Grant these little beads access to your bottom and they'll repay you with a glorious intensity of sensation, as you grow to accommodate the super-smooth silicone spheres. Totally satisfy your sensitive nerve endings by working up to all four beads.

On the way in these bad boys feel rather wonderful, but just wait till you whip them out. Evenly sized for ease of use and with well-defined 'waists' between each bead, while the beads won't stretch you too wide. 

Slather your beads in water-based anal sex lube before use to enable slick sensations in play.
