Using the Sportsheets Dual-Penetration Desire Strap-On Harness is easy. First, adjust the 4-way adjustable straps to fit your hips comfortably. The harness can fit hips up to 60 inches. Then, choose the O-Ring that suits your needs and attach it. You can use it for dual penetration or to keep a firmer erection. If you want to use a second dildo, simply attach it. Make sure to use the connection strap to securely attach your flared base dildo. When it comes to cleaning, use mild soap and warm water. Gently wash the harness and let it dry completely before storing it. Keep it in a cool, dry place. Always check the O-Rings and straps for any signs of wear and tear before each use. This will ensure your safety and the best performance of the harness.
