I pulled out further, leaving the tip of my cock just barely in her entrance. Diana tensed, waiting for me to come back. I gripped her hips hard and s...ammed into her, driving my cock home, displacing all the liquid in one quick swoosh. Diana gasped, "Ooooohhhh, OMG!" I felt her body jolt with the force of my thrust. I drove into her harder and deeper with each thrust, she responded moving with me, driving her hips up and forward to meet my thrusts. Slamming the full length of my long thick cock. .. Since what? Why can't I remember? Did someone hurt me? Maybe the man who keeps bringing me flowers everyday hurt me? But she pushes that thought away, back into the paranoid place where it came from. He's never hurt me, never would, she silently assures herself. She remembers places and things with him. For three weeks she'd listened to him talk to her, bring her flowers, just sitting with her holding her hand never understanding who he was or how he knew her or her him.The words she heard. My step-grandmother was a very classy lady, quite pretty and trim, who had been a judge's wife until he died of a heart attack about three years before my mother married her son.My grandmother took to me and I took to her, we just clicked, if you know what I mean. So, I spent a lot of time at her house, often overnight, sometimes with cousins, sometimes by myself.Her house would probably be called a mansion, it was large, three stories with many bedrooms. I always enjoyed staying overnight. I explored inside her mouth and she took everything inside. She was shocked but loved the experience. Then, I moved my hands on her pussy over her clothes, it was wet. I moved my hands inside her and put my figure inside her, she started to moan.She was just enjoying all the experience and then she had her orgasm with a loud moan. She caught her breath and explained that in her whole life she never experienced such pleasure as she had only done little stuff. I winked and said there is a lot.
