“It seems like everyone is occupied for the afternoon,” Robin said, eyes closed and hands crossed over her chest as she covertly observed the rest of her fellow crew members from the safety of Franky’s below-deck workshop.

”Suuuper!” her cyborg companion exclaimed. “It’s been too long since I’ve had you all to myself!”

Franky pushed his sunglasses up onto the top of his head, giving the raven-haired woman a wink. Robin smiled at him as she uncrossed her arms, but kept the eyes and ears she had just summoned all over the ship on alert. One could never be too careful living in such close quarters with nakama who refused to knock before entering a room.

While the relationship between Robin and Franky was no longer secret, they still had precious little time to truly be alone together, privacy on the ship being fleeting at best, but usually nonexistent. Today was a rare opportunity where everyone seemed engrossed in their own tasks that would keep them all busy for the next several hours, and the archeologist knew exactly how she wanted to spend that time.

It seemed Franky had the same idea since he walked over to the large metal cabinet that was nearly as tall as he was. He pressed the heel of his hand against a hidden sensor hidden somewhere along the top, the corresponding sensor in his own hand beeping in response. The entire cabinet rumbled and then disappeared down into the floor, revealing the hidden panel behind it.

Before they had started dating, the shipwright’s most secret projects were hidden here. Blueprints and weapons and other creations had been locked up tight, unknown to even the other members of the Strawhat crew. However, now that he was intimately involved with the ship’s resident historian, he had filled the secret storage space with perhaps his proudest achievements of all.

“Aow! So what are you in the mood for?” Franky asked, stepping back to let Robin peruse her options.

Before her was an array of hand crafted phallic attachments in every size and shape imaginable. They ranged from the benign to the downright exotic, and while Robin was the only woman to see them put to use, there was truly something here for everyone, no matter their taste or preference. Fortunately, her preference was the only one that mattered to the blue haired man, and she happened to be as adventurous in bed as her free spirited-partner.

It was no secret the flamboyant man was a master shipwright and even more skilled in making modifications to his own body. He had installed enough weapons in his arms and shoulders to outfit a small battalion, as well as making himself bigger, taller, stronger and able to change his hairstyle with a single tap to his prosthetic nose.

Given his proclivity to upgrade his body with cybernetic enhancements, it was no surprise he had also sought to upgrade his own manhood in a variety of ways.

Robin ran her hand along one of the attachments thoughtfully, it was comically big and incredibly veiny. She had sampled it before, but decided she didn’t want to spend the time she would need prepping her body enough to take something so big. She was in the mood for some instant gratification. Her fingers hovered over an attachment with a ribbed texture, then one that spiraled like a unicorn horn, only it ended in a bulbous head rather than a tapered tip. She had tried them all in the past, enjoying what each had to offer, but she had her sights set on something very specific.

Her trailing fingers stopped at one of Franky’s newer creations, one that had quickly become one of her favorites. While it wasn’t much longer or thicker than the original anatomy he had once had, it had an exaggerated curve that hit her most sensitive places perfectly. It also had a feature she had come to adore.

She plucked the phallus from where it was showcased and pressed a hidden button at its base. It immediately began to vibrate, emitting a low drone as it shimmied in her hand. Another press revved up the intensity, the buzzing sound rising in pitch as it tremmored even faster. Another press changed the vibrations to short, staccato pulses, another to an undulating wave of fast, then slow, then fast again.

Robin thumbed the invisible button once more and the penis attachment quieted as it grew still.

“I think this will do just fine,” she said, turning to Franky with a coy smile.

The cyborg’s megawatt grin could have powered the entire ship as he laughed.

“Someone is super impatient today!” he guffawed, knowing this particular attachment would take Robin to the edge quickly, efficiently, and probably multiple times.

“Can you blame me?” she giggled softly behind her free hand at his enthusiasm. “It’s been weeks since I’ve been able to get my hands on you.”

As if to emphasize this point, several effeminate hands sprouted from his body, caressing him provocatively. The arms that had sprouted from his thighs reached for the waistband of his trademark red swim trunks, edging them a little lower on his hips.

She stepped forward, handing him her penis of choice before reaching for him with her two original hands. Even though Robin was taller than the average woman, Franky’s modified body towered above hers. He bent to accommodate her, leaning down so she could cup his face gently and capture his lips in a kiss.

She sighed softly into his mouth as her tongue ran along his. It had been too long since she kissed him deeply like this, choosing to keep their public displays of affection to a minimum, especially in the presence of innocent eyes like Chopper’s or jealous hearts such as Sanji’s. Now that they were alone, she could show him just how much she wanted him, devouring his mouth while her conjured hands roved over his body. Mischievous fingers slid under his open shirt and caressed the dual scars running down the length of his torso. The hands that had already had a grasp on his briefs succeeded in pushing them over his hips and down his legs, letting his default penis spring free. It was already hard and ready to go but it would only take a moment for the shipwright to swap it out with the chosen upgrade.

He chuckled against her lips, amused by her eagerness as one massive hand rested on her hip, nearly encircling her whole waist with enormous fingers. He sought her lips just as hungrily as she did his, pulling back only when she gave a playful nip to his lip.

“Aow! You know I like it when you’re feisty!” he declared, picking her up and setting her on her workbench as if she weighed nothing at all.

“Well, Robot-san,” she teased, resting her hands against his chest. “If you don’t hurry up, you’re going to see just how feisty I can be.”

To emphasize this, one of her summoned hands gave his now naked ass cheek a slap that made him jump in surprise.

She let her nails rake lightly down his pectorals, reveling in his stupefied expression and she dropped her voice to a sultry murmur. “Now, why don’t you slip into something more comfortable?”

Regaining his composure, he smirked at her, plucking his sunglasses from his head and laying them down on the work surface next to her.

“You’re suuuper naughty today, Robin-chan,” he grinned. “I guess I’ll have to fuck you extra hard to make up for it.”

The archeologist let her hands drop from his chest, bringing them to the zipper pull of her collared crop top. With one tug, the two halves separated and her ample chest spilled forth. She shrugged out of the top completely, well aware that her lover had gone very still, his eyes no doubt glued to the flesh she had just revealed.

She folded her discarded clothing calmly, setting it down to join his sunglasses before leaning back to brace her weight on the workbench’s hard surface. She looked up at him, a challenge in her deep blue eyes and a playful smile on her lips.

“Do your worst,” she purred, knowing that Franky had soundproofed his workroom after he discovered how loud she could be when he had her bent over this very bench. Now she could scream his name as loud as she wanted and none of their companions would hear unless they were right outside the door.

Robin dispelled all of the hands that had been groping him in a shower of sakura petals. The action seemed to shake the cyborg out of his daze and he released her waist to reach for his member. He grasped it firmly and gave it a quarter turn to the right. Ordinarily, this would cause the attachment to release and he could remove it and snap a new one in place. However, his dick had chosen this inopportune moment to become stuck, failing to release like it should.

After several attempts at twisting and tugging, he looked up from his crotch to give Robin a sheepish grin.

“Looks like there’s a malfunction, but I’m sure I can fix it. Be back in a sec.”

He pushed away from the workbench to rummage through a pile of odds and ends behind him, no doubt looking for a particular tool to fix his performance issue. Robin watched him with an amused smile. His back was turned to her but judging from his annoyed grunts and the wrench he was brandishing, the fix would not be as easy as he initially thought.

Oh well, there was no reason she shouldn’t start without him, right?

Since his back was turned to her as he struggled with his personal issue, he didn’t notice Robin summoning a new arm, this one directly out of the storage cabinet. The hand nimbly grabbed a phallus that was long and studded, rubbery nubs scattered along the entire length. The sensation caused by the texture was both unique and pleasing, especially when it moved inside her at a slow pace so she could feel the studs slide against her intimately.

The hand holding the attachment tossed it to her and she caught it easily. She used her free hand to deftly undo the tie of her sarong-style skirt,letting the fabric fall open to reveal a barely there thong of violet lace. Franky continued to trouble-shoot his faulty body part, grumbling as he abandoned his wrench in favor of a hammer, oblivious of the devious actions of the woman behind him.

Robin brought the studded attachment to her lips, letting her tongue swirl around the bulbous head before sliding several inches into her mouth. Their playful banter had aroused her, but not enough to produce the lubrication she needed. Franky was always quite generous with foreplay, but they hadn’t gotten that far before his dick went on the fritz. Fortunately, a little saliva was all she needed to rectify the problem.

Making sure she got the faux-skin good and wet, she pulled the cock from her mouth and used her other hand to tug the crotch of her panties to the side, too impatient to try and take them off while sitting on the workbench. She brought the impromptu sex toy to her opening, rubbing it up and down her slit experimentally before pushing the tip inside and let out a soft sigh as her body parted for the intrusion, the lubricated head slipping inside easily.

Franky must have mistook her sigh for one of impatience.

“Sorry love, I’m almost done,” he said, attempting to placate her without turning around. He was now hammering at his crotch with alarming force, but the cyborg appeared oblivious to any pain. He must have disabled all nerve endings in the area.

Robin bit her lip as she pushed the cock inside a couple of inches, reveling in how the raised studs slid against feminine walls.

“Mmm, it’s alright,” she responded, managing to keep her voice fairly even. “Take your time.”

With one more push, the dildo was lodged within up to the hilt and she flexed her body around it experimentally, biting her lip to keep from moaning aloud. Squeezing down on the cock inside her only made the texture even more apparent and she loved how it seemed to massage her from the inside.

Slowly, she withdrew the length a few inches, allowing her body to grow accustomed to being filled. She soon fell into a languid rhythm, sliding the appendage back and forth, in and out, feeling her sex grow wetter with every pass as the little studs worked their magic.

Her head tipped back, long raven hair spilling down behind her as her eyes drifted shut. She swallowed down her moans, keeping silent except for a slightly shuddering breath. If Franky were to turn around and see what she was up to, he would become so distracted, that he would never manage to get his personal problem sorted.

She let her hips tilt, leaning back on one hand so she could get a better angle, her body accepting the phallus even deeper than before. She increased her pace just a little, noting she was slick enough now to take the toy with little resistance. The historian could feel moisture start to leak down onto her thighs and was surprised that the subtle sounds of wet suction had not yet caught her partner’s attention.

“Ah ha!” the cyborg cried in triumph, as if on cue. She heard the distinct sound of his cock disengaging with a click and then a similar sound as the new one replaced it.

“I figured it out!” he crowed as he began to turn around. “The spring loaded mechanism had jammed, so all I had to do was–”

His technical explanation died on his lips as his eyes took in Robin’s nearly nude form, thighs spread wantonly and legs dangling over the edge of his workbench as she worked one of his attachments in and out of her now-dripping core.

His jaw dropped, mouth hanging open as he watched her silently, while Robin gazed back provocatively. She commended herself for being able to leave the man speechless because it was a rare day indeed when Fanky was too stunned to speak.

“Suuuper,” he finally managed softly, his tone irreverent as his eyes remained fixed to where his hand-crafted cock was disappearing inside her.

Robin had only meant to warm herself up, to appease the ache that their playful banter had induced. But the way his eyes were roving over her hungrily, drinking her in as if she were a living goddess, was making her feel empowered and a little daring. While it wasn’t the first time she had touched herself in front of him, she hadn’t previously used one of his phallic creations unless he was attached to it. Since he seemed so riveted by what she was doing, she might as well put on a show.

She pushed the studded cock inside her as deep as she could take it, moaning softly at the satisfying way it filled her up. She arched her back, jutting full breasts forward while leaning back on her free hand. As she continued to drag the toy in and out of herself, she bit her lip and shot him a sultry look that made the cyborg groan aloud.

“Goddamn, Robin,” he breathed, making his way towards her, his large hand closing around his cock to fist over it slowly. Since his interchangeable penis attachments had been made for the sole purpose of having sex, they were already rigid so there was no need for him to pump himself in order to get hard. That meant he must have reengaged the nerves along his new cock and was now masturbating to the sight of her shamelessly spread out on his workbench. The thought gave her a thrill as he came to stand before her, leaning down to watch the way her body contoured to the dildo’s studs, the texture briefly visible beneath the petals of her labia before disappearing inside of her.

For a moment he just watched her, enraptured by how she was fucking herself. At last he came to his senses and looked up at her, a cocky smile on his lips.

“I was planning on eating your pussy until you were good and wet but it looks like you’ve got that covered.”

Robin hummed in amusement, her breath made a little erratic by her desire.

“You know I would never deprive you of a meal, Franky-kun.”

Keeping blue eyes locked on his, she slowly, deliberately withdrew the cock from her body, raising it to her lips where she licked it from base to tip, tasting herself on the synthetic skin.

A feral growl escaped the man as he surged to his full height, grabbing her face in both hands and kissing her in a fervor of lips and teeth. He groaned as he tasted her, the spicy-sweet musk of her body lingering on her tongue.

When he finally broke away, he looked down at her, wild-eyed and ravenous.

“I never thought I would find a woman who was as freaky as me,” he chuckled lowly. “Especially not one who also happens to be smart, powerful and so damn sexy it hurts.”

He took the phallus from her hand, bringing it to his own mouth and giving it a lick, tasting the juices it was saturated with.

“Or one that tastes so fucking good that even cola can’t compare.”

“Oh, that’s quite a compliment,” the historian breathed as he set the studded phallus back down on the workbench and crouched between her legs once more. She had felt her body clench achingly around nothing now that her core was left empty, and the sight of her lover licking her slick off the sex toy made her needier than ever. She would have been perfectly happy with Franky filling her up with his now functioning cock, but she meant it when she said she wouldn’t deny him if he hadn’t yet had his fill of foreplay. The cyborg was rather adept with guns and lasers and missiles, but he also had a wicked tongue and extensive knowledge of how to use it.

He effortlessly tugged the last bit of clothing off of her, the lacy scrap of her panties sliding down her legs before being cast away somewhere into the corner of his workshop. He brought his face to her center, observing how she was already slick and swollen, her normally tight slit gaping slightly after being fucked open by the thick dildo. He breathed her in for a moment, delighting in her musky spice before delving in, letting his tongue slide through her folds and into her slick opening.

Robin let out a sound that was something between a moan and a sigh, one hand combing through his trademark pompadour before gripping the thick blue strands. Her enthusiasm for his touch drove him on and he wasted no time sucking at her labia, licking up her juices, and letting his tongue glide over her swollen clit that until now, had remained untouched.

She cried out as her nerve endings flared to life as he made contact with the sensitive pearl. Seeing how she reacted, he focused his attention there, catching her clit between his teeth gently and tapping his tongue over it, driving her wild. Robin moaned and squirmed, her grip on his hair tightening as her thighs quivered around his shoulders. Her previous self exploration had already primed her body, but the way he was assaulting her most sensitive place was overloading her senses. He momentarily released her clit, only to thrust his tongue back inside her, slurping hungrily like he meant to drink every drop. Franky ate pussy like he did everything else, with boundless enthusiasm.

“Mmm, that’s good,” she cooed as he twisted his tongue inside her, hips bucking of their own accord as she sought further stimulation.

He chuckled against her wet flesh, the vibrations feeling delicious against her most sensitive places. He focused his efforts on her clit once again, this time letting the flat of his tongue pass over it slowly as he brought a finger to her weeping entrance. He pushed into her slowly, giving her body plenty of time to adjust to the thick, unyielding metal of his finger.

Her deep moan assured him she was enjoying being filled as he continued to let his tongue sweep over her leisurely. He slid his digit inside her to the hilt, relishing the way feminine walls fluttered around the intrusion.

He began to move, pumping in and out of her at a languid pace, his tongue moving in time over the swollen bundle of nerves at her opening. Robin let out a whimper, the intense stimulation at a gentle pace being too much and not enough all at once. The hand in his hair tried to guide him into a faster pace but he resisted, taking his time exploring her sex both inside and out, but the next time his finger filled her deeply, he crooked it just so, rubbing a place within her that made her soft sounds of pleasure spiral into a high, desperate moan.

The cyborg shifted his eyes up to where her head was thrown back, eyes squeezed shut and lips parted. He was quite sure there was no sight sexier than Nico Robin lost in her own pleasure. He repeated the action, giving her clit a soft suck as his thick finger hooked upward inside her, extracting a similar sob of need as blue eyes fluttered open to meet his gaze.

“Okay?” he murmured against her skin, always making it a habit to check it with her during their coupling. Now that his body was so much bigger, and in some ways more machine than man, he was always careful with his lover’s smaller form. Though she was strong and always amazed him with how much she could take, he never wanted to cause her any pain, unless it was the sexy kind, of course.

Robin nodded emphatically, indicating she was more than okay.

“Want you inside me now,” she breathed, impatiently tugging at blue locks as she tried to drag him from between her thighs back to his full height.

Franky smirked, having no intention of finishing his meal just yet. In fact, he had only begun and didn’t plan on stopping until she was coming all over his tongue.

“Not yet,” he growled, sucking at her pearl once more, earning him a surprised cry. “Wanna keep tasting you.”

He began to move his finger faster, angling it inside her to hit that secret place with every thrust. His tongue flicked against her clit with practiced ease, causing the archaeologist to at last release his hair as she collapsed back with a shuddering moan. Flat on her back now, Franky used his free hand to press one thigh open, spreading her as wide as possible as he continued to lap up her sweet juices. She was impossibly wet now, dripping onto the workbench below her and onto his lips and chin. He groaned into her juicy cunt, inhaling her musky scent like it was the world’s most alluring perfume. He knew there was nowhere he would rather be than with his face buried between Robin’s creamy thighs. He could keep this up for hours if she let him, his stamina unparalleled thanks to an artificial respiratory system and mostly synthetic muscles. However, he could feel her clenching down around his finger with every thrust, every crook of his finger making her body spasm in a way that betrayed how close she was to her climax.

Her small hands grasped the edge of his work table on either side of her splayed thighs, gasping and sobbing as he drank his fill. This was not the first time he had reduced her to a whimpering mess with the talents of his mouth, but she had never fucked herself thoroughly with an artificial cock before he’d done it. She felt feverish and raw, aching to be filled by the big, vibrating phallus she had selected, but also already so overstimulated, her mind was swimming in a hazy sea of pleasure.

The concentrated sucks to her clit made her want to squirm away at the intensity, but the way his thick, red finger massaged her inner walls left her boneless.

“Franky, please,” she whined, not sure if she was begging him for more or for mercy.

In the end, he rewarded her with both, releasing her clit from its sweet torment and increasing the speed of his finger within her, stimulating that spot over and over until stars exploded across her vision and her piercing cry rang out against the sound proofed walls.

Her lover had a front row seat to the way she clenched hard around him before her body dissolved into uncontrollable tremors, flexing and quivering erratically as a gush of sweet honey leaked from her, dripping down his wrist to puddle on the floor.

“Suuuper!” he groaned, watching her make a mess of his workstation. He loved to make her squirt, gauging the intensity of her orgasm by the amount of wetness he could extract from her. Judging by the juices still leaking from her, it had been one hell of a release.

She gasped as he pulled his finger free, her sex feeling puffy and tender after his relentless attack on her body. She tried to catch her breath, breasts heaving as Franky at last straightened to his full height, running his hands up her still trembling thighs to hold her waist gently as she came down from her high.

He smiled down at her, admiring the flush of her bronzed skin and the thin sheen of sweat that made her glisten. She was so damned beautiful, especially in the haze of the afterglow and it still mystified him how she had chosen him over anyone else to be her partner.

Her eyes at last cracked open as she offered him a knowing smile as she released her grip on the lip of the workbench to smooth her hair away from her face.

“From the way you’re grinning at me, I would think you were the one who had just had the incredible orgasm, not me.”

Franky chuckled, bending at the waist to lean over her prone form.

“How could I not grin like an idiot when you taste so good?”

He scattered soft kisses from her bare shoulder across her clavicle.

“And smell so good?”

His lips trailed along the column of her neck, pausing to suck playfully at her pulse point.

“And look so good when you’re so wet and messy and perfect?”

He pressed his mouth to hers, his kiss soft and gentle as Robin let graceful fingers trail along the hulking expanse of his neck and shoulders.

“Flattery will get you everywhere, Robot-san,” she murmured against his lips, calling him by the playful nickname she used so often when they were alone.

She conjured an arm out of the workbench that reached for the cyborg’s artificial member. She grasped him with the devil fruit hand and pumped him a few times, her movements slow and firm.

He hissed out a breath between clenched teeth before laughing shakily.

“Aow! You sure recover fast,” he marveled as slender fingers slid up and down his length, teasing and tantalizing him while Robin’s own hands still rested on his shoulders.

“I think we’ve had enough delays, don’t you?” she said innocently. “After all, our nakama won’t stay busy forever.”

“I suppose,” he acquiesced, straightening to his full height and watching as her summoned hand aligned the blunt head of his cock with her opening. “After alI, I did promise you an extra hard fucking today.”

He slid his length along her slit a few times, groaning at the feel of how slippery and heated she was. When his tip notched within her, her guiding hand shimmered out of existence in a shower of soft pink petals.

He met her indigo gaze, silently asking for permission to proceed. When she nodded, he pushed forward slowly, sighing her name like a prayer as he was enveloped in a silky, pulsating paradise. She flexed around him deliciously, easily accommodating the intrusion that was both thicker and longer than his finger.

Robin whined softly, wrapping her legs around his hips and crossing her ankles behind him as she arched up, hands clutching him as she anchored herself against the sensation of being filled so completely.

He began to move, his rhythm unhurried as he watched his cock disappear inside her, only to emerge glistening and slick with her desire. Her waist looked so tiny in his grasp, his massive hands nearly encircling her completely as he held her steady as his hips ground against hers. This ravishing woman with incredible power and a fearsome bounty was letting him hold her down and pleasure her body. The control she let him wield and the trust she had in him to do so was a heady combination, and he would never take for granted the true gift of her affections.

While the studded cock she had used had felt good, the one in her now felt even better, the wicked curve rubbing all the right places as he slowly dragged it in and out of her aching body. She was thankful for his slow pace, knowing he could piston his hips like a jackhammer if he wanted. The large man had always been generous in bed, seeming to derive more pleasure from watching her unravel than from his own release. Despite his boisterous personality, he was always patient and gentle when she needed it, and he seemed to sense that right now, his slow, sensual movements were currently preferred to a rough pounding. Although, there was one thing he could do that would certainly amplify the pleasure she was currently feeling.

“Franky,” she breathed. “Turn it on,”

He laughed softly, his breath catching as she squeezed down on him especially hard. He didn’t need an explanation as to what ‘it’ was. He simply reached down to the base of his member, thumb pressing the invisible button there. Immediately, his length began to vibrate, the buzz muted while buried in her body but still audible. Robin immediately moaned, stretching her arms overhead to grab the edge of the workbench above her, body quivering as the vibrations reverberated through her.

“Suuuper,” Franky growled, the tremors affecting his own body as well, making his balls tighten and sparks of pleasure radiate up his cybernetic spine. Robin looked so good laid out beneath him, squirming and panting as he continued pushing into her, filling her to the hilt with every thrust.

The trembling phallus inside her felt incredible, lighting up every nerve like fireflies on a summer night. Her thighs squeezed his waist tight as she tried to absorb the pleasure flowing through her, making her extremities tingle and her nipples tighten until they were diamond hard. Either Franky noticed her body’s reaction or simply found her dusky breasts too tempting to resist. He bent over and captured a plum colored nub with his mouth, sucking hungrily while one massive hand reached up to palm the other. Despite the unyielding metal of his hands, it still felt so good when he kneaded and squeezed her breasts.

“Yes,” she whimpered when he scraped his teeth over her pebbled nipple. “Harder!”

Unsure of whether she meant his mouth or his pelvis, he gave her both, biting down on her breast with just enough pressure to make her back bow while simultaneously thrusting into her with a little more force.

Her broken cry told him that she rather enjoyed what he was doing and began to pump his hips a little faster while switching to her other breast, licking and sucking as if he meant to devour her.

Robin gripped the workbench desperately as she was swept away on a tide of pure sensation, the cock inside her buzzing on monotonously as he quickened his rhythm and mouthed at her sensitive nipples. Her body thrummed, synapses sizzling, and yet Robin wanted more.

She released one hand’s iron grip on the lip of the workbench to fumble blindly for the cock pistoning inside her. Franky paused long enough for her to grasp him. With a single press, the vibrations inside her increased, his attachment shimmying even faster as the buzzing sound rose in pitch.

Robin moaned throaty and low as the oscillations inside her increased. Franky resumed the movement of his hips, releasing the captured nipple from his lips to offer her a grin.

“You really are impatient today, aren’t you?”

The archaeologist couldn’t disagree. Now that her body had acclimated to the feeling of being stuffed so full and the relentless vibrations inside her, her body was revving up quickly for another release and she welcomed it greedily.

Rather than answer the cyborg verbally, she used her devil fruit powers again, this time summoning nearly a dozen arms that sprouted from the workbench’s surface as well as Franky’s own body. The fresh set of hands wasted no time roving over Robin’s body, fingers plucking at her abandoned nipple, caressing her neck, smoothing over her taut stomach, all while the shipwright’s pumped into her at a quickening pace, his hands falling to her hips to hold her steady.

He watched as one hand trailed down to the place where their bodies met, finding her swollen clit and rubbing it gently with feminine fingers.

“Aow! That’s so sexy! I love it when you get freaky with your powers!”

Robin was well aware Franky enjoyed watching her indulge in her own pleasure, often encouraging her to put on a show for him. She never got tired of the way his artificial eyes watched every movement of her body and all its newly created appendages. He made her feel sensual and powerful, praising her confidence and her love of sexual experimentation. He also adored it when she turned her powers on him, holding him down with dozens of conjured hands while she rode him to completion or simply touching him teasingly with a hundred gentle fingers.

As she watched him fixate on the way she played with her own clit as he pounded into her roughly, she couldn’t imagine finding someone who was a more perfect match. He wasn’t intimidated by her, but respected her greatly. He affirmed her existence, sharing the burden of being marked a criminal simply for holding knowledge that others wanted buried. He reminded her every day with his warm smile and hearty laughter that her choice to live had been the right one, and while she was grateful to all of her nakama, Franky held a special place in her heart, a shared understanding she would never find with anyone else.

He was also right in the fact that few others would be so sexually compatible with the historian. While demur and mild-mannered in polite company, she was often insatiable in the bedroom. Between her devil fruit powers and Franky’s ability to build just about anything he could dream up, physical intimacy between them was anything but boring.

A hand pressed lightly against the cyborg’s chest, causing him to still. When he slid free of her sex, one of her hands quickly took its place, filling herself with two fingers as deep as they could go.

He could only gape as she moaned wantonly, both her breasts being fondles and her nipples pinched and pulled while she fucked herself with her own two fingers. The hand at her clit never let up rubbing the swollen pearl.

After a few moments, her fingers withdrew, the hand grasping Franky’s still buzzing cock and guiding him back inside. However, as soon as he was deeply sheathed, her arm reached around behind him to probe his backside with now wet fingers.

Franky stilled, going rigid as he felt her circle his puckered hole gently before applying steady pressure with one finger, waiting for him to relax enough to grant her entry.

This was not the first time she had explored this particular orifice and he knew what she wanted. While still balls-deep in the woman beneath him, he forced himself to relax, unclenching enough that a single finger was able to slide inside.

His head tipped back, jaw set as tried to cope with the feeling of her perfect warmth squeezing his cock, and her slender finger slowly sliding into his ass. All the while, she was spread out in an erotic display, assorted hands roving over her pale skin and making her whimper. Franky gripped her hips so hard he was afraid they might bruise but if he was causing her discomfort, she didn’t show it.

The digit in his ass was joining by a second, slowly stretching him as she pushed in deep enough to reach his prostate.

“Oh fuck,” he groaned, mouth falling open as she set up a steady rhythm, aided by her own slickness that she had collected on her fingers.

“I seem to recall you promising to fuck me extra hard,” she teased breathily, squirming underneath him in an attempt to get him to move again.

He let out a huff of amusement, focusing on her again.

“You’re being quite a distraction,” he growled, forcing himself to move again, albeit at a much slower speed.

What would have been a mirthful laugh morphed into a moan as Franky drew back and then filled her deep with a satisfying squelch, the vibrating tip of his cock pressed up against her cervix and stimulating her in a way that made her toes curl.

While his rhythm wasn’t quite so frantic, he made sure to surge into her deep and hard, rattling his workbench while Robin continued to pleasure them both with extra sets of hands.

“If you keep up what you’re doing, I won’t last very long” the cyborg warned as she tickled his prostate with the perfect amount of pressure.

“Good, because I’m close,” she panted, the fingers on her clit circling the nub even faster.

“Wait,” he groaned through gritted teeth as she clenched around him anew. “Together.”

Robin whimpered an agreement, focusing on coaxing his orgasm out of him with clever fingers while staving off her own release.

A few more thrusts and careful probing with her fingers was all it took for her lover to cry out, “Now!”

His rhythm broke as he pounded into her erratically while Robin rubbed her own clit hard and fast. The last thing she saw before her vision went white was Franky’s features contorted in pleasure. Her own release damn near knocked the wind out of her as pleasure ripped through her with an intensity that was almost violent. She was so overcome, she lost her focus on her powers and the arms around them evaporated in a spray of petals.

Even without the additional stimulation, her orgasm kept going, making her shake as she held onto the workbench above her for dear life. Though the cyborg had stopped thrusting, his cock was still vibrating at full force. The oscillations were making her sensitized body jolt and soon her moans of pleasure turned to pained whines.

Sensing her distress, he gathered enough energy to reach down and turn off the attachment, giving her some relief. She collapsed back with a final gasp, and when the rippling contractions passing through her finally diminished, she let her eyes flutter open, struggling to catch her breath.

Franky still had his hands at her hips, gripping her tightly even as he sagged against the workbench, his own orgasm hitting him with enough intensity to turn his reinforced legs to jelly.

For a moment, they both panted hard, trying to collect themselves. It was the cyborg who recovered first, releasing her so he could brace his hands by her head as he bent down to kiss her gently.

Robin sighed into his mouth, feeling utterly satisfied and completely relaxed, although the workbench’s hard surface was beginning to become uncomfortable. She kissed him softly, waiting for the feeling to return to all her limbs, enjoying his faux-lips against hers.

When he at last pulled away, he murmured, “have I told you that you are suuuper amazing?”

Robin combed her fingers affectionately through his now very disheveled hair.

“Not recently,” she said with a smile.

“Well you are,” he chuckled. “And I love you, Nico Robin.”

Although it was far from the first time he had said those words to her, her chest still fluttered warmly every time he confessed. She had lived without the love of others for so long, she had given up on ever finding it, yet here it was. She had found her match in the strangest of places. A demon and a cyborg, what an unlikely pair.

“And I love you, Cutty Flam,” she replied, using the name he hid from others, but had entrusted to her.

He went to kiss her again but noticed her wince, her spine no doubt abraded from all the friction against the hard surface of his workbench.

He picked her up and cradled her against him until she felt confident enough to unwrap her limbs from around his waist and support herself on rubbery legs. Now that she was vertical, gravity kicked in, causing the sticky remains of both of their releases to leak from her in creamy trails down her thighs.

While Franky had upgraded his genitals, he had also made the handy adjustment to stop the flow of his sperm during sex, essentially giving himself a mechanical vasectomy. It could be easily reversed by reattaching a small rubber hose within his body, but until he was ready to grace the world with little Frankys, the chance of pregnancy in his partner was zero. While sex with the cyborg was safe, it was still incredibly messy.

He handed her one of the towels he had started to keep around the workshop for just such a purpose. Besides, her next stop would be to try and sneak off to the shower anyway to clean up.

While she was trying to wipe up the worst of the mess, Franky gathered her clothes from where they had been strewn.

“I keep meaning to build us a love nest,” he chuckled as he handed them to her. “But there’s not exactly room for a bed in here.”

He walked a few steps to the mini fridge that he kept stocked with his favorite cola, grabbing a bottle and popping the cap before drinking nearly half the contents in one gulp.

“Is there an abandoned storeroom somewhere you could convert and squeeze a bed into?” she asked hopefully. As grateful as she was for this corner of the ship that offered them some privacy, she couldn’t remember the last time she had had the luxury of having sex in an actual bed.

“Nothing that would give us any privacy,” he lamented. “I swear, if I ever have to build us a new ship, I’m building you an entire suite.”

Robin giggled, rising up on her tip toes to steal a kiss from him. Even at her full height, he had to lean down so she could reach them. His arms wrapped around her, embracing her still nude form as his lips moved tenderly against hers.

Suddenly, footsteps could be heard in the hallway outside their door. They were sharp and distinct, the sound of small hoofs rather than larger feet.

“Robin,” his small voice called from outside the door.

The historian suddenly realized that when she had lost her concentration on all her extra arms mid-orgasm, she had also prematurely dispelled the eyes and ears around the ship. Because of this, the little reindeer had managed to sneak up on her.

“Yes, Chopper,” she called, keeping her voice calm despite clearly panicking a little. She quickly stepped into her underwear and shrugged her top back on, summoning hands to zip it up while she fumbled with knotting her long sarong skirt at her hip.

“Sanji is looking for you,” he replied. “Something about taste testing a new recipe? It’s also my day to shower and you promised we would bathe together later.”

Robin smoothed down her hair before shooting her lover an apologetic look as she walked to the door. Mouthing “I love you” before cracking the door open just enough to slide her body through. Franky hadn’t yet removed his attachment or pulled his briefs back on and his secret compartment full of dicks was still on display. She didn’t want to have to have the birds and the bees talk with the little reindeer, or explain the fact that some of Franky’s inventions were of the adult variety.

“Have you been down here all afternoon?” the tiny doctor asked as they began to walk towards upper deck.

“Yes,” Franky was busy working on something and I was reading while keeping him company.”

Her words weren’t a complete lie. She had been reading while the shipwright put the finishing touches on a weapons enhancement. However, once she was sure the rest of the crew wouldn’t come looking for either of them for a while, her book had been quickly forgotten.

Chopper’s steps faltered as he raised his nose in the air and gave a cautious sniff.

“Did he spill something on you? You smell weird.”

“I…” Robin stalled, features placid despite her mind scrambling for an answer. “I must have stepped in some mechanical lubricant or something. Franky’s workshop can be a little messy sometimes.”

“Hmm,” Chopper said with a nod, too innocent to think anything about her answer was strange. “It’s a good thing it’s shower day then!”

From inside his workshop, their voices were just loud enough for Franky to hear their conversion. At Robin’s lie about “lubricant,” he let out a boisterous laugh.

Although barely audible through the soundproofing, Chopper’s sensitive ears picked up the cyborg’s raucous laughter.

“He sure is weird,” the reindeer remarked. “But he is so cool too, don’t you think?”

“Yes,” Robin said as they climbed the stairs to the deck. “I certainly do.”
