Ms Ass Vault Locking Steel Ass Expander

The ATMS Ass Vault Locking Steel Ass Expander is a premium, industrial-style anal toy designed for experienced users seeking intense, secure bondage sensations. Crafted from durable, non-porous stainless steel, this piece offers a unique expanding mechanism that allows for a customizable fit before locking the device securely in place.

This serious piece of hardware features a tapered tip for comfortable insertion, followed by the use of a flat circular key to adjust the metal petals. Once expanded to the desired diameter, the petals are locked using a gold pin key, ensuring the device remains immobile and provides a constant, downward pressure on the rectum. The substantial weight of the stainless steel creates a heavy, grounding sensation that is impossible to ignore.

Material safety is a top priority, as the body-safe stainless steel is compatible with all types of lubricants, including silicone-based options. The design includes a slim neck and a wide, flared base to prevent accidental internal passage, while the temperature-sensitive metal allows for warming or cooling to enhance the sensory experience. Proper care is essential, as the device can be thoroughly cleaned by boiling or using isopropyl alcohol, making it easy to maintain hygiene between uses.

• Material Composition: The device is constructed entirely from high-grade, nickel-free stainless steel, ensuring it is non-porous, durable, and safe for intimate contact without harboring bacteria.
• Expanding Mechanism: Utilizing a flat circular key, users can turn the mechanism clockwise to close the petals or counter-clockwise to expand them, allowing for precise control over the girth and depth of the sensation.
• Secure Locking System: A gold pin key is used to lock the petals in place once the desired expansion is reached. This feature prevents the device from retracting or moving, creating a true anal bondage experience where the user remains fixed in position until unlocked.
• Dimensions and Weight: With an overall length of 3.4 inches and an insertable length of 2.8 inches, the plug expands from 1.5 inches to 2.2 inches in diameter. The unit weighs approximately 9.3 ounces (264g), providing a significant heft that adds to the intensity of the fill.
• Insertion and Removal: The tapered tip facilitates easier entry, while the wide base ensures safety. Removal requires the insertion of the appropriate key into the base and turning counter-clockwise to unlock the pin, allowing the petals to contract for safe extraction.

Usage involves warming the metal with warm water for a more pleasant sensation before insertion. Once inside, the user expands the petals gradually, stopping only when a comfortable level of tension is achieved, before engaging the lock. It is crucial to keep both keys safe and secure, as losing them would make removal impossible. This toy is ideal for those who enjoy partner play, serving out, or exploring the psychological and physical aspects of being locked into a backdoor position.
