What it is

This 6-inch realistic dildo by Doc Johnson pairs anatomical precision with the brand's innovative Vac-U-Lock attachment system. The flesh-toned design mimics natural human anatomy, while the medical-grade silicone construction ensures body safety and durability. Its proportional girth and detailed texturing create genuine sensory feedback during use. The Vac-U-Lock mechanism eliminates slippage, holding firm throughout intense scenes without wobble or drift.

What sets it apart is the engineering: the vacuum-seal attachment guarantees stability that cheaper suction-cup systems can't match. It arrives with the Ultra Harness 2, attachment powder for smooth connection, and full instructions. See the full BDSM Australia range of Strap-On-Me for other harness and dildo combinations.

How to use a strap on sextoy

Apply the included attachment powder to the Vac-U-Lock connector on both the dildo and harness. This ensures smooth, secure connection. Wrap the Ultra Harness 2 around your waist and adjust all straps for a snug, comfortable fit. Insert the dildo into the Vac-U-Lock base until you hear or feel the vacuum seal engage. Always test positioning and stability before beginning intimate play.

During use, the Vac-U-Lock system keeps the dildo locked in place through penetration, thrusting, and position changes. Water-based lubricant on the dildo itself reduces friction and increases comfort. Pair this with Sensuva On for enhanced sensation and glide. After play, remove the dildo, clean both it and the harness thoroughly with warm water and mild soap, then air dry completely.

Always use water-based lubricant, start slowly, and communicate clearly with your partner; clean thoroughly after each use and never share without proper cleaning between users. 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

Wash the dildo and harness with warm water and mild antibacterial soap after every use. Dry completely with a soft cloth or allow to air dry. Store both pieces in a cool, dry place away from direct sunlight and heat sources. Keep the attachment powder in a sealed container. Never use silicone-based lubricants, as they degrade the material over time.

Mistress Athena's training notes

This cock has been my tool of choice for years. The Vac-U-Lock system gives me absolute control—no slipping, no loss of momentum, no breaking the scene. My submissives feel the stability and know I'm in command. The realistic texture creates psychological vulnerability; many struggle with the anatomical authenticity in ways they don't with abstract toys.

Six inches proves the perfect length for my purposes. Substantial enough to challenge, not so large it terrorizes on first contact. I vary depth and speed deliberately, watching their breathing shift as they surrender control. The medical-grade silicone holds up to frequent, intense use without degrading.

Positioning matters. The harness design lets me maintain eye contact while I work, reading every micro-expression of resistance or submission. Combined with sensory deprivation or verbal protocol, this tool becomes a gateway to profound psychological scenes. Attachment powder ensures the connection stays flawless throughout.
