Let Her Have Cake (Robin x Vivi & Dorthy)

A story commemorating the official birthday of Nico Robin. When the Straw Hats come across an island in the New World, Robin meets someone with an unexpected surprise.

-----------------------------------------------------------------------------------------------------------------------------------

On a world primarily occupied by water, upon one of the six immense oceans that made up its surface, the one in particular known to the world's denizens as the 'New World', a relatively small wooden ship cut through the currents, a lionhead-shaped figurehead leading its charge. On the ship's deck, a motley group of seemingly random people, some of whom the term 'people' fit somewhat loosely, was collected into a pirate crew, determined to navigate the immense body of water to its end. Among that crew was a raven-haired woman who stood by the ship's railing, staring out into the distance.

Nico Robin looked out into the waters of the New World from her perch by the Thousand Sunny's rail as she allowed her thoughts to wander. It was her birthday that day, though she had preferred not informing her fellow crewmembers of that, preferring to use the day to reflect on her life and everyone she had to thank for that life having lasted as long as it had. The scholars of Ohara, her mother, Jaguar D. Saul, Aokiji, and, much more recently, the Straw Hat Pirates, all received recognition within her as she replayed their roles in her life as she thanked them from the bottom of her heart.

Of course, there was one other person, more recent than those of her childhood, and slightly less so than the Straw Hats, that Robin often thought back on fondly: Princess Nefertari Vivi of the Alabasta Kingdom, whom the historian had met during her time under the employ of Crocodile. After giving the princess a Devil Fruit that she had come across on her travels almost on a whim, she and Vivi had combined forces, and later combined that with the Straw Hat Pirates, to put an end to Crocodile's plan to take over Alabasta. Of course, that quick synopsis of the two women's time together left out the love and lust that brought them together far more closely than either of them could have ever imagined.

Robin sighed as the many, many loving and toe-curlingly sexual moments she shared with the young princess flooded back to her. The historian knew that she couldn't complain; the Straw Hats had become the family she never truly had, and she and Nami often tended to each other's more lusty desires. Still, visions of her turquoise-haired milk goddess danced through Robin's head throughout many a night, leading to an inevitable surge of loneliness as she realized that the princess was nowhere near her, with that unlikely to change anytime soon.

On an island some distance away, a dense, but surprisingly normal forest spread across most of the land available on it. In one of the handful of clearings available within the wooded area, a cloud of pink energy began to swirl into being, growing to the size of a person before growing thicker and more opaque. After a couple moments, a glowing energy dissipated, leaving a human woman in flowing black robes and a matching wide-brimmed, pointy hat standing in its place. The newly arrived figure's gaze cast about at her new surroundings curiously, almost seeming as though she were seeing beyond the thick barrier of trees surrounding her, as she appeared to attempt to get a sense of where she was.

"Hmmm... interesting setting; what magic is around here is a bit odd, but there's quite a bit of it... slightly different physics... ooh, and what's that over there?" Rambled the being as she glanced around, her last exclamation punctuated by her gaze jerking to the south. After a few moments of examining whatever she saw through the trees that would've blocked the vision of any normal eyes, an excited grin spread across her face.

"Ooh, I have a feeling this is going to be fun..."

Robin's wandering mind was interrupted by an island appearing over the horizon, and the ensuing commotion that the discovery caused on the ship. The more immature members like Luffy, Usopp, and Brook danced about the deck, singing out their happiness at a new place to explore, and one lacking an ominous look to it, despite being in the New World, at that. Nami, Sanji, Franky, and Chopper scrambled to take inventory of the ship, doing their best to determine what they might need at the moment, and thus what the crew should try to keep an eye out for when exploring their unexpected next destination. Robin simply watched both groups, as well as occasionally taking a glance over at Zoro, who had yet to wake up from a midday nap.

The activity helped make the time pass quickly, and the island rapidly filled the view from the front of the ship, which soon brought the entire crew together to assist in getting the ship shorebound and secured. With the task quickly completed, the crew split up to explore as much of the island as they could, leaving Zoro behind to keep watch over the ship. Robin set out alongside Luffy, Chopper, and Usopp, feeling oddly giddy about the prospect of exploring this island, something that was usually reserved for her current companions.

As the pirate quartet wandered through the forest that seemed to take up much of the island, they looked around at all of the foliage the area had to offer. The plants didn't invoke much interest in the group, save an occasional plant which Chopper briefly examined before taking a sample to place in his backpack for later study. It wasn't until they came across a patch of odd-looking yellow flowers populated by a swarm of equally unusual Hercules Beetles that the three usually childlike pirates had their attentions captured.

Of course, Robin recognized that their attentions would be caught for some time by a sight like that, and so considered heading off on her own for a short while. For some reason, one direction in particular was calling out to her, and it seemed like the current situation was a perfect excuse to check it out. Leaving Luffy, Chopper, and Usopp to their fun, Robin set off.

With her powers, the dense forest wasn't difficult to traverse, and Robin found herself covering ground quickly. Though she wasn't quite sure where she was going, the piratess seemed to almost be guided through the trees, headed straight toward a singular direction. Before long, the trees before her gave way to a large clearing.

The grassy area Robin found herself in was quite wide, almost big enough to fit a decent-sized house, but the more noticeable feature was the woman standing in it. A flowing black robe was wrapped around her body, clinging to her curves, which were fairly impressive, comparable to Robin's own. Chocolate brown hair flowed from her head to mid back, a thick lock dangling over her right green eye in the process, and a black wide-brimmed, pointy hat was perched on her head. Stranger than that, though, the woman appeared to have been gazing in Robin's direction for some time, as if aware that she was coming even before the historian had gotten the idea to go that way.

"Ah, there you are. Welcome!" The woman greeted Robin, arms spread wide in a friendly gesture. "I was worried for a bit that you wouldn't accept my invitation; you seemed like the cautious type, after all." Those couple sentences already set the historian's mind to racing, wondering who the woman before her was and what she wanted.

"Who are you?" Robin finally asked, for some reason more curious than truly concerned.

"My name is Dorothy." The woman replied. "Admittedly, I'm not from around here. I came from another world to explore some different ones, to see if I could find anything worth checking out."

"So, why the apparent interest in me?" Robin continued.

"Well, of course, you're a very lovely woman; plus, it's your birthday, isn't it?" Dorothy chuckled a bit at Robin's surprised expression, but continued, "Well, I can sense these things, before you ask. I also noticed that you're feeling a bit of loneliness, which I thought I could help with."

"I appreciate the offer," Robin replied, "but I have several good friends now, and I barely even know anything about you." However, the witch-garbed woman responded to the historian by lightly chuckling.

"Oh, sorry, you misunderstand. While I can't say I hadn't thought about spending some quality time with you myself, I didn't mean me." Dorothy went on, "I was talking about a certain princess you know." Robin's eyes shot open wide as the odd woman's meaning was instantly clear, even as several new questions rose up from it.

"How do you- Why would you – How would you even get her here? Vivi's kingdom is weeks away now!" Robin finally worked out in her confusion.

"Well," Dorothy started, "I'm just guessing at your other two questions, but I know about Vivi because I can sense the connection you have with her; it's like a trail that lets me see right to where she is now. I'm not sure what equivalent you might have here, but I am what my world knows as a 'witch', so I have various magical abilities at my disposal, including the ability to teleport that princess of yours straight here. As for why, well, I can't really turn down an opportunity to reunite a pair of lovely ladies like you two, who quite clearly love each other."

Before Robin could respond in any way, the woman thrust out her hand towards a spot to Robin's left, where a cloud of pink energy soon began to swirl into existence. As Robin watched curiously, the light grew denser and more opaque, completely obscuring its contents. After a few moments more, the pink haze started becoming transparent again, revealing a feminine figure inside, the sight bringing Robin to gasp in recognition.

Sure enough, as the energy faded, more and more of the female form's features came into view. First was the waist-length turquoise hair, which flowed down from the figures head in waves. Also notable was the mostly petite figure that still managed to carry some impressive curves, especially in her large, heavy looking bust, those curves wrapped up by a dark blue bikini. Finally came the woman's face, a visage that somehow combined regal with approachable, one that spoke of both great responsibility and great kindness.

"Woah!" Vivi suddenly exclaimed as she began casting about at her new, completely unexpected surroundings; however, her violet eyes went from panicked to ecstatic as they fell upon the raven-haired historian.

"Robin!" The princess shouted in joy, running over to wrap her arms around the piratess in a deep hug at the sight of her lover. "Oh, it's so wonderful to see you again! Though... what am I doing here?" After several moments of letting mutual love flow between their entangled bodies, Vivi backed away enough to look into Robin's eyes, letting them gaze back into her own questioning ones.

"I'm not sure how, but it was the doing of that woman over there." Robin answered, tilting her head in Dorothy's direction by way of clarification. Vivi turned to look in the pointed-out direction, nodding slightly in understanding.

"I see..." Vivi said, a question coming to her mind that she was hesitant to ask, considering how happy the unexpected occasion was.

"You don't need to worry about getting back." Dorothy cut in, apparently guessing the princess's concern. "I'll return you to your kingdom as soon as you two are done having fun. It'll be like you never left there."

"Well, I was just sunbathing anyway," Vivi responded thoughtfully, gesturing at her bikini-clad form, "so I guess I'm satisfied with that." Pleased that she had quelled the concerns of the two lovers before her, Dorothy grinned, until she let out a gasp of surprise as her chest seemed to almost leap forwards as the princess showed off her only scantily concealed breasts, her robes bulging oddly where they were stretched over the ends of her breasts.

"Oh my!" Dorothy laughed at the unexpected occurance. "Vivi my dear, you have quite a supply of milk hidden in those breasts of yours, don't you?" The princess's eyes widened slightly in surprise at the woman before her somehow recognizing her Devil Fruit power without her even having done anything with it yet.

"Yes, a neverending supply of it, actually." Vivi chirped, deciding to go along with the oddity as she thrust her chest out in emphasis. Robin grinned slightly at the princess, recognizing an increase in confidence since the last time she had seen her.

"Really?" Dorothy questioned, her face contorting in amazement. "Interesting... I'm starting to like this world. Ooh! I just got an idea, too!" The witch-garbed woman lifted up one of her hands, which slowly flared up with pink energy.

"You see, where I come from, a birthday is often celebrated by presenting the person with a cake. Since Vivi already has all the milk you could need, I think that it would be fitting that she provide the cake as well!" With that, Dorothy's hand thrust out in the princess's direction, causing the pink energy to enshroud her form, too quickly for either the surprised Robin or Vivi to respond.

"Woah! Oooh..." Vivi exclaimed as bouts of tingling ran up and down her body, followed by a strange feeling she couldn't quite identify running through it. From Robin's view, the princess's skin slowly turned into a pale pink color as it gained an odd spongy texture. Up higher, her hair began to turn into a thick turquoise goo, and her eyes changed into a pair of orbs of violet fire. Vivi looked down at herself as her transformation into a cake girl completed, eyeing her unusual body with interest.

"Well, this is interesting." The princess noted as she raised a hand up to run it through her altered hair, bringing it away lightly smeared in the thick frosting her hair had become, flicking out a pink tongue to lap it up.

"Any part of you that gets eaten or melted off will immediately regenerate back." Dorothy helpfully added, "It won't hurt either, so don't worry about making use of that however you like, either of you." She finished, bringing a playful glance to Robin at that last part. Vivi seemed to share that sentiment, as she turned to give Robin a view of her in profile, her chest and rear thrust out.

"Well then, care to try me, Robin?" Vivi teased. Without waiting for an answer, the princess promptly brought her hands up to undo the strings of her bikini, letting it fall to reveal the heaving mounds that were her breasts, lightly coated with white icing and with thick, pink sprinkles acting as her nipples and areola.

An approving grin spread across Robin's face as she closed in on Vivi again and brought the princess into a hug, ignoring how the contact mashed Vivi's icing-covered breasts into her own top and cleavage, smearing them with the sweet cream as well. Reveling in the feeling of finally having her long-separated lover in her arms again, altered form or not, Robin leaned in to mash her lips into Vivi's, allowing the emotions built up between the two women during their time apart to storm through them. After continuing for over minute, the two finally reluctantly separated, Robin's eyes gazing into the violet flames that Vivi's now were.

"You don't mind if she watches?" Robin asked, obviously referring to Dorothy. Vivi merely grinned seductively, her fiery eyes doing an impression of going half-lidded as she regarded the historian.

"No, I've actually kind of wanted to try having an audience I don't know for some time. Thinking about it is making me rather hot already." Vivi purred as she ran her finger over Robin's chest.

"Really?" Robin asked in surprise. "You've gotten more adventurous since back then, haven't you?" Vivi's grin grew wider as she gave Robin another peck on the lips, leaving a little more of the pink icing that covered her lips on those of the historian.

"Oh, I'd say so." Vivi teased. "I've come up with more uses for my powers, too. In fact, if you want a taste..." The princess lifted up one of her breasts as she offered it to Robin, who noticed a drop of opaque pink fluid welling up at its nipple.

"Well, I certainly can't turn down an offer from you." Robin chuckled, and bent down to take the altered nipple between her lips. With a few sucks, a thick, sweet liquid with a taste not quite like anything she had ever tried before coursed down her throat. As she briefly backed off to ponder the flavor she had just been bombarded with, her eyes suddenly widened as a jolt went through her; images flashed through the historian's mind, of her doing things to Vivi with her powers, of Vivi doing things to her with hers, and simply of the two women entangled in various positions, greedily enjoying each other's bodies.

"Like it?" Vivi asked with a grin. "That was some of my perversions; I used my powers to 'milk' them out of myself. Fortunately, I have way more than that little taste to spare." Robin panted heavily as she recovered from the intense experience, more than a little amazed that the shy princess she had met only two years ago had now become such a sexual maelstrom that the flurry of erotic images she had just recieved was apparently only the beginning of the ideas that ran through her head.

"Oh my... I really created a monster, didn't I?" Robin laughed good-naturedly, Vivi giggling along with her. "Well, I really don't think I can hold back from you after that, so try this one for a start." Vivi grinned as she felt hands on the undersides of her breasts and on her spongy rear, courtesy of copies of Robin's arms appearing from the small of her back and her stomach.

Vivi sighed happily as she felt the historian's slender hands on her body again after so long, reveling in the feelings as they bounced her cake-formed breasts up and down and squished her batter butt about. As unexpected as the situation was, and despite how little she knew of it or the strange woman who made it happen, Vivi found herself determined to enjoy it as best she could. In the midst of enjoying the pleasant ministrations on her, the princess glanced back at Robin, a slight surge of gratification going through her as she realized that the growth spurt she had during the previous two years had, in fact, left her with curves that equalled those of her lover, even without the use of her Devil Fruit powers.

Not that she was going to ignore an opportunity to use those powers, Vivi thought with a grin. Two tendrils of regular milk made their way out of her nipples, and rapidly flowed through the air towards Robin, diving into her cleavage and wrapping around her breasts. The historian moaned in response to the stimulation as Vivi bounced her boobs about in her top, Robin eventually bringing up her original hands to unzip her top and shuck it aside, leaving the bobbing mounds to the open air.

Both women immediately took the opportunity to step up their efforts; Robin by creating two additional hands with a pair of lips puffing out on each palm to kiss and lick along the sides of the cake woman's breasts, and Vivi by causing the ends of her milk tendrils to swirl over to the historian's now bared nipples, flowing into her boobs through the pores in them. Vivi and Robin simultaneously moaned in pleasure, with the historian's breasts starting to pulse outward at the same time, swelling in size with the milk that poured into them. Robin also enjoyed the taste of Vivi's cake body as her copied mouths played across her breasts; while she usually preferred cake to not be so sweet, she was happy to make an exception for her princess.

Robin's breasts continued to pulse as more and more milk pumped into them, steadily swelling until they had grown far enough that their subtle teardrop shapes covered her torso down to her waist. The weight of the overgrown milk tanks was enough to force Robin to her knees, creating two arms under each boob to hold them up, though the historian still enjoyed their increased size and sensitivity, cooing as her original hands stroked the soft, smooth flesh. Still, she had enough presence of mind to continue focusing some of her attention on Vivi, and created more arms with lips on the palms of their hands, using them to lick and kiss up and down the princess's thighs, stomach, back, and neck.

"As much fun as this has been, we should get a little closer." Vivi chuckled as she swayed up to Robin, running her hands over the fronts of the historian's breasts, occasionally straying to the edges of her areolae. The princess's grin widened as her hands drifted further inward, caressing Robin's bulging, rubbery areola on their way to her nipples, and began flicking and stroking the enlarged nubs upon reaching them.

After several moments, Vivi finally took a firm grip on Robin's nipples, the historian watching in interest, and her eyes going half-lidded as she silently urged her lover on. Vivi complied, and squeezed Robin's nipples from base to tip, the piratess suddenly feeling an odd twinge in her mind as a murky purplish-black liquid gushed out of them, splashing onto the ground underneath her, where it soaked into the soil, gone forever. Robin somehow felt as though a weight was being removed from her shoulders and mind, as though her troubles were a little farther away, her memories of the past stinging a little bit less. After another tug that coaxed an identical burst of liquid from her thick nubs and a similar effect in her head, Robin looked questioningly at Vivi.

"That's another variation of the 'milking' I used earlier." Vivi explained. "I just 'milked' out some of your anxieties and stress. I just wish I had thought of this ability while you were still in Alabasta with me." Robin's hand immediately went out to stroke the side of the princess's sweet face, a grateful smile spreading across her face as she realized how much of a difference Vivi's efforts had effortlessly made within her.

"Thank you. This feeling... it's wonderful!" Robin breathed, before her voice grew huskier as she continued. "I think I should repay the favor, though, don't you think?" With that, two of the copies of Robin's arms moved to have their hands trail up the inside of Vivi's thighs, inching steadily towards the juncture between them. The princess's breath hitched, opening her legs a bit to allow easier access as her anticipation built, enjoying the tease of the hands's slow ascent.

Eventually, the hands reached Vivi's pussy, now a carefully crafted mound of hot pink frosting standing out against the paler pink of her cake body, with a large sprinkle at the top acting as a clit. Robin's slender fingers stroked the gooey pink lips, prompting a happy moan from Vivi, who pushed her hips forward slightly to invite more of the treatment. After a few moments of playing about with the icing nether lips, Robin brought one thumb up a little higher to toy with Vivi's clit a little, causing the princess's body to immediately seize up.

"Oooooh!" Vivi yelped as an orgasm instantly gripped her. Her legs shuddered as she struggled to stay upright, and a flood of white cake frosting erupted from her pussy, gushing out in waves that coated her legs, the fronts of Robin's breasts, and the ground underneath her. After several moments, Vivi's body calmed, and the flood of icing stopped, leaving the princess gasping for breath as she struggled to stand on quivering legs.

"Woah, that was something. Guess my clit's way more sensitive in this form..." Vivi panted, by that point leaning on Robin's massive breasts to hold herself up.

"Too much for you?" Robin teased, smirking up at the still trembling princess.

"Oh no, I can take a lot more than this." Vivi grinned back, managing to steady herself as she started to walk around Robin's huge boobs until she was next to the historian's body. "Now, let's see if you can take any more."

With that, Vivi plunged her thick, candy nipple into Robin's mouth, winking at the historian as fresh flows of milk gushed down her throat. A new shudder went through the raven-haired beauty's breasts, followed by the fleshy mounds bloating outwards even further, soon bringing Robin to dismiss the arms holding them up, causing the milk-plumped boobs to fall to the ground with twin 'thump's. The filling mounds continued growing as Robin eagerly sucked down Vivi's milk, soon swelling to the point that the historian could stand up while her boobs remained resting on the ground.

"Ooh, very nice." Vivi giggled as she ran a hand along the newly plumped flesh, watching Robin as she released the princess's nipple with a 'pop'. Relishing the moans that Robin starting giving in response to her caressing the sensitive flesh, Vivi continued for several moments more, before hoisting herself up onto Robin's mammoth mammaries, sitting in their cavernous cleavage with her spongy cake legs spread and her icing nether lips facing the historian's face.

"Care to get a real taste of your birthday cake?" Vivi purred, her violet fireball eyes sparking in amusement as she scooted forward slightly, just enough to put herself within reach of Robin.

"You know you don't need to ask that." Robin teased back, leaning her head in towards Vivi's tantalyzing pussy at a deliberately sluggish pace. However, the historian soon reached her target, and stretched her tongue out to the frosting folds before her.

"Ahhh..." Vivi sighed. The princess twitched about as Robin probed her sensitive nether lips, smearing its frosting on her tongue despite Vivi's perfectly formed icing pussy not seeming to change in any way from the attention. The historian avoided the large, beckoning candy clit for awhile, but soon couldn't resist Vivi's hair-trigger love button anymore, and moved her tongue to flick it about.

"Nnnnnnnngaaaaahhhhh!!!" Vivi screamed as her back arched, toes curled, and legs spread open just a little wider. Her frosting folds fluttered as gooey cake icing blasted out of them, coating Robin's face, neck, and chest, as well as pouring down her impossibly deep cleavage. The princess fell back onto Robin's mattress-like boobs as another burst of icing geysered out of her, her hands going up to mash about her spongy, icing-coated breasts.

"Alright, let's try this..." Vivi gasped out as her orgasm died down. As she continued her efforts on herself, her nipples thickened a bit, before they suddenly spread wide, a single odd pore at the end of each revealing a mass of white underneath as they gaped open.

A dainty, milk-white hand thrust out of both nipples, which steadily worked their way out of their sweet, wobbling prisons as arms steadily revealed themselves as well. Vivi's nipples stretched even wider as a semi-solid head and torso forced their way out, both of them identical to Vivi, save for the huge, puffy lips that the left one sported. As the new milk clones continued to pull their torsos free of the princess's nipples, a few other differences became clear; the clone with puffy lips had two additional arms, placed underneath her originals, both with another pair of plump lips acting as their hands, and the other clone had four extra breasts laid out in two rows under her usual set.

Soon the clones had pulled their hips free – the puffy-lipped one revealing that hers were particularly wide, supporting a butt twice the size of the original Vivi's – and finished slipping out of their original's nipples rather easily after that. The pair of milky maidens quickly slipped off of Robin's giant breasts and strutted up to the historian herself, each taking one side of her. The puffy-lipped one promptly brought her dainty upper hands to Robin's face and turned it to herself, and the many-breasted clone began gyrating against the raven-haired beauty, rubbing her six milky mounds against Robin's curvy figure.

Robin's eyes went seductive as she gazed at the milk clone before her, and unhesitatingly met her halfway as the milk-formed Vivi went in for a kiss. The historian reveled in the feeling of the warm, puffy lips pressed firmly against her own, which also brought her mind over to the second milk clone, whose own puffy masses were massaging most of Robin's form. The milk clone kissing Robin briefly pulled back, just in time for the piratess to notice her grin widening.

"Oh!" Robin yelped; a thick pair of lips, even plumper than the ones that had been kissing her face, suddenly mashed against her pussy, and promptly began kissing and licking her sensitive treasure. The raven-haired beauty was immediately set to squirming, and quickly realized that the clone was fully aware of exactly where to touch, to tease, and to lick for the greatest effect. Robin soon became aware of the clone's third pair of giant lips turning to lick and kiss what of her now-massive breasts it could reach, and continued to writhe against the second clone squishing her multitude of boobs against her, the sensations combining into a storm of pleasure that raged through her.

"Ooooooooaaaaaaahhhhhh!!!" Pierced the air as Robin came, juices pouring from her slit and straight into the milky lips that waited for them. The many-boobed milk clone held up the historian as she struggled to stand on quivering legs, and the puffy-lipped duplicate pressed her face-pillows into Robin's own lips for one more kiss. After several moments, Robin's body finally calmed, and the milk clones backed off.

"So, how was that?" Vivi teased from atop the historian's boobs, though when Robin turned toward the voice's source, the princess was already heaving herself off of the immense milk-plumped mounds. Vivi's squishy form strutted up to Robin, the princess pressing herself against the piratess as she planted another kiss on her lover's lips, her fireball eyes smouldering seductively as she pulled back.

"As fun as that was to watch," Vivi purred, "I want to give you your next orgasm myself." The milk clones then proceeded to walk around Robin's breasts toward their fronts while the princess stepped behind the historian and ran her slender hands down her back. After a few moments of the relaxing massage, Robin soon noticed two milk tendrils creeping in to the sides of her vision, briefly flowing slowly before instantly picking up speed as they darted down to her pussy.

Robin yelped as the cream swirled against her groin, though she soon settled into the feeling as she realized how soothing the warm caresses were. Vivi kept up her massage, only stopping occasionally to plant sweet kisses on the side of Robin's neck or nuzzling her face against it for a few moments. The historian drooped against the massive slopes of her breasts as her entire body relaxed, leaving herself open for Vivi to do as she liked.

Robin roused suddenly as she felt activity at the front of her breasts, and quickly realized through a new surge of pleasure that it was the milk clones, rubbing against and kissing the tanned flesh of the giant, sensitive mounds. The original Vivi intensified her efforts as well, moving her hands down below Robin's waist, then drifting up her skirt to begin squishing about her plush butt. The milk the princess had swirling over the historian's nethers reacted by surging inside, becoming a semisolid mass that pushed rhythmically in and out of Robin's slit.

Robin's moans intensified as she felt the milk clones turn their attentions to her bulging nipples, one clone planting kisses all over the thick nub, and the other squishing it between her multitude of plushy breasts. Combining that with the steadily increasing speed of the milk tendril inside her and the ominous gurgling coming from within her breasts, Robin figured she wouldn't last much longer. Quickly focusing her failing concentration, the piratess created a copy of her arm on Vivi, a new mouth opening on its palm, then turned it down onto the princess's clit, taking the candy nub between its lips and sucking for all she was worth.

The two women's screams rang out as they both came simultaneously. Vivi's legs shook as another deluge of cake icing exploded from between her legs, splattering all over the lower bodies of both women; Robin's geysering fluids came from further up, her engorged nipples releasing rivers of milk as her breasts slowly began to shrink down. Princess and piratess held each other tightly as they rode out their climaxes, nothing else mattering to either of them in that moment but each other.

Eventually, the lovely pair started to calm, with Robin's gushing boobs nearly back to their original size; the two then noticed that all of the milk coming from the historian floated through the air, as if by Vivi's powers, except that it was all traveling toward Dorothy, who had lowered the top of her robes to reveal a fairly large pair of breasts, both of which had a pair of plump lips in place of their nipple. As the two watched, the flood of cream disappeared into the two sets of lipples, the oddly-placed mouths happily gulping it down until there was no trace of it left, not even in an increased size for the witch.

"Hope you don't mind." Dorothy chirped, as she pulled her robe back up. "I simply didn't want that milk to go to waste. Are you done?" Vivi and Robin stared for a moment where the strange woman's even stranger breasts were once again hidden underneath her robes, but quickly recovered.

"Not quite yet." Vivi smirked, as she brought her hands up to Robin's nipples again. With a few tugs, the princess coaxed a few sprays of a light red liquid from the historian's nubs, which again vanished into the grass beneath them. As the odd fluid left her, Robin immediately perked up, any traces of exhaustion from her exertions that day effectively erased.

"My fatigue?" Robin quickly guessed, earning a grin and a nod from Vivi. After planting one more deep kiss on her lover's sweet lips, the two turned to face Dorothy.

Some time later, Robin was walking through the forest again, making her way back to Luffy, Usopp and Chopper. Sure enough, Dorothy had kept her word, restoring Vivi's original form before teleporting her back to the Alabasta Kingdom. She then assured Robin that the screams she and Vivi had let out would go unheard by the others, and that her absence also would not be noticed, before finally waving goodbye and vanishing in a cloud of pink light.

Once again, the historian's trip through the foliage was both uneventful and quite easy using her powers, and she soon came across the immature trio she had originally entered the wooded area with. The three seemed to be finishing up with their fun, having had their fill of chasing Hercules Beetles around, and even managing to catch a few. Robin smiled happily at the sight, glad to see what was effectively her family so happy.

"Hey, Robin!" The trio yelled as they rushed up to the piratess, waving their new trophies in the air; as they drew close, Chopper's face suddenly gained a contrite look as he gazed up at Robin. "Oh, but you've been standing here all this time not having any fun yourself, have you? I'm sorry..."

"Don't worry about me." The historian chuckled as she pet the back of the man-reindeer's head. "I had plenty of fun." The other three apparently satisfied by that, the quartet of pirates then turned to head back to the Thousand Sunny. A new brightness seemed to infuse Robin's smile, the raven-haired beauty's visage shining with love for a certain desert princess.

* I only realized just now that you guys here at HF would have no idea who Dorothy is, considering I haven't posted any of her stories here. She is actually the main character of an original series of mine called "Art of Witchery", basically an excuse for all kinds of crazy transformations, much like the one Vivi received in this story. I hope that doesn't detract from anyone's enjoyment.
