The Most Important Lesson

Previous Chapter

Fluttershy didn’t think this counted as a lesson.

Thick straps bound her. Arms pulled tightly against her chest, mitted hands able to touch her cheeks and not much else. Her heels dug into her padded rump, the bindings on her legs forcing her to kneel constantly.

Eris pulled the last strap tight before buckling it in place, ensuring Fluttershy’s elbows wouldn’t be leaving her sides anytime soon. She bit down on the pacifier she somehow hadn’t spat out yet, brow furrowing.

“There we go,” her teacher stepped back to admire her handiwork. “Not too tight, baby?”

Heat rose under her cheeks. Fluttershy stammered her way around the rubber bulb in her mouth. “I… uh, um… Why do I hafta wear dis again?”

Eris booped her nose. “Well how else are you going to get the real baby experience?”

Fluttershy’s brow furrowed. She doubted the “real baby experience” involved bondage. “Um…”

“How else can you get the feeling of true helplessness?” Eris asked. Her wry smile alone reduced Fluttershy to that state. “Now you’re completely dependent on your Nana, just like a real baby.”

“Okay…” Fluttershy didn’t have much resistance to give either way. She rolled on her butt, sinking into the thick padding even further as she tried to get used to her new restrictions. The bindings left very little wiggle room. She could writhe around, but her arms were staying put, and her legs doubly so.

But the worst part was the straps running over her chest. One above, another below her breasts. They squeezed tightly, almost pushing her boobs out. Fluttershy already wasn’t fond of their size but now they look massive.

Maybe Ms. Eris will like it… A thought slipped by her defenses. Her privates felt hot at the thought. As did her face.

“Okay, sweetie.” Ms. Eris tilted Fluttershy back into crawl mode. Her diapered rear pointed skyward. “It’s been a little while since you ate. Let’s check on your diapee.”

“W-What?” Fluttershy bit down to avoid dropping her pacifier. “Bu’ I didn’ go!”

Buttons popped off, her diaper all but gasping for air with its newfound freedom.

“I know, I know,” Ms. Eris assured her. “And I know we’ve covered this lesson already, but I really must stress it’s importance.” Her hand dove into the padding, finger’s curling to grip the crinkly plastic. Ms. Eris was stressing something alright. Fluttershy nearly moaned again. “Babies won’t always cry when they’ve had an accident. You have to be vigilant.”

Fluttershy was holding her breath, scrunching her features, and hoping her face wasn’t too red.

Eris dug deep into the diaper, for far longer than seemingly necessary when she knew the answer. It was merciful and disappointing when her hand finally left. At least Fluttershy let herself breathe again.

“No accidents for you, little one.” Her achievement earned her a pat on the head. “Good job, sweetie!”

Fluttershy felt like pouting, but Ms. Eris wouldn’t see it with her face practically in the carpet. It was hardly worth praise!

“Now, why don’t we give you a chance to play for a bit like this.” Eris hoisted her up, putting them face to face again.

Fluttershy’s blush actually didn’t engulf her for once. She was actually starting to get used to being in Ms. Eris’ presence. And, barring the diapers, it was nice.

But the threat of returning to the playpen was far less so.

“Mmm…” Fluttershy whined.

“Oh come now, sweetie. I’m not going to leave you alone again.” Eris rubbed her nose against Fluttershy’s. “No no no! Not my little cutie.”

If she was trying to bring back Fluttershy’s blush, she succeeded.

“How about something more exciting than boring old blocks?” Eris bounced Fluttershy in her arms, turning the girl around to face the room. Her teacher strutted right passed the play pen to her relief. But then her eyes settled on the rocking horse, putting an end to that.

She’d barely paid much attention to it before. It had been just another toy in a room full of them. Now with each step closer she found herself dreading the sight. “U-Uhm…”

“Wanna ride the horsey, Shy-Shy?” Eris grabbed her wrist, forcing her to wave at it. “Won’t that be fun?”

Fluttershy wasn’t sure what kind of lesson this was supposed to be. Could she assume this meant all babies hated having their playtime micromanaged?

“Come on, let’s giddy up!” Eris insisted, no answer necessary. It didn’t matter, because she wouldn’t have gone for “no” anyway.

Eris plopped Fluttershy onto the horse. Her padding leaped into her crotch, forcing a whimper out of the poor girl. Eris leaned her forward so her bound hands could try and get a grip on the handlebars. It forced her rear into the air, and her privates even deeper into the diaper. Fluttershy was sweating, biting down hard on her pacifier.

“And off we go!” Eris gave the exposed butt a good smack.

Fluttershy “Eeep”ed. Not from pain, there was no way that could’ve hurt her with all her padding. But the sheer surprise of Ms. Eris basically spanking her was enough to make her heart skip a beat.

The rocking horse flew forward. Fluttershy hung onto the handlebars for dear life. She wasn’t prepared when the horse lurched back, and her smothered privates got another dose of padding.

“Mmmph~” She cried out. She’d lost count of how many times today she’d been teased. Too many not to have relief, according to her libido. As the speed of the rocking horse picked up, Fluttershy considered grinding against the wooden saddle.

Wha-What am I thinking?! She shook her head, jerked forward by the horse’s momentum. I can’t do that! Not with Ms. Eris watching me!

And for a moment, the threat of a voyuer was the only thing Fluttershy found disagreeable about using a child’s toy to masturbate in her diaper. It wasn’t until the horse came back around and she compressed her padding again that Fluttershy realized how depraved her thoughts sounded.

What is wrong with me?

She tried to focus on anything else. How tight her binds felt, the growing pressure in her bowels, the feeling of suckling on her pacifier, the— Wait, what?!

She hadn’t noticed before, but the creeping pressure in her hips was hard to ignore now. Fluttershy’s eyes went wide with sudden panic. She needed to go to the bathroom, but she…

Her diaper crinkled as it bounced back into the rocking horse’s saddle, as if to remind her she was wearing a bathroom.

Whimpering, Fluttershy clenched her cheeks and tried to ignore the mounting urge. But the constant back and forth motion was doing her no favors. The same could be said about just being aware. Just knowing she had to poop now made it pretty hard to ignore. Especially given her situation.

Finally, she started grunting into her pacifier. “Mmm! Mmm-mmm-mmph!”

Noticing her urgent tone, Ms. Eris circled around and popped the rubber bulb out from her lips. “Yes, dearie?”

“I-I…” Reservations welled within her. She mumbled out the rest. “Ineedausethebathroom.”

Eris cocked an eyebrow. “What was that sweetie?”

“I need… tousethebathroom.”

“One more time, Shy-Shy?” Eris cupped a hand to her ear and leaned in. Surely she could guess by now, right? Why make her do this?

“I need to use the bathroom!” Fluttershy whimpered out, finally at an audible level. She held back her bowels and her tear ducts all at once. This was the most humiliated she’d been all day, but her concern was too real to ignore. With the binds Ms. Eris had put her in, there’s no way she’d make it to the bathroom. She had to ask for help.

“Well why didn’t you say so, sweetie?” Eris steadied the rocking horse with a hand, finally putting an end to the unwanted playtime. “Let’s take care of that, shall we?”

Fluttershy breathed a sigh of relief. Her diaper crinkled noisily as Ms. Eris lifted her up. She flinched when her teacher put one hand under the padding to hold her, nearly dropping her load in shock right then. But she still held it back, no matter how difficult it was to clench her cheeks with the padding on. She just had to last a little longer.

Ms. Eris put her down not a moment later. Fluttershy stretched against the straps holding her bound. It’d been brief, and she would not miss them.

Then, to her surprise, Ms. Eris positioned her head down and her padded rear towards the ceiling. Her teacher made no move to take off the straps.

Ice entered her veins. “U-Uh, M-Ms. Eris…” A harsher glare than expected. “N-Nana, what are you doing?”

“Just helping you get in position.” Ms. Eris gave Fluttershy’s diapered rump a pat. “It’s much easier to go this way, isn’t it?”

Go? Oh no… “Y-You don’t mean—” She tried to push herself up, but Ms. Eris put a gentle, yet firm, hand on her back. “B-But—”

“Fluttershy, perhaps I wasn’t clear when I spoke earlier.” Ms. Eris’ tone was definitely more “teacher” than “mother” right now. “When I said I wanted you to see what it was like to be a baby, I meant you’d be getting the full experience.”

“N-No…” Fluttershy begged. Tears finally did manage to escape her, but she still held back her much needed potty break. Though the pressure was mounting. “Wait, I don’t want to—”

“Shhh…” Ms. Eris stroked Fluttershy’s hair longingly. “It’s alright, sweetie, just let it out. This is what babies like you do.”

“I’m not a baby!” Fluttershy whined. She squirmed against her restraints, but they wouldn’t budge. “I’m eighteen! I can use a toilet. Please just let me—”

“Shhhh…” Eris sat all the way down, and brought Fluttershy’s head to rest in her lap. “There’s no reason to be embarrassed.”

A veritable mudslide pushed against Fluttershy’s clenched cheeks. Her last line of defense was showing cracks. “No reason—” Fluttershy’s face grew hot. “Of course there is!” Blinking through tears, she looked up at her teacher. “Please, Ms. Eris…”

“It’s okay, honey. Nana’s here.”

Mortified, Fluttershy realized there was no way out of this. Nature was calling, and Fluttershy’s teacher was insisting she pick up the phone. Burying her face in Ms. Eris’ lap, Fluttershy whimpered. A loud fart came from her skyward rear, signaling what was to come.

With a loud cry, Fluttershy pooped herself.

A messy log pushed its way into her diaper. It smacked against soft walls, sliding down to the bottom of the padding. Another was spilling out before it even settled.

Fluttershy grabbed at Ms. Eris’ legs as tightly as her mitts would allow, sobbing as more mush emptied out of her. Even as the gross, slimy warmth gushed across her backside, the relief from finally letting it all out actually felt good. And she hated that.

Ms. Eris held her gently, stroking the back of her head and letting the poor girl cry. From her position, she must’ve had a great view of the browning diaper. She leered at the way it bulged and sagged the more Fluttershy messed herself.

Every agonizing second of Fluttershy’s accident felt like it stretched on and on and on. By the time she’d filled her diaper to the brim, she would’ve sworn she’d been messing herself for hours. Days even.

Sobs wracked her body until the mush finally settled, and then some. Gone was the relief that came with using the bathroom; now she just had the sensation of filth against her butt, and the ungodly scent wafting through the air.

“Such a good girl,” Ms. Eris whispered, her stroking slowed, but didn’t stop. “You ate a big breakfast, just like I told you to, didn’t you?”

Through spine-shivering whimpers, Fluttershy managed to nod into her teacher’s lap. “Uh-huh…” She sniffled. And boy did she regret it now.

“Aww, good girl.” The positive reinforcement wasn’t helping. Fluttershy just sobbed again. “Such a brave little stinker, filling her diaper just for Nana Eris.”

Fluttershy finally lifted her head from her teacher’s lap, eyes too blurry to see anything. She’d had enough of these baby lessons now. “C-C-Can…” she sniffled. “I-I want…”

“What’s that sweetie?” Ms. Eris helped hoist her up. The mess squelched and Fluttershy winced. “Do you want a changie?”

That wasn’t quite it, but it was a close second. Fluttershy just nodded. “Mmmhmm.”

“Well… about that…”

Fluttershy’s heart seized. She didn’t like that tone.

Ms. Eris offered a kind, if apologetic smile. “I think it would do you some good to wait just a bit before we get you out of that messy diapee of yours, sweetie.”

“W-Wha-What?” Fluttershy choked out.

Ms. Eris gave her a pat on the head. “It’ll be a good learning opportunity, don’t you think?”

“N—Mmph!” Fluttershy’s protest were pacified. Ms. Eris pushed a familiar rubber bulb into her mouth, keeping a finger on the plastic guard to lock it in place.

“If you spend a little time in a dirty diaper, then you’ll really understand what it’s like to be a baby that isn’t properly cared for.” Her smile then could melt hearts. It certainly did a number on Fluttershy’s.

But the girl still whimpered into her pacifier. She already had a pretty good idea of what it was like to be a baby in poor care. She didn’t want to spend who knows how long humoring Ms. Eris on this. Fluttershy wanted out of this dirty diaper!

The warm mush sticking to her rear wasn’t even the worst part of her predicament. That dishonor went to her privates, who, despite being trapped in a diaper with her mudslide, still hadn’t calmed down.

She could feel them tingling even now. The threat of being swallowed by the mush in the seat of her diaper did nothing to deter them. After a morning of nothing but teasing from Ms. Eris, they refused to be ignored any longer. Even if she tried.

“Now, you’ve played by yourself, but why don’t you see what a caretaker playing with her baby is like.” Eris got on her feet and picked Fluttershy up. The student whimpered as her messy diaper shifted with each movement.

Eris wrapped one arm around Fluttershy’s back, the other holding up her thighs. The position compressed Fluttershy’s diaper ever so slightly. It was enough to make her sniffle.

They made their way over to a stool in the corner, sitting down once more after just barely getting up. Ms. Eris shifted her hold on her student, legs moving beneath her. Soon, only hands under her armpits supported Fluttershy.

“Alright, little one.” Ms. Eris grinned wickedly. “Let’s play.”

“Pway wha—EEEP!” Fluttershy dropped right onto her teacher’s knee. A shudder ripped through her spine. The messy mush in the seat of her diaper suddenly went everywhere but the seat. “Mah—Ms. Ewis!”

“Time for bouncies!” And that was Fluttershy’s only warning.

Ms. Eris’ knee dropped out from under her diaper. Only her teacher’s arms, lightly gripping her shoulders, kept her steady, but they did nothing to stop her fall. Fluttershy’s messy crotch splattered right down onto her teachers thigh below.

“MMMPH!” Fluttershy bit down on her pacifier. The warm and dirty padding surged back into her. No sooner did the sensation begin before it intensified. Ms. Eris was bringing her leg back up, pushing the diaper even further into Fluttershy’s privates. “MMMPH!”

She was hot, horny. Her face broke out in a fiery blush and a cold sweat. She chewed her pacifier to fight back another moan. She could feel her slick, desperate privates smacking into the plush interior. It drove her crazy.

“Annnnd again!” Ms. Eris had no mercy. She bounced her student on her leg again, forcing another desperate moan from her.

Fluttershy snorted through her nose. As she came up again, she struggled at her binds. She couldn’t take this kind of treatment anymore. Screw her lesson and screw her feelings! If she didn’t get out of this soon she’d… she’d….

“Onnnne more time!” Another bounce. Fluttershy squealed into her pacifier.

It was so wrong, yet it felt so right.

Her diaper squished with each bounce. Her struggles faded, worthless. She looked to the ceiling and bit down hard on the rubber bulb in her mouth. Each bounce now sent waves of pleasure through her. But they could only get her frustratingly close to the edge. No matter what, some part of her was just too disgusted. It refused to let her cum.

“Aww, does baby like bouncies?” Ms. Eris did it again, earning a muffled moan for her answer. “I think she does!”

“Mmmph-mmm-mmrr…” Fluttershy whined. She felt like she was going insane. Didn’t Ms. Eris see what she was doing to her? Surely she hadn’t forgotten how messy Fluttershy was; the rotten odor wouldn’t let either of them. So why did she insist on it?

Fluttershy pulled her eyes from the ceiling, hoping a plea from the enlarged diner saucers would be enough to get her teacher to stop. But one look at Ms. Eris sent a shiver down her spine.

She looked hungry.

The wry smile on her face. The glint of lust in her eyes. The sultry way she stared back at her pupil.

The bouncing stopped, one last horny burst on the way down. Fluttershy couldn’t look away from her teacher yet. And Ms. Eris wasn’t about to give her the chance.

She reached around, grabbing a fistful of pink hair from the back of Fluttershy’s head. With her other hand, she drifted two fingers near the girl’s crotch, and pressed them into the padding.

“Mmmm…” Fluttershy shifted her body as much as she could, instinctively trying to grind against her teacher’s leg. The fog of her own horniness obscuring how wrong this all should be.

“Good little girl.” Ms. Eris’ voice was a husky whisper. Her fingers moved in a circular motion around Fluttershy’s privates. “Very good girl.”

A whimper slipped out. It lasted only a second, but it was clear what Fluttershy meant by it. She was pleading for more.

Ms. Eris’ hand came up, and ripped the pacifier from her students mouth. She forced her face in close and smashed their lips together in an embrace.

Sirens and fireworks went off in Fluttershy’s mind. A joyous chorus of angels sang. She was kissing Ms. Eris!

Her diaper squished. Her privates cried out needily. Ms. Eris seemed to hear them, bouncing her leg again, but with patience this time.

Privates burning, Fluttershy leaned desperately into the kiss, even as Ms. Eris pulled her hair in the other direction. Her teacher’s free hand explored her chest, pinching at her nipple through the onesie. Fluttershy’s own hands wiggled desperately, hoping to do the same.

They kissed and bounced together, needing to come up for air many times due to the stink. But eventually, Ms. Eris broke away for something else.

She ripped off her tank top, no bra underneath. Fluttershy gasped in shame, as suddenly her teacher’s boobies were flying free before her. That feeling only lasted a second, even if the blush stayed. Ms. Eris’ hand reached her head again, forcing her to keep looking.

And then nudging her to get closer.

Fluttershy’s eyes widened as she realized what her teacher wanted to do. She opened her mouth, and was practically pushed into one of the pink nipples awaiting her.

“Ah~” Ms. Eris sighed as Fluttershy’s lips kissed her breast. “Yes!”

“Mmm…” Fluttershy closed her eyes. Her tongue poked at her teacher’s nipple, and she gingerly bit down.

The bouncing started up again, a reward for her good behavior. But to be honest, what felt even better was hearing her teacher moan.

“There we go, Fluttershy,” Ms. Eris cried out. “Good girl. Good girl.” She stroked the back of her students head, and with her other hand grabbed the mushy seat of the diaper.

“MMM!” Fluttershy bit down harder, a jolt of gross pleasure gripping her. Ms. Eris cried out. She was finally blushing.

She kept working away at her teacher’s chest, trading breasts every so often. She could press her face as deeply into them as she wanted, rewarded each time by a squeeze of her diaper.

The desperate urge from her privates only grew. She was so close to climaxing, and inching closer to it with each minute that ticked past, yet something still held her back from the full experience. Try as she might, in a situation she would’ve been too embarrassed to even dream about, Fluttershy couldn’t quite cum.

Her nasty diaper squished up against her, the two of them locked together. That had to be it. As horny as it made her, it was easily the grossest thing imaginable. Not exactly one of her wildest fantasies when she thought about being alone with Ms. Eris.

But it only took a single second to turn that around.

Her teacher tackled her to the ground, pouncing on top of her. With Fluttershy’s binds, she didn’t need to hold her down. Instead, she grabbed Fluttershy’s diaper with a vice-like grip, thumb pressing into parts of the poor girl’s nethers she didn’t even know were there. Ms. Eris leaned in close to her ear and whispered, “now cum for Mommy,” before she locked lips with Fluttershy again for their most passionate kiss yet.

And Fluttershy finally came.

Her whole body radiated heat. She stiffened, then relaxed against her bindings. Eyes rolled back in her head. Ms. Eris’ lips on hers. Ms. Eris’ chest on hers. And Ms. Eris’ hand in her diaper.

The best feeling Fluttershy had ever experienced in her entire life.

Their kiss ended with a wet smack. The poor girl left pooped in more ways than one. She laid on her back, breathing heavily, her teacher leaning over her.

Ms. Eris chuckled. “That,” she said. “Is not something you do with babies.” She leaned in and kissed Fluttershy’s cheek. “But it is something I’d like to do with you again.”

Fluttershy was a mess. She couldn’t even respond, except with a weak nod.

Eris’ hand traced Fluttershy’s figure, from the side of her chest down to her hips and her dirty, dirty rear. “I have a feeling with a few more after school sessions like these, you’ll pass my class with flying colors.”

“Uh-huh…” Fluttershy gasped. Cognitive function had not yet returned. Her lips, both of them, were still buzzing.

“I can see you need a little time. How about we pick up our little study session after you’ve had a nap, sweetie?”

Fluttershy wanted to ask for a change first. Even in the high that was this afterglow, the sticky mush on her backside was still unpleasant. But she couldn’t muster the words before Ms. Eris picked her up again. And being held with her face pressed against her teacher’s chest killed any chance of protest. Fluttershy just leaned against them and sighed happily.

She was laid back down in the crib, sinking into the mattress. The pacifier found its way back between her lips, and she didn’t fight it. Nothing was going to ruin the feelings still pulsing through her body. She suckled happily, like the good little girl she was.

“Sleep tight, honey.” Ms. Eris blew her a kiss. “Mama’s got more plans for you when naptime’s over.”

“Yay…” she managed a weak, but enthusiastic response. Her eyes could barely stay open, so she didn’t fight them. It was exhausting being Ms. Eris’ baby, but so, so worth it in the end.

Fluttershy closed her eyes, and dared to dream about what her teacher would do to her next.

All of a sudden, she really loved the childcare class.
