Just the Four of US

(Part 1 from 1)

Note: This story is completely fictional.

My older sister and I lived with our parents in a nice ranch house in a quiet suburb of Boston. Life there was pretty much the same as with any other family except that our parents were a little more liberated. Both were in their early forties, attractive and fit. My sister was a little over eighteen and had a body I had fantasized about on more than one occasion. She had a slim waist, average but firm breasts, and an ass that just begged to be grabbed. I had just turned eighteen and my hormones were raging. It seemed like every time I turned around I had another hard-on. Masturbation was a big thing in those days and three or four times a day seemed to be my average. Thinking about my sister while jerking off was one of my faborite pastimes.

As I said, our parents were more liberated than most. They had no inhibitions about fondling each other in the more public areas of the house; even when my sister and I were home. Dad could often be seen coming up behind mom in the kitchen for example, and giving one of her tits a quick squeeze. Then again, it wasn’t unusual to see mom position herself in front of dad and reach around and give his cock a quick grab. I didn’t know my sister’s reaction to this, but I found it hard to walk around my own home without wearing tight briefs so my bulge wouldn’t show.

One night, after we had all prepared for bed, I gave myself the usual hand-job and came all over my belly. I got up as usual to go clean up in the bathroom when I heard noise coming from my parents bedroom. Like every other night the bedroom door was open slightly giving a clear view of the foot of the bed. This wasn’t anything new. I had often gone by their bedroom and seen them in various sexual positions with them completely oblivious to the fact that I was standing there with a renewed hard-on. 

This time dad was standing at the foot of the bed facing it, and mom was on all fours facing him with his hard shaft jammed into her mouth. She was bobbing her head on is dick as he stroked her nipples with both hands. He was obviously enjoying this very much as evidenced by the look on his face and his hips moving back and forth in rhythm with her head.

As I stood there and watched, I noticed that my own cock was working its way to a full erection and was sticking straight out of the fly in my pajama bottoms. I could just barely see it in the hall, and decided not to do anything with it for the moment and just enjoy the sensation of the ever increasing hadrness. I had been so intent on watching my mom give my dad a blowjob that I hadn’t noticed that someone was standing slightly to my right rear. My erection was on fire as I watched. It was almost as if someone had taken my cock in their hand and was toying with it. Suddenly I realized that someone did have my cock in their hand, and it was my sister. 


There she stood in her oversized tee shirt she always wore to bed. Her right hand was stroking my cock while her left hand was hiding under her shirt and was playing with her pussy. I couldn’t believe what was going on. My dick had never been so hard, and I knew that it wouldn’t be long before I’d shoot all over the hallway wall. Well, given the situation, I wasn’t going to let my sister have all the fun so I removed her hand from her pussy and replaced it with mine and started stroking her clit in time to her stroking my cock. 

My mind was in a fog. My cock felt better than it ever had, and my sister’s pussy was dripping with excitement. Suddenly my mom stopped sucking my dad and let his cock plop out of her mouth. She gave his balls a playful squeeze and said she’d be right back. She got off the bed and disappeared behind the door. A few seconds later, to my sister and my shock and amazement, the door flew open. There was my mom, standing stock naked before us. My dad still had a hard-on and was slowly stroking it himself. My sister had my cock in her hand and had frozen in that position while the three fingers I had worked into her cunt were still in place. What a sight!

My mom was the first to speak. “Well, don’t just stand there with your mouths open, come on in and join the fun.” My sister and I (still holding each other) walked into the bedroom and sat on the edge of the bed. Mom walked over to me and removed my sister’s hand from my dick and said “I’ll bet this gets plenty of exercise. It’s in terrific shape.” With that she wrapped her fingers around my cock and started pumping it up and down. Although it had gone down slightly at the shock of being discovered, it immediately sparang to life even harder than before. Before I realized what was going on, my mom had bent over me and was putting my cock in her mouth while she tugged on her right nipple, making it get hard and long.

I was so busy concentrating on what was happening to me that I hadn’t noticed my dad and sister on the other end of the bed. Somehow, my sister’s tee had been removed. She was sitting on the edge of the bed, her feet touching the floor and her back against a pillow. Dad was on his knees in front of her and was slightly stretching her pussy lips open as he licked her clit until it became fully erect. Holy shit! What a party! Mom was giving me a fantastic blowjob while dad was eating my sister’s pussy, all on the same bed. The smell of sex was obvious throughout the room.

It didn’t take long for mom to get another idea. She moved me to the head of the bed and spread my legs. I must have been a sight with my cock pointing toward the ceiling, but I didn’t care. I just wanted to cum and keep cuming. Mom took hold of my sister and escorted her to my cock, asking “ have you ever tasted your brother’s cock?” My sister answered “Not yet. I didn’t have a chance.” So mom positioned her face over my cock and my sister opened her mouth and took it in. All I heard my sister say was “Hmmmmm”, and from the look on her face she was totally enjoying sucking and running her tongue along my stiff dick. 

Then to everyone’s surprise, mom positioned herself on her back with her head beneath my sister’s pussy and started tonguing her clit. I could feel my sister’s approval in the way she suddenly started sucking with more effort. Well dad certainly wasn’t going to be left out of this. After a while of watching the action and jerking off, he couldn’t stand it anymore. He pulled mom away from the pussy she had been ravaging and put her head next to my sister’s. In a second, both of them were licking and sucking my cock like there was no tomorrow. Not wanting to be left out, my dad came up behind my sister and without much hesitation, rammed his cock up into her pussy. Now we really were making one hell of a show. I was getting a double blowjob and dad was fucking my sister’s pussy. Poor mom was the only one who had nothing in her pussy so she inserted a few fingers and proceeded to finger-fuck herself as she bucked and groaned.

It was all just too much for all of us. We didn’t all cum at once, but it was pretty damned close. I came first, and since my sister was jerking me off and mom was licking my balls, my cum flew all over their faces and tits. Dad was next. He pulled out of my sister’s cunt just in time to finish by jerking himself off while he came all over my sister’s ass. My sister grabbed her clit and got herself off so hard that I saw her squirt all over the bed. Mom was last and she came so hard that she simply collapsed on the bed among the rest of us.

Needless to say this was the beginning of some wonderful family get togethers, but that’s another story for another time.
