What it is

This starter set from Doc Johnson combines three distinct dildos with wireless vibration and a harness system designed for both solo and partnered exploration. Each attachment features ULTRASKYN dual-density silicone—a firm inner core wrapped in a soft, realistic outer layer. The patented Vac-U-Lock mechanism lets you swap attachments in seconds and rotate them 360 degrees for unrestricted movement. This design gives you genuine flexibility without fumbling or downtime.

What sets it apart is the complete package approach. Rather than buying pieces separately, you get three different sizes and textures, a wireless remote with seven vibration patterns, an adjustable harness, and care products all together. See the full BDSM Australia range of Strap-On-Me for more options in this category.

Key features

  • Three interchangeable attachments: 5.5-inch textured, 6-inch spiral, and 7-inch thin options let you customize sensation and depth for different moods or partners.
  • Dual-density ULTRASKYN silicone: Body-safe material with a soft outer feel and firm core provides realistic texture and comfortable penetration.
  • Wireless remote vibration: Seven distinct patterns and intensity settings give you full control over stimulation without cords or complications.
  • 360-degree Vac-U-Lock system: Attachments lock securely and rotate freely, allowing natural movement and easy mid-scene swaps.
  • Adjustable harness included: Fits most body types and works hands-free for partnered or solo strap-on play.

Specifications

  • Attachment dimensions: 7-inch thin (7.5" length × 1.5" diameter), 6-inch spiral (6" length × 1.5" diameter), 5.5-inch textured (5.5" length × 1.5" diameter).
  • Material: Phthalate-free ULTRASKYN silicone with dual-density construction (soft outer layer, firm inner core).
  • Power: Rechargeable lithium-ion battery, wireless remote control, seven vibration modes.
  • Waterproof: Yes, fully submersible for shower or bath play.
  • Box contents: Three dildos, wireless vibrating plug, adjustable harness, water-based lubricant, toy cleaner, restoration powder.

How to use a strap on sextoy

Start by selecting your preferred attachment and securing it into the Vac-U-Lock base using firm pressure until it clicks. Attach the base to your harness and adjust the straps for a snug, comfortable fit around your hips and thighs. Apply generous water-based lubricant to both the attachment and your partner's entrance. Insert slowly, allowing them to adjust to the size and sensation before building rhythm or speed.

Once you're comfortable, use the wireless remote to activate vibration and explore different patterns and intensities. You can swap attachments mid-scene by simply releasing the lock—the system's versatility means you can shift sensations without stopping. Many users find that pairing this with partner communication and checking in frequently makes for safer, more satisfying scenes. Explore the Sensuva On collection for complementary products that enhance strap-on play.

Always use generous water-based lubricant, go slowly on initial insertion, communicate with your partner throughout, and clean thoroughly with the included toy cleaner after each use. 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 all three attachments and the harness with warm water and the included toy cleaner after every use. Dry completely before storage to prevent moisture buildup. Store in the provided bag in a cool, dry place away from direct sunlight. Use the included restoration powder on the silicone attachments regularly to maintain their soft feel and prevent degradation. Never use silicone-based lubricants, as they can damage the material.

Mistress Athena's training notes

Three attachments mean three distinct psychological experiences. The textured option creates intensity that breaks through resistance; the spiral demands focus and breath control; the smooth one offers relief and false security. Switching between them keeps a submissive perpetually uncertain, which is precisely where control lives.

Wireless vibration adds layers of unpredictability I control completely. A submissive never knows when sensation will spike or ease. My hand on the remote is my hand on their nervous system. Watching them try to anticipate the next pattern—that's where real submission deepens.

The Vac-U-Lock system's speed matters more than people realize. Swapping attachments without ceremony, without asking permission, reinforces that their body is mine to reconfigure as I choose. The psychological edge of that efficiency rivals the physical sensation.
