Cassie lost any sense of her surroundings, as usual, while she rode Hector's cock on their bed, the very last morning before she departed for school to claim their room in the co-ed dorms. It was damn near impossible to focus on packing or even the passage of time as they burned off the calories from their hearty breakfast of cheesy scrambled eggs, bacon, sausage, and raspberry pancakes. With this workout, they would certainly have use for the fuel, too.
As typically happened with Cassie when Hector was inside her, her brain seemed to suspend all activities unrelated to incredible, insatiable, and incestuous sex. Nothing but her body's combination with his mattered at all to her at the moment. Everything else could wait until they were good and ready to attend to such things, once Hector and she were done gratifying each other first. For Cassie, Hector came first and vice versa. Nothing else could trump her love and attention to him.
For the twins, there was no question or debate over the issue of soul mates. Cassie was born from the same womb as her soul mate, an hour after he entered the world. Her spirit was bound to his, along with her heart, mind, and will. Her flesh could not help but follow suit. Her life belonged to Hector and his to him.
It was why she hated waking up alone, with him not there next to her. It was the reason that her skin crawled when it went long enough without touching his. They were linked in a way that few brothers and sisters could ever be. When they first noticed the opposite sex, it was by noticing each other. Their first and only lovers' kisses were on each others' lips. It was only normal and natural to them that their first, last, and only coupling would be with each other. They couldn't bed anyone else, making love or otherwise. It was simply unthinkable to them. It was just how it always had been for them, the only way that it could be.
It was also why they dreaded the next month, as Hector fulfilled his responsibilities at his father's firm. Everyone had agreed in principle that he should try to behave like a regular employee as much as possible, so as to learn more about the practical side of the business of editing and publishing, not to mention the importance of office morale. It was a time like this, however, which painfully tested such ideas, since it would force the twins to wait another month to be together again, Hector having given his formal notice to Dad.
Everything else was only a difficult parting for them, but separation from each other was a like a knife in the hearts of brother and sister alike. How could they stand not to fall sleep with each other, having made love to the point of exhaustion before snuggling? How could they cope with not spooning, engaging in pillow talk, and waking up in each others' embrace? How could they handle showering and bathing alone, after so long of washing and drying each other on a daily basis? How could they deal with not comforting each other when sad, scared, or shaken from a nightmare?
In the meantime, the young couple soaked up as much pleasure and satisfaction from each other as they could. They practiced every position they could imagine, but this was one of their favorites, as it allowed them to look into each others' eyes (and gave Hector an eyeful of Cassie's breasts, to be frank). For Cassie, being able to control the pace at which she would slide on his cock helped a great deal in achieving her climax. Another favorite was missionary, but there was time enough for that before tomorrow morning and the much feared separation. For the moment, it was enough to enjoy each other with the time left in the bed they now shared.
Since moving into Cassie's bedroom and making it officially theirs, Hector had felt a lot less anxiety and some nights they had been loud enough in their lovemaking that the rest of the family knew exactly what was going on. This prompted everyone else, especially Dan and Vicki, to grin and wink at them whenever they emerged from the bedroom to shower the next day. More than once, moans of pleasure from the master bedroom indicated that the parents took delight in knowing what their youngest twins did with each other.
In any case, Cassie right now couldn't have thought of anything else if her life depended on it. Her mind was lost to the delicious experience of having Hector go deep inside her pussy from below. He seemed to reach everything, every time in this position, though she naturally had more than a little to do with that. He certainly had long since discovered her G-spot, much to her ecstasy so much of the time. His loving caress on her bottom as she straddled him always felt incredibly sensual to her.
It was no surprise that they were naked a lot in the bedroom together. They got dressed often just barely (pun intended) before they left the room, so that they could stay nude as long as possible. Hector couldn't get enough of Cassie, from her lovely head of ginger hair to her soft, smooth feet. Her skin was so silky and fair, so erotic merely to touch, that he had a hard time accepting that for a whole month, he wouldn't get to kiss it and press his flesh against hers.
Well, he put that out of his mind for now, concentrating on ways to make sure that she lost herself as she so regularly did when he impaled her from beneath. When he saw the glassy look in her baby blues, he knew that he had done his work very well indeed, that he had sent her off to Paradise, at least for a short time. That sense of absolute bliss was what he loved to cause, the kind of rapture in his sister's sweet face as she didn't want to detach her body from his, ever again.
To Cassie, it was impossible to imagine life without this deep carnal, yet spiritual thrill, this oblivious sense of fusion with her brother, her lover, her man. That some laws had contrived to prevent her from formally calling him her mate didn't change what he was to her and she was to him. They were man and wife at heart, and they were truly joined as one. There wasn't a question of when they became a couple: they had always been one, as far as she knew. She fell in love before she knew what lust was, before she was aware of what their bodies could do together.
It didn't matter to either of them where they lived. They would be at home wherever they shared a life, shared a bed, and shared their dreams. Home to Hector and Cassie was the life of being together, the permanent delight of working together, and the future happiness of having and raising children, even growing old together. It wouldn't even occur to them to live apart, except for this brief time which unsettled both of them. Even this short-term separation seemed unnatural and dreadful. Could they even survive it without going mad? That was an open question for both of the twins, to whom each others' company seemed as necessary as the air which they breathed.
The twins had now reached the absolute pinnacle of their ecstasy, the sweet gratification of their flesh and spirit alike. As Hector's cock continued to invade Cassie's pussy, reaching into the deepest parts of her wonderful body, the younger sister couldn't resist her need to spill her juices all over his dick. She was in a trance, unable to think of anything but his hard cock within her, so close to her womb. She splattered her cum on her brother at last, a sensation that made any remaining blood in his body rush immediately to his dick and balls.
The other effect of Cassie's climax was to make her muscles squeeze hard on Hector's cock, increasing the pressure on him to cum as well. He felt his balls tighten up and his load push into his dick to explode from it into his sister's pussy as it always did. This moment brought him once again unparalleled satisfaction, simply not attainable otherwise. It was his absolute favorite thing to do, bar none, to cum inside his sister's sweet pussy yet again. While it left Hector shaky and drained for a minute or two, it was more than worthwhile to give his cum to the only woman who ever deserved it: his sweet Cassie.
"Is it just me, or is that your favorite position, babe?" Hector teased his sister, as they lay on the bed in each others' arms.
"One of them for sure, bro. I like any position that lets me see your face. That's what I really enjoy about making love to you, other than the act itself and our release. It's how much I can see your love in your eyes and your smile, your pleasure as you enter me and merge our bodies into one. Nothing against certain positions for other people, but they're not personal enough for me. Does that make any sense to you?" Cassie answered thoughtfully and candidly, feeling safe again with her twin to explain herself while they unwound from their lovemaking.
"Certainly, because when I see that look of complete bliss in your eyes, I am happier than I could be in any other situation. Your eyes glaze over and you seem to float above the clouds as you ride me. It's utter abandon and you are too far gone at that point to even do anything but live in the moment. That's the best part of making love to you, sis. I love to see your joy when we join together as if a single person, you and I. The next best part is this, lying here completely sated and pleased with each other, knowing that I've just coupled with my sweet sister. That's definitely number two on my list," Hector grinned when he heard his twin's words. They echoed his own sentiments absolutely.
