The end of the Giant War meant a time of healing was upon everyone. With the Romans at Camp Half-Blood helping to repair the place, making friends, meeting new half-siblings, it only made sense for the Hunters and Amazons to come by as well to help, and also to recruit since Orion had all but destroyed both groups during his assault in Puerto Rico. But mainly to help.
Officially.
Thalia could honestly just say she was there to see her brother, Annabeth, Percy, and Nico, specifically in that order. Of course, the snag to all of that was that Jason had his nose buried in Piper's ass, figuratively and literally, Annabeth was being run ragged left and right helping to design new cabins and help Jason with his big project, Percy practically glued to her ass too, and Nico was having his ass checked out by Will. Thalia was honestly feeling left out; why didn't she have anyone to admire her ass?
Well, she did, but romantic love of any kind was forbidden in the Hunt, no exceptions. Anyone who fell in love, lesbian or otherwise, and kept it secret, was subject to Artemis's wrath for breaking her oath, which usually ended up with someone turned into an animal, and anyone who confessed to Artemis they'd fallen in love would be honorably discharged from the Hunt. The loop hole was that one could have sex and it not be romantic, unless it was with a man, in which the "company of men" clause would be broken, and there was no going back from that.
Though, Thalia often wondered if having sex with a boy would be a loophole, as in, a male that was much older than a child but hadn't become enough to be considered a man.
Probably not, all things considered.
Of course, all this thinking about ass and sex stemmed from the fact that becoming a Hunter of Artemis meant immortality at the age you joined. For Thalia, that was days before she turned sixteen, making her an immortal teenager smack in the middle of puberty for the rest of her life. That meant she got to deal with all the accompanying additives, like horniness, and that horniness got worse the more stressed she was, and there was nothing more stressful than being in another war, watching your sisters get murdered by a guy with attachment issues, and then you're tasked with finding girls to fill the spots.
Granted, this situation wasn't all bad; as it gave Thalia the opportunity to relieve all this stress in her favorite way.
"Hey, Thals, we're going to school Apollo's boy in archery. Wanna come?" one of Thalia's Hunter sisters asked, the rest surrounding her at the door.
"Nah, girls. I think I'll blow off some steam."
The girls all got knowing looks and nodded, heading out of Cabin 8, leaving Thalia all by herself. A few seconds passed before she took a deep breath and released it.
"Yeah..."
Rolling out of her bunk, Thalia grabbed her pack from under her bag and unzipped it. Enchanted in the same way Hermione's way bag was in the Deathly Hollows, in that it was only so big but an entire house's worth of stuff was inside, ready to be called with a thought. Hunter standard issue, of course. However, what Thalia called from her bag was not at all standard issue, and was a total contradiction to her reputation and typical attitude, at least in nature. The design was pretty spot-on.
A thick, white square, covered in black skull-and-crossbones symbols zoomed into Thalia's hand from inside her bag. She set it aside, called up a white bottle with a blue top and a sticker that said "Johnson and Johnson."
A Rearz Rebel diaper and a thing of baby powder.
Thalia didn't waste any time, dropping her jeans and thong, her eyes screwing up a bit at the sweet feeling of the strap being peeled away from her butthole. A look down in the seat of her underwear made her wrinkle her nose at the little smear therein, and she made a mental note to put that much more effort into wiping her butt the next time she pooped. Though, with this particular underwear, it wouldn't be a question of wiping so much as how long she'd spend in the shower afterward.
Thalia took off her combat boots and stepped out of her clothes, leaving her naked from the waist down. She unfolded her diaper and sprinkled the whole inside with powder, filling the cabin with the wonderful sweet smell. Thalia brought her diaper between her legs and brought it up, using her thighs to keep it in place as she did the right bottom tape, then the left bottom tape, then the left top, then the right top, and then she adjusted the tapes accordingly until it fit on her in a way she liked.
Without putting any pants on, Thalia flopped onto her bed with a happy sigh. She rolled around a bit, enjoying the crinkling sound of the plastic, the thickness between her legs, and the soft feeling of the padding against her skin. Yeah, she really did like her diapers.
The door to the cabin opened. "Hey, Thals. Sorry. Forgot something."
"You just wanted to see me in my diaper," the daughter of Zeus said dryly.
"Welllll...that too."
Horny daughter of Venus, Thalia thought with an eye-roll.
The Hunter got her item and left, but not without one last comment over her shoulder, "Let me know when you need a diaper change!"
"Not a chance!" Thalia called after her adopted sister.
Yeah, the Hunters knew about Thalia's diaper love, and none of them cared. When you're centuries and thousands of years of old, seeing the many horrible and disgusting things that mankind did, a girl wearing a diaper was actually something of a welcome sight, compared to, let's say, people being sewn together in such a way that they resembled a centipede.
Ahem, anyway.
So, yeah, the Hunters knew that Thalia liked to wear diapers, and none of them cared, with some even offering to baby her and change her, including Artemis herself. Apparently, it was something she and Zoe used to do, the late lieutenant blowing off steam by diapering up and letting Artemis treat her like a baby. Allegedly, sometimes in reverse, which made Thalia feel really hot between her legs at the thought of the mighty moon goddess in a diaper, being breastfed by Zoe.
Thalia got up and went to the window, pulling aside the curtain to look outside. She frowned when she saw Percy and Annabeth together. She went over and pulled her jeans back up, fighting a bit with her pants to get them up and over her thick diaper. With a bit more of a struggle, she got the zipper and button done, but it was quite obvious based on the bulge around her butt and crotch that she was not wearing panties...but that was nothing a snap of the fingers couldn't fix.
A layer of Mist wrapped itself around Thalia, hiding her diaper bulge and the generous amount of diaper sticking out of her jeans, hidden only by her silver tank top, and masked the smell of baby powder. A quick look in a mirror, turning around and looking at her butt, revealed no visible diaper or bulge. To anyone who looked, Thalia was just the lieutenant of the Hunt, probably wearing a thong under her jeans.
The daughter of Zeus left Cabin 8 and caught up with her old friends.
"Thalia!" they greeted, bubbling with happiness at seeing her, making Thalia's heart soar. It always felt good when you had people in your life who got so happy to see you.
"Annabeth, Percy!" Thalia exclaimed, hugging them both, hugging Percy a bit tighter, just a bit longer.
"Are you two busy, or did you finally get a free moment?"
"No, we're actually free right now," Percy said, looking Thalia in her electric blue eyes. "Did you have something in mind that we could do?"
"Yeah. I had something in mind."
Annabeth's grey eyes flicked between them, then darted at Thalia's crotch. She focused a little bit and saw through the Mist, seeing the diaper making Thalia's jeans bulge, sticking out of the waist, showing through the gap between Thalia's tank top and pants. Ah, so that's what this was about.
"What?" Annabeth suddenly called. "You need me over where? Coming!"
She just sprinted off, giving the two their time. It was an odd relationship between the three of them, one that Annabeth didn't bother trying to figure out. When it came to Thalia and Percy and a diaper, she just ducked her head and got away. She understood where Thalia's diaper thing came from: having to take care of baby Jason and juggle and alcoholic mom, seeing how easy Jason lived in his diapers relying totally on Thalia, and then having Jason suddenly ripped out of her life, left some scars on the girl's psyche, one's she tried to smooth over.
Annabeth could clearly remember when she, Thalia and Luke were on the run together. Living on the streets sounded fun until you needed to poop and you didn't have any toilet paper or a restroom, and you couldn't go into a store because of how much you smelled of sweat and trash, and how much grime was caked on your clothes, and the police would be called if anyone saw you. Coming by clothes was hard, since even Goodwill was grounds for some worker to call the social services, so clothing and food had to come by way of smash-and-grab operations, and underwear was certainly included in those ops. Only, sometimes, that underwear was for bedwetting girl.
Yeah, in addition to snatching Cat and Jack hipsters from the shelves of Target, Thalia also grabbed some Goodnites from time to time, the feel of the of the nighttime pants bringing about the good memories of her time with Jason.
Annabeth had dabbled a bit in wearing diapers, calling up memories of her childhood being neglected for her little brothers, but she had to be in a really specific mood to wear a diaper, and she was very rarely in that mood, especially today when she'd patched things up with her mortal family.
Luke never wore a diaper to Annabeth's knowledge, not from the time they first met to when he destroyed Kronos.
As for how Percy knew that Thalia wore diapers, well...
The vehicle-hauling train generously provided by Apollo sped West towards California, the four questers each occupying their own car, doing their own thing. A thought struck Percy and so he left his car, maneuvering down the aisle to where Thalia was at. A typical hot-headed 14-year-old, Percy didn't even think to knock, just reached and opened the door to the backseat.
"Hey, Thalia, I...aye-yuh-yuh-yuh-aye..."
Thalia stared at him, wide-eyed and with a dropped jaw, her jeans pushed down to bunch around her ankles, one hand under her shirt, groping herself, her other hand down in her diaper, a simple white thing with blue tapes and a yellow wetness strip in the middle.
Brain function returned and Thalia yanked Percy into the car using a gust of wind, slamming the door shut behind him, and she pinned him down. "If you tell anyone about this, I'll make sure you need diapers for the rest of your life, got it!?" she hissed.
Percy fervently shook his head, trying to ignore Thalia's slick and glistening hand just inches from his face.
"And just as a warning..."
Thalia pressed her finger against Percy's pubic area, above his dick and below his belly button, and made him jump when she sent a shock right into the muscles.
"Ow! What did you...just...do..."
Thalia got off him just as the plumbing started working. Percy stared at his crotch in shock as his bladder released, hot pee soaking his underwear and jeans, rapidly streaming through his clothes, going down to soak his socks and shoes, and pooling around his butt as gravity and the angle of the seat caused a puddle to form where he sat.
Thalia smirked. "Uh-oh, did widdle Pewcy go tee-tee in his undies? Huh? Did the big boy have an accident?"
Percy glared at her. "What did you just do!?"
"Sent an electric shock to your bladder muscle to forcefully leave it relaxed. It was just a little shock, so your bladder should contract again by this time tomorrow. Until then, it's going to be open, and so all your pee is just going to flow right through you." She crossed her arms at his glare, and said pointedly. "You're the one who walked in on me, violating my privacy and my space, not even knocking. Just like a little kid wanting Mommy's attention, not a care in the world for her or what she's doing, just barging in on her to demand something."
Percy could only glower, angry at this situation but finding no counterargument because it was entirely his fault and Thalia was well in her rights to punish him for what he did, especially given what she was doing.
"Well...what now?" Percy huffed. "My underwear's wet, my pants are wet, so are my socks and shoes, this seat is soaked, and my bag got destroyed by the Nemean Lion."
"Mine didn't!" Thalia chirped. She reached in her bag, pulling out another diaper, a pair of skinny jeans, some socks, and even a pair of boots.
Percy blanched. "Uh-uh. No way."
"Yes way. I forced your bladder open, so unless you want everyone to know how much of a little pee-pee pants you are, you're going to be wearing a diaper, and will ask me to change you like a baby, got it? I mean, I can always go get Zoe. I'm sure she'd love to hear about a boy walking in on a girl enjoying her private time."
Percy paled and shuddered, needing no further encouragement to submit to Thalia's terms, thoughts of the Hunter's vengeance spurning his compliance.
The two moved to a different car since that one reeked of urine and was ruined. In the backseat of another, just like an actual mother with her baby, Thalia changed Percy out of his wet clothes, demanding that he suck his thumb as she diapered and dressed him, speaking to him in baby talk the whole time as she thoroughly enjoyed exacting her punishment. A few minutes later, and there was Percy, pouting in his diaper and girly, gothic skinny jeans, socks and combat boots.
"Awe, aren't you just the cutest thing ever?" Thalia gushed.
"It feels weird!" Percy whined. "Why do you even have diapers, anyway?"
The mood changed at that point, and Thalia told Percy to scoot over so she could sit next to him. They had their strongest bonding moment ever as Thalia confessed her history, taking care of Jason, dealing with their mom, running away, meeting Luke, then Annabeth, wearing diapers, and how when she wore them when she got really stressed out, like during this quest, Annabeth kidnapped, Luke a traitor, the Titans rising, etc. Percy listened raptly, promised they'd rescue Annabeth and turn Luke around.
So it came to pass that for the rest of the Titan's Curse, Percy was technically crossdressing, wetting his diapers, Thalia changing him, and even giving him a handjob because teenage hormones, and Percy returned the favor by rubbing the front of her diaper until she creamed her padding. Grover and Bianca were totally none the wiser, but Zoe knew, her sharper nose and centuries of experience cluing her in on what was going on.
She just rolled her eyes and muttered something about delinquent teenagers, and told them to stay focused and remember their mission, which they did, obviously, but the whole experience was life-changing for the children of the Big Three. Chemistry was created that they couldn't ignore, and so it was a hard talk with Annabeth about these new feelings, and an even harder choice for Thalia to join the Hunt and escape the Great Prophecy, and her potential failure, but agreements were made.
Percy and Annabeth loved each other very much and had an understanding, and Percy and Thalia loved each other, a love forbidden and dangerous, one they only got to show each other on the very occasions they had time together, like at the end of the Titan War, and like right now, here at the end of the Giant War.
"What is it you had in mind?" Percy asked.
"Well, I was thinking about how boys are very messy things, getting food all over themselves, never cleaning up their rooms, and I think I need to have a look in your cabin to make sure you're being a good boy. After all, how can I expect you to be able to care for my little sister if you can't even properly maintain yourself."
"Well, since I know my words won't convince you, I'll just let my actions speak for me."
"Damn right, you will."
Thalia marched for Cabin 3, Percy behind her, and she opened the door, entering, Percy shutting it behind him.
"Not bad, not bad," Thalia mused at the admittedly tidy state of things, "but what about you, hm?"
"You'll just have to see for yourself," Percy grinned.
Thalia smirked. Back on the train, she'd been taller than him by a few inches, their physiques largely the same. Not so anymore. Percy was now almost a whole head taller than she was, and a great deal more muscular as puberty and exercise had shaped their bodies into what they were now.
Thalia stepped up to him, lifted the front of his shirt and tugged out the front of his shorts. She let out a mock gasp. "No diaper!? We can't have that! A little boy like you could tinkle in his undies and get nasty pee-pee all over the floor! Lay down on that bed, now, before you make a mess everywhere."
Heart beating in excitement, dick getting harder, Percy did as instructed, flopping onto his bed. Knowing where his diapers were at from the last time they did this, Thalia went and pulled one out of the package. Just like she wore Rearz, so did Percy, only his diapers were the original Lil' Squirts, with the blue backing and the pictures of a seahorse, an octopus, a frog, and little bubbles. She went back over the Percy, her diaper feeling a bit damp between her legs.
She took off his shoes, then tugged his shorts off, then his solid blue boxer briefs, freeing his rock-hard member. Thalia eyed it; it was sites like that that honestly made her regret being a Huntress, because where she might've been able to get her hands on toys of comparable size, those were no substitute for the real thing. Percy grinned at her, both of them thinking the same thing.
There wasn't a diaper anywhere in the world that was going to fit over a dick that big and hard.
So Thalia got to work, first licking and swirling her tongue around the head while working the shaft, before taking the whole thing down her throat, working her head up and down while she played with the taught balls. Percy moaned and groaned, bucking his hips into Thalia's face, making her spank him because he kept smacking her nose with his navel.
Despite having lived with a group of lesbians for the past two years, Thalia had some really good dick-sucking skills. That, or Annabeth really sucked at sucking off her boyfriend, or Percy was just a lightweight, because not even five whole minutes into this episode of fellatio, Percy blew his load down Thalia's throat, the lieutenant of Artemis swallowing every drop with expert skill.
"Yummy," Thalia grinned as Percy's slick and glistening dick deflated until soft, Percy himself gasping from the intensity of his orgasm. "Lift your butt, little boy."
Thalia unfolded the huge diaper and placed it under Percy, instructing him to lower, then spread his legs. She folded the diaper up over his flaccid, slimy penis, then taped it nice and snug.
"Yeah! There we go, all nice and protected. Now we don't have to worry about any accidents."
Smirking, Thalia sent a shock to Percy's bladder, forcing it open for the next full day. Open as it was, unable to clench in back shut, Percy could do nothing as his diaper swelled and warmed with a large volume of pee.
Percy smirked back at Thalia. "I learned a new trick," he sing-songed.
Thalia's stomach got heavy at that gleaming eye. "...what trick?"
Percy's smirk got a little bit wider, and he quickly nodded his head forward. Thalia gasped as her anal sphincter suddenly relaxed of its own volition, and her morning load of poop went sliding into her diaper, meeting the resistance of her jeans and body, squishing to fill out the crevice of her ass. Her bladder went next, the muscles relaxing without her command, and she soaked her diaper.
"Whew!" Percy fanned his nose with a grin. "What a stinky girl we have today!"
"What did you do!?" Thalia exclaimed, not bothered by her dirty diaper as much as the fact as to how it became so dirty.
"There's a whole lot of water in your body, especially your muscles," Percy said matter-of-factly.
"Oh~," Thalia drew out as realization dawned on her, and then another thought. "That's actually kind of morbid..."
Percy shrugged. "Nico can turn people into ghosts and control the dead, and you can zap people's muscles. You can probably suck out their wind too, like in Korra."
Thalia had never really thought of using her powers like that, but the more she thought about it, the more she realized just how deadly and dangerous the children of the Big Three really were.
The conch horn sounded, signaling it was time for lunch, making Thalia pale because her diaper was all messy. Percy laughed at her expense.
"No time to change," he said. "Guess we'll just have to be extra careful."
"You're not the one with a poopy diaper!"
Percy cocked a brow. "I never thought I'd ever hear you say the word poopy."
Thalia's cheeks reddened. "Yeah, well, whatever."
Percy winked and turned around. He pushed his diaper up into his butt, and let out a little gasp. Thalia watched, totally transfixed, as the crease was pushed out and then rounded off in the seat. She had to look away and wipe the trail of blood that suddenly leaked from her nose.
"Hah," Percy sighed in contentment, then he looked at Thalia with a grin, "now we both have poopy diapers."
He stepped into his shorts, leaving his big boy undies off, then put his shoes back on. The messy bulge wasn't really all that noticeable unless you knew what you were looking for. He went up to Thalia, and the two stared deep into each other's eyes, sea green and electric blue.
Percy leaned down and kissed Thalia, and she kissed him back, deeply.
"I love you, Thalia."
"I love you too, Percy."

This story came at the request of tottallyafamousperson, revolving around the idea of Thalia wearing diapers as a form of stress relief, Percy finding out about it, and them having a moment together as secret boyfriend and girlfriend after the Giant War.
