Designed by world-renowned sex educator, author, porn director, and anal sex aficionado Tristan Taormino, this stay-put silicone plug features a contoured base that rests more comfortably between the butt cheeks. Tristan 2 is the second signature butt plug collaboration, inspired by fans who said they liked the original Tristan plug, but wanted one that was bigger, longer, and thicker. It also vibrates! Insert the bullet vibrator into the hollow core to add delightful vibration to your plug. Packaged in a beautiful, crystal clear storage box. 3 3/4" long, 2 1/16" in diameter.
