As the night wore on, their little group spread out to mingle and do their own things. Jason and Percy took the opportunity to take a little reprieve for themselves. They'd migrated towards the edge of the festivities, where Jason found somewhere to sit down without leaving the party but with the nearest campers far enough away to give them some breathing room. He kept Percy on his lap; Percy having to sit sideways because of his tail. They happily enjoyed talking amongst themselves and people watching, until Percy began to get bored, as he was prone to do.

"I'm just saying, would anyone really miss us if we ducked out early?"

"I thought you liked the Halloween campfire. You've been talking about it for days," replied Jason, idly rolling the material of Percy's tail between two fingers.

"I do. And we've come, we've partied, we've had a good time," dismissed Percy, breezily. "I was just thinking there are other places to continue having a good time."

Jason huffed in amusement at him. Percy had said that last part far too innocently for it to be anywhere near innocent. He smiled, watching Percy who was preoccupied fiddling with his bracelets and absently curling and uncurling his toes, making his tail flap gently.

"Oh, I dunno," droned Jason, playfully. "I'm quite happy staying a bit longer."

Percy directed a quick frown at him from under his bangs, automatically going into a pout that Jason found adorable.

"But we could be having so much more fun elsewhere," he complained. He wiggled aggressively in Jason's lap, kicked his tail and whined. "And my legs have been practically glued together in this thing for hours now. I'm gonna cramp~!"

"Should've picked a better costume then, you little brat," laughed Jason teasingly. He bumped his nose against Percy's affectionately.

"You're horrible," pouted Percy, sulking adorably as he turned away from his boyfriend's goofy smile.

But he changed tack just as quickly, straightening up to look Jason in the face properly, expression smoothing out into a pleasant smile.

"Oh but you must be so tired after having to carry me around all night," he said sweetly. He clasped his hands over Jason's shoulder, hanging off him, and rested his cheek on the back of his hand to blink up at the blond in innocent concern. "I just thought you'd want a break is all."

Jason held in his bark of laughter at that and instead spared a moment to pretend to think about it before giving Percy a wide smile. "Nope! I'm good."

Percy shot him an unimpressed look before wriggling in closer against him.

"But you've been carrying me so long," pressed Percy, earnestly. "You must be getting worn out."

Jason simply shrugged at him, enjoying himself. "It's no sweat."

"Oh, of course not," assured Percy eagerly. He kneaded Jason's shoulders while he purred smoothly at him, "not for a big, strong guy like you."

"Strong, huh?" Jason gave him a slow smile, shoulders relaxing under Percy's hands. "You flatter me."

"The strongest," Percy agreed, lowering his voice to meet Jason's gentle murmur. "But just because you haven't broken a sweat yet doesn't mean you haven't earned a little break. We could head back to my cabin and you could let me do some of the work for a bit."

Jason hummed lightly and dipped his head towards Percy, nosing at his hair beside his ear and pulled Percy against him securely.

"You know," began Jason, his voice dropping into the pleasant rumbling octave just above a whisper that always made Percy's spine tingle. He flashed Percy a dark-eyed stare and continued; "it's starting to sound like you don't think I can handle you, Jackson."

Percy felt a rush thrill through him. He'd always enjoyed how easy it was to fluster Jason in front of people: just a few compliments and he started looking like a tomato in no time. But he loved when there was nobody else in earshot and it was just the two of them together like this because Jason lost any hesitations about taking control. People didn't seem to realise it, but Jason could get under Percy's skin just as easily as Percy could his. And there was nothing he liked better than watching Jason sink into his role in response to Percy's teasing.

"Oh, believe me, I know exactly how well you can handle me," breathed Percy, with a smirk. "I know just how easily you can toss me around like it's nothing when you feel like it."

Jason made a low rumbling sound of approval deep in his throat, staring at Percy entranced. Percy watched his eyes darken further as they slowly dropped from Percy's eyes to his lips. Percy felt his mouth tug into a self-satisfied little smirk at the attention. He knew Jason expected Percy to kiss him. Percy bit his lip and flashed an impish grin at him instead. He wrapped his arms around Jason's neck and pressed his chest flush against the blond. He took his time nosing at Jason's neck, pleased with himself to feel Jason tense in anticipation under him.

Percy hummed happily as he brought his lips to Jason's ear, waiting only a beat before biting at his lobe. Jason liked biting. Mostly when he got to be the one doing the biting – not that Percy ever complained about that – but more than welcomed the occasional nibble in return. This time was no different and Jason let out a small groan of appreciation and squeezed firmly where he held Percy at the hip and thigh.

"You're an awful tease, you know that don't you?" breathed Jason, warm breath puffing over the back of Percy's neck and shoulder.

"I could do more than tease if you'd taken me back to my cabin like I'd suggested," replied Percy, lips brushing against the shell of Jason's ear.

"But I know how much you like to earn my attention," teased Jason, with a low chuckle.

"That I do," agreed Percy softly, as he turned his face back to Jason's to let the blond kiss him firmly.

Percy tightened his arms around Jason's neck and kissed back eagerly, feeling warm all over when Jason opened his mouth and deepened it smoothly. Jason ran a hand up and down Percy's side, the skin-on-skin contact making Percy shiver pleasantly.

Percy dragged one hand from Jason's neck down his chest and stomach and back again, fisting in the soft fabric of his low shirt collar. He slid his other hand up to grip at the back of Jason's hair so his boyfriend wouldn't get any crazy ideas about ever stopping kissing him.

Percy found it difficult to keep track of time with Jason's tongue down his throat and hands groping restlessly all over him, so he was unsure exactly how long it had taken him to get so tightly wound under his boyfriend's expert efforts. All he knew was that he was suddenly twice as desperate for some privacy with the blond. Percy was panting against Jason as he squirmed in his hold and was fairly certain Nico would've had another lecture for them both, had he seen the state they were in. Having the advantage of being on Jason's lap, Percy could tell the blond was as ready for action as he was. Jason's kissing had become rougher, more eager, as he tried to bite off his ragged groans. His death grip on Percy would no doubt leave finger-shaped bruises behind. Percy was confident that if they didn't ease up soon his boyfriend was going to start growling right there by the campfire for everyone to hear.

Reluctantly, Percy pulled away, one hand firm on Jason's chest to stop him simply following. Jason's eyes fluttered open, blinking at him rapidly as he summoned some of his usual restraint. His tongue swiped automatically along his bottom lip and he gave a short grunt of displeasure at Percy taking his tongue out his mouth.

"Can we go back to a cabin now?" asked Percy pedantically. "Please?"

When Jason jumped to his feet, scooping Percy up into his arms and then throwing him over his shoulder like it was nothing, he actually did growl. Percy felt excitement bubbling up in his chest and, before he could even consider stopping it, it tumbled out of his mouth in the form of a half delirious giggle. There was nothing he could do (what with his tail effectively binding his legs together and one of Jason's arms pinning his hips to his shoulder) but hang there as Jason executed a swift and purposeful march through the still partying demigods in a beeline to the cabins.

They got a few looks, some confused and some amused, as they went. A few people tried to wave goodbye or say something, but Jason seemed to have a heavy case of tunnel vision and didn't appear to notice them calling out to him at all. He kept his eyes intently fixed on the cluster of cabins and his grip firm on Percy. That left Percy to save their reputation. He pried his eyes away from Jason's ass – which looked fantastic in the tight pants of his costume – and waved goodbye at everyone as they passed, shooting bright smiles and calling lots of see you later's and this was fun, let's do it again soon's. A few campers clearly knew what was up as their hasty exit was also met with catcalling and whistling – even a hearty "Get it, Jackson!" from Travis Stoll. Percy graciously bowed at him: as much he could in his current situation anyway.

Just as they were leaving the area around the campfire, Percy caught sight of Frank, Leo and Nico who had apparently gravitated back together at some point. He caught their eye as they all stared at Jason and he as they marched past with mixed reactions.

Leo, predictably, stuck two fingers in his mouth and gave a loud approving whistle before whooping, "Attaboy, Jason!" Jason didn't seem to hear him, but Leo didn't seem to mind.

Nico rolled his eyes, shaking his head and muttering something that looked suspiciously like 'animals', before raising his voice to shout, "Make good choices!"

Frank just looked at Percy; his mouth slightly open and eyebrows raised, a mixture of confusion and concern. Percy imagined Frank was wondering if he ought to step in and make Jason put him down. He loved Frank, but sometimes it was like he didn't even know Percy at all.

Percy flashed him a winning smile to show his delight at his situation and gave him an enthusiastic thumbs up, letting him know he could stand down: 'It's all good man. I'm about to get wrecked!'

Jason marched straight to Cabin Three, practically kicking down the door on his way in. He threw Percy off his shoulder and onto his bed roughly with a snarl that made Percy's toes curl in anticipation. Percy landed on his back hard enough to bounce a little, a small "oomph!" knocked out of him. He propped himself up on his elbows to find Jason standing at the foot of the bed, just staring at him hungrily. He grinned at him, letting Jason look all he wanted, biting his lip eagerly as he watched dark blue eyes sharpen with intent as they raked down his body. When Jason met Percy's eyes again, he gave him a devilishly attractive smirk and climbed onto the bed, his knees bracketing Percy's tail. He walked slowly on his knees up the bed, before leaning forward on his hands over Percy, leaving just inches between their faces.

Percy stared up at him with bated breath and licked his lips subconsciously. He tried to swallow some of his rising tension and glanced down at his tail, just for a reprieve from the outrageously handsome face of his boyfriend.

"So, what now?" he asked, in a quiet murmur. He flicked the end of his tail. "Fish roleplay?"

Just like that, Jason's sultry expression split into a dorky grin and he barked a laugh. Percy loved the way he laughed. He batted his eyelids at him prettily before breaking into laughter as well.

"Oh, don't do that," cringed Jason, though he hadn't completely gotten over his dorky smile. "Don't try to make fish sexy."

"You don't think fish are sexy?" asked Percy, rolling his eyes to the ceiling. "Why even date me, honestly?"

"I'm just afraid you'll awaken something in me," hummed Jason, brushing his lips along Percy's cheek. He paused to whisper into his ear, "wouldn't be the first time."

Percy grinned and turned to meet him.

"And aren't you glad I did?" he murmured against Jason's lips, before kissing him slowly.

He sighed contentedly against Jason when the blond broke their kiss. Jason didn't go far, tipping his head, resting it against Percy's. His eyes slipped shut as he smiled warmly, breath puffing gently against Percy's face soothingly.

"Thrilled."

Percy felt joy expand in his chest as his face broke into a brilliant smile. He had such a sap for a boyfriend, but he would never ever get enough of it. He kept beaming even as he fisted the front of Jason's shirt and pulled him in for another kiss.

Jason barely had to press forward at all before Percy took the hint and sank back onto the mattress, making sure to bring the blond down with him. Jason supported himself on one forearm to avoid crushing Percy and slid the other under Percy's head and into his hair. He angled Percy's head just how he wanted it for the best access to kiss him senseless.

It wasn't long until Jason had Percy breathless and panting below him. Percy moaned against him impatiently, his hands caught in the billowing folds of his loose shirt. Jason grinned at him, amused, consequently breaking their kiss. Percy rolled his tongue slowly over his bottom lip, looking a little dazed as he caught his breath. Jason gave him a minute to regroup, pressing kisses along his jaw instead.

"Let me – let me just," breathed Percy heavily, hands working between them.

He took hold of Jason's shirt either side of the low neckline and just tore it open, almost all the way to where it was tucked into his red sash: like it was nothing. Jason had glanced down between them to see what Percy was doing, so he had gotten to watch him rip his shirt apart easily. He was aware in the back of his mind that it was a fairly low-quality costume shirt, but the front of his mind was too busy thinking that it was super-hot to be anything less than impressed and turned on.

"I hope you know how to sew," said Jason, just to be an ass.

"Was in my way," shrugged Percy, staring openly at his boyfriend's newly exposed chest. "I'll buy you a new one."

Jason grinned and dipped his head to mouth at Percy's neck, sucking hard below his ear. Percy made a satisfied sound and eagerly occupied himself groping at Jason's chest, sliding his hands along his chest, down his stomach and back up along his sides. Jason licked a thick stripe along his throat, hand clenched in Percy's hair in approval at his touches.

When Percy felt teeth drag along his neck he moaned loudly and arched his hips off the bed (trickier to do in a tight-fitting mermaid tail), wiggling eagerly, desperate for some below the belt contact. Unfortunately, Jason was keeping his own hips out of reach, which Percy found extremely unfair. He made his displeasure known through whining and continued efforts to lift his hips high enough. Jason chuckled and pressed a quick kiss to his lips.

"I know, I know," he muttered softly, sitting back on his heels over Percy's thighs. "I got you, sweetheart."

He ran a hand down Percy's chest and stomach, all the way to the obvious bulge of his crotch in the tail. He cupped Percy lightly and then squeezed firmly. Percy gasped and went rigid, eyes screwing closed, before letting out a low moan and positively melting into the mattress. Jason smirked as his hand continued to fondle lazily. He watched Percy bite his lip and shudder visibly. Jason was just as hard as Percy, but too captivated watching Percy fall apart under him to do anything about it just yet.

"You really are a good-looking mermaid," he laughed, softly.

Percy snorted at him and raised an eyebrow pointedly at him. He rolled his hips firmly into Jason's hand.

"Does that feel like a maid to you? Merman, idiot," grouched Percy, but there was no heat to it.

Jason exhaled loudly through his nose in amusement. He shook his head exasperated but charmed as always by his dork of a boyfriend. He smoothed his free hand up Percy's ribs to thumb over a nipple, gratified by Percy's sharp intake of breath. He played around with Percy a little longer, taking him apart piece by piece until Percy was a trembling wreck beneath him.

Jason brought a hand up to the blue waistband of Percy's tail. Percy's wail of protest was abruptly cut off when he immediately slipped the hand in under the material to reclaim Percy's dick. His eyebrows shot up in surprise when he realised Percy wasn't wearing any underwear under his costume. He was surprised nobody had noticed the outline of his boyfriend's dick through the thin material of the tail. He was surprised he hadn't noticed. It was definitely the kind of thing he tended to notice.

Jason cocked an eyebrow at Percy as his hand closed around his shaft, stoking slowly. He leaned over Percy again, hovering above his flushed face.

"This has to be against camp dress code, surely," he chided.

Percy gave him a sly grin. "You love it."

"Since you've already ditched the underwear," mused Jason lowly. "How about we ditch the tail as well?"

"Best idea I've heard all night," beamed Percy, rewarding Jason with another peck on the lips.

Jason sat back, hooking his fingers under Percy's waistband. He eagerly began tugging the tail down while Percy scooted enthusiastically up the bed.

"Transformation sequence!" yelled Percy happily, as he wriggled, earning a snort from Jason.

Jason tossed the costume aside once they'd successfully freed Percy's legs. Jason drank in the sight of Percy fully exposed and laid out so nicely on the bed for him. What a view. Percy's flush went all the way from his cheeks to his chest; naked save for his camp beads and bracelets and Jason thought he'd never looked prettier. And then Percy had to go and spoil it by opening his loud mouth.

"Oh, look at that – legs!" he exclaimed dramatically.

It was ham acting at its worst and Jason wondered for the millionth time how he could have ever wound up falling for such a dork. Yet even as he rolled his eyes, he felt his lips curve into a gentle smile.

"Wonder what I should do with 'em," sighed Percy, looking exaggeratedly pensive. Then he grinned at Jason from under his lashes, head tilted coyly.

"Maybe…spread them?" winked Percy, as he spread his thighs wide in invitation.

"Oh my god," groaned Jason despairingly. He was fairly positive this was not how the movie went.

Percy may be the worst actor ever, but when he crawled up into Jason's lap to straddle him, hooked his arms around his neck and stuck his tongue eagerly down the blond's throat, the critic in Jason promptly died.

"You know," grumbled Jason, after catching his breath, thumbs stroking along Percy's thighs. "If you keep it up with the terrible mermaid commentary, you might just kill my boner."

"I wouldn't worry about that, handsome. You know what they say," teased Percy. "Someday my Prince will cum."

"You're horrible."

"A good snog would shut me up," beamed Percy brightly, rolling his hips against the blond enthusiastically.

"You forget that I've tried that before," said Jason softly. He squeezed Percy's thighs, keeping their crotches flush against each other. "Ineffective."

Despite his words, Jason attacked Percy's mouth wholeheartedly, biting his lip until it was swollen and red. Percy gave back as good as he got, rolling his hips and moaning wantonly when Jason's hands began kneading his ass. Percy dragged his nails down Jason's chest, eliciting a muffled snarl of want from the blond that only fed his own burning need. Jason made to shrug off the remains of his shirt blindly, but Percy pushed his hands away.

"Leave it on?" he asked politely. At Jason's questioning look, he shrugged with a lopsided grin. "Who doesn't wanna fuck a Disney Prince?"

Jason grunted his amusement but indulged him all the same; ducking his head to suck at Percy's collarbone instead. Percy was beginning to lose his mind at the feeling of Jason's covered erection rubbing between his cheeks as he energetically frotted against it. He reached down, groping for the zipper of the costume pants. When he had successfully worked the pants open and slipped a hand inside, he snorted.

"Underwear? Prude."

He felts Jason's quiet answering laugh rumble against his lower neck, as he finally pulled his boyfriend's dick free. Jason's laughter melted into a deep groan when Percy began stroking him eagerly. He loved the way Jason shuddered against him; the way he pressed his face more firmly into his neck and sucked hard. They'd done this enough times already to know the drill. Without releasing his teeth from Percy's neck, Jason tightened his hold around Percy's waist and shuffled up the bed, careful not to dislodge Percy from his lap. Percy kept one hand working Jason's cock while the other fumbled around in his bedside drawer for the lube he kept stashed there.

Jason held out a hand automatically for Percy to squirt some of the liquid into his palm before Percy covered his own hand as well. He slicked up Jason's cock and rubbed his own leaking erection mindlessly against Jason's stomach for some relief. All the while Jason was working him open tenderly with his fingers and driving him mad. He was moaning embarrassingly loudly as he fisted a hand in blond hair, tugging Jason's face away from his throat so he could crash their lips together again. When Jason finally slipped his fingers out of Percy and gave his rear a couple quick pats, signalling they were good to go, Percy didn't waste any time. He raised himself on his knees over Jason's lap and positioned Jason's cock at his entrance.

He bit his lip as he slowly sank down onto the length, not stopping until he had taken it all in and was sitting in Jason's lap once again. He panted and quivered with how good it felt to be so full. He could feel Jason's arms still tight around his waist holding him close, and the way the blond trembled minutely with the effort of keeping still until Percy decided he was ready.

It started subtly: a slight rotation of his hips. Percy whimpered when he felt Jason's cock grinding deeply against his prostate.

"You're so pretty," rumbled Jason lowly, dark eyes staring at him entranced.

Percy mewled helplessly. Jason stroked a thumb gently across one of Percy's cheeks, admiring the red blush he found so tantalising on his boyfriend.

"So gorgeous," he growled, dragging Percy in by the jaw for a heated kiss.

Jason nipped at his lower lip before pressing his tongue inside. Percy's mouth opened willingly for him with a sweet little moan that set Jason's blood on fire. He smoothed his hands down Percy's sides, coming to a rest on his thighs, kneading them encouragingly as they made out. Percy gripped at Jason's shoulders all too eagerly for leverage and pushed himself up a little, keening into Jason's mouth when he sunk back down again.

One thing Jason loved about his boyfriend was Percy's adaptability. It never took him long to get used to things; be it demigod life, surviving dangerous quests with no memories, or riding his boyfriend's dick. Tonight was no exception and soon enough Percy was riding his cock like a pro. Jason couldn't get enough of the way Percy clung to him, the smooth roll of his hips, the absolutely wrecked sounds that spilled from his lips, the feel of his ass cheeks as Jason groped them, helping Percy keep his rhythm.

He watched the way Percy's cock bounced as he moved, slapping against Percy's stomach, the head slick with pre-cum. He watched mesmerized for a moment before bringing a hand between them to jerk Percy off. Percy's pace faltered as he bucked up into his hand with a cry, ass clenching tightly around Jason, who, in turn, grunted out a curse and thrusted up harshly into Percy. Percy, bless him, did his best to pick his pace back up, but he seemed to be fast approaching his limit and struggled to do so.

With every tug of his cock from Jason, Percy clenched harder around the blond, the rise and fall of his hips stuttering spasmodically. Percy quickly leaned into it with wild abandon, fucking himself desperately (and loudly) on Jason's cock, giving up on rhythm altogether.

"Faster – shit, I can't – faster," panted Percy mindlessly, eyes screwed shut.

The urgency and need in the plea, combined with the furious squeeze on his cock is what broke Jason. He surged forward with a snarl: up on his knees, pressing Percy back against the wall above the headboard harshly, fucking into him roughly. Percy gave an eager, broken moan, surrendering control to Jason entirely. He just clung on around Jason's shoulders for all he was worth and enjoyed the ride. Jason's hips pistoned furiously against Percy's ass, driving his cock as deep inside him as he possibly could. The sound of the bed rattling against the cabin wall along with Percy crying out for more spurred him on like a man possessed. His fingers dug in sharply where they gripped at Percy's hips, holding him firmly in place.

He watched Percy's camp necklace bounce hypnotically against his chest with every thrust; the beads making a satisfying clacking sound, almost too faint to even hear under Percy's moans. Jason found himself thrusting harder just to see how high he could make those beads bounce. Percy's head was thrown back, hands fisted tightly in the shoulders of Jason's shirt, his cock visibly twitching against his toned stomach. The sight of him so thoroughly wrecked and just taking it so well made something possessive and primal burn bright in Jason's chest and he carried on, railing his boyfriend mercilessly, feeling that private side of him purr in satisfaction.

And then all of a sudden Percy was tumbling over the edge, practically screaming as he came, cock erupting all over his chest and stomach. He shuddered through it, hands and thighs trembling around Jason while his ass clamped down like a vice around him. Jason was dragged right along after him, grunting gutturally and seizing up as he let loose inside of Percy.

Jason unwound all at once, the tension in his rigid frame melting pleasantly as his high dwindled. He carefully sank back on his heels, pulling Percy down gently into his lap. He held Percy against his chest securely, eager to keep him close. Jason stroked up and down Percy's back, pressing kisses to his cheek adoringly and murmured soft praise against his skin. Percy gave him a slow, satisfied smile that radiated pure joy and Jason felt his chest constrict with the burst of affection he had for this boy. Percy glowed when he smiled like that and it utterly melted Jason every time without fail. Unable to help himself, Jason kissed Percy for all he was worth, smiling against him when Percy automatically kissed back just as reverently.

Percy had sagged against him, always a boneless bag of mush after an energetic night, just another thing Jason found hopelessly endearing. Cuddly Percy was just as good as horny Percy. And Jason had been a sucker for cuddling before he'd even met Percy, so he would never deny him the pleasure. They stretched out together on the narrow camp bed, Percy tucked comfortably into Jason's side under his arm. Jason had expended the last of his energy to tug up the blanket and tuck it around Percy so he wouldn't get cold during the night with no clothes on. He had left it just barely over his own waist, too tired and still pleasantly warm from their activities to bother covering himself. He sighed and closed his eyes, letting his head sink back comfortably into the pillow, fingers absently stroking along Percy's side as exhaustion rapidly crept up on him.

Percy watched Jason relax into the sheets contentedly. He admired the view without shame once Jason eyes had closed. Percy had picked out the prince costume because he knew how well it would suit Jason; all put together and handsome in a respectable way. But he loved this look on his boyfriend just as much. Jason looked thoroughly debauched: hair ruffled, cheeks still faintly tinted pick, loose shirt torn open all the way to the sash at his hips, leaving his sweat slicked chest and abs on display for Percy.

Percy nuzzled his cheek against Jason's chest lovingly, curling into his side even closer to settle in for the night. It was only when his toes brushed against something unexpectedly hard under the covers that he realised that Jason had completely forgotten to take off his boots. He peered up at Jason's relaxed face to see that he had already dozed off.

'What an idiot,' he thought tenderly around a yawn.

Percy laid his head back down on Jason's chest, closing his eyes with a tired smile. He wasn't gonna wake Jason up now, but he certainly planned to tease him about getting so caught up in everything that he had fallen asleep with his boots on like a dork. Perhaps Jason had been more into fish roleplay than he'd wanted to admit.
