The slim Mystim Double Dan is suitable for anal and vaginal use and is designed for especially easy insertion thanks to its compact and straight shape. This - and the fact that the separation of the plus and minus poles is located only a few centimeters from the tip - makes Double Dan a perfect choice for electro stimulation beginners: the soft tingling, rhythmic pulsating or sensuous pushing sensations can be felt very soon after insertion.On deeper penetration into the vagina or anus, you can enjoy both the softly narrowing dildo and the continuously changing electrical stimulation. If you tense your muscles now, the stimulation immediately becomes more intense so that you can control, and increase, your sexual arousal without using your hands until it leads you to unbelievable orgasms.The dildo is made of medical aluminum and polished neatly by hand. It can be warmed on the heater or cooled in the refrigerator. The temperature is long lasting and creates another kick.
