Shush

Lucy sighed as she flipped a page in her text book, wishing there was an easier way to absorb the knowledge. She loved learning, but some subjects were more boring than others, especially when the subject wasn't going to be used in her future.

'You're already halfway through the semester. Just keep going and it'll be over before you know it.'

She smiled when she heard a groan beside her, not needing to look over to know who it was. Natsu, her boyfriend, was sitting next to her at the table, studying for a test he was taking tomorrow.

"This is soooo boring," he drawled, earning a few glares sent his way for the disturbance.

Lucy looked at him, poking his arm to get his attention. She placed a finger over her lips, letting him know he needed to be quiet. They were in a library after all.

He grumbled before slumping back in his chair, eyes wandering around the room. Lucy's attention was already back on her book, knowing she needed to concentrate if she wanted to pass this class. She had big plans for her future, which meant she couldn't afford to slack off.

However, Natsu thought she deserved a break.

Lucy jolted when she felt a warm, large hand placed on her bare thigh. She didn't look down, used to Natsu's touches. She tried to focus on her book again, but she soon felt her attention slipping when that same hand started sliding against her skin. Her heart beat a little faster, but she could still push forward, knowing Natsu wasn't going to do much more since they were in semi-public.

There were no tablecloths to stop anyone from peeking under and seeing his hand on her thigh, slowly making his way towards the hem of her short skirt. His fingers brushed against the material, pushing it up before dipping inward.

Lucy finally tore her gaze away from her book, giving her boyfriend a curious look. His eyes were on a study guide he had pulled out, pretending he wasn't doing anything wrong. He wasn't fooling her. She could see the twitch in his cheek when he touched the skin where her thighs were pressed together.

'I should study... On the other hand, I guess I could afford a short break.'

Deciding she wasn't above having a little fun, Lucy allowed him to separate her thighs, spreading them a few inches. Cool air grazed her panties for a moment before his finger tips followed, leaving a trail of fire against her skin.

Lucy took a deep breath, parting her lips when he drew small circles over her clit. Her heart began to race just as heat pooled in her lower stomach, but she kept her composure well. If anyone had glanced in their direction and saw above the table, they would look like two college students studying.

Now, if they were to look under, that would be a different story.

Feeling brave, Natsu pushed Lucy's panties aside, feeling the folds of her sex directly. The skin didn't feel wet until he pushed a finger into her, her natural juices coating his skin. He smeared it over her pussy, imagining the glistening flesh.

Lucy gave up on trying to read her book as soon as Natsu sunk a finger into her core, sending jolts of pleasure throughout her body. It only increased when he pumped in and out of her, purposely focusing on the part inside of her that made her see stars. It wasn't long before he was coaxing her to moan, his fingers not letting up their assault.

'Yes! Right there, Natsu! Fuck, he knows just where to touch me!'

She had to bite her bottom lip and grip the edge of the table to keep herself from giving into that urge, knowing the students around them would easily hear her. It was nearly silent in the library, the only sounds coming from the footsteps of students or the turning of pages.

Lucy swallowed thickly when Natsu added another finger, slowly stroking her inner walls to keep from making too much noise. She wished he could go deeper, but the awkward angle prevented that. He didn't let that stop him from pleasuring her, dragging his fingers along her slit and dipping into her wet heat.

'Oh damn! Fuck that feels great! Please keep doing that!'

A sigh she couldn't contain slipped past her lips when Natsu's fingers returned to her clit, giving the sensitive skin a gentle rub before lightly pinching her. Lucy's eyes widened when a student one table away looked up at her face, then turned their gaze downward, no doubt seeing the show Natsu was putting on.

As if it wasn't obvious enough, Natsu stopped touching her long enough to push her skirt higher up, guaranteeing she would be seen by anyone who decided to take a peek. His fingers were back on her a second later, pleasuring her in no time at all.

The dark haired male didn't tear his eyes away from her exposed pussy for a few seconds, his face flushing before he looked down at his own book. Lucy thought Natsu would have stopped then, but it only seemed to spur him on.

Natsu collected more of her arousal before spreading it over her clit, rubbing the bundle of nerves until it swelled with need. Lucy did her best to hold back her whimpers, failing when Natsu mercilessly drove his fingers into her core again, rubbing along her walls.

'Damn, this is embarrassing, but I don't want him to stop.'

The male from earlier looked up again, his eyes darker than before as he glanced between Natsu and Lucy. Natsu wore a sly grin as he pumped his fingers into his girlfriend, his cock straining against his jeans at the idea of someone watching them.

A girl also looked up, her wavy brown hair slipping over her shoulders before she brushed it behind her. Her eyes flitted before finding the source of the noise, seeing Lucy's legs spread shamelessly as Natsu continued to finger her. The brunette smiled at Lucy before returning her gaze to her book, clearly not bothered by what she witnessed.

Lucy couldn't deny the heat that flooded her body when she knew someone was watching her. It was something they had talked about maybe doing in the future, but she never imagined the first time would be in the school's library. She wished there were more sounds around them to cover the moans she had to suppress, desperately wanting to wail when he played with her clit again, her juices leaking onto the chair.

'Fuck! It feels so good! Holy shit!'

Lucy looked at the guy watching her, seeing he had an obvious tent forming in his shorts. She turned her gaze to the girl from earlier, shocked when she saw her thighs were squeezed together as she squirmed in her seat. Lucy was just about to tell Natsu they should probably stop before they attract more attention, but her words died in her throat when she felt the familiar coiling in her stomach.

'Yes! Fuck! Please! Please make me come!'

Her thighs shook as Natsu's fingers sped up, not giving her a moment to catch her breath before he was bringing her to the edge. Lucy lowered her head, blonde hair falling around her as she bit her arm, muffling the sounds that came with her orgasm.

'YES!'

Lucy felt her legs going stiff as her body sung with pleasure, her nerves on fire and her heart pounding wildly. Natsu drew out her climax, fingers lightly pumping into her dripping core.

She finally sat back up when Natsu removed his fingers, fixing her panties before tapping on her thigh. She slowly closed them, feeling her energy draining as the post-orgasmic bliss overcame her. Looking up, Lucy expected to see Natsu smirking at her, but instead she saw him inserting a finger into his mouth. He kept her gaze as he sucked on his finger, lapping up her arousal.

Lucy couldn't stop herself from looking over, seeing the guy was now leaving, a large bulge in his shorts. Her eyes fell to the girl, seeing she was also heading out, her face a bright crimson. She gave Lucy one last look before winking, causing Lucy's flush to darken. Then their two witnesses were gone, leaving Natsu and Lucy alone to deal with the aftermath of what they did.

Gulping, Lucy attempted to straighten herself up. She looked over at Natsu, not surprised when he grinned at her, flashing his sharp canines. Shaking her head, Lucy packed her book and papers into her backpack.

"You're done studying?" Natsu feigned innocent, excitement thick in his voice.

She shook her head as she silently laughed, knowing there was no way she was going to get any real studying done when she was in this state. Right now the only thing Lucy could think about was getting Natsu back to her dorm room so they could carry on where they left off.

Only this time, she wouldn't have to be so damn quiet.

Let me know what you thought of this one-shot! :P This is my shortest one for nalu love fest, but I still like it. :)

*In case anyone was wondering, the guy and the girl were Gray and Cana. In that AU they don't know each other. :P
