Masterjack

How the Masterjack Feels in Use

Heavy in the hand, the OXBALLS Masterjack has a solid, weighty feel before it ever touches your body. This is a thick, heavy-duty double penetration stroker built from soft, blubbery silicone that squeezes and gives like real flesh around the shaft. It is a pro-level masturbator with two separate holes, so you can switch between two very different sensations without reaching for another toy.

Material, Openings and Grip

• Material: Flubbery Plus+Silicone, the softest blend OXBALLS makes, with a pliable feel and a dull suede finish.
• Tight end: A narrower opening lined with ribs and nubs that add texture all along your shaft.
• Loose end: Flip it over for a wider, ringed opening with a relaxed, roomy feel.
• Grip: An integrated handle plus industrial diamond plate texture on the exterior, so it stays put when wet or heavily lubed.
• Build: Hefty and substantial, made for users who want a serious stroking device.

Design & Build

The exterior is as purposeful as the interior. That diamond plate texture is not decorative: it gives your fingers something to lock onto when lube is everywhere. The handle adds leverage and control, which matters on a toy this heavy. You can work it slowly or set a hard pace and still keep a firm hold.

Inside, the two ends offer a real choice. The ribbed, nubby side feels snug and busy. The ringed side opens up and feels spacious and stretchy. Switching mid-session is as easy as turning it around.

Color Options

The Masterjack comes in two finishes. The black version has a bold, dark look that suits its heavy build. The clear version uses transparent material, so you can watch every stroke as it happens. Both share the same thick, dual-hole design and soft silicone feel.
