When I got home from school today, I said hi to my step-grandmother who was in the living room smoking a cigarette. Nana, as I call her is a big woman with a huge ass and big tits. I’ve been fascinated with her tits since I entered puberty. After talking with her a bit my cock was stirring just thinking about them, so I decided to go downstairs and rub one out. I took my clothes off and started masturbating when suddenly Nana opened my bedroom door and of course she caught me jacking off. I thought she was going to scold me, but she didn’t. Instead Nana came over to my bed and sat beside me. Her hand immediately reached for my cock and she started to suck me. This is a fantasy of mine that was happening. After awhile of her mouth sucking cock I asked Nana to take off her clothes and when she did her huge breasts that I had always wanted to see spilled out right in front of me. They were saggy and freckled with nice perky pink nipples. Nana got back onto the bed with that huge ass right in my face. She started smoking on of her Virginia Slims cigarettes while my stiff cock entered her pussy which was hairless and wet with anticipation. I put my hands on her wide hips and began to push deeper into her pussy and each stroke was giving her pleasure. Nana began to talk dirty to me and it only increased how deep and harder I pounded into her. I didn’t want this to end too early so I pulled out of Nana, I turned her onto her back and thought that I would try something else I fantasized about. I wanted to fuck my Nana’s feet. She was more than willing so I started to fuck the soles of Nana’s feet. Oh my god they were so soft, and Nana knew just what to do with them. Nana got on top of me, started up another cigarette, and smoked while riding me in a cowgirl position. Nana’s big freckled tits were hanging over me and of course my hands were squeezing them while my thumbs and fore fingers were kneading her nipples. The next thing we tried was a little finger banging. I oiled up her fat ass and had perfect access to her oily cunt. I have long fingers and was easily able to reach her G spot while my thumb worked on her clit. My Nana was again moaning like a whore in church. I oiled up Nana’s big tits and placed my cock between them. I stroked between her big oily boobs and almost shot my load when her tongue snaked out and licked the head of my cock. This gave me the idea of where I wanted to cum with Nana for the first time. I sat at the edge of the bed and let my Nana suck me again. But this time I didn’t hold back I told Nana that I was about to cum but she didn’t stop she kept on sucking my cock taking all of me into her mouth and down her throat. There was one little drop that escaped, and she played with it in front of me.
