Experience the incredible pleasures of a Fleshlight® for yourself with this special bumpy-textured version. Dubbed the STU, or "Stamina Training Unit", it is especially designed to help increase stamina when used on a regular basis. Made of soft and pliable Superskin™ material, this masturbator is also phthalate-free for safe and healthy play. Tucked inside a discreet flashlight style case is a realistic vagina opening, lined with rows of stimulating nubs that treat your erection to amazing pleasure. Twist the cap on the back to vary suction as you slide in and out for a customized experience. Rinse and dry well between uses and pat with cornstarch to maintain lifelike feel, if desired. The Fleshlight® STU vagina comes with a free sample of lubricant.
