The wide elastic straps will accommodate most sizes, and the attractive thong style back design offers snug maneuverability. You can insert your favorite flared base dildo into one of the included metal O-rings, snap it into place, and you are ready to start penetrating your partner. The back supporting strap offers a more form fitting design that hugs the contours of your body, allowing you to move freely. With the interchangeable rings and snap-in system, you can sway out one of the included rings for your own, for more size options! This harness system is easy to maintain, making this a comfortable yet sexy choice for all your strap on adventures.
