First Time I Was Groped

I was in high school and had to stay late at school.I was the first time I took the subway at rush hour and was amazed at how crowded it was. I'm pretty tiny, 5'2", and was overwhelmed by the crowd but squeezed onto the train because I was anxious to get home. With people pressing in from all sides I didn't notice it first but quickly realized there was a hand fondling my bottom. Shocked, I froze for a minute trying to understand what was happening. I tried to wriggle away but it was too crowded. The hand kept gently squeezing, stroking. It didn't take long until the fingers were stroking my bare thigh under my skirt. Squeezing my thighs tight together I stayed still as the hand began stroking my panties. My head was spinning and I didn't know what to do as the stranger fondled me. When the train pulled into the next station some people got on, others got off and everyone sort of changed position and the hand was gone. I was still trembling when I got home and laid down on my bed, strangely horny. That made me feel ashamed but I *********** to the first real ****** I'd ever had. That made me feel even more ashamed but the ****** was so wonderful, so warm, that I often stayed late at school so I could ride the crowded train home. Still, whenever I'm lucky enough to be on a crowded train I hope to get groped and my hopes have come true many, many times...
