Okay so I haven't gotten a message about having problems with me changing this story around a bit, so I'm going on ahead and going with the idea I had for this so it's not over stepping some lines. Just so everyone knows, the limited time offer I put up with the last chapter I had to update it to verify a bit more. I wasn't meaning find a picture on the internet and send it to me, I was meaning more like create a picture and send it. If I used picture you sent to me from another author, it just takes longer to get verification from the author to use the photo, and if I can't get the authorization I can be counted against copyright.

Only a few more are left on the list! I can't believe it's almost over! Thank all of you for the nice comments and messages! I really love hearing from all of you! Don't be scared to PM me!

This chapter was requested by Sgt M00re. I hope you like it my dear! Thanks for requesting!

The next story is for mrdbznarutofan who wants a SaboXRobin story! I'll try to get that out before I go on our road trip! But I can't make any promises since I'll be busy packing and prepping for the trip and stay!

Chopper knew the time was coming soon, but he didn't think it would race up on him like it did. He must have lost track of time. His body felt hot, not like any fever he's ever had or seen before. It was like a burning fire that was slowly trying to melt his body from the inside out. That was the first clue. The second was that his mind seemed to get foggier and foggier. He couldn't remember the simplest of things in his medical knowledge; all that was there was a wild instinct that he blushed at the mere thought of.

"Doctor-san? You okay?" Robin asked, leaning over Chopper as he sat on the grassy deck of the Thousand Sunny.

He looked up with clouded eyes and his chest heaving a little faster than normal. She was sure that if he didn't have fur his cheeks would be red as well. Robin reached her hand forward and placed it on his forehead, her arms pushing closer together as the other balanced her on her knee. Chopper quickly pulled back and bit the inside of his cheek, his eyes focusing on the cleavage that was protruding exorbitantly, causing his thoughts to become bad once more.

"I'm fine!" He chuckled fakely while jumping up and pulling his hat down a little bit over his head. Before Robin could say anything more to him, he dashed off back to his office and slammed the door.

"That was odd," Nami said, walking next to Robin with one eyebrow cocked in confusion. She had seen the small spectacle from her spot by the mikan's and came down.

"Wo-ho!" Luffy shouted in glee as he sat on the railing of the ship and pointed out to sea at something.

Everyone gathered off the side (aside from Chopper) and looked over at two large dolphin type creatures jumping over one another and yipping. It was as if they were in a dance with one another as they zipped, flipped, and rolled around each other, the water flying into the air like shining light.

"Must be mating season," Sanji said, taking his cigarette and flicking the ash while blowing out the smoke. "I guess it is around that time."

"Mating season?" Luffy asked, his head tilting to one side.

Nami groaned and gave Luffy a quick punch to his head, telling him to not be oblivious in this sort of matter. The last thing she wanted was to explain to her captain what the birds and the bees were. "Do all animals go into mating season around the same time?"

Sanji looked at her with heart eyes and a beaming smile, glee overtaking him that she was actually finding interest in something that he was knowledgeable about. "Of course Nami-swan! Though not exactly the same time, but very close!" A sudden idea popped into his head as he looked over Nami who looked satisfied with the answer. "We must take the chance while we have it to strengthen our own love!" He jumped at her in a frog kind of way, hoping to land on her with an embrace, but she easily stepped aside and instead he flew into Zoro, knocking the two of them into the ground with their limbs tangled and their mouths crashing into one another.

"You stupid cook!" Zoro shouted, flinging Sanji off, who looked equally as angry as the swordsman.

"You idiot Marimo! It's your fault I missed Nami-swan!" He shouted back, trying to push blame onto the one person who was his rival.

The two women sighed and shook their heads, knowing this fight was going to get dirty fa…..And they were throwing each other around the deck already. Worse yet, Luffy was jumping into the fight as if it was a game.

"Let's just hope they don't destroy the ship." Nami said, knowing it was impossible to stop them when they were already on a tirade like this.

"Mating season huh?" Robin whispered, her hand propped up by the elbow and her pointer finger touching her lip. Light bulbs were flashing in her mind as she connected the dots. "I wonder if Chopper-san is having to go through that?"

Nami blinked and then remembered how he was before. It seemed to make sense to her just as much. "Poor guy, he probably doesn't know what to do either."

"GAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHH!"

Just as they were talking about him, a loud blood curdling scream came from the office Chopper staid in, alerting everyone and even stopping the fight between the boys. Everyone ran over to the door and slung it open, expecting to see some kind of invader inside the room with him, about to kill him, but instead they saw neither an invader, nor chopper inside the office.

"Chopper?" Nami asked, taking a small step inside of the office and peering around hesitantly.

His white lab coat he wore occasionally when working on herbs was on the floor and a small lump could be seen underneath it. It wiggled slightly, making her jump and look at it with a raised eyebrow. She reached out her hand towards the bundle, and then quickly pulled it back and retreated towards the door as the lab coat shot up and dropped to the floor. There sat a shorter tanned boy with light brown eyes and shaggy light brown hair. His eyes were as wide as a deer in head lights. He had to be only a year or two younger than Luffy, but was obviously lacking in height.

"A-are you okay?" Nami asked, walking over to the boy quickly and lifting the lab coat over his bare body. "Who are you? Where did you come from?"

The boy looked at her with wild confusion running across his face, and then tears welled up in the bottom of his eyes. "N-NAMI!" He cried out, wrapping his arms around her neck and hugging her.

That voice sparked recognition in her and Nami could hardly believe what she was thinking! But it couldn't be! "Chopper?" Robin asked for her from the doorway, peering in closer to take a look at this mystery.

"No way!" Usopp shouted next, staring in awe at the now human chopper who was in his late teens and looked nothing like his reindeer self.

Nami forgot how old Chopper actually was. Though in his reindeer form he seemed like he would be a child, he was actually about 17 years old. It also threw her off guard that he was now hanging onto her while completely naked, but he seemed just as confused on what to do as she was.

"Robin," She said, glancing at the dark haired woman.

She seemed to catch the hint and nodded her head before ushering the men away from the office and shutting the door behind her. "Now let's get him into something before he catches a cold." She said, pulling open a small door with extra clothes inside they used in case a guest came aboard.

They fixed him up as best as they could and tried to calm him down. But they could only do so much for him against the rest of the crew at dinner time since they were all curious about Chopper and what all had changed about him (though it was pretty obvious to the girls).

"Time for bed!" Luffy said, all too excited about continuing their investigative fun on Chopper while the girls were not around to stop them. He grabbed Choppers arm and began to pull him towards the rooms.

"No!" Nami shouted, hitting Luffy over the head once more. He stopped in his tracks and grabbed his head, a shout of pain coming from him. Nami and Robin scooped Chopper towards them and held him between them, his face covered into their boobs from either side. "he's staying in our room tonight!"

"Why?!" Usopp shouted, feeling deflated that he didn't get to investigate either. It would have been a great story to tell people another time.

"You think we'd let him be experimented on by you guys?" Robin asked, raising an inquisitive eyebrow at them.

All their faces turned guilty until they finally gave up and slinked off towards their rooms in defeat. No way were they going to enrage them and make their sentence even worse. Plus it didn't seem like Chopper minded as he was limply standing there between them, while he kept pushing away the guys since the incident first happened.

"Don't mind them," Nami told Chopper as they shut their door to the large girls bedroom. "I'm sure you'll be back before you know it and you won't have to deal with that again."

Chopper sat idly on the bed, looking at the two girls in a blank stare. They figured he was still in shock as to his new form, and exhausted from the guys pestering him non-stop. They paid no mind to him as they slowly stripped off their shirts and skirts, looking for the pajamas they normally slept in. To them Chopper was still his usual self…but they forgot about the root problem of why he changed into a human. He didn't change because of his high temperature, or because he mating season was close per say, he changed because humans were the only beings on the ship. The survival of the fittest as they say. Because there were no other reindeers, and because he had the abilities of the devil fruit to change, his animal side decided to retreat to only his mind and let the human part of him take over, transforming him into something that would allow him to accomplish his wild goal.

With the two women in front of him suddenly very bare and only in their panties, it left his human side shocked and speechless, while his wild animal instinct side took over. Before either of the women knew Chopper had stood up from the bed and grabbed their arms. He turned quickly, slinging them to the bed until they lost their balance and fell. They laid face down on the bed in confusion in shock with Chopper hanging onto their wrists.

"What are you do….!" Nami began to argue before he turned her arm behind her back until it felt like her arm would pop out of socket. She looked over and saw he was doing the same to Robin, leaving them both incapacitated and unable to fight back.

She glanced back at Chopper, ready to try and argue once more, but a shiver went down her spine as she looked into his eyes. It was a wild look only an animal could have; as if they were prey he just caught. A sharp smile crossed his face with a sigh, and Nami felt it deep in her gut why he was this way. She turned her head and buried her face into the sheets in front of her, letting out a groan as she came to a conclusion.

"Fine!" She said, lifting her head back up and looking at Chopper. She reached her other hand back, and Chopper squinted his eyes. But she wasn't going for his hand holding hers, nor him himself; instead her hand reached just far enough to reach her panties, tugging on the hem and sliding them down diagonally as far as she could on her thighs. "If it'll make you calm down….." She blushed and turned her face back towards the sheets, feeling more than embarrassed that she was having to do this.

Robin felt his hand let her go, letting her relax her arm back to its normal position. She looked over at Nami and Chopper, who was now completely behind her. His hand had let her go as well, but Nami made no move to run from him. It seemed to Robin that Nami was actually a little turned on by all of this. Her hips quaked already and her breathing was already labored in anticipation for what was to come. But what really surprised Robin was what came next. Though Chopper was lacking in height and bulk, he made up for in another department.

Robin sucked in a breath at the sheer size of it. She didn't know it could grow that much when he was in heat…..it made a shiver go down her spine, and she was unable to move from the bed. Nami started to lift her face, wondering what was taking so long, and why Robin was sucking in her breath suddenly. But before she could turn her head even in the slightest, Chopper had already thrown off the boxers he had on and slammed into her.

"Ah!" Nami couldn't stop the moan that came out of her, stars flew around her eyes, and she could have sworn she just had her orgasm right there. He had hit so deep inside of her, pushing slightly into her womb that was now throbbing in pleasure. She tilted her head ever so much to look back at him and felt a large shiver go down her spine as she realized he wasn't even putting his full length in her just yet. He pushed into her little by little, urging her cervix to spread open and give him more room to directly hit her womb. Another moan came out of her, and her hands desperately grabbed the sheets to hang onto reality. "More. I need more." She begged into the sheets.

Chopper's attention flicked towards her, some of his sense coming back to him. He leaned forward, a smiling on his face once more. He nipped her shoulder, making her gasp in pleasure and shock. Then he licked the small spot that was turning red and leaned to her ear. "My pleasure,"

His hands grabbed her hips tightly, leaving her in place as he pulled out of her nearly completely and slammed back into her, finally putting his length inside of her while forcibly opening her cervix. The walls clamped down on him, sucking him in and trying to get him to hold still, but he knew that wasn't what she really wanted. Her hips were wiggling and trying to push towards him, grinding her walls against his member.

"Don't worry." He said in a deep husky voice, so unlike him. "I'll give you just what you need."

He put his speed to use as he thrusted into her repeatedly, hitting the top of her womb and sending her mind into chaos. Every time he pulled out her walls that were clamping on him tried to push back together, but they never had enough time as he sliced them apart once more and stretched them.

"Ah~ Oh~ CHOOOOOPPPPPPPPER~" Nami groaned, her body rocking with the force of him thrusting into her.

Her body felt like it was caught in a lightning storm; electricity shooting everywhere inside of her. Her walls pulsed inside of her with every slap of flesh against flesh. His balls hit against her clit with every thrust and it made the electricity even more arousing and strong. Nami felt his cock swelling even more inside of her, but he wasn't giving any time soon. But her own orgasm was already almost here.

"AAAAAAAAH!" Nami moaned loudly as he put more force behind his thrusts. "Chopper, I can't take it…..mm!...anymore!" She begged, looking back at him desperately. "I'm going….mm!...to cum!"

"Me too Nami!" He grunted, face strained as he tried to hold back for a little bit longer. His thrusts became erratic and seemed to not hardly be pulling out from inside her womb. It was his animal instinct telling him he had to get the most direct route to her eggs.

Nami gasped, figuring out what he was doing. "No! Not inside!" She begged, reaching back towards him. She tried pushing on his hips, but it wasn't pushing him any more out of her womb. "No! MMMMM!" Her back arched quickly as his cock swelled to fill the little space her cervix had around him, blocking the hole completely. Hot liquid poured inside of her, filling her womb.

Nami collapsed forward onto the bed, her muscles clenching and relaxing as it moved and sloshed the liquid around inside of her, giving the seeds more of a chance to reach further into her. Chopper's cock seemed to finally relax enough that he could pull out of her. Some of the liquid seeped out of her and dripped down to the floor as he pulled out, showing just how much he let out inside of her.

Chopper let out a deep breath, feeling relieved from some of the pressure of the instinct lift up. But it seemed a sweet scent that drifted over to him caught his instinct all over again. Before he knew it he was standing proud ready to go again. He looked over at the other woman, he had forgotten was there, and saw her flushed cheeks and her shaking hand that was placed just over her panties. A small dark spot could be seen under her as her wet juices had seeped past her panties and onto the bed.

"Did you think I wouldn't give you attention?" He asked, taking the few steps over to Robin to stand directly in front of her.

Robin jumped at his voice and got off the bed, ready to try and rush out of the embarrassing situation she was caught in. Chopper reacted faster though as he grabbed her wrist and yanked her back over. She spun around to catch herself, and found herself facing down on the sheets again. A hand ran itself along her back and down her cheeks, feeling the soft plumpness of them.

Robin bit her tongue, holding the moan in her mouth and try to stop the shiver from running down her spine. She turned her body, hoping to keep him at bay and block him. Yet there it was again, that glint in his eyes that told her she was his prey. It froze her for an instant, allowing that shiver to course down her, and giving him enough time to grab her leg as she lay on her side and pull it upwards. He hooked it over his shoulder, and straddled her other one so it couldn't move.

"Ah! Wait!" Robin said, holding her hand towards him.

Chopper paid no mind to her plea's because he could see how wet her sweet spot was and she could easily take her leg off his shoulder, but she kept it there. Her words were saying the opposite of what her body truly wanted. He ignored those words then and complied to her body. This time he plunged into Robin from the side, scraping her walls roughly as they were spread apart and the tip of his cock slammed into her cervix.

Robin's head lolled backwards as the breath was knocked out of her. It was as if he were filling her stomach completely with his cock, and the way it scraped the her walls made it feel like he was trying to mold her to his cock. Now she knew why Nami had no control; it was as if all control is thrown away the moment he pushes in. Her hips jumped in a begging sort of way as he stood still in front of her, waiting to see if she would argue against him again. But nothing was said.

"Done fighting against your own animal instinct?" He asked in a gentle way, not really wanting to force her into something she really didn't want.

Robin kept stubbornly quiet as she bit her lips and caught her breath. Her wavering eyes stared at him with a slight rebellion, but still no move was made to go against him. He decided to try and coax it out of her. He pushed into her more, sliding past her cervix until he was completely sheathed. Slowly he ground his hips against her, moving his cock around inside of her and stirring her insides up. But still Robin didn't say a word, which frustrated Chopper a bit. It wasn't good if she didn't want it.

"Fine, I'll stop then." He gave in and pulled out of her, letting her walls relax against themselves again. A cool air brushed against her folds as he completely pulled out of her, and a unpleasant burning sensation crouched through her in irritation at herself for letting him leave her insides.

"Wait!" She stopped him, but then clamped her mouth shut again. She sighed and placed an arm over her eyes, feeling all the more embarrassed that she was giving into him, just like Nami did. "Please, put your cock back inside me." She didn't know what made her say those words exactly, but it was like her body was replacing her words with it's own. She peeked from behind her arm at his shocked face, seeing the small boy back in him a bit. Her eyes traveled over to Nami who was still in bliss, but now fully on the bed so she wasn't hanging off. Her body so badly wanted to feel that. She reached down to her folds and spread them apart to show him how wet she was, and her walls twitching, ready for him to enter her once more. "Please fill me up as well?"

Chopper didn't have to be begged again. He gripped her leg on either side tightly and thrusted into her so hard she bounced at the force. Her hands dropped and covered her mouth instantly, trying to cover the loud shouting moan that was trying to escape her. She couldn't wake up the guys down the hall. A hand grabbed her own and pulled it from her mouth.

"Let me hear you scream," He said in that husky voice once more that made Robin feel electricity run through her in pleasure.

He slammed into her deeply, hitting the back of her womb and pulling on her cervix, as if he was trying to pull it towards the outside with him. She bit her tongue harder, trying to keep quiet and not make to much noise, but Chopper liked to hear their voices, and wanted to hear the lewd sounds that came from them. He was going to have to up the pleasure then and play dirty. He moved one of his hands down her leg, letting his fingers trail along the soft skin and cause more shivers to go through her. He reached the spot he truly wanted, pressing his thumb against the small bulge that was at the top of her folds.

"AAAAAAAHHHHHH!~" Robin couldn't stop the moan this time as the pleasure inside of her seemed to become too great to stop. With every thrust he pushed inside of her it seemed another small moan would come out. "Ah!...Ah!...Ah!...Ah!...Ah!...oh!... mm!..." She couldn't stop them now.

His thumb continued to knead the small bulge, making her walls clamp tighter around him while her orgasm drew closer and closer to it's peak. He picked up the speed and intensity once more, trying to catch up with her so he wasn't stuck outside of her womb when he came.

"More! More!" She begged in an airy whisper, hardly able to catch her breath through the intensity. She clenched her teeth hard feeling the spring coil up to the tightest it could inside of her. "MMMMMMMMM!"

The spring released and her walls clamped down onto Chopper's cock. He winced at the tightness and nearly came himself, but he forced himself to push one more time through her walls and into her cervix, feeling his girth barely making it passed the small opening. The hot liquid poured out of him and into her womb, sloshing around inside of her as her hips jerked with every contraction of her orgasm. Chopper felt every ounce of strength leave him as he pulled out of Robin and sat on the ground with a plop, his cock now withered and exhausted.

"That…." Nami breathed heavily, looking at Robin who looked just as much in bliss as she.

"Yeah….." She answered, not even needing the orange haired girl to finish her sentence. They both knew what they were going to say, and what they were thinking.

Chopper climbed into the bed between them, helping Robin get to the top where the pillows were before falling backwards onto the bed with a gleeful smile. "Ah! Now it's time for sleep!"

The girls looked at one another in slight shock before giggling. Chopper's personality was back to normal now and the sudden change nearly made them burst out in fits of laughter. Who knew someone so childish and innocent could become so forceful when his instinct came out? Before they realized it all three of them had drifted into nostalgic sleep with smiles on their faces.

"Awwwwww! He's back to normal!" Luffy whined as the girls and Chopper ambled out of their room.

Chopper smiled at Luffy and let out an embarrassed chuckle. He scratched the back of his head before apologizing them for the worry. He explained that he was feeling better and that it shouldn't happen again for a long time.

"That's good though." Sanji said, taking a puff of his cigarette. "If you had staid in that form for long who knows what you might have done to the girls." He swooned around the girls describing how he'd be their knight and protect them. "After all during mating season they say that an animals seed is much stronger and has more of a chance of reaching it's destination."

Robin and Nami looked at one another in a confounded kind of way as both of them thought 'oh boy, this is going to be hard to explain.'

Guess they'd have to explain it when the time came, but for now they'd keep it their own little secret.
