CockBlock Australia - Dual-Entry Masturbators & Frotting Pleasure Devices

CockBlock dual-entry masturbators are designed for two partners to use together, allowing simultaneous penetration and direct cock-on-cock contact within a single chamber. They combine frottage stimulation with traditional penetration in one innovative device.

About CockBlock

CockBlock dual-entry masturbators are designed specifically for couples who want to experience frottage—the intimate practice of rubbing penises together—without losing penetration. The device features two separate entry points that lead into a shared internal chamber where both shafts meet and glide together. Inside, a flesh-like thermoplastic elastomer sleeve provides realistic sensation, while the outer casing is made from soft, squeezable silicone that moulds comfortably against your body.

The internal figure-eight cross-section keeps both penises aligned for maximum cock-on-cock contact throughout use. The heavy construction provides stability during thrusting, while the open-ended design means there's no size limit—all lengths fit comfortably. Sport Fucker and other brands also make dual-entry sex toys, but CockBlock's design focuses specifically on frottage as the primary sensation.

What makes CockBlock different

Most couples toys focus on penetration alone or are designed for one partner to use on another. CockBlock is built around mutual penetration and cock-on-cock stimulation happening at the same time inside the same chamber. The figure-eight internal shape and dual-entry design mean both partners experience direct contact with each other, not just with the sex toy. Spartacus Enterprises makes other dual-entry products, but CockBlock's engineering prioritises the frottage experience above all else.

Types of CockBlock

CockBlock offers several configurations to suit different preferences and body types.

Original CockBlock Dual Masturbator. The flagship model with a soft silicone outer casing and internal TPE sleeve. Comes with one standard sleeve and works for most users.

Regular Sleeve. The softer, more stretchy option that provides comfortable sensation and works well for first-time users or those who prefer a gentler grip. Topco makes textured sleeves for other sex toys, but CockBlock sleeves are designed specifically for the dual-entry chamber.

Tighter Sleeve. A firmer option that delivers increased pressure and grip for partners who want more intensity and sensation during use.

Orbiter Texture Sleeve. Features a textured internal surface with lumps and bumps to add extra stimulation and variety during penetration.

How they compare

How to choose a cockblock

Start by thinking about what you both enjoy. If you're new to frottage or dual-entry sex toys, the Regular Sleeve is the safest starting point—it's forgiving, stretches easily, and doesn't require perfect arousal to enter. If one or both of you prefer a tighter sensation or want more grip around your shaft, the Tighter Sleeve delivers that intensity. The Orbiter Texture Sleeve adds internal bumps for extra stimulation, so choose it if you both like textured sensations and have some experience with couples toys.

Fit is less about exact sizing and more about comfort and arousal. Both entry points should feel snug but not painful; if either partner feels pinched or uncomfortable, you're not aroused enough yet or you've chosen a sleeve that's too firm. The Duo Pack lets you try both Regular and Tighter sleeves, so you can figure out what works for you both without committing to one. Sportsheets makes couples bondage gear that pairs well with sex toys like this if you want to add restraint into the mix.

Buying and fit guide

After years of helping customers choose dual-entry sex toys, we've learned that most people underestimate how much arousal matters. The CockBlock works best when both partners are fully erect and well-lubricated. If you're buying for the first time, don't rush into the Tighter Sleeve just because you think you should be "more intense"—many couples find the Regular Sleeve provides plenty of grip once you're properly aroused, and it's far more forgiving if one of you loses your erection mid-use.

Size isn't really a limiting factor with CockBlock because the open-ended design accommodates all lengths. The real question is firmness. If you're both on the thicker side or prefer a snug sensation, Tighter is worth trying. If you're unsure, Regular is the better gamble. The sleeves separate from the casing, so you can buy the sex toy with one sleeve and upgrade or add another sleeve later without replacing the whole thing.

Lube is essential. Water-based lube works with the TPE and silicone materials and won't degrade them over time. Apply generously to both entry points and inside the sleeve before use. The dual-entry design means you're coordinating two people's movements, so starting with plenty of lube takes pressure off and makes entry smoother for both of you. Clean the sex toy thoroughly after each use by separating the sleeve from the casing and washing both parts under warm water with a toy cleaner or mild soap.

Different ways to use CockBlock

CockBlock is designed for partnered use, but there are several ways to approach it. Both partners can thrust simultaneously, creating friction and contact between your penises. Alternatively, one partner can stay still while the other thrusts, or you can take turns controlling the rhythm. The figure-eight chamber keeps you aligned, so you don't need to think too hard about positioning—just focus on what feels good. Use plenty of water-based lube, and consider adding a vibrator against the outer casing for extra stimulation. The sex toy's weight means it stays stable on a bed or surface if you want hands-free use, freeing you both to touch each other elsewhere.
