Keep the beast caged in this vibrating penis sleeve, perfect for full shaft constriction and restricted play. The buzzing bullet on top offers multiple patterns and speeds of vibration for tantalising you during solo play or stimulating a partner. Slip the ribbed sleeve down the length of your shaft, then activate the bullet to start the vibrations. The sleeve expands from 1. 25 – 3 inches in diameter to fit most men, although we would advise coating the sleeve in lots of water-based lube before popping it on for the easiest fit.
