The Onyx butt vibrator is designed for its weighted "filled up" feeling. It's name means black gemstone, which has inspired the multiple, gem-like edges, which provide a sensational feeling of fullness for the wearer. Its silky soft silicone and heavy stature will allow for uniquely pleasurable use. The powerfully low-frequency rumbling vibrations will penetrate your pleasure spots from deep within. Perfectly smooth silicone, a contoured shape, and a slim neck make backdoor exploration oh-so-comfortable, while the flared base keeps things safe and sexy. Add your favorite water-based lube, and let the fun begin. Silky-smooth, body-safe silicone for a sensuous feel. Contoured with a rounded tip and slim neck for easy, pleasurable play. Wide base for safety and peace of mind. 5 speeds + 7 vibration patterns to keep you guessing (and gasping). Remote controlled for hands-free fun. USB-rechargeable for up to 90 minutes of uninterrupted bliss. Whether you're indulging solo or sharing the buzz, this plug knows how to bring the fireworks.
