He got behind me and quickly undid my hands and bent me forward to the hood of the Honda. I stood, hands on the hood, as he pulled my jeans down and t...ld me to take my sweater off. He then unhooked my bra so I was butt naked there facing away from him and staring at my reflection in the car window. Fuck what a slut I am but I loved it. He guided me up on the hood so that I was on all fours, thighs opened indecently to him. He stroked my thighs as he kissed and nipped my big, white, mommy ass,. "Yes, you can. We both have to, and we will. And now I have to get back to work."We said goodbye. I very nearly uttered those three words, but I caught myself. Afterwards, I wondered why.There was a Wal-Mart in the major town up the highway that was more than sufficiently anonymous for my purposes. Three dozen condoms fit right in with shampoo, tampons, soap, deodorant, bubble bath, bodywash, and various male and female necessities. I didn't limit my purchases to the health and beauty. I don't know what made me stop and open my eyes, maybe just that feeling you get when you know your being watched. And there she was, standing in the doorway, staring at my throbbing cock.Suprisingly, she wasn't too shocked. "Can I watch?" she asked, sitting down on my desk chair. I was a little embarassed and hesitant. There I was laying with a raging hardon on my right hand and my older sister sitting there staring at it.I nodded.With nothing else to think of, I just grabbed it and started. Her boobs were big and her pussy was thick and partially shaved like any mature woman. She was enjoying a lot hugging him like her boyfriend.While hugging her, every time his cock touched her pussy lips. My cock also got extremely hard. They kept kissing each other. He was fondling her boobs and sucking her nipples.Ohh gosh! She looked so sexy. I was jealous of Zakir.He licked her navel and gave her oral pleasure by licking her pussy in a standing position. Her juices were flowing out of her.
