Chelise had fallen asleep in the back of Selene’s car. Selene thought that the girl looked absolutely adorable while she snoozed away. She was in her booster seat in the back of the car. It was a seat that rested just on top of the car's natural seat and kept Chelise secure with a five-point harness and a locking buckle. The seat was had a white cover decorated with little pink and purple bows. Chelise’s dress, a light purple dress with subtle volume in the skirt was being pinned to the side by the crotch strap offering an unobstructed view at the diaper underneath. It was a white and pink diaper with a unicorn themed print. The magical rainbows had long since faded from the diaper. It had been a lengthy drive and Chelise’s diaper was showing it. A darker red pacifier hung off the dress’ collar with a black clip. It had fallen out of Chelise’s mouth when she fell asleep, but before that she was dutifully suckling away at it. An almost empty adult sized baby bottle rested in one of the cupholders on the side of Chelise’s booster seat, another sign of how well hydrated her mommy kept her.

Selene smiled at the sight of her baby girl in the rear-view mirror. It was a sight she had gotten used to. Chelise being her baby girl had become so normalized lately. It seems the girl’s last bit of resistance had left after she had lost a fateful bet two months ago. Since then, Chelise had been a remarkably compliant baby girl, and she had really shone in her new role. She had gone from: being pouty about being put in pull-ups, to requesting the extra thick diapers with the cute prints, from being mad at wearing diapers in public, to picking out outfits that deliberately showed them off, and, most relevant to Selene’s current view, Chelise had actually requested the new booster seat she was currently snoozing in. She would deny that she picked it because of its locking buckle and optional wrist and ankle restraints, but Selene knew her better. She also knew better than to press when she had a good thing so she gladly let her baby girl sit in the booster seat with “more cushion on the back.”

Despite how well Chelise had been behaving lately, Selene was worried about today. They were heading to a small amusement park, and one of Chelise’s old friends was supposed to be joining them since she lived nearby. Selene was worried seeing an old friend might bring up some old behaviors since this friend hadn’t yet seen Chelise in her new adult baby state. Regardless, Chelise would be playing the part of adult baby today. She made a commitment to live that way after losing that bet, and Selene wasn’t about to let her get away with shirking it, no matter what her friend thinks. For now, Selene was enjoying the sight of her compliant baby girl before the brattiness got to her.

Sadly, all good things had to come to an end. Selene stopped in front of a modest town home. Her GPS silently notifying her that they had arrived at the friend’s house. The plan was to pick them up and then head to the park.

“Wakey wakey baby girl,” Selene sang. Chelise woke with a slow start.

“Are we there?” Chelise asked slowly waking up.

“We are. Did you get a good nap in your new car seat? Got enough back support?”

“Yeah,” Chelise said with a bit of a blush.

“Good. Let’s get you out and check that diaper. I can tell you probably need a change from up here,” Selene said as she got out of the car. In the brief moment between her mommy getting out of the car and letting her out of her car seat, the weight of what was about to happen hit her. She hadn’t seen Lyra in person in a while, not since she got wrapped up as Selene’s baby, and now she was about to meet her in a full diaper. It was one way to deliver the news.

Selene opened the back door and pressed her special key into the buckle of Chelise’s booster seat to unlock the buckle.

“Are you gonna change me out here?” Chelise asked hopefully.

“Now why would we do that?” Selene responded. “I’m sure your friend has a comfier place to get you changed than in the back of the car.” Chelise looked to Selene with worry as her mommy helped her out of the car. “It’s not like you can hide it from her baby girl.” Chelise looked down as Selene gently grabbed her hand and made her way to the door, gently knocking on it three times. Chelise tried her best to flatten out the dress to hide her diaper, but it was one of the ones she picked out because it offered diaper peeks so the effort was mostly pointless.

After a moment, and some shuffling behind the door, it finally opened. On the other side was Lyra. A girl that was closer to Chelise’s height than Selen’s but still taller that Chelise. She sported a light blue t-shirt and a rainbow skirt.

“Chels! It’s been too long,” she said happily hugging her friend, freeing her hand from her mommy’s grasp.

“Yeah, it really has,” Chelise said nervously as the hug ended. “I’m sorry about that. Things have been … busy.”

“Oh, you’re fine, it doesn’t help that I live so far away …” There was a pause as Lyra studied her friend’s face and the nervous expression plastered on it. “Everything all right?”

“Well, uh … I mean I uh … We uh …” Chelise stammered trying to find the right words to say she was living full time as an adult baby now-.

“Do you mind horribly if I change my baby’s diaper inside,” Selene was blunt where Chelise couldn’t find her words.

“Change? Your? Diaper?” Lyra looked to Chelise with shocked confusion. Chelise tried to hide in herself, unintentionally lifting her skirt a little and proving that she was, in fact, wearing a diaper.

“I uh … could use a diaper change,” Chelise said with a deep blush. Selene smiled warmly behind her.

“Well, I uh …” Lyra didn’t quite know how to respond. “Sure,” she stood out of the way as an invitation to her home and Selene entered with a still blushing Chelise.

*****

Lyra couldn’t help but stare as Chelise was buckled into her booster seat by her mommy. Lyra elected to sit in back with her friend, so there was nowhere for Chelise to escape to. Once she was strapped in. Chelise chanced a look to Lyra only to look away with another blush.

“So, diapers huh?” Lyra finally broke the silence.

“Yeah diapers,” Chelise admitted as Selene got in the driver’s seat. “I’m sorry. I should have told you.”

“It would have been nice,” Lyra admitted.

“It just doesn’t really come up in our text conversations,” Chelise gave a cute shrug from her car seat.

“Sorry. I never thought to ask if you need a diaper change while we were talking. Seems like I needed to soggy butt.”

“Soggy butt?!” Chelise exclaimed at the sudden teasing. Selene giggled from the front seat and Chelise fired a look through the rear-view mirror.

“Well, you’re not soggy any more, but your used diaper is in my trash can.”

“I hope you don’t mind dear,” Selene offered an apology.

“Oh no it’s fine,” Lyra said with a smile. “You know I’ve heard a lot about this adult baby stuff and I’ve been a little curious. I never knew I would find one so close to home. Well, metaphorically anyway. I’ll have to ask your girlfriend, I mean mommy, all kinds of questions.”

“I’m happy to answer dear,” Selene said helpfully.

“Don’t embarrass me mommy,” Chelise complained.

“Isn’t being embarrassed part of the point?” Lyra asked thoughtfully.

“She’s clever,” Selene giggled. “I like you friend.” Chelise pouted playfully, but shared a look with her friend. For the first time since this news was rather abruptly revealed, she was able to maintain the look for a time. She found herself feeling happy that the reveal went as well as it did despite how sudden it had to be. It was still weird to think about her friend teasing her for wetting her diapers like her mommy did, but Chelise couldn’t deny that she found it nice as well.

The drive from Lyra’s house to the amusement park was thankfully short. Selene pulled into the only lightly crowded parking lot and Lyra eagerly exited the vehicle. For once, Chelise was annoyed by being locked into her car seat, but her mommy was quick to come around to let her out.

“So how is this gonna work?” Lyra asked as Selene helped Chelise out of the car. “Can you ride all the rides bien a baby an all?” Chelise was about to move away to answer but Selene had a practiced grip on her hand.

“I’ll have to see the ride before I’ll let her on it,” Selene brought Chelise close to her. “But don’t let us stop you. You can ride whatever you want. I’ll make sure baby girl waits for you.” Selene punctuated this by grabbing a harness from the car.

“Mommy!” Chelise complained quietly on seeing the harness.

“Oh, come on now,” Selene said calmingly as she expertly secured Chelise into the harness. The harness was a light brown color and wrapped around her chest. The front had a large panel that was decorated with a whit cartoon horse that matched Chelise’s diaper, which was a fact that Chelise normally loved, but now she was embarrassed by. Once the harness was on Selene attached a chain set of reins to the back of the harness. “It’s a huge park with tons of people. You can get lost in the crowd. This is what baby leashes were made for.”

“But …” Chelsie started but she was cut off by Lyra.

“Do you have a stroller for her?” Lyra asked. “I bet that would be so cute.”

“I’ve been shopping around,” Selene smiled as she got a confident hold on Chelise’s reins. “Check back next year.”

“I bet a stroller here would be great honestly.” The group moved to the park. “After standing around all day my feet are killing me. It’d be nice to just be sitting most of the time. I’d probably sneak a seat while Chelise goes on a ride if you had one.”

“Maybe we’ll get a double stroller,” Chelise said spitefully.

“I wouldn’t wanna take attention away from the baby girl,” Lyra said missing the snideness in Chelise’s response entirely, which made Chelise feel a little bad about it.

“I may not get to chill in a stroller, but at least I don’t have to wait in the potty line,” Chelise smiled as the group walked past a long line for the bathroom.

“You’re not wrong,” Lyra giggled. “I like being a big girl though.”

“Seems overrated,” Chelise said, her usual cheerful nature returning.

“Sure, thing cutie,” Lyra said with a smirk.

The group made their way to a central pavilion in the park, from which they could see most of the rides. Despite how often she had done something like this and how accepted being a little had become, Chelise sometimes found herself feeling a little self-conscious when she went out in public. Selene was quick to pick up on this feeling so she quietly patted Chelise on the head.

“I’d like to ride something together to start,” Lyra was looking at the map of the park and all the rides, totally oblivious to Chelise’s moment of self-consciousness. “What do you think Selene? What can the baby ride?” She turned around and only then noticed the shift in mood. “Everything ok?”

“Yeah,” Chelise shook her head and moved past the moment. “Sorry sometimes I still get a little …” she waved her hands around and giggled.

“Well, I think you are adorable, and I just found out about this baby thing like an hour ago. So don’t even feel all,” Lyra too waved her hands around in a similar way to Chelise. Chelise laughed and grabbed her friend’s hands.

“Thanks for that Lyra,” Chelise said smiling.

“Of course,” Lyra smiled back. “Now are we gonna ride the screaming terror …”

“Mmm mmm,” Selene nodded no.

“Or the tipsy coaster?” Lyra finished.

“She can ride the Tipsy coaster,” Selene said smiling.

“Awesome! Hey Selene do you think I …” Lyra started but then stopped and directed the question to Chelsie. “Chels would you be ok if I held your reins while we walked to the ride?” Chelise immediately grew bright red at the question. She looked to Selene who sent the question right back to Chelise with a look.

“Uh I …” Chelise somehow grew more red. She looked to Lyra who was giving her best puppy dog eyes. “Fine,” Chelise said quietly.

“Yes!” Lyra pumped her fist and eagerly grabbed the reins from Selene.

“Now these are reins not a leash, so you have to make sure the baby takes the lead and walks ahead of you,” Selene offered advice.

“Mommy!” Chelise whined.

“Thanks Selene!” Lyra took the advice with a smile. “Go on cutie, let’s go.”

“You’re pushing it,” Chelise grumbled.

“Don’t you have a paci to put in.” Chelise sighed and did just that, putting the pacifier clipped to her dress in her mouth. “So cute,” Lyra cooed as the group made their way to the ride.
