Complete your anal fetishes with the Hollow Anal Dilator. This anal plug is made of Aluminum Alloys.  It is non-porous and compatible with any lubricant.  Once inside. you can explore by probing with whatever can fit inside its hollow diameter. 

A lube shooter can also be inserted to add more lubricant.  Its neck is slightly slimmer than the plug for a comfortable fit between the anal sphincter.  Its wide rim keeps the toy anchored from going all the way in.
