I am Jack. I came home from college during a week long break and I saw something that changed my life.
I wasn't supposed to be here on Friday evening, I was supposed to take a bus on Saturday morning and reach home mid-afternoon. But I friend who was going my way offered me lift till the highway stop just ten kilometers from my town and I hopped in to his jalopy. It was a fast ride, it was just after nine when I reached home, I had my own key still from the old days when I lived here I opened the door and went in.
I saw that the living room lights were off, an indication that either there was no one home or already in bed. It seemed a tad early to be in bed for a Friday night so I guessed there was no one home. I walked up the stairs, my duffel bag in hand and passed my mother's room. The door was slightly open, as I walked to my room a couple of doors away I heard a moan and in unmistakably my mother's voice. "Oh Liza I am coming, baby, oh yes!"
Liza was my eighteen year old kid sister. But the sentence seemed so incongruous that I first though I heard it wrong, even if I heard it at all. I tip toed to the door and peeped in. There was a sight made for horny nineteen year olds. My mother was spread-eagled her legs apart and knees up and naked. My sister, her butt raised up alluringly, her head buried in my mother's pussy was lapping away. I could even see the half open lips of the cleanly shaved pussy of my sister.
I don't have to mention it but I had a raging hardon by now. I decided that if the two could do it together, they would mind a third joining in. Obviously incest was not a taboo to my family. I knocked at the door. Liza jumped from her pussy licking and tried to hunt for cover to hide herself and her rather beautiful melons from my prying eyes.
My mother was paralyzed in shock. I looked at the place that had been previously hidden by my sister's head. A beautiful, bald pussy, all wet and the clitoris standing tall.
"Well, well, well." I said sitting on the edge of bed. My sister had found a pillow and was holding it hugging to herself. I reached forward and pulled it from her. "There is no need for shyness now, is there. How long has this been going on?"
My mother at last found her voice and movement. She got up into a reclining position and still not trying to hide anything or even bring her legs together.
"It had to happen, don't you think? We wanted you to be a part of it, but were afraid to ask."
"Afraid to ask? Why afraid to ask a horny teenager who has gone to bed after imagining you and shagging off? But since it is out in the open what do you want to do with this horny son and brother?"
"What do you want, big bro?" My sister piped in.
"Now that is a good question Liz. I want you to go back to what you were doing and let me decide. I liked what I saw in that position." I grinned at her.
"Come on." I said seeing her hesitate. She went back to her licking mom's pussy. I sat there and held one of mom's huge tits and Liza's one tight one. One felt like a water balloon and the other like a ripe mango.
I noticed now that Liza had a nice design tattooed on her lower back. I removed my shirt and had my mothers palm running over my chest and hardening my nipples. I ripped my pants off and removed my boxers. Liza came up from mom's pussy to look. Her eyebrows raised appreciatively at what she saw. I took her one hand and placed it on my throbbing cock and let out a grunt as the feeling of her palm made me horny.
"You like it sis?" I whispered hoarsely. She nodded. "I want it in you tight pussy, sis. Is your pussy tight or have been fucking around a lot lately? Don't tell me, I want to find out for myself." I climbed behind her and ran my hand over her crotch, it was soppy wet. I spread the lips and slid a finger in, it was hot and steamy and even for my finger damned tight.
I was in for some nice tight snatch here. I had been fucking around at the college too. I was good looking and my seven and a half inch and thick dick made me quite popular. Even a gay fella asked me if I would let him suck my dick and hammer his ass. I said sure just out of curiosity and even though had a pretty goo fun I knew men were not my type.
I like the look of a female ass better, I like to feel to nice tits with my hands. I was, certainly, a heterosexual. I aimed my cock at Liza's pussy and slowly slid in. The pussy resisted and then engulfed me like a glove. I slid in into her till the hilt and stopped to momentarily enjoy the feeling of a throbbing cock dance with a throbbing pussy. I leaned over and looked at mom in eyes. "Hey mom, like what you see, you son's cock is buried deep inside your daughter's cunt. And it feels great mom. The best pussy in the world."
The two girls moaned in unison. I started to fuck my sister. Slowly building her up to a rhythm and going faster and faster then slowing down to calm her and myself down. I last a long time. Well at least that's what some of the girls have told me. So measured once and decided to see how long I could fuck a girl without coming. I timed myself to two hours twenty eight minutes. That was a exceptional effort of course, but normally an hour is the case.
Hardly half an hour had passed, Liza had come several time and fell onto mom limp, blacking out with her final climax. I shoved her aside and told mom to ready herself. I plunged into the hole I had come into this world from. Her legs up against my chest, her huge tits jiggling. She was almost as tight as Liza and more spongier and wetter. I hammered away in pure delight. She came several time and I was getting near exploding too. I had different thoughts.
"Mommy darling, I love you very much and want to come inside you a thousand times, but right now I want to leave my seed in Liza. It has been a fantasy for me filling her pussy up. You don't mind do you?" I reached forward and kissed her.
Liza was now on her back watching us. As I came out of my mom, my cock thicker than before, slick with all the juice, she spread her legs for me. I into her. In the missionary position, leaning forward to kiss her. Little peck lead to wet French kisses. Her moaning into my mouth was terribly erotic.
