G PROJECT Kuu-Sou Ultrasoft Onahole by Exe and King

The G PROJECT Kuu-Sou Ultrasoft Onahole by Exe and King is a Japanese-engineered masturbator featuring dual-layer construction with an ultrasoft exterior and precisely textured internal chambers. It delivers customisable stimulation through innovative block-shaped design and closed-end suction effects. Men seeking comfort without sacrificing intensity find this stroker hits the balance they've been looking for.

What's in the box, and what it does

The G PROJECT Kuu-Sou Ultrasoft Onahole by Exe and King is built around a dual-layer system: an ultrasoft exterior that yields naturally to your grip, and a precisely engineered interior with multiple texture zones. The closed-end design creates improved suction as you stroke, building sensation from gentle initial contact to deeper intensity. Unlike basic strokers, the block shape opens multiple positioning options, so you control exactly how you experience each stroke. The internal chambers feature progressive texturing that works differently depending on your angle and pace.

Japanese engineering runs through every detail. The low-odour material means no artificial smell interfering with your experience, and the construction quality means the stroker maintains its performance across extended sessions. Unlike textured strokers that rely solely on surface bumps, this masturbator combines external softness with internal layering that creates a more comprehensive sensation profile.

Notable features

• Dual-layer ultrasoft compound: The exterior feels genuinely plush while the inner layer maintains precise structure, creating a balance between comfort and stimulation.
• Progressive texture zones: The design starts with gentler nubs at the entry and transitions to firmer folds deeper inside, building sensation as you stroke.
• Block-shaped design: Allows adjustable positioning so you can angle and manipulate it to target different sensations during use.
• Closed-end configuration: Creates improved suction effects that intensify with your stroking pace, delivering more satisfying results than open-ended alternatives.
• Included lotion sample: G PROJECT x PePe 5 ml sample gets you started immediately without needing to source lubricant separately.

The detail

• Dimensions: 175 mm length, 80 mm width and depth—compact enough for discreet storage, substantial enough to grip securely.
• Weight: 820 grams; the heft signals quality construction and stays put during use without rolling around.
• Material composition: Dual-layer ultrasoft compound throughout; non-porous, low-odour, and engineered for durability.
• Closure: Closed-end design; no opening at the base, which maintains suction intensity and simplifies cleaning.
• Box contents: Masturbator unit, 5 ml G PROJECT x PePe lotion sample, and instructions.
• Texture profile: Multiple internal zones with varying firmness; entry nubs progress to deeper structural folds.

Setting up a masturbators and stroker

Start by washing the stroker thoroughly under warm water with a toy cleaner or mild soap, then air-dry completely. Apply a generous amount of water-based lubricant to both the exterior and inside the opening—the closed-end design means lubrication stays inside and builds that satisfying suction. When you're ready, grip at a comfortable firmness and begin stroking at whatever pace feels natural. The block shape lets you experiment with angling it slightly to discover which internal textures hit best for you. Pay attention to how the suction builds as you continue; it's part of the design working as intended.

First sessions often reveal that the softness of the exterior contrasts beautifully with the internal intensity—many users find they prefer slower, deliberate strokes initially to feel how each texture zone responds. Unlike open ended strokers, the closed end means you can't simply rinse during use, so plan your session length accordingly. After finishing, empty any fluid, rinse thoroughly with warm water, and stand it upright to air-dry completely before storage in a cool, dry place.

Who should buy it

Care and storage

Rinse the stroker inside and out under warm running water immediately after use, then wash with a dedicated toy cleaner or mild soap, ensuring you reach inside all the texture zones. Pat dry with a soft cloth, then stand upright to air-dry completely—this step is essential because any moisture trapped inside can lead to degradation. Once fully dry, store in a cool, dark, dry place away from direct sunlight, ideally in a breathable pouch or box that allows air circulation. Keep away from extreme heat and do not store touching other toys or materials that could cause staining.

Background reading

Understanding how strokers work and what separates quality designs from basic ones helps you make a choice that lasts. Japanese-engineered masturbators have earned their reputation through attention to materials, internal architecture, and the balance between comfort and sensation.

What to expect

The ultrasoft exterior feels noticeably different from standard strokers the moment you hold it—the material yields to pressure naturally, which many first-time users find surprisingly luxurious. The closed-end design creates suction that builds as you stroke, meaning the sensation actually intensifies with pace rather than remaining static. This is a deliberate feature, not a flaw, and learning to control your rhythm helps you discover the stroker's full range.

First sessions often surprise users with how the internal textures vary; the progressive design from gentler entry zones to firmer folds deeper inside means no two strokes feel identical. The block shape takes a moment to figure out—you'll naturally find angles that feel best as you explore. Most people discover their preferred positioning within the first few sessions and return to it consistently.

Cleaning is straightforward because the closed-end means no water gets trapped in unexpected places, though you do need to ensure the interior dries completely. The material holds up exceptionally well; the ultrasoft compound doesn't degrade quickly if cared for properly, and users report months of consistent performance without any deterioration in sensation or structural integrity.

Men who struggle with strokers feeling too intense or too basic tend to keep this one because the ultrasoft exterior removes the harshness while the internal structure delivers genuine pleasure. Conversely, those seeking minimal texture or ultra-realistic designs sometimes find the block shape and internal zones too engineered-feeling, so the design isn't universal.
