"Yes, I'm still making lots of friends," Mara lied as she stood there in the foyer, letting her aunt check her training pants. It was getting worryingly familiar, coming home and having her pants pulled down, the older woman poking and prodding at the padding around her waist, as if she had just been at preschool, not college. 

"I knew you would!" her aunt gushed. "You just had to stop being so shy and nervous, and thinking everyone cares about what you wear. All you had to do was tell them the truth!"

Of course, most of the reason Mara was being bashful was because her aunt insisted she wear those silly Pull-Ups. She was certain everyone knew she had them on, so she couldn't bear the thought of actually striking up a conversation with them, sure they'd just make fun of her. Besides, she'd moved here to learn, not make friends... 

The university was very good - it had been quite the shock when she'd been accepted - and very expensive, and part of the way she was affording it was staying with her aunt, who luckily lived nearby, instead of on campus. At first, it had seemed like the perfect arrangement... She didn't know her aunt that well, though she did know the woman was quite well off, and had plenty of room for her to stay. If they got really close, perhaps the woman would even offer to pay her tuition for her! It was a long shot, but stranger things had happened.

Unfortunately, things quickly soured once Mara had actually arrived, and returned to her room from taking a shower to find her aunt sitting on her bed, Mara's underwear spread out around her. "What is this?!" she demanded, gesturing towards a pair of underwear with a slight stain on them. "And this?!" she pointed at another. "Do you have something you need to tell me, young lady?"

Mara had, of course, told her it was no big deal, that they were simply old, but her aunt refused to listen, saying that she hadn't put together such a nice house just to have some little girl ruin it with her faulty potty training. Mara's insistence that her potty training was perfectly fine had earned her a spanking, an hour in the corner, and had done nothing to stop her aunt from continuing with her plan to see just how well trained she really was.

Mara really had been potty trained for many years; her aunt, however, had some very strict tests, and clearly a far bigger bladder than her niece, not to mention a much earlier bedtime. Mara had a daytime accident or two, though most of the trouble came because her aunt diapered her for bed before she went to sleep, so the girl had to make it through the entire night, which, no matter how little she drank during the day, seemed all but impossible. When she'd caught Mara sneaking to the bathroom after bedtime, she'd actually bought her an oversized crib to sleep in, to ensure she stayed in bed!

She did allow Mara to go with just training panties during the day, which the girl supposed she was grateful for, given the alternative... Even those were much thicker than her usual underwear, enough that she was positive everyone knew about them. She'd complained to her parents, without getting into the humiliating specifics, but all they said was she needed to follow her aunt's rules, now that she was living under her roof rent-free.

"Good girl," her aunt complimented her. "Dry again!"

"Uh-huh," Mara nodded. It was much easier at school, out from under her aunt's constant supervision, although the first few days she'd been so scared someone would hear her pulling the trainers down in the bathroom that she refused to even try it when there was anyone else in the room with her, even several stalls away, which had led to a couple accidents. "It's been almost a week now, can we...?"

"We've talked about this," her aunt sighed. "You have to stay completely dry a week, and you're still having trouble at night, aren't you? And, speaking of that, we'd better get you ready for bed."

"What?!" Mara whined. "But I just got home..."

"And you didn't do your chores again yesterday, did you?" 

"I-I think I did..." Mara thought back, chewing on her bottom lip as she ran through the list of chores she was supposed to do. She knew she'd done the dishes, and did some dusting, but had she finished all of them? She honestly couldn't say... "I-I might have missed one..."

That was all it took. "You know what that means, young lady... Off to bed without supper!"

"B-But..." Mara protested. Bed this early meant a definite wet diaper the next morning, and likely something worse. "Can't I just..?" She groaned, suddenly wishing she'd gotten up the courage to go to the bathroom one more time before heading home for the day. She hated pooping in public restrooms, though, so she'd decided to hold off... Clearly, not a great plan for today.

"Rules are rules," her aunt shook her head, grabbing Mara's arm. They had agreed to that, it was true, and Mara had told her aunt she'd help out more around the house, to prove she was a mature young adult.... Surely she wouldn't punish her today, though... 

She had to know it was Mara's birthday, didn't she? Mara had been getting birthday cards in the mail for the past week, although, come to think of it, she had opened them in private, without showing them to her aunt. The woman hadn't mentioned it to her that morning, or asked her if she wanted a cake or anything... And, while she had gotten birthday cards from her in the past, usually with a large check, they were almost always at least a couple weeks late. Maybe she really didn't know what to day was.

As if to prove that, she led Mara back to her bedroom, laid her out on the crib mattress, and taped her into a thick, nighttime diaper before helping her into her pajamas. All the while, Mara debated telling her, not knowing if that would get her some leniency, or just embarrass the woman. Before she could decide, her pacifier - bought, along with these pajamas with the mittens over her fingers, because her aunt had caught her sucking her thumb in her sleep one morning - was popped into her mouth, the side of the crib locked in place, and the lights turned off.

Mara sighed, looking around her room, still lit quite well from the sunlight streaming in under her curtains. Was this really how she was going to spend her birthday? Stuck in here, no cake - or any supper at all - staring at the walls of what might as well have been a nursery, sucking on a pacifier, wrapped snugly in a diaper, for all intents and purposes having just turned nineteen months old rather than nineteen years.

Mara groaned as another cramp hit her tummy, wrapping her arms around herself. It just wasn't fair... This shouldn't be happening to her... She had no doubt her aunt would have plenty to say if she found Mara in a messy diaper the next morning, but what choice did she have? It was going to happen sooner or later, and her stomach had been feeling very full for quite a while. There was no way she could make it... Maybe, if she just went, she'd feel better.

She squatted down, trying to pretend she was using a toilet, to forget about what was really happening. She closed her eyes, biting into her pacifier, and began to push. Instantly, as she felt the mass squeeze its way into her diaper, she knew she'd made a mistake, but it was too late... She gasped, fighting to stop the warm mush as it oozed its way out, more and more, creeping through every inch of her bulky padding, yet, now that it had begun, it just kept coming...

"Surprise!" Mara gasped as the bedroom door was thrown open, the lights turned back on, her aunt marching in, followed by more and more other students, each one making Mara shrink down a little more, wishing she could vanish completely. Quickly, she lowered herself, not wanting anyone to see what was happening, certain the bulge had to be obvious through her PJs. "You didn't think I'd forgot, did you? Happy Birthday, sweetie! I'm friends with one of your teachers, so I had her invite your classmates, since you're doing so good at making friends.... I have a lovely party set up in the living room, which is why I had to put you to bed, so you wouldn't see it before they arrived. Now, what do you have to say?"

Mara stared around at them, seeing them quietly snickering to one another as they saw her there in her crib, wondering if they could smell what she'd done yet. Anxiously, she reached up, clumsily grabbing at her pacifier with both hands, eyeing her aunt, wondering what she was going to do when she found Mara had filled her diaper, just minutes after being put into it... And whether she would do it here, in front of her classmates. "Th-Thanks for coming," she stammered, watching her aunt's nose wrinkle, her expression change, and realizing she was about to become not just the guest of honor at this party, but also the entertainment.
