Chapter 1: Hot as Lava
Tom Lucitor threw his arms up and leaned back, thrilled screams leaping from the young demon prince's throat as he flew through the air. He was pressed back into the chest and stomach of Marco Diaz, his human friend. But right now, he wasn't the Marco he'd first met. No, this Marco was tall, strong, and grizzled!
He'd been aged sixteen years by spending the time in another dimension, one synchronized to a different time than that of Earth and the Underworld. This dimension. And while they spent days, weeks, months, even years here, only seconds and minutes would pass on the other side.
"This is awesome!" Tom shouted as they sailed through the air, Marco's dragon-cycle, Nachos, carrying them on the hot volcanic winds.
"Ready?" Marco asked, muscled arms trapping Tom on either side as he reached forward to rev Nachos' throttle. The dragon roared underneath them as she shot through the air, heading directly for a plume of erupting lava!
"Yes!" Tom leaned forward, putting his face right into the heat. Marco waited till the last second to pull up, eliciting more thrilled screams from his sweet demon companion, before he steered Nachos higher into the red sky as they rode the plume towards an approaching wall of clouds.
They broke through the cloud cover, went into freefall for just a moment before Nachos caught herself. Tom pressed back into Marco, giggling as he held tight onto the human's arms, his chest heaving.
"Look," Marco said, nodding at the sea of scarlet clouds and black soot that lay beneath them. Spots of hot orange appeared and disappeared, spreading far and wide as far as the eye could see. And Tom has three of them, so he would know. "Isn't it beautiful?" Marco rested his chin on Tom's head, being careful of his horns.
"Yeah, reminds me of home." Tom leaned right back into Marco; his pointed tail wrapped firmly around the human's thigh.
"Knew you'd like it," Marco hummed, one hand leaving Nachos' handle to instead rest on Tom's chest. "The Caldera Forest reminds me of you too. Hot, exciting, thrilling, makes my heart beat a thousand times a minute," he continued, the smirk dripping from his words.
"S-stop," Tom blushed, though he couldn't fight the giggles that bubbled out. "I'm not that great."
"Yeah, you're better," Marco whispered into Tom's ear, his hand drifting down over the demon's stomach, just barely playing with the waistband of his shorts. "Way better. The Caldera Forest never once made me wanna dedicate my whole life to them." Then he kissed Tom's neck.
"Whoa," Tom moaned, hips grinding up against Marco's hand, his own hand reaching back to thread through his human's hair. "I, uh, the scissors!" Tom could feel himself stiffen in his shorts. Marco's loving touch usually had this effect on him, but adult Marco, so much bigger than him, he was just so much more man than before. Not that he had any issue with Marco's usual fourteen-year-old self, this version of him was the same, but more.
Wordlessly, Marco pulled his dimensional scissors from the inside of his coat and held them out, tearing a hole in space that Nachos swerved around and flew right through. They were no longer in the Caldera Forest, far from it and now somewhere much more familiar. Marco's house, the one he'd made for himself during his decade and a half in this dimension.
They disembarked Nachos who waddled her own way into her pen, knowing her job was done. They were in the middle of a thick, nigh-endless wood, Marco's house made of pitch-black logs interlocked to make what looked like an old shack. But inside, that was where the magic was. Literally.
Marco dragged Tom inside and lifted the teen demon up into his arms, his legs wrapped around Marco's waist.
"I'm gonna make walking a thing of your past," Marco whispered into Tom's ear before raking his nails down his back and biting his neck.
Tom flushed and felt a pulse in the pit of his stomach, his cock straining in his shorts. "Yes, please," he begged, not used to being able to give in to Marco so easily. He did submit to him every time, and yeah, he was always left a warbling mess by the time Marco finished with him; but that was when Marco was a human teenager, and Tom's demon instincts had to be coaxed into compliance.
Usually, Marco needed to hold him down, talk filthy to him, remind him whose he was and what was going to happen. Only then would Tom let him in. By that point he was putty in Marco's hands, bending any which way he pleased, mewling for him and needing him, but again, it usually took work.
Now, however, Tom's instincts–his whole self–were Marco's. His body didn't need convincing that this man owned him. It knew. Tom knew.
Marco fell onto the couch, Tom under him as he started to tear off the teen's clothes. First his shirt, and Marco's hands traced all over the demon's chest and stomach. He pulled away and Tom mewled. But it was only for a moment. Marco yanked Tom's boots off, pulled at his shorts and then they were gone too, the demon's knees pushed to his chest as the last of his cover was taken away.
Now naked, Tom wrapped his arms and legs around Marco, forcing their lips together. Marco pushed back, his hands kneading and squeezing Tom's bare cheeks as he pushed his tongue into the demon's mouth. They moaned against each other as Marco grinded his hard bulge against Tom's stiff little member.
"Take these off," Tom demanded through heavy breaths, his fingers fiddling with Marco's belt. The human shrugged his jacket off and kicked away his boots.
"Please," Marco insisted, slowly lightening his touch as he smirked down at the prince.
Tom sucked his lips in, flushing deep scarlet, his heart a drum in his chest. The royal, princely part of him balked at the demand, but his body, his beating heart and mind could only yearn. He moaned, pressed himself back onto the couch, his legs spreading, his chin lifting to reveal his neck.
"Please, please take them off, Marco!"
Marco smirked. "As you command, my prince." Marco teased his waistband with his thumbs, tugging on his belt as he looked his demon in the eye. He bit his lip as his hands ran up his stomach and chest, all the way up into his hair. Tom could only groan, his hips bucking, his member bobbing.
Marco chuckled, his hands roaming down again, back to his belt, slowly and deliberately undoing it. His trousers, worn and torn, went slack around his waist. And Tom could only watch.
The prince's eyes followed the lines that delved into Marco's trousers, ogling the bulge that became more and more pronounced with each passing second. His own boyhood looked pitiful in comparison. Then the trousers fell, and all thoughts of inferiority left Tom, just as the drool dribbled down his chin.
Then Marco was on him, his firm, strong, pillar of a body was over him. Unmovable. Unflinching. Indomitable. Tom was Marco's to have.
Tom's breath went slow, Marco's cock laid against his own made his princely prick look like a child's plaything. Even back on Earth, when Marco was his teenage size, he still put Tom to shame. Not that Tom cared that much, especially when Marco put his weapon to good use.
"Is that, is that going to fit?" Tom couldn't look away from Marco's member, and he couldn't tell just how far it would go inside him. He definitely wouldn't be walking after this.
Sex in this dimension was something they'd discussed before. They already had an explorative relationship before, one of trust, love, and passionate fucking. Anytime, anywhere. Home, school, the park, anywhere they thought they could get away with it.
So, when Marco took Tom here, and he was obviously going to be bigger, it was something that warranted discussing. Tom was all for it, Marco only needed slight convincing. But now that it was happening, Tom could only imagine how much he was going to feel this.
"Sure it is, you said so yourself, right?" Marco said, leaning in and brushing his lips against the shell of Tom's ear. "Don't you want me to fuck you? Hard?"
Tom moaned, nails digging into Marco's shoulders as he bucked his hips and grinded their cocks together. He buried his face in the human's neck, his tail wrapping around his thigh as a shudder went through his body.
"Yes! Yes, please!" Tom begged, his little hole quivering hot as he thought about Marco drilling into him.
"If that's what his majesty wants." Marco pulled away – Tom whined – and pushed the demon prince's knees to his chest, giving the human access to everything he'd need. He opened his mouth, leaned in and took Tom's cock into his mouth, all in one go. Tom moaned and squeezed Marco's head between his thighs.
"Marco! Marco!" Tom yelled, bucking his hips up into the human's mouth, his cock dribbling and pulsing as Marco worked his tongue up and down his shaft. "Fuck! Marco!"
Then Marco pulled off, his slobber coating Tom's cock as he pushed the prince's knees back to his chest. "Easy, Tom, don't need you finishing yet." Marco lifted Tom by the hips, just enough for him to lean down and press his mouth between his parted cheeks.
"Oh! Oh, Marco! Marco I love you!" Tom declared, feeling his nether regions quiver in heat.
Marco didn't reply, he just teased Tom's hole with his tongue, taunting it with pressure before pressing it in. Tom's reaction was to reach down and press on Marco's head while pressing into the touch as much as he physically could.
"Marco! Marco! Oh! Marco!" Tom moaned and gasped as he felt the human's tongue slide inside, his breath hot and his three eyes rolling back into his head.
A moment later, Marco rose, smirking at Tom as he wiped his mouth with the back of his hand. His eyes narrowed as he pulled the demon by his hip, one hand firmly on his thigh.
"You ready?" he asked as he pressed his cockhead to Tom's slick hole. Tom just glared at Marco, his breath still heaving as he arched his back and moaned, his nails clawing at Marco's shoulders, trying with all his might to drag him in.
"I'll take that as a yes." Marco pressed in, letting out a moan of his own as Tom's hot, tight, velvety walls compressed wetly around his cockhead. "God!" Marco grit his teeth, his hands squeezing up Tom's legs, grasping onto his ankles and pushing them behind the teen's shoulders as he pushed more and more of his length inside.
"Oh! Oh! Fuck! Fuck! Fuck! Fuck! Marco! Oh fuck! Deeper! Faster!" Tom shouted and writhed, feeling himself be entered deeper than he'd ever been before. Marco wasn't just bigger than before, he was huge!
"Tom! I can't stop! You're so tight! So hot!" Marco rasped, pistoning his length deeper and deeper into Tom's seemingly endless folds.
They'd had hot sex before, really hot, literally, but never like this. Tom and his body screamed for Marco, needed him, and Marco couldn't stop himself. The second he felt his hips press into Tom's cheeks, buried to the hilt, he started to draw out, roaring in fiery ecstasy and Tom sounded his own pleasure off right into Marco's ear.
"Fuck! Fuck! Tom!"
"Marco! Marco! Oh, Marco! Right there! Right there! Oh god yes! Right there! Please! Again! Please!"
Marco didn't need to be told twice. He knew he'd just rammed his cockhead right into Tom's prostate. He knew exactly where it was before, but that was with his teenage boyhood. With his manhood, however, it took some finding again. But he just did, and he was about to let Tom know.
"Brace yourself, my Price of Fire, hell's about to shake." With that, Marco held Tom's ankles so hard they'd bruise, reared his cock out of Tom's ass and slammed back in! He hit his mark. Tom made sure he knew. Nails dragged down Marco's back as he pushed and pulled and rammed and retreated and embedded and retracted.
Sharp, quick claps sounded through the room and the house. The couch shifted, Marco's grunts melded with Tom's gasps. Tom could feel his insides shifting and moulding to try and fit Marco, to take him and have him and make certain he'd never need anyone else.
"Oh fuck! Oh, Marco! Marco, fuck me!"
"I am! I'm fucking you so hard! God, you're tight! So tight! So hot! So…fuck!" Marco's arms wrapped around his littler lover, freeing Tom's legs to squeeze around his human.
Marco's hands raked up Tom's back until his fingers got tangled in his locks. He gripped the bases of the demon's horns and pulled him down in time with his thrusts! Tom let out a shattering moan, his small member spasming and twitching between his and Marco's stomachs, spewing strings of hot cum onto them.
"Shit! Fuck! Tom! Tight!" Marco dragged on Tom's horns, driving his cock up into the demon faster and harder than ever before. As Tom tightened around him, his already weeping cock compelled him to go even faster! Marco did, clapping and riding into Tom as he chased ecstasy.
"TOM!" he yelled, feeling his balls tighten up into his body as his member convulsed and pumped thick cum up into his demon. A raspy moan leapt from Marco's throat as he rode out the ebbing sparks of his orgasm, shooting and dribbling more of himself inside Tom.
"Tom," Marco breathed, his chest heaving and body glistening with a sheen of sweat.
"M-Marco," Tom drawled, his eyes rolled into the back of his head, his limbs limp.
Marco hugged Tom and held him close as he turned them over on the couch, letting Tom lie on his chest.
"There we go," Marco cooed as he rubbed Tom's back. "You okay?"
"Uh-huh," Tom said through deep, ragged breaths. "Can't walk, though," he added, craning his neck to smirk up at Marco.
"Then I did my job," Marco snarked, his hands running down Tom's back until he cupped the demon's velvet-soft cheeks. "Take a breath," he said, giving his lover a moment to brace before he pulled his softened cock from him.
"Fuck," Tom cursed under his breath, the sudden emptiness taking him by surprise.
"Easy, easy, there we go," Marco soothed, pressing a careful kiss to the top of Tom's head, mindful of his horns. When his demon relaxed, he pushed his cheeks together, keeping all but a dribble of him cum inside where he felt it belonged.
With a moan, Tom crawled up Marco's chest. He nuzzled into the crook of his human's neck, his horns a hair's breadth from lethality but kept safe thanks to hours of practice.
"I'm glad we did this," Tom said, sliding his fingers up into Marco's locks. "I love you."
"I love you too, my prince." Marco, with one of Tom's cheeks in each hand, held his demonic prince close, keeping him safe as they fell into a deep sleep, their aching bodies yearning for rest.
