G-project Goku-Tsubu Virgin

G Project Goku-Tsubu Virgin is a Japanese onahole with a closed-end tunnel and a detailed internal texture. Made from a single uniform material, it provides a consistent feel from the outer body through the tunnel walls.

The closed-end construction creates an enclosed sensation with added suction during use, while the internal design delivers changing texture throughout the tunnel. Explore the product photos for a closer look at the exterior shape and internal structure of G Project Goku-Tsubu Virgin.
