This purple-hued dildo covered with pliant latex is indeed slim and really does squirm all over the place once it gets going. A separate mini-rabbit, or clit stimulator, plugs in to the power pack. Three buttons control the functions. R turns on the shaft vibration and rotation. F varies the function - you can make the shaft rotate one way, then the other, then a bit of both at once. The V button controls the clitoral vibe. Each function goes at speeds from 1 to 6 - when you hit 7 they all shut off. Clever toy!
