Here's a little vibe that so compact and discreet, you can sneak it anywhere. And, it's waterproof, so you can tuck it away and slip it into the hot tub for totally undetected sexual pleasure. The three interchangeable heads feature different textures depending on where you'd like to get your erotic massage and what type of stimulation you desire. The WaterPro is perfect for travel or anytime you need an orgasm on the go! Requires one AA size battery, not included.
