A simple trio of suctioning clit and nipple erectors from XR Brands' Size Matters collection, the Sucker Set includes three extremely user-friendly, ABS plastic suckers for enhanced sensitivity of erogenous zones body-wide. Each four inch long tube is fit with a twist dial to create incredible suction when turned clockwise, enlarging the nipples and clit for heightened sensation and easier stimulation. Once you've reached your desired level of suction, these suckers will stay absolutely in place considering their maximum suction capabilities, only loosening when the dial is twisted counter-clockwise.
