PREFACE This story uses characters from the anime One Piece. It features extreme BDSM and does contain human-toilet slavery. If you do not like scat, it is not featured prominently until the chapter titled “Saturday,” and any involvement is not highly detailed until then. Here are some short blurbs about the characters featured: -Nico Robin: The archaeologist of the Straw Hat Pirates. She is quiet and mysterious, and sometimes displays a taste for the macabre side of things. She has the ability to make any of her body parts “bloom like flowers” out of anything, such as making hundreds of arms appear out of a wall. If an outfit of hers is described by a title in quotes, it is highly recommended to do an image search to aid in your imagination. (For instance, search: Nico Robin “Water 7” outfit.) -Black Leg Sanji: The cook for the Straw Hat Pirates. He is very flirtatious towards women, especially the two female Straw Hat Pirates, Robin and Nami. Any kinks, fetishes, or orientations indicated by the characters are not necessarily reflected from the source material, and are not intended to represent the actual feelings of the characters. It's entertainment, don't get too offended if you don't agree with something. PROLOGUE Sanji fidgeted nervously as he made the finishing touches on the Nigiri sushi that Robin liked so much. The others had finally gone off on their mission, leaving them to guard the ship and old castle in their absence. When the topic of who would have to stay behind with the ship came up, Robin had happily volunteered herself and Sanji for the task. His cock throbbed in its cage at the thought. “Alone with Robin...” he thought to himself, “and for a whole week!” Her eagerness to stay behind with him CLEARLY indicated that she had something in mind. His knees wobbled slightly as he grabbed the platter and headed out onto the deck. Robin was sitting on a beach chair under a parasol, reading a book. She was wearing her dark blue sundress that was both low-cut on top and high-cut on the bottom. The sexual energy she radiated caused Sanji to forget his task and go into full-on jelly mode. “Those look delicious, Mr. Swirly Cook,” she said warmly, slightly snapping him out of his reverie. She chuckled lightly at his bewildered face when he looked up to meet her eyes. They were big, blue, and piercing right into his soul. The intensity of her stare caused him to sputter something incoherently while handing the plate of sushi to her before lowering his eyes. She was reading “The Art of Female Domination: Breaking your Slave” again. Again, Sanji felt a surging tremor shoot through his cramped cock. That was the same book she had been reading over a month ago, when he had walked in. On that day, she had been a little embarrassed to have her interests discovered, but was quickly reassured by Sanji. He had, hastily and excitedly, informed her that he would be thrilled to be her slave. “Would you really? Slaves don't get to have much fun, you know,” she had asked with a hint of a mischievous smile on the corner of her beautiful mouth. As blood began to pour from his nose, he started begging her semi-incoherently, falling flat on the floor, promising that he would be the best slave she could ever ask for, and that he would do anything at all she wanted, whenever she wanted. “Oh my. I'll have to think about it,” she had said with a chuckle, but in a noncommittal voice. Contrary to her voice, she had a look of excitement in her eye. “Think about whether or not that's something you would really want.” At night that same day, when the crew returned to the ship after a full day of resupplying in town, Sanji was the first to rush off to the shower. Robin snuck away from the group to go after him, catching him right after he got in, throbbing boner already in hand. “Are you thinking about something naughty?” she asked coyly as she stepped over to him. “N-nothing!” he practically shouted at her as he clumsily and desperately tried to cover himself, blushing furious red all over his entire face. “Have you been thinking about our conversation earlier?” she asked, looking up at his eyes. Sanji looked away, desperately trying to avoid her hypnotizing stare. “Of course not!” He kept trying to cover himself while inching towards the towels, but she would have none of it. Robin planted herself firmly between him and his goal. “No?” she said in a faux-disappointed voice with a hint of amusement. “I did ask you to think on it.” “I mean, yes! But not in any indecent way!” Sanji said. “I wouldn't!” “Where did that 'lady's man' confidence go?” she asked playfully, but spoke again before he could respond. “What do you think, then? Would you stand by what you said earlier?” “Yes!” he croaked excitedly, just as hastily as before, despite his current predicament. “You will be the best slave I could ever ask for, and do anything and everything I ask of you?” Robin asked in a warm, sweet voice while staring intensely at him, electric excitement in her eyes. All it took was one final drop of his eyes making contact with hers, and Sanji began blubbering. “Yes! I swear to be your slave! I'll make you so proud, you'll never regret it!!” “I'm sure you'll be perfect,” Robin cooed at him, giving him a big smile that turned him into a pile of mush. “From now on, you are mine and mine alone. You are not allowed any sexual pleasure without my explicit permission. Of course, you will do as I say. Firstly, put your hands behind your head. I would like to scrutinize my new slave.” Sanji hesitated slightly, before complying and removing his hands from his crotch. His erection stuck straight out, causing his blush to deepen even further. Robin walked a circle around him, looking him up and down, before kneeling down to get a better look at his cock. It was fairly big, measuring around seven inches with a moderate thickness, and was trembling like the way a taut violin string vibrates when a note is played. The head was, of course, just about as red as his face. “My my,” she teased. “I had no idea you were so endowed.” She leaned even closer to inspect every inch of it, her breath causing him to shiver. “I wonder if it's as hard as it looks,” she cooed as she extended a single finger and slowly moved it towards his now pulsating cock. “N-no Rob-” Sanji began, but it was too late. Even before her touch, his orgasm had reached the breaking point, and on contact with her finger, large blasts of thick white cum spurted from his cock. When he calmed down and opened his eyes, he looked down to see Robin staring up at him, with her patented ice cold stare on her now cum-soaked face. “S-sorry! I'm so sorry! I didn't mean to! I couldn't help it, I just-Ah!!” he carried on. She stood up without breaking eye contact, then promptly grabbed his sniveling cock. Wordlessly, she pulled him over to his still-running shower and began to rinse her face off while keeping a firm grip on his dick. When she was done, she turned off all the hot water. “You weren't supposed to do that,” she said in a calm voice, glaring at him again. Before he had a chance to say anything, she forced him into the ice cold shower, turning the water's bite fully on his spent cock. Sanji shrieked as the frigid water made painful contact with his sensitive flesh. He tried to back up away from the torment, but a hard squeeze and a large smack on the ass told him that he had to endure it. When Robin was satisfied, she said, “You will be punished eventually. But right now, I have a gift for you,” and pulled a small metal device out of her pocket and fastened it around his cock and balls. It was much smaller than his erect cock, and made of steel with many slots on the sides. “You know what this is?” she asked mischievously. “I got it in town today along with plenty of other fun things.” Sanji's heart began to sink as he realized what was happening. “This little cage will keep your equipment locked away until I let it out.” She clicked the lock shut and stood up, looking him square in the eye. “Only I have the key,” she said, pulling out her key-necklace to show him, “and I don't think Nami would pick the lock for you.” Robin grabbed his cock cage and gave it a few wiggles for good measure, then turned around and began to walk towards the door. “W-wait! Robin!” he said, causing her to swivel around with a small smile. “Yes?” she asked sweetly. “How long, I mean, when will... we...?” he trailed off helplessly. Her smile broadened, “When will you serve me? I don't know, we will have to see. You won't need your penis until then. Besides, it looks much smaller and cuter in that tiny cage.” She winked her big beautiful blue eye at him and left him to shower alone. In the following month, the cage became incredibly frustrating and downright unbearable for poor Sanji. Being forced to be in a confined environment with Nami and Robin, both usually skimply clad and well versed in flirting with him for favors, did not help very much. The worst part of the torture was that Robin did not act like anything was different at all. She did not so much as wink at him the entire time, leading him to sometimes question whether or not he had imagined the whole thing until the cage's steel embrace reassured him. The one and only time he had worked up the nerve to approach her and gently ask if she would allow him some time with his cock, she had informed him that he was already in trouble for cumming on her face, that punishment was already coming, and that by asking her, he had made his eventual punishment worse. “We have a week to ourselves,” Robin said pleasantly, snapping Sanji back to the present. “We do!” he said, hearts in his eyes and excitement in his voice. “I take it you are happy about this?” she said, with a big smile of her own. “Of course, my darling Robin-chwan!!<3” he said, confidence returning to him. “That's good to hear!” she said happily, “But it would be wrong of me not to give you one more chance. Are you sure you are ready to do anything and everything I tell you, and be my slave to break however I choose? Be sure, this is your last chance. I can be very sadistic.” Her serious tone shift made the hair on the back of Sanji’s neck stand up for some reason. “What would you do if I say yes and change my mind later?” he asked, curious to see if there was a limit. “Slaves don't get to change their minds.” She said in the same happy, yet darkly serious tone. After a moment's pause, Sanji declared, “I'm all yours, my Robin-chwan!<3” “Wonderful!” she replied. “But for this week, and all future private interactions, you will refer to me as 'Mistress Robin,' 'Mistress,' or 'Goddess.' Is that clear?” “Yes Mistress Robin<3” “Very good. I have this whole week planned out for us, I only hope that the castle has the proper facilities we need,” she said in a satisfied voice. Sanji sighed with happiness. He was going to have a private week with his super kinky and unbelievably sexy 'Mistress Robin.' “Well,” she giggled slightly, “let's get started.”
