Ready for a (pretty easy) riddle? Good, because here goes: what do you get when you position a jiggly, free-rolling weight into a classic tapered shape? The answer, hopefully not surprisingly, is SONO's No. 91 Self Motion Butt Plug! Designed for all kinds of butt-centered enjoyment, this sleek, sexy and super-textured silicone plug will jiggle and wiggle to anyone's, any body's, and any booty's delight.Super slim at the tip, the ultra flexible No. 91 penetrates comfortably before widening out to a gently stretching and stimulating midpoint. A nice long neck and big, sparkly circular base helps hold the plug in place while doubling as a safety feature – No. 91 won't slip too far inside.In hypoallergenic silicone, this butt play treat is a fantastic choice for pleasure seekers with sensitive skin. Clean well before and after using warm soapy water or a good toy care fluid/foam. Compatible with any favorite water-based lubricant- silicone lubes should be avoided, same goes for contact with other silicone toys/products.
