Starting off smaller than the average go-to anal starter (the pinky finger), Booty Call's Booty Trainer Kit helps ease newcomers into the pleasures of anal penetration.Super sleek at the tip, each of the three curvy plugs gently widens the anal opening to admit a length gradually widening to a manageable stretch. The thickest midpoint swells out into a curvaceous bulb before tapering back down into a comfortably slender neck. A circular base protects agasint too-deep penetration- it also features suction for hands-free possibilities.In hypoallergenic pure silicone, the Booty Trainer Kit plugs are extremely hygienic and safe for sensitive skin. Clean-up is quick and easy using warm soapy water or a good toy care fluid/foam. For more thorough sterilization, run through the dishwasher (top rack, no soap), or wipe down with a 10% bleach solution. Compatible with any favorite water-based lubricant. Avoid silicone lubes and contact with other silicone products.* Measurements below represent the smallest plug.
