For a moment Mei just looked at Yuzu. She wasn't making any faces or giving Yuzu any looks, she was just thinking hard about what Yuzu had just said. "You actually want to diaper me, Yuzu?" she asked then, softly and genuinely curious.

"Remember what I said last night," she then reminded her sister. "Don't try to overdo it as my big sister and caregiver. If you expect me to drool, and babble in a lisp, and crawl around on the floor like an actual baby... then I'm afraid you'll be very disappointed. But," Mei went on, not wanted to upset her sister, "Yuzu, I would love if you would hold me at times, and rub my hair and my back like I'm a little girl.

"And," Mei added with a small smile, "surprisingly, I do want to try wearing diapers. I can't explain why, but I do want to know what it feels like."

Yuzu nodded, hoping Mei wouldn't be too upset, then listened to Mei very closely. She nodded "Of course, I'm not going to ask any of that, I promise... you are my girlfriend, and my sister, I wouldn't ever do anything to hurt you ever. If that's what you want, I will gladly oblige in any way I can. Now, I will admit I wasn't brave enough to buy diapers yesterday, so that ones gonna take a bit, we'll probably need to do some shopping online. So we'll ease more into that kind of play for a bit." she cooed.

"I know you wouldn't, Yuzu," Mei said. "You're the kindest, sweetest, most loving girl in the whole world. Getting to have you as both my sister and my lover, makes me the luckiest girl in the world. How about... we clear the table and get our teddy bear and cuddle a while, sissy? Then we can do a little online shopping this evening," she added with a twinkle in her eye.

Yuzu nodded with a smile. She thought that was a small tear so she immediately started to wipe Mei's eyes for her and kissed her gently. She scraped the crumbs into the trash, then, with an odd level of ease, picked Mei up and carried her to their room, grabbed the teddy, then laid down on the couch with her girlfriend

Mei was quite surprised that Yuzu could carry her so easily, even though Mei was rather slender. She nestled deep into her sister's arms, cuddling their teddy bear with the heart between them rather adorably. "I love you so much, Yuzu," Mei whispered. And then absent-mindedly, she actually placed her thumb in her mouth and sucked it, falling into a blissful afternoon nap in Yuzu's arms... sucking her thumb and holding her teddy like a little girl indeed.

Yuzu, noticing this, had to hold back a small squeal and took a quick picture of the two of them with her phone, and kissed Mei's cheek gently. Then she closed her own eyes and let herself go to sleep for a bit as well.

After napping blissfully for a couple of hours, Mei awakened to what felt like Yuzu gently stroking her hair. She felt better than she had in, well, since she could remember, actually. Smiling at her sister, she said, "That was really wonderful, sissy. Should we get dinner started, like a couple of helpful big girls? Mom's going to be home soon."

Yuzu nodded with a small smile "Yes of course, little sis, I'd love to help get dinner started for Mom..." she cooed as she went over to the kitchen and started to get some dishes washed that still needed it

Mei got up as well, and helped Yuzu get everything they'd need to make dinner. Mei of course had long been self-reliant and knew her way around the kitchen, but Yuzu was no slouch either... so once they decided what to make, Mei let her sister take charge and helped out in any needed, often without even needing to be told.

It felt surprising nice, actually... applying her knowledge and skill, being helpful and needed, but letting her wonderful, beautiful big sissy lead the process while Mei settled comfortably into the role of the little helper, the darling little sister.

When Ume returned home from her long day, Yuzu and Mei had just finished setting the table, with a nice supper all done and ready.

Yuzu enjoyed Mei helping her around the kitchen, finding her to be kinda cute as she did. Even though Mei rarely needed to be told anything, Yuzu did enjoy the moments she had to give Mei a bit more of a verbal direction, cooing at her just like she was the small girl she was acting like.

Once their mother was home, Yuzu hugged her "Hey Okasan... Mei and I went ahead and made everything... just relax and sit at the table..." she smiled at Ume.
