Nico Robin put pen to paper and immediately discovered she was once again out of ink. She frowned.

The archaeologist spent a substantial amount of her free time writing. Notes, research, crossword puzzles… It was how she passed the days on voyages in the Thousand Sunny when she wasn’t simply reading or enjoying the antics of the other Straw Hat Pirates.

This particular antic, however, had gotten on her final nerve.

Robin was not the only person who needed ink on the ship. Franky made blueprints, Brook wrote music, Chopper took medical notes, Sanji made recipes, and Usopp needed someplace other than his head to store his crazy ideas. They needed an amount of ink that would surprise people who didn’t know them very well. Especially after the Eraser Incident rendered pencils a non-option.

Really, when you got down to it, Zoro and Luffy were the only people on the ship who didn’t frequently require a method of writing. There had been a time when Robin wasn’t entirely sure those two could read. They could, but she couldn’t recall seeing either of them write anything.

But for everyone who needed a pen, there was exactly one person on the crew with the courage to steal ink from Nico Robin. This was not the first time, but it would be the last.

The raven-haired woman’s frown became a dangerous smile.

Nami didn’t notice the shudder passing down her spine as she finished her nightly cartography session, finishing up the final details she’d been able to parse on Vine Island’s coastline. Their most recent island adventures had been downright boring. It was a nice change of pace. Luffy hadn’t punched anyone, Zoro hadn’t lost buckets of blood, and the crew hadn’t toppled any brutally oppressive regimes (overly grabby plant life notwithstanding).

The navigator sighed happily and leaned back to stretch out from head to toe, pushing her chair onto its back legs. Sitting down for long had been an absolute killer on her lower back.

A small part of Nami wondered what Sanji would do if he saw her like this, pushing her chest straight out into the air while it was contained in a tight bikini. She had cycled through her outfits and arrived back at the jeans, bikini, and heels she’d worn when the crew had reunited. The cook would probably faint straight away.

The thought faded in an instant, just as the navigator reached the apex of her stretch. That’s when it happened.

Strong finger’s wrapped tightly around Nami’s wrists, half a second before a different pair grasped her ankles. Nami’s eyes shot open and she saw a pair of arms growing from the ceiling and holding her own in place. She knew immediately that looking down would reveal a similar sight of arms growing from the floor. Both sets of limbs began tugging, pulling Nami’s body taut in the air, and her chair stumbling to the ground beneath her.

“Robin!” Nami cried out. “What are you do—mmmmph!”

A pair of hands was suddenly upon the orange-haired woman’s mouth, one applying its superhuman strength to keeping her lips together and muffling her speech, the other holding her jaw shut. Nami shook her head furiously, trying to shake them off to no avail. These new arms were growing out of her own body. With her arms pulled above her head, there was now to shake them loose.

Now Nami began struggling in earnest. She was in great shape, stronger than most humans. You had to be to sail the New World. But her strength was on the low end of the scale New World pirates. Robi’s Devil Fruit arms were stronger and had better leverage. As much as she struggled, Nami found herself pulled higher into the air. As much as she tried to kick free, the arms at her feet held fast. And as much as she tried to scream, the hands gagging her kept her quiet enough to not alert anyone.

What the hell was Robin doing?

Soon enough, Nami heard footsteps coming in her direction. Her struggles renewed. If it was Robin, she could demand answers. If it was anyone else, she could ask for help. Nami thrashed as best she could suspended in the air. She tried to twist her head to look at the door, but the hands keeping her mouth closed kept her head in place. So she tried to yell as the door slowly, agonizingly opened.

“Are you sure you want to make this much noise?” Robin asked. Nami could practically hear the smirk in her voice. “What if Sanji notices and comes barging in to see you like this?”

Robin’s steps and the noise of the door closing seemed louder when Nami stopped yelling. The thought of Sanji catching sight of her this vulnerable, this easy to fawn over, was more than enough to quiet her. But not to make her stop struggling completely. She continued to try kicking and wrenching her limbs free of her captor’s multi-armed grip.

“Do you know what I’m doing this, Nami?” came Robin’s whispered voice in Nami’s ear. The older woman’s hands settled on her hips, settling some of her struggles. Nami felt Robin’s breasts press ever so lightly on her back.

Heat came rushing to Nami’s face. The snarling sounds she made were as much about ignoring the blush she knew was there as it was about answering the question.

“Fufufu,” Robin laughed. “It’s because I feel you need a little more discipline in your life.”

Discipline? What the hell was that supposed to mean?! No one on this ship was more disciplined than Nami! She was easily the crew’s most sane member!

“You don’t like to hear that, do you Nami? I can feel you getting angry. Does the truth hurt?” Her hands—the normal ones—crept a higher up Nami’s sides. “Nevertheless, it is true. You’ve taken something that didn’t belong to you tonight. You’re not the only one on this ship who needs ink, you naughty little Cat Burglar.”

Nami blinked, then blanched. The ink? Robin knew about that? But… she’d been so careful! How did know?!

Robin’s hands climbed higher. They soon passed the straps of Nami’s bikini. Nami tried to protest, tried to explain that it wasn’t something she did often, just when she was really desperate and needed some to get some extra work done. She didn’t know how clear she was without the ability to speak clearly.

It became a moot point once Robin’s fingers reached the armpits. Her deft fingers flickered  over Nami’s skin. And just like that, Nami was thrashing and squealing harder than ever before. “MMMMMPH!!” The sensation of being tickled drove her energy to new heights as her body screamed to get away. It was no use. Robin’s generated limbs held Nami fast and kept her quiet while her real fingers worked like feathers over sensitive skin.

There were tears in Nami’s eyes when it finally stopped. She slumped in the air, panting into Robin’s hands.

“If this happens again, I’m going to give you a spanking instead. Do you understand?”

Too spent to protest, Nami could only nod.

“Good.” And then Robin was upon her again. But it wasn’t just on her armpits this time. Arms popped up. Nami could feel fingers gliding over her sides and her belly. On the ground, another set found the soles of her feet, still held as still as could be, and got to work.

“MMMMMMMMPPPPPHHH! MMM MMMMRRYYYY! MMM MMMMMRRRYYYY!!!! MMMMMMMMMMMPPPPHH!!!”

After an eternity of laughter and thrashing, it stopped. It finally came to an end. And when Nami once again slumped in her crewmate and captor’s arms, she felt herself lowered to the ground. Gently, Nami was placed on the ground.

But Robin wasn’t quite done. Hands still held Robin’s feet together. And another pair pulled her arms down and behind her back. Nami didn’t resist. She let Robin manipulate her limbs, and didn’t even flinch when she felt rope being wrapped around her wrists and ankles. Before long, they were tied tightly together. And then more rope came. Nami felt her knees being bound together. She opened her eyes and looked down to see a multitude of hands pulling more rope around her arms, pinning them to her chest.

“Feel free to wriggle around a bit,” Robin’s voice was commanding. Nami took it for an order. She pulled at her bonds, testing them out and quickly finding them very well applied, very tight. Getting out of them would be very doable, but it would take awhile.

“Is this really necessary?” Nami finally asked when she felt one last length of rope connect her wrists to her knees, securely hogtying her.

“I think it is,” Robin answered. “I know thievery is your thing, Nami. But it’s gotten a little out of control lately.”

“You could call it practice,” Nami was smiling, sheepish and teasing. For the first time, she looked up at her crewmate and saw Robin smirking at her.

“I don’t. It’s like I said, you need a bit more discipline in your life.”

“You really think I’m the first person you should be targeting on this ship about discipline? Really?”

Robin’s smirk took on an edge. Nami blinked, a little creeped out as Robin bent down closer to her. “What makes you think you’re the first?”

When Nami’s only answer was a wide-eyed stare, Robin stood back up. “One last touch and I’ll leave you to work on your escape.”

“One last tou—aaah!” Nami grunted as a cloth was shoved into her mouth. She instinctively tried to twist her head out of the way, but another hand popped up to hold it steady. Once the cloth was firmly inside, another one was wrapped around her head. The cleave gag was effective.

“There we go,” said Robin. “I’ll leave you to your struggles then. Do not steal my ink again, Cat Burglar.”

And then she and her army of hands were gone. Nami took a deep breath, resting on the ground. Long minutes passed before she began working on her escape. And it wasn’t until then that she noticed the little thrill in her heart. The sudden realization that she was enjoying herself left the navigator thunderstruck. Nami was having fun being tied up.

It took her a few minutes to process this.

When that was done, Nami wondered what she would steal from Robin next.
