It was the hottest night of the year and I could not sleep. The humidity was overwhelming and it did not help much that I had my bedroom window and door open.
There was no breeze.
I got out of my bed and went to the window. The smell of ocean and wet grass filled my nostrils. I tried not to think about the sounds of sex coming from my parents' and my sister's rooms.
My sister was as loud as usual, begging her boyfriend to fuck her faster and harder.
"Fuck my goddamn cunt you beautiful sonofabitch," she shouted. "Fuck my fucking brains out! Give it to me harder. That's it baby ... right there ... pound my fuckhole with that big cock ... ah shiiiiiit! Make me come ... make me come ... make me ... fucking ... come!"
I imagined her beautiful and sexy body lying there on her bed, her long blond hair all over her pillow and bed sheets with her legs wide open and her handsome boyfriend driving his big cock into her hot pussy, pounding her pretty cunt slit harder and faster, just the way my hot twenty-one-year old sister liked it.
This was not the first time I was imagining her in that way. As soon as she turned eighteen she started dressing like the sluts on MTV. Sexy halter-tops, cut off T-shirts that showed her sexy flat stomach and low cut jeans that revealed her thongs, her lower back tramp stamp and even the top part of her pubic hair, were her favorite pieces of clothing.
I assume that if my parents had not been so liberal and relaxed about sexuality my sister would have driven them crazy.
But they did not mind a bit how my sister dressed or how active her sexual life was.
After all my parents are very active swingers.
I loved watching my sister's antics and as time went by I became more and more fascinated by her, almost as much as I was fascinated with my beautiful mother.
Everyone says that my sister is a younger version of my mother and I absolutely agree, although they should add sluttier to younger ... and definitely much crazier.
They also say that my mom looks exactly like Sharon Stone. I can see the resemblance, but I think that she is much hotter than Ms. Stone.
Age has been very kind to my mother. In her late thirties she looks much more youthful and hotter than most sexy twenty-year old women and she knows how to look good. She has perfect teeth and a lovely smile, always uses the perfect amount of make up, not too much and not too little.
Her breasts are the perfect size, not too small and not too big and naturally firm. She always gives credit to my father and their loving marriage when people ask her how she manages to look so good.
My parents always discussed their lifestyle openly with my sister and me. They always said that having sex with others in a group setting had allowed them to discover and love each other more deeply.
Up until that night and the events that followed I did not completely understand what they meant by that.
I stared into the dark of night trying to get the images of my mother and sister naked and having sex out of my head, but the more I tried the clearer those images became.
I was so fucking horny!
My cock started throbbing and in less than a minute became as hard as a rock. I thought that my parents must have left their bedroom door open because I could hear my mother's soft moans in between my sister's louder cries of ecstasy.
I wished that I could call my girlfriend to come over, but she was out of town for a few days. My heart started beating faster and I felt light headed.
I was getting too damned hot and needed to cool down. I left my room to go to the bathroom down the hall. I was right. The door to my parents' bedroom stood ajar and it looked like that they were having sex with the lights on.
In the bathroom I splashed some cold water on my face.
It did not help much.
I looked at myself in the mirror. My face was flushed and my cock was about to rip my boxers open. I pulled down my boxers and splashed some water on my cock. For a short moment I admired my own body and my big throbbing cock.
I have inherited my parents' extremely good looks and my father's muscular genes. Just like my father I have a very muscular and well-toned body, dark blond hair, blue eyes, six-pack abs, big biceps, broad shoulders and pecs, strong legs and an eight and a half inch cock.
I left the bathroom and started towards my room. I glanced at my parents' bedroom door. The image of my naked mother popped into my head once more. Before I knew what I was doing I was right next to the open door of my parents' bedroom. One more step and I would be able to look inside.
I took that step.
I saw my father's muscular butt going back and forth, up and down. He was holding my mother's ankles wide apart and fucking her very slowly.
His muscular back and buttocks were glistening with sweat. His movements were glorious and rhythmic. Every few pumps he would lie on top of my mother silently and kiss her, making her moan into his mouth. My heart was pumping too fast and my head felt dizzy with thick and pure lust.
For less than a second my legs turned to mush, I lost my balance and stumbled head first into the bedroom. I caught the doorknob and prevented a complete fall.
When I finally regained my balance inside the bedroom and was able to look up, I found both my parents looking directly at me.
My father had turned his head and my mother had lifted her upper body using his shoulders. Seconds passed as if they were minutes.
My parents looked surprised but to my relief they did not look angry at all.
"I ... I'm sorry," I managed to mumble. "I'll ... I'll leave now."
"No!" I heard both of them say in unison.
I thought that I must have heard wrong. I turned and started to leave when I heard it again. First my mother and then my father, "No!"
"Don't leave honey," my mother said softly.
Impossible, I thought, they want me to stay?
My father was smiling faintly. He was definitely not angry with me ... and he was staring at my hard on, so was my mother!
I had forgotten about my hard on, but now I was painfully aware of it. I tried to cover it with my hands and it must have looked funny to my parents because they both started laughing.
"It's ok baby!" my beautiful mother said, grinning impishly.
I found myself laughing nervously as well and removed my hands from my hard on.
"That's more like it," my mother said. "No need to hide that beauty from us."
"No there's no shame in having a nice healthy hard on son," my dad added. "Come on closer and watch. You might learn a thing or two from your old man."
"Or you can give your old man a few pointers," my mother chuckled and playfully licked my father's nose.
This is too fucking crazy, I thought.
I knew that my parents were cooler and much more relaxed about sex than most other parents, but to invite me to watch them fuck was not something that I expected in a million years.
They kept watching me intently as I slowly stepped toward their bed. As I got closer I finally could see my mother's beautiful body, her nakedness in all its glory.
My fucking hot mother is naked!
Her bare breasts were the most beautiful breasts that I had ever seen. Her long nipples stood erect gloriously and her dark blond cunt bush was covered with beads of sweat and possibly her own cunt juice.
The hot pink lips of her pussy had engulfed my father's thick cock and I could see her erect clit throb wildly like a miniature cock that was about to harden.
I was standing so close to the bed that my legs were touching the side of it. My dad started to pump my hot mother's pussy slowly but firmly again. His cock started to make wet sounds as he pumped it back and forth inside her.
Squish! Slurp! Splash!
"Wow!" my father exclaimed. "Where did this flood come from?"
"Mm ... what?" my mother whimpered, looking straight into my eyes.
"You weren't so fucking wet a minute ago," my dad panted.
"What's your fucking point?"
"No point. Just an observation!"
"Sounds more like an accusation," my mother giggled throatily.
"Maybe you're right."
"You're a sexy little pervert ... getting so fucking wet because our son is watching!"
"Shame on you!"
"Shut up and fuck me harder!"
My handsome father's big balls started slapping against my mother's butt cheeks. His shaft looked very wet. My mother's brow furrowed as she turned her attention to my father's pumping dick once more.
"That's it baby," my mother purred. "Right there! Fuck that pussy. Fuck it baby. Fuck me!"
She put her beautifully manicured fingers on my father's abs and started moaning.
"Ah ... fuck me with that beautiful cock of yours!" my mother cried as she lifted her ass off the bed, bucking her hips wildly against my father's crotch.
"Oh Jesus," my father gasped. "If you keep this going I'll come in less than a minute!"
"No!" my mother shouted, putting her ass down on the bed again. "Don't you dare come so fucking soon!"
My cock was throbbing again and becoming impossibly hard. I felt some pre-cum escape the tip of my cock and wet my white boxers.
"Why don't you take your boxers off baby," my mother said as she looked up at me. "Come get closer o us. Get on the bed ... oh I love the way your dad fucks me!"
Both of them smiled at me as I shed my boxers and climbed on the bed right next to them on my knees.
"Look son, this is how you fuck a nice pussy," my father said as he continued to fuck his cock into my mother in slow motion. "Sometimes you go really hard and fast," he continued, "and sometimes nice and slow like this. I've been fucking her like this for almost half an hour now."
"Don't be so shy honey," my mother mewled. "Go ahead and play with your cock. I know you want to!"
I wrapped my fist about my cock and started stroking very slowly. I was afraid that I would shoot my cum all over my parents if I stroked any harder. I was not sure if they would like that. I was not sure about anything for that matter.
I was still very tense, but horny enough to try almost anything. Suddenly to my surprise my mother craned her head and moved her face extremely close to my hard cock. She stopped just short of her lips touching my cock.
She spat right on my cock head. A thin string of white saliva now lingered between my cock head and my mother's mouth.
"There you go," she said with a smile. "You looked like you needed some help with that baby."
"Thanks mom," I replied nervously. "I did need that because my mouth is kinda dry!"
"See ... that's why I love her so much, always thinking about helping others," my dad said and leaned down to kiss her lovingly on her beautiful lips.
They kissed hotly and passionately and my mother made sure that I watched as she sucked on my father's tongue. I really wanted to kiss her too but I was not sure where they would draw the limits.
It was one thing to watch them and play with myself while doing so, but maybe I was not allowed to touch.
I decided to test them and see how far they would let me take it.
When my father finally was done kissing my mother and started fucking her again I slowly put the palm of my hand on my mother's sexy, flat stomach. Her beautifully tanned skin felt very hot to the touch, almost as if she had a fever.
I looked at my mother's beautiful flushed face and there it was again, those beautiful eyebrows frowning with lust.
I soon grew bolder and started moving my hand up and down her stomach, from right beneath her breasts to the outline of her pubic hair.
"Oh fuck yes baby!" my mother purred. "Touch me! It feels so fucking good ... so loving. Don't be shy honey. You can go lower if you want to!"
I saw the look of approval in my father's eyes and my fingers touched my mother's curly blond pubic hair. She started moaning louder as I took a handful of her bush and gently pulled on it.
"Ooh god yes ... yes please," my mother cried. "Pull harder honey. Fuck! Are you watching this Dan?"
"Yeah sweetie," my dad replied. "I see it. He's finally warming up."
I ran my hand up her body again. This time I stopped right under her breast. I put my left hand on her head and started caressing her beautiful hair.
She looked directly into my eyes and I saw tears welling inside her big blue eyes.
"It feels so good," my sexy mother moaned. "Keep touching me honey. Keep tugging my pussy hair!"
I lifted my right hand and put it down again on top of her breast. I took her stiff nipple between my thumb and index fingers and pulled on it.
My mother started breathing very heavily as she put her hand on my butt cheek and dug her fingers into my muscular ass.
"Oh shit!" my mother cried breathlessly. "Ooh fuck!"
Her body suddenly stiffened. She clenched her jaw and stopped exhaling. At the same time she raised her hips to meet my father's thrusts.
Tears of lust and unbearable joy started rolling down her flushed cheeks as I pulled harder on her stiff nipple.
"That's it Jake buddy," my dad announced. "She's coming son! You've made your mother come!"
My mother finally exhaled and lowered her hips. She let out a sexy sound that was somewhere between a moan, a purr and a beautiful melody.
I smiled at her and she smiled back at me.
"Oh my god!" she exclaimed. "That was so good. So fucking intense. Don't you dare stop touching me now my beautiful boy! Make me come one more time Jake! I love the way your hands feel on my body!"
I put my left hand on her breast and the right one in her pubic hair. I pinched her stiff nipple hard and pulled on her thick curly bush even harder.
She started panting heavily again and my dad started thrusting his thick cock into her with longer and firmer strokes. I could see that her large clit was throbbing more evenly.
I touched her clit.
"Ooh god-fucking-damn this fucking shit," my mom screamed at my touch.
I pinched her swollen knob. She raised her hips again.
I pinched harder.
She started sobbing loudly.
Tears trickled down her beautiful cheeks.
My dad fucked her harder.
I pulled on her large swollen clit.
She dug her fingers into my ass crack.
"Harder Jake!" my mother cried. "Pinch my fucking big clit harder. Rip it off of me!"
"Like this Mom?"
"My clit! Mm...my fucking clit! My fucking pussy's on fire! Ooh god!"
I pinched my mother's beautiful and sensitive clitoris even harder.
Her middle finger went right up my asshole.
Her body stiffened and relaxed a few more times before she finally lowered her hips. My dad pulled out of my mom's pussy.
"I don't want to cum yet," he explained. "This is proving to be so much fun. I have seldom seen her cum so hard son. Looks like you have the magic touch."
My mother let out the same sexy sound as the previous time. She pulled her finger out of my asshole and put it into her mouth.
She looked into my eyes as she sucked on her finger, savoring the taste of my asshole. She smiled at me again and then looked at my father.
"Dan, go get June and Rick!" she commanded my father. "Run baby. Don't waste any time. I'm so fucking horny."
My sister? She wants my dad to get my sister and her boyfriend? Wow!
I could hardly believe my ears. She wanted my sister and her boyfriend to join in. My father jumped out of the bed and left the room in a hurry.
I was alone with my naked hot mother. She sat up and leaned over my hard cock. Her nose was right above my throbbing dick.
She smelled it as if she wanted to savor the fragrance of my cock. Then she flicked her tongue out and licked the very tip of my cock.
Her hot tongue touched my piss-hole!
It was just one quick lick. I suddenly felt light headed again. I was delirious with lust. I was not sure if I was dreaming or all these things were really happening.
My father finally came back and had a sheepish look on his face. I thought maybe June and Rick had declined his invitation. But if I knew my sister she would jump at the opportunity to watch my parents fuck and would not miss it for the world.
I was right.
A few seconds later June and Rick entered the bedroom. June looked as hot as always except that she was wearing only a cupless bra and no panties. Her cunt bush was the same color and as thick as my mother's. Rick was sporting a huge hard on and had a grin on his face.
"Fuck me!" my sister exclaimed. "Jake is here too? What the fuck has gotten into you people tonight? I thought that you were putting us on or something."
"No sweetie," my dad explained. "Now you see why I told you not to get dressed."
"Well excuse me Mr. Daddy," my sister replied sarcastically. "I was not going to get dressed anyway since you showed up in my room with your cock standing up like that."
"Yeah Dan," Rick added. "You kinda scared the shit out of us barging in butt naked like that!"
There was a moment of uncomfortable silence.
We were all looking at each other and nobody seemed to know what to do next. I was hoping that my parents would not change their minds and send us right back to our rooms.
My mother shifted her position on the bed and leaned against the headboard. She spread her legs wide open, which received everyone's full attention.
"June, honey climb on the bed and lean against me," my mother said lovingly. "I want to hold you and play with your gorgeous tits while your beautiful boyfriend fucks your hot pussy. Dan, get Rick's cock ready for your sexy daughter, then put it inside her!"
I watched in complete disbelief as my father grabbed Rick's cock by its root in his fist and started jerking it.
My father is bi-sexual, I thought to myself. Unbelievable, but so fucking cool. My dad's fist is pumping Rick's cock!
Rick seemed a bit surprised at first, but soon let the pleasure of my father's loving fist take over his body.
I felt a new sensation brewing in my head.
My dad stopped pumping Rick's cock and pulled him closer to my sister, then he put the thick tip of his cock against my sister's now throbbing pussy.
He parted my sister's pussy lips with his right hand and inserted Rick's cock into her with his left hand. My sister yelped at my father's unexpected touch.
"Ooh Daddy," she purred. "That's it. Put it in me! Don't take your beautiful fingers off my cunt ... please!"
"I won't honey," my dad replied lovingly. "I promise I won't."
And he didn't!
My mother cupped my sister's firm breasts from behind and started gently licking and biting her neck and shoulders.
I looked at June's lovely face. Her big blue eyes were dreamy with lust. A cry of pleasure escaped her lovely mouth when my mother started pulling and pinching her stiff nipples.
"Is he fucking you good baby?" my mother whispered into my sister's ear.
"Oh ... yes Mommy!" my sister purred like a kitten. "So fucking good ... Mommy!"
I put my hand on my sister's stomach and stroked it lovingly as I had done earlier with my mother.
I am touching my fucking hot sister!
She moaned and breathed heavily when I started pulling on a fistful of her thick pubic hair. Rick was now thrusting his hips back and forth, fucking my sister's hot pussy with firm strokes.
"Ooh, you beautiful fuckers!" my sister screamed. "You're driving me so fucking crazy. Don't stop touching me. Rick, fuck me harder. I'm gonna come so fucking hard!"
My sister screamed as her body tensed and she came very hard on her boyfriend's thick cock.
My father massaged her throbbing clit, my mom pulled harder on her nipples and I pulled on her blond pussy hair.
When her body finally relaxed again my dad pulled Rick's cock out of her pussy and took it into his mouth.
