This suction device allows for the creation of pressure to enhance sensitivity around the lips and the entrance of the vagina. This can be a particularly erotic experience. This accessory is made from high-quality, clear acrylic material. The cylinder has a shape that tapers at the top to fit the natural curve of female anatomy. Each cylinder contains a modern air valve that allows for quick and easy disconnection from the pump while maintaining pressure inside the cylinder. No seals are required.
