The super soft and stretchy SilaSkin™ material provides an ultra-real feel.

Product Details:

  • Materials: SilaSkin™ provides softness & stretch.
  • 4” long sheath adds .5” width or 1.5" circumference girth
  • The scrotum loop gives a pleasurable tug while stroking or penetrating.

Here’s how it works:

Water-based lubricants can dry out or become tacky over time, especially during longer sessions. That’s because the water in the formula slowly evaporates with friction and exposure to air. Instead of reapplying more lube, just add a few drops of water to reactivate the original slipperiness. It instantly restores the glide and smooth feel—no mess, no waste.

Pro tip: Keep a small cup of water or a spray bottle nearby during play. A light sprinkle or mist is usually all it takes to bring your lube back to life.

Recommended!

First time trying it and it does not disappoint. Great addition to the bedroom for both me and the wife. I was surprised how it still feels great even how thick the material is. Just make sure you use enough lube outside so she doesn’t get sore and not too much inside.

Decent product

It does stretch a bit, but if you are too much thicker or longer may have problems fitting.
