This wonderfully unique pleasure tool can be used in all styles of male or female medical fetish play, anal sex training, anal stretching, male chastity / female chastity slave training and interesting anal experimentation. The stainless steel spreader arms should be well lubed before sliding them inside the anus. You, then, slowly open the tool, spreading and opening the hole for both stimulation and viewing. The sensation of the metal arms spreading you open is almost indescribable. It is a highly erotic experience and visually arousing, too.
