Description

The Doc Johnson Body Extensions Be Strong Hollow Strap On System is a versatile, unisex harness kit designed to facilitate penetration play for wearers of all anatomies. This two-piece set combines a durable, adjustable elastic harness with a premium, hollow silicone attachment, allowing for shared intimacy and enhanced sexual empowerment regardless of the user's body type.

Designed with inclusivity and comfort in mind, this system features a jock-style harness constructed from soft silicone and stretchy elastic. The wide waistband is engineered to provide maximum support and stability during vigorous activity, while multiple snap closures allow for a customizable fit for waists ranging from 28 to 48 inches. The harness is designed to sit securely, ensuring that the wearer feels supported and confident throughout play.

The centerpiece of this kit is the 7.5-inch hollow silicone dildo. Unlike traditional solid dildos, this attachment features a hollow interior specifically designed to accommodate a penis, allowing for a shared penetration experience. The silicone is phthalate-free and body-safe, offering a smooth, non-porous surface that is gentle on the skin. The attachment includes tabs that snap securely into the harness, ensuring it stays in place during use while remaining easy to remove for cleaning or storage.

The design of the Be Strong attachment includes a subtle curved cutout on the underside, which can provide targeted stimulation to the G-spot or P-spot. The texture features gentle ripples that add sensory interest without being overly abrasive. With a diameter of approximately 1.6 inches and a width of 1.75 inches, the dong offers a balanced girth that is suitable for both beginners and experienced users. The material is bendable yet sturdy enough to hold its shape, providing realistic feedback during use.

Care and maintenance are straightforward. The silicone components can be cleaned with warm water and mild soap, or a dedicated antibacterial sex toy cleaner. It is recommended to let the product air dry completely before storing it in a cool, dry place, ideally in a storage bag to protect it from dust and debris. Only water-based lubricants should be used with this product to prevent degradation of the silicone material.

This system is part of the broader Body Extensions collection, meaning the hollow attachment is interchangeable with other compatible harnesses in the line. This modularity allows users to mix and match components to create a setup that best suits their preferences. Whether used for solo exploration, couple's play, or gender-affirming intimacy, the Be Strong system offers a reliable and high-quality solution for expanding sexual expression.
