A fantastic anal pleasure kit along the same great lines as the rest of the unique Aneros toys, the Peridise set is a collection of 4 irresistibly shaped little probes meant to thrill connoisseurs of backdoor play. The Peridise set is completely unisex, each little probe was specifically designed to enhance sensation, increase blood circulation, encourage the flow of endorphins, and bring on what is known as peristaltic waves. If you've never experienced this sensation, it's though to be a product of rectal pressure and contraction that, through practice, becomes involuntary, stimulating the ultra sensitive, nerve packed anal canal and conjuring up some of the most intense orgasms imaginable. With 4 widths to choose from (.86inches(22mm), .78inches(20mm), .71inches(18mm) and .63inches(16mm), making the set ideal for both beginners and experts, each curvy, slim penetrator is shaped into thoughtful curves and balls which have been placed perfectly to stimulate at various depths and and positions in the anal canal. The idea is to start off with the larger sizes and work your way down to the smallest. As you become accustomed to the type of muscle contractions and movements that get the Peridise working, you'll find that the smaller versions will pleasure you even more. Each piece is made from safe, phthalate free FDA approved plastic with a nice smooth finish, making them not only very hygienic, but also quite economical in terms of lube, a little will go a very long way. You'll be able to use any type of lubricant you wish, but it's important to use a good quality product since the anal canal is not self lubricating. For easy, discreet storage, this set comes in a sturdy case with tips and advice on use included.
