Chapter Text
Lumine was a third in her romance novel that afternoon when she felt this strange urge come up. The book was good, enough to keep her attention completely so far. Until it suddenly wasn´t. Because the deeper she got into the story, the deeper her mind drew her into this thought that something was missing. She wasn´t sure at all what, which only caused her to become annoyed because why could she not just enjoy her book in peace.
She tried a few more pages before she gave up, suddenly having enough of the asshole of a male lead and the cringy female lead. Carefully placing her bookmarker she stalked to Aethers room, barging into it and then freezing when it’s empty. Of course.
Aether was gone to a friend’s place. Like always. Which was fine, he was the more social one between the two of them. It’s just that she had no plans after arriving in Aethers room but him not being here didn’t feel quite right either.
He was quite protective of his space; he didn’t mind at all when she came in while he was there but if he wasn’t then it was strictly off-limits. But he wasn’t here right now, was he? The itch returned trice as strong and before she knew it she was kneeling down in front of his closet. He kept his comfy sweaters on the bottom of the drawers and that sounded like exactly what she needed.
She put up the sweater on as fast as she could and felt some of that strange urge settle down for a bit. Calmed, she realized how the situation looked like. In her haste to get the right one she had made a total mess and now was surrounded by a mess of Aether’s sweaters. A sense of shame came up and Lumine felt like hiding, crawling into a hole and not coming out until she was ready.
And she did so. But she didn’t go back to her own room, no, hiding felt better and safer when it could be done in Aether’s room, surrounded by clothing that smelled completely like him and his bed, which they had argued felt better like hers anyways.
Mindlessly dragging all the sweaters along with her, she settled deep into his blankets. It was when she moved the pillow that she found her biggest chest of joy yet. Their old plushies. Unexplainable warmth surged within her and she hugged them as close to her chest as she could. With them against her, enough sweaters around her she laid down and let sleep claim her.
The first time it happened Aether had dubbed it as a childish mood that he couldn’t understand. Something about Lumine being a girl and boys like him never being able to understand girls anyways. He had come home from playing at Kazuha’s and honestly needed to recharge for a bit. Lumine should’ve been reading her book on the couch, welcoming him with a side glance and a silent offer for tea so they could keep each other company until their parents returned.
What was unusual that Lumine’s book laid on the coffee table, nowhere near finished and there was no recent scent of her either. He went upstairs only to be surprised once more when the door to her room was left open too. Her scent was noticeable stronger though, so he at least knew she was in the house.
In the end he just returned to his own room which brought the biggest surprise of all night. There she was, lying fast asleep in between everything that was his. Even those plushies he hid from her because he didn’t want her to think of him as childish. Guess that façade was over now too. But after this Lumine would have no right at all to tease him because honestly, what the hell was this.
Both of them were mature for their age at 13 but this was some kind of child play that he really hadn’t expected from her. He got closer and took in the mess that he couldn’t even comprehend because for what reason had she thought that it would be necessary to take out all his clothes and blankets?
She didn’t rouse when he got closer and Aether noticed something odd about her smell. Their secondary sensor skills weren’t developed at all if they had to believe his parents, but even with his underdeveloped smell he could smell that there was something different from usual.
But she looked so peaceful and even though she had invaded all his space, he had no desire to wake her up and scold her. If he had any desire it was to lay down next to her and sleep because he really was tired.
And he gave into that urge after not too much consideration. Even sleeping she adjusted to him, gave him enough room so he could lay down next to her and it didn’t even take five minutes before he was asleep.
Their parents had found them hours later, cuddled up, sleeping in between all thing Aether owned with a room smelling quite heavily of pheromones. They shared a worried look because while this happening wasn’t unusual, it was unusual for her, an omega most likely, to take to one smell already at this age. And for that smell to be owned by her brother was really, really unusual.
It would be time for a talk.
