Lucy took her time getting dressed after her shower. It wasn't that she didn't want to go to the guild, she just enjoyed sleeping in and being lazy around the house. The team had just gotten back from a mission yesterday, and she was looking forward to relaxing and recharging before the next one.

Natsu already went to the guild early that morning. He tried dragging her out of bed, but she wasn't having it, telling him to go on without her. She won the battle, but she knew she should eventually go see her friends. Besides, as long as she didn't do anything strenuous, she would be fine.

Her lower thigh was still sporting a bruise from a fall she took two days ago when an enemy knocked her down, but she didn't let that bother her. The look on the guy's face when she blasted him with a chest full of arrows was enough to make her feel okay about her little slip up.

As Lucy headed towards the door, she paused, something on the couch catching her attention. She turned, seeing Natsu's scarf was lying on one of the armrests.

"He never forgets his scarf," Lucy mumbled, walking over to grab it.

She didn't hesitate to bring it to her nose, inhaling the warm scent of her boyfriend. A comforting feeling seeped into her body, her lips curving into a smile as she pulled it away to unfold it.

Just before she put it around her neck, an idea struck her. Her smile turned into a small smirk as she set the scarf down, heading to the bedroom. She kneeled beside the bed, pulling out a storage container that held their toys. Using the combination, Lucy unlocked it, removing the lid so she could peek inside.

Her heart picked up its pace as she grabbed something, hearing the familiar clanking sound as she brought it to her lap. It had been a while since they last used it, but just seeing it got her excited, her anticipation growing.

She spent a few minutes setting up the bedroom, hoping Natsu would be willing and Happy would be busy today. There was no bigger turn off than having the blue exceed walk in while they were doing the deed.

When Lucy was satisfied with how the room looked, she pushed the storage container back under the bed. She headed out the door, but not before wrapping Natsu's scarf around her neck, hiding her surprise beneath the scaly material.

Lucy wasn't surprised when she found Natsu in the middle of a competition. Him, along with a few other guys and girls, were on the guild's floor. They were all doing push ups while Erza stood over them.

"Two minutes left!"

Lucy made her way over to Levy, taking a moment to smile at her baby bump before greeting her friend.

"Who's winning?" Lucy asked after the two women shared a hug.

"I'm not sure," Levy said honestly, suppressing a giggle. "I haven't been keeping track."

Lucy was about to ask who started the competition, but stopped when she saw Levy's eyes widen as her hand rested on her belly. "What's up?"

"One of them kicked," she said, grabbing Lucy's hand to place it where her hand had just been. They waited a moment, but Lucy felt nothing. "Darn, I thought he'd do it again."

"How do you know it's a boy?" Lucy asked, causing Levy to shrug.

"Just a hunch. I'm hoping for one of each."

Lucy nodded, not needing an explanation. She wasn't ready to have kids herself, but when she was, she hoped she could have at least a boy and a girl. The possibility of that was high considering Natsu already told Lucy he wanted a big family, and she couldn't help but agree.

Lucy's eyes flitted down to the floor, finding her boyfriend easily. It wasn't his wild pink hair that caught her attention. Instead it was the loose black tank top hanging from his body. It went well with his tanned skin, showing off all the right places.

Her eyes roamed his body, admiring the taut muscles in his back and shoulders that flexed when he moved. She looked at his strong arms, her breathing picking up as her thighs pressed together. She thought about the many times he held her up with his arms alone. Whether it was to grab her during a battle or to hoist her up and pin her to the wall, Lucy loved being in his grasp.

She didn't try to stop herself from looking a bit south, her teeth catching her bottom lip as she looked at his firm ass. The jeans he was wearing did him justice, showing off his well-sculpted physique. Years of fighting and training definitely paid off. Not only was he one of Fairy Tail's strongest mages, but he was the hottest -in Lucy's opinion.

In her eyes, no one could compare.

Lucy smiled at his outfit of choice. He used to go around in a vest and white shorts. Then for a while he was wearing the one-sleeved coat. Over time he changed his style again. When he was battling he still wore those older clothes, but when he had the day off, he could be found wearing jeans and a shirt, or in this case, a tank top.

Lucy didn't mind at all, loving everything she saw.

Her hand came up to her neck to feel Natsu's scarf. She applied pressure, feeling the cold bite of metal against her sensitive skin. Her smile grew as her anticipation bubbled, excited about what might happen. Not only that, she was feeling aroused just from being in the guild while wearing such an item. Anyone could see it if the scarf slipped, making her heart beat that much faster.

She took a deep breath, knowing she couldn't get too excited. Otherwise Natsu -and possibly some other dragon slayers- might catch her change in scent.

A soft blush came to her cheeks when she looked back at Natsu's head, realizing he was tilting his face upwards so he could look at her. The look in his sharp green eyes told her she had been caught, but he didn't look upset. If anything he looked amused.

His head returned to normal once Erza announced there was only ten seconds left. Sweat dripped down his body as he kicked it into high gear, trying to get as many push ups as he could in those few seconds.

When Erza yelled for them to stop, everyone hit the ground. Natsu was panting, puffs of smoke leaving his mouth as he turned on his back. Lucy had no idea the competition had been going on for ten minutes until Levy whispered it to her. Why anyone would want to do push ups for ten minutes straight was beyond her.

Natsu recovered quickly, jumping to his feet at the same time Gray and Gajeel did. A crowd gathered around Erza, Bisca, and Lisanna, who were in charge of keeping track.

"First place goes to Gray," Bisca announced, causing everyone else in the crowd to groan. "Second place was Natsu."

"How many more did he get than me?" Natsu asked, narrowing his eyes at Gray's smirk. Lucy imagined he wanted to wipe that expression off his face, though she didn't know if it would involve violence or insults.

"Seven," Erza answered.

Natsu huffed, still glaring at Gray. "You only won 'cause I was distracted."

"What distracted you?" Gray asked, but his tone suggested he didn't care. He was too busy accepting the paper from Lisanna. "Thanks."

"Good luck," the girl said, but her voice was drowned out by Natsu's grunt.

"None of your business!"

"Such a sore loser," Gray chuckled, taking his paper to the bar to hand to Mira.

"Whatever," Natsu groused, but his attention was quickly shifting when he saw Lucy walk up to the bar as well.

Instead of sitting next to Gray, she sat a few chairs down. After Mira approved Gray to take the mission, he left, allowing her to head over to Lucy to help her. "Good morning. What would you like?"

"Lemonade, please. And good morning to you too." Lucy watched as Mira grabbed a cup and filled it. "What was that job for?"

"Oh," Mira started, bringing Lucy her lemonade. "That request came in this morning. Someone's offering one hundred thousand jewels for a simple security mission. Easy money."

"Is that why everyone was doing push ups?" Lucy asked, realizing what it was about. "They were competing to see who could get it?"

Lucy jolted when warm hands grabbed her waist, a pair of lips pressing against her bare shoulder. She didn't need to look, knowing the only man who would grab her like that would be Natsu. "I was tryin' to get that mission," Natsu mumbled against her skin, causing her to shudder as her heart flipped in her chest.

"Really?" Lucy was secretly glad Natsu lost then. Her plans wouldn't work if they went on a mission today.

"Yeah," he pouted, rubbing his nose against her skin before giving her shoulder a little nip.

Mira took that as her cue to leave, attending to another customer on the other side of the bar. Natsu waited until she was out of earshot before whispering directly in Lucy's ear, his warm breath fanning over her skin. "Why are you horny?"

Lucy swallowed thickly as she tried to compose herself. Just having Natsu so close while she was doing something so naughty was making her antsy. She had to stay in control if she wanted to keep from getting caught.

Feigning innocence, Lucy asked, "What are you talking about?" She was rather proud of herself for sounding normal, but Natsu wasn't going to be so easily fooled.

He breathed deeply, smiling to himself. "Don't play dumb. I can smell ya." His hands slid against her stomach as he wrapped his arms around her, pulling her backwards so she was flush against his broad chest. "What were you thinking about?"

"You," Lucy confessed, leaning into his touch. Deciding she didn't want to admit the real reason she got worked up in the first place, she went with the safer answer. "I like watching you exercise."

Natsu let out a low growl, Lucy feeling his chest rumble against her back. "That so?" he whispered, pressing his lips to her shoulder again as the tips of his fingers dug into her shirt. "Maybe I should work out in front of you more often?"

"Maybe," she breathed, feeling herself getting lost in his presence. She had to remind herself that they were in public, otherwise she might truly lose herself and do something embarrassing.

"Get a room," Macao grunted as he walked past them, heading to the bar to get another refill.

Natsu didn't say anything to him, but he did pull back some before letting Lucy go. He grabbed a bar stool, placing it next to Lucy before sitting down. "So how'd you sleep?"

"Good. You?"

"Awesome," Natsu said with a grin. "I'm ready to take another mission if you wanna? Gray got the best one, but there was another one that looked pretty good. We could probably finish it in less than two days."

Lucy bit her lower lip, the action catching Natsu's attention. "Actually... I had something else in mind for today."

"Oh yeah?" he asked, leaning in. "What's that?"

Lucy took a sip of her drinking, giving her a moment to think and a way to quench her thirst. She slowly released the straw, trying to think of the safest way to tell Natsu she wanted him to do some kinky stuff with her without alerting the whole guild to her plan.

While she was deciding, Natsu was looking. His eyes widened when they fell to her neck, seeing his scarf. "Hey, you brought it. Thanks, Lu—"

He reached to grab the scarf, but Lucy quickly caught his hand. "Don't," she said, sounding a little panicked.

Natsu raised a brow as he pulled his hand back. "Huh?"

Lucy repeated the word, this time sounding more calm than before. "Don't... I need to wear it." She hoped by saying she needed to wear it as opposed to she wanted to wear it would be enough to get Natsu to back off.

His hand was already in his lap, but his curiosity was still piqued. "Are you okay?"

Lucy took a long sip from her drink before saying, "I'm fine." She looked down at his hand, her core clenching as she thought about his hands running all over her body, nothing off limits.

Natsu's nose twitched before his eyes fell downwards. He looked at the shirt she was wearing before his eyes returned to her face. "What're you thinking about?"

"Still you," she said, not bothering to cover that part up.

His brows furrowed, still confused because her behavior didn't match her scent. He leaned in, trying to breathe deeper. The smell of her arousal was already making his body react, his heart racing as his cock twitched to life. "Lucy, what's going on?"

Deciding she wanted to tease him, she brought a finger to her neck, tugging at the scarf. It accomplished two missions. Not only did it allow her to cool down for a moment, her state of mind making her unbearably hot, but it also allowed Natsu to see a glimpse of metal peeking out from the scarf.

Natsu's eyes went wide in an instant, his breath catching. "Is that...?" He couldn't finish his sentence, too stunned to speak.

After adjusting the scarf so it was covering her metal collar, she nodded, her voice sounding breathless as she said, "Yeah."

A new wave of her scent hit him when she rubbed her thighs together. He was about to jump up and scoop her in his arms, but Lucy held up a hand.

"After my drink."

He swore she took her time on purpose, his need to feel her growing hotter than he could imagine. As soon as she finished her drink, she was in his arms. He didn't hesitate to run out of the guild, causing a few people to shout at him for nearly knocking them over.

He didn't care. He had only one thing on his mind. Lucy didn't seem to mind either, too busy laughing as she wrapped her arms around his neck, letting him carry her to the forest.

As soon as Natsu brought Lucy into their bedroom, he saw what she did to the place. A few toys, a bottle of lube, and a long chain were setting on the edge of the bed. His grip tightened on her, a low growl resonating in his chest.

He stepped forward, tossing Lucy on the bed. She couldn't stop herself from giggling as he climbed on top of her, but her laughter was quickly silenced with a fierce kiss. Natsu wasn't trying to take things slow judging by the way he thrust his tongue into her mouth a second later.

She moaned, eyes sliding shut as his hands traveled over her arms, sides, and hips. He released her mouth, only to press his lips to the corner of her jaw as his hands moved upwards, purposely brushing over her breasts. "Take off your bra," Natsu growled, pleased when she didn't hesitate to follow his orders.

While Lucy worked to unclasp her bra, Natsu sat up, straddling her waist. He pulled his scarf off, revealing the metal collar. He had to press a hand to his crotch, adjusting his throbbing cock while he drank in the sight. If Lucy was wearing that, it meant she wanted to play his slave.

He had no problem with that, as long as each of them were careful.

Natsu leaned in, brushing his lips against the cool metal before moving his mouth to her ear. "You remember your words?"

Lucy nodded as she pulled one of the straps over her arms, doing the same with the other a second later. "Yellow if I want you to slow down or change something," she recited, tossing her bra across the room. "Red if I want you to stop."

"Good," Natsu breathed, giving her earlobe a nip before pulling back again. He ran his fingers over her stomach, feeling her leaning into his touch. He palmed her generous chest, already feeling her nipples straining against her shirt.

Natsu had many kinks and turn ons, one of which was Lucy without a bra on. He thumbed at her tight buds, loving the way she squirmed and moaned when he touched her.

He climbed off her, grabbing the long chain to bring towards her neck. He clipped it to her collar, giving her the softest tug to test her. Admittedly, Natsu was turned on by having Lucy chained up, but he knew it could easily get dangerous. It was why communication was key when dealing with this sort of play. One wrong move and he could end up hurting her, and that was the last thing he ever wanted to do.

Lucy gasped as she moved with the chain, her hands helping push herself off the bed. Natsu pulled lightly, silently urging her to sit up. Once she was still, he leaned in, his lips sealing against her breast.

A whimper escaped her parted lips when Natsu ran his tongue over her nipple, wetting her shirt in the process. She ran her fingers through his hair until he ordered her to stop, another whimper climbing up her throat when she was denied permission to touch him.

"Yes," she whispered, arching her back to push her breast closer to his hungry mouth. His other hand was roughly palming her neglected one. It felt good, but she desperately wished he would focus more on her nipples. They were extremely sensitive.

She mewled when he bit her on the top of her breast, making her press her thighs tighter together. He pulled away, green eyes dark as he asked, "Yes, what?"

"Yes, Master," she whispered, earning a kiss to the lips. She resisted the urge to smile against his lips, happy she could make him excited with such a simple phrase.

Natsu's mouth eventually left her own, but she couldn't complain. It was reattached to her breast a moment later, then once again moving south until he reached the waist band of her skirt.

She thought he was going to take it off, whether by burning or ripping, but he left the article on. Lucy gasped when the chain was being pulled again, this time leading her off the bed. "Come," was the only thing Natsu said, voice much deeper than before.

She obeyed without protest, standing on her feet before walking towards the wall. He pushed her against it before stepping closer. Natsu towered over her, gripping the chain until there was no slack. Lucy leaned her shoulders against the wall, pushing her breasts outwards so he could get a good look at her, her breasts slightly lower due to gravity.

His dark gaze sent shivers down her spine, the pounding in her heart only increasing when he rested his right arm against the wall, leaning closer until his forehead touched hers. "Are you ready?"

"Yes, Master," Lucy moaned, feeling a bead of sweat roll down her face. She didn't know if it was from Natsu's heat or her own body temperature, but she was burning up everywhere.

Natsu smirked, revealing his sharp teeth. She imagined him biting her in all the right places, her throat tightening as she tried to swallow. He looked almost dangerous, and that thrilled her. She knew he would never harm her, but that didn't stop the rush from flooding her body at his feral look.

Natsu was strong, powerful, and for the moment, she was completely at his mercy. She loved it. She loved him. Every fiber in her being trusted this man, knowing he would lay down his own life if it meant she got to live another day. He was her other half, her companion. He was her best friend, no matter what.

Slightly breaking character, Natsu leaned in, his lips brushing against her ear as he moaned, "Fuck, hearing you call me that gets me so fired up."

She barely suppressed a giggle, not wanting to ruin the mood. In a low, sultry voice, Lucy asked, "You like it when I call you Master?"

Natsu took a deep breath, steeling his nerves. Lucy was all kinds of sexy, and while she was in that collar, he was free to do anything he wanted to her.

Well, within reason. The safe words were there in case the scene became too intense for her. But as long as she was okay with it, he could do whatever he wanted to make them both feel pleasure, and admittedly, a little pain.

Natsu ripped himself away from the wall, loosening his grip on the chain so it slid through his hand. He guided Lucy to the center of the room, right under the hook attached to the ceiling.

Before he made another move, Natsu met her gaze. his eyes were serious, almost cold as he said, "If anything, and I mean anything feels wrong, tell me." He needed her to understand, to listen. "Tell me if it hurts your neck, even just a little."

Lucy nodded, letting him know she understood. Still, he nuzzled his face against the crook of her neck, feeling the metal against his skin. "Okay," he breathed, slowly pulling back before his mindset changed again.

"You understand me?"

"Yes, Master."

"Good."

Natsu lifted his hand and the chain, looping one of the links on the hook. He allowed two inches of slack, wanting her to be able to move her neck but not wanting her to move too much. His hand landed on her collarbone, sliding his fingers upwards until he touched her collar.

"How's that?"

"Feels good," Lucy whimpered, her big brown eyes batting at him.

Natsu pressed his thumb against her neck, careful of any spots that would harm her. He didn't have to ask, Lucy already knowing what he wanted to hear.

"Feels good, Master."

He smirked, his blood pumping hotter at the word. He was in charge of her right now, in complete control of the beautiful goddess before him.

Now that he was sure Lucy was okay, he kneeled down, his face level with her skirt. Natsu pressed his nose against the material, inhaling her delicious scent as his mouth started to water.

His callused hands traveled up her legs, pushing her skirt higher until his fingers felt her blue silk panties. Natsu felt his cock throb again. He loved when she wore such delicate underwear.

Natsu pulled them down, waiting patiently as she stepped out of them. He rose to his feet, not bothering to hold back his hungry gaze as he presented the panties to her. "Open."

Lucy parted her lips, allowing him to push her panties inside. She hummed at the flavor of herself, potent and fresh since she just showered not too long ago. Natsu took her by surprise, his hand slipping under her skirt to play with her bare flesh, feeling her soft folds that were wet with arousal.

Lucy bit down on her panties as she shuddered, trying to get closer to his teasing fingers. Before Natsu lowered himself again, he pulled out her panties, wanting her to be able to tell him if anything didn't feel right.

He hit his knees, pushing her shirt up before growling. "Hold it up."

She did as she was told, gasping when his tongue ran over her slit. She didn't expect him to get right to it. Usually he liked to tease her more, but she couldn't deny she was happy with his decision.

It wasn't long until Lucy was a moaning mess, her fingers digging into her skirt as she struggled to stay in control of herself. "Yes! M-Master! F-feels so go—ahhh! Please!"

Natsu felt her legs quiver when he inserted two fingers into her core. She was dripping, clear fluid running down her thighs and his hand. He kept his mouth sealed around her clit, mercilessly lapping and sucking at it while his fingers continued to thrust quickly into her.

He loved the feeling of his fingers fucking her, her body shaking as pleasure took over her senses. His free hand grabbed at her ass, feeling her firm backside before his hands slid down. He was mindful not to put too much pressure on the bruise on her thigh. He wasn't into that sort of pain play. He preferred spanking if he wanted to go that route.

Natsu knew when she came the first time, her inner walls gripping him tighter as she stumbled over her words. "Nat—ahhh! I mean Master, good! Feels so g-good! Nggh!" She was sobbing, her body writhing as he brought her to new heights.

She came around his fingers once more not a minute later, but instead of moaning those sweet words, Natsu heard something that alarmed him.

"Y-yellow!"

Natsu immediately stopped touching her and moved back. He thought she was using the safe word because she didn't want him doing something to her, but once he looked up at her face, he found out that wasn't the case.

"Shit," he muttered as he rose to his feet, not hesitating to grab her, lifting her up to settle her around his waist.

Her legs weakly gripped him as she panted. "Thank you."

Natsu wanted to growl, somewhat angry at her for not using the safe word sooner. Her neck was red from where the metal collar had been rubbing at her. He didn't need to ask her what happened. He saw enough to figure it out on his own.

Lucy's knees had gone weak while he was playing with her, causing her to lower herself. That left no slack in the chain, forcing it to tug at her throat. He wondered if it was just because of her orgasms that she got weak in the knees, or if it was because of their mission they finished yesterday.

Looking back on it, he realized he should have waited until he knew she was fully recovered before attempting this type of play. He mentally scowled himself for not asking if she had the energy to do this, assuming she did since she initiated the scene and consented to letting him string her up.

Natsu inspected her neck, then listened to her breathing. It was hard for him to tell if she was alright, seeing as she was panting. It could have been from lack of air or from her orgasm. He held her tighter, whispering in a concerned voice, "Are you okay, Lucy?"

She nodded, swallowing normally. It took her a second to catch her breath, her body still flooding with pleasure from Natsu's ministrations. "I'm okay, promise."

Natsu decided to take her at her word. Instead of lowering her to her feet, Natsu tightening his grip on her before lifting a hand, unhooking the chain from the ceiling. They could try this play another day, but for now Natsu didn't want to risk it.

Besides, that hook was used more for chaining up her arms, or sometimes even his arms when Lucy was feeling dominant. If only people knew what Lucy's kinks were. She didn't use her whip on him, but she did like to use a few toys to spank him when she deemed him 'naughty'.

Natsu brought her to the bed, gently setting her down. He kept the metal collar on, but he didn't hold onto the chain, letting it lay on the bed with her. A growl left his lips as he let his eyes wander over her body. He loved every curve and dip he saw, knowing how she felt beneath his fingers but never getting enough. She was his everything, and he wanted to make sure she knew it.

"Are you good with me continuing?" Natsu asked, setting his hands on her thighs. When she nodded, he spread them wide, flipping her skirt up so he could see her glistening pussy. "So pretty," he murmured, leaning in to swipe his tongue over it.

Lucy jolted, head falling backwards when Natsu's mouth enveloped her bundle of nerves. She moaned, urging him to do more. "Please, Master."

Natsu cursed under his breath before tasting her wetness, loving her unique flavor. He remembered the first time he ever had her on his tongue. No matter how much he sampled, she always tasted delicious to him, causing the fire in his belly to burn hotter.

He shifted back to her clit, spoiling the pulsing nub as he slipped two fingers inside her. Lucy was writhing beneath him in no time at all, her voice echoing through the room as she begged. "Please! Caaaahhh! C-Can I touch myself?"

Natsu felt his body course with pleasure at her request. "Yes."

He looked up, locking eyes with her as he devoured her pussy. Lucy pushed her shirt down, revealing her large breasts. He watched as she played with them, her fingers rubbing circles around the pink skin before pinching her nipples.

Natsu roughly sucked on her clit as he rubbed against her inner walls, searching until he found the spot that made her cry out.

"Yes! Na-Naahhh!"

He figured she was trying to moan his name. He wouldn't punish her for not calling him master. Truthfully, as much as he loved hearing her call him that, he enjoyed his real name more. The only reason he preferred her calling him Master during this type of play was to set the mood right. Plus, it was pretty thrilling.

When Lucy came again, Natsu slowly continued licking her. His fingers massaged at her walls as they contracted, squeezing the digits as if trying to milk them. He wanted to draw out her pleasure, waiting until she was down from her high before removing himself from her body.

Natsu climbed off the bed, taking off his shoes and socks before fumbling with his jeans. He hated them at first, thinking they were too constricting, but he was used to them now. Still, they were a lot harder to take off than his white shorts, making him frustrated when they wouldn't just come off with a few yanks.

With his pants finally undone, Natsu pushed them and his boxers down, letting the cool air touch his cock. A bead of pre-cum formed at the tip, but it was quickly ruined when Natsu started stroking himself, causing more pre-cum to leak out.

He didn't bother telling Lucy to suck his cock. He wanted her now, not able to wait another minute. His only regret was he didn't get to play with the toys she set out, but he could always use them next time. Right now, he needed to feel her around him.

Lucy was already sitting up, her eyes a little hazy, but the smile on her face let him know she was doing good. The chain clanked as she shifted, batting her beautiful eyes as she asked, "How do you want me, Master?"

Natsu growled, fingers twitching with excitement. He looked down at the bed, already knowing which position he desired. "Lay at the edge."

Lucy obeyed, scooting until her ass was halfway off the bed. She shamelessly spread her legs for him, shifting her back so her breasts stuck out more than normal. She smiled, knowing how to get his blood pumping as she stuck the tip of her finger in her mouth. "Please," she whispered, voice just as seductive as her plump lips. "Fuck me?"

Natsu didn't have to be told twice.

He rubbed the underside of his cock against her folds, collecting her wetness to lubricate himself. Lucy moaned when he ran over her clit, her hips lifting to chase his cock. He pulled back, causing her to pout as he moved to the bottle of lube on the bed. She was already warmed up, but there was nothing wrong with using a little extra help. He smeared it over his cock, returning to her exposed pussy a moment later.

Grabbing the chain, Natsu gave her a light tug. He wanted to feel in control again, but he was more cautious than before, terrified of harming her. His other hand wrapped around the base of his cock, lining himself up with her before pushing inward.

Natsu groaned as he felt her wet heat surrounding him, Lucy gasping as her hands went to his chest, feeling his muscles before slipping to his sides. He said nothing, loving the way her fingers felt against him.

He slid in inch by inch, filling and spreading her inner walls until he was fully inside her. Lucy purposely clenched, causing him to moan. He loved the feeling of her squeezing him, massaging him with her body.

"Amazing," he mumbled, eyes dark with lust. As if she didn't hear him, Natsu said, "You're amazing."

Lucy smiled, giving Natsu's sides a tug to silently tell him what she wanted. He decided he didn't care if he was no longer the one 'calling the shots'. He wanted to be close to Lucy, so he leaned in, pressing his lips to hers to share a sweet kiss.

"I love you," Natsu breathed against her lips as he started to pull out, earning a gasp from both of them when he slammed his hips into hers. "Fuck, you feel incredible."

"You do too," Lucy moaned, raking her nails against his tank top. She slipped her hands under the hem, pushing his shirt up so she could feel his firm back.

Natsu growled when he felt it, his hips moving again to give her another powerful thrust. "Harder," he murmured, already feeling the pressure building in his lower abdomen.

Lucy dug her nails into his back, leaving red welts when she scratched him. He grunted as he slid into her pussy again, loving the pleasurable pain that coursed through him. He picked up his speed, moaning with every thrust while Lucy did the same.

"F-fuck! L-love it!" Lucy whimpered, throwing her head back when Natsu let go of the chain in favor of rubbing her clit.

He watched as she squirmed, her body fighting to accept and decline the pleasure. Her thighs shook, her bangs matted against her forehead from sweat, and a beautiful flush coated her cheeks, neck, and the top of her chest.

"Damn! I love having you wrapped around me!" Natsu leaned in further, changing the angle of his thrusts to earn a choked sob from his girlfriend.

"Ahhhh! Y-yes! Right there!"

Natsu continued snapping his hips, Lucy's chanting spurring him on. Feeling a bit cocky, he sunk his teeth into one of her breasts, feeling the soft flesh give beneath his teeth. Lucy cried out, her nails threatening to break his skin as she scratched him harder, but he loved the feeling.

Lucy's core started clenching around him, preparing itself for another orgasm. He growled, smirking when he saw her shudder at the sound. "Does that feel good?"

"Yes Master!" she screamed, Natsu thankful they were in the forest where no one could hear her and complain.

"Who's your master?" he asked, sweat dripping down his forehead and neck as he fucked her, feeling his endurance about to snap.

"You!" Lucy's body started shaking as she let the pleasure overwhelm her. "You are!"

"Who owns you?" Natsu growled in satisfaction when she didn't hesitate to answer.

"You do!"

"Damn," he grunted, knowing he was about to meet his end. "You're so fucking sexy! You belong to me, and only me!"

Lucy nodded, a trickle of drool dripping from the corner of her parted mouth as she moaned. "Yes!"

Natsu pushed her thighs further apart as he leaned in, growling into her ear. "You're mine! I love you, Lucy. Fuck, I love you so fucking much!"

His fingers that had been rubbing her clit started pinching and tugging, her walls clenching rapidly around his cock. He barely made it, feeling Lucy's orgasm hit just as he released, his cum filling her completely.

Natsu gave a few small thrusts into her, making sure she received everything he had to offer. Lucy was limp in his arms, her chest heaving as she struggled to catch her breath. He could relate, panting on top of her as his heart tried to regulate itself.

"Damn," he mumbled against her shoulder, his head resting in the crook of her neck. "That was awesome."

Lucy let out a breathy sigh as she nodded. "Yeah."

"How's your neck?" Natsu asked a few second later, slowly peeling himself off her. While she spoke, he removed the chain and unclipped the collar, revealing more red skin.

"Better. I stopped when it felt bad, so it didn't hurt much." She smiled, cupping his cheek as her thumb brushed against his skin. "Thank you for taking care of me."

Natsu nodded, lifting himself off her while slowly pulling out. He saw some of his cum leaking out of her core, dripping on the sheets. "I'll do anything for you," he promised.

"I know."

Lucy removed the metal collar, setting it to the side before rubbing at her neck. She saw him open his mouth, but she was already shaking his head. "You don't have to apologize for saying I belong to you."

Natsu closed his mouth, blinking in surprise. "How'd you know I was gonna say that?"

"You say it every time," Lucy reminded him, causing a faint blush to appear on his cheeks.

"I do?" he asked, giving her a sheepish grin. "Sorry. Can't help it." He didn't want Lucy to think she was actually his property. It was only something he said in the heat of the moment.

"You're fine," she said, moving on the bed so she was in the middle. She stretched out her arms, wanting to cuddle.

Natsu welcomed the feel of Lucy's arms around him. His mind was a bit foggy and his back was sore, but he was happy despite it all.

"Want to know a secret?" Lucy asked.

Nodding, he said, "Absolutely." After dating for years, he knew most of Lucy's secrets, but he was always eager to hear more.

In a whisper, Lucy admitted, "I really like when you call me yours."

Natsu slung an arm around her waist, pulling her closer to him. "Yeah?"

"Yeah."

He hummed, tucking his head against her shoulder. "Well, I like when you call me yours too."

Lucy smiled, turning her head so she could press a kiss to Natsu's clammy forehead. They both needed showers, but that could wait. Lucy wanted a nap, and judging from the yawn that escaped her boyfriend, he did too.

"Maybe we can take a mission tomorrow?" Natsu asked, tangling his legs with hers.

Lucy nodded, her eyes closing as she let sleep take her. "Sounds good."

Less than a minute passed before Natsu heard her even breathing, letting him know she fell asleep. It took him a few more minutes to follow her, his mind racing as he thought about what he would need to do to go on a mission tomorrow. They would need to clean the bedroom first, then pack a bag. Lucy would probably have to wear his scarf if those marks on her neck turned into bruises, but he didn't mind that one bit.

He loved when she wore his scarf, his possessive side feeling satisfied when she wore his clothes. He just hoped she wasn't in any pain when she woke up. If so, they would have to discretely ask Wendy to heal her.

"Love you," he murmured, feeling his consciousness fading. Today was unexpected, but still welcomed. He enjoyed when it was Lucy who initiated sex, especially when it was of a more kinkier variety.

Natsu knew he couldn't expect it all the time, so he savored it while it lasted. He would need to be more careful in the future though. Today had been too scary, even if Lucy used her safe word as soon as she felt uncomfortable. When he was in the dominant role, he needed to be more alert to her needs.

They weren't perfect at this, but they were learning. As long as they were safe and having fun, things would work out. He was confident they would get better with practice.

His lips curved into a smile just as he fell asleep. The idea of practicing didn't sound bad at all.

And who knew? Maybe Natsu would even let Lucy put the collar on him for a change.

So what'd you think? I had a lot of people ask me to write something for the picture, so I decided to give it a shot. Let me know what you thought of this one-shot! :) Was it kinky enough?

Anyone want a part two where Lucy chains Natsu up? I wrote a sequel for this chapter in this collection. It's chapter 11: Dungeon. :P
