Vibrators.com loves the King Cock Double Penetrator because it combines three of our favorite things: high-quality realistic dildos, sensual vibrations, and dual stimulation. The Double Penetrator takes a standard King Cock Vibrator and makes it even better by adding on another realistic cock with its own vibrating motor for anal penetration and stimulation.King Cock Vibrators feature a firm core made of ABS Plastic surrounded by a deliciously textured and highly realistic sleeve made from phthalate-free PVC. The sleeve is not only modeled after real penises for hyper-real veins and head texture, it’s also very soft and flexible. The inner spine of the King Cock is also flexible and posable, so you can bend the vibrator to mimic the natural curve of a penis or hit your G-spot just right. The anal stimulator portion of the King Cock Double Penetrator is also fully flexible for optimal positioning.King Cock Vibrators also boast a wide range of deluxe features. They’re waterproof, strap-on harness compatible, and have a removable suction cup base that allows you to mount them to walls or other surfaces. They also have a dial near the base that allows you to easily control their incremental multi-speed vibrations. Made from phthalate-free PVC and ABS plastic, King Cock Vibrators are hypoallergenic and non-toxic.The King Cock Double Penetrator is 8 inches long in total. The main shaft has an insertable length of 5 inches and a diameter of 1.75 inches, while the anal stimulator has an insertable length of 6 inches and a diameter of 1.4 inches.The King Cock Double Penetrator takes 3 AAA batteries in the main portion and 2 AAA batteries in the anal stimulator (not included). King Cocks can be used with any water-based lubricant and should be cleaned with antibacterial sex toy cleaner or warm water and soap.Understanding Sound and VibrationHere at Vibrators.com, we test each and every vibrator for vibration and sound levels. Our Vibrator Institute doesn't test vibrators the way you might think; instead, we use scientific equipment that reads vibration and decibel levels. Based on these levels, each vibrator we sell gets a rating. The Power Level ratings are Gentle, Pleasurable, Intense and Unrelenting. The Sound Level ratings are Whisper, Purr, Hum, Buzz and Thundering. The King Cock Double Penetrator has a rating of Pleasurable Purr. This means it vibrates at average speeds, and have a fairly quiet sound level.If we don't like the look, feel, sound or vibration level of a sex toy, we don't sell it. That's why Vibrators.com only sells about 300 vibrators. There are tens of thousands of vibrators on the market, and that's a lot for a customer to wade through. We offer only the best vibrators, so you can choose the best vibrator for you in the easiest way possible.
