Looking for a wide but short dildo to gape your hole? 

DualDensity™ by design. Made for tunnel width and second ring expansion.

Bulwark is short, thick, and focused. Its soft tip reaches deeper contact, while the wide body brings strong fullness into the tunnel instead of leaving all the pressure at the entrance.

With a supportive DualDensity™ core and a body that narrows toward the base, Bulwark lets the widest part pass in, settle deeper, and train the space around the second ring with more control.

What is Kikuchi® DualDensity™?

Dual density means two silicone firmnesses in one toy: a softer outer layer with a firmer supportive core.

Compared with other structures, Kikuchi® DualDensity™ Silicone Design allows the head to stay very soft without making the whole toy too floppy. The softer tip and surface make first contact gentler and less poking. The firmer inner core gives the toy enough support to enter more smoothly, stay in place with less slipping out, and move with better control.

If one Kikuchi Toy uses two silicone densities or more, it will be marked as DualDensity™ SILICONE DESIGN on the poster above. Single-density toys will be marked as PLATINUM-CURED SILICONE.

Mr. Kikuchi's Note

When I designed Bulwark, I was thinking about a problem many users meet after the hole itself has already improved.

The hole may open, but the tunnel and the second ring still do not know how to take same width. A long taper can keep stretching the outside again and again, while the deeper area still feels behind. Bulwark was made to bring the challenge inward.

This is why Bulwark is short and thick. I did not want it to feel like a long progression toy. I wanted the body to meet a concentrated width, let it pass the hole, and then feel that fullness settle deeper into the tunnel.

The shape is important. Bulwark is not wide all the way down. The body builds to a strong middle width, then becomes narrower toward the base. After the widest part passes, the hole does not need to stay under the same pressure. This lets the toy sit more inward and makes the deeper tunnel and second ring do more of the work.

Bulwark is best for users whose hole can already take fists, but who still feel tightness, resistance, or pressure deeper inside. It is useful when you want to train internal width instead of only repeating entrance stretch.

For sizing, I would choose based on how your second ring responds, not only what your hole can take. Bulwark L is for users who already understand tunnel pressure and want clearer gradual expansion. Bulwark XL is for users who can open the hole reliably and want strong internal stretch without using a long toy.

Bulwark is advanced. Use Bulwark after warm-up. Use plenty of water-based lubricant and let the soft tip find the path first. Do not rush the wide body. When the widest part reaches resistance, pause and let the tunnel understand the pressure. Once it passes, allow the toy to settle instead of pushing aggressively.

The feeling I wanted from Bulwark is compact, deep, and heavy: not a long slide, but a strong internal opening. It is for the stage of STRETCH where the goal is no longer just getting past the entrance, but teaching the tunnel and second ring to make space.
