I remember when i was like 15 i had this friend who loved to be tickled, she wouldnt admit it at first though, but she would find ways for me to tickle her. One day i was at her house and we played the "tie up game", i went first. She didnt really tickle me that much, just a couple pokes here and there. Then it was her turn and she wouldnt let me tie her up, so i said fine, i'll only tie up your feet, and she agreed. Once i had her feet tied up to the foot board of her bed she couldnt reach me with her hands. Then i said i had to put something in her mouth (even though im not into that) so i took her socks off to put in her mouth, but i never put them in there. Then i sat down on the floor in front of the foot board and started tickling her feet. She tried to hit me and wiggle out, but she couldnt. This went on for a good 5 minutes, then i sat on top of her and pinned her arms down with my feet, then i started tickling her upper body. Then i got to a spot that wasnt ticklish and she said in a taunting voice, it doesnt tickle. Then i figured it out, she liked it! Then i asked her if she did. She said a little. Ever since then i had been tieing her up and tickling her all over for hours. Then i moved when i was 19 and havent spoke to her since. I still have her number though, so i think im gonna call her up.
