DuoSphere Anal Plug and Bondage Hook
The DuoSphere combines a double-beaded sliding steel anal plug with a curved bondage hook. The plug positions anywhere along the hook, and pivoting O-rings at each end let you attach ropes, chains, or other restraint gear for creative positions.

Master Series DuoSphere Anal Plug and Bondage Hook
Overview
The Master Series DuoSphere is a devious pairing of a double-beaded sliding anal plug and a curved bondage hook. The cool steel balls ease in one by one for a gradual stretch, and once the plug is seated you can slide it along the length of the hook to set its position to suit the scene.
Each end of the curved steel bar carries a pivoting O-ring, so you can attach ropes, chains, or other gear to work the hook into a restraint setup. The top bead is removable, letting you choose one sphere or both. As all-steel hardware it warms or cools in water for temperature play, and it pairs naturally with our anal toys and bondage accessories.
Key features
- Double-beaded plug: Two steel spheres ease in one by one for a gradual anal stretch.
- Sliding adjustment: The plug slides along the length of the bondage hook to set its position.
- Pivoting O-rings: An O-ring at each end of the bar accepts ropes, chains, or other bondage gear.
- Removable top bead: Take off the top sphere to use one bead or both, as you prefer.
- Temperature play: Warm or cool the all-steel piece in water before insertion for temperature play.
Steel built for restraint
The curved bar and sliding plug let you combine penetration with positioning, holding a partner in place through the hook while the steel spheres stay seated. Slide the plug to adjust how the hook sits.
With a pivoting O-ring at each end, the DuoSphere ties into ropes and chains so you can build it into whatever restraint arrangement you have in mind.

Materials and construction
The DuoSphere is solid stainless steel throughout. The double-beaded plug and the curved hook are one continuous steel build, with pivoting O-rings set into each end of the bar. Because it is all steel, the piece takes a temperature from water and holds it, and the smooth metal wipes clean easily.

Frequently asked questions about leather restraints
What is a bondage hook used for?
A bondage hook positions and restrains a partner, often by anchoring it to ropes or chains during a scene. The DuoSphere combines that hook with a sliding anal plug and pivoting O-rings, so you can both penetrate and restrain a lover with one steel piece.
How does the sliding plug work?
The double-beaded steel plug eases in one sphere at a time for a gradual stretch, then slides along the length of the bondage hook once seated. This lets you adjust the plug's position on the bar to suit the position and the scene you have in mind.
Can I attach ropes or chains to it?
Yes, each end of the curved steel bar has a pivoting O-ring. The O-rings accept ropes, chains, or other bondage gear, and because they pivot, they move with your setup, letting you build the DuoSphere into a larger restraint arrangement.
Can I use only one bead?
Yes, the top bead of the anal plug is removable. You can choose whether a partner experiences both steel spheres or just one, which makes the plug adaptable to different comfort levels and lets you ease into the fuller double-beaded stretch.
Is the DuoSphere good for temperature play?
Yes, the all-steel build holds temperature well. Warm or cool the DuoSphere in water before insertion for exciting temperature play. The stainless steel takes on the heat or chill of the water and carries that sensation into the scene.
How do I clean a stainless steel bondage hook?
Wash the steel with warm water and a toy-safe cleaner, then dry it fully. Stainless steel is non-porous and wipes clean easily, and keeping the O-rings dry prevents any corrosion. Store the DuoSphere somewhere safe where the steel will not get scratched.
