Oxballs MasterJack Double Penetration Stroker - Jo Black Ice

Crafted from soft, blubbery Plus+SILICONE with a suede finish, this black masturbator offers a substantial feel. Its design caters to users seeking a thick, fleshy stroker with varied sensations for solo play.

Common Questions

How do I clean the MasterJack stroker?

Cleaning is straightforward. After use, apply a mild soap and warm water to thoroughly cleanse the interior and exterior. Rinse completely and allow it to air dry before storing. Ensure it's fully dry to maintain the silicone's integrity.

Is this stroker suitable for beginners?

The MasterJack is designed for those who crave a thick, fleshy stroker with dual textures. Its substantial feel and intense stimulation might be more suited to experienced users rather than absolute beginners seeking simpler options.
