About the Product

Fantasy X-Tensions 20 cm Silicone Hollow Extension is a hollow strap-on extension that the wearer fits over their own penis to add length and girth. The outer layer is super-soft Elite silicone, while the firm hollow interior is lined with a smooth Luv-Touch coating for comfort. Adjustable elastic straps hold it in place, making it a practical option for couples who want to try a larger size or who prefer a strap-on that does not rely on the wearer's firmness.

Key Features

  • Hollow design: Slides over the penis so the wearer feels movement while the extension adds size.
  • Dual-density build: Soft silicone on the outside with a firmer hollow core for control.
  • Luv-Touch interior: A smooth inner coating makes the inside comfortable against the skin.
  • Tapered head: The tip narrows for easier insertion.
  • Wide opening: The 4 cm (1.6 inch) opening accommodates most sizes.
  • Adjustable straps: Stretchy elastic straps fit waists up to 127 cm (50 inches).
  • Lifelike 20 cm shaft: An 8 inch shaft adds noticeable length for partner play.

Why Choose the Fantasy X-Tensions Hollow Extension?

Hollow extensions let the wearer stay involved in the sensation, unlike a solid strap-on dildo. The soft silicone outer feels pleasant for the receiving partner, while the firm core keeps the shape steady during movement.

The one-size-fits-most straps and wide opening mean the extension suits a broad range of body types. It is described as phthalate-free.

How to Use and Care

Apply a little water-based lubricant inside the opening and on the outside of the shaft. Slide the extension over the penis, then adjust the elastic straps around the waist and thighs until it feels secure but not tight. Go slowly at first so both partners can adjust to the size.

This product is not a condom and does not prevent pregnancy or infections. Clean with warm water and mild soap or a toy cleaner, dry fully inside and out, and store away from other toys.

Frequently Asked Questions

Will it fit me?

The 4 cm wide opening accommodates most sizes and the straps adjust to waists up to 127 cm. If you are much wider than 4 cm, the fit may feel tight.

Can it be used as a condom?

No. It is not a condom. Use a separate condom underneath if you need protection, and a new one on the outside when sharing.

Which lubricant should we use?

A water-based lubricant is the safest choice with silicone. Silicone-based lubricants can damage some silicone surfaces.

Is 20 cm large for a first strap-on?

It is a generous length. Take your time, use plenty of lubricant and communicate with your partner about comfort.
