See yourself in a whole new way. The innovative Optix model enhances Doc Johnson's Main Squeeze line of masturbators with adjustable pressure and features a unique, completely transparent design that leaves nothing to the imagination. Every part of Optix, including the casing, adjustable pleasure features, and the snug, textured ULTRASKYN tunnel, is crystal clear, providing an unparalleled, visually stimulating experience. As always, Main Squeeze is designed to put the power in your hands, with a squeezable grip that allows you to vary the tightness of each thrust and a suction-regulating end cap. The dual hard-shell design also serves as a discreet travel and storage case, keeping Optix as sleek and pristine as the day you opened it.
