Yesterday my step sister was making fun of me, so i was poking her sides on the steps when she fell, so I sat on her legs and held one arm up above her head and tickled her underarm for about 10 minutes, she was screaming and laughing hysterically, she is sooooo very ticklish if she even sees someone tickling someone else she laughs and squirms. Anyway later on she told her fiance what i had done to her and he looked at me and said next time i tickle her he better be there to help me, and we both just smiled at her.
