Mei slipped the diaper beneath Yuzu's adorably cute bottom, pulled up the front, and taped it snugly in place. She grinned at her sister and gently patted the diaper in the thick, bulky crotch. "I like you like this, Yuzu," Mei said. "Big sissy or not, these cute diapers really suit you."

Once both girls were happily and snugly diapered, Mei leaned over Yuzu and gave her a long, soft, passionate kiss... not unlike the very first time they'd kissed so many months ago, but a bit more gently and full of love this time.

Yuzu giggled and kissed back, she seemed happy to be in a diaper. She shifted around a bit then sat up and kissed Mei's cheek "Ah thats nice." she grabbed her phone and, after cropping out the kiss, sent the full change video to Harumi, figuring the girl would appreciate it.

Harumi smiled when she got the video message. It was nice to see Yuzu enjoying herself, and truly precious to see just how connected the step sisters so clearly were... even without seeing the kiss.

Mei, meanwhile, smiled contentedly and held her sister and lover close for a long moment. "So," she said eventually, "what now, Yuzu?" It was still early in the evening after all.

Yuzu chuckled "A fair question sister, I don't really have anything special planned. I honestly wasn't even expecting you to go along with this as easily as you did..." she smiled at Mei gently.

"Well," Mei reminded Yuzu gently, "I did say I wanted to try wearing diapers from the first time you brought it up. After all, we went shopping online last night and everything. And," she added with a playful little smile, "I really can't wait to wear my pink princess diapers."

Mei kissed Yuzu, softly and passionately, once again and nestled even closer, so that their bodies gently and warmly pressed up against each other.

Yuzu smiled "Yes, you did, I just wasn't totally sure how much your heart was in it dear sister..." she cooed, and kissed Mei gently now that she was much more sure that Mei was completely into it, then she returned Mei's kiss as well. "Hm... do we just wanna rest here? Or do something for now?"

"Actually," Mei said, "it might be nice to just rest and relax together. As you know I've been so busy with student council lately, so I've been more tired than usual. But, we should have everything finished tomorrow, so then it's back to just our usual after school tasks, which will be much easier.

"I promised Himeko I'd take her out to celebrate on Saturday," Mei added. "The poor thing has been trying so hard to be OK with you and me, Yuzu. So it'll be nice to spend a little time with her. But after that..."

Mei kissed Yuzu one more time, then lay down on her side of the bed and took hold of their special teddy bear with the heart. And she patted the bed next to her, motioned for Yuzu to lie down with her... to rest and relax, and to stay close.

Yuzu nodded "Very well." she smiled as she rubbed Mei's back and laid down on their bed with her, deciding to remove her skirt completely so she could just look at her padding as they did. She was happy to hear that things would calm down soon for her sister though.

She then nodded "Yes that's perfectly fine Mei. Perhaps I'll go out and do some more stuff with Harumi, learn a bit more about this whole thing and how to care about my cute baby sister." she teased a little as she poked Mei's nose.

"Alright," Mei said, laughing softly. She removed her skirt as well, so that both sisters now had their cute, somewhat bulky diapers on full display. "You know," she went on, "I'm happy to learn more about this together, Yuzu. If you want to have Harumi over sometime, so we can both talk to her, I'm happy to get to know her better. She's been a really good friend to you ever since you came to the Academy, even before all this, hasn't she?"

Mei then reached over and gently, playfully patted and rubbed Yuzu's diapered bottom a bit. "I really like how these look on you, Yuzu," she said, a bit of a glint in her eye. "And how they look and feel on me too," she added.

Yuzu nodded "I'll talk to her about it, I'm sure she'll be happy to come over, especially when she's 100% certain that I am in no way making you do anything. She seemed to be oddly worried about that... but yes, she was my first friend here at the academy, I care about her almost as much as I do you and Mom."

Then she chuckled "Yeah, I do enjoy the feeling as well. Besides, diapers are good for making your butt look bigger and sexier than it already is." she joked crudely
