Nico Robins Experiment

Day 1: Preparations

Chopper was just as excited as I hoped he would be, testing out the sexual capabilities of each of his forms will be a breakthrough in devil fruit studies everywhere! The Sunny has is out of commission due to our last navy run in and it seems we will be stationed at this island for quite a while. I have already rented out a cabin thanks to Nami's secret stash of gold, and tomorrow night Chopper and I will discover everything the Human-Human fruit has to offer.

Day 2: Base form/Heavy Point

Waiting for tonight was unbearable, but the minute dusk fell we hurried off to our little cabin in the woods and immediately began our studies. Setting Chopper up on the bed he was obviously nervous, as he confided to me that this would be his first time, but he was trying so hard to look "manly" I could not help but chuckle.

"what are you laughing at?!" The little deer exclaimed

"I just cant get over how cute you are"

I wasn't lying, from the moment I joined this crew I fell in love with the fuzz ball, all the more reason I yearned to pull down those red shorts he always wore, and without warning I gently pulled them down exposing Chopper to me. His face turned a bright red, but he did not move, the only thing that moved was his member that just could not stop twitching in my face. For such a small body he was not anything to laugh at now. More girth than length, but due to his devil fruit ability it resembles more of a human shape rather than a deer shape, strangely it has a red hue and his testicles are unlike that of a human male as they are in a "sheath" probably due the natural color of a deer's penis. The Musk was irresistible, a scent I have never smelt before that entranced me, and without hesitation I slowly started working the shaft. Chopped let out a cute flinch, followed by immediate sigh of euphoria as I began to work my magic. The smell was too much, and I just had to taste it and slowly I licked the head of the penis. The taste of his pre was unlike any human, very strong and more thick than human sperm, but as I began to work down the shaft chopped grabbed my head with his tiny arms and I could tell by the twitching that he was about to cum.

"R-Robin I-it feels…"

And before the boy could finish his sentence a thick rope of sperm was being launched down my throat. Such volume for someone his size but considering its his first time its no surprise. I swallow every drop and lick my lips clean of any I may have split, delicious is all I could think.

"Robin...I'm sorry I didn't last long enough…" The deer looked a tad disappointed

I simply smile and remind him the night is not over as I remind him of the actual experiment at hand

"we still have 7 more forms to go through, and I'm sure that devil fruit of yours gives you at least some energy back in certain areas when you transform"

Without hesitation Chopper transforms into his "Heavy Point" and since I was still standing in front of him, and with his massive increase in size his flaccid member is directly in front of my face and transform he did. What was once a nice well-rounded cock, has turned into truly that of a monster. Resembling even more of a human shape in this form than before, losing the red hue and even gaining heavy testicles that descend from the body like that of a human male. The size is easily triple that of before and its not even hard. I decide to fix that by undoing my blouse and exposing my breasts to Chopper. I've never seen him drool like that even at Sanji's food, and within seconds his member was poking me in the nose begging for release. To say it was big was an understatement and with added veins popping off the sides it was driving me wild. Apparently, I was not the only one going wild, as I felt choppers massive hands pick me up and switch spots with me face down on the bed in front of his massive figure. There was a tint in his eyes that I have yet to see and before I felt any fear, I felt an intense amount of arousal. Before he even put it in, he laid it out on my stomach, smacking it just near the top of my entrance. It easily reached my belly button and it had some weight too it. Finally, he backed up and aimed at his prize and just as he touched the tip to my hole, he said something I will never forget

"Robin, are you ready?"

The young boy was simply acting like the rough and tough alpha male, but Chopper is still more kind hearted than any man I've ever been with, those 4 words mean the world to me after years of being taken advantage of and abused, and with a simply yes he slowly pushed his way inside. Never have I felt so full, he was able to get to his base and I could feel his head poking the inside of my uterus. No other feeling could compare to this pleasure and I needed it bad. The combination of the Musk and the slow caring speed at which chopper is fucking me was making my mind numb. All I wanted was for Chopper to fill me to the brim, I wrapped my legs around his thick waist and grabbed on to his neck. Chopper followed through by lifting me in the air, and as gravity forced me down on his massive cock all I could muster was a moan of

"Faster"

Chopper obliged and began bouncing me his thick shaft, hitting spots that I never even knew could be hit. My mouth could not stay closed, and all that I could do was moan with pleasure every time he shoved it deeper into me. Chopper was picking up speed I could tell he was going to cum. Before I knew it though I was laid back down on the bed with my hands held behind my head and choppers eyes right in front of mine, and with one final powerful thrust Chopper unleashed everything he had and filled my womb like nothing I ever felt before, yet at the same time he leaned forward and kissed me with so much love that I never wanted it to end. He eventually pulled out and rolled over next to me making sure to never lose my embrace.

"I love you Robin" The Deer said as he transformed back into his base form, before quickly falling asleep. Though I can't blame him for how late it is and how excited he must have been today. I kiss him on the cheek and fall asleep beside him as i can only dream what his other forms have to offer.
