Description

The Master Series Ass Vault Locking Ass Expander is a premium stainless steel anal device designed for experienced users seeking intense, customizable fullness and power exchange dynamics. Featuring a unique locking mechanism, this tool allows users to expand internal petals for a dilator-like sensation and secure them in place, making it an ideal choice for advanced anal play, bondage, and sensory exploration.

Crafted from high-grade, non-porous stainless steel, the Ass Vault offers a substantial, heavy feel that provides a constant, satisfying downward pressure on the rectum. The device is engineered for durability and hygiene, being fully compatible with all types of lubricants, including silicone-based options, without degrading the material. Its temperature-responsive nature allows users to warm or chill the steel prior to use, adding an extra layer of sensory intensity to the experience. The tapered tip ensures easier initial insertion, while the slim neck and wide, flared base anchor the device safely, preventing accidental slipping inside the body.

What sets the Ass Vault apart is its dual-key locking system. A flat, circular key is used to expand the spring-loaded metal petals from the inside, allowing the user to adjust the internal diameter to their desired level of fullness. Once the preferred expansion is reached, a second, gold-pin key locks the petals in place, preventing them from contracting. This mechanism ensures the device stays securely expanded and locked, providing a consistent, unyielding sensation that is popular in anal bondage and power exchange scenarios. The locking feature requires careful handling, as both keys must be kept safe to allow for eventual removal and contraction of the petals.

Safety and maintenance are prioritized in the design of this product. The stainless steel construction is easy to clean and can be sanitized by boiling in water or wiping with isopropyl alcohol before and after each use. Users are advised to use ample lubricant during insertion and to expand the petals gradually to avoid discomfort. The device is not intended for beginners due to its weight, locking mechanism, and expansion capabilities. It is recommended for those who already enjoy substantial anal fill and wish to explore the psychological and physical aspects of being locked in a specific position. The overall length is 3.4 inches, with an insertable length of 2.8 inches, expanding from a base diameter of 1.5 inches to 2.2 inches when fully opened.

A plug that locks you open until you decide otherwise The Ass Vault isn't a starter plug — it's a heavy, locking steel expander built for people who take anal play seriously and like a little power exchange with it. Once it's in, a flat circular key spreads its metal petals open from the inside, creating a deep, insistent fill you can dial to your comfort. Then the gold pin key locks it in place, and that's that: nothing moves until the key comes back out. It's machined from solid, non-porous stainless steel, which means a few things in practice. It works with every kind of lubricant, it's easy to keep hygienic, and it carries real weight — a constant, satisfying downward pull you'll feel the whole time you wear it. Steel also plays beautifully with temperature: warm it or chill it first for an extra layer of sensation. For all its intensity, it's designed to be worn safely. The tapered tip eases insertion, while the slim neck and wide base keep it anchored exactly where it should be, with no worry of it traveling. Cleanup is simple — boil it or wipe it down with isopropyl alcohol before and after each use. This is a premium, advanced toy. If you already love the fullness of a substantial plug and the headspace of being locked and at someone's mercy, the Ass Vault delivers both in one beautifully made piece of steel.
