I recommend it for a pair who want to try double penetration without getting out a full harness. The two rings stabilise the dildo against the cock, letting the wearer keep their rhythm and erection as a reference point. The 2.8 cm diameter remains accessible, but it still calls for lube and communication.
Discover the shared-play potential of Cobi Onyx. This black silicone double-penetration dildo is worn directly on your cock thanks to its integrated double cock-ring system. You penetrate your partner while your own cock is stimulated and the dildo adds 13.5 cm of extra insertion.
A base worn like a double cock ring
Cobi Onyx stays in place with two rings: one at the base of your cock and the other around your testicles. This system keeps the dildo stable and aligned along your shaft. As well as providing hot double penetration, it supports your erection by restricting blood flow, making you harder and longer-lasting.
The dildo adds 13.5 cm of insertable length
The insertable part measures 13.5 cm with a 2.8 cm diameter. It is a practical size for filling your partner without being too intimidating. As you thrust, the dildo works alongside your cock, multiplying internal sensations. It is a practical cock ring for exploring double penetration without a bulky harness.
Onyx silicone: flexible and realistic
Made from high-quality silicone, Cobi Onyx is both firm and flexible. Its smooth surface and sculpted glans offer realistic, ultra-comfortable sensations. It follows the movement of your hips for a fluid, natural experience. Easy to clean with warm water and soap, so it is ready for your next session.
