There’s a moment – somewhere between switching on the KIIROO Onyx+ and the first slick stroke – when the line between fantasy and reality blurs so completely, you almost forget you’re alone. That moment is what this machine sells, and depending on your size, kink, and curiosity, it might just deliver the most surreal, mechanical pleasure of your life.

Let’s not beat around the bush: the Onyx+ doesn’t look like a stroker. It doesn’t try to. Encased in glossy black ABS plastic with a matte finish that’s as stylish as it is inconspicuous, it resembles a Bluetooth speaker or a modern thermos. Nothing about it screams “sex toy” – until you uncap the end and peer into the hungry silicone abyss.

But this is no squishy, sloppy, squelching pocket pussy. Inside the Onyx+ lies a dastardly gauntlet of ten contraction rings, ready to pulse up and down your shaft at a dizzying 140 strokes per minute. Controlled manually, remotely, or synced with juicy interactive porn, it’s a smart device in every sense. Call it your dick’s personal trainer, virtual lover, and robotic tease, all rolled into one palm-filling unit.

Still, for all its polished tech and long-distance potential, the Onyx+ is a niche device. And, as with all niche tools, what it offers is nothing short of extraordinary – but only if you fit the mold.

This machine demands commitment. Not just financial – the price tag is north of $200 – but emotional, technical, and anatomical. The standard sleeve accommodates penises with diameters of 3.5 to 4.3 cm. If you’re smaller, you’ll need to buy a separate tight-fit insert. If you’re girthier? Well, your personal hot dog won’t be expanding to premium tubesteak, and your part boner will be deliciously squashed as well as suctioned.

a showstopping dungeon toy!

And this unintended design flaw might be exactly what you’re looking for in your BDSM scenarios. With sufficiently large cocks, this device turns from a smooth masturbator into a devious chastity, edging, and orgasm denial device of evil frustration! Combine that with judicious ball-crushing and a nice violet wand zap to the crack, and it’s a showstopping dungeon toy! Mistress Desdemona agrees. The sad twitches of poor sub Martin’s once-eager cock back it up.

The sensations when it fits are thrilling in a way no human mouth, hand, sweaty buttock crevice, or praying feet could ever replicate. Imagine being gently milked by an AI machine – one that responds to your porn, your partner’s rhythm, or your finger on a touchpad. The sensations when your cock is compressed like an ugly sister’s foot in Cinderella’s bijou shoe are a perfect blend of anticipation, pleasure, desperation, and ultimate exasperation. And it serves the big-cocked cuck right! Right?

But even perfect fits won’t necessarily climax on command – well, not without a perfectly prostate-positioned finger at least. While some men can finish hands-free in five minutes, others report hours of edging. There’s no vibration, no suction, just that rhythmic squeeze-squeeze-squeeze. Is it erotic? Absolutely. Is it enough? Not usually – and that’s where it’s useful in BDSM scenes. Is it enough when Master or Mistress is exerting control? Oh yeah.

it’s like having your cock sucked by a black hole.

Paired with VR, synchronized porn scripts, or KIIROO’s FeelMe AI – which analyzes video in real time to control the stroker – the Onyx+ becomes a sensory extension of the action on-screen. Watch a cam model ride a dildo on Chaturbate, and feel her motion mirrored in mechanical precision. Watch a VR blowjob, and feel the lips translated into pulses across your glistening purple helmet. It’s heavenly sci-fi masturbation, and when the stars align, it’s like having your cock sucked by a black hole.

You’ll need to fully charge the 1000mAh battery for four hours to get about one hour of play. Syncing with the FeelConnect app is simple, but any connection hiccup mid-session is frustrating. And there’s a learning curve: from prying open the unit to seat the sleeve (yes, it’s that tight) to cycling through modes, there’s no shirking the fact that this is a machine for tinkerers.

So what’s in the KIIROO Onyx+ Interactive Male Masturbator box?

  • The KIIROO Onyx+ interactive male masturbator
  • One standard-size TPE Superskin sleeve (3.5–4.3 cm diameter fit)
  • USB charging cable
  • Instruction manual (multilingual)
  • Sample packet of water-based lube
  • One-year warranty registration card
  • Protective cap for the opening

What are the KIIROO Onyx+ Interactive Male Masturbator key specs?

  • Device dimensions: 26 × 9 × 8 cm (10.2 × 3.5 × 3.1 in)
  • Max speed: 140 strokes per minute
  • Charge time: ~4 hours
  • Battery life: ~1 hour
  • Weight: 1300g (2.9 lbs)
  • Compatibility: Bluetooth devices, VR porn, interactive videos, FeelMe AI, KIIROO/OhMiBod products

It’s not waterproof, so if you want below sea level blowjobs, you’ll have to make do with an experienced frogman – or the sucky-sucky thing at the end of your municipal swimming pool.

The pros are clear. It’s interactive, immersive, discreet in design, and engineered with long-distance lovers in mind. It’s quieter than most mechanical strokers, reasonably compact, and perfect for those who want to experiment with teledildonics. Plus, it syncs with FeelTechnology-enabled devices, making it ideal for reciprocal stimulation with a partner using the KIIROO Pearl, Fuse, or Esca.

What’s the price of a decent orgasm these days?

It’s not cheap. Add replacement sleeves, lube, and a FeelMe AI subscription, and you’re looking at a high-maintenance luxury device. Yet for users already immersed in digital kink – especially gay couples, cam fans, or fetishists craving remote control – it might be the ultimate solo/partner hybrid. But who cares? What’s the price of a decent orgasm these days?

You might not want to use it every day, and it’s not a quickie go-to glans explosion. But for those long nights when you want tech to take the wheel, need a partner to jerk you off from six time zones away, or your Dom wants to encase your excitement and control your frustrated near-orgasms, it’s unrivaled.

This isn’t a stroker. It’s an experience. A beautifully engineered, demanding, occasionally orgasmic robot lover. And if your body, bandwidth, and expectations align just right, the KIIROO Onyx+ might blow your mind before it blows anything else.

I love kink. I particularly enjoy large anal plugs, expanding inflatables, deep insertions and prostate massages. I've recently branched out into estim for prostate massage and exotic programmable fucking machines. There's nothing like trying it all out on an unsuspecting sub first, male, female or transgender...
