What was she doing?! It was a question Matti had asked herself many times lately, yet she still hadn't come up with a good answer for it. Perhaps she was assuming that, since Valerie wanted to meet at Dr. Osswald's classroom, rather than her dorm room, maybe she was going to take it easy on her today. Maybe it was because it was a bit unseasonably warm today, and her usual hoodie would have been too much, even if it wasn't nearly as long, or baggy. Or maybe there was a part of her that was excited to think about toddling back to her own room afterwards, knowing there was a chance her shirt might have ridden up, and a hint of plastic waistband was visible between that and her jeans.

There was still time to change her mind. She could throw something else on over it. She could even text Valerie and tell her she wasn't coming, though, with all the pictures and videos the cheerleader had of her now, that was an extremely risky prospect. But Matti had already told her that she was going to have to leave earlier this week than she had last time, since she'd almost missed her weekly Dungeons and Dragons games with her friends by the time she'd gotten back to her dorm room and out of the diaper. Of course, she could have stayed in the diaper, and none of the guys would have noticed, probably, but that wasn't a risk she was willing to take. Besides, she definitely would have been too distracted to concentrate on the game if that had been the case.

But, no, she didn't do that. She grabbed her bag and, heart pounding, stepped out of her room, marching across campus, feeling more and more giddy the closer she got to her destination. When she arrived, she immediately saw that the first possibility she'd considered was not the case at all. The boards, and their respective dildos, were set up and ready for her, and there was a changing mat laid out, a thick diaper waiting for her on it.

"There you are," Valerie huffed. "You're the one who wanted us to start earlier! I ought to make you write a whole other board's worth of lines for being late!"

"B-But I'm not..." Matti frowned, glancing over at the clock. Technically, she was late, though only by a minute or so. She really didn't want to do any more lines than she had to, but it wasn't quite as scary as Valerie was making it sound, since she'd technically already done that last time, when she hadn't messed her diaper the first time she'd filled the final board. "I'm sorry," she grumbled, dropping her bag on an empty desk.

"Not very convincing," Valerie commented. "I can see why you aren't an actress. Come on, let's get started, you little brat."

Matti walked over to the changing pad, fumbling with her belt, not quite managing to get it open before she reached her destination, leaving Valerie to do it for her, which, to be honest, she'd been kind of hoping for anyway. It was so much better, having someone else take care of all of it, to make her feel even more helpless.

"And how have your grades been, young lady?" Valerie demanded as she continued to undress the girl.

"F-Fine," Matti mumbled. She had been intentionally missing a question here and there on quizzes, trying to make a start, but a lifetime of good grades made it hard to commit, until she was here, staring down all those boards, remembering what the consequences for not failing were.

Valerie raised an eyebrow. "We'll see about that, once you've finished working off your last report card." She pushed Matti down onto the diaper, taping it snugly into place, then turning to look in the bag that she had sitting next to the mat, while Matti squirmed on her back, blushing as she glanced down at herself, seeing how the hem of the shirt only barely reached the waistband of the diaper. If anyone else walked in, there was definitely no hiding it now!

And, really, she had nobody to blame for that besides herself. She felt a warmth rising in her body, though it was hard to tell if it was from shame, excitement, or both. She resisted the urge to give her diaper a squeeze, lying back, waiting for, she assumed, the lipstick.

Instead Valerie held something against Matti's inner thigh, strapping it into place, held right against the crotch of the diaper. Matti's blush deepened at the contact, and then even more when Valerie held something up. "You remember this?" she asked, showing Matti the dinosaur-shaped object she'd seen online at their last session.

"Y-Yeah," Matti nodded, eyeing the knobs on the dinosaurs back, then following the wire that came from it as it stretched downwards, to her leg, ending at the vibrator that Valerie had just strapped there. She let out a tiny squeak, but, just like with how visible she'd left her diaper, she wasn't sure what this one was from, either, how she really felt about this development.

"This should give you some encouragement," Valerie giggled, stretching the dinosaur-shaped remote to Matti's other leg, strapping it into place there, then helping Matti to her feet. Matti took a few tentative steps, face darkening any time she felt the head of the vibrator rub against her diaper, the bulk of the diaper, and the short length of the cord stretched between her legs, making it difficult to move.

"I-I can barely walk," she pouted.

"Oh, sweetie," Valerie smirked, finally producing the lipstick and applying it, "you're just a dumb baby. You don't need to worry about that. The furthest you need to walk is over to the board to start writing a stupid little diaper bimbo you are."

Matti waddled over carefully, not wanting to get all tangled up and fall, picking up the piece of chalk and stretching up, face flushing as she thought about how now, her diaper was completely exposed, totally out in the open for anyone, including Valerie's camera, to see, and there would be no denying what it was, no way to pretend that it was the shadows making her panties look like something they weren't. What had she been thinking?!

And, to make matters worse, before she was even finished with her first line, she heard the door open. She gasped, lowering herself, tugging frantically at her shirt, despite knowing it was no use, feeling a little like she was about to throw up as she turned, expecting to find Dr. Osswald there, staring at her with her diaper and vibrator.

But there was nobody. Not even Valerie was there, to her surprise. Matti frowned, taking a small step away from the board, glancing around the room to see if the cheerleader was hiding somewhere.

Where had she gone? Had she needed to use the bathroom? That was kind of embarrassing, in a way, a reminder that Valerie was allowed to just go do that whenever she wanted, while Matti was expected to use her diaper, but it was strange she'd go do it now, rather than watching Matti's punishment.

Matti's eyes drifted downwards, looking at the brontosaur-shaped remote strapped to her leg. It wasn't hard to see how it worked, with one button to turn it on, positioned in the place of the dinosaur's eye, and then a knob in the center of it to change the intensity. It would just be one press, and a twist, to try it out. It was probably a good idea, really, so she'd know what to expect.

That, and, if she was being honest, she'd been dreaming a lot about what had happened back at Ms. Emily's daycare, when she'd gotten bounced on the woman's knee. She'd never felt anything even close to that before, but she suspected this was going to be close. And now that it was there, taunting her, it was hard to imagine having to wait until she'd written a whole chalkboard full of lines when all she wanted to do was turn it on, especially now that she was alone.

Just a taste, she told herself. That was all. As she bent down to do that, however, the door opened again, sending her scrambling as quickly as she could, which wasn't very, for Dr. Osswald's desk, the only thing she had to hide behind, but, of course, it was just Valerie again.

"That's all you've gotten done?" she sneered. "Well, that's fine with me, I suppose. You're the one who wanted to leave early. It's your fault if you don't make it."

"I-I just..." Matti protested.

"I don't care," Valerie waved her off. "Get to work."

"Y-Yes, ma'am," Matti nodded, shuffling back to the board and going back to writing. There was still a sense of dread as she neared the end of the board, as she eyed the dildo waiting for her at the end, but it was vastly outweighed by the excitement she felt, knowing what else was waiting for her.

Sure enough, once she finished the last line on that board, Valerie strutted up, patting her on the head. "Good girl," she praised. "Now, kneel down for me so you can show me how good you really are, and how much you remember from last week." After Matti knelt, Valerie pushed the dino's eye.

Matti squealed in surprise and delight as the vibrator came to life, rumbling pleasantly against her diaper. "I had a feeling you'd like that," Valerie chuckled, Matti blushing in response, wishing she'd tried to hide her excitement at least a little. "Now, I want you to make a nice lipstick ring again, like last time, but you're going to keep it in your mouth until you make squirties. Do you understand?"

She gave the seat of Matti's diaper a pat, and Matti nodded. She'd wanted to get the dildos out of her mouth as soon as possible before, but if this was what she had to do to get to continue to experience the vibrator, well, it wasn't that big of a price to pay, was it?

What was she saying?! Maybe she really was a diaper bimbo, thinking like that! It was hard not to think of herself that way as she obediently opened her mouth, taking as much of the dildo inside as she could while she knelt there, diaper growing warmer and stickier as the vibrations reverberated through it. Maybe the smart little tomboy nerd she'd always considered herself to be had been a front all along, and deep down, this was what she was meant to be...

The orgasm was, she had to admit, not nearly as good as what she'd felt with Ms. Emily, but it was still better than anything that had happened since, leaving her panting and blushing as she tried to catch her breath, lying in a puddle below the chalkboard while Valerie smugly pushed the button to turn the vibrator off.

"And that was just the first level of intensity," she teased. "I was thinking we'd go up a level after each board. How about that?" Before Matti could stop herself, she felt her head nodding eagerly, saw the smile forming on Valerie's face, showing that she knew how much Matti was enjoying this, despite her weak protests, as if her moaning hadn't been enough for that anyway.

She wasn't sure she was going to be in any shape for D&D after this, especially after Valerie switched it up, making her wet her diaper during the second board, which, combined with turning the vibrator up, made for an even better orgasm. And then she made Matti poop her pants on the one after. It still wasn't as good as Ms. Emily, but it came closer than she would have thought possible, leaving her as a puddle on the floor for a few minutes.

Valerie had her finish up with a board of, 'I am an obedient little diaper bimbo,' which felt more appropriate than ever after all that, and with her diaper very well-used, starting to sag between her legs as she wrote. She was so dazed by the time it was all over, and after she'd wiped the boards clean and helped Valerie pack up the dildos, that she might have toddled out of the classroom just as she was, but, thankfully, Valerie took her over to the changing pad first.

"D-Do I get my underwear back?" Matti asked, head spinning.

"Do you think you deserve them?" Valerie countered.

Matti blushed, thinking about everything that had happened, and shook her head. "N-No, ma'am."

"I agree," Valerie smirked, taking out another diaper. Matti was embarrassed, looking at how obvious the bulge seemed under her jeans, with just her t-shirt, but a reminder of what had just happened in the classroom helped her keep things in perspective. Compared to that, toddling across campus with a bit of her diaper showing, possibly, was nothing! "Now, don't you have somewhere you needed to be?"

"I-I don't think so," Matti shook her head. She was definitely too worked up right now to even think about D&D. The boys would understand her missing a week, she was sure.

"Oh, good," Valerie said. "Then we can get you back to your room."

"We?" Matti frowned. Why would Valerie go with her all the way across campus to her room?

"I wouldn't want a poor, dumb, little baby like you to get lost," Valerie told her, taking her by the hand, picking up her bag. "Come on. You can carry that," she gestured to the bag she'd stuffed Matti's used diaper in.

As if she needed any more proof of how scrambled her brains were after everything, Matti didn't think about her own bag until they were out of the building, Valerie thankfully taking her out the back so she could dispose of the trash in the dumpster without anyone spotting it. "I-I forgot..." she protested.

"Don't worry about it," Valerie cut her off, leading her not towards her dorm, but in the opposite direction.

"Wait," Matti said. "I thought we were..."

"Don't worry about it," Valerie patted her on the bottom. "Thinking isn't your strong suit, is it?"

Valerie led her to her own dorm, up the stairs to her own room, opening the door to reveal that something had changed. Matti's bag was sitting on one of the beds, which was surrounded not by Valerie's roommate's possessions, as it had been last time Matti had been here, but with Matti's own.

"Wh-What is all this doing here?!" Matti demanded.

"Oh, you know," Valerie shrugged nonchalantly.

"No, I don't!" Matti glowered, stomping her foot. "Why is all my stuff in here?!"

"Well," Valerie said, "my roomie decided she wanted to move out, and I thought it would be a good idea to keep you closer to me, so I can keep a better eye on you, so I told her that you wanted to switch rooms. I had some of my big, strong guy friends borrow your bag at the start of your lesson today so they could get your keys out of it and move your things for you. Maybe after a few more lessons, you can thank them properly."

"B-But I don't!" Matti shook her head, ignoring that last bit for the moment, since the first was so awful. Her beloved private room! She'd wanted that so badly her first few years at college, and had barely been able to snag it this year, even, there were so few to go around. How dare Valerie make her give it up without even asking!

"That doesn't matter," Valerie shrugged. "It's not about what you want, Matti, it's what you need, and right now, I just don't think a session or two on the weekends is going to be enough to teach you everything you need to know about how to be a good little bimbo." She pinched Matti's cheeks. "We are going to have so much fun together! Or, I am, anyway." She giggled, watching Matti's face grow red. "For now, I think somebody needs some rest after her long day. She's getting grumpy!"

"I'm not grumpy!" Matti stomped her foot again. "You had no right...!"

"Fortunately, I already have you in your nighttime diaper," Valerie ignored her. "I can tell you need those. Now, grab your toothbrush and your washcloth!"

"I'm not going to bed!" Matti fumed. "The sun hasn't even gone all the way down yet!"

Valerie looked around, snatching up the basket Matti kept her bathroom supplies in with one hand, grabbing Matti by the wrist with the other, shoving her out into the hall, following her to the bathroom to hover over her, watching her like a hawk as she brushed her teeth and washed her face. Matti wasn't sure why, at first, if the girl thought she was going to try to run off, without a key and in a diaper.

Then, as she was marched back to her new room, it dawned on her why. She was making sure that Matti didn't try to use the bathroom. As early as it was, there was no way Matti would make it through the night without having to go, which would make it look like Valerie was right, and she really did need diapers at night.

"These are your PJs?" Valerie wrinkled her nose as she dug through Matti's clothes. "I guess they're not as bad as some of the rest of these. Well, we can get you something better later. I'd let you borrow some of mine, but they'd be much too big for a baby like you." She pulled the oversized soccer jersey Matti slept in out, yanking it over the girl's head, though she left the shorts that normally went with it there. Unlike the shirt she'd been wearing before, it did cover most of the diaper, at least. Not that it mattered, since she was about to be put to bed.

"I guess you missed supper, didn't you?" Valerie asked, as if she didn't know. "I guess you should have written faster. But I'm not totally heartless. I have a nice little snack for you."

She opened up her mini-fridge, taking out a bottle of milk that she slipped into the microwave, as she sorted through her own clothes, taking something out and strapping it around her waist. Matti didn't see what it was until the microwave beeped and Valerie took the bottle out, inserting it into the device she'd put on and turning around.

It was meant, Matti assumed, to hold a strap-on, and any of the dildos from the classroom would likely have fit in there, and hung between Valerie's legs. Instead, the bottle was in its place, the nipple dangling there. It wasn't so different from when Valerie had fed her a bottle at cheerleading practice, Matti told herself, but it still seemed more wrong this way, somehow.

"I-I'm not hungry," Matti told her.

"Nonsense," Valerie replied. "Don't you want to grow up to be big and strong someday? Come on, Matti, crawl over here and get your snack."

Matti groaned, but, after a moment, she lowered herself to her hands and knees, crawling across Valerie's fuzzy carpet, staring up at the girl with a pout before taking the bottle's nipple into her mouth, starting to suck it down.

"Look at that," Valerie grinned proudly. "Your lessons are paying off already! That's much better than you did the first time! I think you need a snack like this every night, don't you?" Matti shook her head, but she didn't dare stop drinking her milk, so it was easy for Valerie to pretend she hadn't seen.

By the time Matti was finished, there was definitely no chance of her getting through the night without needing to wet her diaper, especially since Valerie tucked her in right after that, milk sloshing around in her tummy. "Night-night," Valerie kissed her on the forehead. "I'll be back later."

"Y-You're not even staying?!" Matti started to sit up.

"Unlike you, I'm a big girl," Valerie told her. "I have things to do tonight. But don't get any bright ideas. I have a camera in here, watching you, and you're going to regret it if I see you out of bed, young lady."

Not only that, Matti thought once Valerie stepped out, leaving her to sulk under her covers, but Valerie hadn't even given her the key to the room yet. Sure, she could have put on some different clothes to hide her diaper, or taken it off altogether, but even if she wasn't afraid of what Valerie would do, she had nowhere to go. Valerie's old roommate had the key to Matti's old room, and Matti had no way to get back into this dorm, or this room, if she left. She could go to the D&D game, but then she'd have to explain why she was so late, and she didn't want to see how Valerie would make her regret it when she inevitably came slinking back.

She tossed and turned for a while before giving up and letting herself wet, blushing as she felt the warmth spread through her diaper. Was it wrong to think about how hot it was that Valerie was going to be able to point to this and call her a bedwetter, giving her an excuse to keep her in diapers every night? Or to be turned on by how much the cheerleader had taken over her life, making her go to bed this early on a Saturday, trapping her under the covers to pee her pants like a baby? She did want to have her old room back, yes, but it was hard not to get at least a little horny at her current situation.

In fact, she was pondering how good the camera Valerie had was, or how closely the girl was watching it, and whether or not she might be able to get away with a little naughtiness without Valerie noticing, when the door opened. She froze, fingers inches away from her soggy crotch, huddling under the covers at the sound of Valerie giggling, along with an unfamiliar voice, one much deeper.

"Oh, sorry," it said as it spotted her. Matti burrowed in deeper, cheeks burning, as the hot guy Valerie had brought in looked in her direction. "You didn't tell me..."

"Oh, it doesn't matter," Valerie told him. "I told you I had a new roomie, didn't I?"

"Well, yeah, but if I'd known she was in here..." he said.

"She's always in here," Valerie rolled her eyes. "Poor thing doesn't have any friends, and she's too anxious to go out and do things on her own, so she has nowhere to go. But she promised to stay quiet and not bother us, didn't you?"

She shot Matti a look that made it obvious what her answer should be. "Y-Yeah," she replied quietly. "I-It's fine..."

"Isn't that a little weird, though?" he asked.

"I don't know," Valerie shrugged, pushing him over to her bed, and down onto it, planting a deep kiss on his lips before glancing back at Matti with a giggle. "I think it's kinda hot."

"I-I'm not sur..." he started, only to be interrupted by another kiss.

"Give me a chance," Valerie told him. "I bet I can convince you."

All Matti could do was squirm under her covers, doing her best not to watch as they made out, but having a hard time keeping her eyes off of them, until, finally, they went to sleep.

She woke with a start, confused for a moment about where she was, though, thankfully, she stayed quiet, since she saw, a moment later, that, in her sleep, she'd kicked off most of her covers, and her PJ shirt had ridden up, leaving her wet diaper on full display. Hurriedly, she covered herself back up, peering over at Valerie's bed, seeing the girl and her boyfriend still passed out.

Her eyes flicked over to the door, wiggling nervously. She really needed to pee again, but did she dare get up and try to tip-toe out? She could maybe prop the door open for long enough to run to the bathroom and return, but she didn't want either of them to wake up and spot her. A couple times, she shifted her weight, started to sit up, only for one of them to move, making her lie back down quickly. In the end, she just let it go again, the diaper swelling, but holding it all, making her supposed bedwetting problem appear even worse.

Thankfully, Valerie's boyfriend had football practice to get to that morning, so he left bright and early, letting Valerie get Matti cleaned up, teasing her, but begrudgingly allowing her to put on real underwear afterwards. As Matti got dressed, however, she had another surprise for her.

"We're definitely going to go shopping to find you some better clothes at some point, but for now, I got you these as a moving-in present." She handed Matti a pair of tall, stiletto heels, decorated with roses and straps that would wrap around Matti's legs.

"I-I don't really..." Matti protested, for all the good it was going to do her. Valerie pulled them onto her feet, proudly winding the straps around her lower leg, then cackling as Matti tried to stand in them, and nearly fell right away.

"You'll get used to them," Valerie told her.

"No, I won't!" Matti whined. "I can't go out in these! I'm going to break my neck!"

"Here's your key," Valerie said, ignoring her. "You are to turn it in to me every night, because I don't want you running around when it's dark out unsupervised, but you can have it during the day, so I don't have to keep an eye on you every second."

Valerie ushered her out of the room, watching her stumble awkwardly in her heels down the hall to the elevator, glad that it was there, at least, since she was certain she wasn't ready to try stairs in these things. She managed to get to the cafeteria for breakfast, where, thankfully, she didn't see any of her friends, since they were probably sleeping in after a long D&D session, but, after that, she went back to the room and changed into her sneakers.

Her and Valerie's class schedules lined up so that, most days, Matti left after her, so she could put on whatever shoes she wanted, and Valerie wouldn't know until later. "I bought you those shoes," she huffed after a couple days of Matti returning in sneakers. "I expect you to wear them. I ought to throw those other shoes out!"

"You can't do that," Matti countered, glad she'd thought of this ahead of time, working out her plan of attack. "I can't go to cheerleading practice in those heels. And I have classes that are in buildings without elevators, and you know I can't handle that, either."

She thought she'd won, for once. It didn't change the fact that Valerie diapered her for bed, and tucked her in bright and early every night, nor that she made her drink a bottle from the strap-on harness before putting her to bed, but it was something.

And then, the next Saturday came around, and Valerie had another present for her. To Matti's surprise, it was another pair of shoes, though this one was almost the opposite of the heels. They were flat, and pink, with a smiling cat's face on each toe, and Velcro instead of laces. "Oh," Matti said when she opened the box, unable to hide her embarrassment at how childish they were, how girly. How pink, her least favorite color. "Thanks?"

"They're so you have something to wear for those times when the heels won't work," Valerie told her.

"Valerie!" Matti squealed, seeing where this was going. "You can't throw my other shoes away!"

"Don't worry," Valerie rolled her eyes. "I'm not going to. In fact, I'm going to let you pick what to wear today. I have some stuff to do, so I'm going to expect you to show up at Dr. Osswald's classroom on your own, on time, and dressed in whatever way you think is appropriate."

Was she being serious? She was going to leave it up to Matti? Of course, Matti was going to wear her own sneakers! She had no doubt that dressing appropriately would mean wearing a diaper, and it was bad enough to have to walk out of the dorm in one of those, although this time, she went back to wearing her hoodie instead of a t-shirt. She was definitely going to wear normal shoes to go with it.

She had no reason to think anything was wrong until she sat down to put her shoes on. She thought nothing of it as she grabbed the laces, starting to wind them around each other, until, suddenly, she felt a warmth in her pants. She gasped, hands shooting to the crotch of her diaper, blushing. What had happened?! Her bladder hadn't been empty, of course, since she had no doubt Valerie was going to expect her to wet her diaper for one of the sets of lines, but she hadn't needed to go that badly!

Thankfully, it was only a squirt, just enough for her to feel. It worried her, obviously, but it wasn't the end of the world. It might not even have been enough for anyone to see, even if she'd been in big girl undies! It was no big deal.

But then she tried to tie her shoes again, and her bladder let go completely. She gasped, struggling to make the flow stop, but it just kept going, pouring out of her and into the waiting padding. "No!" she squeaked in surprise. This was a full-blown accident, unlike anything she'd ever experienced before, at least in her adult life, and the sense of helplessness that washed over her as she realized that was palpable. She was peeing her pants, and there was absolutely nothing she could do about it!

"Aww, man," she groaned, looking down at herself. What was she going to do now?! She could grab a bottle of water from Valerie's mini-fridge and try to guzzle that down, but it still might take a bit for her bladder to fill back up. And if she couldn't wet herself on command, she might be stuck on her knees after that board for quite a while. Then again, if she had the vibrator running the whole time, that might not be all bad...

She blushed, shaking her head. Maybe she could explain things to Valerie, and she'd understand. She'd probably be thrilled to hear that Matti had wet herself uncontrollably. Then again, seeing as she'd been wide awake, it might also give her an excuse to make her wear diapers during the day, too, and Matti didn't want that. Did she?

Matti wasn't sure if she should change her diaper or not now, if she wanted to go across campus this way, the padding warm and swollen between her thighs. After a minute or two of deliberation, she decided that it was fine, and went back to her shoes one more time.

She almost got the laces twisted around one another before she heard herself grunt, felt the warm mush begin to push out into the seat of her diaper. "No, no no!" she shook her head in horror. What was going on?! She definitely hadn't needed to poop this urgently! But here it was, oozing out into her pants, slowly but surely, and, like her last accident, her body refused her every attempt to slow it, or halt it.

She put the Velcro sneakers on after that, if only to try to appease Valerie. She definitely couldn't change, either, as humiliating as it was to trudge across campus with a wet, messy diaper under her pants. It didn't matter what she did, she wasn't going to be able to mess herself again for a while, far longer than she was willing to spend with her mouth wrapped around the dildo, waiting. She had to throw herself on Valerie's mercy, and show her that she wasn't trying to get out of using her diapers.

"Oh, Matti," Valerie shook her head when the girl arrived at the classroom and slipped out of her jeans. "What happened?"

"I-I don't know!" Matti sniffed. "I-I was just tying my shoes, and..."

"Really?" Valerie smirked. "Did you really have to think so hard about how to tie your shoes that you forgot how not to use your diapie? Are you really that stupid already?"

There was something about the way she said it that made it clear that she knew more than she was letting on. Matti blushed, squirming in her used diaper. "Wh-What did you do?"

"Me?" Valerie held her hand to her chest. "Nothing! Those nice little nursery rhymes I've been playing for you at bedtime, though?"

"Y-You hypnotized me?!" Matti squealed, her mind reeling. She wasn't even sure she would have believed hypnosis was real before this, but now, her diaper was full of the evidence.

"I really didn't think it would work this quickly," Valerie said. "You must be extra susceptible... That, or you must really want this, deep down. Either way, now that I've seen how easy it is, I could have all kinds of fun with you."

Matti swallowed, staring up at the cheerleader, the sense of helplessness she'd felt when she'd messed her diaper nothing compared to this, to knowing that she was completely at Valerie's mercy, that the girl could, and had already been, playing with her mind, and Matti hadn't even known.

"You didn't leave me any choice," Valerie shrugged. "You wouldn't wear your shoes like a good girl, so I made it so that, if you try to tie your shoelaces..." She gave the back of Matti's diaper a swat. "Well, I think you know. But I've give you two nice options that don't need that at all. Or you could always ask a grown-up to tie your shoes for you."

She laughed at the look on Matti's face as she started to strap the vibrator to her leg. "Don't worry, though. I'll take it easy on you today. Your little accidents can count as you using your diapers for your lines. I won't make you do it again."

In fact, she had Matti start with, 'I am a messy little diaper bimbo,' which was true from the moment she started to write the words. She was so much of a bimbo, in fact, that she couldn't even tie her shoes on her own anymore! That was something six year olds could do! And she was totally incapable of it now, at least without having a huge accident!

And this, she suspected, was only the beginning. Now that Valerie was her roommate, and had plenty of access to her, and control over her, who knew what she was going to do to her next?! All Matti knew was that, as humiliating as it was, she couldn't wait to finish writing her lines on this board, even if it meant spending some quality time being taught her 'lessons'. It also meant she'd get her vibrator turned on, and, as mortifying as this whole thing was, it also made her desperate to feel that again, so she could fully appreciate what she was becoming, whether she liked it or not. And, as incredible as the orgasm felt when it finally happened, it was hard to deny that at least part of her definitely did like it, no matter how much she might try to pretend otherwise.
