It was almost a relief, being told over the phone, "Oh, we aren't having a birthday party this year." After all, considering what had happened to Sierra at those the last few times she'd gone, or tried to celebrate Zoe's birthday in general, she knew it probably wouldn't have ended well for her.

Still, she couldn't help but ask, "How come?" It had become such a tradition that it was weird not to have to worry about what to get the girl, or going to see their friends.

"She's off at school," Sierra was told. "I'm afraid she won't be back on holiday for quite a while, but you can always come visit her when she returns."

Sierra nodded, before remembering she was on the phone. "Okay," she said. "Thanks!"

It seemed strange, thinking of Zoe being the one off at school. What kind of place was it, she wondered. They were probably celebrating her birthday. She hoped the girl was having fun!

___________________________________________________________

"And what do you have to say for yourself, young lady?"

Zoe squirmed in the chair, her diaper crinkling beneath her as she tried to put together an acceptable excuse. She'd found herself here, in the headmistress's office, plenty of times since starting school here, and usually she was just given a spanking and sent back on to classes. This time, however, she got the feeling it wouldn't be so simple.

"It's my birthday," Zoe finally replied. "I just wanted some chocolate pudding."

The headmistress sighed. "Didn't you think you'd get some at lunch? You could have waited and at least asked before sneaking into the kitchen and trying to steal it."

"I guess," Zoe shrugged. "But I wanted it now!"

"I'm sure you did," the headmistress shook her head. "Just like you wanted it last week, and the week before. Surely, you must realize by now, it isn't going to work. They know to watch out for you now, and you would be the only one in there in uniform."

'Uniform' was something of a strong word for what Zoe, and the other students at the school, had to wear. It was a ruffly crop top, thigh highs, flat Mary Janes, and a diaper. She didn't mind it, definitely not as much as a lot of the other people there, but she wouldn't have thought to call it a uniform, either.

"I'm sorry," Zoe sighed. She knew that was what the woman wanted to hear, so, even though she couldn't quite make it sound sincere, she went ahead and said it, hoping that would get her out of the office without a paddling.

"I'm afraid that just isn't enough this time," the headmistress shook her head. "We've been over this time and time again, and you just aren't learning!"

Zoe rolled her eyes. "Okay, get it over with," she stood up, leaning over the woman's desk, sticking her padded bottom in the air. "Go on, spank me, even though it's my birthday."

She'd hoped for a little sympathy, and, while she didn't get that, the headmistress also did take her up on the offer. "No, that won't do, either," she said. "We've tried that, and the lesson doesn't seem to be sinking in. We're going to have to try something a little more... extreme."

"Extreme?" Zoe wasn't sure what that meant. What other kind of punishments were there? Time-outs? Line writing? Enemas?

"Yes," the headmistress nodded. "We have to make sure nobody else tries to follow your lead. We're going to make an example out of you."

"But what..?" Zoe began to ask, only to be silenced by a pacifier being pushed into her mouth, a strap wrapped around her head and locked to keep it in place. She glared at the headmistress, pouting.

"I'm sorry, but this is the way it has to be," the woman told her, pulling a pair of padded mittens on over her hands to keep her from being able to use her fingers. She spread a changing pad out on her large, wooden desk and gave it a pat. "Now, up on my desk, we have some work to do."

That work, at first, just seemed like a diaper change, which Zoe didn't mind, since she was pretty wet. The headmistress cleaned her up, sliding her old, wet diaper out from under her and putting a new one in its place. She followed it up, however, with a second, and then a third. Zoe was double diapered at night, but she'd never had to wear three here! That was probably the punishment, she assumed. Everyone would be able to see, from the extra bulk, that she was being punished, especially combined with the mittens and gag.

But the headmistress wasn't finished. She reached into her desk, pulling out a number of decidedly more naughty looking toys than any Zoe had seem at this school since arriving. Students definitely weren't allowed those! "Just relax," the headmistress told her, taking the girl by surprise as they were carefully inserted, then held in place by the trio of snug diapers.

Zoe couldn't help letting out a gasp as she squirmed on the desk, feeling the toys inside of her, almost not even noticing when the headmistress pulled a pair of plastic pants up over the whole thing. She definitely didn't see the lock on the front until it was clicked shut.

She also didn't notice the wires dangling from the things inside her, or the remotes at the ends, until the headmistress helped her to her feet, tucking the remotes into the tops of her thigh highs and leading her out of the office and through the halls. Zoe's face was bright red as she passed other students, and teachers, wondering just how much of what had been done to her they could tell just by looking at her.

They wound up at the cafeteria, where Zoe saw the sign hung on the wall, and the mat laid out on the floor, and knew it was waiting for her. She tried to mumble another apology through the gag, but that didn't stop the headmistress. There were a few other things waiting in her spot, too, including the strange tank that was strapped onto her back, and the ropes hanging from the ceiling, holding her arms wide, make extra sure that she couldn't stop what was going on, or get out of her diaper ahead of time.

The headmistress tied her ankles together, then put a bib saying, "Messy Baby!" around her neck as a finishing touch. "There," she declared, surveying her handiwork. "This ought to make sure nobody tries to follow in your footsteps, or they'll get the same treatment. Now, lunch will be starting in a few minutes. I'll go ahead and let you get a head start."

Zoe glared, struggling in vain against her bonds. "You wanted chocolate pudding," the headmistress said, pulling a tube out of the tank on the girl's back and slipping it into her diaper, "Here you go!" She flipped a switch, and instantly, the tube began pumping cool, squishy pudding into Zoe's pants. "And, to make sure you really 'enjoy' it..." The woman bent down, switching on the remotes tucked into Zoe's stockings.

Zoe's eyes widened as she felt the toys begin to vibrate. It had been a long time since she'd felt anything like that, especially three at once, and, despite her situation, it was hard to resist, hard to keep from moaning into her pacifier gag as she felt the pudding gushing out into her triple diaper, even when the other students began to filter into the room, seeing her standing there, on display, the sign above her letting them know exactly what her crime was, what had landed her here, diaper getting fuller and fuller as the toys continued to buzz away, bringing her to orgasm after orgasm, through all of lunch.

"Oh, what could it hurt?" Sierra shrugged.

She supposed she could have waited until Zoe got back for whatever break was soonest, but it just wouldn't be the same. She'd celebrated so many birthdays with the girl by now, even if they usually went badly for her, that it seemed wrong not to at least see her this year.

It would be quick, she decided. She could just pop in, say happy birthday, and then leave. She didn't want to disrupt things too much, or distract Zoe from her studies. She had no idea what sort of school it was, or what Zoe was studying, but she didn't really have to. Magic was useful that way, and she knew Zoe well enough to be able to hone in on her essence for a location, then she just had to copy whatever most of the people in the area were wearing to get herself a uniform to make sure she blended in.

With a quick zap, she'd done it, although, as the dust settled, she began to regret her decision. Instantly, she knew she was wearing a diaper, able to detect that crinkly bulk right away, even before glancing down to see that she didn't have anything over it. Her shirt didn't even come close to covering it, either, and no amount of stretching would make it long enough, either.

She blushed, feeling incredibly self-conscious, even after looking around the hallway to see that everyone else was dressed the same. She supposed it really wasn't a huge surprise that Zoe would be somewhere like this. She probably should have seen it coming, even, but she hadn't.

There was no way she was going to run around like this, and she especially wasn't going to let Zoe see her this way. She spotted a little alcove and headed for it, wanting a little privacy so she could use another spell to change, instead, into what the teachers were wearing.

Before she even reached it, however, one of those teachers stopped her with a strong hand around her wrist. "What is this?!" she demanded.

"Umm..." Sierra stared up at the woman, unsure what she was talking about at first. Had the woman seen her apparate in? Was there some little detail of the uniform that her spell had gotten wrong?

"We do not bring sticks inside, young lady!" the teacher informed her, snatching the wand away before Sierra could protest. "Honestly, you girls... I'm going to go throw this outside!"

"No!" Sierra protested.

It was the wrong answer. The teacher glared at her, then dragged her into a small classroom. There were four stools, each positioned in one of the corners, and a teacher sitting in the middle. She knew right away why Sierra was there, taking her from the first teacher and pushing her down onto one of the small, hard stools, making sure she stayed there while the first teacher headed off, taking Sierra's wand with her.

Sierra also quickly, after her timeout was over, anyway, found that going outside wasn't an option for her, either, as the doors were being closely watched. Finally, she decided to look for Zoe, sure that the girl would know how to get past them.

When she asked around, hoping some of the other students would know what class she'd be in, most of them just giggling. It took a while before one of them told her where her bedroom was. "Shouldn't she be in class now?" Sierra asked, and even that student began giggling at that.

Even if she wasn't there now, Sierra decided waiting in Zoe's room would be the best course of action. She didn't want to wind up stuck in any of these classes, after all, so she followed the other student's directions and made her way to the dorms, and finally to Zoe's bedroom. To her surprise, when she opened the door, Zoe was, indeed, there, asleep on her bed.

That was strange, but maybe, because it was her birthday, she was allowed to get out of classes for the day. That was good, Sierra thought. That meant she could help her get out of here sooner. "Hi," she waved as Zoe's eyes blinked open. "Happy Birthday."

"Sierra?" Zoe sat up, shocked. "What are you doing here?"

"I just thought I'd pop in to say Happy Birthday," she shrugged bashfully. Suddenly, she wished she'd thought to bring some kind of present. It seemed pretty lame to show up, say that, and then ask for her help, rather than giving her anything. "This place is... umm... nice?"

"You fit right in," Zoe teased.

"I-I wasn't sure what all they allowed you to have here, so I didn't know what kind of present to give you," Sierra lied. "Is there anything you need?"

Zoe's eyes lit up, although Sierra was sure that was just because of what she said next. "Well, the kitchen makes really good chocolate pudding, and I had to miss lunch." Sierra knew she loved her pudding, after all. "Could you just go sneak into the kitchen and get me some? I doubt anyone is even in there right now, and if they are, I bet they wouldn't mind."

"Sure," Sierra shrugged. How hard could it be, after all? It was just some pudding. It was the least she could do for Zoe's birthday, especially since she was going to need a favor from her once she was finished. "I'll be right back!"

"See you at dinner time," Zoe chuckled, once the door was shut. If she wasn't able to steal pudding without being caught, there was no way Sierra could, and from what the headmistress had said, she was sure she knew exactly what was going to happen once she was. Maybe this wasn't going to be such a bad birthday after all.
