The ZOLO Long Stroke is a male masturbator designed to fully surround your shaft with warming and thrusting technology! The multi-ribbed sleeve with incredibly satisfying textures enhances pleasure, and the built-in optional sounds allow for discreet pleasure with a headphone jack. Automatic stroking means you donb t need to manually thrust. Five speeds and five vibration modes combine to make ten unique functions. The Long Stroke uses USB charging and is made from hypoallergenic materials.
