I watched in disbelief as my father-in-law fucked my wife - his own daughter - on the bed a few feet away. I felt the urge to cheer as his enormous cock plunged into her frothy cunt again and again. With her sleek legs drawn back and her feet resting on his ass, I had an unobstructed view of the penetration. I could hardly tear my eyes away from it.
My beautiful mother-in-law was on her knees next to my chair giving me a fabulous blow job to go along with the incestuous fuck show. Her beautiful tits drew my hand the way a magnet attracts iron. As I weighed one of her fruity tits on my palm, I marveled at how closely it resembled her daughter's tits. I silently thanked her for passing on one of her finest attributes to her daughter. I had spent many happy hours sucking, fucking and fondling those marvelous melons.
I had called my in-laws Mom and Dad ever since they gave me permission to do so on my wedding day, but it didn't seem appropriate then.
"Mary, maybe you should stop now," I said. "I'm getting very close and I don't think it would be proper for me to come in your mouth."
Her only response was to bob her head faster and to work up a bigger mouthful of spit.
"Give it to her," my father-in-law said. "She loves getting a nice, juicy mouthful of jizz."
A few seconds after he gave me permission to cum in his wife's mouth, I fired a burst of cock-custard against her tonsils. She gagged but quickly recovered and took everything I had to give. My wife's pretty head was turned in my direction so she could watch me unload in her mother's mouth. The expression on her face was probably very close to the one on mine. We were both coming!
But I am getting ahead of myself. I met my wife Laura in my senior year of college and we began having sex after a couple of dates. One night when I was fucking her on the back seat of my car, she told me how her father had fucked her as soon as she became a woman. She told me that he had an enormous foot-long cock and that he used it like a master. I didn't believe a word of it. I thought it was just dirty talk to make me horny, and that's exactly the effect it had on me. Each time we fucked, she would tell me about one of her sexual experiences with her father. I pretended to believe her, even though I was convinced they were only fantasies.
It wasn't until Laura and I married soon after graduation that I finally met her parents. They made a lasting impression on me. Both were exceptionally attractive and charming. Mary was a statuesque brunette with an angelic face and dazzling smile. Bruce, her handsome father, could have been a leading man in the movies. Mary began flirting with me even before our first handshake ended. While Mary distracted me, Bruce and Laura disappeared for a half hour. I was more than a little peeved at my new bride for abandoning our guests. Perhaps if I had known that Bruce was fucking her brains out in an upstairs bedroom, I would have been more understanding. When my beautiful bride returned with a big "I've just been fucked" smile on her face, I began to suspect that the stories she had been telling me were not fantasies after at all. But it wasn't until Mom and Dad came to visit us on a holiday that I knew for certain that the stories were true.
We were in the livingroom one evening having drinks and a chat. I sensed that something was up and that whatever it was, it was big. One by one they slipped away until I was watching TV by myself. I nearly jumped out of my skin when the phone on the coffee table rang. It was Laura calling from the guestroom phone. "Come to the guestroom, darling," she said.
I suppose I knew what they were up to even before I opened the door and saw them lying naked on the bed. Dad was between his wife and daughter with his enormous cock resting on his belly. Laura reached over, took it by the base, and pointed it straight up to show off its size. The huge member towered a foot above his belly.
"I told you Daddy was hung. Do you believe me now?"
A few minutes later we were going at it. I've already told you about part of that and now I'll tell you the rest. After I finished coming in Mom's mouth, she swished my sap around for awhile as though she were savoring a fine wine. She finally took it down in two or three gulps.
"Thank you, dear," she purred. "That was delicious. I can usually judge a man's virility by tasting his semen, and my guess is that you have a very high sperm count. When are you going to tell my daughter to stop taking the pill so you can pump your seed into her and make me a grandchild?"
"Well, I, for one, am very glad she is still on the pill," Bruce said. "I'm about to shoot and I would hate to have to pull out."
No sooner were the words out of his mouth than he came. A loud groan escaped his lips and his body shook from head to toe. Father and daughter were locked together, their limbs intertwined. My adorable wife whimpered like a frightened child as one orgasm after another racked her body. The two finally went limp in each other's arms.
"Oh, Daddy, thank you," she said. "You made me come so hard. My sex muscles are going to be so sore tomorrow."
After chiding me about not giving her a grandchild, Mary immediately went back down on me to keep me hard for what was next on the agenda. She soon gave me an even better hard-on than the one I had had earlier.
