NPG Shin Mature Star Aika Yamagishi Onahole

This is a dual-hole realistic sleeve masturbator designed with a two-channel internal structure that simulates both vaginal and anal anatomy in a single handheld device. Built with dual-layer TPE construction, the outer layer provides a soft tactile grip while the inner tunnel focuses on internal friction variation for stimulation diversity.

The product features a closed-ended design with two separate internal tunnels, allowing alternating use between two distinct internal textures. Each channel is engineered with layered ridges and tightening structures to create varied resistance and pressure during use.

Designed for solo use, this product focuses on immersive stimulation with a realistic internal grip pattern and high material flexibility. The structure is compact, weighted, and reusable, making it suitable for repeated personal use with proper cleaning and maintenance.

Use Case

• Solo intimate stimulation use
• Exploration of dual-sensation internal textures
• Users seeking varied internal friction experiences
• Private use at home with discreet handling
• Suitable for slow rhythmic use or faster intensity sessions

*Packaging may vary between NPG and JNPG branding due to manufacturer packaging updates. Both are official versions of the same product with identical quality, structure, and experience.
