Orange light coursed through the aquarium windows. The heavy bass sounded from the room adjacent, causing the ground to shake. Luffy, Nami, Chopper, Brook, Usopp, and Zoro were enjoying the sounds of Sanji’s DJ set, a random skill he acquired in the Kamabakka Kingdom.
Robin and Franky were breathless in the symposium style fish tank, undressing underneath the reflective neon lights.
“They’ll notice,” she whispered.
“I don’t care,” he said, clawing a hand through her svelte black hair. Robin parted his lips with her tongue, matching Franky’s tenacity, turned on by his aggression. This moment won’t last long, he thought. Sweat appeared along Robin’s hairline. Her moans deepened alongside the electronic music. She lunged at him, pressing her lips to his. She wrapped her arms around his barrel-like neck.
Franky sat back and let her take control. The song switched up, a fast-paced techno beat that put him in a trance. He bobbed his head faintly, then swung it wildly when the beat dropped. He wrapped his massive hands in Robin’s hair again, making a true mess of it.
Robin stradled Franky’s gigantic torso, her legs nearly split. Everything in her was telling her she needed this. They haven’t fucked in so long, but the music Sanji played made her feel like the night would never turn to day.
“I missed you,” he said, cupping one of her full breasts. The soft flesh barely funneled through his thick fingers. He used an ounce of his strength to bring her closer to suck on her perfect, pointed nipples. He placed his other hand on her bare ass, kneading, forcing her asshole to wink. “I want to feel how tight you’ve gotten.”
Robin moaned his name, pushing her hands down to feel his erection. The music eased for a moment and the song ended. Their pants echoed in the empty hall until lyrics filled the air. Robin smiled for a moment before she leaned in for another kiss.
She danced on his lap, grinding her hips back and forth in the air while she fiddled with his belt.
“Franky, why am I the only one naked?” she asked, eyes shining.
“I’m sorry,” he apologized. What else could he do? He lifted his backside and watched as Robin slid off his red spandex. Her eyes went straight to his cock. She couldn’t grip it with one hand, no, she had to use both hands to wrap around it, just to hold it steady. The music egged her on. The synth waves made her lips curl up. A dominating energy radiated through the Sunny. She swallowed him.
Robin never liked being called names. During sex, on the street, in a fight. But right now, she felt dirty. Her hair looked like a beasts’, ragged and knotted in the back from Franky’s grip. Her face bore a scarlet flush and she was smiling like a madman, bouncing on her toes. She took him in deep and held his quaking gaze. She wanted to be called a whore, but Franky would never do it.
“Franky,” she asked, coming up for air. She gave the tip another lick before she spoke again. “I want it rough tonight.”
Franky seized. He’d always imagined a girl saying something like this to him. Franky, spank me, Franky, choke me. Never in his life he’d imagine it’d be someone as fine as Nico Robin. Never someone as cool or even as smart as her.
He wasn’t going to let this opportunity pass.
He shook off his nerves and showed absolute, brazen confidence. He sat up a bit, making Robin appear even smaller than she already did. She seemed to cower slightly and he loved the show of it all.
“Oh yeah?” he rolled his words, drawing Robin nearer. Her breasts sat against his cock, sheen with spit and coated with shiny strings. His eyes took in the image of her face, her chin a waterfall of saliva and precum. Her big, opal eyes reflected the blue of the water around them.
He could talk a big game, but acting on the other hand would be tough. He was admittedly hesitant to palm the back of Robin’s head, even more hesitant to guide her tongue down the slope of his cock. He winced as she strung up and down the sides, asking him through her downcast eyes, does this feel good?
He nodded even though she did not say anything out loud and he kept nodding, watching her devour him with his help. When his cock hit the tightest part of Robin’s throat she gagged. Franky jumped up.
“Robin!”
She paid no mind to Franky’s exclamation. She lowered her ass onto the floor to compose herself, feet splayed to one side. Her posture was less than perfect. Her stomach showed soft rolls as she sat and cleaned her chin with her wrist. Franky couldn’t resist. He leapt up off his wooden seat and clambered onto the ground, moving awkwardly but with rapid speed. He surrounded Nico Robin, casting a wide shadow above her.
He was determined to look at her blushing face for as long as time allowed. Without turning his gaze he hiked her legs all the way up towards her head. Robin’s moans filled the empty gaps in the blasting music. The sounds were tropical now, reminding her of carefree times. She felt the cool, scratchy carpet on her back, keeping her in the present.
Franky was glad he built touch sensors into his body. It was what he missed the most about his robotic structure when he was left without. It took years, but he was finally able to touch the grand, umber wood of the ship he built. To actually feel the carvings in the planks, to remember what a splinter felt like. It had been so long since he had Robin underneath him, so long since he’s felt the warmth of her skin.
He trailed his long fingers along her milky thighs, watching her delicate skin softly concave. He gripped them tighter, the flesh seething through his shaking hands. He bent down and covered her stomach with his face. He stuck his tongue out and spread its wide base over her belly button, the music in his head fading to amplify Robin’s sweet screams as he licked.
He kissed the brown-butter beauty marks that made a faint constellation along her hip bones. He tasted the scar along her side, a wound from who-knows-where, much too big for his liking. He spent some extra time there, breathing life into the jagged, nude abrasion.
The faint smell of sex radiated from Robin’s core. He was so close. He felt her pubic hair on his spiked chin. He kissed the clear spot between that beautiful black forest and her torso before moving down.
Robin jolted. It was a feeling she’d never grow used to. Franky was impossibly skilled at eating her out and she had forgotten exactly how long it’s been. Unlike herself, Franky wasn’t putting on a performance. He was a blue collar man, down to do the job and do it well. His hands were hooked soundly onto Robin’s neverending legs, keeping her imprisoned in his grip. His head was bent and his eyes were closed. He moaned as he licked using his whole tongue, which fared larger than Robin’s entire waist.
Her body rose up onto her elbows, running from the sensation. She wasn’t going anywhere. Franky had her anchored onto the floor, his tongue unforgiving.
“It feels good,” she managed, sending two fingers up to twist a nipple.
“That’s good,” he answered, tugging harder on her hips, bringing her thighs closer to his cheeks. The music that had been blaring so seductively before completely faded in his mind. He could only taste the sweet offerings in front of him, he could only take in Robin like this, with nothing else clouding his thoughts. He peered up once, afraid he couldn’t take it if he held the sight. She was breaking. Her chest, her nose, her ears rang with sweat. She quivered. Thick strings of matted hair stuck to her skin. Her ample chest rose and fell rapidly. Her lips spread into an o.
Franky’s cock throbbed as she came for him, his own moans adding to her pleasure. He loosened his grip as her body physically vibrated. She spoke the most he’s ever heard her speak.
Fuck, fuck, oh, fuck. Franky…
“Was that good?” he asked, his chin lacquered with cum. Robin answered his question by ambush, feasting on his face, lapping up the taste of herself.
“It was so good,” she said, silky hands framing his face. “I want to feel your big cock, Franky. Will you let me?”
He answered her question with more hesitance. Her frame was so much smaller than his. He ached for it, the pulse between his thighs prominent and pushy.
“I told you,” she said, right up against his big ear. “I want it rough.”
Franky forced his tongue into her throat. He needed to feel her, needed to see the expressions on her face with his fat cock spreading her open.
“I want to see your tits,” he said, leaning back onto the wooden pillar in the center of the aquarium.
“Yeah? You want my tits in your face?” she repeated, placing her doll-like hands on his tank-like chest. She climbed on top of him, granting his wish.
He was content just staring, but then he remembered her voice. I want it rough.
Franky struck Robin’s breast, faintly changing the pigment of her skin. He struck it again, making her cry out.
“Oh, yeah,” she said, biting her lip. Franky smiled.
He was getting the hang of this. Robin was grateful. She hadn’t had this much fun during sex since the last time they fucked, but even then Franky was too mild-mannered. She had to physically place his hands on her, she had to guide him to the good spots. She made sure to tell him, it’s ok, and even then he’d say, are you sure?
“I’m happy we’re on this ship,” she indulged with a giggle. Franky couldn’t believe how lucky he was.
He watched in awe as she took the head, sinking down onto his dick slowly. It stretched her out definitively, in a way that he could see it happening. His eyes rolled back into his head and her stomach clearly bulged. There was no way she could take all of it, but she tried.
“R-Robin,” he strained, the words barely coming out. She was squeezing him so tight he couldn’t bear to even watch, afraid he’d come the minute he saw her face, scrunched like a washboard with so much determination. He’d flood her insides. Not yet.
“Franky, you’re so big,” she gasped. She was half up half down, squatting gently onto Franky’s thick cock. “I feel it.”
She kept sinking, deeper and deeper, until Franky couldn’t believe she was wrapped around it all. He longed to cling to this feeling, to remember how it felt to be inside Robin, to be close with her like this.
Both Franky and Robin were nearly in disbelief. Robin couldn’t believe she took this cock before, and she couldn’t believe she was taking it again. This position though, it wasn’t doing it.
“Franky,” she said. “Pound me.”
Franky rolled his eyes. He was at his limit with surprises and the next thing out of Nico Robin’s mouth tonight could very possibly kill him.
“You’re super fucking sexy,” he said, unable to think. The heavy bass came back. He was being given energy through the music, the added chemistry unshakable. He bent his knees, sending Robin forward. She exclaimed as he went deeper, if only for that moment. He groaned at the added pressure. He gripped her entire torso with one hand and caught her eye. He nodded. She smiled.
He started. Robin felt shy in front of all the fish. She shook away the silly thought, sending her attention back to Franky. She wasn’t going to break, but she appreciated how thoughtful he was being. His eyes were stark but kind, he was trying his best at playing the role Robin wanted. She could hear the unflattering noise from below, embarrassed at how wet he’s made her.
She reached out and scraped along his abs, the muscle hard like steel. She could feel him flex as he thrusted into her. She clung onto the sounds of the pop music, using the rhythm as a guide. She was back to performing, swinging her hips wildly to the beat of the drum, mouthing the easy words of the chorus. I need you.
She moaned when the beat dropped, sending herself forward to stick onto Franky’s large chest.
“Fuck me,” she breathed. “Fuck me, fuck me, fuck me.”
Her instructions were simple. She wanted him to feel the pleasure she felt on her own. Come around his cock, she told herself. She moved her ass with purpose, up and down. She rose to meet Franky’s eyes, completely glazed over, watching Robin bounce.
“I wanna come,” she whined.
“Come,” he told her, bringing her forehead to his. “Then come.”
He held her there, inches from her face. Robin kissed him, but it wasn’t so much a kiss as it was an attempted suffocation. She buried him with her tongue. Franky idled, drool pooling in the sides of his mouth as Robin went at him. He couldn’t last. Not without a condom.
He struck Robin’s thick ass, turning it red. She bounced harder. Her breasts hung like bells, gravity pulling. Franky didn’t know where to put his hands. He sent his head back, then forward, desperately trying to make a decision.
“Robin, I’m —”
“Me too,” she said, bringing a hand down to her center. She found her clit and added some pressure. “Franky, my ass.”
Franky’s look gave her pause. His eyebrow was hiked, clearly confused. She grabbed his hand and placed it into her swollen cheek. “Please,” she sighed.
Franky slowed his thrusts to concentrate on Robin’s backside. He lobbed some spit onto his smaller hands’ finger and sent it behind her.
Slowly, he entered her smallest hole. She made a sound Franky’s never heard before.
“Robin, come for me,” he begged, his voice high and needy. She rocked onto his finger and his cock in one swift movement. He bent his hips up and filled her, satisfying Robin to her core. She stuck her index finger into Franky’s open mouth, grinding to the beat of the heavy bass in the background.
Franky sucked on her finger like it was cherry flavored, his eyes glassy and wide. Robin ached, finally feeling that intense flow of adrenaline she felt being eaten out. She took her finger away from Franky’s disappointed face and brought it down to her center. She pressed in. She moaned. She sent her body up and down, the crash of her thighs sounding off as she did so.
She didn’t know when she was about to come. She couldn’t announce it. She could only feel her body seize. She was truly free, her body limp and accepted as she was. She leaned down onto Franky’s chest and she listened to his heartbeat as she convulsed on top of him.
“I’m gonna come, Robin,” he said, pulling her out of her daze.
“I don’t want you to stop,” she said.
Tell me about it. He brought her head in close.
“Don’t pull out,” she said.
Thankfully she didn’t see Franky roll his eyes a second time. It wasn’t just the things she was saying, it was the way she said them. Her velvet voice, without tone, without judgement, just fact. She never minced words. She always meant what she said.
“I won't,” he promised.
He fucked her like that, body to body, chest to chest, until he held her in close, moaning into her ear, I’m coming. He held them like petrified lovers, keeping her full until she was satisfied.
There was no more music. Robin wondered how long it had been that way.
