. Whether you want just a bit of pressure or an extreme pull, the tightening mechanism ensures everything stays put, no matter how aroused you get. That means uninterrupted, relentless stimulation, exactly the way you like it.

Urethral Stimulation: Taking Things Up a Notch

If you thought we were stopping at external stimulation, think again. This beast includes a urethral sound platform for deep and intrusive sensory pleasure and pain. If you’re into sounds, you can attach your own or use one of the optional kit items – hollow tapered, solid gauged, or our favourite, solid ribbed; plugging it directly into the 4mm banana socket. Once the current starts flowing through the urethra, the sensation is next-level – intense, unpredictable, and utterly consuming.

Zap-A-Dee-Doo-Dah Those Testicles

The Electro Rack doesn’t ignore the boys downstairs. The testicle stretch and shock function holds them securely while adjustable rods allow you to stretch them outward or downward, depending on your preference. The 20mm brass contact disks positioned underneath ensure the shocks land exactly where they need to, delivering anything from a slow, creeping burn to a sharp, unforgiving jolt.

Customization & Setup

One of the best things about this device is its versatility. The entire rack can be broken down for storage, and each section – cock, balls, urethra – can be used separately or together. Three leads come included, allowing you to connect the setup to your powerbox. If your powerbox has a 3.5mm mini-jack output (which most do), you’ll need an adapter to split the positive and negative poles – ensuring you get the perfect balance of stimulation.

Worried about assembly? Don’t be. It arrives with a clear, image-based manual, making setup easy. Once everything is in place, the rack stays secure, even without suspension. It may not be overly heavy, but when it’s in action, it’s intimidating in all the right ways.
