I was standing in the shower trying to process all of this when the shower door opened. My s****r was standing there. She slowly got undressed, and st...pped into the shower with me. She stood in front of me, completely naked, the water running down both of our bodies. My cock stood at attention. She reached for a bottle of shampoo and let it run all over her tits. She rubbed it in and her tits were shiny and smooth. She then got on her knees in front of me, grabbed my cock, and slipped it in. I held her tight against my body as John continued to assault her pussy and I violently squeezed and pulled her clit. She started kicking her legs and trying to squirm away so I rearranged my hand so I could also clamp her nose shut. Her hands flew to grasp my wrist but before she could pull it away and regain the ability to breath, I whispered to her, "Trust me Dirty Little Girl. I won't hurt you. Let go of my wrist if you trust me." Her hands slowly withdrew from my wrist although she was. “Here, you look like you need another,” she said, handing Sara an uncapped drink. “Come, sit by me.” A few guys scooted over on a bench to accommodate the two of them.Prior to the beginning of the summer, she and Ben had both been fortunate enough to land temporary placements. In each instance, they were much-needed boosts to their respective career paths. His was in the city where they already lived but hers was timezones away. Sara knew that it would mean a few months spent apart but she had. I loved riding the train. It was inexpensive, not nearly as bad as driving to work and fighting traffic and the wear and what have you on your nerves, the car, and all that.I also discovered a few things about the people who took the train. I also discovered the best way to flash people on the train.I had to drive to work on weekends, but, I got up every Monday and Tuesday, my days off, just to ride the train around to town and take a couple of subways. One day, I came twice, flashing.
