Hollow Strap-On Harness — Master Series Magnum 9″ Silicone Dildo by XR Brands

Hollow Strap-On Harness User Guide & Play Styles

Using a hollow silicone strap-on for pegging and shared-sensation play

Pegging opens a new dimension of intimacy — and the adjustable pegging harness on the Magnum makes the logistics straightforward. Slide into the 5.3-inch hollow shaft, apply a generous coat of water-based lube (always water-based with silicone toys to keep the material clean and intact), then buckle the vegan leather harness snug. The one-size adjustable fit covers 33 to 47.5 inches at the waist, so any body type can wear it confidently. The textured, realistic-feel shaft moves naturally with you, keeping depth and rhythm exactly where you want them.

9-inch hollow strap-on as a size-play and power-exchange tool for couples

Size play and power exchange thrive on confidence — and 9 inches of phthalate-free silicone with a solid 3.6-inch tip delivers it. The XR Brands Magnum is designed for couples exploring the giving and receiving dynamic on their own terms: wear it over or strap it on bare. The black colorway keeps the aesthetic intentional, and the metal hardware on the nylon and leather harness stays secure through the most active sessions. The 8-to-9-inch length range puts this firmly in upgrade territory — best approached with plenty of lube and unhurried pacing.
