How naughty do you want it? Made of high-quality silicone, the Mood Naughty 1 Trainer Set includes our best-selling Mood Naughty Butt Plug in three graduated sizes. At 3, 4 and 5 inches, this set is perfectly shaped and sized to help backdoor beginners gently push the limits of their anal experience. Mood Naughty's classic tapered tip slides right in, and the firm but flexible material and curved rocker base make these plugs comfortable and secure for extended wear.
