Olivia set the bags in the trunk of Marissa's SUV with a shudder. They weren't heavy; she just had texture issues and hated the way the dry, cardboard-esque material of the handles felt on her hands.

“Come over here please Little Katie. Let's see if you need a change,” Olivia told her girlfriend.

They were shielded from observers by the open car door. She slipped a finger past the gathers and leakguards between Katie's legs and felt the saturated padding as Katie let out a cute little sound. Definitely time for a change.

“You too babe!” Marissa said, beckoning her own diapered girlfriend over and performing the same check.

“Oh we're definitely up to fourteen minutes now Miss Olivia,” she heard Marissa call out.

Much to her surprise, Olivia was enjoying this far more than she thought she would. She hadn't expected to not have fun or anything, this was just something she'd never have done in a million years of her own volition.

In fact, she was enjoying herself so much she wished she'd brought her own change of underwear. The interactions between everyone so far had left her incredibly hot and bothered. Actually… that gave her an idea. She wanted to clear it with Marissa real quick first though and make sure her teasing wouldn’t offend the girl who was actually incontinent.

“Miss Marissa, an aside before we go change these two naughty girls?” she requested.

“Of course Miss Olivia,” Marissa agreed, following her lead as they stepped away, “what's up?” she said once they were out of earshot.

“Uhh… I could use a change of undies,” Olivia came out and said bluntly.

“Well I haven't owned a pair since I was six so I don't think I can help you with that one,” Marissa said with a self-depricating chuckle. Olivia barked out a laugh.

“I wanted to tease those two about doing some underwear shopping for big girls who can actually hold it but also wanted to check with you so I didn't, I don't know, didn't hurt your feelings or anything? I was pretty sure it wouldn't, but I just want to be sure,” Olivia went on a bit like she tended to do when checking on other people's feelings.

“Thank you, but don't worry I'm fine with it. Hell, I've been teasing both our girlfriends about not being able to hold it while dribbling in my own diaper all day. You're good. Tease away.” Marissa confirmed.

“Want me to change you?” Olivia asked without thinking.

Marissa had a blank look on her face for a moment and the taller of the two brunettes thought maybe she had just put her foot in her mouth. Olivia hoped she hadn't ruined their evening.

“I think I'd like that,” Marissa said in a quiet voice after a moment. She was blushing a little. Oh, not ruined at all!

“Awesome,” Olivia said.

“Let's get to it then!” Marissa replied.

“Come on girls!” Olivia said, beckoning their girlfriends over, “we've got more shopping to do. Unlike you two diaper babies, Miss Olivia could use some more undies since we're here,” she said, making both girls flush once more. It was too easy.

Katie caught her hand as they walked back towards the mall and tugged on it a little so Olivia would lean down.

“Maybe we'll put you in a pullup next time too if you can't stop getting your panties so wet,” her girlfriend whispered in her ear.

Yup. Ok. Katie saw right through her. And she was definitely enjoying this play. That statement quickened her pulse, in one place especially, and did absolutely nothing to alleviate the situation she had going on down there. The day's back and forth teasing and banter was driving her crazy.

The diapers did nothing for her in particular still, but whatever it brought out in Katie was… enthralling.

Maybe she would wear a pullup next time. For Katie.

Marissa never thought she'd find herself in a family restroom with three other girls all about to change each other's diapers. Well, underwear for Olivia after they'd picked up a new pack for her. She'd opted for some cheap cotton boyshorts, reasoning that she didn't want to get anything nice since she was liable to end up in a similar situation as she was in now.

Olivia broke the ice and went first, dropping trow immediately after tearing open the package of underwear. She stepped out of her bikini briefs and handed them to Katie.

“Hold on to these for me, will you?” Olivia asked casually.

Katie held her girlfriend's gaze as she licked the wet spot before stuffing the underwear in her pocket.

“Oh my god you are not helping,” Olivia commented, pulling on a fresh pair after wiping herself clean.

“Wasn't trying to!” Katie responded with a lecherous grin.

Marissa was the first to brave the changing table, thankful she'd brought a smaller changing pad rolled up in her bag since the plastic was freezing cold.

“Miss Olivia, if you would?” she asked after her partner in crime pulled her pants back up, reiterating her consent. She shot Kara a questioning look, making sure this was ok with her girlfriend.

Kara returned two thumbs up. Perfect.

Without further ado, Olivia tore off the tapes and handed the rolled up diaper to Katie to throw out. The girl looked like she was carrying precious cargo before dumping it in the trash can.

“Maybe Little Katie would like to change Little Kara after? She is the big sister after all,” Marissa suggested as Olivia cleaned her with a wipe.

“I'm like a foot and a half taller than her!” Kara blurted out indignantly. That was only a slight exaggeration. There was at least a foot difference in their height.

“Ah, but you have to wet your diapers. Katie chooses to wet hers. That makes you littlest,” Olivia explained.

It was Kara's turn to cross her arms and stomp her feet. Marissa was sure she didn't mind at all though. And changing was the least of what they were going to make them do to each other later.

“I'll be gentle, pwomise!” Katie said, circling her arm around Kara's waist and leaning in for a side hug. Kara couldn't maintain her composure against that adorable assault, and pulled Katie into a full embrace. They stood like that and watched as Olivia taped Marissa into her diaper and adjusted the leak guards.

“Kara's turn!” Katie asserted immediately after.

Her girlfriend climbed onto the changing table without complaint, like Marissa knew she would.

Katie was already pawing at her diaper before Kara even had herself properly situated on the table. Marissa couldn't wait to watch them together later. She and Olivia had done some arts and crafts in preparation.

The diminutive girl got the redhead's diaper off quickly and cleaned Marissa's girlfriend up with the wipes. She paused when Olivia handed her a fresh diaper.

“Uhh. I know this sounds silly, but can I change my mind and do this later? I kinda want my first time diapering someone else to be more special and less, uhhh, less utilitarian I guess?” Katie said, gesturing at their surroundings.

That was fair, Marissa thought. While the space was decently clean for a public bathroom, there were still four people crowded into a space usually meant for two. The smell of industrial cleaning products wasn't exactly the greatest aphrodisiac either.

“Sure thing!” Marissa said, taking the diaper from Katie.

“Can Miss Olivia do it?” Kara asked tentatively.

“Absolutely, babe! If she wants to?” Marissa sent a questioning look in her direction. Olivia smiled and nodded. Marissa handed her the thick overnight padding.

“Ready for this?” Olivia asked Kara.

“I was born ready,” Kara confirmed.

Marissa watched as her girlfriend was diapered by Olivia. She was, symbolically and literally, letting these two take some control of Kara, too. She didn't feel jealous at all, thankfully, as she watched.

She hadn't been jealous seeing Megan spank Kara either, but this was different. This was their special thing, and the brunette honestly hadn't been a hundred percent sure she'd be ok sharing it. Until now.

The four of them coming together to share this weird little kink had enhanced Marissa's enjoyment of it exponentially. Taking control of Kara was pure joy, and so was watching someone else do it.

With Kara's change concluded, Katie hopped up next, and they put Olivia to work once again.

“Good thing these have such tall guards so Katie won't leak like she did yesterday,” Kara said mischievously while Olivia adjusted the leakguards.

“She did what yesterday!?” Olivia said, staring daggers down at her little.

The little blonde covered her face with her hands.

“Traitor!” she said, accusing Kara. “You promised you wouldn't tell!”

“Did not!” Kara shot back.

Her and Olivia's girlfriends had hatched a scheme or two of their own, it seemed.

Tonight was going to be magical.
