She bounced up and down on me and I bounced up and down on the mattress. We quickly got into a rhythm where she was coming down as I was going up. Whe... she landed she was catapulted right back up into the air. It was like fucking her on a trampoline or on a waterbed, it was fantastic. She didn’t weight anything and it was no effort at all to keep it up. The sensation in my cock and balls told me that I couldn’t last much longer so I gave Judy a warning. She rode me like a bucking bronco and she. I began to fantasize it was your cock in me instead of your father’s. I came so hard ... so hard!”“Mom you must stop talking like that!”Mom’s hips pumped slowly as I trimmed the last straggly hair.“Tommy?”“Yes mom.”“I’m not ashamed anymore!”“I need to warm a towel,” I muttered as I stood.I realized I was seeing the effects of Cognitive Decline. Mom’s societal strictures were gone. Her most secret thoughts, the ones someone once said would shame hell, were coming out. She always wanted to fuck. There was something about her face, even then at a few weeks of age, that touched me even though I did not know why. Then, I think if was some time in mid-November, a letter from my mother arrived. She included a few freshly made copies of old photographs, mostly childhood pictures of me, but also two or three images of my father and my mother.One photograph in particular caught my eye. It was a picture of my mother as a baby, taken in 1926. The black and white photograph did not show the hair. May be, she was shy. Slowly I inserted a part my finger into her love hole and started sucking both nipples one by one. As I did not intend to fuck her, I increased my fingering speed and kept on sucking.In a few minutes, she held me strongly and a lot fluid came out of vagina. Clearly, she had received the orgasm which was probably first orgasm of her life. By this time, my wife was super horny. I went back to her and without any delay inserted my dick into her cunt and we had a super strong.
