"Hey huuun!" Marilyn loudly exclaimed in a purposefully high-pitched voice as she surprised her 20-year-old nephew, Sean, by jumping at him from behind and clasping her arms around his chest, hugging him tightly.

"Hey Marilyn, what's bringing you to the kitchen," he blurted out, saying the first thing that came to his mind in a vain attempt to try to break some of the awkward feeling caused by his aunt's quite well-endowed body clutching itself tightly to his.

"Hmmm, nothing," she said in the same high-pitched voice from before as she hugged him tighter, enjoying the feeling of her massive breasts squeezing themselves against his solid back, with the soft fabric of her bathrobe being the only thing separating their bodies. Given the way his heart was beating and the deep breaths he was taking, she highly doubted he didn't enjoy the feeling of her body clutching to his as well, though he understandably felt awkward. "Just thought I'll say a ´Hi´ to my handsome nephew, and maybe nab myself a cookie or two, like you're doing I bet," she added with a laugh.

"Well, OK," he replied, sheepishly, as she giggled and let go of him.

After milling about the kitchen for a few moments, she sat by the table in the center of the room, on the chair closest to him.

Checking out his young, muscular body, she asked with a giggle, "Do you know where the others are? I got a little scared when I woke up and it looked like I was the only one in the house." Her eyes still locked on his body, she continued, "At least where Shawn and Henry are, I'm not gonna get mad if you don't know where your uncles are."

"I think Dad's out in the garden, don't know where the others are, maybe they went to buy groceries and stuff," he said with a shrug. "There's six of us, things get eaten quickly here."

She giggled again as she felt her pussy tingle a little at his mention of things being eaten in their house, which was quickly followed by a sudden sour feeling as she forced her gaze to finally leave his body.

She didn't understand why she was reacting this way.

There was simply something

different

about the atmosphere in their home today. The air felt, in some indescribable way, almost electric. She felt it for some time before as well, but today it was especially strong. She couldn't even really put a finger on it, but it was a feeling she couldn't shake off, no matter what.

She felt, weirdly,

happy

?

Slightly air-headed and rather ditzy, as if she was looking for something or trying to remember something that kept escaping her, and most of all, she felt weirdly horny.

Not that she wasn't used to feeling horny but, as she found herself fighting her eyes to keep them from locking themselves back onto her nephew's muscular body, she realized that there was something unusual going on with her. The same might have been happening with the others as well, but as Sean was the only one there except her and they were all checking out her body pretty much constantly every day anyway, this hypothesis of hers would be pretty hard to test at the moment.

There was something weird going on, and she could feel it.

But then, it was also true that her life hadn't been all that normal, or even just generally "non-weird", for years by now.

Not since she, almost a decade ago when she was just 18, got her first role in a mainstream movie. Non-speaking roles usually don't turn newcomers into superstars overnight, but when that role is also nude, and you have the body to absolutely shine in it, as she did, things can get very crazy, very quickly.

Not a day had gone by since that fateful moment, when her massive, pale tits graced millions of TV screens around the world, that someone had not recognized her on the street. Or took a photo of her without her permission. Or tried to hook up with her, not caring what she was doing at the moment.

Usually, the same person was doing all of those things at once. And most of the time, she had to deal with multiple such people a day.

With those, she could deal with.

But when a few of them tried to break into her house, that was where she drew the line.

After years of putting up with stuff like that, she decided that she had had enough. A year ago, having said their goodbyes to their parents, who weren't willing to leave the house where they had lived for so long no matter what harassment they faced in there, she and her 3 brothers, Shawn, Jeffrey, and Thomas, along with Shawn's 2 sons, Sean and Henry, packed their bags and moved to the most remote locality that they could find.

They immediately knew that they had made the right choice.

The scenery was beautiful, the few families living there were incredibly kind to them and, even though they undoubtedly knew who she was, not a single person in here had ever acted like an obsessed fan towards her.

Though... that didn't mean that she didn't receive some slightly unwanted attention in here.

Whether they were her fans or not, the people around her were bound to notice that she was a gorgeous, unbelievably busty, and curvy redhead, and were bound to act on it.

The men, thankfully, usually acted quite cute and clumsy in her presence, rather than creepy, though the women seemed a bit intimidated by her in general. They weren't mean to her, but could be quite cold in her presence. Especially so if she was dealing with a woman whose husband was the guy currently trying to get the attention of the town's version of Christina Hendricks.

But whatever was happening beyond the walls of their new home, it was nothing compared to what was happening between them.

Family or not, her brothers and nephews were still young and healthy heterosexual men, who were now living in a highly secluded area with a world-class bombshell, with few things to do beyond staring at and fantasizing about her. They've all almost completely acclimatized to their new environment by now, but still, some weird tension in the air remained.

And it was all she could feel as she stared silently at her nephew.

"You gonna sit here, or are you just trying to ignore me," she told him, in a rather annoyed tone, as he stood silently, almost unmoving, by the sink. "Or are you preparing to take apart the sink?"

"I'm pretty sure it was leaking yesterday," he replied as he turned towards her, his eyes immediately locking themselves on her half-revealed breasts. "Seems like it's OK now. Guess someone fixed it already. Just wanted to check it out," he said, as he sat next to her.

Not even a few moments after he did so, the door to the kitchen shot open.

"Seems like someone's talking about me here," they heard a familiar, almost-baritone voice say from the direction of the rapidly opened door.

As the well-built, buff, half-naked figure of her eldest brother, Shawn, waltzed into the kitchen and sat by the edge of the table a few seats from her, Marilyn's hungry eyes locked themselves on him just as they did on his son a few moments before.

With just something over a month separating him from his 40

th

birthday, he was more than 10 years older than her or their 2 brothers and was always something of a secondary father figure to his siblings as a result of that. This was especially true whenever their parents' not-always-ideal relationship hit a low point.

Because of that, the fact that he was also a primary father figure to his sons who were both just a couple of years younger than her was still a little weird to her, even though she knew them pretty much since they were born. Not to mention that the fact that he and his girlfriend were already expecting children by 19 was quite annoying to her, as she only lost her virginity a few years ago at 23, a downright unreal age to do so for a woman with her curves.

It wasn't hard to see why he was more sexually successful than her however, as her eyes proved by shamelessly gorging themselves on the eye candy which his half-naked form provided for them. If the beautifully sculpted, well-built buff figure with perfectly defined muscles was a glimpse into what Sean could expect to have as he grew older, then the young man had

nothing

to complain about.

"Been sunbathing or what?" she asked him.

"Nah, why?" he replied, her eyes finally leaving his body after meeting the gaze of his ones.

"I mean, since you're in those boxers," she said, starting to blush as her mouth suddenly dried and her voice almost broke. "And only those boxers."

"Nah, I've been looking at the fence," he replied, sounding rather proud of himself. "I'll probably fix it the next weekend, don't have enough time for that until then."

Suddenly, she felt painfully thirsty. "I need a drink," she said, the dry tone in her voice making her words rather redundant, as she stood up and hurriedly left the kitchen, waltzing into the bathroom.

"Thought so!" her brother yelled out at her in a deadpan tone of voice, as she turned the sink in the bathroom on.

"You know where Henry and the others are!?" she replied, asking as she started drinking the water flowing from the faucet.

"That's actually what I wanted to tell you," he replied, obviously having remembered this fact only because she brought the topic up. "I phoned them when I was out. They just went to buy some groceries and should be here at any moment, they said they were about two blocks away before I came back."

"Uh-hum!" she replied, continuing to gorge on the flowing water for a few moments before loudly closing the door to the bathroom. Splashing the almost ice-cold water on her face a few times in rapid succession, she murmured under her breath some random, unintelligible words which she herself didn't understand, before taking a long, hard look at herself in the bathroom's mirror.

Something was happening to her, something quite serious. Since she had woken up barely an hour ago, she did nothing except dressing up, walking around the house a little, and talking with her brother and nephew, and yet, she felt as if she had run a marathon. Her heart was beating so madly she felt as if her ribcage was going to break to pieces. Her boiling blood felt like it was spilling from her veins. She felt that she was losing control of her body. Her whole body was shaking and jerking, only mildly so far, but it was obvious that it was going to escalate.

She was horny. Incredibly so. This sensation wasn't entirely unknown to her, and though she had, so far, felt it only a few times in her life, she remembered every single instance of it with unparalleled lucidity. This was what she had felt the few times when she got lucky enough to be put into situations that satisfied all of her fetishes, and when her inhibitions broke down enough for her to fully seize the lucky opportunities.

The times when she dared to break through her comfort zone and go down the internet hole to search for videos and stories featuring a, to a normal person, sickening amounts of incest, forced sex, group sex, humiliation, and general degradation, and various combinations thereof. Scenarios which she had fantasized about for years, and which she was grateful that the people who could write better than her chose to do so, producing those stories.

Or the times when, after partnering with a sufficiently open-minded boy-of-the-week, she forcibly pushed herself out of her comfort zone and exploited the opportunity granted to her by realizing her most depraved fantasies, if only in the form of roleplay. On those occasions, of which there were unfortunately only 2 instances, she spent hours in sexual bliss as she was surrounded by half-a-dozen attractive men, treated as nothing more than a cheap whore and a cum receptacle by them, degraded and fucked like she always fantasized about being.

Yes, just as she always fantasized about it, always wanted it to be like. Although this had happened only 2 times in her life so far, she found herself replaying both of those experiences hundreds of times in her head, looking back to them, excitedly waiting for another one of them.

A wait which the light, pleasant tingling in her moistening pussy told her as she heard the excited voices of her relatives greeting themselves, might just have come to an end.

The mere thought of something like that sent her blood boiling ever hotter than it had been so far. She quickly wiped herself dry and clean, the jerky movements of her excited hands roughing the skin on her face a little with the rough blanket, and waltzed out of the bathroom, her curvy hips swaying seductively with each step, to join the rest of her family by the kitchen table.

"Ahhh, here comes the star!" her youngest brother, Thomas, exclaimed the moment he saw her. "Watch out with those hips."

"Why?" she asked, a little-too-sensual smile on her face.

"This ain't a catwalk, you might get cut or something, this is a kitchen after all," he replied.

"Awww, and you'd just love to see me on a catwalk again, wouldn't you?" she asked as she shook her hips again, her smile morphing into a grin as she noticed the hardening erection in his, and the others', pants.

Holding the increasingly smug-looking grin on her face, she began erotically swaying her hips and shaking her half-covered breasts while continuing to watch the budding erections in the pants of the men around her, as if she forgot for a few moments that the hardening cocks belonged to her brothers and nephews.

Yes, her brothers and nephews. Her beloved relatives of the other gender, most of whom she grew up with, and whom she always loved to tease a little with her increasingly attractive body. Something which, now, she was enjoying more than ever before. With their eyes locked on her voluptuous curves, and their hardening cocks straining against the fabrics of their underwear and jeans as her slight teasing gradually evolved into a full-on erotic show, an almost euphoric feeling washed over her. A relieved sense of finality immediately followed.

This was it. This was why she felt so weird today, she knew that this was coming. This was the finish line her life was going towards for the last few months. All the sneaky glances, all the dirty jokes, all the "accidental" touching, all of it was pushing their family towards this moment.

"Erm, Sis," Thomas spoke, rather unsure of himself. "Don't you think you are overdoing it a little?" he added, trying to sound offended, even concerned for her, but the arousal gripping his voice made his real feelings clear.

"Nope," she said, the grin on her face turning suggestively toothy. "

This

is overdoing it!" she exclaimed, as she let her bathrobe fall to the floor, freeing her gorgeously curvy body and exposing her mammoth tits right to her youngest brother's hungry gaze.

Total silence overtook the room as the men's gazes examined the God's gift standing in front of them. As she felt their prying eyes scan every inch of her naked body, their gazes so intense her skin felt like it was burning, a moan escaped from her lips as her rapidly moistening pussy twitched at the scene.

There was no coming back.

"Getting ready to see me overdo it?" she asked, looking into Thomas' dumbstruck face, which was only turning more so as his mind started to understand what she had just said.

"Erm, Sis," he stammered. "You mean?"

She said nothing as she lounged at him. Like a predator who finally got the courage to take her prey, her beautiful body was all over him in moments, locking his body to itself in a tight embrace. The only answers his question got were deep, forceful kisses he received as her lips locked themselves onto his, and her tongue invaded his mouth.

A moan of pleasure vibrated from her mouth down his throat as her blood started to boil again, her heart beating like crazy and her moist pussy twitching and as lust completely overwhelmed her. She was incredibly aroused, more than she had ever been. For a moment, everything that existed to her was just she and her cute younger brother.

Yes, Thomas was quite cute. She always thought so. Big, expressive blue eyes, heart-shaped face with soft features, and kissable lips she was now enjoying to the fullest. He was miles away from his masculine brothers and nephews, but no less attractive because of it. Of course, at just 22, he still had some time to mature, but for now, his pretty-boy features were here to stay.

"Marilyn," he said as he managed to free his mouth from her oral grasp, looking into her eyes while speaking with an awestruck tone of voice she had never heard from him before.

"Thomas," she replied, as the dumbstruck look which returned onto his face alerted her to the fact that he had no idea of what he wanted to say to her.

Before they could realize how awkward this situation was, a realization which would probably be followed by Thomas mumbling and blabbering out something apologetic, the sounds of various pieces of fabric hitting the floor reminded them of the fact that they weren't the only ones in the room.

And they surely weren't the only ones who wanted to have some fun.

As they surveyed the multiple naked masculine bodies around them, she with a slightly awed expression on her face and he with a slightly worried and emasculated one, time itself seemed to have stopped.

To their left was their brother Jeffrey with their nephew, Henry. A year older than her, Jeffrey was the second oldest person in the house, while the 19-year-old Henry was the youngest. Although not brothers, they could've easily passed for a pair of them, and she was surprised to see how similar their bodies looked when there were no clothes to hide them.

The first thing she noticed on Jeffrey, and the first thing which she was sure every woman who ever saw him naked noticed on him, was what was between his legs. She always knew that her older brother was quite gifted in this area. It was impossible not to know if you lived with him since there wasn't much he could do to hide something like THAT for a long time.

Quite simply, her older brother had a massive dick. Where she lucked out in the area women wish they would, he lucked out in the one area just about every man wishes he did. And the rest of his body wasn't bad either. Although nowhere near as muscular as their bodybuilder-resembling older brother, he was still nicely built and rather ripped. In addition to a nice athletic body, he also had a traditionally attractive face, with masculine features, green eyes, and sandy-blond hair, making him one of the 2 blonds, along with Sean, in a family of brunettes and one redhead.
