Desc: Romantic Sex Story: Chapter 1 - Cassie von Greiner can't hide her love affair with her twin brother Hector any longer. Thankfully, in the von Greiner clan, it isn't really a secret and it has the full blessing of her folks. These twins are a bit different from the rest of the tribe, due to their jealousy and absolute fidelity to each other, but they still know how to get very steamy both in and out of bed.

Vicki had been around long enough by now to recognize that look in her daughter's eyes. Cassandra Anne von Greiner, better known as simply Cassie, had a lot on her mind, and her mother had a damn good idea what it was. It was Hector, her twin brother. It had to be Hector, who else?

"Cassie, sweetie, what's wrong?" Vicki asked her as they made breakfast for the family one Saturday morning.

Cassie swallowed a bit, then grabbed some water for a second, before she felt comfortable admitting how she felt.

"Okay, Mom, here it is. I've fallen in love with Hector. I want to be his wife, to grow old with him, to make love to him, all of that stuff. I know that the laws have changed a bit to allow incest, but will you support us? Will Dad and the others accept it, really? We've hinted around at this and discussed it in the abstract, but this is now on the verge of happening soon. Is it really going to be okay with you guys, as much as it denies so much pleasure to the rest of the family? You see, I haven't changed my mind about fidelity. Nothing against you guys, but it's not for me, the sharing and such. I'm far too jealous for that," Cassie finally confessed to her mother, hoping that she would take it well.

"Well, how does Hector feel about this, dear? I imagine that he should have a say in the matter, too," Vicki inquired, wanting to make sure that her kids were happy with their lives.

As unconventional as their family was, there was room for someone with more traditional ideas about sex and love. Twins were a logical enough exception, after all, given their inherent bond. Besides, Bridget already proved that not everyone in the family was cut out for swinging and bisexuality, though she certainly had her own wild ideas, mostly tied to lesbian bondage.

"Mom, Hector and I have already talked about it a good deal. We've both agreed that neither of us can handle sharing each other with anyone else. We're both far too jealous to accept that," Cassie explained to Vicki.

Vicki thought about that for a second and realized something else. The pair seemed to be almost obsessively attached to each other. The parents had suspected something along these lines for some time now, but to have it confirmed was a relief and an end to the suspense. Hector spent more time in Cassie's bedroom than his own, and had often not returned to it until the morning, leading them to suspect that they shared a bed, not that either of them disapproved. They certainly didn't snoop or make any attempts to block such a relationship. If Hector and Cassie wanted to be lovers, that was perfectly fine with their parents.

"Well, I will talk to your father, and to Aunt Haley and Aunt Michelle. We can sit down with you and Hector soon and discuss how to reorganize things. However, for now, tell me, did you two want to share a room sooner rather than later?" Vicki asked her daughter after hugging her.

"Yes, Mom. I'm pretty sure that Hector and I badly want to share a bed at night, and everything else that comes with sharing a bedroom. I'll tell Hector what you said and hear what he says, but he's made it clear so far that he wants to openly take me as a lover. His words, that part, not mine. He's even indicated that he wants to make it official," Cassie thanked her mother for being so kind and helpful about it.

"Have you two made love yet?" Vicki wondered, not that she would have minded either answer. She was just curious by now.

"Yes, Mom. It's the twenty-first century. We've been sexually active. Don't worry, I'm on the pill. I was sixteen when we first made love. We experimented some time before that, too. I don't have a basis for comparison, but he has never failed to satisfy me in that or any other way," Cassie blushed a bit as she answered her mother's query.

"Well, sweetie, he got that honestly, I can tell you. The apple doesn't fall far from the tree there. I'm happy for you, both of you, if you're truly in love and that confident in each other. I'm sure that your father and my sister-wives feel the same about it. We just want to see you happy with your lives. Not everyone is into our scene, and we can all respect that. We can't make you emulate us, just as others couldn't make us follow them. I'll see how quickly we can sit down and have a meeting like I said. Well, one thing is sure. I know that I'll like my son-in-law," Vicki smiled and gave Cassie a butterfly kiss.

"Thank you, Mom. I didn't think that you'd judge us, but I had some anxiety about telling my own mother about my serious feelings for my own twin. It's not something that is brought up every day in the kitchen while making breakfast," Cassie thanked her mother.

Vicki gave her a surprised look and laughed.

"Okay, with this family, maybe it is normal," Cassie giggled as she agreed with her mother's point.

"Yeah, I was about to say," Vicki snickered in response, thinking of the many times she had fucked most of the others in their household. She couldn't help but lick her lips at those memories.

"Anyway, where is Hector? I rarely lose track of where he is at any given moment, you know," Cassie changed the topic quickly; not wishing to think of her mother's many adventures. It wasn't that she was a prude; just that she wasn't into the family's lifestyle.

"Well, that is a shock from you guys! You're practically joined at the hip. I think that it's sweet, actually. You two make such a cute couple. He even took you to the prom, as I can recall. I bet that your secret was out at that point, at least for your high school class," Vicki teased her daughter a little.

"Oh, Mom, do you have to use the C word?" Cassie complained at her mother's description of Hector and her as "cute".

"What's wrong with being cute? I'm your mother. I tend to like seeing you kids get along so well. It's very charming in a way. We've not exactly been surprised at how close you guys really are. The signs were always there, dear. We just thought that it was your business and you'd tell us in your own time. It seems that we were right. Now you don't have to pretend at all.

"That's good, because life is far too short to hide from yourself. Daddy and Uncle Earl were examples of that. They had too little time on this planet, so I'm glad that they were able to be themselves toward the end. I miss both of them and not all of Daddy's or Uncle Earl's surprising hoard of money can ever replace them," Vicki found herself suddenly getting misty as she remembered her father and his partner.

Her love for her dad was unaffected by the news that he was gay. The man had raised her well, and she was never a prude, anyway. Once she got to know Uncle Earl, too, that love spilled over to include him as well. Suddenly, she shook herself to remember the present, not the past, and to think of her daughter's need for her mother's blessing and support.

"Thank you, Mom. I'll try not to let it bother me too much, but I just don't want to be thought of as a little baby. You don't think of the others as that, after all," Cassie explained, hugging her mother to reassure her that she didn't mean to be unkind.

"Yeah, I know, sweetie. However, you are the baby of the family, even if only by an hour. After you were born, I had my tubes cut and tied. I wanted y'all to be my last kids, my babies. I have to admit that we tended to spoil you a little more, just because you were the youngest. Even the elder kids pampered you a bit for that reason, especially Trevor since he was so much older.

"That's why it was so much easier to accept your special relationship and not think of you in sexual terms. I'm not trying to patronize you, honey, just explain to you how we have been a bit protective of you and why that was the case. It's why the words 'cute' and 'adorable' seem to fit you better, and why it is harder not to use them about you, dear," Vicki assured her daughter, as she handed her the last breakfast plate.

"Should I call the others to breakfast?" Cassie offered, dreading the idea of seeing more sex, but wanting to be helpful.

"Get your brother. I'll find the rest. I don't want to expose you to things that might ruin your appetite, even if you've stumbled on them now and then. I know for a fact that you refused to eat on New Years' Eve when you found Michelle in the middle of a DP from your father and me. I think that it was the strap-on part of the action, but I could be wrong. Don't answer that. Forget that I mentioned it, in fact. Just let me call the rest of them, so you can better enjoy your breakfast, baby. You focus on your favorite brother, okay?" Vicki grinned at Cassie in a way that suggested that she thought it was cute how her daughter was squeamish at times about sex toys, evidently preferring only the natural equipment.

"Thank you, Mom. You always seem to know how to make me laugh," Cassie chuckled in spite of her attempts to sound shocked. Somehow, one could never stay annoyed or frustrated with her mother for long. She was too damn funny and sweet for that.

"Well, I like to have fun, you know. Let's go get 'em, huh?" Vicki led Cassie up the stairs, where they went their separate ways, the daughter seeking Hector and Vicki everyone else.

What Vicki didn't say was that she understood that Cassie might end up wanting to make out or a get little frisky with her brother. That could take some time, which was another reason why Hector was the only assignment given to the youngest von Greiner. It was an implied blessing for any kind of fun that the twins might have in mind with each other. After all, the entire family completely approved of the twins' passion for each other, as inconvenient as it might be for them. The important thing was for Cassie and Hector to live their own lives and be happy, not try to conform to others. If Cassie had any worries over the possible reaction to Hector and her confirming their desire for an exclusive relationship, they already started to fade, thanks in a significant way to Vicki's open, if playful, response.

Cassie wasn't a bit surprised to find Hector in her room, fixing her entertainment system as only he could do. Where he got those skills, no one knew, since he was definitely Dan's son. Whatever her father's strengths, electronic gadgetry wasn't one of them. He was a self-described novice when it came to such things. Maybe it was from someone else in their family, or just a fluke entirely of Hector's own. It didn't matter too much, since right then it made Hector his sister's hero, adding to her increasing passion for her brother.

"Thank you, bro. See that only makes me love you more. What a sweet thing to do! I knew that you wouldn't let me down. By the way, breakfast is ready, and I told Mom how I feel about you. She's fine with it, and I think that Dad and the others will be as well. You and I will get to share a bed pretty soon, I expect. The only question is which bed will it be? This one or yours?" Cassie thanked her twin with a deep soul kiss.

"You mean the one that I never use? Forget that business! It can be a spare bed for guests. I want to share this bed with you, the one where we've gotten it on like bunnies for a good while back now. If Mom, Dad, and the ladies are really okay with this, I don't see a reason to hide anything, do you? I mean, we can kiss like that and even feel each other up in front of them, right? We can snuggle up on the sofa on movie nights and make love in the shower, too," Hector observed, liking the idea of openly dating his sister very much. It would simplify things so much on so many levels.

Cassie naturally shared the sentiment and desired to see it happen very soon. They had certainly been intimate before, but this business of being less careful would be a welcome change for them. Speaking of caution, she remembered suddenly to take her pill as always. The last thing that either of them needed was for her to have their future children ahead of schedule, right? There would be a time for that, of course.

"Well, you know that I'm eager to have you anytime I can. I can't turn you down. Well, technically, I can, but why would I want to, honey? I just took my pill and it's time to eat, however, so it will have to wait that long, at least. Besides, for what I have in mind, you'll need the extra calories. You'll certainly burn them off today, babe," Cassie teased her brother, as she wrapped her arms around him and he fondled her delightful buns. She found herself returning the favor, as Hector's tight ass was always something that she enjoyed.

"Well, I am kind of hungry, too. Let's hurry downstairs and eat," Hector led his sister down the stairway, each of them caressing the other's waist.

By that point, everyone else gathered at the table and made sure to leave two places for Cassie and Hector, who always sat together. This enabled Cassie to do little things like play footsie with her brother, not to mention kiss him and lightly stroke his cock through his boxers. Since he was shirtless, she also pressed her side to his as much as she could, not being very subtle in how she teased him. Her tank top and short shorts didn't exactly leave much to the imagination, either. Hector enjoyed the view of her cleavage in particular.

Dan nearly spat out his orange juice as he watched his younger twins feel each other up. He also realized from Hector's embarrassed expression that the young man had a hard-core boner. The patriarch of the Von Greiner clan smiled at his horny offspring and leaned over to whisper something to his first wife, their mother. She whispered back and giggled as she noticed how red Hector was in the face. Then she winked at the twins and wrote a note that she slipped next to the butter on its dish and handed to her third son for his eyes only.

"Go for it, sweetie. She wants you in the worst way. Make us proud. Just be good to our baby girl and don't hurt her. I can tell it's the real thing, son, as can your father," the note read, making Hector blush even more, especially once Cassie snatched it out of his hand and read it as well.

Cassie turned a shade of scarlet, laughed, cried a little, and wrote back on the note, "Thanks, Mom. Trust me, he'll make me very happy. He's from you and Dad, so he's perfect for me. Don't worry, I'll make sure he's happy, too."

Vicki beamed and whispered to Dan, who grinned from ear to ear. By now, the other wives were extremely curious about what was going on, so Haley cleared her throat between bites of her steak and Michelle looked up from her enthusiastic consumption of the hash browns with her lovely dark eyes to pose a wordless query. Dan nodded to Vicki, who showed both sides of the note to the two "aunts". Haley, who sat across Cassie, gave her a high five, while Michelle, next to her, did the "thumbs up" sign.

"Okay, what gives? Is this an inside joke or something? We older kids want to know what's going on, too. All we know is that you're all passing notes and sending signals to each other instead of speaking up. Is there something we should all know about?" Bridget blurted out what the younger Von Greiners thought at this point.

"Well, there are some things not for tender ears, dear. Have you forgotten the little ones in our midst?" Haley reminded her daughter of little Claudia and Danielle Marsh, identical twins that Trevor and Jamie had together, who were only toddlers and therefore not ready for talk of such mature matters.

"Oh, yeah, sorry, Mom. Diane, baby, next time I start to put my foot in my mouth, pinch me somewhere that will get my attention," Bridget asked her wife/slave, who was pregnant with Karl's little donation, just as she was with Trevor's.

That had been one of the few exceptions to the monogamous lesbianism that had marked their lives together, as Bridget felt that the donors deserved a little booty as an expression of the couple's gratitude toward the brothers. As if to reinforce their gay orientation, however, the duo had also slept that week with Natalie, Kirsten, Jamie, and the moms. They even fucked Dan as a back-up plan, not to mention to avoid leaving him as the odd man out.

"Bridget, darling, as much as I'd love to pinch your sweet ass, we both know what price I'd have to pay for doing that. Are you saying that I won't be punished for pinching in those cases?" Diane asked her wife/Mistress playfully, thankful that the rituals of their D/s lifestyle had relaxed a bit of late, for whatever reason.

"Oh, you'll take your punishment like a big girl, and what's more, you'll love every second of it. We both know that much. You're a natural sub, one of the things that I love about you," Bridget teased her slave.

Cassie gagged a bit, making Hector laugh and distract her by squeezing her butt through her shorts. He didn't want her disgusted by the whole lesbian activity in front of them. She reacted to his payback by squirming a bit, but when he started to pull his hand away, she leaned back to trap it in place. After a short moment, however, she let go of it, so he could keep cutting up his steak.

"Just because I squirmed didn't mean that I disliked it, honey. I love it when you squeeze my bottom," Cassie encouraged her twin with a saucy gleam in her eyes.

"You two are something else," Karl grinned at his siblings, laughing at their naughty games during breakfast. The younger twins were unable to keep their hands off each other and it amused him as much as it aroused him.

A wink and a smile from his own twin, Kirsten, indicated that she shared his delight in the antics of the most junior von Greiners. Trevor, Natalie, and Jamie looked at them and then the parents before snickering. They weren't making fun of Cassie and Hector, just enjoying the bawdy atmosphere caused by the lovely young couple.

"Well, what something is that, big brother? Tell us what when you're sure," Cassie paid Karl back for his teasing.

Hector laughed out loud and kissed Cassie in appreciation of her excellent comeback. Karl and the others burst into laughter again, none of them harboring ill will over the response. It was just the kind of retort that he was used to with the other women of the family, playful and light on actual mockery. The only difference was that Cassie wouldn't use such banter to flirt with him. It was more of a typical sisterly taunt with her, albeit with the same delightful wit and gaiety that she inherited from Vicki.

Things quieted down as Dan pointed to his empty plate, indicating that he had finished his food while the others spoke. Cassie and everyone else took the fatherly hint, seasoned as it was by mirth, and put away their steak, eggs, hash browns (in Hector's case, smothered in ketchup), biscuits, and country sausage gravy like it was going out of style. Cassie just hoped that he never got any dirty ideas for the ketchup, of course. Ketchup was revolting and her pussy (or so Hector claimed) was yummy enough on its own. She certainly didn't want to kiss him after that if he did.

Speaking of kisses, Cassie planted a really serious French kiss on Hector as soon as the breakfast was over, while her hands explored his buns. She stopped just long enough to look at her mother with pleading eyes to be excused from cleaning the dishes and clearing the table. Vicki laughed and nodded her whole-hearted blessing, winking at the twins as if she had something to gain by it as well. It was some kind of delicious conspiracy on the mother's part for sure, and the daughter was more than willing to play along, especially as it suited her ends. She was confident (whether fortunately or otherwise) that she would hear all about it later.

"Come on, dear. I want to make sweet love to my sexy brother. Care to try out a new position I've just learned about? I think that you'll like it," Cassie didn't have to ask her twin twice.

"Alright, sis. You got me. Show mercy, though," he joked a surrender to her whims.

"Hey, I have a lot of love for you, babe, but mercy ain't my thing. I'm gonna wear you out and then bask in the glory of our hot, naked bodies as we spoon and rest up for more steamy sex. I want today to be about lots of lovin'," Cassie warned him and she wasn't kidding.

"Well, when you put it that way," Hector took over and almost dragged Cassie to the staircase, where he lifted her up and put her over his shoulders like a caveman.

"Men!" Cassie feigned a gripe, laughing as she squirmed again and smacked his bare back in faux resistance, "I can walk up the stairs by myself, you know!"

"So what? Me Hector, you Cassie," he continued the "Tarzan" charade, making her giggle with amusement and lust. She had to admit to herself that his Neanderthal impression was kinda hot. What girl didn't want to just be taken now and then?

Once the door was closed, Cassie showed her aggression again by yanking down Hector's shorts and sucking eagerly at his dick and balls. She was already wet as it was, but sucking her brother's hard cock caused her pussy to leak its cum down to her ankles, even as it threatened to make him spew a hot load down her throat. Since she didn't want to spoil her plans, the lusty redhead backed off and invited him with her hands to remove her own clothes.

"Thank you, sis. That was awesome!" Hector groaned in his increasingly aroused state.

"Hey, baby, I'm not done with you at all. You haven't even cum yet. Pin me to the wall and fuck me standing up!" Cassie urged him, her lust evident in her baby blue eyes. They were her mother's eyes, full of playfulness and sensuality.

Hector couldn't resist such a splendid offer, and he had no intention of doing so. He did exactly as his sister wanted; impaling her against the thick wall of her bedroom, proving that he was helpless against her wiles, yet very much a man even so. Cassie's legs wrapped around her brother's back as he pounded her from below, bruises and scrapes striking her flesh now and then as her brother invaded her sweet pussy. If she fell and broke her neck afterward, it would still be worthwhile from her perspective, as long as she had her virile brother inside her. She couldn't get enough of Hector at all. She was as addicted to him as he was to her.

Naturally, Hector put his hands on Cassie's hips to direct her thrusts upon his cock, her movements going up and down as he guided her. He could tell just how hungry his twin sister was for him to ravage her, her expressive eyes now glassy with satisfaction as she took him into her body again and again. Neither of them kept track of time, space, noise, discomfort, or physical exertion. All that they cared about was mating with each other in this new arrangement, which both could tell would soon be one of their favorites. They adored the sheer primal quality of it, the instinctive drive to have each other overwhelming them as they enjoyed each others' bodies and obvious passion for each other.

Hector couldn't have imagined how fantastic it felt to go so far inside Cassie as he did now. It was a truly magnificent thing, to be so deeply plunged into his sister's pussy, now dangerously close to her womb. His stiff cock gave her no relief or respite, as he plowed her fantastically warm cunt until she shivered and burst out her juices like a broken fire hydrant. Her slippery hole was now even easier to fuck than before, and he soon felt as if he couldn't tell where he ended and Cassie began anymore.

She wasn't lukewarm between her thighs now. She was as hot as an active volcano as he drilled her for their mutual pleasure. She was sticky and slick as he continued to slam her forcefully with his uncut cock. She had him completely inside her, her body engulfing him like a huge chasm that just sucked him into her depths. Hector felt nearly swallowed up by Cassie, as he continued to take her for what seemed like an eternity of sex that made him feel deliciously trapped by her wet pussy and its deepest, darkest parts. He didn't mind or care at all by this point. He was just lost inside the cavernous Cassie, who apparently refused to quit until she was good and ready.

To Cassie, enveloping her brother was the most satisfying, delectable sensation conceivable to her adolescent mind. Eventually, in fact, the brain had nothing to do with it. She wasn't capable of reasoning anymore. She was as much a captive as the young man whom she loved, the boy whose aggressive cock plundered the deep treasures of her cunt. She was a prisoner of her ardor for her delicious brother, the man she wouldn't give up for anything in existence. She might be encircling him, but he had her pressed to the wall, mindlessly reeling from the juggernaut of pleasure that he gave her.

Cassie didn't know what it was like to be fucked by another man and this was another example of why. How could anyone else ever give her such bliss? She didn't care to chance the likely disappointment. She was like a fine musical instrument and he the master who knew best how to play it. As much as she loved her father and older brothers, this act and this body belonged solely to the youth who now used her for their shared gratification. She neither knew nor cared for anything or anyone else when it came to sex. She was his and he was hers. Their bodies were the private property of each other and that wouldn't change as long as both of them drew a breath.

Alas, all good things must indeed cum to an end, as the saying goes, and this was no less for the twins. Their bodies both shook with an unexpected and unprecedented experience of mutual climax, Cassie quivering as her orgasm and her hip movements collided with Hector's hot seed shooting into the farthest part of her now stretched and ransacked pussy.

She felt the most explosive chain reaction as her taut muscles clenched his soaked dick in the middle of his penetration of her heated pussy. This forced him to expel the last spurts of his cum just outside of her womb. It was almost a shame that she was on the pill, since part of her craved the chance to conceive their firstborn child just then. Then again, Cassie reminded herself, there would be plenty of opportunities to do just that, including in this position. They had many years yet in which to have their way with each other, both romantically and sexually. They were still young and time was very much their friend.

When the twins relaxed and could think sensibly again, Hector helped Cassie balance herself on her feet again, so they could walk safely to the bed for some splendid spooning. This was as much a pleasure for Hector as for Cassie, since few things aside from sex itself were as sensual and erotic as the contact of his skin on hers while they lay in bed to spoon. Thoroughly drained, both of the twins easily and happily dozed back into a lengthy siesta, from which they were sure to awaken in this wonderful position.

Knowing each other as well as they did, the mere brushing of Hector's cock against Cassie's ass, soft as silk in their touch to each other, would be more than enough to rouse their fiercest, most passionate drives of all. Then again, that was hardly a reason to complain, as both would sincerely and earnestly agree. On the contrary, it was a damn good way to wake up from a long and invigorating nap. No doubt there was far more to anticipate than that, of course, but that was an excellent way to begin the day. Nothing short of the end of the world could ruin a day that began like this.

It was a glorious day indeed for the twins, a triumph over fear and a victory for true love, tempered only by incredible lust. Money couldn't buy them happiness, but they already had plenty of both. Hector and Cassie now reveled in the dreams of the most satisfied people they ever knew. Were it not for what awaited them up in the real world, it would indeed be a pity to wake them up, but thankfully both of them now counted their dreams as cumming true.

It was ten o'clock and all truly was well.
