My step-grandmother was downstairs in the guest bathroom when I heard her call for me. She asked me to apply some lotion to areas that she couldn't reach. I don't know where the courage came from but my hand dove for her breast and I heard a little moan escape her lips. With both hands full of her big tits, I suggested to her that we go to her room. She sat on the bed and started to suck my rock-hard cock. I pushed her back on the bed and my cock into her. Surprisingly she had about the tightest pussy I'd ever been inside of. We fucked in every position I could think of and when I fucked her doggie style, she lit up one of her long VS 120cigarettes and I fucked her while she smoked. I pounded her cunt until I just couldn't hold off any longer. She got on her knees, and I busted a huge nut into her mouth.
