How to use a masturbators and stroker

Apply water-based lubricant generously inside the stroker's textured interior. Insert your erect penis into the opening and begin stroking in upward and downward motions at your preferred rhythm. The ridged interior will massage your shaft with each movement, building sensation. Vary your speed and pressure to find what feels best. In the shower, rinse the stroker during use to maintain lubrication and cleanliness. Continue until you reach orgasm or stop when you choose.

For extended sessions, combine multiple IKU sleeves using the modular click system to experience varied textures along your penis's length. Try temperature play by running the stroker under warm water before use to enhance sensation. Alternate between different IKU styles to prevent desensitization during longer masturbation sessions. Pair the stroker with a cock ring to intensify erections and prolong play. Explore Realistic Masturbators for other options that deliver lifelike sensations. Practice edging by stroking to near-orgasm, pausing, then using the textured ridges for sustained stimulation without climax.

Care and storage

After each use, remove the silicone sleeve and rinse thoroughly with warm water and mild soap, paying special attention to the textured ridges where lubricant can accumulate. Allow the sleeve to air dry completely before reassembling or storing. Keep the stroker in a cool, dry location away from direct sunlight and heat. Use only water-based lubricants to maintain material integrity. Store separately from other toys to prevent material degradation.

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 flex stroker has become essential in my cock control training protocols. Its textured ridges intensify sensitivity during extended masturbation sessions, making submissives far more responsive to my commands and denial. The modular click system allows me to customize their experience—alternating between different IKU styles keeps them perpetually on edge, unable to predict or adapt to sensations. Combining the stroker with cock rings during training creates intensity that breaks down resistance quickly.

I employ this stroker strategically in humiliation scenes, forcing submissives to stroke themselves while I observe and verbally guide them toward obedience. Waterproof design enables supervised shower masturbation, where vulnerability compounds their psychological submission. My most effective protocol involves forced stroking sessions where I dictate rhythm and timing, repeatedly bringing them to the edge then denying release—this cycle deepens their association between pleasure and my control.

Extended use of the stroker under my direction creates a feedback loop where physical stimulation amplifies psychological dependence. I've observed that submissives who regularly use it during training develop stronger fantasies about my presence, even during solo sessions. The stroker's realistic sensation makes denial more potent—they crave the sensations I've conditioned them to experience only under my permission. I integrate it into long-term training arcs, using its intensity to accelerate their descent into deeper submission.
