I posted about this before. Years ago back in 2002ish my then girlfriend Kate. I knew she was really ticklish on her sides from her girlfriend a telling me and b having started tickling Kate for myself lol. Me, Kate, her girlfriend and the boyfriend of the girlfriend went to the cinema to see the Matrix Reloaded, yes that is how long ago it was!
I digress anyway, I can't remember if I already knew about this or not, or I just discovered it there and then. But Kate as usual was being tickled by her girlfriend and was squirming and quietly giggling, I was annoyed because I wanted to hold my girlfriend. 😀
Anyway........ the film started and between me and my girlfiend, we tickled her sides causing her to silently laugh and squirm. I remember putting my hand in her pocket and tickling her there, she started squirming around, it was definately really ticklish for her! I remember also saying to her girlfriend, hey watch this and then we both tickled Kate's pockets for a few minutes. 😀
