After the point of him finding out how much I loved his cock he was more than happy to give me as much cum as I could swallow.I loved that sometimes h... would creep in while I was using the restroom and he would stand in front of the toilet while I sat there and sucked his cock dry. I hated the idea of not being able to swallow it or missing a drop.I used to stay up late, even when I was very tired, because I knew that as soon as grandma was deep asleep grandpa would come to my room for some. When we dated I constantly bought her sexy outfits to wear when we went out, like very short skirts , see through panties and sexy high heels. One of our first things we liked doing was shoe shopping while she wore a short skirt. She would accidentally show the salesman her pussy through her see through panties. She would see if she could get the poor guys cock hard enough to show through his dress slacks. As we walked to the next shoe store I'd tell her to show off even more. She once gave the. It wasn't intentional, but she was addicted to sex, her body craved it. Place her around a guy or guys, and somehow the situation always turned to sex. She was lucky that she hadn't caught anything, yet. As far a pregnancy, her mom had put her on birth control when she was twelve, no questions asked. None needed to be asked, as her mom was thirteen years her senior, and her grandmother just celebrated her 40th birthday earlier this year. Apparently a strong libido ran through the girls in her. So I sat there naked in front of my step sister eating pizza and drinking beer, and every once in awhile rubbing my hand on her leg, or one of her breasts, or on her beautiful stomach and hips. When I was done she stood me up and hugged me and grabbed my cock again, and told me to come with her. She lead me into the bedroom and asked me if I wanted to fuck her, or make love to her? I told her both, but mostly wanted to make love to her if I could only do one. She winked at me and said good.
