I remember one time I started tickling her sides while in bed and she started squirming. She tried to push my hands away so I decided to go down to her feet, putting them in an arm lock. I started scribbling my finger all over her soles and she went crazy. She was bucking up and down trying to get her feet away. She eventually got one foot free and and started kicking me while twisting and turning and she eventually threw me off the bed but I never let go or stopped tickling the foot I had control of. I distinctly remember her saying during her fits of laughter "oh my God! How are you still tickling?!" . She then went back into hysterics. I was so turned on I let her go, jumped back on the bed and we had sex right there.
She knew what tickling her did to me and she loved that she had that effect on me. She was ticklish literally everywhere, especially after a couple of drinks and I never passed up an opportunity to take advantage of that.
