7-Function Vibrating Plug with Wireless Remote
Add a whole new layer of pleasure for the wearer. The vibrating plug locks into the Vac-U-Lock mount and delivers internal stimulation while your attachment is in use. With the wireless remote, you or your partner can switch between 7 vibration functions anytime, without stopping or repositioning.


Converts to an O-Ring Harness
One harness, every kind of toy. Three interchangeable O-rings let you switch from Vac-U-Lock mode to a classic O-ring harness in seconds, so you can use any flared-base dildo you already own. Choose the ring size that fits your toy snugly for a secure, stable hold.
Breathable Neoprene, Cushioned Comfort
Comfort that lasts as long as you do. The harness is made from soft, breathable neoprene that flexes with your body, while cushioned front and back panels prevent rubbing during extended wear. The open panel design gives full access without taking the harness off.


Dual Stimulation for Couples
Built for shared pleasure. While your attachment delivers for your partner, the vibrating plug gives the wearer their own sensations at the same time. Hand the remote to your partner and let them take control for a playful, connected experience you both enjoy.
