Licking?

Try practicing the perfect licking with an ice cream. Buy an ice cream cone, let it drip and as it drips down, lick it upwards. When you can perfect it you are now ready to lick your girl. Licking the nape, neck and back part of the ears would tickle her. There are also other parts of the girl that would make her "oh", finding those parts would be a nice try until you spot them. You can spot them by her reactions when you lick her all over. Good Luck!
