Hollow Silicone Harness — 6″ Shaft Extender by XR Brands

Hollow Silicone Harness User Guide & Play Styles

Using the silicone shaft extender during partnered penetration

The realistic hollow harness slips over your own anatomy, letting the wearer contribute sensation while adding over 6 inches of length and 1.5 inches of girth. Roll the silicone on gently — never pull — and apply talc-free baby powder or 100% cornstarch first to ease the fit. The 4.8-inch hollow shaft depth and 1.5-inch insertable diameter give the wearer comfortable internal contact, while the receiving partner experiences the full 5 inches of insertable length.

The beige silicone and realistic feel keep the moment natural and uninterrupted — material that cleans easily and feels right.
