Every family has its secrets and mine was no exception, but how boldly it was expressed that day from the first confession led to an afternoon of debauchery not soon forgotten in my home.

It was a hot summer which meant weekends of cookouts, spending hours by the pool and a party like environment visiting my family, mostly staying in nothing more than our bathing suits and bikinis all day was a blast. Oddly enough last Saturday from the beginning of the day when I arrived there was something in the air, a curious feeling that something was awaiting to unfold. Like every Saturday my mother’s new husband Robert and I had gone out to the gym and when we returned the my sister Amy and mother Ann were already by the poolside just relaxing.

My mother Ann was a tall svelte model of a woman with long flaxen blond hair, blue eyes, ample tits and “curves that went on for days” Robert would say to me, I was no stranger to my mother’s allure that Robert felt comfortable sharing with me. Amy was smaller in stature, but like mother rocked a bikini like no other having large breasts and a curvaceous figure with a vivacious nature that was a deadly combination. “Did you two take a shower at the gym?” mother asked and as we said “yes” she replied “than why don’t you both eat then get on your trunks and join us by the pool?” as her red lips sipped on a mimosa.

“Kind of early for drinking” I thought, but what the hell it was Saturday and mother had already prepared some food on the grill in advance for our return. Robert and I ate first sitting at the table by the grill as the girls sat beside each other talking while we discussed the work out. As we were finishing mother became a bit impatient “come on guys, time to party” and with that Robert and I went upstairs to change into our swim trunks when I had noticed I hadn’t brought mine. Thinking on my feet I had a pair of posing trunks which were like a pair of Speedos basically that covered everything enough.

We met down at the pool where Robert was already there sitting in one of the captain’s chairs by the ladies sipping a beer as he said, “posing trunks, forgot your bathing suit I take it?” I smiled and mother said something to Robert. With that Robert stood up and pulled off his bathing shorts to reveal an actual pair of Speedos saying to me “your mother wasn’t sure the tight suit would be appropriate in mixed company” I laughed. It was the least clothing us guys had ever worn, but both of us had the muscularity to pull it off and the girls seemed amused by it enough to comment throughout our talks.

As I sipped my first beer Amy lit up a joint and passed it around which I was all for, but I hadn’t realized my mother now enjoyed too. I made the comment “I’m surprised mother to see you smoking weed?” as she blew out the smoke she said, “hanging out with your sister and Robert more, I’ve tried some new things and liked them” I smiled at her happy to see she had come around. The girls continued to enjoy the mimosas while us guys drank beer when we noticed the skies becoming dark all of a sudden as Robert exclaimed, “maybe we should move this inside, it looks like it’s going to pour”? We each grabbed something from the tables and took it all inside, covering the open grill and no sooner that everything was inside the skies opened up.

We put the beers in the fridge, the food on the stove and the pitcher of mimosa on the dining room table as we all got comfy I brought two more beers out for us guys. As we sparked up yet another joint the subject of discussion turned to one of a sexual nature which I found unusual. As it became very candid I was having a strange effect sitting there in my tight briefs and the presence of both my mother and sister in their bikinis was making me curiously hard. I had to remain seated while mother confessed her growing interest in the sexual adventures she shared since meeting Robert and that’s when the conversation took the sharpest turn?

Mother turned to me in her high state of euphoria and had explained her growing fascination lately of being “watched” having sex, “only thing is we don’t know any men Robert would trust” she said. I was oblivious at what she was getting to, but not for long when she shared the incident we had engaged in when I was 19 after dad was gone. The whole day mother and I had spent when Amy was away on vacation getting drunk and fucking, I was stunned that she would share it so openly after all this time. I sat in disbelief as I looked at Robert and my sister thinking they were hearing this for the first time too?

Neither of them reacted as I thought they would as mother brushed my hand and said, “maybe this will make you more comfortable”? Mother got up from her chair and walked around behind me to where Amy sat, the look of her beautiful body in her bikini brought back a flood of memories from that day long ago. Amy looked up at mother as she rose to her feet and the two of them pressed their bodies together, their lips locked in a passionate kiss. “What was going on” I couldn’t believe it or look away as Robert rose from his chair and walked up behind my sister untying her bikini top as he leaned into kissing mother.

I was in a surreal moment I couldn’t comprehend as my sister looked over at me in between mother and Robert as they touched her in ways I would have never imagined she would agree. With all this stimulation my cock was raging as Robert pulled my sister away to the far side of the table, slipping his hand down the front of her bikini bottoms and mother turned toward me. As she untied her top and moved closer I felt the need to rise, her massive tits and hard pink nipples caught my full attention. Before we could touch I looked over across the table and there Robert had slipped off my sister’s bottoms placing her ass on the table. As Amy laid back her legs were up in the air with Robert pulling out his big dick and slipping inside her with hard thrust as she screamed!

With mother beside me her hand pressed against my bulge before slipping into my briefs and pulling out my hard cock. “I guess you are in then, I can make it even better son” she said before dropping to her knees and sliding my throbbing dick in her warm wet mouth. Mother positioned herself between me and the table as I sat watching her look up at me with her big blue eyes while sucking my cock wildly, across the table my sister’s pussy being plowed by her stepfather as her tits bounced. My mind was a jumbled mess of debauchery and the taboos being broken simultaneously when mother would up the ante, climbing onto the table before me on her knees while slipping off her bottoms.

As if compelled by an evil force I shoved my tongue into my mom’s wet pussy, my nose brushing against her tight asshole with her ample tush pressing my face. Mother screamed as I licked her sweet twat as deep as my tongue could plunge and then a muffled sound. I backed off for the moment as I realized my sister had turned herself with mother eating her pussy on the table, her head hanging over the edge as Robert fed her his big dick. Mother came up from Amy’s pussy and said, “this needs position needs a tweak” and as Robert pulled out of my sister’s mouth Amy flipped over along with mother.

Mother on her back with her legs in the air gave me an idea of what she wanted as Amy climbed onto her face, mom began licking Amy’s pussy where I could now see it clearly. Bending further down Amy continued to suck Robert’s cock as I guided my swollen cock into my mother’s hot soaking wet snatch. Robert’s eyes gazing across to me, acknowledging the pleasure we were both having as I fucked mom’s beautifully tight wet cunt again. Mother’s hands wrapped around my sister’s ass as she licked her young pussy from under was giving me so much more fire as I fucked her hard and faster.

Mother’s muffled moans of orgasm while this all was happening encouraged the tightening of my balls as I heard Robert groan and grabbing my sister’s head as he filed her mouth with cum. A few more thrusts and my cock was next, exploding inside mother’s wet cunt as it overflowed down the crack of her ass. Compelled to not waste this moment I pulled out and on my knees I licked out my mother’s dripping hairy pussy till her fucking hole was empty. “Oh son” she cried “that was incredible” and as we all finished up after composing ourselves, naked around the table we knew this was only the beginning of something amazing!
