IKU Tight Mens Stroker by Fun Factory

Stroking solo can feel repetitive and underwhelming without the right sensation. The Fun Factory IKU tight Mens Stroker Masturbator delivers dynamic wave-like pressure that mimics real contact, while its snug 22mm grip and modular design let you customize every session.

What it is

The Fun Factory IKU tight Mens Stroker Masturbator is a hand-operated stroker engineered for serious penile stimulation. Its defining feature is the wave-like internal texture that creates dynamic pressure variations as you stroke, combining grip and release to build intense sensation. The 22mm diameter opening sits snug around your shaft, delivering realistic skin-to-skin contact without requiring batteries or charging. Body-safe silicone construction remains durable through regular use while staying soft and responsive to your movements.

What separates this masturbator from standard strokers is the Magnetic Click System, a modular frame that lets you swap sleeves and mix textures without buying entirely new toys. You can customize your experience based on mood and desired sensation. See the full BDSM Australia range of Masturbators to explore other options.

How to use a masturbators and stroker

Start by applying water-based lubricant generously inside the sleeve opening and along your erect penis. Insert your shaft into the 22mm opening, allowing the wave texture to grip naturally. Begin stroking with steady hand movements, varying speed and pressure to discover what intensifies your pleasure. The snug diameter creates natural resistance, so control your depth and intensity through hand movement. Experiment with twisting motions and rhythm changes to maximize sensation. Continue until you reach orgasm or your desired satisfaction level, then remove and rinse thoroughly with warm water and mild soap.

For extended sessions, combine this stroker with other male sex toys or incorporate it into partnered play and dominance scenarios. The waterproof design allows shower masturbation, adding temperature play when you alternate between warm and cool water. Pair it with cock rings to intensify erections and prolong arousal during longer sessions. Explore Fleshlight Masturbators if you want to compare different stroker styles and textures.

Care and storage

After each use, immediately rinse the removable sleeve with warm water and mild soap, ensuring complete removal of lubricant residue. Allow the silicone to air dry completely before reassembling with the magnetic frame. Store in a cool, dry location away from direct sunlight and heat sources. The silicone remains compatible with all water-based lubricants, but avoid oil-based products that degrade the material over time.

Mistress Athena's training notes

By Mistress Athena — professional dominant and kink educator, sole instructor behind BDSM Australia's library of training videos. Read her full bio →

The Fun Factory IKU tight Mens Stroker Masturbator has become central to my dominant practice with male submissives. When I command a sub to stroke using this toy, I observe their physical responses intenselytheir breathing acceleration, muscle tension, the way their cock responds to each wave. The snug 22mm diameter serves as a psychological control tool; I explain that the tight grip mirrors my command over their pleasure and orgasms. Denying climax while they stroke builds desperate submission, and I frequently make them edge repeatedly, bringing them to the brink before commanding them to stop.

My most effective technique involves extended denial training where submissives must stroke for specific durations without cumming, building frustration and obedience under my voice alone. Bondage scenarios amplify this—restraining their hands partially while they grip the stroker limits their control and deepens psychological dependency on my commands. The waterproof design allows me to incorporate temperature play, alternating warm and cold water to create contrasting sensations while they stroke. I've developed a progression system where new submissives begin with basic stroking under observation, then advance to edge training where they approach orgasm only at my instruction.

Humiliation work paired with this masturbator deepens psychological submission significantly. Having submissives describe their sensations explicitly while I watch, or forcing extended masturbation sessions that become uncomfortable, teaches obedience through physical exhaustion. The Magnetic Click System allows me to swap sleeves unexpectedly, keeping them uncertain and heightening vulnerability during training. Different submissives respond distinctly—some become vocal and pleading, others achieve meditative focus on my voice. My favorite extended scenes last hours, with the submissive maintaining an erection in the stroker while I control stimulation through verbal commands alone.
