Black Silicone Harness Dong Set — Body Extensions Be Strong 2-Piece by Doc Johnson

Black Silicone Harness Dong Set User Guide & Play Styles

Using this harness-compatible dong set for the first time as a couple

For couples stepping into strap-on play, the slim dong profile is a thoughtful starting point — the 4–7-inch length range delivers presence without being overwhelming. Adjust the one-size elastic harness until it sits snug, apply water-based lubricant to the silicone dong generously, and go at whatever pace feels right for both partners. Doc Johnson includes full instructions in the box, so the setup is genuinely straightforward. The unisex harness works across body types, making this couples pleasure option inclusive by design. For more context on strap-on styles, our how-to guide for strap-ons covers the basics. Clean the silicone attachment thoroughly before and after each session — the material is non-porous, so warm water and a toy cleaner handle it easily.

LGBTQ+ couples and anatomy-inclusive penetration play

The Body Extensions system was designed so that anatomy is never a barrier to penetration play. Whether one or both partners want to explore giving, the black silicone harness dong set adapts. The harness-compatible O-ring secures the slim dong in place, keeping movement fluid and confident. Because the silicone dong is solid and body-safe, it’s also compatible with most condoms — a practical consideration for shared-toy hygiene.
