Warnings: BDSM, Consensual Non-Consent

Luffy had only ever asked for everything, Nami mused. He did not meet halfway, nor did he relent to less than what he wanted.

Which meant that when he had asked for spreader bars, gags, cuffs, and nipple weights, Nami had supplied even knowing that they were for her and not him. She could imagine the scene already. Nami trussed up for him on his bed while he unwrapped her and had his way.

It was his birthday after all.

She ignored the fact that it excited her. He was such a selfish captain to demand this sort of thing from her after all. It was just for him anyway.

Nami wasn't looking forward to being tied down and spread open for him after all. Her heart wasn't beating so fast that it distracted her. Actually, wasn't it a bit expected at this point? She wondered if they needed to talk about some new activities; she ignored the new toys all set in a row on the bed.

When someone knocked on the door, she threw the blanket over them.

"Coming!"

Luffy grinned at her from the other side, leaning against the doorframe while his eyes twinkled. Men weren't supposed to look so good in leather. Her eyes darted up and down his muscled frame in the jacket Robin had gifted him. Nami hadn't suggested it for him, but Robin had smiled at how red Nami had been when they saw it on the rack.

She licked her lips. "Luffy, hey."

"Shishi! You ready yet?" He tried to glance around her into the room, but she huffed.

"Not yet! Besides, you haven't-" Nami halted and glanced behind him at the deck before she yanked him inside.

He laughed. "Ooh, you're excited, aren't ya?"

Nami stamped aside the hot flash that threatened to rip through her. "It's not that. You just haven't told me what you want me to do with all this. I - I mean, I can imagine, but-"

When he grinned broadly, she cut herself off and stared as his tongue slipped over his lips.

"Let's disembark first."

As she had suspected, Luffy wanted her to wear the new toys. In the cabin they had rented out in the middle of the island, Nami endured his tongue while he slid her clothes off. He tossed them aside like so much trash. She was his in this scene. To do with as he willed until she could stand no more. Until his fun began.

He had told her to try to deny him.

His mouth suctioned onto her breast with a growl she had never heard. Standing nude before him, Nami panted with barely concealed lust for his tongue on her nipples. She couldn't imagine attempting to ignore him though. When something cold clamped onto the other teat, she glanced down to see the clamp weighted with a chain. The chain ended with another clamp which he fastened to her other nipple while he pinched it and grinned.

Nami couldn't stop the moan until he yanked on the chain, and she yelped instead.

"No!"

Luffy pulled again with a groan, and she clenched her teeth shut. "That's better."

Slipping behind her, Luffy grasped her hips and dragged his nails to her sides as she writhed to his touch. When she tried to pull his hands off, he laughed before he took hold of her wrists with little problem. Luffy yanked her arms behind her back to cuff her. She shuddered from the rough treatment before he slapped her ass with a pleased sigh.

"Please, please, no," she whispered even as she resisted spreading her legs. The restraint to keep herself from bending over for him was more intense than she had anticipated.

Resist Luffy? How?

Nami yelped when his hand landed again, but his fingers began to dig into her. "Ah! You bastard!"

Her heart quickened. Luffy groaned and withdrew his fingers.

"You'll pay for that."

She paled when she heard the gag clink - an O-ring gag which he forced into her mouth. Nami whimpered, but didn't fight it too much, flinching from the idea of her teeth and gums hurting of all things. Now she panted through a wide-open mouth, and Luffy licked up her throat.

Then, Luffy placed a heavy set of keys that jangled into one of her hands. With a burning face, she squeezed them. If she dropped the keys, it would all be over. They could talk again and ensure that she was all right before they either continued or stopped altogether. Nami tried to lick her parted dry lips.

He leaned in from behind to whisper into her ear, "Try to give me a good fuck, whore."

When his hand struck again, her breasts shook, and she clenched her teeth when the weight of the chain pulled on her nipples more. He thrust his fingers back inside. His breath hit the back of her neck as Nami's heart pounded away. She whimpered, and he still held her back, a hand clenched on her cuffed wrists while he stroked deep inside.

Attempting to pull away, Nami gasped when he pulled his fingers out to spank her again.

"The hell do you think you're doing!? Are you trying to get away from me?"

Nami squeaked through the strikes, but she tried to yank out of his grasp only to stumble when she broke free. She glanced back once, and the grin that greeted her made her run for the open cabin door with a shudder.

Naked, shaking with excitement, Nami ran outside into the forest.

The chain pulled on her sensitive teats even while the cold made them prickle into hardness. Nami shook on her legs and hesitated on the edge of the wilderness. Her breath misted before her from her open mouth.

Nami dared to glance back again, surprised to see that Luffy hadn't followed her yet until she saw the light move as his shadow arched out the door. His back turned to her, Luffy hummed something, and his fingers danced over the spreader bar he had elected to bring - a wooden bar fashioned with metal cuffs on the end.

He slapped it onto his palm.

Her heart leaped into her throat, and Nami ran.

The first bush she jumped through didn't scratch her legs, but Nami tried to avoid running through anything that looked sharp.

She tried to run anyway.

With how her breasts jostled with the heavy chain pulled on her nipples, her stride broke now and again with a hot flush. Her body pulsed in heat in the cool night air.

Luffy would hunt her down. And she had only nodded in numb agreement.

A hunt through the forest. She was running from her master who would come after her. Nami shuddered and ran faster.

When she thought she had gained some distance, Nami leaned her back against a tree and panted as her eyelids fluttered. She arched her back to her aching nipples before she could stop herself, but she did manage not to whimper.

She heard it first. A strange rushing sound soon enveloped the forest.

Hot rain splashed her cheek, and Nami swallowed nothing and moaned in frustration.

"Ah, there you are."

Squeaking, she lunged away from the tree and ran. If she stopped to look, she didn't know if she could escape him in time.

"You can't get away, you little whore."

Nami ducked around a tree, squeezing the keys in her hand to remind herself even as her heart threatened to explode from her chest.

Her knees shook while she tried to find a path away from him.

Luffy's laughter followed her.

Lust filled her. She wanted nothing else but to find a tree to press against so he could claim her like a beast. He was hunting her for her pussy and wanted nothing else but to-

For one terrifying instant then, Nami was weightless. She gasped as her foot slipped in newly formed mud, and she hit her side before she rolled into the wet grass.

The keys flew away from her grasp then, and she whimpered in frustration.

"Nami?"

Panting, she took account of herself, wiggling toes and fingers and then even elbows and knees, but she was fairly certain nothing had broken.

So he found her trying to roll over to the keys in an attempt to grab them on her own.

Luffy crouched over her with a pout before he smiled and turned her onto her side to help her. He found the keys to jiggle them and placed them back into her grasp.

Nami huffed with a pout that didn't quite work around the O-ring, but she tightened her grip on the keys. He still waited though, his eyelids lowering, and his hands began to stroke up and down her now wet, muddied body while he waited for her to drop them.

Cheeks forever stained red, Nami nodded to him, but he continued to eye her form.

He stroked her cheek. "You okay?"

She nodded again with a squirm under him.

When he rolled her onto her back, she whimpered open-mouthed, and he leaned over her.

"Little whore, if you really didn't want to get fucked, you wouldn't have fallen, would you?"

Grasping her hair, Luffy pulled on the chain, and her entire body jolted in pleasure. Her nipples screamed with her, and her head flopped back while she arched to him.

"See? You wouldn't scream unless you wanted it, whore." Still, he pulled, and Nami choked on a moan.

Luffy settled between her thighs, and she was ashamed that she was so weak to him, that her legs had been spread wide open for him already. Tongue lolling out, she tried to string any coherent thoughts together while he tortured her nipples with each tug.

"Your slutty body is made for this. You can't run from it anymore."

His smirking face filled her vision in the night, shielding her from the warm rain.

"I own you."

Nami blinked away tears and moaned when he hooked the spreader bar - which he had held in his sash - through the chain. When he tugged on the bar, her toes curled as it pulled her nipples. She whimpered, but her legs splayed wider, and she cursed herself. Luffy chuckled and bound her knees to the spreader bar while it remained looped in the chain.

Her eyes widened in shock as he released the bar and her legs. She kept her knees close to her chest, breath puffing in the cooler air. The bar no longer pulled on her teats, but Luffy just smirked at the sight of her bared to him.

"It's time to punish you for running, whore."

His tongue dragged across his lips before he slapped her muddy thigh. When her body jolted, the spreader bar between her knees tugged on the chain, causing a looping effect of moans yanked from her throat. With her yelp, he groaned. Nami's heart leaped again.

Sharp cracks landed on her ass, and his hand didn't stop. The rain pelting her skin somehow made every impact on her cheeks that much keener. Warm mud and rain cooling on her skin gave a distinct stinging sensation across her cheeks.

Nami sobbed wordlessly through the O-ring. Every time she thought she had a hold on not pulling her nipples, his hand would quicken or pelt her harder.

When he stopped, Nami squealed and writhed until he grabbed her hips. Her breath hitched as something pressed against her sopping entrance. Sometime during the spanking, Luffy had opened his jeans.

"I think I want one more thing for my birthday, slut."

Heart pounding, she hissed as Luffy sank into her to his hilt. His hot tongue laced around her parted lips, and she attempted to thrust her tongue against his.

He chuckled and thrust his tongue against hers with a groan before he bit her lip.

Luffy whispered, "Give me a bastard."

Nami sobbed when he began to rock into her. Luffy pulled on the chain himself, pressing her into the muddy grass. The earth mashed under her, making the perfect mold of her body bent in half for him. She twitched around him while her thoughts rang with those words.

The idiot was always so selfish!

He struck deeper, and Nami's hips rolled to meet him with a cry. Luffy curled over her, and she felt a heated rush of desire inside as she stared at him. His abs and hips worked her frothing hole. Tears formed in her eyes, and she tried to look elsewhere, but that meant his thick, scarred chest, chiseled to perfection. Worst of all was that he still wore that leather jacket!

Nami somehow tore her eyes from that masterpiece only to moan when his dark eyes held her still.

Luffy licked her lips. "I'm gonna knock you up, little whore."

She blinked her tears away and met his tongue with hers, breathing harder.

Her body writhed under him, and she warmed to his harsh words and how he pulled insistently on already sore teats. Nami twitched to the thought of his babe in her, how it might grow against his abs.

His thrusting, gyrating abs pressed into the back of her thighs, and she squealed as he ground her into the mud and grass.

With that confident grin of his, Nami realized he knew. He could always read her. She sobbed and tried to shake her head, but her hips tried to roll against his rocking hips. Her grip tightened on the keys, not daring to drop them.

How did one resist Monkey D. Luffy when he wanted something?

He chuckled against her lips, and Nami drowned in the muddy grass beneath him, feet kicking uselessly above him as her end swept all thought and senses away. As his abs tightened and he slammed into her one last time, she could have sworn that her womb fluttered in anticipation.

If he missed this time, Nami knew what she would ask for her birthday.
