Rated M for smut.

Summary: Restraining Natsu to a chair and cutting off his magic, Lucy interrogates him for information the best way she knows how.

Tied Up and Horny

Lucy gave a pleasant sigh, stepping out of the shower and wrapping a towel around herself. Wiping some of the steam off her mirror, the girl smiled at herself. It was something that she always did after a shower in a way to boost confidence, and a long, steamy shower was just what she needed after their last job.

Lucy and the rest of her team were sent to Oak Town to find out who was starting fires all over the place. The culprit always managed to flee the crime without leaving a speck of a clue behind, which meant they had to do some hard interrogating once they narrowed the suspects down. After fighting a group of bandits and troublemakers, they took them back to an investigation room, chained them up with restraints that cut off their magic, and let Erza handle the rest. It only took a couple of minutes for the red headed demon to wrangle the truth out of the arsonist. But after all of the fighting, Lucy had worked up quite a sweat, which was why she indulged herself in a nearly hour-long shower.

The girl stepped out of the bathroom, a bellow of steam following behind. There was nothing better than a cup of cold milk after a hot shower. Making her way into the kitchen, she went to open the fridge when a pair of warm hands squeezed her thighs and pulled her against something firm.

Lucy squealed, glancing over her shoulder to find Natsu giving her a shit-eating grin. He had pulled her back against him.

"Hey, Lucy," he said, his eyes glazing over her. His eyes zeroed in on a drop of water rolling down her neck. His tongue darted out, licking his lips.

"Natsu!" Lucy cried, very aware of the hard feeling prodding her bum. "What are you doing here? Don't sneak up on me like that!"

The boy cackled, finally releasing his hold on her. "Happy wanted to flirt with Charle, so I came here to check up on you. You've been in the shower forever!"

"It was only a couple minutes."

"In what world was that a couple minutes?"

Lucy waved him off, continuing her pursuit for a glass of milk. Opening the fridge, she buzzed in excitement, searching for the jug.

Only to find that it was missing.

"What happened to all the milk? There was a full jug just yesterday!" she whined, planting her hands on her hips.

Natsu tensed, feigning a grin as he shrugged. "I-I don't know. You must've drank it all!" If there was one thing he knew about Lucy, it was that she took her weird, post-shower traditions seriously. There was no way in hell he was going to let her find out that he drank all the milk because Gray bet him he couldn't finish the jug in less than a minute. Especially when he lost the bet.

Lucy arched a brow, turning to face her boyfriend. The sweat dripping down his forehead and his jittery demeanor gave it away. Something was up.

"I didn't drink it all," she said, narrowing her eyes at him. "You did!"

"Did not!"

"Did too! That's why you're acting funny! Admit it!"

"No way! You have no proof!"

Lucy glared at him. Her eyes darted towards the table where her keys rested. Natsu followed her gaze, a grin spread over his face.

"Oh? You wanna fight about it?" he asked. He lit his fists up in flames. "Sounds good to me! It's been a while since we sparred! I'm all fired up!"

Lucy snatched her keys. "I'm going to make you admit that you drank all the milk!" Placing a key to her chest, a light enveloped her body. As it died down, she was left adorning Capricorn's Star Dress.

Natsu's groin twitched in excitement as he glazed his eyes over her form, starting at the choker around her neck that went down to her ample breasts. They were practically spilling out of the small cups that were meant to cover them. His eyes followed the path of her dress, which delved between her legs and showed off a hefty amount of her creamy skin. The shades, the thigh-high boots, and the horns also stirred a hunger within him.

"Quit staring at me like that," Lucy said. She was all too familiar with that gleam in his eyes. It always made her weak in the legs and led to them clumsily making their way to the bed where he would bend her over and make her his. But not this time. This was a battle for justice!

Natsu's lips curled upwards into a smirk. "How about you come over here and make me?"

Lucy narrowed her eyes at him before lunging towards him. With Capricorn's Star Dress, her strength was only enhanced a little bit compared to Taurus' form. However, it did give her one drastic advantage…

Natsu found this form hot as hell. And she was going to make sure she used that to her advantage.

Natsu dodged every attack that came his way, also making sure to avoid any furniture. Her apartment wasn't the most ideal place for a sparring match, but hey, he wasn't one to care. Especially when he got to watch Lucy break a sweat.

He always loved watching Lucy fight. Watching her kicking ass and taking names, not to mention how fluid her movements were. It always made his stomach coil with excitement.

As Lucy threw a punch his way, Natsu caught her wrist with ease, leaning towards her and giving her a smug grin.

"Looks like I'm gonna win this round, Luce," he teased. His eyes darted towards her chest, where her breasts were deliciously pushed together thanks to the tight dress she wore. Oh how he wished to push his face between them and help himself.

Lucy bit back a smirk, watching as Natsu got distracted. That slipup was all she needed to gain the upper hand. Snatching her hand out of his grasp, she dropped to the floor and swept his legs out from under him.

Natsu yelped and landed on the floor with a loud thud. Before he could recover, Lucy skillfully cracked her whip and wrapped it around his arms. She tightened it, making sure that he couldn't escape. Well, he could always burn it off, but she knew he wouldn't do that to her favorite whip.

Especially since he loved when she used it in the bedroom.

Lucy glanced around the room, her eyes finding the object she was looking for on the table. Dragging Natsu to the chair by the table, she sat him on it. She grabbed the chains that they used on their last job- the ones that stripped away a person's magic- and chained his arms behind the chair and his ankles its legs. Once she was finished, she stepped away to admire her work.

Natsu sat grumpily in the chair, a pout resting on his face. He was never one for losing. But the battle wasn't over yet! He still hadn't admitted to drinking the rest of her milk, and he'd be damned if he gave in now just because of some lousy chains.

Lucy stood in front of him, planting her hands over her hips. She glared at him through her sunglasses.

"Care to tell me the truth now, Natsu?" she asked.

"I ain't tellin' you nothin'!" he shot back in defiance.

Lucy smirked at him, crossing her arms beneath her chest. Raising one leg, she propped it next to him on the chair, her Star Dress slipping between the gap between her legs and nearly giving Natsu a peek at her underwear.

"You sure about that?" she said.

Natsu swallowed thickly, his eyes staring at the area where her dress started to slip. His groin twitched in excitement, wishing that the dress would move some more and show him what kind of underwear the Star Dress came with.

Shaking his head, Natsu fortified himself and forced his gaze upwards to meet Lucy's.

"I didn't drink it," he lied, giving her a teasing grin.

Lucy's brows slanted in annoyance, but she recovered smoothly. "Oh yeah? We'll see how long you can keep that charade up."

Kneeling in front of him, Lucy brought her fingers to the hem of his pants. The corners of her lips twitched upwards into a coy grin as she felt Natsu tense under her touch and saw him gulp. That was just the reaction she was looking for.

Sliding his pants down his legs, she let them fall around his ankles in a heap. Eyeing the tent formed in his boxers, she licked her lips.

"Lucy, what do you think you're doing?" Natsu choked out. His groin was throbbing in excitement, and he wasn't sure how long he'd hold up. His confidence in winning was beginning to go down the drain.

"Oh, nothing," Lucy chirped in reply. She traced her fingers up his thighs and over the thin layer of his boxers. Every time she got close to his bulge, she changed directions to keep him wanting more. It was exhilarating to have the power. She was going to use all of it.

"Want to tell me what happened to the milk now?" Lucy asked, peeking up at him.

Natsu shook his head quickly. He wasn't going to lose! "No way!"

Lucy shrugged. "Okay."

She slid her hand over his bulge and freed his cock through the hole of his boxers. It sprung free, its length bringing a hungry gleam to her eyes. Tracing her finger over his shaft, she watched him shudder from her touch.

"What about now?"

"N-Never!"

Lucy wrapped her hands around his length, her fingers smoothing over its vein. She had always loved the velvety texture of his skin. She began to lightly pump up and down, keeping her grip loose to warm up.

Not wanting him to enjoy it too much- this was an interrogation, after all- Lucy stopped her movements, leaving him thirsty for more.

"Lucy," Natsu gritted out, his voice dark and low. "Let me out of these chains."

"Are you going to admit that you drank all the milk?"

"No!"

"Then nope," Lucy said with a shrug.

Her gaze fell back to his cock, her tongue poking out to wet her lips. Leaning over him on her knees, Lucy grabbed his shaft with her hand and pulled his cock closer to her. She pressed her lips against his shaft, leaving butterfly kisses.

She could feel Natsu shaking in his seat. It was driving him crazy.

Lucy's tongue darted out, sliding over his shaft. She could hear a soft groan slip past Natsu's lips as she worked her tongue on him. She kissed the tip before opening her mouth and sliding his length inside.

"Lucy!" Natsu shouted, shaking the chair. "Let me out already!"

Lucy ignored him, continuing with the task at hand. Tightening her mouth around his shaft, she bobbed her head up and down, stretching his sensitive skin with each movement. She moved slowly and didn't push his cock in too deep, knowing that he would burst if she did. She couldn't have that happening.

Natsu groaned, trying to thrust his hips so that he could go deeper within her mouth. She was toying with him. He knew that. And it was working.

"Lucy, this is your last chance-!"

She tugged on him hard before removing her mouth with a pop. Her lips curled into a victorious grin. "Or what? You're all chained up, Natsu. The ball's in my court."

Lucy was about to resume her oral ministrations when another thought came to mind. Leaning over him, she pressed his cock between her breasts and squeezed them together.

Natsu went still as a rock, watching as Lucy continued to massage her breasts around his dick. That had always been a fantasy of his, and it was exceeding his expectations by far. Just watching her large mounds moving against him was driving him wild.

A low growl resonated deep in his throat. His hands balled into tight fists behind him as Lucy brought him closer and closer to the edge of climax. His breaths were ragged, his toes curling from sheer ecstasy.

"You know," Lucy's voice called out to him. He tore his eyes away from the delicious sight of her pleasing him to meet her gaze. A mischievous grin rested on her face as she stopped her movements, leaving him on the brink of climax. "If you just admit what happened, I'll let you finish. And I'll let you finish however you want." As if trying to make her point clear, she squeezed his cock between her breasts once more.

"Lucy," he panted out, narrowing his eyes at her. "You're startin' a war that you don't wanna start."

Lucy angled her head to the side, propping her finger under his chin and lifting his gaze. "Oh, Natsu. Don't you know? It's not a war if its one-sided." She sighed, her eyes traveling towards his cock. "Guess we'll have to keep doing this the hard way."

Lucy was about to slide his cock between her breasts again when there was a sudden clink. In the blink of an eye, she was tackled back onto the floor as Natsu hovered over her and caged her between his arms and legs. He pinned her arms above her head. Her eyes were wide, mouth parted as she stared up at him.

"H-How did you escape!?" she asked, her voice shrill.

Natsu gave her a sly grin, leaning his face closer to hers. "C'mon, Luce. You really think a couple of chains are gonna keep me away from you? I don't need my magic to get out of those."

"Then why didn't you break out right away?"

"You kidding? I got to just sit back and watch you pleasure me, like hell I'm gonna pass that up."

"Why are you stopping now then?"

Natsu tightened his hold on her wrists, his eyes dropping down to her breasts. "I got tired of being the only one gettin' teased. It's time to return the favor."

Lucy opened her mouth to reply when Natsu crashed his lips against hers. Her eyes fluttered closed as she wrapped her legs around his torso, bringing him against her. His lips left hers, only to find purchase on her neck. He sucked on her flesh fervently, leaving red marks in his wake.

Natsu pulled away, a proud grin resting on his face as he studied the hickeys.

"Looks like you're gonna have to wear my scarf for a while," he said.

"I don't care," Lucy replied, her voice airy. Her arms snaked around his neck, bringing him down onto her again.

Natsu's cock slid over the thin fabric of her Star Dress. Rolling his hips against her, he bit his lip to keep from groaning. After being on the edge of climax for the past twenty minutes, it was getting hard to hold back.

Lucy raked her fingers over Natsu's back as she grinded against him. The warmth he provided was enough to make her gut coil instantly. Still, as great as that was, her back was starting to burn from the friction between her and the carpet.

"Why don't we take this to the bed," Lucy suggested. "And no more teasing. I want you in me now."

Natsu didn't need to be told twice. Sure, he wanted to get some payback after her teasing from earlier, but he also wanted to hear her screaming his name. He picked both of them up, his hands on her bum as he carried her towards the bed. He plopped onto the end of the bed, sitting her on his lap. His cock was firm within her folds, this time her dress out of the way. To his surprise, she wasn't wearing any underwear.

"The Star Dress doesn't come with underwear?" he asked.

"No. I don't usually use my Star Dress straight out the shower," she replied. "Now hurry up and put it in me because I have been waiting for this moment all day."

Natsu grinned at her impatience before grabbing her by the hips and lifting her up a bit so he could position himself. Slowly lowering her on him, he felt his shaft slide against her wet folds and into her entrance. He was about to thrust deeper in her when he remembered something.

"Oh yeah. I drank the milk by the way. Now come take your frustration out on me."
