This was written for gayspiderman on tumblr, with Krexie and the prompt "Giving them your dessert when you eat out because it's their favorite."
This takes place in an au where Krel got left behind in the coup and ended up working for Morando, only to end up in New York City months later, where he meets Douxie and the two of them end up becoming roommates/fake married for monetary purposes, protecting Nari, and so much pining (Archie is suffering at just how badly the two of them are at communicating their romantic feelings to each other).
Krel didn't need to eat. He just survived, no matter what he did or didn't do. But, as he'd found out, if he ate he was a little less consumed by self-hatred. So, he'd eat, but he had a habit of making sure he ate less than Douxie and Archie did, because for all their immortality they had the ability to starve. He knew Nari tried not to eat much, either, but Douxie didn't seem to worry about her as much. It was probably because she was smaller, and didn't exert energy pretending to be human and working a job like Krel did.
Nari wasn't with them right now, and neither was Archie. In fact, when the two of them had realized that their scheduled had managed to sync up in such a way that they'd both have the evening off together for once (the entire evening together, not just the late night together or only one with the evening off), Archie and Nari had told them to take some time together. Just the two of them. They could actually talk, as Archie had said in a long-suffering way.
Krel had no idea what Archie had been talking about. Krel and Douxie talked plenty, often forgoing sleep that Douxie needed to survive and Krel needed to be a kinder person that wanted to live just so that the two of them could talk. More than once, Krel had thought about mentioning that if the two of them were to sleep in the same room, then they could talk even later into the night without one of them eventually having to leave to get at least an hour's sleep. They could just talk until they naturally drifted off to sleep. But then, that would be too close, wouldn't it? It's not like they're married in a way that isn't just forged documents.
Douxie had opted for an adult's meal, which he had finished and was licking the salt off of his fingers. Krel was not watching, because he knew that if he watched the flick of Douxie's tongue too closely then Krel would get caught up imagining a world where Douxie wanted to kiss Krel as badly as Krel wanted to kiss Douxie, and then Krel might end up blushing and someone might notice that Krel's blush was cyan. Even with the power of a god and the mind of someone who had once been a genius (before the coup, anyways, before Krel had made the thousand horrible decisions that had somehow left him to this beautiful, perfect outcome he didn't deserve), Krel couldn't make his transduction have the correct color of blood. That, or Douxie will ask why Krel was blushing, and Krel would have to lie to him because he didn't want to ruin their friendship.
Krel had opted for a kid's meal, because it was smaller and cheaper and Krel didn't actually need to eat. Besides, despite the wording there was no rule that the person eating the meal had to be a child. To Krel's surprise, the meal was not just smaller, but it came with a cookie.
Douxie had a sweet tooth, and so Krel tapped him on the shoulder and gestured to the cookie before asking, "Would you like to have it?"
"Are you sure? It's yours." Douxie said, leaning into Krel's fingertips on his shoulder.
"I wouldn't be asking if I didn't," Krel said, and then, because he knew his husband will worry, "Besides, I'm not hungry."
Douxie was so kind, for still worrying over Krel even when Krel had told him the truth about what he is, and what he's done. And yet, Krel didn't want him to worry. He wanted for Douxie to be happy, forever if it were possible.
Douxie searched Krel's face, and when he didn't find whatever he's looking for (a sign that Krel wanted the cookie, perhaps?) he took the cookie and then bit into it. Krel catalogued the delighted look Douxie had at the taste.
Douxie smiled awkwardly at Krel. "You sure you don't want to share?"
Krel knew that Douxie probably meant breaking it in half, but Krel very quickly finished the last of his water as the thought of biting into the place where Douxie's lips had been flooded Krel's mind. "No, you have it."
