Fun For Everyone The perfect introduction to unisex anal play, Peridise continues the Aneros tradition of intelligent design. You’ve never experienced an anal toy like this before because there’s never been anything like it. By utilizing the body’s natural responses after insertion, The Peridise begins to quiver on its own, generating an orgasmic response that can stand alone or enhance a traditional orgasm. Nothing Like It The Peridise has two knobs which work with your body to trigger a repeating push/pull response. As rectum seeks to eject the Peridise, the knobs send it back in. This happens in very rapid succession, triggering a peristaltic response in the anal cavity, increasing blood flow and providing pleasurable anal sensations.
