These advantages features combine with an arousing "slurping" sound and vibration to give you the feeling that you're enjoying a real deep throat experience. Instruction Peel the packaging film off the cap part along the perforations. Watch your fingers while peeling off. Tear the silver seal off the cup head before use and open the air hole. Pressing and releasing the air hole when using creates differences in sensation. Remove the bottom cap and slowly insert your penis direct through the hole in the bottom of the cup. Gain pleasant and most excited feeling just like the real thing. Move it back and forth as you like. After use, put the bottom cap properly back on the TENGA onanism cup, and please dispose of it with regular trash according to the waste treatment regulation of your local residential area.
