Here's another smutting story, sorry it took me so long, but I'm back and will be writing a few more NaLu one-shots for you all, so be patient and please leave comments and any requests.

Warning this is a Smut fanfic, its rated M for a reason.

I knew she was going to be trouble as soon as I saw her. Blonde hair, tight fitted shirt and short skirt, her laugh filling the room as soon as she entered. Her smile lighting up every space.

I was fucked.

I was also her professor.

But I'm only six years older. And she's legal maybe not since she's my student. But I would not let her down by being easy on her. And that maybe be the problem, I don't think she likes me because I some hard on her, I try and even it out but all I can do is focus on her.

On Lucy.

Lucy Heartfilia.

I don't know why my professor has it out to get me but he seems to always make me do the extra work, even the extra credit! Which I didn't even need! I probably worked the hardest in his class, most of the girls and some of the guys being to distracted by his looks to even pay attention, I was like that at first but it quickly changed as soon as I realised what a jerk he was.

I'll admit his hot and somehow he makes pink hair work and he pulls off his plan button downs and slacks that he should just be asked to model for the company, I actually wished he'd take that job just so I could get a break from his overbearing nature of wanting me to answer everything, like come on, I'm not the only person in the room.

I hate that last point. I always say it when I'm bitching about him around my friends and every time that give the look or a giggle or even outright saying that maybe to him I am the only person in the room. Like he would like me! Plus I'm his student, wouldn't that be breaking a law or something?

"What did you get?" Levy asked me as I practically stormed past her, out the library door and towards the classrooms. "Lucy?"

Levy quickly caught up to me panting.

"He. Fucking. Failed. Me." Lucy growled out through clenched teeth. Levy stopped, pulling her to a halt as well.

"Seriously?"

"Do I look like I'm kidding?"

"Maybe it was a mistake?"

"Oh, it better fucking be." Lucy began to walk towards the classrooms again.

"Do you want back up?" Levy called, half jogged to keep up with Lucy's strides.

"No, I don't need any witnesses to murder," Lucy muttered, not noticing Levy stop and smile before walking back to the library.

All classes were finished and most professors would also be gone by now but Lucy knew that he would be still in his office working. Lucy couldn't think of what he would be doing, but he seemed to always find something.

Lucy's rage was building as she stormed up two flights of stairs and down the corridor until she was standing in front of Professor Dragneel's personal office. Lucy thought that maybe she should breathe and approach this respectfully but that flew out the window as the door opened to reveal her Professor leaving his office. A frown on his face.

"Oh no, you don't!" Lucy barked, she stood toe to toe with her professor her finger pointed straight at his face.

"Miss Heartfilia." Her Professor nodded towards her as he said her name in greeting. "How can I help you?"

Still, pointing her finger at him she shoved it close as she started yet another rant about her professor but this time it was in front of him.

"You 'failed' me? I have been the most hardworking student in your class even when you weren't hounding me with stupid extra credits I didn't need, making me answer nearly every damn question in your class, making me show all of my work to the class, actually giving me extra work after I finished the original but not to others, like what is it that I did to you? Why are you making me suffer through this class by doing all of this shit, and act like I'm the only person in the room? What the HELL DID I DO TO YOU!" Lucy let all of the rage of the past few months storm out of her as she yelled at her teacher, she huffed folding her arms looking at the perplexed look on her professors face. She wasn't going to back down, nor apologise for what she said, she technically didn't say anything mean anyway.

"I failed you because I wanted to talk to you with no one around." Her professor said after waiting a few moments when she finished.

"Talk? About what?" Lucy asked frowning, she tried not to think about how close she was to her professor and how she had to look up to him.

"Uh." He pushed his hair back through his hair, Lucy couldn't think of why his hair looked fine before. "Um." His eyes found hers and he brought his hand down and started to lean forward, Lucy breathed deeply, relishing it's sweet and smokey smell as he leaned close until the breaths were the same. "Lucy"

Lucy didn't know if it was a question or a statement as she had her eyes half closed she watched as her professor looked from her lips to her eyes and finally pressed his lips against hers. His lips were so soft and gentle as he slowly kissed her, Lucy wrapped her arms around his neck pulling him closer to her, kissing back with a bit more passion. Her professor replied by groaning and wrapping his arms around her waist. Pulling her body closer to his. Lucy gasped at the feeling of the solid muscle under her professor shirt which let him get his tongue into her mouth. His hands grabbed her hips running down to her thighs, and he quickly stopped kissing her to pick her up, wrapping her legs around his waist, and started kissing her along her neck and shoulders as she walked back into his office shutting the door behind him. He walked her towards his desk, sitting her on top of it as he leaned down to keep kissing down her collar bone. Lucy gasping as she pulled gently on his hair.

"Professor?" Lucy gasped as he left yet another mark on her neck.

"Please call me Natsu," Natsu instructed still kissing along Lucy's neck.

"Are you sure, Sir?" Lucy asked causing Natsu to pause and raise to meet eye to eye.

"I think that should be my question," Natsu smirked. Lucy smiled back.

"Oh, I'm all for this." Lucy smiled resting her hand on Natsu's chest. "Just me calling you Natsu? Sir?" Lucy added an extra flirting tone when addressing Natsu as 'Sir'. Natsu could see the lust in her eyes, and he couldn't deny how much it affected him when she addressed him as 'Sir'. He must have been taking a few seconds to long as he suddenly felt something rubbing him through his pants.

Lucy's eyes fluttered as she stroked his harden lengthen through his pants.

"It seems to be causing the desired effect, Sir."

Natsu could only grunt in agreement as he watched Lucy slip off his desk, pushing him back so she could sink to her knees in front of him. He watched as Lucy slowly pulled his buttoned shirt from his pants, as she worked the button of his slacks and zipped slowly down his fly. The whole time Lucy looked back up at him innocently. She palmed him through his pants before pulling both his pants and underwear down in full sweep.

Lucy's mouth watered at the sight of her professor's cock. It was standing at full attention, twitching at the feeling of her breath on it. It was much larger than she seen before and she was sure her professor would have much more experience than her. Lucy didn't try to think about what was actually happening, she had had many dreams of her professor, and she wasn't going to avoid her fantasies of him, 'Sir' being one of them.

"Is this okay, Sir?" Lucy asked him as she grasped the shaft of cock, letting her mouth be only a centimetre away from his tip, her breath pushing against. She could feel it throb in her hand, her hand not even being able to wrap fully around it. Natsu could only moan as he watched and felt Lucy's tongue lick the tip, not giving him a chance to answer. She proceeds to lick from the base to the tip, finishing off by swirling her tongue around the tip, allowing it to slowly sinking into her mouth.

"Fuck." Natsu moaned, hands in her hair, trying to restrain from thrusting into her mouth as she slowly worked his length into her mouth and down her throat. She grinned and moaned along with his moans and his thrusts. Trying to hint at him to help her out in taking him down her throat. Natsu quickly got the hint and gently thrust into her mouth, causing Lucy to moan as she mimics his thrust with her fingers within her.

Natsu swore again but pulled out Lucy halting her own ministrations frowning as she was getting close.

"Sir?" Lucy asked wiping her mouth on her arm she looked up at Natsu who bent down picking her up and placing in on his desk again.

"I was about to cum," Natsu informed her as he slowly sank to his knee in front of her. A shiver went up her spine as she watched her professor sniffing and kiss along her thigh towards her knee and down her leg.

"I would have handle it." Lucy muttered as she shuddered and the soft touches her professor was caressing her with as he slowly pulled off her shoes and socks, preceding to kissing his way back up her legs.

"Oh, I know," Natsu muttered back leaving a mark on the underside of her knee. "But that will come late, maybe after a date or two."

Lucy blushed but didn't get a chance to respond as Natsu suddenly pulled her to the edge of his desk and pressed a hard line up her clothed core.

"So sweet." He groaned warping his arms around her thighs to hold her down as she bucks up to meet his hot breath.

"Oh. Please." Lucy gasped her hands know in his hair, pushing him closer to her core. Natsu obliged licking and kissing along her clothed clit.

"So wet," Natsu noted as he pulled back, along with her underwear. Natsu below on to her bare core causing Lucy to curse with a buck. Grinning Natsu plunged a finger into her wet core, it sucked his finger in. Natsu groaned kissing and tongue the outside as he worked his finger in and out of her. Lucy moans the whole time. Natsu added another finger, licking up all the juices that fell past.

"Fuck" Lucy moaned grasping his hair.

"Are you going to cum, Lucy?" Natsu asked adding another finger and watching her face. Her face was scrunched up lost to the feeling of his fingers pumping into her.

Lucy nodded in reply.

Smirked and stopped his fingers but didn't remove them from her pussy.

Lucy's eyes shot open and stared at Natsu, her eye blown wide with lust.

"Please," Lucy begged, rubbing her self to get any sort of friction. "I'm so close."

Natsu only smiled nodding as he started right where he left off.

Lucy noted how he used a stupid technique to see if the student was paying attention, she tried to glare but he defiantly knew what he was doing as she finally found her realise. Crying out her Professors name she watched through hooded eyes as her professor rose, sucking on the fingers that had just been in her. She whimpered still watching as he slowly unbuttoned his shirt and slip it off. He moved to stand in between her legs arms braced beside her.

"It seems you have more clothes on then I do," Natsu said eyes racking her form. Lucy couldn't stop the pang that echoed to her core. As she sat up a bit to pull her top off and unclasp her bar. As soon as she chucked it behind her Natsu was instantly on her, kissing down her neck again while his hands massaged her breast. They were defiantly bigger then most and Natsu wasn't going to deny how much they sweetened the deal. As he praised then as much as he could by suckling and pinching her nipples. He listened to her noises finding the things she likes the most.

"Good, Fuck me already sir." Lucy cried her nails digging into his back.

Natsu raised up kissing her fiercely as he used his hand to line himself up, he rubbed his tip along her awaiting folds, feeling the sucking pull of her wanting pussy. Lucy groaned and bit down on his lip and Natsu thrust his cock into her.

Natsu groaned into Lucy's neck as she moaned wrapping her legs around his hips helping him bottom out in her.

"Fuck." Natsu cursed again as he tried not to cum.

Natsu pulled back leaving the tip in and plunged back into her.

Lucy cried out crawling at his back causing Natsu to growled and thrust harder and faster into her. He watched as her tits bounced in the rhythm of him fucking her groaning every time Lucy clenched a bit more around her.

"You ready to cum?" Natsu asked in between thrusts

Lucy could only nod, Natsu didn't care this time as he stood letting Lucy lay back on his desk as he fucked her, listening to her cry out "Sirs" and "ohs" every time he changed up his rhythm. Suddenly she came yelling.

"Professor!"

Natsu shoots his load deep into Lucy as the sound of his title and the risk they were taking making it more exciting.

They both panted harshly. Natsu pulled out and found a cloth to clean Lucy up before they helped each other into each other's clothes.

"So, um.." Natsu drifted off hand fisting the back of his hair, still roughed up by Lucy.

"A date would be nice," Lucy suggested smiling up at him, she had a blush on her cheeks that made Natsu want to take her again. "After you fix my mark though."

"Already had before I was leaving." Natsu grinned grabbing his bag and Lucy's hand as they walked towards the exit. "I know this really nice place, the cook is amazing he goes by the name Natsu."

"You can cook."

"I may need some help."

Lucy's laughed echoed down the hall.
