Master Series Inertia Flexible Cum Thru Penis Plug creates deep urethral arousal through flexible medical-grade silicone that adapts to your cock's natural shape. This hollow adult toy allows normal cum flow while delivering direct pressure against sensitive urethral nerves for satisfying edging sessions.

What It Does

This adult toy slides into your urethra to create direct contact with nerve endings that standard external stroking cannot reach. The hollow design maintains normal function while the flexible silicone shaft applies gentle pressure against urethral walls. Unlike basic solid plugs that block flow completely, this allows natural cum release while maintaining arousal throughout your session. Two interchangeable cock rings provide secure positioning without cutting circulation or causing discomfort during extended wear.

The sensation builds gradually as the silicone warms to body temperature and settles into position. Users report heightened sensitivity lasting 30-45 minutes after removal, making subsequent stroking sessions more powerful. Many people find their orgasm quality improves significantly when using this for edging practice, as the constant gentle pressure keeps arousal levels elevated without pushing toward immediate release.

Technical Specs

  • 4.2 inches total length with 3.75 inches insertable
  • 0.3 inch diameter shaft for comfortable insertion
  • Medical-grade silicone with stainless steel components
  • Two interchangeable head rings (1.2 inch and 1 inch diameter)
  • 0.9 inch ring arm for optimal positioning stability

How To Use It

Clean thoroughly and apply water-based lube before slowly inserting the silicone shaft into your urethra. Start with just the tip to gauge comfort, then gradually work deeper as your cock adjusts. The flexible material will conform to your shape while the cock ring sits against your glans for secure positioning.

Build arousal through normal stroking while the plug maintains constant urethral contact. Adjust ring size if needed for comfort during extended sessions. The hollow design allows you to cum normally when ready, creating unique dual sensations as fluid passes through while pressure remains against nerve endings.

Who It Suits

Perfect for cock owners seeking advanced urethral play beyond basic external touch. Ideal if you enjoy edging sessions and want consistent arousal maintenance without hands-on effort. The medical-grade materials suit sensitive users, while the hollow design works well for those wanting normal function during play. Best for experienced users comfortable with urethral insertion, though beginners can start gradually with the flexible silicone construction.

Expert Review from Our In-House Tester

My first time required patience and plenty of lube, but the flexible silicone made insertion surprisingly comfortable once I relaxed. The initial contact creates a unique fullness that's completely different from external stroking. After five minutes, the warming silicone settled into perfect position while the cock ring kept everything secure. Normal stroking felt amplified with constant urethral contact, creating layered sensations I hadn't experienced before. Edging became effortless as the plug maintained arousal without pushing me over the edge. When I finally let myself cum, the dual sensation of fluid passing through while maintaining pressure was incredible. Even twenty minutes later, my cock remained more sensitive than usual. The hollow design means no awkward removal mid-climax, and cleanup was straightforward with the medical-grade materials.
