I found some older cheaper games, and our new favorite was Sim City for the computer.Not a board game, but we took turns with the other giving out ide...s for how to beat the scenarios.I was seventeen, and she was a fast maturing fourteen. She was told to wear more clothes around me, but she didn't ask why. I knew why.I was getting into schoolwork more, occasionally bowing out of our evenings pursuits, Trivial and otherwise. I had started reacting physically to my sister, getting boners. " But what?" You can fuck for it," I replied with a leering smile. Guadalupe paled and stared down at the floor. I'm sure she wanted to run away. I was old enough to be her grandfather and I'm not what you'd call handsome with thinning gray hair and a paunch that won't go away no matter how much I diet and exercise so I don't think I was her ideal lover. At least I still have my own teeth. She remained silent. I knew we couldn't do anything once her daughter woke up from her nap and I wanted to. She didn't want my penis out of her.“I need to pull out, Alyssa and I need to pull out now!”She only shook her head. As hard as I tried to push back against her legs, the more I tried, the more I failed. After one last attempt, I reached the point of no return. My testicles constricted, I felt my penis swell inside of her. Then my seed was released into her.All I could think about was my little Ernie’s meeting up with her eggs. This couldn't be happening. My penis continued to empty my seed. She would grab his balls and stroke them as she sucked hard on the huge cock. "Now cum for me. Fill my mouth with your cum and let me taste you" she yelled at him. He then did just that and filled her with a heap of his warm cum. "Oh I knew you would be able to cum hard with lots of cum for me. Now I want you to get hard again and fuck my cunt hard." She sucked and played with his cock and it took just a moment till he was hard again."Now fuck me hard and fill my cunt with your cum or I will.
