Perfect Fit Fat Boy Penis Extender Sheath

A penis extender sheath is a hollow strap-on that adds girth and length to your penis. It is also excellent if you have trouble staying erect or to use as a masturbator.

This ultra-real feeling sheath is super strong and gives your penis that extra girth or length without it being too large for your partner. 

It is very easy to get on and off and stays in place by hooking onto your scrotum with the opening hole at the base of the sheath. This also gives you a pleasing pull on your scrotum for more pleasure during masturbation or penetration.

The Fat Boy Penis Extender Sheath also makes a great stroker and masturbator with its nubs and ribs and soft cushioned feeling on the inside. Just add water-based lubricant on the inside and you are ready to go!

Available sizes:

  • Thin Standard 5.5" | Most men (max 6” penis) to add noticeable girth (1/2”-3/4”)
    • Snug fit
  • Sport 6.5" | Most men (max 6” penis) to add maximum girth (1”+)
    • Snug fit

It is made of Silaskin, which is a mix of Silicone and TPR which gives it an amazing stretch ability. This penis sheath is not too hard like some other penis sheaths on the market.

Wash thoroughly with mild soap and water or sex toy cleaner.
