The problem with sexual performance is that there's never been an effective way to train... until now. The Endurance Jack comes with a specialized masturbation sleeve designed to challenge your longevity. You won't be able to resist shooting your load, but the longer you can train yourself to endure, the longer you'll be able to maintain with the real thing. Endure with this jack and you'll be a legend in the sack! The Endurance Jack comes with the signature silver case. The Fleshjack contains an interchangeable masturbation sleeve which is encased in a sleek container that resembles a large flashlight, allowing for simple and discreet storage. The masturbation sleeve inner portion is made from a patented material called SuperSkin, which is famous for its ability to replicate the sensation of penetrative sex through various orifices such as the mouth or anus. The biggest difference between the Fleshjack and all other masturbation toys in the market, is its incredibly realistic feel, attention to quality, and ease of use. The Fleshjack is a high-quality product which is made in the USA, and, with proper care, will give you a lifetime of enjoyment. Getting head is great but if anal sex is more your thing then enjoy the added sensation and resistance of spreading the bubble butt cheeks on the Jack Ass orifice before thrusting into the canal. Bottoms Up! Use with water based lubes only. Sold as an adult novelty only.
