The inner cup of the Vorze A10 Piston SA sex machine is exchangeable, so you can conveniently switch cups when you're in the mood for something different. Developed to perfectly simulate deep-throat fellatio, the Vorze A10 Piston SA Beta Sleeve Throat inner cup mimics the exceptional oral technique of "throat tightening." The tongue part in the front performs a caressing, flickering action in response to the piston movement. As you move further back, the space enlarges and the pressure points are perfectly adjusted to stimulate your dick all around until you orgasm.
