Quite a few years ago a gal suckered me in....I was on my back with her sitting on my tummy and rubbling my chest. I didn't have tickling on the brain at all at the time...suddenly, she moved forward and pinned my upper arms with her knees and went to work under my arms. Its the only time I've ever been overpowered and I was super ticklish....didn't take long for me to start begging...and it was such a turn on!!
Awesome! Very cute and innocent. I'd totally want to try that. It might be hard for me though since I'm rather small compared to him.
