It had started reasonably enough.
Tsuki could grow to the size of a large dog. This was established, documented, demonstrated in training. What had not been anticipated was that Lyra would discover riding a large dog was considerably more efficient than walking, and that she would apply this to every journey inside the house.
The kitchen was thirty feet from Lyra's room. She rode Tsuki there for breakfast. She rode Tsuki back for her book. She rode Tsuki from the kitchen to the main room — twelve feet — because the book was heavy and she was tired. She rode Tsuki to the door, from the door to the step, from the step to the garden gate and back.
Tsuki bore all of this with dignified patience. She moved carefully around corners, ducked under doorframes, and expressed no opinion.
The household expressed opinions.
Clara expressed the opinion that it was funny until Tsuki clipped the side table going around the kitchen corner and the water jug wobbled dangerously. Thomas said once that it was inefficient, which was the harshest thing in his vocabulary. His mother waited.
She waited until Lyra arrived at the breakfast table on Tsukiback on the third consecutive morning, dismounted with practiced ease, and sat down as though nothing unusual had occurred.
'Lyra,' Mira said.
'Good morning, Mom.'
'We are going to talk about a new rule.'
The rule was simple: no mounting an animal indoors. Outside, fine. The yard, absolutely. Inside the house, everyone walked on their own feet.
Lyra accepted this with grace. She was then seen twenty minutes later mounting Tsuki in the doorway — just past the threshold, technically outside — and riding her across the yard to the garden.
The spirit of the rule, it turned out, required a conversation about the letter.

The race had been Clara's idea, which explained why it covered so much ground.
She and Lyra had been building the course over three days: from the barn gate along the east field fence line, down to the creek bank, along the water for a quarter mile, into the outerwood where the trees were wide enough to navigate at speed, then back across the south meadow to the barn. The ribbons marking the turns were Clara's. The creek section had been Lyra's contribution, chosen for the agility it required.
Arthur asked if he could join. Clara said obviously. He asked Saya.
Saya, who had been watching the course-building with suppressed competitive interest, said she would run.
'Run,' Arthur said.
'On foot. Yes.'
'Against people on mounts.'
'Is that a problem?'
He thought about what he knew about fox demihuman enhancement magic and the three hundred years her tribe had put into it. He looked back at her.
'No,' he said. 'That should be fine.'
Thomas, when informed, asked what time it started. Kona was already standing before he finished the sentence.
◆ ◆ ◆
They lined up at the barn gate: Shadow and Arthur, Tsuki and Lyra, Kiiro and Clara, Kona and Thomas, and Saya at the end of the line on her own two feet, bouncing lightly on her heels, her blue tail moving with the slow sweep of something that knew it was about to have a very good time. Magic was prohibited for everyone on mounts. Saya being on her own two feet could use her enhancement spells, naturally.
Clara counted them down.
The first fifty meters were good chaos — everyone discovering at the same moment that everyone else was also going fast. Shadow moved low and smooth. Tsuki flowed forward with the liquid ease of something built for this. Kiiro went wide around the first corner, still calibrating her size, and clipped the ribbon, which Clara yelled about for ten seconds before she was going too fast to yell. Kona ran like a black wave, Thomas flat and grinning in his quiet way.
And Saya ran.
She had activated the Enhancement before the count finished — Arthur caught the spell signature through his passive diagnostic, the elegant layering he had spent an hour admiring the first time she showed him. Under it she didn't run like a person running fast. She ran like something that was very good at this in a way that had nothing to do with effort. The ground happened under her feet and she was already somewhere else.
By the creek bank she was ahead. By the forest stretch she was considerably ahead. She crossed the south meadow finish and turned around and stood there, tail wagging at full enthusiasm, watching everyone else arrive.
Clara came in second, pointed at her immediately.
'That is not fair,' Clara said, in the tone of someone impressed against their will.
'You put me on foot,' Saya said. Her ears were forward and bright. She was not close to breathing hard.
'I thought that would slow you down.'
'I'm a fox,' Saya said simply.
Thomas arrived and said 'hm' in the way that covered most of the relevant ground and patted Kona. Arthur arrived last because Shadow had gotten distracted in the forest stretch and he had let her. His own fault and he knew it.
They ran three more times. Saya won all three. By the fourth race Clara had stopped protesting and started working out the line through the forest that would let Kiiro's size be an advantage, which was the correct response.
After the fourth race everyone was warm and loud and Lyra had grass in her hair and Thomas was grinning in the contained way he grinned when he was genuinely enjoying something.
'Ok everyone time to go cool off in the swimming hole!' Clara announced with excitement.
Nobody argued.
◆ ◆ ◆
Arthur had spent the previous afternoon on the swimsuits.
The swimming hole was a deep bend in the creek a quarter mile past the farm's southern edge, shaded by old willows, with a smooth stone bank and water that ran cold and clear from somewhere further up in the forest. The family had been going there in summer for years. What had not previously been considered was that Saya was now part of the household and that nobody had thought about swimwear until Arthur had thought about it.
He had done it properly.
For Lyra: deep blue, the color she always gravitated toward, with silver stitching at the edges that caught light the way Tsuki's silver streaks did. A small bow at the front of the top, a high-waisted bottom. Elegant and easy, exactly like her.
For Clara: gold. There was no other choice for Clara. A bold cut that matched her personality — the kind of thing that arrived in a room the way Clara arrived in rooms. A thin tie at the hip she could adjust herself, because Clara adjusted things to her preference.
For Saya: pale blue-white, like winter sky, with a clean opening at the back designed specifically for the tail — a finished edge that let it move freely. He had spent longer on this than any other element. Small details along the hem in a pattern that suggested foxfire if you looked closely.
He had been going to stop there.
Then his mother had appeared in the doorway of the workroom, looked at what was on the table, and said, in a particular tone: 'Those are lovely.'
'Thank you.'
'You made three.'
'Yes.'
A pause of exactly the right length.
'Three,' she said again.
He looked at her. He reached back into his spatial pocket for more material. 'Sit down, Mom. What colors do you like?'
◆ ◆ ◆
Mira's was deep coral — the warm red-orange of late summer afternoon — with a ruched top and high-waisted bottoms in a silhouette that was graceful and suited to someone who moved through the world with her particular quality of ease. A thin gold ring at the center of the top. A small drape at the hip.
Later, at the swimming hole, Edric watched his wife come out from behind the changing willow and stand on the bank in the late morning light in the coral swimsuit, and stopped mid-sentence.
He appeared to briefly forget the word he had been reaching for.
'Dad, stop ogling mom!' Clara said.
'Mm,' Edric said. He was still looking at Mira.
Mira looked at him and smiled the smile of someone who had noticed and was graciously pretending she hadn't. Clara having witnessed this entire sequence and laughed for a considerable time.
◆ ◆ ◆
It was Lyra who noticed first and Clara who said it out loud.
They were on the flat stones wringing water from their hair when Clara looked at her swimsuit, then Lyra's, then Saya's, and did the arithmetic.
'These fit perfectly,' Clara said.
'Yes,' Lyra said.
'Not approximately. Perfectly. Mine, yours, Saya's, Mom's.' She turned. 'Arthur.'
He looked up from the rock downstream where he had been reading.
'How do they fit perfectly?'
'I made them to fit.'
'How did you know our sizes?'
A pause.
He set down what he was reading. He looked at Clara. He looked at Lyra, who had the expression of someone who had connected the same dots and was waiting. He looked at Saya, curious. At his mother, who was also now wondering about this.
He stood up and walked toward the willow at the bank's edge, wanting something at his back.
He was not fast enough.
Clara and Lyra reached the willow at the same time he did and arranged themselves between him and the path back, arms folded, wearing the expressions of sisters who had coordinated without speaking. He was against the tree.
'Relax, I used a measurement spell,' he said.
'A measurement spell, hm something is fishy here,' Clara repeated.
'A diagnostic variant. I adapted the body-scan for dimension mapping. It reads surface measurements only, it's perfectly standard magical — '
'You scanned us,' Lyra said.
'For measurements. Only measurements. The scan is instantaneous — '
'When,' Clara said.
'Yesterday morning. At breakfast. It takes no time at all and doesn't — '
'You measured us at breakfast without saying anything,' Lyra said.
'If I had said something you would have made it a whole — ' He stopped. 'It was for the swimsuits. Which you are wearing. Which fit correctly. That was the point.'
The two sisters looked at him.
'It fits very well,' Saya said helpfully, from behind them.
'Thank you, Saya,' Arthur said feeling slightly vindicated.
Another look between sisters. A full conversation in it.
'Next time, say something first,' Lyra said.
'Noted.'
'They're genuinely beautiful,' Clara added. 'That doesn't mean you were right.'
'Also noted.'
They stepped aside. He came back to the bank with the careful pace of someone who had emerged from something roughly intact and was not going to press his luck.
