G-spot stimulator. 4'' long. This massager is an anal sphincter-driven, prostate-perineum massager, with which men can achieve strong continuous, non-ejaculatory, full body orgasms previously unattainable through conventional sexual techniques. We refer to this type of orgasm as the "Dream Orgasm," while many of our users call it the "Super-O." What makes this item truly unique is that it is a hands-free, self-propelled device. It converts the anal sphincter’s natural motions and contractions directly into stimulation of the prostate and perineum, meaning that the user does not use it have to use it manually. That's right, no hands! It works on its own whereas other available devices require some type of manual intervention, which either requires the help of a partner or the individual being limited to a number of positions that he can effective massage the prostate while manipulating it with his hands. This has no such limitations. Sitting, standing, bent over, upside down -- there are endless possibilities to the positions that it can be used in.
