Chapter 10 - The Day/Night Cycle (Verse one piece) Part 2

part 2  

Adding a Third

It had been almost two weeks since the eventful  night when Nami had discovered Momonosuke's secret, to her equal surprise and delight. Since then, the busty navigator had spent every night from sundown to sunup in his bunk, and found herself rather distracted during the day, to say nothing of physically tired and drained. Luffy didn't notice anything as usual since Nami was still able to keep them on a steady course, and Sanji only noticed her renewed appetite which had caused him to joke that his darling Nami-chan might be eating for two (she then promptly overcame her fatigue and smacked him in the head), and among the whole crew there was only one member who was curious about this new state of affairs.

Nico Robin, who was one of the most wanted women in the world and that status wasn't only due to the massive bounty on her head. In addition to her intelligence, valuable and unusual Devil Fruit power, Robin was also one of the most beautiful woman anywhere in the world. Only recently having turned thirty, Robin's face and body remained almost completely untouched by age. Her long legs were lithe and tone, and her high heeled pink shoes only further accentuated that-without them Robin was a little over six feet tall and with them, she was positively amazanion in appearance. This impression was only furthered by her flat stomach, utterly free of any fat, on display between the bottom of her tight blue jacket zipped down to show generous amounts of full, perfectly shaped breasts, and the top of her sarong, tied to show off Robin's alluringly tapered hips and mouth-watering oblique muscles.

Robin had always been aware of her sex appeal, but had never had much cause to rely on it, unlike some women she knew. Her cunning, bravery, and distinct knack for reading a situation had seen her through all her life's troubles-and there had been many of those-so far. Still, it had done wonders for her confidence, and even now, as Robin strolled leisurely around the deck of the Thousand Sunny, there was a slight bounce in her step that only highlighted her obvious assets. As impressive as Robin's enormous, fully shaped breast were, her bouncing ass, jiggling with natural bounce but with toned firmness as well was the envy of many a MILF across the entire Grand Line.

As Robin walked her dark hair, almost blue in the low evening sun, waved in a loose ponytail down the sinuous shape of her back, ending just above the small of her back. Her waist was nearly as slender as a teenager a foot shorter than her, yet her hips exploded out in an exaggerated heart shape that was positively sinful compared to the slender nature of the rest of her body, elegant arms and svelte, attractive legs. The archaelogists's aloof nature only served to height her natural sex appeal, as if her calm demeanor was challenging any would-be suitor to prove themselves worthy of her time and attention.

But tonight, her curiosity was piqued for something more than rare artifacts or lost history. While normally Robin was respectful of her crewmate's privacy, her powers let her violate it when she wished, sprouting eyes or ears on any surface she wished. And with Nami's recent, odd behavior, Robin had been tempted enough to sneak a peek at what exactly went on in Momo's cabin at night.

So Robin waited on the deck, watching the sun slowly dip beneath the horizon's edge, until the ocean only dimly reflected the night sky above. As if on cue, she heard doors open and close as she shut her eyes to concentrate and listen. Nami's door first, followed by the navigator's soft footfalls, and then Momonosuke's door, both shutting with an impact that suggested great urgency. 

Robin waited a little longer, knowing exactly she'd be walking in on. Only after ten minutes or so had passed did she descend from the ship's deck, the sound of her steps intent and assured as she moved with purpose. When the leggy brunette reached Momonsuke's door, she didn't bother to knock, pausing only to savor the moment and the looks of surprise she would no doubt encounter.

Robin opened the door quietly, but even if she had thrown it open with a sudden gasp, she doubted the cabin's occupants would have noticed right away. They were rather engrossed with what they were doing.

The scene was much as Robin might have imagined, only moreso. The sparsely decorated room was full of noise-grunting, gasping, the impact of skin on skin and the bouncing springing sounds of the mattress. Nami was facing the door with Momonosuke crouched behind her, both of them completely naked-Nami's clothes made a trail to the bed while Momonsuke's were discarded in the corner. Momonosuke held onto Nami by the forearms, gripping her tightly and pulling her back towards him as he thrust forward, his cock spearing her pussy wide open as her moans grew louder and louder. Nami's forehead shone with sweat, and her face was flushed, her tits bouncing and swinging wildly as Mono pounded her roughly from behind. 

Nami's eyes were glassy, unfocused which explained why she hadn't noticed Robin, and Momonosuke was too busy staring at Nami's ass as it smacked off of his toned pelvis. Robin took some time to admire the smooth, muscled lines of Momonosuke's body in this new form, as the young man from Wano seemed to be equal parts rampaging, lusting beast with a massive dick as well as an almost regal, elegantly handsome figure, all with the same boyish air he had in the daylight.

"Enjoying ourselves, are we?" Robin asked, clearing her throat before speaking in an almost delicate manner, as though she were embarrassed to interrupt.

"Ah...wuh, Robin?!" Nami said, seeming to come out of the dick drunk haze she was in, even as her body cried out in ecstasy at every motion Momonosuke's dick made inside her tight, wet pussy, impaling her all the way into her womb-indeed Robin noticed a little bulge in Nami's midsection every time the hung stud thrust particularly deep inside her.

For his part, Momonosuke was just as surprised by Robin's appearance but managed to hide it better than Nami.

"Oh, Robin, hello...I almost didn't see you there." He grunted as Nami rocked back against him, the slick walls of her pussy squeezing his dick with impressive force, as though trying to milk him from the inside. Momonosuke favored Robin with a cocky grin, and she had to admit the look suited him well-rutting into Nami from behind like that, making the buxom young woman moan and pant like a bitch in heat, he certainly seemed like a triumphant prince enjoying his rightful spoils.

"Yes, you seem rather occupied. But, if you're not too busy…" Robin said, crossing her arms as she leaned against the door frame. She slowly kicked it shut behind her with one foot, her demeanor oddly casual as she took the scene in, her eyes flickering over every inch of Momonosuke's body, and Nami's as well, while the orange-haired girl simply moaned. Her body shook as Nami's slender hands gripped the sheets, clearly having a teeth-clenching orgasm as Momo thrust particularly deep inside her, his column of dick churning her insides up in an almost painfully delightful way.

"Well then perhaps I could interest you in trying to have some fun with a real, mature woman. I can promise you I'm more of a match for you than poor Nami there."

"Ah...screw you, Robin…" Nami replied, but even stringing that sentence together and trying to focus on anything other than the fact she was getting the absolute shit fucked out of her tight pussy was an enormous effort for her.

Smack!

"Don't be rude now, Nami. Let's see if Robin can actually back up her words. Sure, you have an absolutely amazing body Robin, but do you really think you could handle me?" Momo pulled back until only the tip of his dick remained in Nami's pussy, pushing her down by the small of her back lightly, so as to give Robin an unimpeded view of the sheer length of his weighty dickshaft.

"Allow me to demonstrate." Robin replied, as unflappable as ever. She reached one slender hand into the tied front of her sarong, retrieving a small metal cylinder from inside, an object that glinted in the light and that Momo soon recognized as a spyglass.

Momonosuke cocked an eyebrow at the tall woman in curiosity, even as he continued railing into Nami's pussy, the speed and strength of each thrust ramping up to an even more intense level. Nami gasped and moaned, trying to think of something to say to get Momonosuke to forget about Robin, but at that point it was hard enough for her to remember her own name. Drool leaked from the corners of her mouth as her eyes crossed, having another orgasm strong enough to make her heart skip several beats. Her pussy gushed and juices splattered the bed beneath the roughly mating pair as Nami fell forward, propped up on her forearms.

Momonosuke watched, clearly intrigued even as he tried to ignore the waves of pleasure washing over his dick as Nami's orgasming pussy clenched around him like a hot, slick vise. Standing a few feet from the bed, Robin raised the spyglass, flicking it with one sharp motion and causing it to extend to its full size, sliding out into three sections of gradually increasing thickness. Robin smirked openly, every bit the performer about to show off, as she opened her mouth wide. 

With almost tortuous slowness, Robin's lips stretched around the spyglass, suckling the cold metal in her warm, moist mouth. She swallowed the first section in a single movement, tilting her head backwards until she was looking nearly straight at the ceiling. The second section dipped past her open mouth, and her jaw stretched wider a bit as a hint of a bulge started to appear. With a quiet gulping sound, nearly the entire thing disappeared into Robin's mouth, her neck bulging as she made a few exaggerated swallowing motions. She brought one slender hand up, massaging the clear bulge in her swan-like neck as her other hand held on to the very tip of the seeing device. 

As Momonosuke watched, he slammed his hips forward, burying his cock deep inside Nami's dripping cunt, hitting the back of her womb. As Nami convulsed beneath him, Momonsuke's balls clenched, his dick stiffening as he began to come. His eyes were on Robin's neck and her slowly rising, heaving chest as he sawed his dick in and out of Nami's gaping pussy, shooting over a dozen massive, hot sticky loads of jizz right into her unprotected baby bag.

With a gasp, Momonuske pulled back, while Nami lay sprawled on the bed, her eyes forming comical swirls, completely incoherent in that moment. Robin slowly pulled the spyglass out of her mouth, letting a delicate, cloudy strand of spittle connect the end of it to her plump lips. She snapped the object closed again, putting it back in her jacket as she lowered her head to face Momonosuke again, looking very pleased with herself in a quiet sort of way. 

"Well?" Robin asked, wiping spit away with one delicate finger.

"Surely you see that it's time you take on a real woman, someone a bit more mature than Nami. One who measures up to you." Robin cooly cupped her breasts as she spoke, pushing the massive, perfect jugs up high on her chest, till they were in danger of hitting her chin.

Momonosuke smiled broadly. Robin's attitude reminded him of how cheeky and confident Nami had been that first night. While he had to admit Robin had the body to back it up, her tits and ass even bigger than Nami's and her mouth-watering legs seemed to stretch on forever, the prince from Wano was certain Robin would be begging and pleading for his dick before too long just like Nami had.

"I think you're right Robin. But don't be surprised if you end up like Nami here." He smacked the former cat burglar's thick ass as he pulled out of her pussy, leaving her gaping. Nami collapsed onto the bed, mewling in the aftershocks of her orgasm, only dimly aware of what was going on. 

As Momonsuke moved to sit on the edge of the bed, his dick still completely hard, Robin just smiled in response, taking his remark in stride. She took a deep breath and then exhaled, her breasts seeming to swell up. There was a brief moment of strain from her jacket as the material struggled to hold back Robin's titanic tits, and then with a sudden inexorable momentum, her zipper began to come undone, peeling down to the bottom before her jacket fell open.

Zi-iiiiip!

Momonsuke simply stared like a kid in a candy store as Robin's full, perfect breasts were on display for him, huge mounds that pushed up against each other, forming a tight line of cleavage even as they hung out far enough to be seen from behind Robin's thin back. They seemed even more preposterously large above her taut stomach and the tiny shape of her waist. Robin shrugged her shoulders out of the jacket, letting it fall to the floor as she seductively stalked closer to Momonosuke.

Robin got on her knees slowly, taking her time and enjoying herself, her eyes locked onto Momonosuke's. For once, the pervy, cocksure young man had nothing to say, showing sheer respect for Robin's bombshell body as well as something almost like awe. Now he knew what it was like when a girl saw his huge dick for the first time, a role reversal he hadn't quite expected. He watched as Robin slowly reached out and began to stroke his cock, working both hands in firm, measured corkscrew motions, up and down.

Robin could barely get her fingers halfway around Momonsuke's fat, steel-hard cock but she knew exactly what to do with such a beast. As she jerked his dick with almost intense focus, her mouth slowly opened as wide as a snake trying to swallow a massive egg, her cheeks flushing slightly. The scent of Momonosuke's cock and his huge, swarthy balls was seeping into Robin's head, making her body tingle with lust, though outwardly she maintained an almost serene demeanor. 

Robin inhaled Momonosuke's cock, her cheeks hollowed out and her lips wrapped tight around his shaft. Her soft, wet tongue pressed firmly against the musky underside of his cock, feeling the powerful veins throb as his dick filled more and more of her mouth. While Robin had never sucked (or even seen) a cock so large, she did her best to handle it with something like practiced ease. Momonosuke moaned above her, his legs going slightly stiff as Robin's hands dipped down, fondling his massive balls, feeling their weight and heat. Robin let out a light moan at the feel of them in her hands, each one large enough for her to palm, almost impossibly massive and no doubt stuffed with veritable gallons of hot, potent sperm. 

Robin bobbed up and down on nearly half of Momonosuke's huge cock, leaving it glistening wet with spit. She alternated these long, languid sucks with popping the flared cockhead out of her mouth and licking with eagerness at the base of Momonosuke's cock, inhaling deeply at the scent of his virile balls, before dragging her tongue back up to the tip of his cock, the darting pink appendage licking along his wide piss-slit. The busty woman made sure to keep her eyes on Momonosuke's face at nearly all times, enjoying how clearly he was impressed with her efforts. Despite her resilient exterior Robin's eyes soon fluttered and the color in her cheeks darkened, clearly enjoying herself yet very much in control of that situation.

Momonosuke knew he had to do something about that. At this rate, he'd end up wrapped around Robin's finger; if he wanted to exert dominance he had to act now. He reached down, wrapping his hands in her soft, luxurious hair in a firm but not rough grip. Robin's gaze didn't waver, though she clearly knew what was coming-if anything, there was a sudden twinkle in her eye, as though she was egging Momonosuke on.

Do it, her face seemed to say. Show me what you can do.

Momonsuke's hips pushed forward, even as he pulled Robin's head towards him, dragging her head as his cock drove deep down her throat. Inch after inch of that massive cock disappeared into Robin's gullet, and soon a large, mushroom shaped bulge appeared in Robin's neck, soon hitting the exact spot that had marked the terminus of the spyglass' descent earlier. With a grunt as Momonosuke sat up a bit straighter, his leg muscles tensed, there was a bit of resistance before Momonosuke's dick pushed forward. Robin gurgled, her eyes watering as her hands landed on Momonosuke's sweaty thighs, gripping him firmly, not to try to push him back or halt his advance into her tight throat, but simply to anchor herself in place further. It was obvious that Robin was quite sure that whatever Momonosuke could dish out, she could take-and in fact she was eager in her own way to get her face well and truly fucked.

"Gllch, glchh, glagggk!" 

Despite her resolve, Robin's throat was simply unused to handling a cock so big pumping into her throat at such an intense speed, and her eyes seemed to bulge slightly as she retched. Even as her face grew red, her eyes showed no trace of concern or worry, though there did seem to be a small hint of being impressed by Momonosuke's impudence and lusty bravado. Robin's thighs rubbed together as Momonosuke fucked her throat roughly, burying nearly all of his cock inside her throat over and over again, churning her up and making bubbles of cloudy spittle froth up at the corners of her mouth.

Momonuske tilted his head back, getting lost in the sheer bliss of pillaging Robin's throat, hearing her gags and small, quietly lustful moans fill the room. With a sudden shuddering push, Momonosuke's cock disappeared entirely inside Robin's tight throat, forming a bulge that extended the entire length of her neck and continued on, almost visible between her massive tits. Robin's eyes crossed, just for a moment as her nipples grew almost painfully hard. Her panties grew suddenly wet as Robin came, having a hands free orgasm simply from getting her skull fucked by Momo's giant cock.

What a...beast! He's fucking my throat just like a pussy, using my mouth to get off. Momonosuke is really something else-he made me come just from sucking on his cock, like some cheap bimbo! 

Robin looked up at him, even as Momonosuke slowly withdrew his cock from deep within her throat-at that last moment, when he'd thrust so deep, it even felt like he'd hit the bottom of Robin's stomach. Her eyes had leaked a few tears down her flushed cheeks, leaving little tracks in their wake, but Robin did her best to keep her gaze strong, resolve dented but intact. Momonosuke acted much as she expected, like many young brash men who thought they were god's greatest gift to women, Robin had encountered many like that. The only difference was that the young prince of Wano had an endowment and seemingly boundless stamina that implied he could actually live up to that.

Momonosuke smirked down at Robin, whose face had already returned to a quietly flirtatious sort of serenity. He was so focused on her, and she on him that neither of them noticed Nami watching the action unfold between them with rapt attention, still a little out of it and content to just watch.

"Why don't you show me what you can do with those fat tits of yours, Robin?" He asked, taking on a somewhat challenging tone. After a fairly brutal throatfuck that would have left most women retching and blue in the face, Robin just looked like she'd been exerting herself for a few moments like jogging at a brisk pace. It was clear he'd need to do more to exert any sort of dominance, but for now Momonosuke was happy to just enjoy Robin's sinfully sensual body.

"You young men are always so obsessed with a pair of big, fat breasts, aren't you, Momo~?" Robin replied, shimmying forward on her knees. Her delicate hands squeezed her breasts from either side, wrapping them around Momonosuke's titanic cockshaft and suqeezing him in a slick, tight embrace. As he watched, enraptured, Robin began to bounce in place, lifting and heaving her perfect jugs up and down around his cock. While clearly doing her best to please him, it was also obvious that none of this was particularly difficult for Robin. Indeed, her work with such a huge dick made Nami look like a rank amateur.

Robin's grip was tight enough to leave little dimples on the skin of her breasts, indentation marks from her perfectly trimmed fingernails as she applied just the right amount of pressure. She worked Momonosuke's dick like an experienced professional, wanking his dick off with alternating speeds, first going fast and wild, making her tits blur, and then using slow, smooth strokes to really squeeze his shaft. She wobbled her breasts from side to side, making sure to cover every inch of Momonosuke's dick, her eyes never budging from his face. As the minutes ticked away, Momonosuke's pleasure grew and grew, sweat trickling down his brow until it was simply too much for him to bear.

"Ah...fuck Robin, that feels so good. I'm...I'm gonna come!" For a moment his own arrogant attitude vanished, washed away by the sheer tidal waves of ecstasy he was feeling. His dick stiffened in between Robin's breasts, and Momonosuke's fat, wrinkled balls grew tight as his orgasm overtook him. 

Spllrt! Spllrt! Spllrch!

With heavy, thick gouts, Mono's cock erupted all over Robin's thick breasts glowing with sweat, covering them in a gooey, hot lattice of spunk. Robin let out a soft moan at the sensation of receiving such a massive load, working her tits faster against Momonosuke's cock as he thrust into the valley of her cleavage. She could practically hear his balls churning out more and more of the potent seed, and soon even her massive breasts were completely covered in the potent, off-white seed.

When several minutes had passed and Momonosuke was finally finished, his dick reamined as hard as ever, standing tall and casting Robin's face into shadow. She smiled at him sweetly, like a mother impressed with a son's hard work and earnest efforts.

"Ah, what a thick load you made, Momonosuke, all that virile sperm, all for me." Robin opened her mouth slowly, theatrically, moving her hands to gather the jizz that covered her tits and scooping it into her mouth. She made exaggerated, flirtatious moans and gasps as she practically chewed the tacky stuff, gulping it down slowly, letting Momo enjoy the show she was putting on. Privately, Robin's tongue burned with the taste of that pungent, though not unpleasant ball batter, letting it pile up in her mouth before swallowing it down heartily, coating her mouth like a nasty film.

"Mmmph…" She smacked her full lips together, nasty strands of spunk stretching like a spiderweb before her open mouth, globs of it stuck between her teeth.

"It's just too bad you young men always come so fast. I would have enjoyed sucking on your fat cock a little more, I must admit." Robin winked at Momonosuke, and he felt a vein go taut in his forehead. If she wanted to keep playing this game like she wasn't totally swooning for his cock, then he'd have to show her that it was a game she was certain to lose. 

"You're quite a catch Robin, as I'm sure Nami would agree." 

Nearby Nami was openly masturabating, sitting on the floor of the cabin and enjoying getting an eyeful of both Robin's magnificent body and Momonosuke's fat slab of cock.

"Now, why don't you get up on the bed, Robin? On your hands and knees like a sexy little bitch." If Momonosuke expected Robin to rise to the slight insult, he was to be disappointed. Instead she simply climbed onto the bed, slowly tugging her sarong down as she did so, exposing the rest of her wide hips beneath her impossibly slender waist. Robin only wore a thin pair of black panties underneath, and she took great joy in tugging them down, shimmying her body this way and that. 

As she knelt on the bed on all fours, the view from behind her was impossibly sinful, her body goddess-like in its feminine beauty. Momo's speed betrayed his eagerness as he clambered onto the bed behind her, his eyes taking in the two wide globes of Robin's ass, unable to keep himself from reaching out and palming them. While his hands were by no means small, they certainly weren't large enough to contain all the fat ass that Robin was packing on her otherwise svelte frame.

Robin looked back at Momonosuke over her shoulder, dark strands of hair draped down her slender neck like elegant curtains. She smiled at him playfully, wiggling her hips slowly in an almost mesmeric fashion, the fat yet firm ass wobbling slightly.

"Well, are you just going to stand there and stare all down, Momonosuke? I haven't really got all night you know, and I-ahh, mmmm!~"

Wham!

For once Robin was truly caught off guard as Momonosuke thrust his hips forward, his cock spearing into her tight pussy with bone-shuddering force. Robin felt every inch of Momonosuke's cock buried deep inside her pussy, stretching her open like nothing she'd ever felt before. His cock was so thick, Robin felt like someone had reached in and grabbed the sides of her pussy and forcibly opened it, leaving her gaping, and Momonosuke's dick was so long she felt his cockhead punch up against her tight, sensitive cervix. 

"Ah...so deep." Robin muttered to herself, before squealing as Momonosuke pushed his hips the last few inches and sunk to the balls deep inside of her, his dick bottoming out inside her womb. Her body convulsed a bit as Robin suddenly came, her orgasm hitting her with a harsh abruptness. Her tight, slick inner walls gripped Momonosuke's dick forcibly, and he had to push with great force to saw his dick back and forth inside her dripping cunt. She'd been penetrated so quickly and so hard, that it had sent her into an overload of pleasure.

"Fuck, you're so tight!" Momonosuke gasped, holding onto Robin's slender waist with one hand. With the other, he smacked her fat rump, sending the thick ass to wobbling as he repeated the action over and over again. 

Smack! Smack! Smack!

"Ahh! You cheeky little boy~" Robin said, even as she rocked back on her elbows, wiggling her hips as her body seemed to come alive in a way it never had before. The feelings stirring up in her heart were nearly as intense and wild as how deeply Momonosuke's cock was churning the inside of her pussy up-already she was so wet that it almost felt like she was practically frothing around Momonosuke's dick. Sweat trickled down her forehead, even as her nipples grew hard and her legs started to shake.

"Not...bad, Momo." Robin managed to sound composed, even as he pounded away deep inside her, not letting her get used to his size or pace. Instead he thrust faster and faster, alternating between long hard thrusts and a series of fast, harsh pumps, his flat and well muscled pelvis smacking off of Robin's thick, heart-shaped ass.

Wham! Wham! Wham!

The bed seemed to rock as though the ship's cabin was in the middle of a massive seastorm, rocking back and forth. Robin dimly noticed that Nami had found a Den Den Mushi of some sort, and was apparently capturing her rapid, harsh fucking for posterity. She thought of saying something, but found it hard to focus on anything but keeping her composure, even as cracks began to form in her facade. She was a bit glad Momo was fucking her from behind so she could hide her more embarrassing, ectasic expressions.

"That's right Momonosuke, show her what you can really do. I bet she'll be screaming your name in minutes." Nami said, practically salivating at the thought.

Momonosuke didn't need to be told twice, and he proceeded to fuck Robin's pussy rotten for the next half an hour. She came on his cock over and over again, and her face was soon sweaty and very flushed, her hair a mess dangling in front of her face. Her fat ass was covered in handprints, and the bed between the pair of them was covered in stains and dark spots from her leaking juices, and both Robin and Momonosuke's bodies were covered in sweat.

Robin looked over her shoulder, managing to look fairly composed, even though internally she was rapidly losing her defenses. She'd never come so much in such a short span, and Momonosuke still seemed to be going strong.

Her voice shook with the sheer impact of Momonosuke's thrusts, but she sounded almost normal, if out of breath. 

"Well, Momonosuke you sure seem to be putting a lot of effort into this. Are you sure you don't need to take a break, little boy?~" She smirked at him, looking rather pleased with herself, even if a lot of that was from the constant aftershocks of orgasms running through her before her body was rocked again by new ones, like a series of thunder strikes.

Momosnouke paused for a second, wiping the sweat away from his brow with the back of his hand. For just a moment, it looked like he was going to stop and perhaps catch his breath. Instead, his arms snaked forward, looping underneath Robin's armpits. He suddenly stood up, taking her with him and bodily hoisting her off the bed.

"Ah...so strong~" Robin breathed, her head spinning as she tried to adjust to this new position-standing up, Momonouske's cock was lodged deep inside her pussy at a different and highly pleasurable angle. Momonosuke's hands moved around and clasped together at the back of Robin's neck, locked inside her knees holding her firmly in place-the busty woman felt like she'd been practically impaled on his cock as though it were a stake.

Wham! Wham! Wham!

At this new angle, Momonosuke showed her even less mercy than before, ramming upwards, deep inside her pussy over and over again. Though Robin was slightly taller than Momo, in this new position she looked rather small indeed, with her body bent in half. Her legs shook wildly as her pussy was plundered, her high heels actually flying off. Toes curling in ecstasy, Robin's teeth were grit, trying her best simply to stay sane.

"Oh my god...fuck, Momonosuke your cock is so fucking big!" At this point, Robin simply couldn't resist singing Momo's praises, his dick was so huge and it felt so fucking good. His balls were slapping off her clit as he thrust into her faster and faster, grunting deeply in Robin's ear. His cock seemed to get even harder inside her, growing stiff.

"Take it, Robin, take it all!" Momonsuke hilted his cock inside Robin's pussy once more, holding her tightly in place. Their bodies ground together as Momonsuke came again, an even larger load than before.

Spllrt! Spllrt! Spllrt!

"Holy fucking shit~" Robin said, her body and mind nearly overwhelmed by sensation. The thought of Momonosuke coming deep inside her unprotected womb, possibly getting her knocked up like a common whore. She could feel her body filling up, and soon jizz squirted out past the tight seal her pussy had formed around Momonosuke's cock, even as Robin herself came, her own juices added to the hot sticky mess that hit the floor. The room soon stank of sex as Nami kept recording the sordid events, with Robin's eyes briefly rolling up in her head.

Knowing that he had as strong of an advantage now that he'd ever had, Momonosuke decided to seize the moment. As Robin struggled to get her breathing and heart rate back to normal, he pulled his cock out, still hard as stone. His bell-end slapped hard against Robin's pussy, and she shuddered in his gasp, nearly coming herself stupid all over again.

As Robin's mind whirled, she could barely hear Momo and Nami discussing something. Her long, butterfly eyelashes fluttered for a moment, leaving her seeing the events in stuttered flashes. The next thing she heard Momo say was a mocking challenge as she wobbled on her feet, before sitting heavily on the bed.

"Well, had enough yet, Robin? Do you give up now, I'll take it easy on you if you do, maybe go a few rounds with Nami before I get back to you."

Robin huffed and puffed for a second, before taking a single long deep breath. While Robin's Devil Fruit powers were usually limited to sprouting extra limbs, they had the secondary effect of making her quite resilient-on a very small level, her body could sprout duplicate cells for rapid healing, helping her re-oxygenate her blood, and much more. Not an expert in biology, despite her natural intelligence, Robin didn't quite understand it herself, but at the moment it gave her a leg up that most people simply wouldn't have.

"Oh, I'm good to go a little longer if you are, Momo-chan" Robin actually had the gall to wink at Momonosuke, her expression making it clear she wasn't ready to submit yet. Her second wind seemed almost miraculous, but Momonosuke wasn't deterred.

"Nami, do you have what I asked for?" He said, sounding almost sweet, like a patron at a restaurant asking for a rare dish.

Nami returned from where she'd been-Momonosuke's rather large cabin closet, Robin surprised, holding what looked like a length of rope, though oddly colored. Momonosuke took it from her almost gingerly, before turning to Robin with a smile on his face.

"Oh, is that the sort of thing you're into, Momonosuke? Well, go on, do your worst, though I'm afraid being tied up is a little vanilla for me." Robin said, sticking her hands out willingly, wrists together and palms up.

"Ah, I think I can still surprise you, Robin. You see, I think you know what this is, though you've probably never seen it before like this. It's actually quite common where I come from." Momo retorted, and as he advanced on Robin, her eyes finally recognized what she was looking at. The rope Momonosuke was holding wasn't just any rope, it glinted with a dangerously familiar light.

Seastone. The rope was laced with Seastone, which Robin suddenly remembered actually came from Wano country, Momonosuke's birthplace. If he tied her up with that, she'd be….

"Helpless." Robin said, in a voice that was now rather quiet. And just then, Momonosuke pounced on her.

In moments, Robin was bound firmly, almost like a trussed hog, with her shoulders pulled back almost painfully tight, wrists bound together behind her back. Her legs were also roped together at the ankles, tied behind her ears. It was a humiliating, completely vulnerable position that Robin had never been in before. She'd been tied up more than a few times in her sexual past, but now Robin was actually feeling a bit of fear-before she'd always had an out, as normal cuffs and bonds couldn't hold her if she didn't want them to, not when she could sprout an extra set of hands and undo them from the outside. Now, she had no recourse: she would be untied when Momonosuke decided and not a second before.

She looked up at him with eyes that were resilient, but like ice, Robin's strength was more fragile than it seemed. Momonsuke smiled down at her, impossibly smug as he rubbed his turgid cock against her pussy-which to Robin's further shame, was openly dripping, her body as turned on by this helpless situation as she'd ever been in her life. With a sudden thrust, Momo penetrated her again, but not before he'd dipped his dick down, pointing it at her tight, unprotected asshole.

"Ooo-wahhh!!" Robin's eyes rolled back in her head, showing nothing but blank whites as Momonsuke's cock tunneled deep into her asshole. He groaned at the tightness, as Robin had never had anything larger than a single finger in her ass before. Tears leaked down Robin's face as Momo pounded deep inside her asshole, and it felt like he was rearranging her body from the inside.

WHAM! WHAM! WHAM!

"Oh...gawddd!" Robin's tongue stuck out between her teeth as her pussy violently squirted, splashing all over Momonosuke as her body experienced an almost brutal double orgasm, seeming to burn through all of her nerve endings at once, pussy and ass both exploding with pleasure.

Momo grunted above her like some great beast, rutting into her tight asshole rougher than he'd fucked her before. He was holding nothing back now, pillaging Robin's asshole and taking it like it was nothing more than some prize he'd conquered. His eager, grasping hands grabbed hold of her huge tits, which bounced and shook in a blur from the roughness of his anal assualt. Momo licked and sucked at Robin's sensitive chest, his fingers roaming all over her impossibly soft, large breasts. 

It was all too much for her, and like Nami before her, Robin broke, her body and mind surrendering fully.  As she had started out so much stronger and sure of herself than Nami, so too did Robin end up even more lewd and debased than the orange haired girl, falling to a depth of depravity she never would have thought herself capable of.

"Ahhh fuck, I'm fucking coming! Shitting fuck, Momonosuke, you're tearing my asshole apart! Please, don't stop, don't stop, don't stop! Fuck me like a cheap little whore, gouge my fucking guts with your fat fucking dick!❤️️ I love your cock!!❤️️"

Robin's face was contorted in an unspeakably lewd expression, drool leaking down her chin as her cheeks burned deep red. She was babbling now, unable to form a coherent sentence as Momonsuke kept rutting into her. His hands played with her tits and ass he wished, knowing that Robin was now and forever more his sexual plaything to use however he wished.

Momonosuke kept fucking her throughout nearly the entire night, alternating between her pussy and ass. By the time he left her, passed out and insensate, to fuck Nami some more, Robin had taken another two loads each in her pussy and ass. Great gouts of jizz sloped out of her gaping holes as she was stuffed to the max, looking like nothing more than the fuckdoll she was. Her belly was expanded as though she were eight months pregnant, swollen with liters of sperm as bright pink hearts danced in her eyes, shortly before she passed out.

As morning came, just an hour before Momonosuke was due to transform back, he laid flat on his back, head propped up on a pillow. His fingers were laced behind his head, and his eyes were half closed. Below him Nami and Robin were naked, stacking their tits on top of each other as they gave Momo a lewd, sweaty, slutty double titjob. 

As he grunted, balls tight as he came again over both women's chest and faces, they stuck their tongues out happily. Each drop of his sperm in their mouths was eagerly gulped down, as though the two of them were drinking the sweetest wine they'd ever tasted. As they spoke, it was with one voice, each having the same single, overriding thought in their heads.

"Ah...thank you, ❤️️Master Momonosuke!❤️️"

Above them, the young prince of Wano smiled broadly, allowing his eyes to fall closed as he focused on the physical sensations flooding through his body. It had been a very good night, and he was looking forward to countless more to come. 

The End...
