After dinner Mom, Grandpa and I sat on the sofa in the living room and watched some TV. Mom was in the middle and we were still wearing no clothes. Pretty soon Mom grabbed both our cocks and started to slowly jack us off. Now the cocks started to stiffen. Gramp put his right hand on Mom's right breast. I followed him and put my left hand on Mom's left breast and squeezed and rubbed her boob and the nipple which erected to it's full half-inch length. I took the swollen nipple in my mouth and sucked which made Mom jerk and moan. Just then I noticed that Gramp put his lips on Mom's other boob and put his right hand on Mom's cunt rubbing the hair and the mound and then he put his middle finger between her cunt lips and as he touched her clit Mom jumped and moaned at the same time, "Oh Dad, I am so wet, now fuck me, I want to come with your cock in me."
Gramp smiled and said, "yes baby, I'll fuck you good."
Mom got on her hands and knees giving Gramp her upturned open ass and cunt. That sight got Gramp even hotter and he wasted no time in lining up his rigid cock between Mom's wet cuntlips and entered her with a slow but steady thrust. Mom was pushed forward as Gramp got inside her to the hilt and her mouth touched the tip of my cock, she opened her lips and took my cock deeply in her mouth. Now Gramp started deep in and out thrusting into Mom which moved her body back and forth so it looked like I was fucking her mouth. Gramp was using his hands on Mom's waist to push and pull her cunt onto his erection while I was squeezing Mom's jiggling breasts with both my hands.
Such vigorous two-ended fucking produced its inevitable result with all of us moaning and groaning.
Gramp hissed, "I am going to come soon, get ready to receive my hot cream in you baby".
Mom could only thrust back with more force. I was not far myself, the deep rapid suction of Mom's mouth on my painfully hard cock was rapidly bringing me to climax. As Gramp pulled Mom by her waist to his crotch and started to ejaculate his hot semen in her, my cock also erupted its cream in Mom's mouth. She could just moan in a muffled voice as she swallowed my cock to my balls in a strong suction while her cunt muscles squeezed strongly on her Dad's deeply embedded cock as it filled her cunt with cream.
Before we could disengage we heard the front door being opened and Dad walk in with a shocked look on his face.
But he soon regained his composure and said, " Hi everybody, I see you are having a lot of fun."
Gramp and I remained silent not knowing how to react.
Mom took her mouth off my cock and said smilingly, "Oh honey, you are home, come join the party."
Dad smiled too and said, "I'd love to, let me get my clothes off."
Dad dropped his clothes in a hurry, his cock was already hard and it was a good size. Mom moved and Gramp's cock came out of her cunt with a plop. Before his semen could ooze out of Mom's cunt, she sat back between the two of us and opened her thighs and Dad just walked upto her and shoved his erection into her with one strong thrust that made a slushy sound as Mom's cunt was still full of Gramp's cream. As he kept a steady deep thrusting going into Mom, Dad got hold of my slippery cock and commented, "you got a man-size cock son, I am sure your Mom will be very satisfied with that for a long time.
Mom said, "my Dad and son have fucked me so much my cunt was getting sore but in a nice way. Now with three cocks to fuck me I won't need my dildos anymore".
Dad thanked Gramp for agreeing to help satisfy Mom but he was surprised that I was fucking Mom too. But he was happy about that.
Mom brought up a question that caught us by surprise. My sister Shoma was going to school in a town about 2 hours drive from home. She just graduated and will be coming home in a couple of days.
Dad said, "well Mintu and Gramp can go and pick her up while I spend some time with my wife.
