A deep sucking sensation is made possible by the special internal structure. Special valves create a virtual vacuum inside the cup, delivering an amazing sucking sensation. The unique pinched-in shape of the 6 inch long masturbator helps to achieve an unparalleled tightness. These advanced features combine with an arousing slurping sound and feel to give you the feeling that you're enjoying a real deep throat experience. Designed for single use, but re-use is recommended with condoms.
