This is a powered closed-type masturbator inspired by Japanese adult video performer Konan Koyoi. It is a dual-layered internal sleeve device designed to simulate realistic internal structure, combined with an electric system that provides suction and vibration functions for enhanced stimulation. The product is classified as a battery-powered automatic masturbator with a non-penetrating external casing and an internally structured stimulation canal.

Core Function

The device integrates two motorized systems: vibration and air-based suction. Users can control both functions through built-in buttons, enabling adjustable stimulation intensity and rhythm. The internal sleeve features a multi-zone textured canal designed to create layered pressure, grip variation, and directional stimulation along the shaft during use.

When and how it is used

This product is intended for solo private use. It is suitable for users exploring enhanced stimulation experiences beyond manual masturbators. It can be used in relaxed home environments where privacy is ensured. The powered suction and vibration functions make it suitable for extended sessions focused on varied intensity control and sensory exploration.

Who it is for

This product is designed for:

• Beginners who want a guided automatic stimulation experience
• Experienced users looking for stronger mechanical stimulation systems
• Privacy-focused users who prefer closed-type, discreet devices
• Users who prefer hands-free or low-effort operation sessions

Experience Layer

The internal structure creates alternating tight and soft pressure zones, offering a layered tactile sensation. Vibration adds rhythmic external stimulation while suction introduces a pulsing internal pull effect. The overall experience is controlled, adjustable, and progressively intense depending on selected mode combinations. The device is designed to feel immersive, consistent, and mechanically responsive.

• Best For: Users seeking automatic suction and vibration combined stimulation in a structured internal sleeve design
• Use Case: Solo use with adjustable intensity stimulation sessions
• Experience Type: Mechanical rhythmic stimulation with suction and vibration layering
• Recommended Scenario: Private at-home use during relaxation or personal exploration sessions
