Pleasing his Princess

Natsu's face burned as he stepped out of the bathroom, entering the bedroom he shared with his girlfriend. Lucy was sitting on the edge of the bed, wearing nothing but a short black skirt and pink lace bra. Her legs were crossed, so he couldn't see anything under her skirt, but he didn't have to see to know she wasn't wearing any panties.

How did he know this?

Because the panties she wore that day were currently on him, the tight silk material not letting him forget it was there.

He took a deep breath, feeling his chest flush as he walked towards her. She was wearing a coy smile, but he didn't believe the expression for a second. The devious glint in her brown eyes told him she was up to something. Either that, or he was being paranoid.

"I was thinking," Lucy started, the hairs on the back of his neck raising as she pulled out her phone. "Would you be okay if I took some pictures?"

'I knew it,' Natsu internally groaned. Lucy wasn't going to let him get off the hook that easily. Wearing Lucy's panties while they had sex wasn't enough. She wanted more.

Deep down, Natsu couldn't blame her. When he got her to dress up for his fantasies in the past, he always requested a picture or two. Most of the time she complied, so Natsu nodded his head, allowing her to open her camera app.

He trusted her with his body, heart, and soul. Why wouldn't he trust her with his pride as well?

Lucy opened her camera app before setting the phone on the edge of the bed, saving it for later. She beckoned him closer, her hands grasping his hips when he was within reach.

Natsu's skin tingled where she touched, her hands slipping under his shirt to feel his toned stomach. Her fingers dipped between each abdominal muscle, her breath catching when she found his pecs. Natsu knew Lucy appreciated his body. He kept in shape not only for himself, but for Lucy too.

Seeing her eyes get hazy when she touched or looked at him made all the trips to the gym worth it.

"Take this off," Lucy commanded, pulling her hands from his shirt before giving the hem a tug. "Please?"

The 'please' was unneeded. She was just being nice. It was Lucy's turn to call the shots tonight, and he would obey her every command. If the scene got too intense he had his handy safe words he could use, but Natsu doubted they would get used tonight.

Natsu tore his shirt off, letting it fall behind him. Lucy's eyes widened as she licked her lips, mesmerized by the sight in front of her. Her hands followed her gaze, fingers brushing against tan muscles.

"Damn," she murmured, her thighs squeezing tighter. "It should be illegal to look this good."

If Natsu wasn't too busy thinking about the way Lucy's panties rid up on his ass, he would have teased her about making lame pick up jokes. Instead, he settled for looking down at her, watching as she appreciated his body.

"You know what sounds good right now," Lucy started, her fingers trailing down.

Natsu's heart pounded when Lucy touched the waistband of his sweatpants, his breathing picking up as she toyed with the strings dangling over his cock. Despite the weirdness that came by wearing Lucy's panties, he was half-hard, the knowledge that her fantasy was coming true making his blood heat up. He loved pleasuring Lucy, whether it was physically or mentally.

"What sounds good?" he asked when she didn't finish her sentence, eager to please her.

Lucy tore her gaze away from his waistband to look up, her teeth gnawing on her bottom lip. Natsu resisted the urge to lean in and replace her teeth with his, loving the way she whimpered when he bit her. He almost asked what she wanted again, the anticipation driving him wild.

"Kiss me," was all Lucy said, Natsu's lips crashing against hers a second later. They both tumbled on the bed, Lucy's hands grabbing his biceps while he placed his elbows on either side of her head, keeping himself steady as he stole her breath away.

Lucy parted his lips with her tongue, Natsu not giving her a fight. He let her roam around his mouth for a moment before invading hers, sucking on her tongue before massaging it with his own, drawing out a few mewls from the vixen beneath him.

Natsu moaned into Lucy's mouth when she started rubbing over his crotch, not caring how her hand ended up down there. He bucked into her touch, craving far more than he was receiving.

Lucy moved to push Natsu off her, removing her bra before he could ask her what she was doing. They were kissing again as the article of clothing hit the floor, their passion growing as the air around them warmed.

"Lick me," Lucy ordered, grabbing a fist full of Natsu's hair to guide him to her aching breasts. He was happy to obey, his tongue running over the pert nipple before his lips sealed around it. "Good Dragon!"

Pride surged in Natsu as he lapped at her sensitive skin, Lucy arching her back to get closer to him. Her nails raked against his scalp as she whimpered, "Yes! Natsuu!" Natsu loved all of it, especially the way his name fell from her lips as she cried out in pleasure.

"B-bite me!" Lucy yelled, her other nails digging into his shoulder blade. Natsu's teeth nipped around her nipple to tease her. She let out what sounded like a mix between a growl and a moan, liking what he was doing but also wanting more.

Natsu gave her what she craved, teeth lightly biting her nipple. He didn't want to hurt her, thankful when she cried out, "Fuck!"

Natsu ran his tongue over her nipple while his other hand pinched her neglected one. Judging by the moans he elicited, she was enjoying her treatment. "Oh god! Like that!"

Natsu wondered if he could get her off with nipple stimulation alone. It wouldn't be the first time, but he preferred touching other places as well. Lucy's body was incredible, and he loved playing with every part of it.

Natsu's mouth released her nipple, earning a huff of frustration from his princess. He almost snickered, loving the pout that formed on her face before it was replaced with another gasp of pleasure, his other hand rolling her nipple between his fingers. "Can I pet you?" Natsu asked, a primal need to stroke her pussy taking over his thoughts.

When Lucy nodded, his hand went down, flipping her skirt up to reveal her glistening sex. He knew all of her wetness didn't come from his touches. Some of it came from her fantasy coming true, and that made him more aware of the constricting material pressing against his erection.

He was hard, throbbing for attention, but his cock went neglected. He wanted to pleasure Lucy, his fingers slipping through her wet folds to touch her entrance. He played with her for a moment, enjoying the way she squirmed from his ministrations.

"Don't tease me," Lucy warned, causing Natsu to chuckle to himself.

"Yes, Princess."

He curled a finger as he entered her, feeling her wet heat consuming him. Lucy's hand tightened its grip on his hair, pulling his head towards hers so she could kiss him. She moaned, chest vibrating as he pumped into her, adding a second finger when he wanted to spread her wider.

"You're so wet," Natsu taunted against her lips, only for her to silence him with a demanding kiss. Lucy thrust her tongue into Natsu's mouth and whimpered, the sound music to his ears. He was content with fingering her until she came, but Lucy had other plans. After five more delicious strokes inside her pussy, Lucy ended the kiss, her voice airy as she panted.

"Take off your pants."

Natsu jolted, realizing what was about to happen. He tried changing Lucy's mind by rubbing a particular spot inside her body, the one that always made her wetter, but she wasn't having any of it.

"Now," she demanded, tone leaving no room for debates.

Natsu reluctantly pulled out of her body, his fingers moving towards his mouth as his lips parted. Lucy shook her head, her eyes narrowing. "Only good dragons get treats."

Natsu's cock throbbed from Lucy's words, a pout forming on his face as he lowered his fingers. He wanted to taste her arousal, but he couldn't. He would have to earn that privilege.

Natsu stood up, eyes falling to Lucy's exposed core, the folds of her sex wet with lust and need. He bit back a groan as his thumbs hooked under the waistband of his sweatpants, hesitating before he pushed them down.

Air brushed against the exposed parts of his cock, a good three inches of himself poking out from the pink panties that caged him. His balls were much closer to his body than he preferred, giving him no room to feel comfortable. He was used to boxer briefs, not 'hipster' female panties.

Natsu was about to grab the underwear to pull them down too, but Lucy shook her head. He didn't need to be told, taking the hint. He pushed his sweatpants all the way down, awkwardly stepping out of them. The back of the panties tried riding up more, his cock twitching against the front of the material.

'This is so weird,' Natsu thought, but he couldn't deny the sense of excitement that flooded his veins as Lucy's hungry eyes raked over his form. She sat up, not bothering to fix her skirt so he could see her beautiful pussy.

She used one finger to coax him forward, his knees sinking into the bed so he could climb next to her. He didn't expect what came next, his face burning hotter when she told him to get on all fours.

As Natsu dropped down to his hands, Lucy got up, grabbing her phone in the process. She told him to stay still, taking a few pictures of his backside before she gently rubbed his balls through the panties, the sensation feeling odd yet okay. It wasn't enough to calm the dull ache in his cock, but it was a start.

Lucy stopped touching him so she could lay on the bed, her back pressed against the blanket as she looked up at him. "Sit up." Natsu did as he was told, the head of his cock leaking pre-cum. He wanted her to touch him badly, but he would wait until she was ready. Like she said, good dragons deserved treats.

With her right hand, she pressed record on her phone, bringing the camera up to capture the moment. He trusted the video would stay between the two of them, their bond stronger than anything in the world. There were no doubts in his mind that she would respect him and not tell anyone about the things they did behind closed doors, valuing their privacy.

Natsu sucked in a sharp breath when she started running her hand up and down the front of the panties, avoiding any exposed parts of his cock. He bit his lip, reminding himself to stay still for Lucy. She wanted to play with him, so he would let her have her fun.

Natsu shuddered when her hand gripped his cock, pushing the pink material down so she could pump more of his length. His eyes slid shut as she stroked him, her grip firm and wet from his dripping need.

"Damn," he moaned, his voice shaky as he adjusted to the sensations.

When Lucy's fingers brushed over the tip of his cock, Natsu hissed, head tilting back as pure pleasure washed over his body. His fingers twitched, wanting to touch Lucy back, but he didn't. He wanted Lucy to reward him for being good, which was exactly what she did a moment later.

Natsu's eyes shot open when her hand left his cock so she could grab one of his hands, guiding it between her legs. He didn't have to ask what she wanted, his fingers searching for her bundle of nerves to play with, lazily rubbing it before drawing small circles around the nub.

Lucy's hand returned to his cock, relief and pleasure taking over his mind. He barely registered her command, mind buzzing from her touches.

"Up and down only."

Natsu nodded, panting as he ran his fingers up and down her clit like she wanted. He loved when Lucy told him how to touch her, knowing he was doing exactly what she liked in that moment. He wanted to please her in any way he could, even if sometimes it led him down some weird paths.

But Lucy was weird, and that was one of the things he loved about her. He could tolerate a little weird, as long as it got her off and made her happy.

"Do you like this?" Lucy asked, giving his cock a squeeze before continuing.

"Fuck yes," he grunted, throbbing for more.

Her strokes were long and slow, really feeling every inch of his cock. She would occasionally fondle his balls through the panties or rub at his inner thighs, all of her touches making his head spin. He moaned when she tucked the front part of the panties under his balls, the material staying in place as she continued to pump him in her hand.

Before Natsu knew it, Lucy was putting the phone aside so she could lean up, her tongue lapping at his tip to collect his beaded pre-cum. Natsu roared, his hips bucking to chase her mouth as she backed away. An apology rested on the tip of his tongue, but he didn't get to utter it, choking when she took him in her mouth a second later.

Heat flooded Natsu's body, a spring coiling in his lower stomach. He groaned when Lucy took him deeper in her mouth, her tongue running along the underside while her lips sealed tightly around his length.

"F-fuck," Natsu moaned, throat growing dry as he started approaching his release. "L-Lucy! Gaahh, I-I'm not gonna l-last if you— Oh fucking hell!"

His teeth clenched as he tried to hold back, his body shaking as he resisted that pleasure he craved so deeply. "C-can I? Please?!" Natsu asked, his voice more of a groan than anything. "Can I come?!"

Lucy's mouth was ripped from his cock before he could find his end, his body screaming from his denied climax. He panted, pink bangs sticking to his forehead from sweat. He didn't realize he started sweating until a drip rolled down the back of his neck, forgotten when Lucy gave the tiniest lick to his tip.

"You want to come so soon?" Lucy asked before leaning in, giving the tip of his cock another lick. She batted her eyelashes up at him, feigning innocence.

Natsu knew better, her darker fantasies no secret to him. His voice was rough with lust as he grunted, not knowing what he wanted. He knew coming would feel amazing, but his princess hadn't gotten hers yet. It would be wrong of him to finish without taking care of her first. What kind of dragon would he be if he allowed something like that to happen?

"No," he managed to whisper despite his body begging him to say yes. Pride bloomed in his chest when Lucy smiled, her eyes bright.

"No, what?" Lucy teased, removing herself from his cock. He wanted to whine at the loss of contact, but that would only prolong his suffering.

Natsu shuddered in pleasure when her eyes turned sharp, waiting for an answer. "No, Princess. I don't want to come yet."

"Good dragon," she whispered, her tongue prodding at his slit, smearing his pre-cum around the head. She didn't use her hands to touch him, his cock twitching as she gave him small licks.

Natsu's heart warmed from the praise. He craved it, wanting to please her so she would do it again. He would go to the ends of the Earth for her and then some. She was his everything, and he was hers.

Lucy was sitting up a moment later, one hand pulling at his left side while the other pushed on his right, effectively making him lay on his back. Lucy got off the bed, unzipping her skirt so it could fall on the floor before climbing on top of him, facing away.

With her panties still hooked under his balls, she hovered over his hips, taking his warm cock in her hands before giving him a firm pump. His head fell back as his eyes squeezed shut, his lips parting as a moan slipped out.

"Do you want to be inside me?" Lucy asked, her fingers teasing his head.

Natsu nodded, voice turning raspy as he begged. "Please! Fuck! I want that so fucking bad!"

He could imagine Lucy smirking, his eyes refusing to open. He knew if he looked at her right now, he was sure to blow his load prematurely. However, he couldn't stop his eyes from shooting open when he felt the blunt end of his cock gliding against her dripping folds, her wet heat threatening to consume him with a single plunge.

It took everything in Natsu's power not to buck into her, knowing that was the fastest way to get Lucy off him. Being patient proved to be the best option, Lucy slowly sinking down on his member when she knew she had tamed him. Their moans mixed as she took him in, every inch of his thick cock sliding against her walls.

Lucy squeezed around him a few times on her way down, making his body surge with pleasure with every clench. He was already close to finishing, but he wanted to hold out long enough for her to get her own happy ending, so he stayed strong.

Natsu realized how difficult that would be once Lucy lifted herself up using her thighs and legs, her walls massaging him as she rode him at a slow pace. Natsu's hands came up, ready to grab her, but he stopped before he could touch her bare skin. "Pr-Princess," he moaned, voice cracking as his control slipped.

"What is it?" Lucy asked, humming when she impaled herself on his cock again, not bothering to speed up her motions. The pace she set was killing him, but he could hold out if it meant making her happy. At least, he hoped he could.

"Can I touch you? Please?" He didn't know what was off limits. Sometimes when Lucy was in the dominant role she didn't allow any touching on his part unless she told him otherwise, but sometimes she didn't mind when he got handsy. He figured it was better to be safe than sorry, wanting his princess happy with him.

Lucy arched her back as she tilted her head up, her long blonde hair brushing against his chest. She was pretending to think, he knew she was, and that just made his heart beat faster. He loved when she was in control.

People assumed he was always the dominant one since he had a fiery personality, but he enjoyed surrendering himself to her on occasion, letting her guide him and set the rules. Lucy was the only person he trusted that much, the only person he felt that comfortable with.

He could always safeword out if he felt the need to, but he rarely did. Lucy knew when to let up for the most part, judging his body language to tell when he was on the verge of feeling uncomfortable. It was the same for him when he was in control. He would read Lucy's body and eyes to see when things were going too far so he could pull it back.

Trust was crucial.

"Yes," Lucy gasped, her hands grabbing his to put them on her hips. She squeezed them, letting him know she wanted him to hold on tight. He didn't disappoint, his grip bruising as she started going faster, her walls dragging deliciously along his cock, pleasure coursing through both of them.

"Fuck!" Natsu grunted, head slamming back against the bed. He could feel his resolve crumbling, the desire to fill his princess's core with his essence increasing with every pump into her.

Lucy's hips rolled as she rode him, drawing out the pleasure. She leaned back, her hands resting against the bed as she squeezed around his cock, gaining every shred of attention he had left. "Touch me," she ordered, moaning when Natsu did just that.

One of his hands covered a breast, fingers kneading the pliable flesh while his palm teased her nipple. The other hand sought her clit, rubbing it mercilessly once he found it. Lucy's movements stuttered as her body shook, her pussy convulsing wildly around him. She felt warmer as she came, crying out his name when he pinched both her clit and nipple.

"Na-Natsuuu!"

Natsu was shocked when he didn't come inside her, his stamina better than he expected. He was ready to continue to fuck Lucy, but she had other plans, pulling off his body once she came down from her natural high.

Natsu couldn't stop himself from growling when she removed herself from his cock, her narrowed eyes directing at him the moment she turned around. He quieted down, not wanting to upset her. He was close to his release. He didn't want her to decide he could wait longer.

She smiled when he didn't make another noise aside from his labored breathing, but he couldn't be faulted for that. Lucy drove him insane with her touches, his blood feeling like liquid fire as it traveled through his body. Her hand wrapped around the base of his cock as she leaned down, taking most of him in her mouth.

Natsu moaned when she started lapping around his cock, then hissed when she bobbed her head up and down, lips dragging over his sensitive skin. He knew she could taste herself on his cock, part of him wanting to ask her if he could have a taste too, but he couldn't form the words. His mind turned foggy as she took his cock deeper into her mouth, his end rapidly approaching.

"Nggh! F-Fuck! Pr-Princess! I-I can't! I'm gonna—"

He spurted into her mouth, hot white ribbons shooting down her throat. Lucy pulled up immediately, grabbing the front part of her panties to pull it back up, stretching them so they covered the tip of his cock. Natsu shuddered when he released against the material, his cum smearing everywhere and drenching her panties.

"You look so sexy," Lucy praised, stroking his cock through her underwear. He moaned in response, hips giving soft bucks as he continued to come. "I'm not even mad you came without permission. How does it feel?"

"Feels, so fucking in-incredible! Damn!"

Natsu panted as he spilled everything he had into her panties, the front now drenched and sticky. He looked down at himself, seeing the mess he made. It made his cock twitch, knowing Lucy was loving the show he put on. His head fell back, a relieved breath passing his parted lips. His release felt amazing, made better by the fact that Lucy finished before him and got to live out one of her fantasies.

His heart slowly returned to normal, the flush on his face, neck, and chest fading as he calmed down. Natsu grinned when Lucy laid next to him, wrapping an arm around his middle so she could pull herself closer to him.

"Such a good dragon," Lucy mumbled, making Natsu's heart flip in his chest. "You did so well. I'm proud of you, you know that? I'm lucky to have you."

"I'm all yours," Natsu whispered, his body feeling light when she gave him a squeeze. He loved when Lucy was dominant. It was sexy as hell, but he craved her cuddly side more. She was very affectionate after sex, placing languid kisses over his heated skin as her fingers pet his stomach, showing him how much she appreciated him playing along with her fantasy.

Wrapping an arm around her, Natsu tucked her into his side, pressing a kiss to her sweaty forehead. He didn't realize she had gotten so worked up too, both of their bodies exhausted and in need of a hot shower.

Despite that, they didn't move. It wasn't long before the couple fell into a deep sleep, their mess forgotten and their bodies tangling together. They didn't mind. It wasn't like it would be the first time they woke up and had to clean up the aftermath of their session.

I wrote this story for myself, but I figured I could share it in case anyone else was interested in reading it. I won't be offended if you skipped or skimmed it. If you want, you can leave a guest review if you wish to keep your comments anonymous. :)

So, what do you think of this one-shot? I know it was a little out there, but as I post more chapters I start to feel more comfortable writing about different things. I know it's not everyone's preference. If you didn't like the particular kink but still read the whole thing, could you tell me what you thought of the rest of the story? For those that enjoyed the kink, let me know what you thought! I love hearing from each and every one of you! Thank you so much for reading.

Warning: Don't let someone take semi-nude/nude/sex pictures of you unless you 100% trust them, and even then you have to be careful. It's very risky letting someone capture you in an intimate moment like that, and the damage done if those pictures get out can sometimes be irreversible. Be very cautious with who you trust and let in. Your body is yours, and at the end of the day, it's your choice what happens with it. Please protect yourself and think twice about who you let snap those pictures or who you send those types of pictures to.

I've personally had some of my pictures/videos seen on accident, and let me tell you, it was devastating. The person I gave them to was someone I trusted, but accidents still happen. (His family found them) Just really wanna get the point across that even if it seems like a fun/sexy idea, really think about your actions and the possible consequences of them. Actually, that advice can be applied to just about everything. Just be careful. Not everyone has your best interest in mind.

Once again, please let me know what you thought of this one-shot!
