What it is

The Vac-U-Lock 2 Leather Strap-On with Plug is a harness system built for users who want real flexibility during intimate play. Its full-grain leather construction molds to your body, while adjustable straps ensure a secure fit across a wide range of sizes. The open crotch design lets you stay stimulated while wearing it, and the medical-grade ABS plastic plug connects to any Vac-U-Lock compatible toy—meaning you can switch attachments in seconds without removing the harness.

What sets this harness apart is its rapid-change system. Most strap-ons lock you into one toy for the entire scene; this one lets you adapt instantly. The leather feels substantial and looks professional, building psychological intensity before physical contact even begins.

How to use a strap on sextoy

Start by adjusting the leather straps to fit snugly around your waist and thighs. The harness should feel secure but not restrictive. Insert the Vac-U-Lock plug firmly into the central attachment point, then choose your first toy—dildo, vibrator, or textured attachment. Align the toy's Vac-U-Lock connector with the plug and snap it down until you hear or feel it lock. Test the connection before beginning play to ensure it's tight.

During your scene, you can change toys by pressing the release button on the plug and swapping in a new attachment. This flexibility lets you explore different sensations without pausing your scene. The open crotch design means you can enjoy direct stimulation at the same time. For advanced power exchange dynamics, explore the Sensuva On range of complementary products to deepen your experience.

Always clean the harness and any attachments before and after use with warm soapy water or toy cleaner, and apply a water-based lubricant to any insertable toys to reduce friction and discomfort. Safety first. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Discontinue use immediately if you experience pain, numbness, discolouration, irritation or discomfort, and seek advice from a qualified medical professional if you have a relevant health condition or if symptoms persist.

Care and storage

Wipe the leather harness with a damp cloth and mild soap after each use, then air-dry completely. Sanitize the ABS plastic plug with adult toy cleaner or warm soapy water. Store the entire system in a cool, dry place away from direct sunlight. Condition the leather every few months with a leather care product to keep it supple and prevent cracking.

Mistress Athena's training notes

This harness has become essential in my practice. The leather feels commanding against skin, and the open design lets me watch every reaction without obstruction. I can read my submissive's body language while maintaining complete control. Switching toys mid-scene keeps them psychologically off-balance—they never know what's coming next.

Strategic attachment changes are my favorite tool for training. I'll start with something manageable, then escalate intensity within seconds. The Vac-U-Lock mechanism means zero fumbling—just clean, decisive switches that reinforce my dominance. My submissives learn quickly that resistance becomes impossible when I control the pace and sensation.

The leather construction adds psychological weight to every moment. It's not just functional; it's a symbol of power and protocol. When they see me reaching for this harness, they already understand what's about to happen. That anticipation—that surrender to the inevitable—is where real control lives.
