Erection Assistant Adjustable Hollow Strap-On by Nasstoys

Erection Assistant Adjustable Hollow Strap-On by Nasstoys is an 8.5-inch hollow extension with an adjustable harness made to add length and girth while keeping you connected to sensation. The hollow chamber lets you stay involved during partnered play while delivering reliable performance. It suits men seeking confidence and couples exploring improved intimacy together.

The product itself

Erection Assistant Adjustable Hollow Strap-On by Nasstoys combines a realistic silicone extension with a wearable harness system that lets you add 8.5 inches while remaining physically connected to the action. Unlike basic sex toys that create distance, the hollow chamber wraps around you, so you feel pressure and grip through every movement. The adjustable straps distribute weight evenly across your waist, staying secure during sustained use without digging in.

The silicone body is non-porous, warming naturally against skin and delivering a realistic feel. The hollow design is the core difference—you slip inside, and the extension does the work whilst you retain full sensation and control. This keeps both partners engaged rather than creating a one-way dynamic.

What stands out

• Hollow chamber design: You stay connected to every sensation whilst the 8.5-inch extension adds length and girth you control completely.
• Wide harness fit: Adjustable straps accommodate waist sizes 29 to 59 inches, so sizing stays comfortable across different body types.
• Non-porous silicone: Body-safe material feels warm and realistic, cleans without harbouring bacteria, and requires no special products.
• Secure, padded straps: Adjustable fastenings lock everything in place during movement without chafing or slipping mid-session.
• Dual benefit: You gain confidence in performance length whilst your partner feels the improved stimulation of added girth and reach.

How to use an adjustable sex toy

Start by adjusting the harness straps to fit snugly around your waist—not tight, just secure enough that it won't shift. Step into the harness as you would underwear, then guide yourself into the hollow chamber carefully. Apply water-based lubricant inside the cavity and along the base; this reduces friction and improves sensation for both partners. Once seated, tighten the straps firmly but not uncomfortably, ensuring the extension sits at the angle that feels natural for your body.

During use, you control rhythm, depth, and intensity just as you would during penetrative sex. The hollow design means you feel grip and pressure through the silicone walls, keeping you engaged. Communicate with your partner about comfort and pace—start slowly, especially on first use. After each session, clean the inside and outside thoroughly with mild soap and warm water, then air dry completely. Store in a cool, dry place away from direct heat or sunlight. Bouncy Sex Balls can be used alongside this toy for added stimulation if desired, though they are optional.

Care and storage

Wash the entire device with mild soap and warm water immediately after use, paying special attention to the interior of the hollow chamber where lubricant and bodily fluids collect. Use a soft cloth or your fingers to clean inside thoroughly, then rinse until no soap remains. Pat dry with a clean towel and leave to air dry completely in a cool spot before storing. Store in a drawer or box away from heat, sunlight, and other silicone toys that might stick together. Inspect the straps and fasteners regularly for wear; they should be replaced if they no longer hold a secure fit.

What to expect

The first thing most users notice is how secure the harness feels once adjusted properly. Unlike extensions that slip or shift, the straps lock you in place, so you can focus on rhythm and connection rather than constant repositioning. The hollow chamber takes a moment to get used to—you are inserting yourself rather than wearing something external—but most people find the sensation of being gripped whilst extending your reach becomes intuitive within the first session or two.

Initial comfort depends heavily on fit and lubrication. Too little lubricant and the silicone can feel sticky or cause friction; too much and control becomes harder. Water-based lubricant is essential—silicone-based products will degrade the dildo over time. Start with moderate lubrication and adjust based on what feels right for your body and your partner's comfort.

Cleaning the interior requires attention. The hollow cavity traps moisture and residue, so thorough drying between sessions matters. A damp or incompletely dried interior will smell or harbour bacteria quickly. Most users develop a rhythm of washing immediately after use, then leaving it to air dry overnight before storing.

The harness itself is durable if cared for, but velcro fasteners wear out with repeated washing and tightening. Check the straps every few months; if they no longer hold a secure fit, they can usually be replaced without buying a new toy. The silicone body itself lasts for years if kept away from heat and stored properly.
