Obsidian Thrusting Heating Masturbator by Doc Johnson

Stroking alone can feel repetitive and one-note. Obsidian Thrusting Heating Masturbator by Doc Johnson combines seven thrusting, suction, and vibration modes with warming to deliver layered, full-body stimulation that builds in intensity and keeps you engaged.

What it is

Obsidian Thrusting Heating Masturbator by Doc Johnson is an automatic stroker engineered to deliver deep, rhythmic milking sensations combined with pulsing suction, powerful vibration, and warming. The super-squishy TPE sleeve creates a realistic texture that responds to every movement, while independent mode controls let you layer thrust, suction, and vibration together for custom intensity. You can start with a slow, deliberate tease and build toward overwhelming fullness—or find your sweet spot anywhere in between.

Its clear digital display puts every setting at your fingertips, and the body-safe construction ensures safe, comfortable play every time. See the full BDSM Australia range of Masturbators to compare styles and features that suit your needs.

How to use a masturbators and stroker

Apply a generous amount of water-based lubricant to the inside of the sleeve and to your penis. Power on using the digital display, then select your starting mode—begin with lower thrust and suction settings if you're new to the device. Insert gradually and let the automatic strokes do the work; you can thrust in rhythm or hold still and let the machine move around you. Build intensity by layering modes: add vibration mid-session, increase thrusting speed, or activate heating for deeper sensation.

Most users find their rhythm within the first few sessions. Experimentation is key; try different mode combinations to discover what drives you toward orgasm fastest. When exploring stroker options alongside Obsidian, browse the Fleshlight Masturbators range to understand how sleeve design and motor intensity vary across brands. After use, power off, remove the sleeve, rinse thoroughly under warm water, and allow to air-dry completely before storage.

Care and storage

Wash the removable sleeve with warm water and mild soap immediately after use. Avoid harsh scrubbing or submerging the motor housing. Pat dry with a lint-free cloth and air-dry completely in an upright position before reassembling. Store in a cool, dry place away from direct sunlight and heat. Keep the USB cable coiled loosely to avoid damage. Recharge monthly even during storage to maintain battery health.

Mistress Athena's training notes

Obsidian Thrusting Heating Masturbator by Doc Johnson fascinates me because it operates on its own rhythm—something I can weaponise in scenes where control and denial matter most. I use it to bring a submissive to the edge, then dial down the intensity while he remains locked in, forced to feel the machine's pulse without release. The heating function adds psychological weight; warmth becomes a reward for obedience, withdrawn when he breaks protocol.

My favourite setup uses the lowest thrusting mode paired with maximum suction. This combination creates a slow, relentless pull that builds arousal without triggering orgasm—perfect for extended sessions where patience and tolerance are the real test. Watching his helplessness as the device works him while he's bound or instructed to remain still sharpens his focus on my authority. The clear display sits where I can see every mode without him controlling anything.

Temperature play opens new dimensions. I activate the heating function only when he's proven compliance, making warmth contingent on behaviour. Conversely, I've used the device completely cold—removing the reward of heat—to reinforce a day's worth of imposed denial. The textured sleeve means sensation stays unpredictable even on repeat modes, keeping him alert and responsive rather than numb.
