A 'deep' sucking sensation 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 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 with condoms.
