There was an adult movie theatre in my college town, back in the late 1980s before all porn was internet porn. I checked it out and discovered that sometimes female coeds attended these movies, and that when they did, they always sat together in the very back row of the theatre. I came up with a great idea that didn't work every time, but when it did not work, there was not trouble because these girls did not want their parents to know they had been to a porno flick. Plus they had not "really" been molested, as you will understand when you read this.
What I did was pay off the manager of the theatre so I could close off the back row of seats. I filled the seats and space with packing boxes, as if they were going to replace the seats, but actually the boxes were empty and connected so I could move inside them and move along the center row which was 10 seats long. I bribed the ticket sales lady to phone me when a group of women paid for tickets and I lived close so I could get over there and get into the end box, which gave me access to the entire row, although it did not look like it to the casual observer.
That took some doing but I bribed the projectionist to bring up the lights and when they went down, before the screen lit up, nobody could see anything and I could jump across the aisle and enter the end box.
Then it was just a matter of moving along the box, and reaching under the seat in front with my arm. Now you might think this wouldn't work because there was no way to get my arm far enough under the seat to make the turn and reach back for pussy. But that is the beauty of my plan - although I do have long arms. I didn't go for the pussy. I caressed the ankle!!
