Oxballs MasterJack Double Penetration Stroker Jo Black Ice

The Oxballs MasterJack double penetration stroker Jo Black Ice is a heavy, two-ended stroker in Oxballs’ softest Plus+ silicone blend. It has a built-in handle, a matte suede-like finish and a diamond plate grip pattern all over the outside.

The weight and thickness give it a substantial, cushioned feel in the hand.

Two ends of the double penetration stroker jo black ice

One end has a tighter, puckered opening with ribs and nubs inside for detailed texture. Flip it over and the other end opens into a wider, ringed channel for a smoother, looser glide.

Switching ends changes the experience completely, so you have two strokers in one body.

• Two entries with different textures
• Tight end with inner ribs and nubs
• Wider end with rings
• Integrated handle that stays in the hand
• Diamond plate grip texture
• Soft Plus+ silicone with a suede-like finish

The handle means the stroker stays put in your grip, even with plenty of lube.

Use a generous amount of lube in whichever end you choose, and add more as you go. The thick walls keep their shape and spring back between strokes.
