A well kept secret (private)
 

It was well, bittersweet to say anything. Tsukasa had told her mother something about herself not even Kagami knew. She had confided in her mother that she wanted to wear diapers again. Her mother at first thought something was wrong with Tsukasa, but Tsukasa insisted that she think about it at least. After a lengthy private discussion with her mother, she finally got her mother to agree that she was normal. But this came at a cost, she'd have to make sure no one else found out about this, which could be hard in a household of six. On the brightside though, her mother had agreed to keep her youngest daughter in supply of the diapers she so desperately wanted.

It was just the start of the day when Miki Hiiragi approached Tsukasa's bed quietly, deciding to wake her up before Kagami.

It still felt a little odd to be dealing with her 17-year-old daughter wearing diapers again, especially without Kagami or anyone else knowing, but Miki had put aside her initial reservations about the arrangement; Tsukasa had always needed a little extra care, and being allowed to wear diapers outside of school made her happy. When it came right down to that, Miki was fine with it being a little odd as long as it was what Tsukasa wanted.

Even so, Miki was careful to avoid making Kagami suspicious; Tsukasa's twin hadn't noticed anything odd so far, but she was a much lighter sleeper than Tsukasa and so Miki had to take to waking Tsukasa up personally so she could get dressed before Kagami could notice anything.

Come to think of it, it'd be a lot easier to keep Tsukasa from noticing if Kagami had been the one to start wearing diapers...but then, that's not really Kagami's nature. Miki thought to herself, gently touching Tsukasa's shoulder.

"Good morning, Tsukasa..."

"Mmmnnn...." Tsukasa mumbled as her mother woke her up. "Oh good morning mom~ I didn't expect you to be in here so early. What time is it?" The short-haired girl asked, while slowly wetting her diaper. Thankfully she did have quite a thick diaper on so there wasn't too much of a worry for it leaking.

"It's a little after eight..." Miki said, smiling as she kissed her daughter on the cheek. Sitting down on the bed, Miki pulled back the sheets and checked Tsukasa's diaper. She wasn't very surprised that it was soaked, but she did notice for the most part that was from Tsukasa going just now. Still, she glanced at Tsukasa curiously.

"How are they holding up? Are you comfortable sleeping in them?" She asked.

Tsukasa nodded eagarly at the second question. "They hold up really well and they really do make it easy to go to sleep now. I passed out even quicker than I usually do. I'm not leaking right now am I?" Tsukasa was unsure of whether her diaper was leaking, being in the position she was in. She was also, after only a few days, unable to tell if she was leaking. She could control when she went and could also tell when she was wet still however.

Miki shook her head, poking the diaper.

"But you are quite soaked. These ones are very thick, so there shouldn't be much worry of leaking unless you go more than usual in them." She reassured her daughter, getting a diaper bag out of its hiding place in her room and setting up a pad for Tsukasa to lie down on.

Tsukasa climbed out of bed and laid on the changing mat her mother had just put out. She didn't sleep in her usual pajamas, as she opted for a long nightie instead for easier changes should she need them.

"I'm glad you're here to change diapers mama." Tsukasa said out loud, her face beaming.

Miki smiled at her daughter, lifting up her nightie a little to open up the soaked diaper before rolling it up and disposing of it. Next, she got out some baby wipes, gently starting to clean Tsukasa up.

"I'm glad too, Tsukasa..." She admitted, giving her daughter a little kiss on the forehead. If Tsukasa wanted to wear diapers, all Miki wanted was for her daughter to be happy, but Miki knew she would not like the idea of anyone but herself changing Tsukasa, even if anyone else knew.

Tsukasa let out a small yawn as she was still waking up, and for some reason having her mother change her diapers was something that relaxed her, she often drifted off to sleep at her last diaper change of the day, the one where her mother changed her into her nighttime diapers.

"Momma, what are we gonna do today?" She asked, mainly because it was a Saturday and she and her mother often did something together on Saturdays.

As soon as she finished asking, her mother opened the baby powder and Tsukasa inhaled a small bit of the silky white powder. She loved this scent, ever since she was out of diapers at age 3, then unfortunately put back in diapers full time again at 5 due to an illness.

Miki finished powdering Tsukasa up, taping her new diaper shut snugly around her.

"Well, I thought it might be nice to go to the park together after breakfast..." Miki said, smiling a little. Kagami was growing steadily more independent, and while Tsukasa was often with her twin, Miki was glad that Tsukasa still loved spending their Saturdays together.
