The "48 style" is the Japanese sex position manual and one of the position is called "Takarabune" (Treasure Boat). Called Treasure Boat because the female sits on the male body and holds one of his leg up like the mast of the boat. This is position that WAZ is designed after. Made with 3D interior structure and stretchy material, Takarabune is a great start to their series.
