This locking expansion plug allows you to open it up inside your partners anus and then secure it in place! While closed, push the smooth, hard plug into their hole. After it is fully inserted, pull back on the stem that protrudes from the base. The three prongs inside your plaything will blossom, stretching their ass open! Once the stem has been retracted enough to expose a hole through it, slide the lock in to keep the plug open. Made of stainless steel, this plug is non-porous and phthalate-free. Use with any lubricant of your choosing. Clean thoroughly after each use with soap and warm water.
