What it is

Kaitai Shinso: Internal Structure of a Moe Body is a precision-engineered masturbator built on groundbreaking anatomical design. Its four-layer construction mimics human internal structures—ribcage, spine, pelvis—with a soft gel exterior and firm skeletal core. Each layer delivers distinct textures as you move, creating sensations that adapt to your rhythm and pressure. This approach sets it apart from standard strokers, which typically offer uniform ridging or simple texturing.

The device uses Magic Eyes' proprietary medical-grade synthetic material, engineered for both realism and durability. Its substantial 270mm length provides room for full-body engagement. See the full BDSM Australia range of Masturbators to compare other options, but this model's skeletal internal design stands alone in delivering hyper-realistic anatomical feedback.

Key features

  • Four-layer structure: Soft exterior, textured membranes, and bone-like core create layered, evolving sensation with every stroke.
  • Anatomical skeleton: Internal ribcage and spinal design mimic human anatomy, delivering realism that standard ridged strokers cannot match.
  • Substantial size: 270mm length and 165mm width provide comprehensive stimulation and realistic proportions for extended sessions.
  • Medical-grade material: Hypoallergenic, body-safe synthetic resists degradation and maintains texture integrity through regular use.
  • Manual operation: No batteries or electronics—complete control over speed, depth, and pressure remains entirely in your hands.

Specifications

  • Dimensions: 270mm length, 165mm width; weighs approximately 350–400g when filled.
  • Material: Magic Eyes proprietary medical-grade synthetic; hypoallergenic and phthalate-free.
  • Internal structure: Four distinct layers—soft gel skin, textured membrane, firm support layer, and skeletal core mimicking ribcage, spine, and pelvis.
  • Power: Manual operation; no batteries or power source required.
  • Waterproofing: Splash-resistant exterior; interior can be rinsed under running water.
  • Box contents: Masturbator unit, discrete packaging, care card; lubricant sold separately.

How to use a masturbators and stroker

Start by applying generous water-based lubricant to the opening and your penis. Insert slowly, allowing the soft exterior to stretch around you. Feel the textured layers engage as you push deeper—the internal membrane and skeletal structure will create distinct sensations at different depths. Begin with slow, deliberate strokes to explore the device's range; you'll notice how pressure and angle change the feedback.

Experiment with speed and depth to discover what intensifies sensation for you. Some users find that varying angle—tilting slightly as you stroke—engages different internal ridges. Temperature play (warming or cooling the device beforehand) adds another dimension. Explore the full range of Male Strokers if you want to compare grip styles, but this model's anatomical design rewards patience and attention to subtle textural shifts.

Always use water-based lubricant, rinse thoroughly after each use, allow complete air-drying before storage, and never share the device with partners without proper cleaning and consent. Safety first. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Discontinue use immediately if you experience pain, numbness, discolouration, irritation or discomfort, and seek advice from a qualified medical professional if you have a relevant health condition or if symptoms persist.

Care and storage

Rinse the interior and exterior thoroughly with warm water after each use. Use a dedicated sex toy cleaner if desired, then air-dry completely—moisture trapped inside promotes bacteria growth. Store in a cool, dry place away from direct sunlight and heat sources. Apply renewal powder periodically to keep the outer material soft and supple. Keep away from sharp objects and extreme temperatures.

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 →

This masturbator has become essential in my control work. The anatomical design means a submissive cannot simply rush through sensation—they must feel each layer, each shift in texture, learning to pace themselves under my command. I watch their breathing change as internal structures engage, and that tells me exactly how much control they've developed.

When I direct a submissive to use this device, the unpredictable feedback keeps them mentally present. They cannot zone out or rely on muscle memory. Instead, they remain acutely aware of every stroke, every pressure point. My dominance extends through their own sensation—I determine when they may begin, how fast they may move, when they must slow. The device becomes my proxy.

What impresses me most is how the skeletal core creates genuine surprise. Even experienced submissives report that they cannot predict which angle will trigger intensity. That vulnerability, that inability to anticipate their own pleasure, deepens submission beautifully. Power exchange becomes tangible when sensation itself resists predictability.
