Locking Anal Expander — Ass Vault by XR Brands

Locking Anal Expander User Guide & Play Styles

Using the metal anal expander for advanced solo sessions

Start with the stainless steel locking anal expander fully contracted. Apply generous lubricant to the tapered tip and ease it into place slowly — the under-4-inch length keeps insertion manageable even for intensive sessions. Once comfortable, use the flat circular key to open the metal petals gradually, expanding only to what feels right. The substantial weight of the metal build creates a satisfying, constant pull you stay aware of throughout the session. When you’ve found your level, engage the gold pin key to lock that position. The petals won’t shift until you unlock them. Keep the keys within reach — you’ll need them for release. For a deeper look at preparation and technique, read our guide to anal sex.

Temperature play and material care with the advanced anal expander

The silver stainless steel construction of this XR Brands locking anal plug responds beautifully to temperature. Run warm water over the metal before insertion for a more comfortable, gradual sensation — the material holds warmth long enough to matter. Because the metal is non-porous, cleaning is straightforward: boil in water with cleaning solution or wipe thoroughly with isopropyl alcohol. Always wash before and after each use. Compatible with silicone, water-based, and oil-based lubricants, the advanced anal expander leaves your lube choice open.
