Strap-On Harness Kit — Heart-Throb Deluxe by Nasstoys

Strap-On Harness Kit User Guide & Play Styles

Using this adjustable harness kit as a couples first-time strap-on experience

If this is your first time exploring strap-on play together, the one-size adjustable design removes most of the setup friction. Thread the phthalate-free curved dong through the iron O-ring, tighten the polyester straps until the heart-shaped harness pad sits flush and comfortable, and you are ready. The 7″ curved dong’s natural arc makes angling intuitive — no repositioning required mid-moment. Body-safe materials mean you can focus on each other, not on what the toy is made of.

Layering the blindfold and paddle for sensory couples play

Once the couples strap-on kit harness is fitted and comfortable, the included blindfold and 10″ paddle open a second layer of play without any extra gear. The black PVC blindfold (7.5″ × 3″) heightens anticipation by narrowing sensory focus to touch and sound — a simple way to explore trust dynamics together. Keep the paddle within reach to introduce light sensation play whenever both partners are ready. Communication before and during keeps everything easy and enjoyable. The metal O-ring holds the dong securely throughout, so the wearer stays confident and in control. Clean all PVC and polyester components with mild soap and warm water after use; air-dry completely before storing.
