Tartarus was an absolutely horrible place. What was depicted in the book is canonically confirmed to be a shadow of what it's really like. The terrain, the shapes, the atmosphere-all creations of the dark god's whims. The monsters that lived there thrived on the pit's resources, growing stronger and more powerful in the name of half-blood flesh. Any demigod that found themselves in Tartarus was certainly in for a hellish experience.

Percy and Annabeth were no different.

After so much suffering already, they managed to find themselves in the company of Bob the Titan, formerly Iapetus, but a dip in the Lethe had made him forget his former life of violence and evil. For the most part. While the evil part was mostly gone, the violence part was certainly still there, as proven by his performance during this nightmarish battle in the pit.

We are the arai, a disembodied voice echoed through the skeletal trees of Tartarus.

Surrounding the grouped up trio of Percy, Annabeth, and Bob were demonic grandmothers. Their hair was all kinds of frizzy and old, their faces withered and wrinkled, their eyes solid black, their expressions frozen, their teeth pointed, their dresses tattered and filthy, their hands adorned with talons, and bat-like wings sprouted from between their shoulder blades.

We are the spirits that carry the curses of the dead. Their dying wishes are ours to inflict. And you, Percy Jackson, have incurred many curses.

The voice of the arai came everywhere. It flowed smoothly, genderless, pitchless, toneless. Percy couldn't tell if the voice was coming from one of the monsters, all of them at once, or if they had a collective consciousness and could talk through the air. Or maybe it was telepathy. He didn't know, but he did know that he was itching for some action. All this wandering around in the dark, barely able to breathe, nothing to eat, still riddled with ADHD-Percy wanted something to swing his sword at. A change of pace.

He wanted to be on the offensive, and now he was getting his wish.

"Yeah, yeah," the son of Poseidon dismissed the threat of the arai. "Are you just going to stand there and talk, or are you going to come at us and die like every other monster?"

The arai laughed. You have no idea what you're dealing with, boy. We will show you.

Percy muttered the battle plan. "Bob, take the uglies on the left. Annabeth, the right. I'll take everything else."

The first demon attacked. Percy swung Riptide, and immediately became aware of how flawed his plan was. The monster turned to dust like any other monster, but Percy dropped to his knee with a wheeze, stabbing his sword into the ground for balance.

"Percy!" Annabeth cried.

She ran to his side, and gasped at what she saw. There was a literal hole going through Percy's ribcage. If she had to guess, it literally went through his whole body, through his lungs. Plenty of blood was leaking through the holes.

The curse of Geryon, the arai said. Shot through the side with an arrow fired by Percy and guided by Hera. His dying wish was for the pain of his demise to be inflicted upon you, Percy. Please, do kill again. We have so many curses to share with you.

Another attacked, but Annabeth reacted on reflex. The monster got within range and was grabbed by the blonde, flipped over her shoulder, and got to experience the strength of a demigod when Annabeth drove her elbow into its neck so hard it died. And with its death, came its curse.

Annabeth screamed, her hands flailing wildly. "I can't see!"

Percy looked and gasped. Annabeth's grey eyes were whited over, the pupil and grey iris now cloudy. The pain in his chest had lessened, and he could feel the holes were gone, but blood he'd lost was still gone.

The curse of Polyphemus. You called yourself Nobody. The same Nobody that left him blind. Now you feel his curse, Annabeth Chase. You will be blind.

Rage boiled through Percy at seeing his girlfriend like this. Unable to see, unable to defend herself. More arai swooped in, and Percy lunged. However, Bob swung his broom and wiped out the whole line. More arai attacked, but Bob was on the ball, sweeping and swinging his humongous broom with lethal force and precision.

Percy stared in horror, sure that Bob would come down with dozens of curses and probably be killed under the strain, pain, and magic of the curses, but the Titan stood tall. Maybe he was too powerful for the arai's magic?

"Bob, you okay? No curses?"

"No curses for Bob!" the Titan declared happily.

Of course not, the arai said, almost sounding like they were laughing. You are cursed enough as it is, Titan of the West. Deceived by those you call friend. The mighty Iapetus, left alone in the palace of Hades to sweep his floors and clean his toilets, your memory taken from you by the one you defend.

Percy's heart practically plummeted.

Bob's confidence ebbed away. "What? Percy deceives me?"

Yes. You are Iapetus the Titan, but a battle with Percy in the past resulted in you falling into the River Lethe. Your memory is gone, your glory and identity taken. And the one responsible has said nothing. He has not even behaved like a true friend.

Bob turned and stared at Percy. Annabeth was still blind, on her knees and trembling as she looked in some direction with her milky eyes. Percy was holding onto her, also on his knees. He stared back at Bob.

"Bob, listen to me," he said. "You are a good Titan. There are lots of bad Titans, but you're one of the good ones. I'm sorry I never came to visit you like a friend is supposed to do. I-"

"Like a friend," Bob said hollowly. "The other is a friend."

Percy's brow furrowed. "The other?"

"Nico. He visited Bob. Told Bob about Percy Jackson. A friend."

"Percy, what's the escape plan?" Annabeth whispered frantically.

"Uh, hold onto me."

Yes, Iapetus. Nico is a friend. Percy is not. Percy is a liar. Let us have him. Let us give him our curses.

The arai didn't wait for an answer. They just attacked in a swarm. Bob stood there as the demons flew past him, and he stared at Percy's back as he grabbed Annabeth's arm and went running through the darkness of Tartarus.

Percy did feel bad about Bob, but he had bigger things to worry about right now, like the army of demon grannies that were either going to kill him, or he would kill them and receive some kind of awful curse. As he ran through the dead forest, Percy slashed the trees, sending them toppling and crushing any arai that had gotten too close.

For a moment, it seemed they might just outrun the monsters, even with Annabeth blind and unable to see where she was going. But that moment ended when the darkness of Tartarus got even darker, and Percy came to a stop in order to avoid running right off the edge of the cliff and into the dark chasm. The arai swarmed around, some hovering, some flying in lazy circles, and most of them were arrayed before Percy in a thick crescent formation.

He and Annabeth were surrounded.

Percy swallowed. He stepped forward and raised Riptide. "Well? What are you waiting for? Come and get it!"

Annabeth sank to her knees since she couldn't see and didn't want to do anything in fear of something happening to her.

The arai's strange voice echoed with laughter. As you wish.

Percy heard the sound of swooping from behind, and so he twisted, swinging Riptide in an arc that vaporized the offending monster. The curse struck instantly, and it left Percy gasping in shock, staring at his crotch in surprise and horror.

Warm liquid was pouring out of him-not blood-instantly soaking through his underwear to cause his jeans to warm and cling to the skin of his legs as the denim became drenched in...pee. He was peeing his pants. For the first time since he was nine, he was having a tinkle accident.

Physically, that didn't even make sense since he was dehydrated and running on nothing but Phlegathon water, which wasn't even water. How in the world was there enough urine in his bladder to warrant this kind of flood? Percy was so bewildered he couldn't be mad, not even when his socks and shoes were soaked and a large puddle formed around him.

But one look at Annabeth brought forth new fury to Percy. She was looking at her own crotch with the same expression he had worn, and for the same reason. She had just wet her pants too. Glistening on the ground around her was a light yellow puddle that was steadily spreading.

Tears started welling in Annabeth's blind eyes.

Salt was poured in the wound when the arai laughed at the duo's wet humiliation.

"Okay, who did I kill whose curse was I want them to pee their pants?" Percy demanded.

One of the many hundreds of monsters you've slain was the unsatisfactory answer.

Another demon attacked, and just like the others before it, it was destroyed by Riptide. And just like the others before it, it released its curse.

Percy's world came to a grinding halt when a something big, warm, and mushy suddenly rushed out of him. It was firm enough to push his pants and underwear away from his butt. It couldn't be...he didn't...he couldn't...there was no way...Percy gingerly reached behind him and pushed against the offending mound, and he jumped at the feeling. He had.

For the first time in his conscious memory, he had pooped his pants. He couldn't recall a time ever in his past, not when he was in preschool, kindergarten, elementary school, any daycare, or any instance whatsoever of him having a poopy accident. And here he was, in Tartarus, fighting for his and Annabeth's lives, with a a huge, stinky load in his underwear...Annabeth.

With a slack jaw, Percy looked over at Annabeth, recalling how when he'd peed his pants, she had also peed her pants. Annabeth had a shocked expression on her face, her blank eyes easily conveying that much, hand reaching for the large protrusion in the seat of her shorts that had stained the material brown. Just like her boyfriend, Annabeth had pooped herself.

Percy literally could not believe this was happening. Here they were, in Tartarus, fighting monsters that had just cursed them to pee and poop themselves like little kids. It couldn't be real, it just couldn't! But it was made plainly clear when one of the arai casually hopped up to Percy and shoved him. He was so stunned by current events that he put up no fight and was late in his reactions.

He groaned when he landed on his butt and felt the yucky mess spread and squish in his underwear.

"Percy?" Annabeth's voice cracked. "What's going on? Are you okay? Did you also...did you poop your pants too?"

"Yeah," Percy breathed.

"Oh, gods."

Percy got back to his feet, ignoring the squishy mess he'd made of himself. It was time to get serious.

"Alright, you disgusting freaks, round two!"

The demons laughed, and Percy felt this might be a huge mistake. But his pants were wet and messy. Annabeth's pants were wet and messy. And he was just fed up with it all. When the arai attacked, Percy swung his sword.

And after he killed one of the monsters, amongst all the curses that assaulted him, one particular curse hit and everything changed.

PJOABDL

Percy dropped to his hands and knees, Riptide discarded, and every curse that ailed him vanished, except for the one that currently affected him. The light in Percy's eyes was off. It was a happy and innocent light, free of worry and any feelings of pain and discomfort. His eyes shown with childlike wonder and curiosity. He seemingly no longer cared that his pants were glued to his legs by warm urine, or that a stinky mess coated his backside.

"Gah-gah," Percy said.

"Woo-woo-dah-uh."

Percy crawled on his hands and knees, turning around to face the speaker. His babyish eyes lit up when he saw a familiar face.

"Ah-beh, Ah-beh!" he chirped, unable to say "Annabeth" clearly.

Just like Percy, Annabeth was clear of all curses except for the one that rendered her infantile. She could see again, was crawling, her eyes shown with the same light that Percy's did, and just like him, she didn't care at all that her pants were wet and full of poop. The mighty daughter of Athena crawled forward in her poopy shorts, planting a big, wet, sloppy kiss on Percy's cheek.

He made a happy noise at the contact.

Aren't you two just precious? the arai laughed at the powerful heroes, reduced to baby-minded teenagers that desperately needed their underwear changed. We will take you to Mother. Your new lives begin now.

Two arai swooped down and scooped up Percy and Annabeth. They squealed in delight at being carried through the air. The two demons holding the half-bloods had their noses wrinkled and were making conscious effort to breathe through their mouths to spare their noses from the stench of demigod poop.

The demigods managed to kick their shoes off during the flight from the forest to the House of Night, the residence of one of the most powerful goddesses alive. Their hands were covered in slobber from jamming their digits into the mouths in the effort of figuring out which finger/fingers were the best to suck on. They both determined that the pointer and middle fingers of their right hands was best.

Soon enough, the arai were flying through a huge open window of a massive black mansion that radiated a sense of foreboding and unwelcome. However, the room the vengeful spirits flew into was a total contradiction to the exterior. Simply put, the arai went flying into a colorful nursery with furniture big enough to accommodate a couple of teenagers. A crib big enough for two, a couple of exersaucers, a huge playpen, two big changing tables, a toybox, a couple of highchairs, and everything else you could think of that might be in a nursery.

Standing out amongst all the colorful baby paraphernalia was an ancient being, born at the onset of the creation of the cosmos and all that was in it. A tall woman, wearing a dress that looked to be cut from the depths of space itself, shining with stars and galaxies, with solid, glowing white eyes, skin that was dark but not in the way that black and brown could be used to describe it, black hair that waved around on its own, and two huge wings that were made of nothing but shadows rested folded up against her back.

Nyx, the primordial goddess of night.

And she looked as excited as a small child on the morning of Christmas, bursting with energy at seeing everything Santa Claus had brought.

In this situation, her children the arai were Santa and Percy and Annabeth were the presents.

We brought them, Mother. We gave them the curses you wanted us to give them. Among others. Iapetus was not a problem.

"Oh, they're just precious!" Nyx gushed like a mother seeing her own newborns. "You all did so well, my darlings."

The arai practically vibrated with pride at their mother's praise.

"Now, leave us. There is much to be done with your newest baby siblings."

The demons left their mother alone with the baby-minded demigods.

Despite her terror-inducing appearance, so scary that most monsters fled at the mere sight of her, and most of her nephews and nieces, the Giants and Titans, refused to speak her name, Percy and Annabeth looked up at Nyx with pure wonder and amazement in their innocent eyes.

"Hello, babies," Nyx said warmly, "I'm your new Mommy."

"Ma-ma," Percy said. He sat on his messy butt, reaching out to her while making grabby hands.

Nyx leaned over and picked the stinky boy off the ground. "That's right, Percy. I'm your Mama. And I see you had a big accident in your pants, didn't you? That's okay. Babies like you aren't ready for big kid underwear. That's why they need diapers."

Nyx walked over to the changing table. She set Percy down on it and started removing his clothes. His tattered shirt, his falling-apart shoes, his wet and torn pants, and finally, his filthy, poop-filled underwear. Nyx frowned a little at what she saw. Not the goopy messy that covered her son's butt, but at all the muscles on his body. Percy was certainly above average for a male his age, taller, with broad shoulders, and his muscles were all cut and lean, with abs sharp enough to grind cheese. Nyx didn't like it.

She tapped Percy's forehead, making him gurgle and reach for her finger. The touch sent rivulets of darkness through his veins, and his body started changing. His height remained the same, but his messy hair got longer and straightened out. His shoulder's thinned and his hips widened. His muscles lost mass, getting smaller, but no less firm. After a few seconds, Percy had gone from buff swimmer, to ballerina. A much more feminine build.

But his package remained the same size and shape, totally untouched by Nyx's power at her disretion.

"Much better," said Mother Night. "I prefer daughters to sons for the most part, but I'm willing to let you keep this just because."

Then she set about manually wiping Percy clean. She could've just snapped her fingers and made him clean, but she didn't want to do that. Physical contact really solidified it in his infantile mind that she was Mommy and that she loved him. Wipe after wipe met Percy's skin, and after so many wipes, he was clean as he could be.

"There we go. Now you're ready for your diaper!"

Out of the drawer of the changing table, Nyx pulled out a thick, teen-sized diaper with a design of Disney's Ariel on it. She unfolded the diaper and lifted Percy's legs, sliding her diaper under her smooth, hairless butt. She let the legs down, sprinkled powder on the feminine boy's crotch, then taped the diaper nice and snug. Nyx reached into another drawer and pulled out a dress that had Ariel playing with Flounder on the front of it. The skirt of the dress was very short, allowing for extremely easy checks and changes of Percy's diaper. For the final touches, Nyx tied Percy's hair into pigtails using ties that had little seashells attached, and then she set her new daughter down on the ground with a kiss on the head.

"And now for the other little stinker," Nyx announced as she went over and picked Annabeth off the ground to set her upon the changing table for her own turn.

Repeating the process, Nyx took the girl's clothes off, her shirt and bra, her socks and shoes, and finally her shorts and panties. Just like her boyfriend, Annabeth's butt was totally covered in her poop after having sat in it so many times. Nyx set about wiping her clean, grabbing her legs by the ankles to hold them up for ease of access to her messy nethers. Once Annabeth was clean, it came time for her diapering.

"And don't I have just the diaper for you, daughter of wisdom," Nyx smirked.

She reached into the drawer of the changing table and brought a diaper depicting Elsa and Anna from Frozen. She taped it around Annabeth's hips, and then produced the girl's own dress, also with Elsa and Anna upon it. Nyx tied Annabeth's blonde curls into pigtails, and set her down on the ground next to her sister with a kiss on the head.

"There we go, babies. All dry. You two look so cute in your diapers and dresses!"

More than that, they looked so pathetic it was delicious. The strong and powerful son of Poseidon, reduced to a girly boy in a Little Mermaid dress and diaper that crinkled as he crawled about on his hands and knees like an infant. The proud and uber-intelligent daughter of Athena, also wearing a diaper and a short dress that made it easy to see when she wet and messed herself, also crawling like a little baby.

Nyx loved it. Such great heroes, now her children to smother and coddle and humiliate without them even being aware of it.

"Alright, babies. Time for lunch!"

Nyx scooped them up, placing them on her hips, and she settled in the rocking chair. The top of her dress vanished and she pushed the heroes' heads to her pert nipples. Percy latched on and instantly started suckling, but Annabeth required a little more coaxing. She got it though, and just like her was sister, was soon greedily suckling away at the goddess Nyx's breastmilk, laced with all kinds of magic.

None of least was a combination of laxatives and diuretics.

Nyx smiled serenely as she watched the babies suckle from her. She stroked their heads, many fantasies of the future running through her head.

A future filled with many full diapers.

PJOABDL

Something was wrong. Annabeth didn't know how she could tell, but she could. Something just felt off. Of course, she couldn't possibly discern what given her curse-addled mind, but she could still feel something out of place.

The reason she even had an inkling of wrongness stemmed from the fact that she hadn't taken the full brunt of the arai's curses. Percy had been the one taking them, and while she'd been a target with each curse, the majority of the brunt of it was aimed and received by the son of Poseidon. Therefore, Annabeth retained a small, teeny weeny fraction of her intelligence as a demigoddess.

But only enough to recognize that things were perhaps not as they should have been, but only in the same way that she understood what the word "no" meant. If only barely.

Whenever Mommy set her and her sister up in the highchair and put mush in their mouths via spoon, Annabeth felt that same "no" feeling. And she felt the same thing when Mommy set her and Percy on her lap and let them suck on her nipples. There was also the clothes she and Percy wore: the bright colors and the repeating shapes that were characters-it felt like "no" to Annabeth. She also felt "no" when it came to her diapers, but what else was there for her to wear?

Speaking of diapers, Annabeth felt an especially big NO whenever she felt her tinkle flowing out of her into her diaper, making it warm and swell between her legs, and a super duper NO whenever she felt her diaper sag and expand whenever she pushed a big, stinky load of poop into the padding.

And she felt the same way whenever she saw Percy going tee-tee and poo-poo in her diaper.

But Annabeth didn't understand why she would feel "no" about these things. And she couldn't talk like Mommy could talk, so she didn't bother asking.

Honestly, Annabeth wasn't really bothered by her "no" feelings. Mommy loved her. Percy loved her. She loved them both. That was enough to override the no feelings. Besides, they were fleeting and getting more and more spaced out every day with each time she was spoon fed, each time she suckled, each crawling step she took, each diaper she filled and soaked, and each slobbery kiss she shared with Percy.

Until one day, Annabeth stopped having "no" feelings, and couldn't remember ever having them in the first place.

Nyx got bored with watching Annabeth more or less kind of fight the magic, and so she upped it and crushed the girl's mind entirely, rendering her just as infantile as her sissy sister.

PJOABDL

Why had Nyx done this, you might be wondering. Why had she gone out of her way to see to it that Percy Jackson and Annabeth Chase, two of the most powerful demigods of the age-in all of history-were reduced to a couple of stinky baby-like teenagers that would forever remain as crawling, babbling shadows of their former selves? Simple:

She wanted to.

She had no real rhyme or reason to it, she just wanted to see the half-bloods as overgrown babies, and she wanted to be their mommy.

And so she was.

As for the rest of the world, well...

"Sister!" Nyx crowed when Gaea came to visit her in the Mansion of Night one day.

"Sister," Gaea greeted warmly.

The two primordials hugged each other tightly.

"It's so good to see after so many thousands of years," Nyx said. "How go things up there on the rest of you?"

Gaea smiled at the little running gag. "Much better now that the pesky Olympians are out of the way and the humans have been returned to their proper places. Now they no longer pollute my skies or my rivers or my lands. Nor are they out there slaughtering each other in droves. Filthy mongrels."

Nyx nodded sagely. "Filthy indeed. Speaking of filthy, who are all these little stinkers that you brought with you today?"

Gaea beamed just like the proud mommy that she was. She brought along a modified stroller, one that was a single row with eight seats to it. From left to right was Thalia, Reyna, Nico, Hazel, Frank, Leo, Piper, and Jason. All the former heroes were just like Percy and Annabeth: diapered teenagers with the minds of babies. The girls were all wearing short dresses with Disney princesses on it, with exposed diapers that matched whichever princess was on their dress. However, the boys hadn't been turned into sissies like Percy, and were still very much in possession of their male physiques, but they were clad in just t-shirts and diapers, with their clothing depicting a Disney prince.

"These are the ornery little brats that thought they could stop me. I heard about what you did with Percy and Annabeth, and couldn't resist doing the same to them. Now they're all my precious babies."

"Yes, precious little ones indeed," Nyx nodded.

She turned and let her sister enter the Mansion, the door widening to allow the super wide stroller to enter. Percy and Annabeth were inside, playing with baby toys on the living room floor. When the former heroes all saw each other, there was a massive ruckus as they squealed in delighted excitement. Apparently, they recalled they were friends in their previous lives as heroes.

That, or they were just excited to see other people and didn't have a clue as to who anybody actually was.

Gaea unlatched the stroller trays and undid all the seatbelts. Her babies wasted no time in launching into a crawling stampede towards Percy and Annabeth, who crawled to them just as fast. Percy went for the boys and the boys for him despite how he was all girly and wearing princess stuff, while the girls all went for each other.

Nyx and Gaea occupied the couch and just chatted and talked with each other while the babies played. It wasn't too long however until Nyx looked up and saw Annabeth sniffing Piper's butt, Piper's diaper bulging in the seat. The same was for Reyna and Thalia. Most of the boys had dirty diapers as well, with only Frank having a clean diaper. Right now, anyway.

"I smell some little ones that need their diapers changed," Nyx cooed.

"I'll take half if you take half?" Gaea offered.

"Nonsense. I'll change my babies' diapers, and you will change your babies' diapers."

"What kind of aunt doesn't change the diapers of her nieces and nephews?"

"This one," Nyx said flippantly.

Gaea sighed. It wasn't that she was disgusted by wiping poopy butts, she was just vexed with the amount of time it took. Only to then turn her back, and then the diaper she just changed became wet.

As Nyx attended to the diapers of Percy and Annabeth, Gaea began the process of changing the diapers of her sons and daughters.

Gaea would stay in the Mansion of Night all day until night came and Nyx had to attend to her duty as the goddess of night and left, leaving Gaea as the babysitter to ten diapered demigods.

But she managed.

And for eons to come she and Nyx would manage.

They managed the earth and the night, and they managed thousands upon thousands of stinky diapers.

Hope you liked it!

I also figured out to turn words into hyperlinks, so now you can get a visual for yourself of what I'm talking about. I hope, anyway.

The next thing coming up is Diokno4x's request of Reyna and Thalia having a messing contest in their pants and whatever underwear they have on.
