A simple, electrifyingly pleasurable Extension Sleeve from the good Doc Johnson, the Cock Master instantly adds a stunning 5 inches (13cm) of length plus some exaggerated texture and a little extra thickness. Slipping easily over the penis, the Cock Master fully surrounds tip and shaft in soft comfort- the all-encompassing design doubles as a stamina tool, leaving no sensitive skin exposed.

Hollow on the inside to about midway, the top half of the Master is firm yet plush, inspiring a natural sensation on a playmate's end. Add some water based lube to the interior of the sleeve as well as the penis to slide into place, natural suction should hold it nicely stable.

In a safe, phthalate free PVC enhanced with Doc's signature SilAGel, the Cock Master cleans easily swished through some warm soapy water. Most compatible with water based lubricants. Total length is just over 10 inches (25.4cm), inner diameter is approximately 1.5 inches/3.8cm (5.25 inches/13cm circumference).
