After a while, his head started shaking in the rhythm of the train. His head was bobbing side to side. And soon started moving toward my inner thighs....Once in a while, his head would jerk and touch my limp dick in my jeans. I was alarmed but thought it was by accident as I was thinking he is asleep. He would go back to normal and pretend to be asleep with rhythmic movement to match that of the train and the people around. And I continued to ignore him. This continued for a while and his head. After a few moments she happened to look in his direction. That was when she realized that he was a male who was boldly growing his erection based on what he saw of her body. Erin was not pleased. But I imagined she was less pleased with me, since he was only doing what came natural. I saw it all in profile, she was surprised, displeased, and upset. But “turn the other cheek” Erin did not get dramatic, she just returned to her business. She turned her body slightly away from him to put a hip. He was not subtle, he used his huge fists like hammers, trying to hit my face and upper body. I kept moving backwards and blocking and dodging his swinging fists. I could smell alcohol on him and I could see his eyes were bloodshot in the light from the street light. One of his wild swings caught the top of my left arm and I could feel it go numb almost immediately, fortunately was he was tiring from his initial onslaught and he stopped, hands on knees, watching me move my shoulder. He was. .......N-n-nothing" She nervously stammers out and I see that her pants aren’t moving anymore."No seriously Sarah, You can tell me."She takes about 2 minutes to think about something the whole time contemplating whether or not to say anything, but apparently she decides that she might as well and says."Alright, I trust you enough," she blushes even more and nervously whispers” I was masturbating." I-I-I couldn’t help it, I’ve wanted too all night, I mean becca's sooo hot and I got to make out.
