While most of the other inner cups that fit in the Vorze A10 Piston SA sex machine have strategically placed bumps and ridges to enhance stimulation, the Vorze A10 Piston SA Alpha Sleeve Plain is completely smooth inside. The slick inner wall provides one of the best feelings of adherence among the cups in this series, and you can enjoy the awesome sensation of your cock being squeezed across its entire surface. The lack of any obvious stimulation is perfect for enjoying an experience where you are gently stimulated in a virtual space while linked up to your favorite VR porn. In addition, the overall tightness has also been improved, so an orgasm is never far off.
