I'm not sure how you got away with that one! In my experience, the odds are if the woman tried to kick your hand away, she would look down to see what she was kicking if it wasn't moving. Seeing a guy's hand under her seat in a movie theater would freak almost any woman out, so you should have definitely been busted. Guess you just got really lucky!
Your experience reminds me of a time when I was in a theater watching the Rocky Horror picture show - you know, where everyone dresses up and yells out different lines in response to the movie. As it turned out I was sitting in the back row next to a pretty asian brunnette in her early twenties who was sitting on the back of the theater seat to get a better view of the show, because many people were standing up. She was appropriately dressed in all in black with a tight blouse, a pair of "skorts," and chunky high-heeled black boots. Sitting on the back of the chair, her feet were on the seat itself, so...well i just couldn't resist sliding my hand on her seat. The situation couldn't be more perfect. It was so dark she couldn't see my hand (I could barely see it either!) and moreover, she couldn't even feel my hand as it would simply sink into the seat cushion as she stepped on it. The feeling was awsome! The stepped and stood on my hand for almost two hours straight. One would think that it wouldn't be that painful, but my hand was being bent akwardly by the springs of the seat cushion in addition to the crushing! The pain was more of a long-term type; believe me after two hours, my hand had no circulation, and felt like it had been bent back like Stretch Armstrong. I had extremely painful pins and needles for a half hour, and her tread marks lasted for a couple of days.
And all the while I was sitting right next to her and she never knew! We even cracked a few jokes with each other about the show while it was happening! I had a girlfriend at the time so I didn't try to get her number or anything. But it was definitely a memorable experience!
