My favorite story about "pockets" came before I knew they were called "pockets".
I was in college and I was slowly turning my then gf into a tickler/ticklee.
We were laying around and a knock came on the door and a male friend walked in with a mutual female friend draped around him. SHE was a tickler. No doubt about it. Still is. She was haing on to his upper-body and trying to illicit even a smile by tickling his sides and ribs.
He asked, very calmly "Can you do something about this"?
So I got up and reached down and tickled her "pockets". She screeched and let go of him and he walked away.
As she chased after him I heard her asking "How did he know about that??!!"
This all happened in front of my gf. As it was she had to leave soon after and she asked where I had tickled her...so, mid sentence I tickled her in the same spots!
She got wide-eyed, laughed out loud and stood there staring at me. I said "Oh! I found your off button!" because she had stopped talking. She said "It ain't an 'off' button!" And kissed me.
Throughout our dating we tickled each other a lot, obviously, but the best/worst time she got me was the "pockets" too. I was laying in her bed she got in like she was going to crawl across me to the other side of the bed but instead straddled me, facing my feet, and dug into MY "pockets". I went nuts and almost threw her off the bed to the floor (involuntarily)! LMAO!
Good times...good memories.
