Just came across this while surfing some websites. Not sure a kiwi fruit would last long enough for me to cum.
"All you need for this technique is one kiwi fruit. Cut it in half and eat most of the inside, but leave about 4 millimeters (about a quarter inch) of fruit on the inside of the skin. Then cut off the top and bottom of each half (depending on your size), use it to line a ring that you make with your index finger and thumb, and masturbate."
