What it is

Rocks Off Union Black is a couples' cock ring engineered for dual stimulation during partnered sex. The stretchy silicone ring fits comfortably over the penis and testicles, while two removable bullet vibrators deliver intense sensation to both partners. One vibrator targets the clitoris; the other stimulates the testicles or perineum. The design enhances blood flow for firmer, longer-lasting erections while the vibration patterns intensify pleasure for both of you.

What sets this ring apart is its dual-vibrator architecture and seven distinct vibration modes—from gentle pulses to sustained intensity. Crafted from hypoallergenic silicone, it's smooth, easy to clean, and safe for all skin types. The waterproof construction means you can explore it in the shower or bath.

How to use a cock ring

Begin by stretching the silicone ring gently over your penis and testicles, ensuring a snug but comfortable fit. Insert fresh batteries into each bullet vibrator, then position one against the clitoris and the other against the testicles or perineum. Press the power button to activate your chosen vibration setting. You can adjust intensity during foreplay and intercourse to match your rhythm and pleasure.

Experiment with different vibration patterns to discover what works best for both partners. The ring's elastic design supports firmer, longer-lasting erections while the vibrators deliver sustained sensation. Try wearing the ring alone during foreplay, then add vibration during penetration. Explore various positions that maximize contact between the vibrators and sensitive areas. See the full BDSM Australia range of Cock Pump Accessories if you want to layer additional stimulation into your sessions.

Always use water-based lubricant to enhance comfort, clean the silicone and bullets thoroughly with warm water and soap after each use, remove batteries between sessions, and go slowly when first wearing the ring to ensure proper fit and circulation. 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

Clean both the silicone ring and bullet vibrators with warm water and mild antibacterial soap after each use. Pat dry thoroughly. Remove batteries from the vibrators and store them separately to prevent accidental discharge. Keep the device in the provided storage bag away from direct sunlight, heat, and extreme cold. Store in a cool, dry place to maintain material integrity and longevity.

Mistress Athena's training notes

This device excels as a control tool in my practice. The dual vibrators allow me to overwhelm my submissive's senses precisely, maintaining complete command over their arousal level. By adjusting intensity mid-scene, I demonstrate my authority while they remain vulnerable and responsive to my choices.

Positioning matters enormously. Strategic placement of each vibrator creates intense focal sensations that break down mental resistance quickly. My submissives report feeling utterly exposed and dependent on my control of the settings—exactly the psychological dynamic I cultivate.

The waterproof rating opens training scenarios I couldn't explore before. Shower scenes introduce unpredictability and heightened vulnerability. Combined with bondage restraints, the ring becomes a sophisticated instrument of sensory manipulation and obedience training.
