The Spider Egg is a silicone egg that is ribbed for your pleasure. The design of the inside of the egg was influenced by a spider's web, starting out narrow at the top and then expanding as it goes down. The egg comes with its own package of lube that is already in the egg, you just have to unwrap it, open the package of lube, squirt it in and you're off. You'll love the way the side of the egg feels pressed against your member as it expands and stretches to fit you perfectly.
