Vac-U-Lock Silicone Pegging Set By Doc Johnson

Pegging can feel intimidating if you're unsure about size or technique. This set removes that guesswork with three graduated silicone attachments, a secure harness, and everything you need to explore comfortably at your own pace.

What it is

The Vac-U-Lock Silicone Pegging Set is a complete pegging kit designed for couples exploring power exchange together. It includes three interchangeable silicone attachments—5, 6, and 7 inches in total length—that connect securely to a padded harness. Each attachment is crafted from medical-grade Platinum Premium Silicone, a non-porous material that's hypoallergenic and body-safe. The graduated sizes let you start small and progress at your own comfort level, making it suitable for both beginners and experienced users.

What sets this kit apart is its Vac-U-Lock system, which creates a secure vacuum seal between harness and attachment, eliminating wobble and ensuring reliable connection during use. The Supreme Harness features adjustable straps and cushioning to distribute pressure evenly across your body.

How to use a strap on sextoy

Select the attachment that matches your comfort level—most couples start with the 5-inch size. Insert it firmly into the Vac-U-Lock harness until you hear or feel a secure seal. Adjust the harness straps so it fits snugly without pinching, then apply generous water-based lubricant to both the attachment and the receiving partner's body. Begin slowly, allowing time for relaxation and adjustment before increasing depth or pace. Maintain open communication throughout, checking in regularly about comfort and sensation.

As confidence grows, you can experiment with different attachments to vary sensation and intensity. Some couples use the suction cup base for solo exploration or hands-free positioning during partnered play. Combining this set with restraints or power-exchange elements deepens the psychological dimension of the experience.

Care and storage

Wash each attachment immediately after use with the included toy cleaner and warm water, then air-dry completely before storing. Store the harness and attachments in a cool, dry place away from direct sunlight or heat. Apply the refresh powder to the silicone periodically to maintain its texture and appearance. Never share attachments without cleaning thoroughly between users, and inspect silicone regularly for any signs of wear or damage.

Mistress Athena's training notes

Control flows from preparation, and this set's graduated sizing lets me calibrate my submissive's experience precisely. Starting with the 5-inch attachment establishes baseline vulnerability; I observe their breathing, muscle tension, and psychological state before advancing. The Vac-U-Lock system's secure connection means I can focus entirely on technique and my submissive's response rather than equipment failure. Each size transition becomes a psychological moment—a test of their willingness to surrender deeper.

My technique emphasizes deliberate pacing and sustained eye contact. The silicone's smooth texture contrasts beautifully with the harness's structure, creating layered sensations my submissive cannot anticipate. I've found that alternating between sizes during a single scene—moving from 5 to 6 inches, then back to 5—creates powerful psychological tension around control and unpredictability. Their body adapts, then suddenly confronts a new threshold.

What makes this set invaluable in my practice is its reliability. The Vac-U-Lock connection never fails mid-scene, which means I maintain absolute dominance without technical interruption. Aftercare follows naturally once we've finished—the silicone's medical-grade safety means I can focus entirely on their emotional and physical recovery rather than worrying about material integrity.
