Summary:

Lisanna is back and Lucy is feeling very lonely. After one drunk night with Natsu, Lucy's heart breaks. She leaves the guild looking for a better future but will Natsu let her? Post Tenrou.

Disclaimer: If I was Hiro Mashima, Nalu would have happened from the beginning. Since I am not, Fairy Tail is (unfortunately) not mine and Nalu is slower than a snail.

A/N: Rated for a reason. First time writing lemon, the scene isn't supposed to be too graphic. The idea is that they did it, and the plot can progress. The better, longer ones come later. No flames please. Haven't wrote a fanfic in forever.

Chapter 1

"Child, are you sure you want to do this?"

"Yes master. I need to have a long time to think, alone. Right now there are too many possibilities. I can't stay here any longer."

The master sighed, a sorrowful look taking over his face.

"You are not going to tell him?"

"No, not now. Maybe someday, but not now."

The master sighed again before giving her one last glance.

"I hope you are making the right choice. Remember, our doors are always open to you."

She gave a half-smile.

"Thank you master, good bye"

The door shut silently on her way out.

- Three weeks prior -

"Hey Lisanna" Natsu called from the entrance, "Wanna go on a mission today?"

Lucy sat at her regular chair by the bar observing the interaction between the two as Lisanna skipped happily to Natsu. Lisanna was a really nice girl. Lucy didn't blame Natsu for being elated by the fact that she was alive. However, as the weeks passed, Lucy definitely found out that a life without Natsu was very hard and mostly boring. She missed her idiot teammate who was a destructive fireball everywhere. Although Natsu did some pretty stupid things, he cheered her up and always made her day happier.

Lucy sighed as she watch Natsu take a mission off the board to give to Mira. Before she could mark down the quest however, the guild doors banged open with Gildarts walking in.

"Hey listen up! We are having a party today! As you all know, our S-class exams are only a few weeks away. Master said to give you all a breather before exams starts. This is the last time you have to go wild for a while, so party hard!" With that, Gildarts motioned outside where Erza was carrying a huge boar.

"All right! I'm all fired up!" Natsu yelled.

"Lisanna do you mind if we do the mission tomorrow then?"

"Sure that's fine." Lisanna replied.

Lucy still sat by the bar, the crowd was getting hyped up but she wasn't in the mood to party. If anything, she just wanted to go home and climb into her bed and sleep. There were already fights breaking out between the partygoers and the commotion was giving her a headache.

"Lucy, why don't you go have some fun?" Mirajane asked.

Lucy smiled weakly, "Thanks Mira, but I'm not in the mood right now."

Mira smiled back, "Don't worry, this will pep you right up."

She slid a glass of clear liquid towards Lucy. Lucy stared at the glass. It was probably alcohol but what was the worst that can happen?

My life is already screwed as it is.

Mind made up, Lucy grabbed the drink and uncharacteristically chugged it down.

"Thanks Mira, that was very refreshing."

Lucy returned the glass and walked towards the party crowd. She could already feel the effects of the drink on her. Her mind was relaxed, and she began dancing with the music. As other guild members crashed and fought around her, she didn't mind like she usually did. Instead, she spotted Levy on the corner and dragged her onto the dance floor. Soon the commotion died down and the fights that were happening at the beginning of the party ended. Most people were dancing now. Couples held onto each other while singles danced in a group. Feeling slightly lightheaded, Lucy decided that now was as good time as ever to start heading back. Quietly saying goodnight to Levy and Mirajane, Lucy slipped out the backdoor.

The night air was frigid. The coldness created goosebumps along her skin. Very few people were out at night, and for the ones who were out, they rushed with a sense of purposefulness. Lucy walked along the edge of the canal, humming one odd tune or another. Soon, she arrived at her apartment and went in. It was warm, in fact warmer than it should have been. Heart beating quickly, Lucy made way to her bedroom. A rush of cold air hit her but that was due to the window being open. The room itself was stifling hot.

A shadow nearby moved, and Lucy jumped in surprise before realizing that it was Natsu.

"Natsu, did you follow me here?" she asked in an exasperated tone.

"You left the guild before the party was over." He simply stated.

"That wasn't what I asked." Lucy replied, but Natsu remained silent. His stare fixed on Lucy. Lucy felt her heart start beating rapidly and a blush stained her cheeks. In the moonlight, Natsu's normally onyx eyes glowed gold.

"Why are you here?" Lucy tried to ask again.

Again, Natsu didn't answer. Instead, he stepped closer and closer until he was right in front of Lucy. She could smell the telltale scent of alcohol on Natsu.

"Natsu did you drink? You know that's – " She was cut off as Natsu engulfed her in a hug.

"Mine." He growled possessively.

At this point, Lucy could definitely feel that heat on her cheeks. She was surprised that she hasn't exploded yet. Before she could do anything else though, Natsu started kissing her. His lips demanding and hot as he pulled her even closer to him. Lucy moaned and Natsu took advantage of it to taste her inside. He was hot, his temperature was rising. In the back of her mind, Lucy knew this was a very bad idea. Alcohol always lead to bad mistakes. She tried to protest, to shove Natsu off her, but he was too strong.

Natsu soon had Lucy pushed onto the bed. She struggled, but her efforts were getting weaker at each attempt. The drink she had earlier had fogged her brain and all arguments flew out when Natsu began to suck gently at her neck.

"Mine" He whispered again.

He was looking directly at her this time. His odd golden eyes staring into the chocolate orbs. Lucy couldn't keep it in.

"Natsu …" She moaned.

His eyes began to become even more intense as he undressed her. His touch this time was tender, unlike the forceful way he had kissed her earlier. Once Lucy was completely devoid of clothes. Natsu began to kiss down her neck. He kissed her breasts, stomach and thighs before going to her nether regions. He suckled and played with his clitoris, making Lucy moan squirm. As he began lapping at her folds, Lucy tangled her hands into his hair. She could feel her release it was so close. When Natsu began thrusting his tongue inside, Lucy lost it. She screamed his name as she came and rode on the after waves of orgasm.

Natsu crouched over her and gave her another kiss. They each battled for dominance before Lucy relented. Once they broke apart for air, Natsu began taking his own clothes off. When he was done shedding his clothes, Lucy found herself enraptured by his member. It was big, long, and hard. Absentmindedly, she wondered if it will fit. As she made an attempt to reach it, Natsu grabbed her hand and pinned it above her head. He came down and captured her lips for another kiss before rubbing himself against her. Lucy moaned and began grinding against him. Natsu entered her within the next minute. Lucy winced at the pain but Natsu didn't stop. He was like a man possessed, and kept thrusting into her. He was back to his original demeanor, his kindness gone. His thrust was forceful and hard, and Lucy was in pain at first. But she soon got used to it and found the rhythm between them.

"I love you" Lucy whispered.

Natsu grunted in reply. They came together, Natsu emptying himself inside of her. Lucy was exhausted, and she soon fell asleep surrounded by heat.

NEXT DAY

The next day, Lucy woke up feeling very sore. Her bed was cold and her windows were open. The recollection of last night hit her like a train. Lucy didn't know to cry or jump in elated happiness. She quickly took a shower and prepared her best outfit for the day. Vaguely, she wondered why Natsu did not show, but waived her thoughts away since she will be seeing him at the guild. Humming a happy tune, she quickly did her hair and headed the way towards Fairy Tail.

She sat in her usual spot at the bar, brimming with cheer. Mirajane fixed her up a small breakfast as she waited for Natsu to show up.

Soon enough, the guild doors banged open and her favorite pink haired dragon slayer walked in. Lucy pretended not to smile at him and resisted the urge to fling herself into his arm. She covertly glanced from her breakfast as he walked towards the bar.

"Good morning Na –" She was cut off as Natsu walked past her to yell into the kitchen.

"Hey Lisanna! You ready for the mission?"

The white hair mage soon came out.

"Yeah, give me a minute to wrap up some stuff." She replied before walking back in.

"Hey Natsu." Lucy greeted again.

He glanced over at her, as if he just noticed she was there.

"Oh hey Luce. Crazy party last night huh? I am so glad that Lisanna was able to take care of me and get me back home."

Lucy's face fell and her spirit plummeted.

"Do you remember anything last night?" she asked.

"No, not really. My memories are pretty vague. But I'm sure Lisanna took care of me. She always does, back then and even now."

"Ah I see." Lucy replied as she tried to reign back the tears that were threatening to come out.

"By the way, do you mind if I go on missions with Lisanna for a few more weeks till the S-class exams? I want to help her adjust."

Lucy remained silent. She didn't trust herself to say anything. She gave a quick nod and an excuse to use the bathroom. Once inside, Lucy began to cry her heart out. He had forgotten everything. He thought it was Lisanna who took care of him even though he had such an intimate moment with Lucy. Her heart broke at the thought. Even though she knew Natsu was dense, she always wondered and feared if Natsu and Lisanna would get together. Their bond was so strong and they have known each other since they were kids. Lucy was determined to not let her feelings show. If that happened, she would probably break down. However Natsu was her friend, and even if he never returned her feelings, she still wanted him to be happy. She knew from his actions and his word that they will never be the same again. If the time ever comes, she would support Natsu in whatever decision he made. But for now, she would mourn the loss of her best friend and the future they will never have.
