When Mom's Away... (Patreon)

"Bye, Mom!" Jennifer gave her a big hug. "Have fun!"

Ariana stood back, barely containing her smirk, unsurprised to hear the quaver in her step-sister's voice, or the hint of wetness in her eyes when she turned around. If anything, it was a shock that the brunette hadn't called her mother 'Mommy'.

"Bye, pumpkin," Anita smiled, hugging her back. "This was so sweet of all of you, but I'll miss you!"

Ariana rolled her eyes; she wasn't even going to be gone that long! For Mother's Day, they'd gotten her a private, overnight trip to the spa, just some time to herself to relax and not have to think about anyone else. It shouldn't have been that big of a deal... Ariana and Jennifer were both nineteen, more than old enough to take care of themselves, despite how utterly immature Jenny was.

And, of course, Ariana's dad would be there, too, so they wouldn't even really have to. There was no reason for all this drama, but she'd been positive Jennifer was going to bring it anyway, and she had. She was such a co-dependent little baby... It was almost embarrassing simply to be related to her now. 

"Bye, Anita," Ariana nodded, once Jennifer finally extracted herself from her mother's arms. She was never sure what to do with the woman, whether she should hug her, or shake her hand... For all the time that Anita and her dad had been dating, she hadn't gotten to know Anita all that well,, so a hug felt too familiar; a handshake was definitely too weird and sterile, though.

They settled on a hug, but it was predictably awkward. They watched her go, waving from the front porch, Ariana's grin slowly growing as the car grew smaller and smaller in the distance, knowing that Anita was now too far away to defend her precious daughter from her plan.

It had started back when they'd first made the plans to get Anita this getaway for Mother's Day... Or, really, it had started back when Ariana and Jennifer had first met. "Your dad is so cool," Jenny had told Ariana. "What is he like?"

"I don't know," Ariana had shrugged, already taking a dislike to the girl. "Like a dad, I guess? He's fine..."

But that was all Jennifer wanted to talk about... It was pretty obvious that she had a crush on him, one that she, of course couldn't do anything about, since her precious Mommy was dating him. Or, perhaps, she thought so highly of him only because her mother had already deemed him special by going out with him... It was hard to tell.

Either way, something about that was disgusting to Ariana. Was it jealousy? She was pretty close with her father - though not nearly as close as Anita and Jenny - and it was bad enough having Anita swoop in to steal him... Maybe she didn't want yet another woman to take his attention away from her.  

Whatever it was, she had been wanting to find some way to ensure that Jennifer knew she had no chance with her dad, that she was nothing except a pathetic little girl in his eyes... And, when she realized they were going to have a whole night away from Anita, with all of them resolving not to call or text her unless it was a true emergency, so she could just relax and not worry about anything, Ariana knew this was her shot.

"Hey, Dad?" Ariana knocked at his door, staring down at her shuffling feet, feeling almost as nervous as she was pretending to be, although a lot of it was from excitement, having finally gotten to this point after letting her plan percolate for so long.

"Yeah?" he looked up. "What is it?"

"Well..." Ariana looked around, then stepped into his office, shutting the door behind her. "I need to talk to you about something kind of private..."

"Of course," he shut his laptop, turning around. "Anytime, sweetie, you know that."

Ariana couldn't help smiling; perhaps she should be understanding... It was no wonder Jennifer had a crush on her father! He was a great guy... However, he had been Ariana's father before he was Jennifer's, and she was certain Jenny thought she would have had a real shot at him being something more, if not for her mom marrying him first.

"Well... It's kind of embarrassing," Ariana thought of herself in the position she was trying to put Jennifer in, to make herself blush.

"Don't worry," he nodded supportively. "I won't tell anyone."

Ariana looked back at the floor. "The thing is... I-It's not really about me," she told him. "So, I feel bad telling anyone, but... I don't know what to do!" She crossed her arms, trying to sound upset, instead of excited.

"Just tell me," he said soothingly. "It's all right, Ariana." 

"Well..." Ariana gave herself a squeeze, heart fluttering as she prepared to put the final nail into Jennifer's coffin. "Anita talked to me before she left, and she wanted my help with something... A-And I felt bad saying no, because I didn't want her to have to worry about anything while she was gone, or have any reason not to go, but... I-I'm not sure I can do it, Dad."

"What can't you do?" he asked. 

"A-Anita wanted me to help Jennifer out," Ariana lied. "Apparently, Jenny has kind of a problem, especially when she's away from her mom..."

"A problem?" her father tilted his head. "She didn't mention this to me. What kind of problem?"

"Well, I think she didn't tell you because she didn't want to embarrass Jenny, and it wouldn't be so bad coming from me, but... I-I was never a babysitter, Dad, you know that! I really don't know what to do!"

Her dad sighed, and Ariana worried she might have taken it a bit too far. "I don't understand, sweetie. You're not making sense."

Ariana exhaled a long breath, pretending to gather her thoughts. "Jennifer... wets the bed. Not all the time, but when her mom's not there, it is almost every time. She's really embarrassed about it, and she doesn't like to admit it, but Anita said it happened, and she wanted me to..." She squirmed, her earlier fantasizing about being in her step-sister's position coming back to haunt her, painting her cheeks bright red. "I-I'm supposed to put her in a diaper. I-I don't want to make her feel bad, b-but I have to do something, right? A-And I don't know what to do!"

"I see," her father nodded. Ariana gulped, his words impenetrable; did he see through her? Did he know she was lying?! She was caught between continuing to talk, to try to explain things more, and shutting up to stop herself from digging a deeper hole.

Finally, after a long stretch of silence, he spoke again. "Did she tell you where the diapers are?"

"Uh-huh," Ariana told him. She'd snuck to a drug store, cut open a bag, stolen a single, plain, white diaper. She'd done a little shoplifting in her younger days, but this had been the biggest item... And the one she would have been most mortified to be caught with. Thankfully, none of the workers seemed to have noticed. "W-Well, she gave it to me, since it's the last one she had, I think."

"All right," he replied. "Give it to me, and I'll take care of it."

"Okay!" Ariana was glad to leave, to escape the tension she could feel filling the room. She turned to go and retrieve it, only to be stopped by her father speaking again, the girl freezing mid-step, worried at first about what he was going to say, thinking again that he may have figured out she was lying.

"Thank you for telling me," he said.

"Of course, Dad," she smiled in relief. "I knew you'd know how to handle it."

She had hoped she'd get a chance to see Jennifer in her humiliating, babyish underwear, if just to spot a bit of extra bulk under her PJs, and know it was her who had caused it, and that her father had done it to the girl... But things didn't quite turn out the way she'd planned.

"Hey!" Jennifer poked her head into Ariana's room. "I was thinking, since Mom isn't here... Maybe we should have a sleepover!"

Spending more time with the brat would have been the last thing Ariana wanted to do, except that, this time, it only amplified the chance that she'd be around when the inevitable occurred. "That sounds fun," she said. "Do you just want to hang out in the living room and watch chick flicks?"

"Sure!" Jenny nodded. "We could even wear those PJs we got for Christmas!"

Ariana wrinkled her nose; she hadn't worn hers since she'd tried them on Christmas day, at Anita's insistence. They were one piece, with drop-seats, Ariana's a bright, cheery yellow, Jenny's white, both patterned with flowers. The only way they would have been worse was if they had attached feet, but at least she'd been spared that.

"Yeah, if you want," she agreed reluctantly. If it made Jennifer happy, why not? She was about to be very, very unhappy, after all... Might as well give her one little victory beforehand.

It wasn't too bad a time, sitting there on the sofa, giggling with Jenny, though much of Ariana's enjoyment came from knowing what was coming for her step-sister, what she'd manufactured for her. And, sure enough, as they finished up one movie and were scrolling through Netflix to find another, her father walked in.

"Girls," he announced, "I think it's time for bed."

"Aww," Jenny pouted. "But we don't have classes tomorrow... Why can't...?"

"Jennifer," he said sternly, shutting her up instantly, "don't argue with me, young lady. I'd like to get some sleep, and, in order to do that, I need the two of you to be ready for bed. And, to do that... I need to take care of something first."

Ariana grinned, seeing the puffy, white garment in his hand, knowing what was coming next. It looked even bigger and thicker than she remembered... Would Jenny's stupid drop-seat even close over it?! She could hardly wait to find out...

But, then, he set it down, and Ariana discovered why it looked so bulky. It wasn't just the one she'd brought... There was a second one behind it, one that looked even more babyish, with blue and pink stripes, and little cartoon drawings on the white plastic in the center. Was he going to double diaper her?!

"Come on, girls," he ordered, setting the diapers down, apart from one another. "I've survived enough sleepovers to know that, whether it's from staying up so late, or all the sugar you have, or whatever, someone always has an accident. So I have a rule, don't I, Ariana?"

He gave her a pointed look, and she nodded, though she wasn't sure she liked where this was going. "I know you two are older now, but it still stands. So, come on, you two. PJs off, and onto your diapers."

"B-But..." Jenny blushed, looking frantically over at Ariana, who gave her a shrug. 

"Ariana, you can go first," he said after a moment. "Let's go!"

Ariana gulped, not wanting to argue, to make this seem unusual... But not really wanting to spend the night in a diaper, either. She trudged over, fumbling nervously with her pajamas. "Dad, why me, too?" she whispered when she was over there.

"You said you didn't want to embarrass Jenny, didn't you?" he replied. "This was the best way I could think of to do that."

Ariana squeaked as she felt her father take over, easily whisking her silly pajamas off of her. She covered her chest self-consciously, watching in horror as he took off her panties, too, and made her sit on the soft, crinkly diaper. This would be worth it to see Jennifer go through it, too, she told herself... But, as he taped the diaper into place, she wasn't so certain.

"I can't believe he made us do this!" Jenny whined, fidgeting in her seat, her diaper crackling loudly beneath her PJs. 

At least she'd gotten the plain white diaper, Ariana thought sulkily. She'd been stuck with the more patterned, infantile one, which she hadn't realized until he'd pulled it up between her legs, when she was already feeling so tiny and childish, the padding pushing her thighs apart. She'd almost told him everything, explained that Jenny didn't need a diaper after all... But she'd been afraid of what might happen then.

It had really taken a lot of the joy out of seeing Jennifer get diapered, having to pull on her pajamas over her own diaper at the same time. She could see Jenny's face practically glowing with shame, though she knew her own likely hadn't looked much different a few minutes earlier... And still, to be honest, as she listened to the bulky garment's incessant noise that followed her every move, its warm, sweaty embrace impossible to escape from.

"You two can sleep out here if you want," he told them, once he had the diapers in place, "but I don't want to hear another peep out of you! Understood?"

Ariana had planned on going back to her own bed, but that was when she'd thought she could go change into some normal pajamas, and dream about Jenny in the next room, tossing and turning in her Pampers. Now, that wasn't enough... Now, her plan was evolving, trying to find a way to humiliate her step-sister even more, since she'd had to endure some embarrassment of her own.

"Rules are rules," Ariana shrugged. "I had a lot of friends who were bedwetters."

"But I'm not!" Jenny grumbled. "And you aren't either, are you?"

"No way!" Ariana wrinkled her nose. "You know how he gets when he makes up his mind..."

She didn't think she'd have any problem outlasting Jennifer, but the diaper seemed to have really struck a nerve with her - that, or, like Ariana, she was having trouble getting comfortable in it - and Ariana nearly nodded off a couple times before, finally her step-sister did. Ariana gave her a few minutes, then crept into the kitchen, getting a glass of lukewarm water, not wanting it to be too cold or hot, since that might be enough of a shock to wake her, and pouring it into Jenny's diaper.

Unfortunately, Jennifer was awake before her, so she didn't get to see her reaction, though the girl was still looking pretty disgusted by the time Ariana's eyes opened. And she didn't miss the main attraction, when her father came in, and snapped, "Diaper check time, young ladies! Drop-seats open, diapers out!"

"Wh-What?!" Ariana could see Jenny, almost about to cry. "B-But why do...?"

"Now!" her dad ordered, the two girls quickly scrambling to obey, undoing their dropseats to expose their padding, bending forward to allow an inspection.

"It's okay," Ariana told her step-sister, trying to hide the fact that she knew the answer to the question she was about to ask already. "Nothing happened, right?"

"Umm..." Jenny looked over at her nervously, at a loss for words until her step-father's hand touched her soggy diaper. She still didn't have anything to say then, but she hid her face, while Ariana turned away, doing the same, not wanting either to see how happy she was at her sister's humiliation.

But it wasn't over yet. There was nothing for him to find in Ariana's diaper, and yet, to her surprise, he ordered her to stay bent over, too, returning to the room a moment later with something that made Ariana even happier... Until he approached her with it.

"I asked the two of you to stay quiet," he reminded them, "but I heard you in here talking for hours... So, both of you are getting punished for that, not if you happened to use your diapers."

"D-Daddy?" Ariana squirmed, hoping this was a joke, that he was only going to be spanking Jenny for being a baby and wetting her diaper overnight - even if it had been her doing - but, as she turned to look at him, she felt him drawing a line across her diaper with his finger, giving himself a target...

It had been a long time since her father had spanked her, and, even through the diaper's padding, it was far worse than she remembered. So bad, in fact, that, to her horror, she felt the padding grow warm, and wet, as she had an accident partway through. Now, both of them had wet diapers, which made them equals... Except, Ariana knew that Jenny hadn't really done anything, while she had, in fact, peed her pants like a little girl.

She was too busy blubbering to take any satisfaction from Jennifer's spanking. Afterwards, the two of them were sent to the corner, drop-seats still down, diapers still wet, to, "Wait for your mother to get home, while I work on getting her lunch ready."

After a while, once Jenny's own tears had abated, she whispered to Ariana, "I'm really in trouble now..."

Ariana was a little scared to speak, but she managed a quiet, "Why?"

Jennifer squirmed, blushed. "M-Mommy used to diaper discipline me," she confessed. "A-And when she sees me like this, in a wet diaper, at my age... I-I have a feeling she'll keep me like this for a long time..."

"O-Oh," Ariana gulped, feeling her own soggy diaper between her legs, and realizing what a huge mess she'd gotten herself into, all for the sake of trying to embarrass her step-sister. At best, she'd be getting just as humiliated as Jenny... At worst, if her dad told Anita the whole story... She just had to hope that Jennifer 'wetting the bed' would be enough to earn her some punishment, too, that she wouldn't be the only one who was kept in diapers afterwards, even if she knew she was the one who deserved it.
