The Nexus O is a serious silicone innovator thanks to its unique three ball design which works to stimulate the G-Spot and perineum whilst providing a secure fit, leaving your hands free to wander wherever they please! Developed in conjunction with the UK Sex Worker of the Year, the Nexus O works by harnessing the natural movements of the body in order to massage and stimulate the three key areas and create a slow, powerful all over body orgasm. Ball width 30mm e or 1.18 inches, shaft width 20mm e or .787 inch.
