Master Series Cock Dock Full Access Tunnel Butt Plug

Hollow Tunnel Plug for Penetration, Gaping, and Total Access Play

The Cock Dock is a hollow tunnel butt plug that keeps your partner's ass spread open and fully accessible during play. Made from semi-stretchy TPE, it's soft enough to fuck through while holding its shape to keep them wide open and waiting.

This one is made for couples, Dom/sub dynamics, medical play, diaper play, enema play, and anyone who wants unrestricted access to their partner's hole without removing the plug.

Specifications

Safety & Care

Cleaning: Wash with warm water and mild antibacterial soap before and after every use. Because this is a hollow plug, rinse thoroughly through the tunnel to clean the inside channel completely. A bottle brush or toy cleaning wand helps reach the interior.

Lubricant compatibility: TPE is a porous material. Use water-based lube only. Silicone-based lube can degrade TPE over time.

Storage: Store in a clean, dry place away from other toys. TPE can pick up lint and should be kept in a pouch or covered container.

Warnings: For anal use only. Always use with enough water-based lubricant for comfortable insertion. The flared base keeps the plug retrievable. Do not use if the material shows any signs of cracking or deterioration. Not recommended for sharing between partners without a condom over the plug, as TPE is porous and cannot be fully sterilized. 

Discreet packaging: Your order ships in plain, unmarked packaging with no reference to the product on the outside.

Who It's For

The Cock Dock is made for couples and Dom/sub partners who want total access to a held-open hole. It's ideal for control and humiliation dynamics, gaping play, diaper and enema scenes, and anyone who wants to fuck through a plug rather than remove it. If you want to keep your sub spread open, helpless, and ready whenever you choose, this plug does exactly that.

Frequently Asked Questions

Can you actually penetrate through the Cock Dock tunnel plug?

Yes. That's exactly what it's made for. The hollow tunnel runs the full length of the plug, and the semi-stretchy TPE is soft enough that your cock slides through comfortably. The internal ribbing stimulates you as you push through, and you feel the transition from plug to flesh when you reach the end.

Will the Cock Dock stay in place during sex?

Yes. The flared midsection and tapered base work together to hold it in place. It stays put during active, vigorous thrusting without needing to be held or repositioned.

What size cock fits through the Cock Dock?

The inner diameter is 1.5 inches, which works out to a circumference of roughly 4.7 inches. The TPE does have some stretch to it, so there is a little give, but this plug is best suited for average to slimmer girths rather than very thick cocks.

Is the Cock Dock good for gaping and training?

Yes. Inserting it regularly over time helps stretch and open the hole progressively. The 2.5 inch outer diameter provides a solid stretch, and the hollow center keeps the opening held wide while it's in.

What lube should I use with the Cock Dock?

Use water-based lube only. TPE is not compatible with silicone-based lubricants, which can break down the material. Use a generous amount on the outside of the plug and around the rim before insertion.

Can the Cock Dock be used for enema or diaper play?

Yes. The hollow tunnel allows full access to the rectum, which makes it a natural fit for enema administration, medical scenes, or diaper play where you want the wearer open and unable to hold themselves. It's one of the few plugs that works as a functional tool for this kind of play, not just a prop.
