When I got home from college today, I said hi to my granny and then went to my bedroom. I started masturbating when Nana opened my bedroom door and caught me jacking off. 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 a while, she took off her clothes and her huge breasts spilled out. She lit up one of her cigarettes and started to smoke while I entered her pussy. She began to talk dirty to me. I turned her onto her back, and I started to fuck the soles of her feet. Nana got on top of me, lit up another cigarette, and smoked while riding me in a cowgirl position. The next thing we tried was a little finger-banging. I oiled up Nana’s big tits and placed my cock between them and then I sat at the edge of the bed and let my Nana suck me again. She took in all of my cum and there was one little drop that escaped and she played with it in front of me.
