What it is

This strap-on system pairs a realistic 8-inch silicone dildo with an adjustable harness and the patented Vac-U-Lock attachment mechanism. The dildo features a rechargeable motor with multiple vibration settings, letting you dial intensity up or down during play. Body-safe silicone construction means it's non-porous, easy to clean, and safe for all users. The harness distributes weight evenly and adjusts to fit different body types comfortably.

What sets this apart is the Vac-U-Lock system—a vacuum-seal connection that locks accessories firmly in place without straps or clips. This means you can swap dildos mid-scene or integrate other compatible toys without stopping. See the full BDSM Australia range of Strap-On-Me products to explore the ecosystem.

Key features

  • Realistic design: Textured shaft mimics natural anatomy, with a flared base for stability inside the harness.
  • Multiple vibration modes: Cycle through intensities to match your rhythm or switch things up mid-scene.
  • Vac-U-Lock attachment: Vacuum-seal connection holds the dildo rock-solid with zero slipping or shifting.
  • Rechargeable motor: USB charging means no batteries to buy; full charge delivers hours of playtime.
  • Waterproof construction: Clean under running water, use in the shower, or splash without worry.

Specifications

  • Dildo dimensions: 8 inches total length, 1.5-inch circumference, approximately 0.5 pounds.
  • Material: 100% medical-grade silicone, hypoallergenic and phthalate-free.
  • Battery: Rechargeable lithium-ion via USB cable; runtime extends several hours per charge.
  • Waterproofing: Fully submersible; safe for water play and easy cleaning.
  • Included: Adjustable harness, vibrating dildo, Vac-U-Lock adapter, USB charging cable, drawstring storage bag.

How to use a strap on sextoy

Begin by inserting the Vac-U-Lock adapter into the harness pocket, then press the dildo's base firmly onto the adapter until you hear or feel the seal lock. Adjust the harness straps around your waist and between your legs for a snug, comfortable fit. Apply plenty of water-based lubricant to the shaft and your partner's entry point. Power on the dildo using the control button and select your desired vibration intensity.

During play, move at a pace that works for both of you—fast, slow, or varying rhythms. The vibration adds sensation without requiring constant thrusting. You can angle your hips to change the depth and angle of penetration. Explore different positions: missionary, doggy-style, or standing, depending on comfort and what you both enjoy. Explore the full Strap On Dildos range to find other compatible shaft options.

Keep all stimulation below the waist, never route current across the chest or through the heart, and avoid use entirely if you have a heart condition, use a pacemaker, or are pregnant. 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

After each use, wash the dildo and harness with warm soapy water or a dedicated toy cleaner, then rinse thoroughly. Pat dry with a clean cloth and air-dry completely before storage. Wipe down the Vac-U-Lock adapter with a damp cloth. Store the entire system in the provided bag, away from direct sunlight and extreme heat. Keep the charging cable in a safe place and charge the battery monthly if not in regular use.

Mistress Athena's training notes

This device commands respect in my dungeon. The Vac-U-Lock Vibrating 8 Realistic Cock With Harness gives me absolute control over every sensation my submissive experiences. Locking the shaft in place means zero distraction—only focus on what I decide to inflict. Power, precision, and presence: that's the trinity I build with this tool.

Vibration intensity becomes my language during a scene. I start low, watching for tells—breath catching, muscles tensing, eyes widening. Then I shift the setting higher, pushing past their comfort threshold into genuine surrender. The harness stays rock-solid throughout, allowing me fluid movement and unbroken command. This isn't about their pleasure alone; it's about demonstrating my will through their body's response.

What impresses me most is the silence of the motor. Submissives hear only my voice, my breathing, my footsteps—no mechanical whine to break the psychological intensity. That absence of noise deepens their focus on sensation and submission. Combined with restraints or verbal protocol, this becomes an instrument of total control, not mere penetration.
