The silver walls of the inner labs contrasted with the leafy exterior that surrounded the area. There was a coldness reflected in the clean, clinical steel that even the brightest of flowers could not smother. Luffy had been separated from his crew during a rush attack from the Navy and their new weapons, the Seraphim. At first, the sounds of distant fighting had rung loudly, but the deeper he traveled, the more deafening the silence became. He felt as though he was being devoured by the innards of Egghead Island.
As Luffy made his way through the lab, he felt as though someone was watching him. A gaze; familiar yet not. Only his footsteps echoed in the halls, but he could almost feel… a distant warmth. Like a rush of desert sirocco. He spun around, frowning at the lack of activity.
"Somethin's watchin' me..." he muttered, eyes narrowed, “I swear if it’s Lucci–'' As he turned back, he froze at the sight of a familiar silhouette.
A distant memory, but a cherished one. One that replayed again and again late at night when his crew was asleep and he found himself missing the past. A boy with freckled cheeks, a deadly pipe, and an unfriendly glare. One that would soften at the sight of him.
"Ace....!" Luffy gasped, reaching for the figure– yet it wasn’t Ace. It did look like him as a young teen, but the hair was white; a stark contrast to Ace’s black waves; skin a darker shade than Ace’s had been, yet the freckles were splashed across.
Luffy frowned at the sight of black feathered wings and the flicker of flame that leaped from the figure’s back. Another one of those Seraphim...? He thought the clones were just the Warlords. The Navy hated Ace, why would they–
He froze as the clone approached, its expression blank but eyes glimmering with a sense of... curiosity. Perhaps, familiarity.
Luffy backed up. He knew this was an enemy, that he should fight, but he couldn't bring himself to hurt the clone. Not when it had Ace's face. A face he yearned for every day since that horrible incident at Marineford. Ace's death had affected him terribly, driving him to grow stronger, to fight to protect those he loved.
And now here was a person who looked exactly like him.
“Not Ace,” the seraphim replied, voice so so familiar, yet devoid of the passion Ace once held, “S-Flame.”
"I'm sorry," he said, bowing his head. "I can't do this."
He couldn’t face this figure. Not now, perhaps not ever.
Spinning on his heels, Luffy raced in the opposite direction. The corridors were a labyrinth trapping him with his past, with his failures. His own tearful face reflected in its walls as he searched for a way back to his crew. His heart pounded furiously and tears stung his eyes. Why would Dr. Vegapunk create these things? Why would the Navy clone Ace when they had condemned him for the very blood they now recreated?
Luffy sniffed loudly, shaking his head as he tried to stop the flow of tears. He wiped them away angrily and walked aimlessly. Now wasn’t the time to break down. His crew needed him!
“Where the heck am I?” he growled, finding himself facing a wall of pipes. Teal fluid bubbled through it, casting the room in a green glow. “Huh, that looks like the stuff the Seraphim have–” he spun around hearing footsteps. S-Flame had followed him.
The seraphim continued to approach, slowly, carefully. It didn't seem to view him as an enemy. Luffy backed up against the wall, feeling the cold metal press against his spine. He was stunned into inactivity as S-Flame reached for him. Small hands touched delicately at his face, a finger tracing the scar beneath his eye.
"You..." Luffy swallowed, "Please, just..." he tried, "Go away..." he whispered.
He begged.
S-Flame tilted his head, observing Luffy's expression and emotion. He grasped Luffy's face, pulling him closer as he leaned in to study him. A warm tongue pressed against his face, tasting his tears. Luffy shuddered. Even his scent; as sterile as it was from his android origins, smelled like Ace.
A tongue pressed close to his lips and Luffy pulled away. “No.. you’re not…” He tried to speak, but S-Flame's lips met his once more and they kissed.
Luffy tried to pull away but S-Flame pulled him closer. Their tongues entwined and their lips locked. S-Flame's feathery wings brushed lightly at his sides. He shivered, a strange feeling coming over him. He wanted to be held by this person, comforted and kissed and caressed. Luffy knew it was wrong. It wasn't Ace. It wasn't his lover, his brother, his dearest friend.
S-Flame pulled away, a string of saliva connecting their lips. He licked his lips, seeming to study the taste and sensations. He licked at Luffy's face again as more tears fell, this time of shame and grief. Luffy wanted to get away, to end this, but he didn't dare raise a fist. His body ached for Ace's touch, his lips.
How long had it been since someone had touched him like this?
Luffy felt a hand on his wrist, gently turning his arm. S-Flame seemed to study him in detail as Luffy was stuck leaning against the wall, unable to help himself. He slid down it to sit as S-Flame poked at the large scar on his chest. Maybe if he closed his eyes, he could imagine those curious hands to be Ace's?
It was a lie though. The hand that touched him was not Ace. There was no warmth, no kindness there. He closed his eyes as S-Flame kissed him again, tongue brushing against his lips and hands grabbing at his face. A warm sensation washed over him and he melted into it, unable to resist.
The kiss deepened, and their lips pressed harder against each other. Luffy could feel S-Flame climb atop his lap, wings flaring as he steadied himself. A hot, hardness pressed against his thigh and Luffy broke off the kiss with a gasp. S-Flame pulled back, his face a mask of confusion. He glanced down, pulling his shirt out of the way. Luffy felt a lump form in his throat at the sight of an erection in the young clone's shorts.
"I can’t do this. Not with you, you’re not…" Luffy was shaking, wasn’t he? The emperor who had gone up against so many powerful enemies, the man who had freed Wano, the pirate who punched a Celestial Dragon was struck powerless against a child.
No, not a child. A clone. A clone of his most precious brother.
His body burned with need and he couldn't think straight. It had been so long since he'd had Ace's taste on his tongue, his touch on his skin. It was wrong but... maybe for a while, he could pretend. Pretend they were teens again, fooling around with one another. Pretend they were forbidden lovers. Pretend Luffy could feel warmth like this again.
Luffy pulled the clone in for another kiss. S-Flame moaned softly as their lips crashed together. He grabbed at Luffy's shoulders, digging his nails into the muscle as if to hold him back from leaving. Luffy couldn't help the moan that left his lips as he wrapped his arms around S-Flame, pulling him close. The seraphim responded by pressing down on his lap.
S-Flame was sitting on Luffy's lap, the man's thigh between his legs. He could feel pressure on his groin and a shiver of pleasure ran up his spine. The clone shifted his position, hips moving against the warmth beneath him. S-Flame gasped softly, feeling a rush of pleasure bloom through him. Luffy could feel how the other tensed and shivered. The seraphim moaned softly into his mouth as their tongues tangled in a heated dance. He felt himself growing hard once more and he shuddered as the warm flesh rubbed against him.
The clone continued to grind against him, first unsure and inexperienced, before pressing down earnestly, chasing the new, lustful sensations that filled him. He had seen other clones have sex before but had never understood the feelings himself. Now he was having them and he felt a fire burn deep within his loins. The thought of being with someone else, of sharing a body with someone else... that felt good. That felt right. It made him feel alive in a way he never had before.
Luffy broke off the kiss, gasping for breath. He moved his hands up to S-Flame's face. The clone froze for a moment. That face… Luffy couldn’t get over it. Luffy had few artifacts of Ace remaining through the years. A few wanted posters, a photograph they all took together in Arabasta. All faded and torn from the years of battle and hardship. His memory of their shared childhood was fuzzy these days. Perhaps, he wanted to forget. To forget the bond they shared.
But he couldn’t. No matter how strong he got, how many friends he gained, how beloved he became, nothing compared to Ace.
Luffy’s finger traced the freckles on S-Flame’s face. He remembered the dark ones beneath his left eye, how they formed the Heron constellation. How did he remember that? S-Flame stared at him a moment, those crimson eyes boring into his before he glanced at the finger and licked it.
Luffy groaned, his cock throbbing. He couldn't stop himself. He felt the clone's heat, wetness rubbing at his thigh as the other pressed against him. But he tasted so familiar. Tears streamed down his face as he continued to kiss, moaning softly into the clone's mouth as he rocked his hips.
S-Flame's cock strained against his clothes as he humped the other, rocking his hips back and forth. It wasn't long before he was grunting, breathless, his eyes narrowed in pleasure. S-Flame let out a whimper, lips parting. Luffy could feel the clone trembling and he didn't care. All that mattered to him was S-Flame's lips on his, that hot, sticky heat. He felt his own member throb and press against the fabric of his underwear. He didn't know how long he would last.
S-Flame pulled away, panting harshly as he wiped his mouth. He was panting; his chest rising and falling rapidly. He reached down, gripping at Luffy's clothes as he pressed himself against the man. Luffy leaned back against the wall, unable to tear his gaze away as the Seraphim got off on him. The clone's wings fluttered, his breathing rough. S-Flame closed his eyes and gripped at the fabric of Luffy’s clothes, body taunt as he came.
Luffy shuddered at the wetness that splashed on his lap. It was so warm, so welcoming. Luffy groaned softly, feeling that heat on his thighs. He pulled S-Flame closer, kissing him hungrily as the clone pushed against him. There was nothing gentle about it. They were both on fire and they needed each other desperately.
For a few seconds–minutes-days–moments, the two tangled together. Perhaps it was S-Flame’s genetic coding, but Luffy felt as though their souls intertwined. The thought of retreating, of returning to his crew and the outside world faded.
Finally, S-Flame broke away, panting heavily. He looked down at Luffy and then growled, a low purring sound, reaching for the hem of Luffy's dress. Luffy gasped as he was upended, hips pulled up by the clone. He had seen firsthand the strength of the Seraphim, but S-Flame had been so gentle with him throughout all of this.
S-Flame had seen S-Hawk and S-Seal do this many times. He knew what he wanted. His mind swirled with many thoughts, confusing, emotional thoughts. But one feeling was stronger than all the others: lust.
"Wait..! This is too far..." Luffy whimpered as he was pressed to the floor. He struggled weakly but found no strength in his body. S-Flame just kept pulling and soon he was kneeling on top of him. This position was familiar– to both of them. Somewhere deep in the Seraphim’s genetic code, perhaps he had a memory of his origin doing this before. That day Ace had taken Luffy beneath the green canopy of the jungle. Here the green was a blue tinted teal, glowing and reflecting off cold metallic walls.
There was absolutely nothing he could do as the clone's cock pressed against him. He was so close already. His heart was pounding and he could barely breathe. He didn't want to look at S-Flame. To look in the wrong mirror of Ace's face, but the seraphim guided his gaze to his with a hand far too gentle. Perhaps if it had been rough, Luffy could get angry, he could fight.
Luffy stared up, those eyes so familiar yet the wrong colour and adorned with a star-shaped pupil. Freckles he'd mapped out and committed to memory-- on darker skin. Luffy whimpered as S-Flame pushed up, hips slotting beneath his and his cock rubbing against the man's entrance.
His mind screamed something, but he couldn't hear it over the pounding of his heart.
"No..." Luffy shook his head, whimpering helplessly. Did he want this? He wanted Ace– he didn't want this fake– but the touch and the scent– Luffy was spiraling. He closed his eyes as he waited for it, the anticipation burning through his body.
Luffy felt a shudder go through the clone's body as he pressed forward. S-Flame grunted, his eyes widening as a gasp left his lips. The tip of his cock pushed inside him and then suddenly a warm pressure filled Luffy's belly. A jolt of pleasure rushed through his system and he shivered. His body trembled slightly and S-Flame growled, looking down at him. He reached down and grabbed Luffy's hands, holding them above his head.
S-Flame started to move and Luffy melted. It felt the same. It was like their first time together all over again. The way they moved together, that incredible warmth between their bodies, that connection was all so familiar. Luffy felt S-Flame's cock throbbing inside him as he pushed deeper. The clone grunted softly, lips close to Luffy’s neck and wings flaring. Luffy felt shame rise in him.
But he wanted it. He was so tired of being alone. He wanted this so bad. He wanted to feel that heat again, the sensation of Ace inside him. He wanted it so badly.
"Fuck me," Luffy begged him, pressing his hips up. "Please..."
S-Flame grunted, pushing himself even deeper. Luffy whimpered as he felt that thick heat spread within him. S-Flame pushed in deep, thrusts clumsy but eager. He pushed into Luffy hard, grunting as he bottomed out. S-Flame's wings twitched and burst into flames, sending a wave of heat over Luffy's body. Luffy gasped, his eyes widening as he felt something else inside him.
The feeling was different from before though. There was nothing gentle about it, more animal than human, but it still made Luffy feel good. He tried to pull away but found himself pinned to the floor, S-Flame's hips grinding against him as he fucked himself into him.
"A-Ace...!" Luffy mewled as he felt it. That burning heat. All the warmth he'd ever wanted, it was pouring out of S-Flame, flooding his body. It was almost painful, but it was better than anything he'd ever felt. As much as he wished to pull away, as much as he wanted to keep his distance, he couldn't stop himself. There was too much pleasure. Too much burning heat.
Luffy felt tears well in his eyes and he closed them, shivering as he was fucked into that cold, metallic floor. The coldness kept him awake, kept him conscious as the heat raged within and above him. “Ace…” Were those Lunarian flames or Mera-Mera? Luffy couldn’t tell. He didn’t care either way.
S-Flame groaned loudly, thrusting deep into Luffy with shaky movements. He kept thrusting, each push forcing a gasp out of him. He threw his head back as he drove into Luffy's body, watching his face contorted in pleasure. Seraphim were not made to breed, to feel such strong emotions, but when one had blood bond, memories from their original, perhaps that was stronger than any programming.
Arms thrown over his face, Luffy cried out. "Ace... more... more...!" His legs seemed to have a mind of their own as they hooked over the clone’s shoulders, opening himself more to him.
S-Flame growled deeply, his hips hitting Luffy with renewed force. He kept going, not even pausing. Each thrust pushed him deeper inside Luffy's body and each one sent another spasm of pleasure up his spine. S-Flame groaned softly, hips rocking faster and faster. He knew exactly what he wanted. How he wanted this to end. And he wanted it now.
Luffy cried out and bit down on this sleeve, gasping as he was fucked harder and harder. S-Flame pushed inside him, bottoming out inside Luffy's body. His warm, rubbery insides accommodate him well. The tightness, the heat, the way he squirmed and begged beneath him. It drove the Seraphim wild.
"S-Flame, please...!" Luffy begged. He was begging. He was begging for S-Flame. Not for his crew to save him, not for Ace. No one else mattered. He was pleading with a clone of his beloved brother because he thought that was all he was anymore. Luffy was a shell, nothing more than that. Just a body. And if it ended here, he was ready for it. It would have been enough. He was so tired of feeling empty.
S-Flame grunted, slamming his hips into Luffy and driving himself deep. There was a sharp growl and S-Flame came, spilling inside of Luffy, hands gripping his hips in a bruising grasp. His wings burst into flames, sending heat all over Luffy's body. It was too much. His brain was swimming and his body was trembling. His heart beat rapidly, his lungs burning as the flame washed over them.
It was Marineford all over again. The comforting warmth of Ace’s Mera-Mera being smothered by the suffocating heat of Akainu’s magma. The splash of boiling blood upon his face, the burning in his chest. Was the wound what burned up that day, or his heart?
S-Flame's wings flared, flames licking toward him. He kept thrusting, not slowing as he spilled himself inside of Luffy, his cock throbbing inside him. They held onto each other, moaning softly and clinging tightly to one another. Luffy ignored the scent of singed clothing as he wrapped his arms around S-Flame, burying his tear-stained face in those pale locks.
He stayed like that for a few minutes, panting and shuddering. Pulled apart and put back together by the pleasure and pain. Memories fuzzy and painful, chest aching with the need for breath and grief for Ace.
S-Flame was still, systems rebooting as he recovered from the shock of climax. He pulled himself out of Luffy, shakily rising to stand and pull his clothes back into place. Luffy whimpered at the loss, falling back against the cold floor, drained of energy and desire.
Luffy stared up at him, gaze blurry with tears and pleasure. He could feel the clone's seed spill out of him, a familiar, oh-so-familiar feeling. S-Flame held his gaze for a moment, then turned away.
"Ace..." Luffy whispered, voice raspy and mouth dry from the heat. He felt tears forming in his eyes, his cheeks wet as he watched S-Flame walk away from him.
He was a clone.
He was a copy.
That was all he was. Just a copy, just a tool. Not a person. Not a brother.
Not his Ace.
Luffy sobbed, curled up on his side, covered in hickeys, cum leaking from his entrance, and smelling of smoke.
And he was alone. All alone.
