Iku Tighter Male Pleasure Masturbator By Fun Factory

Stroking sessions can feel repetitive and lack the grip you crave. The Fun Factory IKU tighter Male Pleasure Masturbator delivers intense, realistic sensation through its ribbed silicone interior and tight 20mm diameter, while its modular magnetic design lets you customise your pleasure collection.

What it is

The Fun Factory IKU tighter Male Pleasure Masturbator is a hand-held stroker engineered for intense penile stimulation through a tighter, gripping fit. Its ribbed silicone interior delivers authentic skin-to-skin sensation as you stroke, while the body-safe material conforms to your shape without losing structural integrity over time. At 20mm internal diameter, it grips noticeably firmer than standard masturbators, amplifying every stroke. The compact design suits most penis sizes and fits easily in your hand or travel bag.

What sets this masturbator apart is its revolutionary Magnetic Click System—the silicone sleeve detaches from the magnetic base, letting you swap it with other IKU designs to vary texture and intensity whenever you want. The waterproof IPX7 rating means you can use it in the shower, bath, or any wet setting without hesitation.

How to use a masturbators and stroker

Apply generous water-based lubricant inside the sleeve and on your erect penis. Grip the masturbator firmly with one hand and stroke your shaft in and out using steady, rhythmic motions. The ribbed interior activates with each stroke, delivering intense sensation against your shaft and glans. Vary your speed and pressure to match your arousal and desired intensity. Continue stroking until you reach orgasm and ejaculation. The compact design works in bed, on the couch, or in the shower thanks to its waterproof construction.

For extended sessions, pair the IKU tighter Male Pleasure Masturbator with a cock ring to intensify sensation and maintain your erection longer. Experiment with different stroking rhythms and hand positions to discover what feels best. You can swap the silicone sleeve with other IKU models mid-session to experience fresh textures and reset your arousal. For couples, your partner can manually stroke the masturbator around your penis, creating shared pleasure experiences. Explore App Controlled Masturbators if you're interested in hands-free or remotely controlled options for future exploration.

Care and storage

After ejaculation, remove the silicone sleeve from the magnetic base and rinse immediately with warm water and mild soap. Pay special attention to the ribbed interior, ensuring all semen and lubricant residue is completely removed. Pat dry with a soft cloth and air-dry fully before reassembling. Store in a cool, dry location away from direct sunlight and heat. Use only water-based or silicone-based lubricants—petroleum products degrade silicone over time and should be avoided entirely.

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 tighter Male Pleasure Masturbator has become indispensable in my submissive training protocols. When I introduce it to new submissives, the tighter 20mm diameter immediately intensifies their responses, making them acutely aware of their physical arousal under my control. I use the ribbed texture to teach proper stroking technique, demonstrating exactly how I expect their penis handled during supervised sessions. The masturbator's firm grip creates unmistakable physical feedback that allows me to gauge arousal levels and predict approaching climax with precision.

Denial training reaches new psychological depths with this tool. Requiring submissives to stroke themselves to near-climax then stop immediately on my command produces rapid frustration and heightened obedience. The modular magnetic design surprises them mid-session when I swap sleeves unexpectedly, disrupting their rhythm and resetting their mental state. Combined with cock rings, the IKU tighter creates desperate sensitivity that makes submissives remarkably compliant during extended training.

My most effective protocols involve extended edging cycles where submissives maintain constant arousal while I deliver psychological domination through verbal commands and pleasure restrictions. Forcing them to describe every sensation they experience with the ribbed texture deepens their awareness of sexual dependency on my approval. Waterproof construction enables shower domination scenarios that add vulnerability and exposure elements to their training experience.

The realistic sensation this masturbator produces creates powerful physical responses I leverage for psychological manipulation. Submissives become acutely aware that their sexual pleasure exists entirely at my discretion, fundamentally deepening their submission and obedience. This tool has transformed my training effectiveness and submissive development outcomes significantly.
