It was summer, and school was out. My sister Joanne or Jo as I called her was getting ready for College in the Fall and working at Hal's burger palace...for the summer. I attended summer school to pick up a couple of art courses and to stay busy.I was home when Jo came in from the burger palace, and she smelled like hamburgers. Our parents were out for a day of golf and Dinner at the Country Club. I was in the den drawing and thinking about pizza or Chinese food for dinner. She came and watched. My god I had never notice the body on her till this moment. Her breast perked up, her legs, thighs and ass where so dam thick. She had an amazing body that left stuck in the thought of her, that for a second I forgot that she was my girlfriends mom.i was lost in thought I hadn't notice she began talking to me. " hey you ok? " she said. I snapped out of it and said " yea I'm sorry, what was the question"She asked if I knew what time her daughter would be home, " yea, about 4:00 maybe 3:50 " I. "Anyway, I told her she had a choice--to suffer all that in front of everyone, or to live with me for six months and be my slave. No beatings, no pain, just servitude. She had to do everything I say until three months was up. Everything. She has to cook, clean, and take my messages. And when I get horny and need to get off, I use her. However I want. She lives in my walk-in closet. There's a small mattress there for her to sleep. Sometimes, of course," Cobra said, stroking Sasha's hair, "she is. Fuck me, fuck me, hard baby.”I thrust my dickhead into her pussy. It slid in one smooth push as her pussy was so wet and not so tight. I started to fuck her wet pussy. I fucked her harder, deeper and faster. I put my left hand around her neck for support and started to fuck her faster.I spanked her ass harder. She loved it. I moved to my left and fucked her faster in an angle. I bent forward and kissed on her back neck. I slapped her hanging boobs. After few strokes of fucking her, I pulled out.
