Chapter 10

“Well, it’s rest stop time. Anyone want to get it on in the bathroom?” Hector asked Cassie and Margie as they stopped at a local service station at last.

“Hell, yeah!” Cassie and Margie said in unison, laughing as they grinned and winked at each other.

Before Hector knew it, he was inside the unisex restroom with both ladies, as they took him inside their throats to the root. This was just to fluff him, to get him nice and excited. It led to him spreading Cassie’s cheeks to rim her for a little while as his twin did the same for Margie. For the moment, at least, all was fun and games between the trio, as long as they didn’t think of the accidental death of Dan and his wives, parents to the twins.

In the back of both Hector’s mind and Cassie’s, though, there was some doubt as to whether they could handle this kind of sharing after being exclusive for so long. Was it just a crazy fluke or could they make it last with three instead of two, given their jealous habits of the past? They were flying blind into a new reality, a new life, and maybe it was too much change at once. More to the point, were they monogamous in the past only because of Dan or was there more to it than that? Was it fair to Margie, or would she always be a third wheel in the world of the twins?

For now, though, they relaxed and enjoyed their threesome. Hector in particular loved the taste of Cassie’s bottom and she didn’t mind how Margie tasted, either. Whatever else happened, poly or mono, the twins knew that they include rimming as a regular feature of their lovin’. It was literally too delicious to avoid it.

Hector soon found his cock buried inside Margie for a couple of strokes, and then Cassie for some more. This kept up, back and forth, something that he had never tried before, of course, since he had always been as faithful to his sister as she had been to him. Once again, this was fun, but he had real doubts and anxiety growing in the back of his mind. What if she decided that she liked pussy more than dick and just wanted to be with a woman? What if she turned out to be gay? He would be crushed by that.

Of course, Margie also felt something ... off about this threesome, as great as it was. She enjoyed it, but it was just ... weird somehow. It felt almost robotic in some ways, not as playful and wrought with feeling as the first time. And then it hit her ... the first time was an innocent act of curiosity as part of a typically monogamous couple’s experimentation. That was why it felt so great, so sensual and fun. This act felt ... stilted ... forced ... as if they were trying to prove something that just wasn’t true.

“Stop!” Margie shouted rather abruptly, shaking up both of the twins.

Hector immediately pulled out of Margie and stared at both her and Cassie.

“Look ... this was a fun little experiment ... a nice little item to scratch off your bucket list, okay, but it’s just ... it’s not right, and all of us know it. I was convinced that it would be great for the three of us, but it just ... it feels like forcing something, like a square peg in the proverbial round hole. We’ve been kidding ourselves ... and you know it. I know it. Cassie knows it, don’t you, Cass?”

Cassie blushed and nodded, in spite of herself.

“Sorry, Hector ... babe ... you know that she’s right. It’s not ... immoral or anything. Don’t get me wrong. There is nothing intrinsically, inherently evil or sinful or wrong about sharing, if that’s what best suits everyone. But it doesn’t, and we all know it. Don’t we, Hector? We’re our own little world, aren’t we, dear? It was a nice treat and trial ... a little game, sure, but we all know the truth. You ... and me ... both of us ... we belong together ... just you and me. One girl, one boy.
