Description

The Perfect Fit Fat Boy Ultra Fat Penis Sleeve is a thick, clear cock sheath designed to instantly add significant girth and length to the wearer, offering a realistic sensation for both partners. This sleeve features a textured interior lined with pleasure bumps and a smooth exterior, making it suitable for enhancing partner pleasure or functioning as a male masturbator. It is engineered for those seeking a substantial increase in size, with a snug testicle strap to ensure secure placement and prolonged duration.

Crafted from a premium blend of thermoplastic rubber (TPR) and silicone, known as SilaSkin, the Fat Boy Ultra Fat offers an ultra-soft, stretchy, and realistic feel. The material is body-safe and compatible with all water-based lubricants, though it is not compatible with latex. The sleeve is available in two lengths: 5.5 inches and 7 inches, both adding approximately one inch of pure girth to the wearer's natural size. The inner chamber is lined with dozens of tiny nubs that provide massage-like sensations during use, while the exterior remains smooth to facilitate easy insertion for the receiving partner.

Design features include a comfortable testicle strap that keeps the sheath securely in place and adds pleasurable ball play for the wearer. This strap also helps to prolong ejaculation, allowing for extended intimacy. The sleeve stretches to accommodate most penile sizes, with a diameter of 3 inches and a circumference of 5.5 inches. Users report that the material is supple yet thick, providing a natural feel that many find enhances their partner's experience. The device is easy to put on and take off, with reviewers noting its impressive softness and stretchiness.

Proper care involves washing with soap and water or a dedicated adult toy cleaner after each use. It is important to note that this product does not provide protection against pregnancy or sexually transmitted infections. For optimal use, apply a generous amount of water-based lubricant to the exterior to ensure smooth entry. The 5.5-inch length is generally considered ideal for users between 5 to 7 inches in length, while the 7-inch option offers additional coverage. The sleeve's substantial girth may require patience during initial use, but once lubricated, it glides easily, offering a comfortable and pleasurable experience for both partners.

I bought the thick version. It seems heavier than I imagined. When they say 6” or less they mean it. I’m 7” long and it fits kind of awkwardly. The ring that secures it, does stretch enough for me to…

It’s a little on the expensive side but it’s well made. The material is good and you can expect 2 inches in girth. Let’s see how well it holds up over time.
