We did n't really take any notice as we were engrossed in ourselves and the film . Shortly afterwards another came to sit down in the row in front , directly in the front of the other guy whose view of the screen was now slightly blocked , so when he moved to the seat next to Sandy , we did n't take much notice . After a few minutes Sandy whispered in my ear that the guy next to her was stroking the outside of her leg . I looked across and could make out his hand at his side , gently moving against Sandy 's leg .

What happened before the pervert started stroking the girl 's leg ?
