When the new guy finished he kept is cock out and started wanking as he watched us. It was nowhere near as big as a Mark’s, but still a nice size. A...ter a minute I reached over and started sucking this new cock. “Holy shit,” he said again. When he was super hard I stopped sucking and stood up. “I have to pee,” I said and hiked up my skirt, lifted my leg and put my foot on one side of the urinal, and pulled my panties to one side. The two men were stroking their cocks as they watched me start to. 'Why have you stopped?''I was stroking myself because no one else was here to do it for me. Now I have a beautiful young woman with me whom I hope will continue for me.' My own words caused a further realisation to hit me. Now in my eyes suddenly Jenny was no longer a girl, she was the beautiful young woman I'd called her. I desired her and my aching for her hit me hard. I'd done what I had just said was wrong. I'd involved one of the girls. However I had to take the chance. The potential prize. We were sitting together on the half empty train toward the front end of the carriage hidden from view from the other passengers who were all sat in seats behind us. A little way into the journey an older guy came through the adjoining doors from the carriage in front and passed by our seats into the carriage behind us leering at Mrs O as he went. I looked at her and she burst out laughing saying what a dirty old bastard he was when much to our surprise he came back and sat down a few seats in. Fearing that he knew what he would see, Dan looked down. His sleeveless T-shirt had become a bikini top, and contained two impressive breasts. Below the strange swellings were a perfectly flat stomach, and a tiny bikini clad mound. The mound had the hint of a vertical division contained within it. The legs that ran down from there were long, slender, and well toned, ending in tiny feet. Dan felt the world spin around him. He thought he had suffered a stroke or some other failure of his.
