Suction provides exquisite sensation and enhanced sensitivity! Three small cylinders connect to a compatible pumping device to pinpoint pleasure on nipples, the clitoris, and other small areas. Create a strong seal, with the aid of a lubricant if necessary, and experience the tight pulling sensation as your delicate flesh is drawn into the cylinder and blood flow increases. The convenient clasps allow each accessory to be disconnected from your pump while still retaining the pressure within, allowing the use of all three cylinders at once. Release your tender parts for access to more hands-on play by pressing the small silver button on the top of each clasp. These small, durable pumping accessories are a stimulating way to amplify your solo or partner play! Measurements: 3.8 inches in total length, 2.9 inches insertable. 1.1 inches in diameter at opening, .85 inches in diameter throughout length of cylinder. Material: Plastic. Color: Clear. Note: Pump not included.
