Background: We had been married for 9 years, my mother in law had passed on a couple of years back. My father in law (Sam) and I were always close. He always complimented me and would say things like, "My son is lucky to have such a nice beautiful and sexy wife." He would lovingly slap my butt and say "Sure nice one there, baby girl." He always called me "baby girl." I just thought he was like most men, always looking at the women. I often suspected my husband played some but never had any real proof. *** On this occasion, my husband, (Ron) informed me that his father was going to be in town for a company training course for a couple of weeks and invited him to stay with us. I was excited and agreed it was the thing to do. At this time I was a stay at home mom. Son was in school. Sam arrived mid-day and we hugged as usual and he pinched my butt and said, "You still have a nice one Baby Girl." I giggled and said, "Bet you tell all the girls that." "Not really honey. I have tried being nice the last couple of years. I'm thinking of taking care of some of my manly needs pretty soon, though." We moved to the living room and continued our chat. He was saying that he wished he was young like me and I was not married and he would be after me. I giggled and said, "Dad, you are a good catch like you are. Bet you can still swing a mean stick." We both laughed, and he said, "Well I wish I had someone to swing that stick with. It's been two years now without a woman." The next morning I was up early and prepared Ron's breakfast dressed in only my shorty-nightgown. (nothing underneath) After my husband left for work, I was on my way back to our bedroom when I saw my father in law's door was partly open and I peeked in at him. I did not know that he slept naked and he was laying there without anything on and his manhood was standing at attention. I stood there gazing at that beautiful hard pole. I remember what he had said about me and how he had not been with another woman in two years. As I stood there with my rambling sexual thoughts, I realized I was getting wet and horny for what I was looking at. I was rapidly thinking, does he want me? Will be take me? What should I do? I want him, yes I want him! Bet his balls are full and needs to be unloaded! I Gathered my courage and slowly entered the room and sat on the side of the bed, making sure that my shorty- nightgown was up high enough to expose my woman hood, (of course making it look like it was accidental) put my hand on his forehead and said, "Dad, are you OK? He opened his eyes, and looked at me and I saw him glance at my hairy womanhood. He paused and said, "Well I am better now that you are here," and laughed. He reached up and pulled me to him and gave me a sexual kiss. I kissed him back and knew then that there was no turning back as he pulled me on top of him and I could feel his pole as he slowly moved it into position to enter me. I offered no resistance as I was now so hot I would have given in to a homeless man on a park bench. We held each other for a moment and I saw the tears come into his eyes as he said, "Oh Baby Girl, you are so good to me. I need you so bad." I wiped his tears away and whispered, "I love you Daddy. I will be your lover." as I rolled over and he mounted me from the top and we started humping, squirming, and making love. He continued pumping on me and I met each of his stokes with a stroke of my own. He moaned out, "You are making me cum Baby Girl." as I felt him pulsating as he unloaded his balls. I started shaking and having an orgasm like none other I had ever had. I went limp and lay there with my new lover (father in- law, or Daddy as I often called him) on top of me, our sweat mixed and our bodies rested. We lay there for a long time saying nothing. Then he whispered, "Thanks Baby Girl, you have made me very happy," as he moved off and lay beside me. I replied, "I am glad my daddy knows how to take care of his Baby Girl."
