Make it big - slide into the Jacked Up Thick Extender for increased length and girth. Soft and stretchy to perfectly hug your shaft, Jacked Up Thick stretches eight inches from its ball-teasing base to a firm head in a sheer, frosted material that looks and feels incredible. The extender's ribbed, studded interior stimulates the penis, while the attached ball strap holds it in place and tugs at the balls for added pleasure with every thrust. Kink by Doc Johnson is an exciting collaboration with Kink.com to create a collection of high-quality authentic fetish items suitable for long-term practitioners and new initiates alike.
