Finally, four days later, the blood showed up, and we could all relax.Sarah was dancing around in the grip of complete frustration as she had to wait ...ne week after her flow started to be sure that she was not having any difficulties. Her sisters enforced this, not me, but we were all concerned for Sarah's welfare; in fact, much more than she was. She kept insisting that she "was ready to fuck!"Finally, it was time! Sarah even took a bath, although it was not Saturday. Her sisters insisted that. I guess I am just a little out of shape for riding."I saw that indeed, the entire crotch of her jeans were a darker shade of blue than the legs were. I am such a gentleman, told myself, I am not going to say a word about that girl's wet pants.When she said she was ready, I took off running again, and she stayed close behind. It was exhilarating to be sure, and the wind blowing through her hair and the excitement of the ride made her all the more beautiful to me. I decided we needed to stop. She looked at me with a wry smile on her face, and an invitation in her eyes."I'm Tom," I said."Sue," she replied, with a wink. We both knew what was going to happen. After finishing our meal, I led her to the sleeper car and found my berth. I opened the door and let her enter. She stepped through without hesitation. I followed, closing the door behind me. Once we were alone, my arms wrapped around her waist. I kissed her neck, and she tilted her head exposing more of it. My hands rested on her.
