My reveries and musings, half daydreaming of long ago were shattered by the cry of my companion, “Race ya!” And she was gone - hooves thundering, ...aising the dust from the dryish soil below the blades of grass. I laughed as I spurred my eager horse on, lying along its neck, half standing in my stirrups as we took off in pursuit. The few seconds she had gained by springing the surprise on me gave her twenty, maybe thirty yards head start, but my pony, a hand or so taller, was not going to be. She was smart and funny. She was also quiet and meek at times. When we start talking about the exs again, the hurt and fragility were clearly visible on her face. I just wanted to wrap her up in a big hug and never let go. As we talked by the light of the tv screen and sipped wine I started running my hand over her body. I came to her stomach and she quickly grabbed my hand.“What?” I asked. “Is something wrong?”She sighed and then pushed the covers back. She had stretch marks on her. She was shaking as she brought the boxes over and put them on the table. She was nearly in tears.“Oh Miss, he could see everything,” she said plaintively. “Don’t be such a baby, I’m sure he’s seen worse. I once made a girl open the door stark naked with the money sticking out of her pussy. I think they take turns for the chance to deliver here. You’ll be the talk of the local takeaways for a few days that’s all. Now open those boxes and let’s eat. I’m starving.”I chuckled to myself. From where. Babs was pissed that I came on her face. But Mom and I didn't care at all. Mom licked the come off her face and snowballed her. By now Babs was crying, Saying that we should stop this and she would quit making us her slave. Mom told her. "We aren't your slaves, but you are ours, now" Babs didn't know what to do. As Mom went down and ate her pussy to an orgasm. Only took about a minute and half. Babs was turned on. My cock was hard again and I proceeded to fuck my big sister as she lay there.
