Not surprising the anal hook pix of D has generated a fair amount of interest and curiosity so in the interest of full disclosure to our fans we decided to post some pix of the hook itself. It is stainless steel and polished to a mirror shine. It transmits vibration very well and can be both warmed or cooled for an interesting temperature effect. the snap hook on the end connects to a head harness that included a bit. When she pulls her head fwd it tugs the hook deeper in her ass.
