[All of the sex acts in this story, both directly described and referred to in the past, involve only people who are at least 18 years old.]
Every morning I fuck my mother on the beach. I bareback her, and she isn't in menopause yet. But by the time I fuck her, Dad has already loaded up her vagina with so much of his sperm that mine can't impregnate her. That's an absolutely true scientific fact.
Most of today was like most other days. One part was different. I'll get to that later.
Mom and I strolled from the back deck of the house onto the pristine white sand, hand in hand. Mom carried her beach bag, I carried the roll of four large blankets. The breeze fluttered her long blond hair and the filmy cloth of her floral-print sundress. The touch of her fingers in my palm quickened my pulse and engorged my cock.
She smiled at the bulge in my swim trunks, and said, "I'll enjoy doing something about that."
"That'll be very nice," I said bashfully. No matter how many other women I fuck, in private or right out in the open, I'm still shy around my mother--until my prick gets deep into her warm, wet pussy, and then I'm the man she wants me to be.
I spread the blankets on the sand, to form the arena of pleasure for our family and friends. Behind me I heard my sister laughing at one of my father's jokes, as they followed us. Then I returned my attention to what mattered most, as my mother pulled down my trunks, and the sea breeze stimulated my penis as it sprang upward.
"Such a lovely sausage," murmured Mom as she knelt before me. Then she said no more, and slid her moist lips along most of my length, teasing the foreskin with licks and nibbles.
When she first claimed my cock, on my eighteenth birthday, I nearly passed out from the pleasure. Now, after a year as a grown man, I was much more poised. I was able to enjoy the sight of my sister being denuded by my father, while I crooned, "You're the best, Mom. Of all the women who have sucked my cock, you bring out the greatest fire of passion!"
She drew back her head, leaving her drool to run down onto the blanket, and chuckled at me. "That's very sweet, Dear, and maybe even true, but so many more women will suck your cock in the coming years. And it doesn't bother me at all that some of this mighty erection is the result of you staring at your naked sister."
Busted! I was, in fact, enjoying the sunlight on Sis's right breast, the bright peach tone of her skin set off dramatically by the rich crimson of her wide areola and thrusting nipple. This was about all I could see at the time, because her left breast was blocked by Dad's head as he sucked it, and her pussy was behind the fingers that Dad shoved into it. I will say that Sis's face was glorious in its joy, yet she stayed on her task of yanking Dad's expanding dick.
Mom stood up, and as she did I grabbed her sundress and hauled it up over her head. She was in her black bikini, instead of nude. I knew she had worn it just to make our fucking more of a slow burn, adding several seconds to the buildup. There was already cheering and applause from the other people on the beach, just from this much of Mom's reveal.
Mom's long, wavy blond hair tumbles to the middle of her back. Her gorgeous blue eyes and red lips adorn a face that shows no signs of age. Her colossal boobs enter a room long before the rest of her. A wasp waist gives way to killer hips and ass, above mile-long legs. I'd jerk off to the sight of her, splattering everywhere, if she didn't insist that I stick my dick inside her honeypot.
She embraced me, pinning my erection up between our bellies. Her hands stroked my back down to my butt. As I unhooked her top, she whispered into my ear, "You should know that Dexter and Mindy are coming over today."
That froze me for a second. "Dad knows?" I asked.
"He does. He says we'll all just have to deal with it."
I nodded, shoving her bikini bottom down as I knelt. The aroma of her sex, its rose-pink lips swelling behind yellow tufts, almost made me cum. I took a breath to calm myself, then kissed her divine divide. Then, reaching around to grip her butt, I was able to press my mouth firmly and drive my tongue inward, to find her nectar. I didn't cum, but my dick flexed repeatedly.
"Ooooh," said my mother, stroking my hair. "You're such a fine lover now. So many other women enjoy you, and I hear great praise for your exploits. But I'm so happy that you are still so ardent for me. A mother seeks her son's desire just as much as a son seeks his mother's."
With my free hand, I reached up to squeeze one of the breasts that shaded my head. I kept lapping and drooling, although I wanted to praise her taste. This is one of the benefits of sex with many women: Enjoying a wide variety of vaginal flavors.
Gently pushing at my head, Mom stepped back from me. "You have me right on the edge, Reginald. Please fuck me now. Be assured that I will want more from you, even when your step-brother arrives."
Mom smiled and waved in response to even louder cheering, and turned this way and that to display her marvelous nudity with nothing to block the view. Then she stretched out on her back, on our field of blankets, and threw her legs into the air in a V-for-victory. I settled in above her, as her missionary. My rigid cock slid smoothly between her labia, and gloried to the slick heat that swelled along the entire depth of her tunnel.
"I love to look at you, Beautiful Boy!" said Mom. "Your father and I made you so you can give me endless pleasure." Oh, her wide smile, and the rising promontories of her nipples! Because of how big her tits are, I had to grab them out of her armpits as I leaned over her, so I could suck them. And how I sucked! Left, right, left, right--
My sister howled, "Yeah Daddy Daddy I'm cumming cumming so hard!" I glanced to my left and saw Sis riding my father in reverse cowgirl. Now I could see all of her. Both tits, almost as big as Mom's but higher and firmer, jounced along with her fluffed-out blond hair. With her legs spread around Dad's hips, her flat tummy and shaved belly were now lit by the sun, as was the white gunk spilling out of her pussy around the base of the massive dick. Dad always has plenty for Sis, even after waking Mom up with a bang or two.
Mom was more subtle in her ecstasy. Murmurs escaped her lips while her breasts shuddered in my mouth, and spasms throttled my wang. Undeterred, I drove deeper into her, past her cervix, onto her A Spot. There I began spewing my semen, celebrating her inner beauty while I sucked shamelessly her outer beauty. Every man at the beach wanted her breasts, and perhaps many of the women. For this moment, however, these bodacious boobs were all mine. I had earned them, by giving this amazing woman an orgasm that sprang from her clitoris, vagina, and breasts, to the entirety of her body.
But I'm a polite young man. When other people beg to suck Mom's tits, I give them a few minutes. And other tits were becoming available to me.
Dad said, "I'm going in to have breakfast." He and Sis were now standing together, and he kissed her and headed back to the house.
Sis looked after him for a moment, then said, "I hope he's not worried about Dexter and Mindy."
Mom, on her way to her next orgasm from my fucking, chuckled. "No, Dear. He's hungry." The rest of us had already eaten. Food, that is.
To distract Sis (of course, only for her sake), I said to her, "I'd like to gobble on your tits."
She knelt next to me as I moved my knees under Mom's butt, so I could continue fucking but also rise up. "Okay," said Sis, "but only if you fuck me, real soon."
I didn't make any promises. I just started sucking my sister's tits. They're enormous by any objective standard--and because she's young, just a year older than my nineteen, they're soft but sturdy. They often push up and out of whatever top she's wearing, which is why she usually goes topless, or, as she likes to say, topfree.
We're a close family, but our sex styles vary. I'll fuck pretty much any woman, anywhere, any time. Sis much prefers outdoors to indoors, which is why she didn't follow Dad back to the house. Dad's reverse cowgirl with Sis is part of his respect for Mom. Doing Sis that way, or doggystyle, keeps him from seeing the face and tits of a younger version of Mom during the sex act--while still acting as a proper father, by fucking his daughter, building her confidence as a woman. This also keeps Dad from getting Sis pregnant. That's another absolutely true scientific fact.
My sucking of her young, bulging nipples boosted her libido, and Sis started whining for me to fuck her. "I haven't had your cock in my twat since last night in the hot tub!" she moaned. "And you only jizzed in me twice!"
"Mind your manners, Clarissa," says Mom, "Reginald is still fucking me, and I've only had three orgasms so far today. Besides, you have eight boyfriends right behind you, pulling their puds as they stare at your twat, so be a good girl and spread your legs for their big purple erections."
"Oh all right," she said, taking her tits out of my mouth. She went elsewhere on the blankets, and assumed the classic posture on her back: Two of her boyfriends spit-roasted her, while she jerked two more. The other four stood surrounding her, yanking their cranks until Sis's train would arrive at their stations.
Mom's sex style is more conservative than that. When I'm fucking her, mine is the only cock doing her. The closest she gets to group sex is allowing other people to suck her tits then.
"Goodness me, Miriam," said Mrs. Hardwick from next door, just arriving at the beach. "How big is that boy of yours?"
"Eight inches long, most days," said Mom. "Five and a half in diameter." Then she started roaring her latest orgasm, which startled the two guys sucking her tits. It always makes me very proud, that I can set off sexual fireworks in the pussy that brought me into the world. This is why all men fuck their mothers, to get their cocks back where they really belong.
"He's that big?" gasped Mrs. Hardwick. She put her hand inside her bikini bottom.
"It's why I married Arthur," said Mom, catching her breath, "after poor Otto passed on. I knew that I could help Arthur's spire be carried to the next generation."
Mom managed to focus her eyes, and direct them at Mrs. Hardwick. "I keep telling you, Mavis, Reginald is every bit as powerful as Arthur, and he has the endless energy of youth. My husband already has fifteen women in his harem, besides you and me, but Reggie only has four girlfriends. And they're not even here yet this morning. You should ride my son's pole as soon as I cum again."
"I'd be glad to service you, Mrs. Hardwick," I said, because my parents raised me to be good, giving, and game.
"I couldn't do it right out here!" said Mrs. Hardwick, removing her bikini top, revealing the glorious bounty of her dark brown bosom. "My Edmund, he expects me to be fucked by Arthur, who's a grown man. But a mere stripling? With a hundred people watching? It would shame Edmund terribly!"
"Oh don't worry about that, Mrs. Hardwick," said Sis brightly, with globs of semen oozing down her smiling face. "Mr. Hardwick fucks me every day at the ice cream parlor, when I serve him his banana split. He never seems ashamed about that."
